Problems of Student Achievement in Education
Problems of Student Achievement in Education Student achievement is a subject that attracts great concern from parents, teachers, administrators, and even policy makers. Despite the fact that teachers are mostly the victims of blame after poor academic performance, there are many factors that may make students perform poorly in their exams. Some of these factors can be controlled by teachers, while others are well beyond their control.Advertising We will write a custom essay sample on Problems of Student Achievement in Education specifically for you for only $16.05 $11/page Learn More The main challenge in combating poor student performance in schools has been the identification of the aforementioned factors. School administrators should, therefore, ensure that they do all they can to establish the reason for non-performance of students. This paper is an exploration of some of the main cultural, ethnic, and socioeconomic factors that influence student performance. There is a close relationship between the backgrounds of students and their performance. Some of the domestic problems that affect student performance include food insecurity, domestic violence and parents who abuse drugs (Andrews, 2005).Students also perform poorly due to health-related problems. These include sight problems, poor hearing ability, and poor sleeping patterns (Andrews, 2005). The latter makes students unable to concentrate during lessons leading to poor performance. Combining education with work has also contributed to poor student performance. This is normally evident in mid-age students. The pressure under which such students operate makes them unable to dedicate enough time to studies, and thus they end up performing poorly in their exams (Thomas, 2003). The students may also fail to see the meaning of education because they may give too much value to the money they make. This may make them commit more time to their jobs than the time they commit for studies. Also among the factors influencing student performance is the fact that students may form ethnic groups in schools (Jacobson, 2003). These groups are usually formed by students who belong to a given ethnic community, and they negatively affect student performance since the activities of the groups tend to be non-academic. Other students may form peer groups which may negatively influence their members leading to poor academic performance (Andrews, 2005). Given the devastating effect that the aforementioned issues have had on student performance, and the fact that attempts to curb them have been largely unsuccessful, there is need for a nuanced approach in dealing with them. Parents should ensure that they provide an environment conducive for student-growth.Advertising Looking for essay on education? Let's see if we can help you!

Teachers, on the other hand, shou ld ensure that they understand the special problems of their students, especially problems related to health, and come up with counter-measures for ensuring that students get the best out of class work. There is also the need for teachers and school administrators to monitor students closely in order to ensure that their activities within the school are focused on academics (Thomas, 2003). Peer groups, and ethnic groups, should be strictly discourages because they have adverse effects on student performance. This will help to reduce influence within the school, and discourage laxity. Administrators should also ensure that they address the issue of working students. The administration in schools should develop appropriate policies that will ensure working students get their best out of their education. Finally, students should be given periodic and holistic counsel to ensure that they do their best to get good grades. Reference List Andrews, T. (2005).

Calvin Taylors Model of Critical and Creative Thinking
Calvin Taylor's Model of Critical and Creative Thinking The Calvin Taylor creative thinking model describes the talent areas as productive thinking, communication, planning, decision making, and forecasting. This model is best known as Talents Unlimited, a program of the National Diffusion Network of the U.S. Department of Education. The Taylor model incorporates both the critical and creative elements of thinking. Rather than a taxonomy, this is a thinking skills model that describes the essential elements of thinking, beginning with the academic talent and then incorporating the other talent areas, as described in more detail below. Productive Thinking Productivity promotes creative thinking in the Calvin Taylor model. It suggests critical and creative thinking of many ideas, varied ideas, unusual ideas, and adding to those ideas. Communication Communication has six elements which include: Give many, varied, single words to describe something.Give many, varied, single words to describe feelings.Think of many, varied things that are like another thing in a special way.Let others know that you understand how they feel.Make a network of ideas using many, varied and complete thoughts.Tell your feelings and needs without using words. Planning Planning requires that students learn to tell what they are going to plan: The materials that they will need.The steps that they will need to accomplish the task.The problems that might occur. Decision Making Decision making teaches the student to: Think of the many, varied things that could be done.Think more carefully about each alternative.Choose one alternative that they think is best.Give many, varied reasons for the choice. Forecasting Forecasting is the last of the five talents and requires students to make many, varied predictions about a situation, examining cause and effect relationships. Every element of the Calvin Taylor model is used when a child invents.

Factors Influencing Health Seeking Behaviors of African Americans Research Paper
Factors Influencing Health Seeking Behaviors of African Americans experiencing Stroke Symptoms A Systematic Review - Research Paper Example According to Wiley (2009), only 56.3% of African American respondents identified brain as the organ where stroke occurs. Among stroke symptoms, hemiparesis, speech disturbance, headache and blurred vision were the best recognized. Primary risk factors for stroke were correctly identified and included hypertension, family history of stroke, obesity, smoking and cocaine abuse. From the perspective on study results, Wiley et al (2009) found significant deficiencies in stroke literacy among African American study sample. Because of poor stroke literacy in Wiley's et al study (2009), participants were not likely to activate EMS. Consequently, poor literacy on stroke symptoms among African American population jeopardizes the effectiveness of early prevention therapy. King et al (2001) in their study aimed to determine whether African American individuals suffered from stroke (n=103) presented for treatment within the first 3 hours, a critical period needed for effective treatment with recombinant tissue plasminogen activator (rt-PA). Through Stroke Survey Tool, King et al (2001) determined that an average time needed for African American victims to present for treatment constituted 24.68 hours.

COFFEE DIRECT UK SOCIAL ENTERPRISE Essay Example | Topics and Well Written Essays - 2750 words
COFFEE DIRECT UK SOCIAL ENTERPRISE - Essay Example Due to the factors like technological advancements, developments in the communication process and globalisation, the terms of the trade are fast changing. The traditional beliefs and the conventional ways are being replaced by newer methodologies and tricks. The massive competition in the industry has helped the processes to become sharper and efficient. Traditionally, it was all about those companies that would have sold coffee powder and the coffees would specifically be prepared at home. But with time, the concept changed and new shops and organisations came up that claimed themselves to be professionally ran in order to sale various preparations of the celebrated drink. Coffee Direct is a front line organisation in that respect and claims itself to stock comprehensive selection of coffees. Established in 1990, Coffee Direct has been primarily a family run business. The group stocks wide range of coffees and teas and take pleasure to supply those to cafes, hotels, offices and also to home. The organisation also deals in the coffee machines all across the United Kingdom. Not only, it supplies but also it installs as well as commissions along with the add-on services like testing and maintenance of such machines. The Coffee Direct also provide free on-site training on the various of arts of coffee as it believe that without the knowledge of operating such machines, there is no point for the buyers to possess a high performance device. The training that the company provides is quite elaborate and includes the basic procedures of extracting the coffee in the proper and scientific way and also the organisation provides training on the various preparations of coffee like that of lattes, cappuccinos and various forms of espresso. The company makes it a point to carry out all the illustrations through adequately trained engineers (Coffee Direct, n.d.). The company acknowledges the fact that the two driving forces behind

Antisocial Behaviour Essay Example for Free
Antisocial Behaviour Essay In Britain antisocial behaviour between young people is a widely argued subject in the British media. More and more Brits at the age 13-18 are dropping out of school or work-based training and refuse to return. These young people are more than likely to face criminal action possibly leading to a fine or community sentence. But when we are talking about the term ââ¬Å"Anti-social Behaviourâ⬠, then we need to know what it exactly means. The British ââ¬Å"crime disorder actâ⬠of 1998 describes the term n anti-social manner, that is to say, in a manner that caused or was likely to cause harassment, alarm or distress to one or more persons So to simplify, Antisocial behaviour is when a person is forced by his or hers environment to cause harassment to one-self or the persons surroundings, and as far as I understand the subject antisocial behaviour does not have to be of criminal nature, but it is more than likely to be so. In 2007 the percentage of 16 to 17-year-olds not in education, employment or training was 9 percent. It is exactly these young people who are the targets for becoming antisocial. So how do you make sure that these unfortunate teenagers donââ¬â¢t end in this so unfortunate situation and is it possible to force the teenagers to behave in a more civilised way? There are actually many suggestions for a solution to this nationwide problem. Some of them are quit controversial and are more likely to stop antisocial teenagers doing crime, than to prevent teenagers to not at all become antisocial. One of these alternative solutions is the ââ¬Å"Mosquitoâ⬠which is a sonic device that gives out a piercing noise audible only to teenagers and people in there early twenties. This device has been installed as a ââ¬Å"yobâ⬠(slang for an antisocial person) deterrent at nearly 3,000 locations such as grocers and shopping malls across Great Britain. This Mosquito is a camouflaged speaker box not larger than shoebox and it sends out a pulse at 18 kilohertz which in the last end will give the young people acting antisocial in front of the store a terrible headache so they quickly leave the store. This method of fighting antisocial behaviour among teens has been shown very effective. In some stores in the UK crime outside the stores had dropped by 83 % since the device was installed. The device has actually earned so much respect among shopkeepers and government officials that some are considering that the Mosquito should be obligatory by law in most public places by night. So it is quite obvious to see all the positive aspects but not all are so enthusiastic. Chief constables in Britain say they are scared the Mosquito is going to infringe human rights. Authorities say that the device is indiscriminating and that people should consider the effects on the young people, because not all young people are antisocial yobs. So you can see that the meanings about the Mosquito vary quite a lot. The device is very effective against the teens that already are in the antisocial environment but the device is not at all preventive. So what could be done if you the British teenagers to not even think about becoming antisocial. The British former PM Tony Blair wants to force errant schoolchildren back to school by using dedicated truancy officers which will be deployed in the 200 schools with biggest yob and truancy problems. This plan spans over using more than ? 70m to stamp out antisocial behaviour, as well as 24,000 community support officers will also be conducting these truancy sweeps so they can force the teens back to school. The plan does also include tougher punishments to the yobs when they get caught. This is of course a very controversial method to tackle antisocial behaviour but it could be showing really effective because it is preventive and helps the teenagers in trouble before they become antisocial yobs. But of course as mentioned by opponents of the plan, the plan is so ambitious and expensive that it more looks like ââ¬Å"a mish-mash of gimmick and spinâ⬠than an actual plan, which within realistic measures would be preventive without costing the country enormous amounts of money and labour. So here we have two very different plans which in two very different ways will deal with two very important parts of the subject antisocial behaviour among British teens. I do not think that there is any exactly solution to this very important problem in British cities, small towns and schools but of course the Mosquito has already proven its worth in more than 3,000 locations with success and has made it safer for those people being harassed by the yobs in the public. But unfortunately the Mosquito does not help educating the teens; it just makes the yobs find an other place for them to be at. The most important factor in this case is that you need to stop the antisocial behaviour in its process and not when it already has affected the young teenagers. So perhaps Tony Blairââ¬â¢s plan is the right way to do it, though I personally believe that the plan is way too focussed on hard punishment than in are pedagogical way. I donââ¬â¢t believe that tough punishment is the way of teaching youngsters today.

Kate Chopins novella, The Awakening Essay -- English Literature
Kate Chopin's novella, The Awakening In Kate Chopin's novella, The Awakening, the reader is introduced into a society that is strictly male-dominated where women fill in the stereotypical role of watching the children, cooking, cleaning and keeping up appearances. Writers often highlight the values of a certain society by introducing a character who is alienated from their culture by a trait such as gender, race or creed. In Chopin's Awakening, the reader meets Edna Pontellier, a married woman who attempts to overcome her "fate", to avoid the stereotypical role of a woman in her era, and in doing so she reveals the surrounding society's assumption and moral values about women of Edna's time. Edna helps to reveal the assumptions of her society. The people surrounding her each day, particularly women, assume their roles as "housewives"; while the men are free to leave the house, go out at night, gamble, drink and work. Edna surprises her associates when she takes up painting, which represents a working job and independence for Edna. Leonce does not appreciate this. The reader sees how he assumes what she should be doing from this quote on page 57: "Mr.Pontellier had been a rather courteous husband so long as he met a certain tacit submissiveness in his wife. But her new and unexpected line of conduct completely bewildered him. ... Then her absolute disregard for her duties as a wife angered him." Leonce says himself, "It seems to me the utmost folly for a woman at the head of a household, and the mother of children, to spend in an atelier [meaning a studio for painting] days which would be better employed contriving for the comfort of her family." This quote is rather symbolic as it uses the word "emplo... ...men surrounding her succumb to in life. By defying these "laws" Edna makes clear the morals that all the other women value; the satisfaction of their husband, the acceptance of society, and the conformity to stereotypical roles of a woman. In The Awakening, Edna is used as a tool to emphasize the surrounding society's assumptions of a woman and the morals that they value. Often, a character is set apart from their culture for this sole purpose, to stress a point the author wants to make. In this case, Chopin wants to show the reader how male dominated society has been, how quickly women succumb to their "roles", and how easily people can be shaped to consider a different and all too meaningless set of morals. Edna is strategically alienated in the novella so as the reader can discover society's assumptions and moral values of the era and up until today.

Foreign Players in English Football
On 30 December 2009, the Barclays Premier League football match between Arsenal and Portsmouth made English football history as the first match not to include any British players. Arsenalââ¬â¢s team of multi-million pound foreign stars won the game comfortably, 4-1; some would argue this is all that matters, but those who are passionate about football ââ¬â the real connoisseurs of the English game ââ¬â will recognize a deep underlying issue. Modern day football is unrecognizable compared to what has preceded it.In times past, teams were fashioned by nurturing young home-grown talent and bolstering the squad with a few lads from Scotland and Ireland. Now the common consensus is that to achieve any success it is necessary to catch the attention of an exceedingly wealthy oil tycoon who will buy the club and proceed to spend ? 200 million a year on overpriced talent from the four corners of the world. This ethos is destroying British football. For example in the Premier League there are 337 registered foreign players representing a total of 66 different countries.That equates to an average of 17 foreign players per squad; the averages in Italy, France and Spain are all around 10. On the first day of the inaugural Premier League season in 1992 just 22 non-British players started; on the first day of this season 124 started. It isnââ¬â¢t right that success should be based on finance, is it? In 2004 Russian billionaire Roman Abramovich bought Chelsea F. C. , a team which hadnââ¬â¢t won the league since 1954. He splashed an extravagant amount of money on the creme de la creme of foreign talent from around the globe.Three seasons later they experienced unprecedented success which, would never have happened without the cash injection. However, it was all achieved with just three regularly playing British players, who only made the squad because they were exceptional talents which money could not replace. This set a new benchmark for all the top teams in the land, making a clear statement that if they wanted to match Chelseaââ¬â¢s success they would have to match Chelseaââ¬â¢s spending and sacrifice their home-grown players or risk being left behind.In 1995 the British transfer record was ? 7,000,000; by 2006 the record had sharply risen to ? 30,800,000, and player wages were spiralling out of control. It is true that this has lead to stronger squads, and the Premier League being viewed as the strongest league in the World, with consistent success in Europe, but can it be right to sacrifice our own players for this success? I think not. Journalists, pundits and just about every football fan in England have formed their own theories concerning Englandââ¬â¢s miserable failure at the 2010 World Cup in South Africa.Many causes have been suggested, yet to me the reason is obvious. If one analyses the teams which were most successful in South Africa, a definite trend appears. Spain won the World Cup this year. Many argue that the y reached the final against Holland mainly because 77. 1% of footballers in their domestic league are qualified to play for the national team, a direct result of home-grown players being given the opportunity in their clubs' first teams. In the Premier League fewer than 40% of players are English. Jose Luis Astiazaran, president of the Spanish Football League, said. Our strategy is to work very hard with young home-grown players and to try to have a mix between them and experienced playersâ⬠¦ we invest moreà and more in young Spanish players than in young foreign players. England hasà many times taken young players from outsideâ⬠¦ these kinds of players are not English. This is one of the most important differences between Spain and England. We invest inà young Spanish playersâ⬠¦ maybe this is why at the moment you are not creating young English players. â⬠One view is that foreign players benefit the English players, who apparently perform better alongside th e Worldââ¬â¢s best. I think ââ¬â donââ¬â¢t you? that if more money, time, and attention were put into cultivating the abundance of young English talent, the English players themselves would be the worldââ¬â¢s best. The Premier League have recognised this, and this year the F. A. implemented new squad rules controlling the number of foreign players in each squad. This is a start towards reducing the amount of foreign players in the league, but the rules are too loose and easy to circumvent. Foreign players can be bought in from a young age and developed in the academies; this means the young Englishmen still donââ¬â¢t get the attention they crave in order to advance their careers.In my opinion the influx of foreign players in England is the single most detrimental factor in the game, leading to over-inflated transfer fees, increase in ticket prices, under development of home-grown players and ultimately the destruction of the national team. The Premier League must rev iew its policies, and clubs must invest in their academies or English national football will continue to deteriorate well into the future, and so many young aspiring footballers will be cast aside, and I for one cannot see that happen to the sport I and so many other Brits love.

Pest Analysis of Tyre Industry
PEST ANALYSIS OF TIRE INDUSTRY Tire Market in India is growing strongly and their production increasing from every year. In 2005, there were 40 tire manufacturing companies working in India which was consisted of major big brands in tire industry such as Good year, MRF, Falcon Tires and Bridge stones etc. we apply pest analysis on this market to check at what extent political, economical, technological and social factors are affecting this tire industry in India. POLITICAL: The government policy is much favored too local manufactures as said by the managing director of Goodyear India in 2005 that the tire market in India was almost exclusively dominated by local players and 90% of all tires on the Indian market were made and sold by the local Indian companies so Big companies like Good year, Michelin etc are hardly visible in India Tire Industry ââ¬Å"Indianizedâ⬠Government is providing more leverage to the local market that the foreign tire companies coming towards India. In 1926, when big giants in tire manufacturing like Dunlop, American firestone, Goodyear and Italian Ceat had much capital started their production plant in India than this had been a big treat for the local tire market. So Indian Government Immediately took an action and made a policy that if any foreign tire manufacturing company wanted to start their tire business in India than they had to act as locally and their names also seemed like locally such as Dunlop changed into Dunlop India and from Goodyear to Goodyear India. This ââ¬Å"Indianizedâ⬠process speeded up with the acquisition of most of the subsidiaries of foreign companies that operated in India: Firestone was bought by Modis in the early 1980s and Ceat and Dunlop were taken oven by RPG. Agreements with other foreign companies: There are many contracts and agreement of Indian companies with other foreigner companies which are as follows: * Under the Bangkok agreement, car and two wheelers tires were imported from china and South Korea at 10 percent custom duty. These imported tires had an average price 30 percent lower than tires sold by Indian companies. Some Indian companies like Apollo and JK tires tried to collaborate with Chinese companies in order to jointly produce cross ply tires. * In 1984, there was a agreement between the Indian and Japanese companies to get the model of Maruti 800 from Japanese company. * Ford and Dacia Logan are soon to be manufacture under the agreement by the Indian company with the foreign companies. ECONOMICAL: Growth of tire industry: The tire industry is growing in India day by day. In 1926, first tires were made by British company Dunlop. This gave rise to flourish of tire industry in India. When Cross ply tires were first introduced than 65 % of tire sales in India were covered by cross ply tires. But with the introduction of radial tire, radial tires represented 85% of car tire sales by volume. All the tire manufacturing companies are increasing their shares because tire industry in India is grooming with every year. In 2005, MRF, Apollo and JK tires had a tough competition and had a tough competition between them. Increases price of raw material: The prices of natural rubber and petroleum, which are essential components for the manufacturing of tires, becoming higher and higher which is badly effecting the tire manufacturing industry.

Real-World Green Chemistry Examples
Reals Green chemistry seeks to develop products and processes that are kind to the environment. This can involve reducing the waste a process creates, using renewable materials, lessening the energy required to form a product, etc. The US Environmental Protection Agency (EPA) sponsors an annual challenge for the most innovative green chemistry inventions, plus you can find examples of green chemistry in many of the products you buy and use. Here are some interesting sustainable chemistry achievements: Biodegradable Plastics Plastics being developed from eco-friendly renewable sources, plus some modern plastics are biodegradable. The combination of innovations reduces our dependence on petroleum products, protects humans and wildlife from undesirable chemicals in old plastics, and reduces waste and impact on the environment. Scientists atà NatureWorksà of Minnetonka, Minnesota, makes food containers from a polymer called polylactic acid, made usingà microorganisms to convert cornstarch into a resin. The resulting polymer is used to replace rigid petroleum-based plastic used in yogurt containers and water bottles. Advances in Medicine Pharmaceuticals are expensive to produce in part because of the complicated and exacting synthesis mechanisms required to produce some drugs. Green chemistry seeks to streamline production processes, reduce the environmental impact of drugs and their metabolites, and minimize toxic chemicals used in reactions. Professor Yi Tang, of the University of California,à devised an improvedà synthesis process to makeà Zocorà ®, which is the brand name forà the drug, Simvastatin, used to treat high cholesterol. The previous process used hazardous chemicals and released a large volume of toxic waste. Professor Tangs process usesà an engineered enzyme and a low-cost feedstock. The company Codexis, then took the mechanism andà optimized the enzyme and synthesis process so the drug could be manufactured more safely, less expensively, and with less of an environmental impact. Research and Development Scientific research employs a number of techniques that use hazardous chemicals and release waste into the environment. New greener processes keep research and tech on track while making it safer, cheaper, and less wasteful. Life Technologiesà developed a three-step, one-pot synthesis method for polymerase chain reaction (PCR), used in genetic testing. The new process is more efficient, consumingà up to 95 percent less organic solvent and releasing up to 65 percent less waste compared with the conventional protocol. Using the new process, Life Technologiesà eliminates aboutà 1.5 million pounds of hazardous waste each year. Paint and Pigment Chemistry Green paints go way beyond eliminating lead from formulations! Modern paints reduce toxic chemicals released as paints dry, substitute safer pigments for some poisonous colors, and reduce toxins when the paint is removed. Procter Gamble and Cook Composites and Polymers formulated a soya oil and sugar mixture to replace petroleum-derived paint resins and solvents. Formulations using the mixture release 50% fewer hazardous volatile compounds.Sherwin-Williams created water-based acrylic alkyd paints that contain low levels of volatile organic compoundsà (VOCs). The acrylic paint is made from a mixture of acrylics, soybean oil, and recycled PET bottles. Manufacturing Many of the processes used to make products rely on toxic chemicals or could be streamlined to reduce the use of resources and release of waste. Green chemistry seeks to develop new processes and improve conventional production methods. Faraday has developed a plating process to make high-performance chrome coatings from trivalent chromium instead of highly toxic hexavalent chromium.

Prescriptive Design Models Essay Example | Topics and Well Written Essays - 500 words
Prescriptive Design Models - Essay Example Pahl & Beitz (1988) developed the systematic approach in design, and divided the flow of work into four distinct steps. According to Pahl and Beitz, the first and initial stage in prescriptive design is clarification of the task. This entails collecting enough materials regarding information of the project, the requirements of the specific design, and the constraints to be faced in the actual design work. These stages will prepare a learner psychologically by offering the background information regarding the design, what they are actually required to do and the limits in terms of requirements and the scope of the actual design. The second stage according to this model would be the conceptual design. This process as Pahl & Beitz explain involves establishing functional structures, searching for the most suitable and viable solution principles and combining these to form a concept or design alternatives. This approach broadens a learnerââ¬â¢s approach to have various ways in which t hey may approach the design process by understanding the component better through its functional dimension, and broadening the concept to find other design alternatives. According to Pahl & Beitz, after understanding the functionality of the component and having several design approaches, the next step would be the embodiment design.
