Observing The Setup Of The Classroom - 920 Words
On December 4, 2015 we observed the class for which we developed this response plan. Our main objective was to observe the setup of the classroom as well as the different instructional tools the teacher used to enhance her teaching. In addition, we wanted to see what strategies the teacher implemented to help the ELL and autistic students and see if they were similar to what had in our plan. Upon arriving, we observed that the teacher, Ms. Schmitt, had a large classroom with enough space for groups of students to work together. At the front of the classroom, was the teacherââ¬â¢s desk with a smart board behind it. Several other white boards filled the rest of the wall space. The board on the left was used mostly for instructional purposes while the two on the right were filled with vocabulary and important announcements such as upcoming tests dates. The extra space allowed the teacher to interact with all the students individually. Also, we noted that the teacher had placed the E LL students near the front of the room where she could easily help them or ask them to help each other. The students on the Autism spectrum where located near the back of the classroom where they had more room to work with their aids. However, none of these students were completely isolated from the teacher or rest of the class. Rather all of the students were able to easily interact with one another. At the beginning of class the teacher had the students review material from the previous dayââ¬â¢s lessonShow MoreRelatedThe Theory Of Teacher Collaboration1326 Words à |à 6 Pagesgoal and shared understanding are important aspects of teacher collaboration.

Parental rights duties and obligations are outlined. Provisions are made regarding fostering, adoption, child minding and day care. When making welfare decisions, the courts are obligated to take into consideration the Childââ¬â¢s wishes and feelings. Law amendments are made, regarding Community, Voluntary and Childrenââ¬â¢s homes and voluntary organisations. Every TA should know who the safeguarding officer/s are in the school and should know the appropriate ways to communicate with them. There should be knowledge of safeguarding policies and procedures or at least access to copies of the above.

All organisations must refer to PoCA list when checking prospective employees. Made it an offence to employ anyone on the PoCA list, even if already employed. A Teaching assistant has a duty to disclose any information regarding any other employees or prospective employees to superiors. 2003 Hidden Harm Focused on children of parents or guardians with drug/alcohol addictions that cause serious negative consequences for themselves and their families. Teaching Assistants should be familiar or at least have access to clear guidance on drug related instances. TAââ¬â¢s have a responsibility to make sure that they, themselves, are adequately trained in recognising signs and possible indications of drug related neglect and general safeguarding. It is the role of the TA to assist in providing a positive school experience. This, in turn, will equip the child with the resilience to cope with adverse life circumstances. 2003 Every Child Matters Green Paper ââ¬â published with the report into the death of Victoria Climbe. Focus on supporting families and carers. Ensures that interventions take place before crisis point and also that children do not fall through the net. Identifies underlying problems associated with the Victoria Climbe report. Ensures people working with children are valued and supported. ââ¬Å"Every Child Matters acknowledges that children and young people cannot learn effectively if they do not feel safe, healthy or happy, and that learning and well-being go hand in hand. â⬠2007 According to the ECM standards, every member of support staff should be trained and supported, utilized and encouraged to be successful in their employment. Therefore, TAââ¬â¢s should have an efficient induction, continuous professional development, regular appraisals and be able to seek on-going support. TAââ¬â¢s have a tendency to work closely with children in a group or 1:1 capacity. This is likely to provide a closer working relationship with the children, allowing observations of behaviour in class and a greater knowledge of background, culture and family life. It is also the TAââ¬â¢s responsibility to know the referral process according to the Schoolââ¬â¢s Safeguarding Policy, if there is a suspicion of a safeguarding issue. 2004 The Children Act Nominated Childrenââ¬â¢s Commissioner. Orders a provision of services regarding private fostering, Child minding/day care. Updated punishment legislation: Offence to hit a Child if it causes mental harm or leaves a mark on the skin. Retracts section in 1989 Children Act regarding reasonable chastisement. Specific provision for disabled children. Highlights the need for support staff to train regarding the identification of possible signs of abuse. It is also necessary to have the ability to know when a given account of how a physical injury was sustained does not tally with the actual injury. There is also a role for support staff to assist in teaching pupils to protect themselves, to a certain degree, against abuse or bullying. Working Together to Safeguard Children 2006 Agencies and organisations should work together, sharing information in order to provide effective services to children, adults and their Carers. The above agencies and organisations have a duty of care and responsibility for safeguarding and promoting the welfare of children. TAââ¬â¢s should be aware of potential indications of abuse. (Stated under ââ¬ËProtectionââ¬â¢) Be vigilant regarding the risks that abusers or potential abusers cause to children. Share any information that may be useful in assessments made regarding the childââ¬â¢s needs and circumstances. If asked, it is useful for the TA to regularly take part in reviews and the making of specific plans. If it is possible to work with the childââ¬â¢s parents, there is a need for good communication skills, using unbiased language and neutrality. Discuss the steps you would take if you had concerns for the safety and wellbeing of a child. When dealing with suspected physical, sexual, emotional abuse or neglect it is important for every staff member, including support staff, to be aware of how to manage the initial contact with the child, if there is any, and then the appropriate reporting procedure. All schools will have a Safeguarding Policy that should be made easily available for every member of staff. According to the policy used for this exercise, there are five easy steps to remember. Receive If a child needs to talk it is necessary for he/she to have my immediate attention. If this opportunity is not taken the child may change their mind. I would need to listen intently and quietly, with comfort and sympathy, allowing silences where necessary. It is important that I show no denial, shock or disbelief and that the child feels as little responsibility as possible. Unfortunately, children that experience abuse often grow up feeling responsible and blaming themselves for the abuse (2009) More importantly, I would need to take this issue very seriously, even if I have no proof of validity. Reassure It is vital that I should remain calm and composed and that I remain neutral, making no judgements but showing some empathy. It is crucial that I do not make any promises of secrecy to the child, but reassurance that only those that need to know will be told needs to be given. It is important that the child knows that they have made the right decision in telling you. React It is important for me to refrain from overreaction. I am trying to establish whether this is a matter that needs to be referred or not. Overreaction may cause the child distress. Essentially, I should avoid asking leading questions, and keep them open. Also, I should avoid asking too many questions as this would be construed as interrogation, and it is not my place to conduct an interrogation. I am required to remain neutral and refrain from criticising the possible abuser as the child undoubtedly holds affection for them. At this point I must try and explain what I amà going to do next. Record If feasible, I would need to write down and record the time, date and a brief account of the discussion, making sure that it is not my interpretation but an accurate account of what the child expressed to me. Also, it is necessary to document any noticeable non-verbal behaviour. The Safeguarding policy held by the school will direct me to official forms that need to be filled in, so, at this stage, I would fill in a report form. Report Inform the designated teacher/safeguarding officer as soon as possible. There may not have been an initial contact with the child and it may be that there is more of a suspicion of abuse or neglect. In this case, there would be a need for tactful, unobtrusive questions. The TA has to recognise if a child does not want to talk then the matter must not be pursued. Alternatively, it may be useful to discuss the situation with the designated teacher/safeguarding officer before making an official referral. Evaluate the effects of domestic abuse on children. What impact could this have on children within the school setting? According to domesticviolence. org, domestic violence or abuse is defined as the use of behaviours by one person in a relationship with the sole purpose of controlling the other. Partners do not have to be married for domestic abuse to occur. Department of Health in 2002, states that; At least 750,000 children a year witness domestic violence. Nearly three quarters of children on the at risk register live in households where domestic violence occurs Cited by Womenââ¬â¢s Aid, 2014. DoH also believes that to witness domestic abuse is emotional abuse in itself. This may possibly be through the witness of a physical injury to an adult or sexual abuse of an adult or even being caught in the middle of a violent dispute between two adults themselves. Frank, Putnam and Teicher, 1994, found that chronically high levels of adrenalin can kill neurons in the brain areas crucial for thinking and memory. In the instance of a child witnessing domestic abuse, the levels of adrenalin would be high enough to arrest the growth of the left hemisphere of the brain and thereby hampering the development of language and logic. There would also be an increase in the bodyââ¬â¢s antibodies which would significantly weaken the immune system. Children may respond to the witnessing of domestic abuse very differently. These are some of the effects described in a briefing by the Royal College of Psychiatrists (2004): They may become anxious or depressed, causing segregation from friends. They may have difficulty sleeping, effecting their focus and ability to concentrate. They have nightmares or flashbacks, leading to a lack of quality sleep. They can be easily startled, triggering the ââ¬Ëfight or flightââ¬â¢ reaction which in turn produces adrenalin and increasing anxiety. They may complain of physical symptoms such as tummy aches, associated with anxiety. They may start to wet their bed, instigating low self-esteem and a domino effect to a lot of other effects. They may have temper tantrums, possibly caused by confusion and the inability to understand the situation. They may behave as though they are much younger than they are. They may become aggressive or they may internalise their distress and withdraw from other people. Jaffe, Wilson and Wolfe (1986) suggest that childrens exposure to adult domestic violence may generate attitudes justifying their own use of violence. Cited in Edleson, 1997. They may have a lowered sense of self-worth, causing a withdrawal and failure to thrive in the classroom. They may have an eating disorder, or could well reduce their eating to a very low level. If the domestic abuse is not discovered, or investigated, then a child witnessing the act would inevitably display one or more of the above regularly. They would be at a higher risk of irreversible damage to cognitive, behavioural and social areas of their lives and there would be a definite failure to thrive.

Study, Learn, and Read
Study, Learn, and Read Study, Learn, and Read Study, Learn, and Read By Maeve Maddox Some ESL speakers have trouble with these verbs. To study is to apply the mind to the acquisition of knowledge. Books are the first avenue that comes to mind, but as the object of study is the acquisition of knowledge, other means include observation and experiment. Play is a form of study for children. Although the word learn is closely associated with study, the following sentences have completely different meanings: I am studying German. I am learning German. Many a student studies a subject in school without learning it. To read has several meanings. The most common is ââ¬Å"to scan written or printed words and get meaning from them.â⬠One noteworthy usage difference between British and American English is the use of read in reference to postsecondary education. In the U.S., students go to the university ââ¬Å"to study historyâ⬠or some other subject; in England, they go to university ââ¬Å"to read history.â⬠The idiom ââ¬Å"to read up onâ⬠means ââ¬Å"to study.â⬠For example, ââ¬Å"Before you travel to India, you may want to read up a little on the culture.â⬠Idioms with read: to read between the lines: to draw conclusions not apparent from surface appearances. ââ¬Å"She tells them that she cares for them, but when she turned down their last three dinner invitations, I could read between the lines.â⬠read my lips! Ordinarily, this expression is used to emphasize a speakerââ¬â¢s sincerity and resolve: ââ¬Å"Listen carefully!â⬠ââ¬Å"Pay close attention!â⬠ââ¬Å"Take my word for it!â⬠In 1988, the phrase became closely associated with G. H. W. Bush, who said, ââ¬Å"Read my lips: No new Taxes!â⬠when accepting the presidential nomination. Because Bush did raise taxes during his presidency, political writers often use the phrase ironically. to read someone like a book: to understand a personââ¬â¢s character and thoughts by studying outward signs. to read a personââ¬â¢s mind: to guess what a person is thinking or intending to do. to read the Riot Act: The phrase originated in reference to an 18th century Act passed by the British Parliament following several serious riots. The Act authorized local officials to disperse any gathering of more than 12 people who were unlawfully, riotously, and tumultuously assembled together. An official would confront the group and read the part of the act that spelled out the consequences for refusing to obey. Nowadays the expression is used by adults in reference to noisy children: ââ¬Å"Sounds like theyââ¬â¢re getting pretty wild in there; youââ¬â¢d better go read them the Riot Act.â⬠Idioms with learn: to learn by heart: to memorize learn by rote: to learn by means of repetition, the way one learns the alphabet, the multiplication tables, and scientific phyla. A learning curve is psychological jargon that has found a place in the general vocabulary. It means ââ¬Å"the rate of a personââ¬â¢s progress in learning a new skill.â⬠The expression derives from is a curve on a graph illustrating the rate of learning by a lab subject. Modern usage distinguishes between learn and teach, but in Shakespeareââ¬â¢s time, learn was used in the sense of ââ¬Å"teachâ⬠: The red plague rid you for learning me your language! Caliban, The Tempest I:ii (1611) This use survives in some dialects, but not in standard usage. Fewer idioms with study come to mind: study a face: to look closely at a face, as if to memorize its features. study the options: to consider possible solutions to a problem or course of action. be in a brown study: ââ¬Å"A state of mental abstraction or musing; gloomy meditation.

Explain what's meant by Transaction Cost Economising. Also analyse Essay
Explain what's meant by Transaction Cost Economising. Also analyse between contributions made by Coase & Williamson - Essay Example For example, the searching cost (the energy and effort taken to find out the good), the cost of traveling for availing it, waiting time to get it and even the effort of paying it self are the costs incurred above and beyond the market price of that particular commodity. This ââ¬Ëaboveââ¬â¢ and ââ¬Ëbeyondââ¬â¢ market price is the transaction cost. Now days, transaction cost is significant in each and every potential transaction. Transaction Cost Economics and Economizing The Transaction Cost Economics is the approach of analyzing the economic organization which considers transaction as the basic unit of analysis and it stresses that economizing the transaction cost is the central part of the analysis in the study of economic organizations. The cost of factors of production (resource inputs) , ie, land ,labor and capital, should be called as resource cost and for the better production, the resource cost should be the minimum. For enhancing the production and productivity, t he co-operation and investments in specialization are highly desirable. Co-operation between economic actors and investments in specialization are the major components of productivity enhancement. For achieving this co-operation and investment specialization, cost arises due to the inclination of self interested owners of inputs to shirk the commitments. The costs that incurred for the minimizing the shirking include: i) Searching cost incurred to identify the owners of the inputs (when, where and what type of the required good is available in the market with minimum price) ii) Negotiating or bargaining cost is the cost incurred for implanting an acceptable agreement between these two parties. In stock or asset market, it is the distance between ââ¬Ëbid and askââ¬â¢. It also includes the costs of any incentive given to minimize the shirking. iii) Monitoring cost and iv) Enforcement cost In spite of all these costs, residual loss from shirking may exist because of the inability of the above mechanisms to bring the shirking to zero in a complex and uncertain economy. Hence, the costs incurred to minimize the shirking plus the residual loss from shirking together constitute ââ¬Ëtransaction costââ¬â¢(Hill, 1995). Contributions of Coase and Williams to the theory of Transaction Cost Economizing The origin of the theory of transaction cost economizing can be traced to a contributions of John R Common, 1932, Ronald H Coase 1937 and 1960, Friedrich Hayek, 1945, Herbert Simon, 1951, Chester Barnard, 1938, Philip Selznick , 1949 and Alfred Chandler, 1962. (Williamson, 1981). Among this series, the works of Ronald H Coase and Oliver Williamson are the real milestones. Coase laid the foundations of the Transaction Cost Approach while Williamson built a strong structure for the analysis. Both of them provide suitable and strong theoretical contributions to Transaction Cost Economics under the broad framework of Institutional Economics and they focus on how tran sactions have to be organized in order to economize the transactions. While describing the applications of transactional economics, it is assumed that different dimensions of transactions have to be identified and the alternative governance structure has to be described. Economizing of transactions can be achieved by discriminatory assignment of transactions to governance structures. The application of transaction cost approach lies both in the demarcation of efficient boundaries between firms and markets and in the governance

Global Environmental Change Assignment Example | Topics and Well Written Essays - 3000 words
Global Environmental Change - Assignment Example (Tollefson, 2009, p. 29) The arctic holds an important place in the debatable issue of maintaining life on earth in a sustainable way. However, this discussion centres on the Arctic region itself and more precisely on depleting population of the arctic Polar Bears rather than the chain effect of the susceptible artic on the rest of the world. The last hundred years have witnessed an increase in global temperature by 0.6 degree centigrade. (Jenssen, 2006, p. 78) Moreover from 1976 the rate is even higher and unmatchable by any time encompassing past thousand years. The effect of such rise in temperature is most visible through the extent of ice melting in the high and mid altitude area. In less than fifty years the snow has decreased by 10%. (Jenssen, 2006, p. 78) For the survival of a species, the survival of its habitat and food source is of utmost importance. With the rise in global temperature the extent of ice will decline in the Arctic and so will its duration of frozen state, resulting in less area for the seals to stay and breed. Seals are the most important food source of the polar bear; so any effect on their population will directly reduce the food basket of the polar bears. It has also been observed that for large mammals any change in global temperature affects the juvenile survival rate. From this point of v iew both the seal and the bear are equally exposed to risk. Therefore the bear suffers from two sides - reduced present and future food source and reduced juvenile survival rate. Again the polar bear hunts on ground (solid ice). Any reduction of ice extent will leave the bear with smaller ground to catch seals. (Jenssen, 2006, p. 78) In front of global climatic change the arctic ice plate has also undergone changes in terms of thickness and has become fractured in many places. Furthermore the ocean now freezes in later part of the year and all these in a cumulative way are depleting the habitat of polar bear. (Oââ¬â¢Neill et al, 2008, p. 1650).
