Language Paper Essay Language can be looked at differently from other types of cognitions. There is a need for language in one form or another to have the ability to communicate with other human beings. This communication is the basis to how human beings express themselves to those around them. With this expression comes the ability to formulate thoughts. These thoughts can be translated to others through language. This language play an important role when analyzing, problem-solving, creating reasons, communicating needs, and making plans. Without the existence of language the attempt for humans to achieve goals would be almost impossible to accomplish. Goals would have to be accomplished be figuring out an alternative method than language to be used for sciences, history, mathematics, and the ability to explain past experiences or cultures. Because language is such an important communication tool, this paper will go into the definition of language and lexicon, evaluating the key features of language, with a description of the four levels of the language structure and processing, and analyzing the role of language processing in cognitive psychology. . Define Language Because there is so many different ways of language it can be difficult to provide just one. Cognitive psychology defines language as a system of communication that is governed by a system of rules and can express an infinite number of propositions. In addition, natural language has two criteria. First it must be governed by a set of rules knows as grammar. Second it must be productive – an infinite number of things can be expressed (Galotti, 2015). But there are some factors that are deemed to be critical in the communication of human language. The factors that are deemed critical are: communicative, arbitrary, structured, generative, and dynamic  (Willingham, 2007). These critical items that are necessary for the formation of language starts with communicative. Communicative will allow communication between individuals. Arbitrary which means that a sound will stand for a meaning. Language, which needs to be structured and must follow a logical order to make sense. Generative which means that there are a limitless number of meanings that are associated to the word. Dynamic which means that language is constantly changing, growing, and adapting (Willingham, 2007). Define Lexicon Lexicon is defined as the mental store and is thought to be the keeper of the cognitive processor’s knowledge of words, which also includes the spelling, pronunciation, definition, and parts of speech (Galotti, 2015). Most researchers have a belief that when people recognize words through the process of matching where the spoken word will be compared with a mental dictionary. This mental dictionary is known as the lexicon. The lexicon is the foot bridge between language and knowledge (Willingham, 2007). This communication bridge for lexicons will vary depending on how and where a lexicon is used. However, the grammaticalizations will be different depending on the type of language being used. The words and expressions used in each language will be the lexicon for that individual language. Therefore an individual person’s own set of vocabulary would have their own personal lexicon attached to it that would be their own personal storage unit of their knowledge. Evaluate Key Features of Language Charles Hackett identified 13 features of human language and how the human language is differs from other forms of communication. Four key factors are vocal-auditory channel, specialization, arbitrariness, and traditional transmissions. Vocal-auditory channel is defined as the means that the standard human language occurs vocal (creation of sound by mouth) type of communication that can be perceived by hearing it (Hyde, 1998). Specialization is the use of organs in the production of speech and these organs are able to adapt to the task of speech. Example would be the lips, tongue, a throat of a human that have been specially adapted to the task of speech and not just to assist as an eating apparatus. Whereas, dogs do not  have the physical capabilities for the speech sounds that humans have the capability of because dogs lack the necessary specialized organs (Hyde, 1998). Arbitrariness is where there is no necessary connection between form of the signal and what is being referred to. An example would be a very large object like a whale and yet it is referred to with a very short word. Some would argue that four-legged animals could then be referred to as the sounds they make. However, the sounds animals make do not always translate across culture borders and therefore even onomatopoeic words would be to some extent also arbitrary (Hyde, 1998). Traditional transmissions has the meaning that human language is not something that exist from birth. Even though language does not exist from birth humans are born with some ability to perform language. In order for humans to perform language they will need to learn, acquire, the language that is spoken around them from others who speak the language. Learning language by listening to others is different from the communications in the animal world. In the animal world animals are born knowing their entire systems. Such is the case with bumble bees who are born with the knowledge of dance and song birds that are born with the knowledge of bird-songs. Describe the four levels of language structure and processing The four levels of language structure and processing are phonemes, words, sentences, and text. Phonemes is the shortest segment of speech that if changed would change the meaning of the word (Goldstein, 2014). There are 44 phonemes that make up the basic unit of sound (Galotti, 2015). The basic unit of sounds will vary from different languages. The study of the different ways that phonemes can be combined in any language is called phonology. Once you have put the sounds together the task then becomes to put the sounds in a coherent way, identifying the meaningful units of language and this aspect is known as morphology (Galotti, 2015). These sounds then become words, sentences, and text. Words should be placed in a sentence will have importance to the understanding of the sentence. Text will be a group of sentences that once placed together will be the formation of the paragraph in reference to a certain subject. Analyze the role of language processing in cognitive psychology How humans process information is a key factor in cognitive psychology. Language is what is used as the main source of communication for humans and is influenced by both internal and external factors and since cognitive psychology is the investigation of all mental abilities the processing of language plays an important role. There are two different proposals in regards to the relationship of language to other cognitive processes. The modularity hypothesis proposed that there are some aspects of language, especially syntactic processes, will function autonomously, and independently of any other cognitive process. This recent proposal awaits a more rigorous empirical testing even though there is some evidence does exist. The second proposal is the Whorfian hypothesis of linguistic relativity, even though it is very interesting it has so far not received strong or empirical support (Galotti, 2015). Cognitive psychology is the science of how the mind is organized to produce intelligent thought and how the mind is realized in the brain (Anderson, 2015). With cognitive psychology being the study of how the mind is organized to produce intelligent thought this knowledge is through either written or verbal communication. The written or verbal communication through language enables an individual to communicate thoughts and emotions. It is these thoughts and emotions that cognitive psychology attempts to understand. Conclusion Language is a system of communication that is governed by a set of rules and can express an infinite number of propositions. Natural language has two criteria. First it must be governed by a set of rules knows as grammar. Second it must be productive – where an infinite number of things can be expressed (Galotti, 2015). Language plays an important role in the regards to cognition because it is the main communication tool used by human beings. Language has to have a storage place where pronunciation, definition, and parts of speech are stored. The storage place is called the lexicon. Lexicon is the bridge between language and knowledge. Language is a system of communication that is governed by a system of rules (Galotti, 2015). There are 4 levels of language, structure, and processing. In addition, Charles  Hockett identified 13 key features of the human language. The ability to turn language into communication through words, and then pull information from a person’s experiences, education, environment, and culture is a magnificent feat to accomplish, and it is through language that people are able to express their ideas because of the role cognition plays within language.

Decision theory Essay Example for Free

Decision theory Essay How could companies use Second Life for new product or service decision making? Companies use second life which includes meeting with the sales manager, discussing about new sales techniques, building a new world where members of second life talk together about product or services and testing the new designs for new product or service before it is released to the world. Thus by taking feedback from all members companies take decisions. . How could financial companies use neural networks in Second Life to help their businesses? Neutral networks are those which involve in pattern or image recognition. This helps companies to get the required information for processing in second life. 3. How could a company such as Nike use decision support systems on Second Life to help its business? Nike uses decision support system (DSS) for information that helps to take decision. But DSS has three main models in it. They are: -Sensitivity: observe changes when variable is changed -What- if? checked what is the impact if variable changed -Goal seeking: seeking to reach goal by making changes. 4. How could an apparel company use Second Life to build a digital dashboard to monitor virtual operations? Apparel uses second life in digital dashboard to monitor virtual operations as it tracks everything in the store which includes number of customers, time spent, items purchased etc. Company also gave a special offer to the second life residents that they get promotional cards if they are shopping in inline-world apparel. Describe how the DoD is using AI to improve its operations and save lives. By using AI the DoD is able to make operations like resupply missions more efficient because human drivers and troops to protect the supply line aren’t needed. AI would also be able to perform dangerous missions without endangering troops. 2. Explain why the DoD would use an event, such as the DARPA Grand Challenge, to further technological innovation. The DARPA Grand Challenge produces lots of different ideas from diverse sources which will produce more efficient technology. The contest is also at a relatively low cost to the DoD because it would cost more than $2 million dollars to produce and test so many models on their own. 3. Describe how autonomous vehicles could be used by organizations around the world to improve business efficiency and effectiveness. If businesses were able to transport their goods without human transportation controllers it would cut costs and eliminate some of the risks from human error. 4. The Ansari X is another technological innovation competition focusing on spacecraft.

The Purpose and Benefits of Classroom Observation

The Purpose and Benefits of Classroom Observation Classroom observation is a process by which the institute of nursing-Academic Support Person(ASP) sits in on one or more classroom sessions, records the instructors teaching practices and student actions, and then meets with the instructor to discuss the observations. The main purpose behind the classroom observation is to allow a teacher to get feedback from an objective, experienced observer and to involve in context-specific discussions about teaching with adviser. The observation should not be an endorsement for promotion and tenure, a judgment of the teachers teaching methods, styles and skills, or an assessment of the teachers knowledge of disciplinary content. It is purely developmental rather than intimidation and making decisions. Classroom observation has been used many years ago to evaluate the quality of teaching provided and the consistency between the curriculum plan and the actual delivery of the material by teachers. Wagg (1999) stated that the purpose of looking at implementation is to see whether there is mismatch between intention and strategies. Classroom observation has constantly been seen as an effortful task from the side of the teachers. Negative attitudes have been expressed from several teachers venting their disappointment about the process by which observation has been implemented. This feeling of unhappiness and dissatisfaction is not a product of today; it is possibly an aggregation of many years of authoritarian, impressionistic, and impartial models of supervisions with teachers feeling of little ownership. Because the observer has a great role in renewing the teachers contracts, they had to conform to the supervisors viewpoints .This is considered an exceptional limitation of the obser vation process. Diverse research revealed that the way teachers behave in the classroom and the instructional methods they use impact the degree students learn. Consequently, using classroom observations, educators and investigators are capable of providing feedback that may improve the teaching practices in the class. Hopkins (2002) considers that the motivation behind any school observation is not limited to classroom research only but it extends to the professional development of teachers. This is because of the many years of observations that contemporary educationalists agreed to desert through time the conventional recitation lesson (Wragg 1999). Clearly, different forms observations encompass different criteria. These criteria may be comprehensive or specific. Some observation forms may focus on the students behavior while others may seek out the response of teachers to such behaviors. According to Hopkins (2002), there are four methods of observation: open, focused, structured, and systematic. Each method needs special instrument. . Observation tools are forms that are to be filled out by the observer. Depending on the observation technique, some forms or instruments may simply be a blank sheet, a worksheet, a scale, checklists, computer software, or a tally sheet. Some observers may be affected by the setting in which the lesson takes place and may focus on some particular feature of the teaching of one specific subject, like science or English. This in turn may influence whether they adopt a quantitative style, which is a type of systematic approach; counting and recording of individual events, or a qualitative method, wh ich is a type of the open observation approach, trying to look behind and beneath the mere frequencies (wragg 1999). Furthermore, there are many observations tools used by teachers on their classes or in peer observation settings (Malamah-Thomas 1987, Wajnryb 1992). Such instruments are powerful developmental tools for teachers and for trainees advisors, allowing both to look at the lesson systematically in conjunction with the feedback from advisors. Therefore, teachers and observers must perceive the instruments similarly to avoid misinterpretations and predispositions of the items within the tools. At the level of the ION, instructors have expressed the issue of the perception of the observation tool many times. In addition to the way the classroom observation is conducted. However, the questions that continue to irritate my colleagues and leave them preoccupied with an answer to them are that, do all classroom observers perceive and interpret the same observation items within the checklist in the same wayà ¢Ã¢â€š ¬Ã‚ ¦?Is there any problem in the observation methods? This actually urges me to investigate these issues in the Institute of Nursing (ION) to find out any discrepancies in the understanding of the observation checklists and or any defect in the observation process. To pursue the task appropriately, the advisors will not be participated in any other job but collecting data. Randall and Thornton (2005) refer to an advisor who has no other than to observe and take notes as a non-participant observer (Gebhard and Oprandy 1999). As the name designates, this kind of observation requires the observer not to engage in any interaction with the individuals being observed. Instead, the observer should concentrate on a particular behavior a specific criterion (Wragg, 1999, Hopkins 1999, 2002). For an observer, it is very important to avoid preconceptions and afterward approach whatever is to be observed with an open mind (Wragg 1999). Due to its direct involvement with the individuals observed, observation does have a benefit; however, it is time-consuming (Robson, 2002). Pre-judgments and predispositions may also produce troubles with observation. Such troubles may lead to misinterpretation of the data being collected (Brophy Good 2003). Therefore, the observer should avoid any personal biases that may contaminate his/her results. In this small scale study, the entire process of observation, from the instrument used by the observer to different stages of teacher observation, was totally decided by the observer and the investigator. The terms observer and advisor will be used interchangeably. Background The United Arab Emirates (UAE) encompass three institutes of Nursing (ION) located in Sharjah, Ras ELkhaimeh and Fujairah Emirates and they are governed by the Ministry Of Health (MOH).According to the policy, the ION has an observation system performed by three persons: the Central Academics Coordinator (CAC), Academic Support Person (ASP)and the Branch Manager(BM). The class room observation is held two times per semester and as needed. One observation is announced and the other is unannounced. At the level of each ION; the observation responsibility is delegated to the ASP. In case the teacher observation result was unsatisfactory, the CAC will be called to reobserve the same teacher within two weeks of the unsatisfactory observation but can also observe those with satisfactory outcomes. The BM does a spot check from time to time on the ongoing of the teaching process. The three observers use the same observation instrument and it is qualititative (open methods) in nature where ob servation bias can sometimes significantly affect the result. The session Appraisal form is composed of 29 items focusing on two areas of classroom practices: Effective Questioning (8 items), Effective Teaching Practices (21 items). These items are marked as, Accomplished, Partially accomplished, and Not accomplished. The final result is either satisfactory or unsatisfactory (Appendix 2). The adopted teaching methodologies are cased-based and lecture-based, depending on the course. Most of the teachers at the ION are well experienced and hold master degree. I have been working as a senior nursing tutor for the last seven years in the ION. It happened more than once a teacher got two or more different feedbacks from the observers. The teachers always blame the observers for their inconsistency in the understanding of the observation items and in the way the observation is conducted. The majority of the tutors wonder whether a difference should be there while using the same observation checklist and the same observation methods. The investigator will try to answer this question and orient the teachers to the findings. Research Questions Is there a significant difference in the perception of the same observation items within the instrument used by the different advisors in the ION? Is there any defect in the observation process? Purpose The investigator will try to: Find out any discrepancies in the observation tool among the observers. Identify the drawbacks of the observation method. Report to the curriculum committee and teachers these inconsistencies (if any). Observation Methods Classroom observation is a collaborative process. Both the teacher being observed and the observer have vital roles before, during, and after the observation. Collaborating at each phase of the process can help put both participants at ease so that each benefits from the experience (University of Washington 1998). Classroom observation is conducted through three phases that were adapted from Day (1993) and Richards and Lockhart (1994) were: pre-observation meeting, observation phase, and post-observation follow-up phase. The researcher will be use the ION designated tool during the observation process. (Fig 1). Pre-conference phase is executed before the classroom observation. The purpose of this meeting to share information that helps both the instructor and observer prepare for the observation and to illuminate the explicit outcomes of the lesson observed. It also aims at clarifying the activities through which these outcomes will be attained. Information exchanged during this meeting includes overall process of the evaluation, the purpose of the observation, course information, lesson plan, instructional objective(s) , class activities, instructional methods, What you want the observer to pay attention to, Where youd like the observer to sit , what will happen during the observation, and observation follow up opportunities. This phase does not take place in the ION. The second stage of the process is the observation phase (Data Collection) or the execution of lesson. The ION observers gather information to be discussed latter with the tutor. These data include instructor doing/saying, students doing/saying, instructional methods, teacher-students interaction, and flow of the sessionà ¢Ã¢â€š ¬Ã‚ ¦etc. Generally, the ASP will use a checklist tool designed for this purpose of classroom observation (Appendix 2). The observers, unlike the traditional supervisors who usually sit at the back and document the classroom events, sit where they can have a good view of the class. Analysis of the collected data and preparing for the post-conference take place immediately, next to the observation, it is suggested that observers code the data checked in their notes. Identify information that links to the following: Organization and presentation of the lesson, level of student concentration, interactions, and participation, the quality of interpersonal relationships between the teacher and students, effectiveness of instruction and how instruction could be improved. The third stage is the post-conference phase or follow-up. Shortly after the observation, the advisors emphasize the positive areas of the observation process such as the strengths of the lesson. The teacher will be asked to evaluate and reflect on his lesson at first. Then, the observers will discuss the collected data with the teacher. It is a descriptive stage where the observers describe the various phases of the lesson. The observers during this phase ask probing questions that guide the teacher through the process. They also provide direct feedback on the areas the teacher has asked for in the pre-observation conference. In doing so, many of the areas for improvement are originally stated by the teachers because they had a chance to reflect on their teaching. Figure Observation Cycle: Adapted from: http://www.commnet.edu/emprel/trng/tm_3_2_clasobs.html (2004). Validity and reliability in observation It is essential that observation is as objective as expected and advisors must be mindful of their own interests and predispositions so that the data gained is as valid and reliable as conceivable and not designated to verify a point (CCC 2004). Observers customarily continue-the-spot notes to complete an observation schedule so that any extra or uncommon actions can be noted. For example A come into the class and talked to teacher, this interrupted classroom for 3 minutes; Fire alarm rang at 2.24pm so the class was shorter today than usual. Field notes are often written post assessment and the advice is to do this as early as possible. Robson (2002) proposes that you should never begin a second class observation before sorting out your records for the first one Practice in utilizing a schedule before the actual observation will assist the observer to settle uncertainties in how to employ it or how to record unforeseen or vague data. Reliability of observation will originate from appraiser consistency. Appraisers have to make sure that they make parallel decisions about similar situations on diverse events. They must also take similar decisions about similar events if they see or hear them again; say on video or audio tape. Preferably, having more than one appraiser observing the same events, at least in initial practice sessions, so that there can be agreement on what is going on and how it is to be coded. The two observers at the ION were aware of these points to ensure the validity and reliability of the class supervision. Limitation of the study It is worthy to mention that the scope of this study is limited to a group of teachers of Nursing in Fujairah campus in an educational zone. Therefore generalization of the study might not be possible. Literature review Even though the classroom observation is seen as a crucial element of each educational system, researchers have found that teachers were not satisfied with the observation process. The main reasons researchers found were judgmental, evaluative nature of observation, authoritative role of observers and prescriptive nature of feedback (Akbari and Tajik 2007). Wang and Seth (1998) found out that classroom observation has gained a negative reputation in the ELT profession because of its subjective, judgmental, and ill-defined nature. Many instructors resent being observed at short notice by important people who judge their performance according to their own, not necessarily appropriate criteria, and make unwelcome suggestions for change. It seems as if these inspectors have the final word on whether their performance is good or bad, right or wrong. In many situations the observers enter the classes to look at the teachers performances to decide at the end of the academic year who will continue in his/her job or not. Certainly, this perception places teachers under too much stress which negatively impacts their performance in classroom. Randall and Thornton (2001) believed that anxiety levels in the lesson execution phase can become very high and can precipitate failure on the side of the teacher to generate an effective lesson (Fig 2). Figure 2: The effect of anxiety on performance (adapted from Randall and Thornton, 2001) Regarding the process of the classroom observation in the UAE, Alwan (2001) find out that the instructors in the UAE are acquainted with the observation; yet, it does not take the systematic approach that would increase the achievements for the teachers. Consequently, such ad-hoc appraisal practices can simply yield extensive teacher anxiety, a lack of belief in the validity of the observation, and a delicate discouragement of other institutional initiatives to sustenance teachers efforts to deliver courses effectively (Murdoch, 2000). Nevertheless, classroom observation should be intended at enhancing professional growth of the teacher rather than threatening them. It should also focus on the strengths of the lesson. The tutors and through their dealings with the students will recall which areas delivered in a good manner and the ones that require revisiting. It is valuable to point out that the advisors role is to explore with the teachers so that they have the chance to reflect on their own teaching with the expectation that this approach will turn into a fundamental part of the teaching and learning process. Therefore, it changes into a reflection in action process that is conducted during the teaching learning process. Schon (1983) explained this reflective process by saying: Both ordinary people and professional practitioners often think about what they are doing, sometimes even while doing it. Stimulated by surprise, they turn thought back on action and on the knowing which is implicit in actionà ¢Ã¢â€š ¬Ã‚ ¦usually reflection on knowing-in-action goes together with reflection on the stuff at hand. (Schon, 1 989) Therefore, classroom observation is getting more importance than before. The purpose of many of them is intended towards professional development. It is through experiential learning that the tutors will be self-evaluative and hence will be capable of reflecting on their teaching strategy. Heron (cited in Randall and Thornton 2001) said that working from experience the client (the teacher) is prompted to uncover incidents which are important, reflect on these incidents and to discover new meanings for these incidents, and then prepare to put the learning from experience and reflection back into new experience. Finally, it is of merit to mention that teachers teach many lessons of which only few of them are observed. Accordingly, If the observed lessons are considered valuable and worthy to be observed then they must be regarded as worthy to be analyzed appropriately, for little purpose was served if, after a lesson, observers simply exude good will, mumble vaguely or appear to be uncertain why they are there, or what they should talk about (Wragg, 1999). Methodology To inquire about teachers dissatisfaction with the overall observation process, a two phase qualititative study was conducted. In the first phase, the observation instrument revisited to see whether the observers perceive its item similarly or not. In the second phase, a questionnaire was distributed to all ION teachers in an attempt to evaluate the method of observation conducted there. Ethical Considerations The ethical considerations were carefully considered before conducting the study. A permission letter was sent to the concerned people to consent them. Anonymity and confidentiality of teachers responses guaranteed (Appendix 3). Part I: Procedures and Participants Two observers visited Diploma I class to assess a teacher teaching Nursing Care of Adults 201.One of the observers is the ASP whose tenure is 11 years and the other is a critical friend who holds a master degree in education and has 10 years of teaching experience. Both are familiar with the observation tool. This approach was used to explore inconsistencies in the perception of the observation items within the specified from. They were informed about the process; they should sit at different corners in the back of the class (Fig 5), do not speak to each other, and fill in the appraisal form the way they perceive it with an evidence for each partially or not accomplished item. Data Analysis At the end of the classroom observation the researcher collected the two filled forms and sit with the two observers to discuss the findings. The data analyzed by utilizing simple statistics, and tables. Results The two forms were collected, and it was found that two items were uneven where each tutor has his own perception. Class Subject Observer 1 Observer 2 Session Time Teaching Method Diploma 1 Nursing Care of Adults/Hyperthyroidism Academic support person, 11 years teaching Experience Critical Friend, more than 10 years teaching 50 minutes Case-based The mismatched items were two out of 29 items; the two items were located under the Effective Teaching practices. See table below: Finding of first observer marked as (1) and (2) for the second Effective Teaching practices Accomplished Partially Accomplished Not Accomplished 26. Asks students to evaluate their own or others responses. 2 1 29. Demonstrate the ability of dealing with problem students 1 2 Observers Justification First observer 26. Asking student to evaluate and reflect on the answers given, getting feedback from classmates should be done frequently in the case based session as this would involve the students in the class and enhance their understanding. This should be observed as a dominant feature in the session and not only once or two. 29. The students were enthusiastic, motivated and participating actively, it was loud voice but not noise, but you have to ask students to lower their voices to hear their classmates .Raising their hands without calling Sirà ¢Ã¢â€š ¬Ã‚ ¦. Is fair enough. Second observer 26. Students were fairly able evaluate their answers and that was done with two students only. As for the responses of their colleagues; the students were called more than once to reflect on their answers when the teacher asked them: 1) Do you agree with S? Why? 2) Why did M relate the presence of excessive eating to weight loss? Comment on her answer. Although, the teacher tried with them, the students were not able to evaluate their responses. 29. Loud voice from the side of the students will disturb the learning environment preventing the others from hearing the answers, the teacher tried to control students noise particularly when they gave answer together, but he could not. Abiding by the classroom norms is the responsibility of the teacher. Setting clear guidelines should be made to limit this behavior. At the back of the session appraisal form there is a room left for the appraisers comment to reflect and set the areas that need improvement on points that are not covered clearly in the observation form but should be part of the lesson or he may emphasize certain points seen in the class. The first observer A) Group work: The teacher should give more time (more than 10 minutes) for the group work to allow the students to prepare and discuss the task properly among them as the task given require deep analysis. Moreover, the teacher should ensure that all the students are participating in the discussion within the group. Checking group work output is not necessary to be done with each group, as far one or two groups were investigated, then the other groups could be done if required by the judgment of the tutor. The Second observer A) Group work: Ten minutes for each task is fair enough as the students should come prepared from their home. The time is given only for discussion and preparing the transparency. Giving more time will waste the teacher time and hinder his ability to cover the course objectives. Group work output was not explored: teacher has to reveal all group findings and seek evaluation or comments from other groups. The first observer B) Teaching strategy The teacher should implement various teaching strategies in the classroom such as role play, watching and commenting on videos to promote students understanding, involvement and make the session interesting. The Second observer B) Teaching strategy The session was quite interesting. According to the task discussed in the session, role play or video would not be effective as the demonstrations used by the teacher plus the clinical examples and the real life examples given by some students were satisfactory to cultivate the different concepts in the sessions. Discussion One method for analyzing the observation findings of the two observers is through triangulation. Triangulation in the classroom research involves checking the perceptions of more than one person to see if ones own interpretations have any support Wragg (1999:111).The total number of the items in the observation checklist is 29, and the debatable points were 2. Then, the agreement was around 93% and disagreement in 7%, which means that the instrument used is reliable. When the observers agree on > 80% of their observation, this means the information and the data are reliable Wragg (1999). It is believed that different style dimensions of learning of the observer may have a possible influence on providing feedback to the teacher. (Randall and Thornton 2001:134). The first observer, the academic support person, conducted more than four observations to the observed teacher, and knows him better than the second colleague. Hence, he built his feedback on his previous knowledge of the learning style of the observed teacher and provided the feedback in a consultative rather than confronting approach, The students were enthusiastic and participating actively, it was loud voice, but not noise, but you have to remind students to lower their voice to hear their colleagues . Part II Procedure: The participants filled a qualititative questionnaire of seven questions (Appendix I). The questionnaire was piloted before being administered. A total of eleven questionnaires were administered through face to face contact with the investigator. Ten of them were collected and analyzed. Participants The participants in this study were ten teachers of Nursing in one of IONs. They have been teaching in the ION for more than 7 years. Those teachers have been observed by three different observers using the same tool. The teachers are male and females and range in age from 36 to late 54. They majority of them are native Arabic speakers from different countries and two teachers are westerns. They are of multi-cultural background. Data Analysis The responses to the questionnaire were gathered and then analyzed. The responses were calculated using simple statistics and presented in charts. Results of the Questionnaire Items No. of Teachers Percentage I have been observed two times by the ASP 8 80% I have been observed three times, two by the ASP and once by the CAC 2 20% I felt anxious and blocked when the observer visited my class 10 100% I am dissatisfied with way I observed. I did not meet with the observer before the session 10 100% The observer was sitting in the back, ticking on the observation form. 7 70% The observer did not tell the students who he is, creating unstable setting in the class. 7 70% The late feedback does not reflect the immediate feedback. 8 80 % The observation is not intended at teacher development. 9 90% The feedback is threatening if it is unsatisfactory. 9 90% Classroom observation does not fulfill my educational need 7 70 Classroom observation has no impact whether negative or positive. 2 20% Classroom observation partially fulfill my educational need 1 10% Discussion Obviously, there are no defects in the observation instrument. So, where is the problem? The result of the questionnaire provided to ten teachers revealed that the problem is in the observation process itself. The majority of the tutors (80%) have been observed two times per semester by the ASP whereas the remaining 20 % were observed three times by the ASP and the CAC (table 1). All the teachers (100%) expressed various levels of frustration and anxiety when they are observed. They assured that the observers themselves were a source of apprehension. Teachers added that none of the observers take an action to alleviate their anxiety. All the tutors (100%) expressed their feelings of dissatisfaction with the observation methods as no pre observation conference is conducted neither before the announced or the unannounced visits. This puts more stress on the side of the observees. Furthermore, 70% of the teachers mentioned that the way the observer enters and sits at the back of the cla ss ticking items on a checklist. This disrupts the stability of the classroom environment as the students perceive that he is observing them making them reluctant to answer and participate in the class effectively which in turn impact the execution of lesson. This is because the observer did not identify himself to the students as well as the purpose of being there. Moreover, he sits in the corner of the class and started to document his notes all the time. Accordingly, the students think that he is writing about them. Another significant point raised by 80 % of the teacher is the feedbacks given by the observers. They confirm that the immediate feedback provided is inconsistent with the late feedback received by the teachers. The striking issue was the perception of the 90% of the teachers for the session appraisal as a threat rather than developmental (Fig 3).Teachers feels intimidated and frightened by the entire supervisional process. This is because the models of observation we inherited are authoritarian and directive. All these factors combined their effects to increase teachers anxiety and dissatisfaction. When teachers asked to rate their level of satisfaction with the process of observation, 70% considered it unsatisfactory as it does not fulfill the educational needs of the teacher and did not enhance their teaching methods, 20% were neutral and 10% was fairly satisfied( Fig 4). This necessitates reconsideration of the overall observation process. Number of teachers Frequency of observations Percentage 8 2 80% 2 3 20% Table Frequency of observation Figure 3 Perception of classroom observation Figure 4 Satisfaction level Recommendations: Based on the findings of this Investigation, the investigator recommends certain points to enhance the process of the classroom observation. Having a pre-observation conference will guide the observers during the observation phase and will ease the teachers level of anxiety that result from the process in the part of the teachers. This will also assist the discussion that takes place in the post-observation conference. The professional teacher is one who is able to reflect critically on their own practice (Schon 1983, Wallace 1991). Accordingly the overall process will promote refl

Radio Shacks Termination of Employees Essay -- Corporate Communicatio

Radio Shack As the economy continues to be unstable companies, large and small, are making decisions to reduce their workforce. This is a daunting task that has to be handled delicately. When companies begin the process of reduction, even if the staff is aware, the communication must be honest, open and appropriate. If a company is a large retailer there is more at stake than just the current financial situation. The employees can become customers and advocates for the business. They can also become the customers of the competitors and communicate to others the bad experience. In 2006 Radio Shack was on a turnaround plan (O’Rourke, 2010). This plan included a reduction of workforce of about 400 employees. Employees were aware this was the plane, but were taken by surprise that when the â€Å"pink slip† came through as an email. Most employees received this at the same time and were given a limited amount of time to gather their belongings and say goodbye. This action cau sed a backlash of publicity. For Radio Shack to continue and regain trust of the employees and public they will need immediate training in communication standards to further avoid any other incidents. Secondly, they must reach out the employees that received the email and lastly work on a new mission statement and culture to match with where the company is heading. Communication training Understanding the audience is a very important piece to communication (O’Rourke, 2010).

Family Violence :: Domestic Violence Essays

Domestic abuse and child abuse have widespread social and emotional costs. Family violence affects all segments of the family. The impact of violence on childrens' lives appears to be far more substantial than the impact on adults lives(Family, Pg. 1). In most cases of family violence the family has conformed to a pattern in which the line of family violence started generations ago. This pattern must be broken before more children growup and live in a family that resorts to violence. But there are also children who live in loving families who do not resort to violence and as these children mature they start resorting to violence to help solve and deal with their problems. Studies show that physical punishment could cause aggression in children, but other studies show that even abusive parental violence does not always lead to an increase in children's aggression. Only by recognizing and addressing the multifactorial roots of violence in our society can we move closer to livi ng in peace. Violence within families often reflects behaviours learned by children from their parents. A theory is that violent behaviour is passed down from generation to generation through families (Cole & Flanagin, Pg. 2). The majority of Americans are subjected to corporal punishment at one point or another during their lifetime(Kandel, Pg. 4). Surveys suggested that almost all American parents used physical punishment at one point or another and the punishment was regared as an appropriate child rearing technique. Another survey also suggested that some psychologists belive physical punishment to be an effective and useful socialization tool(Kandel, Pg. 2). Aggression is commonly conceived as existing on a continuum, ranging from very severe parental aggression to much milder and normal parental aggression, such as use of corporal or physical punishment(Kandel, Pg. 1). A common concern is that parental use of physical punishment will lead to aggressive behaviour in children. There are three types of relationships between parents and their children, the first is a positive, linear one: some researchers have contended that any parental aggression may be positive and casually related to the development of antisocial aggression, the second group suggested that lack of physical punishment may contribute casually to the development of aggression and in the third group there was either too little or too much physical punishment that may increase the probability of aggressive behaviour in

Biography of Moses Essay -- Biographies Bio Religion Judaism

  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Main focus will be on Moses. He was the greatest prophet, leader, and teacher of Judaism. By focusing on Moses, I’ll incorporate the importance of certain passages that prove the Old Testament; and show how Moses’ role was significant and essential to the Hebrews. Moses 1400 B.C.E In a nutshell†¦ Moses was born in a very difficult time: Pharaoh had ordered that all male children born to Hebrew slaves should be drowned in the river (Exodus. 1:22). Moses’ mother hid him for three months, and when she could no longer hide him, she put him in an ark and placed it on the river where Pharaoh's daughter bathed (Ex. 2:2-3). Pharaoh's daughter found the child and had compassion for him (Exodus. 2:6). Although Egyptians raised Moses, the compassion he felt toward his people (the Hebrews) was so great that he could not bear to see them beaten by Pharaoh's taskmasters. One day, when Moses was about 40 years old, he saw an Egyptian beating a Hebrew slave, and he was so outraged that he struck and killed the Egyptian (Exodus. 2:11-12). Both the Hebrews and Pharaoh condemned him for this actions, and Moses was forced to flee from Egypt (Ex. 2:14-15). G-d appeared to Moses and chose him to lead the Hebrews out of Egyptian slavery and to the Promised Land, Israel (Ex. Chs. 3-4). With the help of his brother Aaron, Moses spoke to Pharaoh and triggered the plagues against Egypt (Ex. Chs. 4-12). He then led the people out of Egypt and across the sea to freedom, and brought them to Mount Sinai, where G-d gave the people the Torah; and the people accepted it (Ex. Chs. 12-24). G-d revealed the entire Torah to Moses. The Torah includes the first five books of the Bible (Genesis, Exodus, Leviticus, Numbers and Deuteronomy) that Moses wrote as G-d instructed him. It also includes all of the remaining prophecies that would later be written down in the remaining books of scripture. Furthermore, it contains the entire Oral Torah the oral tradition for interpreting the Torah, which would later be written down in the Talmud. Moses spent the rest of his life writing the first five books, essentially taking dictation of G-d. After Moses received instruction from G-d about the Law and how to interpret it, he came back down to the people. There he found the Hebrews idolizing a golden calf. This is a very significant story in the Bible. It show... ...nomy. According to some, Moses wrote the last few verses from a vision of the future, but according to others, the last few verses were added by Joshua after Moses’ death. Moses’ position as leader of Israel was not hereditary. His son, Gershom, did not inherit the leadership of Israel. Moses’ chosen successor was Joshua, son of Nun (Deut. 34:9). Moses was 120 years old at the time that he died (Deut. 34:7). That lifespan is considered to be ideal, and has become proverbial: one way to wish a person well in Jewish tradition is to say, "May you live to be 120!" As important as Moses was to the Children of Israel, it is always important to remember that Moses himself was not the deliverer or redeemer of Israel. It was G-d who redeemed Israel, not Moses. Moses was merely G-d's prophet, His spokesman. The traditional text of Passover does not even mention Moses’ name. In order to prevent people from falsely worshipping Moses, his grave was left unmarked (Deut. 34:6). Bibliography and Resources: †¢ Fields, Lanny B., Barber, Russell J., Riggs, Cheryl A.

Ð  good pÐ °rt of thÐ °t Ã'â€"s due to the brÐ °Ã'â€"n Ã'â€"njury Ã'â€"tself. Complex systems Ã'â€"n the brÐ °Ã'â€"n Ð °re Ã'â€"njured. The chemÃ'â€"cÐ °l bÐ °lÐ °nce Ã'â€"n the brÐ °Ã'â€"n Ã'â€"s upset. Ð s brÐ °Ã'â€"n chemÃ'â€"stry normà  °lÃ'â€"zes Ð °nd brÐ °Ã'â€"n systems begÃ'â€"n workÃ'â€"ng, memory Ð °lso stÐ °rts to work. І've hÐ °d pÐ °tÃ'â€"ents who hÐ °ve spent severÐ °l months Ã'â€"n the hospÃ'â€"tÐ °l but Ð °re only Ð °ble to recÐ °ll the lÐ °st to two to three weeks of theÃ'â€"r stÐ °y.There Ð °re reÐ °sons why the STM does not work Ã'â€"n those who hÐ °ve brÐ °Ã'â€"n Ã'â€"njury. The reÐ °son lÃ'â€"es Ã'â€"n the wÐ °y the brÐ °Ã'â€"n works. Ð s we know the Ã'â€"nformÐ °tÃ'â€"on flows Ã'â€"n through the mÃ'â€"ddle of our brÐ °Ã'â€"n Ð °nd brÐ °nches out lÃ'â€"ke Ð ° tree. Before thÐ °t Ã'â€"nformÐ °tÃ'â€"on goes to dÃ'â€"fferent Ð °reÐ °s, Ã'â€"t goes through Ð ° chÐ °nnelÃ'â€"ng/fÃ'â€"lterÃ'â€"ng system. Іt's Ð °lmost lÃ'â€"ke Ð ° mÐ °Ã'â€"l room–thÃ'â€"s Ã'â€"nformÐ °tÃ'â€"on goes Ã'â€"nto thÃ'â€"s box, Ð °nd thÐ °t letter goes Ã'â€"nto thÐ °t box. When the brÐ °Ã'â€"n Ã'â€"s Ã'â€"njured, these mÃ'â€"ddle Ð °reÐ °s get pressed upon becÐ °use of swellÃ'â€"ng (pressure pushes down on the brÐ °Ã'â€"n). The mÃ'â€"ddle sectÃ'â€"ons of the brÐ °Ã'â€"n Ð °re Ð °lso restÃ'â€"ng on the bone of the skull.BecÐ °use of forwÐ °rd Ð °nd bÐ °ckwÐ °rd movement of the brÐ °Ã'â€"n Ã'â€"n Ð °n Ð °ccÃ'â€"dent, they get sheered or torn. Ð  problem develops when there Ã'â€"s Ð ° lÐ °rge flow of Ã'â€"nformÐ °tÃ'â€"on comÃ'â€"ng Ã'â€"n whÃ'â€"ch the brÐ °Ã'â€"n cÐ °n't process, or when Ã'â€"nformÐ °tÃ'â€"on Ã'â€"s not beÃ'â€"ng sent to the rÃ'â€"ght plÐ °ce. So the mÐ °Ã'â€"l room of the brÐ °Ã'â€"n Ã'â€"s not doÃ'â€"ng Ã'â€"ts job. There Ã'â€"s Ð °lso Ð ° second type of memory problem. Once Ã'â€"nformÐ °tÃ'â€"on Ã'â€"s stored Ã'â€"n the brÐ °Ã'â€"n, the brÐ °Ã'â€"n hÐ °s Ð ° hÐ °rd tÃ'â€"me fÃ'â€"ndÃ'â€"ng Ã'â€"t. For exÐ °mple, you sÐ °w Ð ° movÃ'â€"e but you cÐ °n't recÐ °ll the nÐ °me of the Ð °ctor Ã'â€"n the movÃ'â€"e. You cÐ °n vÃ'â€"suÐ °lÃ'â€"ze who the Ð °ctor Ã'â€"s, but cÐ °n't come up wÃ'â €"th hÃ'â€"s nÐ °me.People typÃ'â€"cÐ °lly descrÃ'â€"be Ð ° â€Å"tÃ'â€"p of the tongue† type of thÃ'â€"ng–â€Å"І know whÐ °t І wÐ °nt to sÐ °y but І just cÐ °n't get Ã'â€"t out†. Іt’s Ð °lmost Ð °s Ã'â€"f the brÐ °Ã'â€"n Ã'â€"s sÐ °yÃ'â€"ng, â€Å"seÐ °rchÃ'â€"ng, seÐ °rchÃ'â€"ng† Ð °nd not fÃ'â€"ndÃ'â€"ng. SeverÐ °l mÃ'â€"nutes lÐ °ter, Ã'â€"t just comes to you. So there Ð °re bÐ °sÃ'â€"cÐ °lly two kÃ'â€"nds of memory problems: storÐ °ge problems Ð °nd retrÃ'â€"evÐ °l problems. Іn conclusÃ'â€"on І would lÃ'â€"ke to sÐ °y thÐ °t Ã'â€"t Ã'â€"s very Ã'â€"mportÐ °nt to Ã'â€"mprove the memory Ð °nd mÐ °ke regulÐ °r exercÃ'â€"se whÃ'â€"ch wÃ'â€"ll contrÃ'â€"bute to thÃ'â€"s process.
