Optical Character Recognition for Kids Learning Essay

Education is the breeding and schooling which results from this process of principle or training. It is the academic discipline dealing with commandment and learning methods in the schools. training st arts at sept and the p arnts atomic number 18 their kickoff get a lineers to their kids. When they be intimately 4 to 6 years of age, parents are starting to lick their kidren at school where they are able to learn not only the basic skills much(prenominal) as take awaying and writing entirely excessively to expatiate simple logic and abstract ideas like effects, shapes, colors, succession and many more(prenominal). Yet, learning first how to hold open is by far the most classic lesson of all and is the precession of all those people who are instruct tykehood bringing up. Writing is a skill that is expenditured in all academic coursework as well as through a psyches victor and personal life. Children learn ab extinct reading and writing by thinking close the sounds that words dissemble and what those words visualize like when pen out. When clawren are eager to learn something, they want to explore it themselves. Nowadays, s fixrrens potentials are determined by their ability to learn the basics of writing and reading at their truly(prenominal) early age (Patterson C (2008).Child emergence. New York McGraw-Hill. ). In todays complicated world, the chronic advancing of technology has opened many doors when it comes to education. Technology has become an influential factor when it comes to education. This works savants the opportunity to accept what they are inte confronted in learning. Computers give up started to bring up a huge impact in our lives and begun to come out up not only in only offices and households, scarcely as well in classrooms, as they stir become cheaper, more powerful, and easier to use. on that point have been many packet applications bourgeoned for the purpose of education and for use in the classroom. Computers and mobile phones are use in developed countries both to complement established education expends and develop new ways of learning such as the concept of E-learning. It is the unifying term to get the fields of online learning, web-based training, and technology-delivered instruction. By adding inter use to teaching, Not only would the peasantren entrust be able to see what is involved, hardly he or she would be able to learn from knock overs on experience.Computers rout out be a in truth effective way of accomplishing this. The use of computers in Elementary schools is basically vision as teaching and learning sanction besides develop computer literacy amongst the nipperren. Computer Aided Instruction will inspection and repair us to make the present teaching learning process joyful, interesting and clear to understand through audio- ocular aids. instructors will be resourced with Multimedia Contents to explain topic better. Overall it will help us to rectify quality of education in long term. In this study, the proponents develop software that will be an aid for teaching children how to write by using stylus and be able to write on the fulfill screen monitor of the computer. A stylus is a pen-shaped instrument that is utilize to draw images, select from menus and write characters which come with unalike devices that contain touch screens. The finding are some of the reasons the proponents have develop such software (1)Time constraints. Considering it applied in classes, children are pres sealedd in terms of completing a given hired hand task which affects their performance. (2)Level of activities.Occasionally, activities that are held in classes may be inappropriate when it comes to the capabilities of the students. (3)Limited school activities. Children are only provided moderate amount of activities in school to learn a specific area in school oddly playscript. (4)Assessment procedure. Usually, it takes time for the instructor to evaluate the deal activities that they are providing for the kids. The basic handwrite software for kids will file certain gif format containing simple steps on how to write the earns and audio sounds to secern what letter should be written. Children sack trace uppercase and lowercase garner using the stylus and will be evaluated afterwards in a friendly manner. The platform will likewise contain a different order of teaching a child to write the alphabet and works back tooth be saved. The program has a quiz section that assesses the learning of the child without the aided instruction of gif format.To help children to construct correct handwriting, there would seem to be a case for the use of ru direct writing spaces and assist them to follow the proper procedure of writing a specific character and obtain precise strokes. There would likewise a field references or guidelines for line and cursive character in the every letter of alphabet. erroneous beli ef substances, if used, need to be in a simple English words that the children can easily understand. A different level of practicing is considered to be sure that children will be able to take hold of the writing proficiency through gif images that shows how characters should be constructed properly.An erase function will also be available as a feature for the children to make them avoid discouragement from scribbling out and overwriting. The children should see at the screen the characters they stand for to write and see the results produced after the program recognizes it and be able to see the evaluation of their performance afterwards. Children should be able to understand what was happening effectively. There will be a comment or message alert for every wrong input of the children. The group will use an Optical Character fruition (OCR) which is a subsystem for pattern recognition. Character recognition identifies the input handwriting and translates it into a machine langua ge or the ASCII. With OCR, the software could rank and evaluate the childs handwriting performance.When the child inputs the character the OCR will read and identifies whether the character is valid. If the character is valid the evaluation will takes place and calculate the handwriting performance of the children. There will be a set of points within a specific character that has a synonymous pock. Children will be evaluated gibe to the use of Back Propagation algorithm. Back Propagation algorithm will trace the input characters and get the error percentage. A deduction will be conducted to the total score of the user if he fails to follow the de signaliseated ordinates. Scores will be evaluated and will be shown as follows genuinelyly Good, Good and Fair.The software that will be implemented will serve as a teaching tool in developing handwriting skills of kids ages 6 and below only which can be used by pre-school teachers and parents as well. It is only an alternative way o f teaching basic handwriting rather than the traditionalistic way of learning. The validity of the software can be tested by parents, homeschoolers and teachers who have acquired the skills and knowledge in teaching the traditional process especially those teachers in nurseries and kindergarten.Chapter IIReview of Related LiteratureChildrens Early AgeChildren ages 4-5-6 need some attention and care and parents must be able to identify the interest of the child and what they are capable of. In this stage they will be responsible but they still need assistance. They can do simple things on their own like wearing clothes, tie their shoes, brushing their teeth and early(a)s. In this stage of increment they have their own specific interests like acting blocks, dawdling and separate(a)s. Play with other children who need what she needs and like what she likes, who understand her because they are the same age, becomes very important to most children. By the age of 4-5 children can now accept the social interaction with other children. (Irma Simonton Black, Children from 4-5-6)There are other activities in this early age that are very short enured to parents like dawdling but according to Black Dawdling may be a childs indirect way of asking for help, of asking for the warmth and quick affection of his babyhood. If the child needs parents help they must give them a full hand but remember that there are some help that can be done by the child like putting and tying their shoes. The office staff of a parent is to be subservient, sympathetic and patient. Parents must also praise for the things that the child accomplish rather than disapproval of the things the he/ she did not do. Children are very easy to learn but they must need guidance and care. ThE-learning capabilities of children need time and patience. (Ruth Mason 2000)Schoolchild DevelopmentThe E-learning capabilities of this early stage is different they can develop a sense of logic and often sticks w ith a problem until he/she has solved it. They can gain a sense of satisfaction from tackling simple number problems. These new ability gives confidence in developing and expressing on their own point of view. They can also grasp more abstract ideas, like numbers, time and distance. During this time the brain undergoes its most dramatic growth, and children promptly develop the cognitive capacity that enables them to become intellectually curious and creative thinkers. In this child development they can now focus on their interest like reading books on related theater that are taught in the school. They can now express their point of view and reasoning. (Graham, Rob and Hess, Heidi) There are also circumstances that hinder childs development and this is thE-learning Disability this causes a person to have troublE-learning and using certain skills.The skills most often affected are reading, writing, earreach, speaking, reasoning, and doing math. Learning disabilities (LD) vary fro m person to person. adept person with LD may not have the same kind of learning problems as another person with LD according to National Dissemination Center for Children with Disabilities. Learning Disability is not a sickness but this situation are caused by the different approach of processing the brain. Learning Disability does not allow in visual, hearing and labour disability and also mental retardation. There are no concrete sign of having learning disability but by observing them you can actually identify and these signs are helpful may have troublE-learning the alphabet, rhyming words, or connecting letters to their sounds may make many mistakes when reading aloud, and reprize and pause often may not understand what he or she reads may have real trouble with spelling may have very messy handwriting or hold a pencil awkwardly may learn language late and have a limited phrase may have trouble understanding jokes, comic strips, and sarcasm may have trouble next di rections may mispronounce words or use a wrong word that sounds similar And to help children with this disability parents must identify the strengths of their child. The parents must praise the good things about their child with this disability .And for teachers they can help their child with such disability by breaking tasks into smaller steps, and giving directions verbally and in writing giving the student more time to finish schoolwork or take tests allow the student with reading problems use textbooks-on-tape (available through Recording for the Blind and Dyslexic, listed under Organizations) letting the student with listening difficulties borrow notes from a classmate or use a tape recorder and letting the student with writing difficulties use a computer with specialized software that spell checks, grammar checks, or recognizes speech. (National Dissemination for Learning Disability)Childrens School LevelThis is often categorized in pre-school and kindergarten levels. Pr e-school is the preparation ground for children, this shows how kids will they be when they are 7 because of different aspects. In this level of education children only go to school for an bit which includes performing and 20-30 minutes of listening. The schools strategize a three days per week at an academic program and 2 days per week at a play-based school, hoping to achieve the best of both worlds.Preschool are very self-absorbed which they believe everyone sees the world as they sees it. They still dont know what is the cause and effect and they give a process that is not logical and complex. They also focus on one crimsont and dissolve the other. According to Martha E. Mock Young children learn best through meaningful interaction with real materials and care adults and their peers, not through the drilling of isolated skills. Preschool approach is everydayly a play-based program to enjoy child academically and socially. After they excel in preschool year they can now st ep to kindergarten where they can formally in different approach.(Laura Davy, 2007)Kindergarten is being called nowadays as a new first grade of education. only be sure that your child is ready for kindergarten and there are signs to identify that are being analyse by parents. This checklist are created by the National Center Disabilities Inc,. The purpose of kindergarten is to show the child the good feelings about learning and school. This is the building block for stepping in first grade. The curriculum starts by building familiarity with a dewy-eyed number of aspects of the written and spoken word. In kindergarten the general trend of teaching is basic literacy and writing t hat is covered for first grader. The students taught a basic curriculum in all subjects, including science, social studies, and arts but the most important academic topics will be literacy, handwriting exercise and math, which underlie everything else to come. mitt and dawdling is the common tool for exp ressing childrens idea and taught. (Julie Williams, 2007) playscriptHandwriting is the first education that is undeniable for children. This is important because research shows that when children are taught how to do it, they are also being taught how to learn and how to express themselves. Handwriting is the best way to express childrens idea and feelings to their loved ones and friends. Emily Knapton, director of program development at Handwriting without Tears, believes that when kids struggle with handwriting, it filters into all their academics. Spelling becomes a problem math becomes a problem because they grow their numbers. All of these subjects would be much easier for these kids to learn if handwriting was an automatic process.In the research led by the professor of Venderbilt University, Steve Graham he assemble out that teachers believe that students with fluent handwriting produced written assignments that were superior in quantity and quality and resulted in proude r grades aside from being easier to read. Evidence is evolution that handwriting fluency is a fundamental building block of learning. It should be exciting and an enjoyable activity through which children can experience success. If we stop teaching penmanship, it will not only hasten the dread day when brides acknowledge wedding gifts by e-mail the bigger danger is, theyll be composed even more poorly than they already are. According to Baggett, changing a childs handwriting can improve their grades, their behaviour, and their self-esteem. (Raina Kelley, 2007)Process of Teaching HandwritingIn teaching the children the best way is to write their reach first. Begin with lower case letters, rather than capital letters. This mechanism will help the child when first encountering reading and writing because lower case letters are commonly seen in the books. (Shirley Erwee et.al)The time coupling in teaching is between 20-30 minutes to avoid boredom. If the parents teach the child to w rite in blown-up interval of time they will lost their interest. Their eyes are not that fully developed so they have no focus on every book or page like adults. This technique will avoid childs eye strain and the limit is 15-20 minutes. Encourage the child in continuing handwriting coiffures and praise the work of the children. Do not compare the work of the child to the other children because they have a process in developing this talent. (Sandhya S. Naidu)1. OVERSEE HANDWRITING PRACTICEWhen children are practicing handwriting it is very important that you oversee their work so that they do not develop bad habits. emergence over some inappropriate letters so that they will not rooted to it.2. ONE quarry AT A TIMEFocus on correcting or up(a) one objective at a time be it a particular letter, spacing, size, alignment, etc.3. PRACTICE DAILYHandwriting practice should be scheduled every day but keep lessons short for best results.4. CORRECT draw GRIPCorrect pencil grip allows a writer to write quickly and smoothly, while a tight or awkward grip can hinder writing.5. PROPER POSTUREBe sure that your child is sitting properly at a surface that is not too high. Her arms should rest comfortably and her feet should be reserveed (by the floor or a box), rather than hanging loosely. This is to avoid hold out and bad habits which may develop as a result of improper posture. Monitor your childs posture regularly.6. BE PATIENTImprovement in handwriting requires a combination of skills and developmental maturity. distributively child will progress at her own rate. Remember that fine motor skills develop more slowly in boys, than gross motor skills.7. KEEP HANDWRITING SEPARATEKeep handwriting practice or copy work separate from composition and other writing tasks, which require attention to other skills such as focus on contentedness, organizing ideas, editing, spelling, punctuation etc. so that students will not be reluctant to write.Assessing Child HandwritingAc cording to Occupational Therapy Handwriting Resources in assessing childs handwriting there must be clinical manifestation skills. There are different clinical observation skills and uses according to purpose.The childs proper grip in pen or pencil is important because improper grip can cause fatigue and joint problems. The proper grip is the normal propulsive tripod give where the thumb is placed at the side of the pencil and the index finger is placed on the top of the pencil. The pencil is stabilized on the side of the middle finger. This position allows for needed stability and mobility. uncomely grip can cause lead to joint problem and early fatigue in written assignments tightness or pain in the thumb web spaces(Occupational Therapy Handwriting Resources)The Evaluation Tool for Childrens Handwriting (ETCH) is an assessment that ensures the legibility in word, letter and numeral percentage, as well as letters per minute. Pencil take for, near and far point copying, manusc ript to cursive translation, dictation and sentence completion are included.The Bruininks Oserteksy Test of Fine Motor Proficiency assesses motor proficiency of students without disabilities, as well as those with sobering motor dysfunctions and developmental difficulties. It is administered to children from ages 4 years 6 months to 14 years 6 months. Occupational healer typically administer only the fine motor development subtests which include response speed visual-motor control upper-limb speed and dexterityThe Peabody Developmental Motor Scales is composed of six subtests that measure inter related motor abilities that develop early in life. It assesses the motor skills of children from birth through 5 years of age. Occupational healer typically administers the grasping and visual motor subset. (Occupational Therapy Handwriting Resources) The assessment for teachers is based on the books and criteria. Teachers tend to teach children according to books instruction. The child n eeds some patience and virtue to achieve a good handwriting skill. This skill can visualize the childrens future and development.Handwriting as a Symbol of winnerThere are also instances that penmanship and handwriting predicts success according to Bart Baggett. They also identify the handwriting of Michael J. Fox , Martin Luther King and Oprah Winfrey which shows success. Baggetts identify the seven personality traits according to stroke that are common to successful people. High Goals and Ambition (t-bars crossed on the top of the stem) slopped self-esteem (Large signature and high crossed t-bars) Determination (heavy downstrokes below the baseline) Persistence (not picking up your pen when you cross the letter t) Strong Physical Drives (large and heavy y and g loops) Long Lasting Enduring Emotions (pressing very hard on the paper) Enthusiasm (extra long strokes to make the crossing of your t) Handwriting is an important task to learn by the child and need some proper inte raction to their instructor or teacher and also parents. (Yenra, 2007)Interaction for TeacherThe quality of interactions between teachers and children plays a key role in accounting for gains in childrens development when compared to typical quality indicators such as teachers education, class size, and child-to-teacher ratio. High-quality instructional interactions happened when teachers provided children with feedback on their ideas, commented in ways that encompassing and expanded their skills, and frequently used discussions and activities to promote complex thinking. Teachers by doing this teacher-child interaction the children can improve or develop good cognitive, socio-emotional and language skills. Interaction could help children understand the knowledge he/she wants to gain, like media that are so interactive nowadays. The size and number of the students is not the basis for thE-learning of the child but the interaction of the teachers to them. A child learns a large amou nt of knowledge with the help of the emotional interaction. (Physorg, 2008)Childrens Interact EmotionallyIn early stage children does not only learn social skills and language but they also learn the act of sensitivity and emotion. Having a social interaction helps child to develop their logic and sense of reasoning. With this emotional interaction they can decrease their fear in reasoning out or expressing their emotion. Interaction benefits every child very much, because they not only get one on one time to talk to their teacher but they also produce positive relationships between teachers and students. Teachers by doing this teacher-child interaction the children can improve or develop good cognitive, socio-emotional and language skills. There are also materials that are very interactive to children and they could gain knowledge with this interaction. Technologies nowadays are very interactive to child which helps them to learn more. (Killi, 2008)TechnologyAccording to studies an d researches more and more kids are applying technology to their lifestyle like playing video games, using computer and watching TV. According to parents using media and technology children helps to learn while entertained. nowadayss children might use their brain differently than the kids in previous generation this is according to UCLA professor, Patricia Greenfield. Patricia Greenfield found out that TV, Media and video games does not limit the mind of the children but they also help them in other ways. In a concrete result they found out that surgeon who has a skilled in video games can be better in keyhole surgery.The use of technology can have a great effect of schools. With an increased emphasis on more teacher discretion over teaching and learning in the classroom has a potential to increase. Technology can also be coordinated into the class through the use of software. Technology allows the student to comprehend the subject matter at hand easier. The children nowadays are better than their ancestor when it comes to multitasking as a result in complex visual information that they deal with. The school, learning institute and parents must understand this study and apply to their learning techniques according to the UCLA professor. (Patricia Greenfield 2005)Technological Adaptability in EducationMany different types of technology can be used to support and enhance learning. Everything from video content and digital moviemaking to laptop computing and handheld technologies (Marshall, 2002) have been used in classrooms, and new uses of technology such as podcasting are constantly emerging. Various technologies deliver different kinds of content and serve different purposes in the classroom. For example, word processing and e-mail promote conversation skills database and spreadsheet programs promote organisational skills and modeling software promotes the understanding of science and math concepts. It is important to consider how these electronic technol ogies differ and what characteristics make them important as vehicles for education (Becker, 1994). Each technology is likely to play a different role in students learning. Rather than trying to describe the impact of all technologies as if they were the same, researchers need to think about what kind of technologies are being used in the classroom and for what purposes.Two general distinctions can be made. Students can learn from computerswhere technology used essentially as tutors and serves to increase students basic skills and knowledge and can learn with computerswhere technology is used a tool that can be applied to a mixture of goals in the learning process and can serve as a resource to help develop higher order thinking, creativity and research skills (Reeves, 1998 Ringstaff & Kelley, 2002). The primary form of student learning from computers is what Murphy, Penuel, Means, Korbak and Whaley (2001) describe as discrete educational software (DES) programs, such as integrated learning systems (ILS), computer-assisted instruction (CAI), and computer-based instruction (CBI). These software applications are also among the most widely available applications of educational technology in schools today, along with word-processing software, and have existed in classrooms for more than 20 years (Becker, Ravitz, & Wong, 1999).While DES remains the most commonly used approach to computer use in student learning, in more recent years, use of computers in schools has grown more diversified as educators recognize the potential of learning with technology as a means for enhancing students reasoning and problem-solving abilities.In part, this shift has been driven by the plethora of new information and communication devices now increasingly available to students in school and at home, each of which offers new affordances to teachers and students alike for improving student achievement and for meeting the demand for 21st century skills describe earlier. No longer limite d to school labs, school hours and specific devices, technology access is increasingly centered on the learner experience. Bruce and Levin (1997), for example, look at ways in which the tools, techniques, and applications of technology can support integrated, inquiry-based learning to engage children in exploring, thinking, reading, writing, researching, inventing, problem-solving, and experiencing the world.

Biography of Fashion Designer - Manolo Blahnik Essay

chronicle of flair Designer - Manolo Blahnik - Essay ExampleThe essay Biography of Fashion Designer - Manolo Blahnik dis directs the Manolo Blahniks biography. Together with Evangeline, his younger sister, they both underwent education at home since their family often travelled to Paris and Madrid. It was during those times when his interest in horseshoe-making started under the influence of his mother improvising and making of Catalan espadrilles from ribbons and laces. Blahnik enrolled for a politics and law major at the University of Geneva but later shifted to literature and architecture. After graduating in 1965, Blahnik move to Paris to study art at L moolah des Beaux-Arts and Lcole du Louvre while working at GO, a vintage clothing store. In 1968, he moved to London and enrolled at a language school to master the English language but worn-out(a) most of his time watching films in the Leicester Square cinemas. To step up his career of becoming a stage set source, Blahnik w ent to New York to present his portfolio of drawings and set designs to Diana Vreeland, then editor of US Vogue. Vreeland looking at Blahniks designs exclaimed How amusing. Amusing. You can do accessories very well. Why dont you do that? Go arouse shoes. Your shoes in these drawings are so amusing, referring to a sketch of a fantastical shoe which crept up the ankle entwined with ivy and cherries. After that inspiring moment, Blahnik went back to London in 1972 and begun designing for Zapata, a boutique on Old church Street in Chelsea (Craven). He started designing mens shoes.... Ossie Clark, a flashy fashion designer, was quick in noticing Blahniks talent and so requested for Blahniks designs for his next runway show. Eventually, Blahniks shoes got popular for Vogue editors even for a vintage Hollywood star like Lauren Bacall. He was more inclined to learn the craft of shoe-making, and thus, searched for a troopsufacturer in Walthamstow, north east of London to perfect this skil l. Thereafter, British Vogue made Blahnik as the first man ever to appear on its cover in 1974 (Design Museum). A year before being the cover of the famous magazine, Blahnik bought Zapata from its owner with the help of a ?2,000 loan. He ran the business with his sister, Evangeline. The designer continued working with the bad fashion icons like Jean Muir, Fiorucci and Ossie Clark. Slowly, he made his market in the US by creating a collection for Bloomingdales in 1978, opening his first store at Madison Avenue, New York in 1979, and designing shoes for Perry Ellis in 1980. Blahniks business took off in the US in the early mid-eighties when George Malkemus, a young copywriter, became his US business partner, leaving him and Evangeline taking charge of the business in Europe. Blahniks fame became unstoppable as he was also designing shoes for Calvin Kleins collections in 1984 (Design Museum). Years after, the designers creativity and hardships were recognized as he received a special award from the Council of Fashion Designers of America (CFDA) in 1987, Accessory Designer of the Year by the British Fashion Council in 1990 and 1999, La Aguja de Oro (The Golden Needle) in Spain in 2001, and La Medalla de Oro en Merito en Las Bellas Artes by Juan Carlos I in 2002. He was also honored with a retrospective exhibition of his drawings, memorabilia and

P53 mutations and Cancer Essay Example | Topics and Well Written Essays - 1000 words

P53 mutations and Cancer - Essay ExampleThe genes argon codes that instruct the cadre how to make many different proteins. One gene codes for one protein. In a crabmeatous jail cell some of the genes bring forth been damaged or lost. And this is termed as mutation. A mutation may mean that as well some(prenominal) protein is madeor that a protein is not made at all. There be three different types of genes that ar important in making a cell cancerous genes that encourage the cell to multiply genes that lay over the cell multiplying and genes that repair the former(a) damaged genes.Some genes encourage multiplication of cells. In general these genes atomic number 18 only activated during repair after a wound or an operation in an adult. scarcely if these genes become abnormal, they instruct the cell to multiply all the time and are termed as oncogenes or in other words are the cancer genes. There are also those genes that instruct the cells to stop multiplication and these a re the tumor suppresser gene genes. These are genes are in the cell particularly to stop the cell multiplying or doubling. They act as the natural brake to the oncogenes accelerator. Here again the problem is accelerated if one of these tumor suppressor genes becomes damaged and stops working. As a result the cell may then carry on multiplying. In other words it becomes immortal, which is one of the properties of a cancer cell. The best known tumor suppressor gene is called p53. ... Disruption of this gene is associated with approximately 50 to 55 percent of human cancers. In other words it can be said that the p53 protein acts as a checkpoint in the cell cycle, either inhibiting or initiating programmed cell death. Hence p53s has an important role to play when in comes to cancer which is nothing but undisciplined proliferation of cells. At this point of time there is other question that arises in our mind. If people have a built-in tumor suppressor then why do so many get cance r Research suggests that there are several factors that determine the p53 molecule activity as it can be inactivated in several ways. Genetics plays an important role, for instance, in some human families if p53 mutations are inherited the family members have a high incidence of cancer. However in many cases the molecule is inactivated by an external source. For instance, deoxyribonucleic acid tumor viruses, such as the human adenovirus and the human papilloma virus, have a tendency to declare to and inactivate the p53 protein function, which invariably alter cells and initiate tumor growth. Besides, some sarcomas amplify another gene, called mdm-2, which produces a protein that binds to p53 and inactivates it, much the way the DNA tumor viruses do (Burley n. pag). Hence it can be said that there are several factors that determine the functioning of p53 molecules. There is another way in which p53 molecule can stir up the cancerous growth in human body. In a normal cell, p53 prot ein binds DNA, which in turn stimulates another gene to produce p21 which is another protein molecule. The p21 protein in turn interacts with cdk2 which is another protein that stimulates cell division. If for any reason p21 binds cdk2, the cell cannot continue through the cell cycle and does not

Chinese classroom culture and American classroom culture Thesis

Chinese teachroom nicety and American classroom culture - Thesis ExampleA classroom culture of self-reliance and transparency is the foundation for creating an milieu where students are empowered with correct and appropriate feedback helping in effective learning along with religious offering them a chance to learn from their mistakes resulting in the achievement of common goals and objectives in a planned manner. It is classical to create a trusting environment as it helps students to learn along with offering learning to differents through experiences. However, different countries take different approaches to design their classroom culture based on the goals and objectives formulated by the supervisory bodies. A trusting classroom environment embedded with transparency helps in winning the trust of students along with offering them a robust platform of learning and invaluable experiences through course books and ain learning and sharing (Chalker, Haynes, 1994). The next p art of the discussion presents an insight over Chinese classroom culture in terms of ideas and methods used to enhance the learning of students. Chinese Classroom Culture The educational carcass is China is more of Socialist oriented where sharing of ideas and knowledge is considered as the prime gene of learning. Chinese classrooms are often packed with up to fifty students and learning is driven by group activities and discussions that is an element of socialism. Chinese schooling is extremely competitive that means students have to compete at the grade school level by sitting in competitive exams and working hard to ensure high grades in order to het admission in best of schools. The Chinese education dust can be considered as a stepping stone for the success of the economy in many ways. Students are compelled to succeed in order to serve the society and any sort of lagging behind may singled them out and hence creating extra amount of pressure that often affects their learni ng capabilities. The motivation for jump outlence is quite different in China compared to other countries as China emphasizes on creating productive citizens who can serve the society and kingdom along with creating value for the nation. In Western countries, children may have individuals goals and dreams to become wealthy but in China, the entire focus is on enhancing the level of productivity so that the nation can be served in a productive manner. This has created extra burden on students in order to be competitive and excel in their fields. China has a large population and often space becomes an issue especially patch accommodating 50-60 students in a single class. This is why classes are very near to each other separated only by walls. On the other hand, teachers share common room that mitigates hierarchies across academe and barriers to channelize with other teachers.
