China Education System Needs

China Education System Needs to be Changed on College Entrance Exam Introduction Getting up at 6 a. m. in the morning, after breakfast, then go to school to begin reading books or reciting textbooks. This was how I began my school life when I was in high school. I start my school life and study at 7 a. m. in the morning and until 9 p. m in the evening. When all my classes were over I could back home, but it did not mean that I can relax and go to bed. When I back home take a shower and continue studying until midnight. When I start our second year in high school, I need to choose a major: arts or science.I choose arts in high school, so except Chinese, math and English, which everyone need to learn, I also needed to take politics, history and geography class. For sstudents who chose science, they need to take physics, biology and chemistry class instead. All Chinese sstudents have to study so hard for a reason: the college entrance exam, also called â€Å"gaokao† in Chinese. T here are over ten million sstudents taking this exam every year in China. Only a small group of sstudents can pass this exam to get into the top university and get further education.When we take the college entrance exam, and sstudents in different majors need to take different exams. There are two different tests, one for arts and one for sciences. And sstudents who major in arts need to remember lots of information; sstudents who major in science need to lots of homework. Many sstudents who cannot pass it may continue studying and take gaokao the next year or just go to a university that is not so good. As our parent's say, this is an exam that decides our whole life. So, it is easy to know how much pressure we have when we face this exam.I want to argue in this essay that I think China should provide the college entrance exam twice a year and, furthermore, should avoid using the exam alone to determine which sstudents can attend the best colleges. Making these changes can reduce the pressure on sstudents so that they can enjoy themselves and pursue other academic and non-academic interests. Some Background about â€Å"Gaokao† The gaokao that we take today was began at 1978. At first it was held in July every year, from 2003 it begins hold in June every year because July is too hot.In China, the Compulsory Education Law that every single child must receive education at least for nine years. They need to start learning in kindergarten between age three to six. After three years in kindergarten, they need continue through primary school, middle school and then, for some people who have privilege to get higher education. There are two different levels of Chinese universities. The first category awards undergraduate diplomas and bachelor degrees following four years of study, whereas the second group awards undergraduate diplomas after two or three years. To enter these universities sstudents must sit the gaokao.According to an author Davey, â€Å"The ex am in China is ultimately under the control of the National Examination Authority within the Ministry of Education. The Ministry of Education co-ordinates and oversees the writing of exam questions, whereas lower-level government is responsible for printing and delivering the exam papers, as well as arranging exam centers, marking and reporting results â€Å"(Davey, 387). After several decades gaokao has become the most important exam for all China sstudents. Every year in June 7 and 8, two days that gaokao hold, it is just like a festival for examination.Sstudents take exam in local schools but not the school where they take class every day. When we enter the examination hall we cannot bring anything but a pen and student card. There is no calculator and dictionary when we take exam. On the first day of exam, we take Chinese test in the morning for two and half hours. In the afternoon we take the mathematics for two hours. It is a hard time when we finish our first day of exam. I remember when I finished the first day of exam, I felt a little bit relax because I pass math exam that was the most difficult part for me.I just glanced over my politics and history books prepared for next day. On the second day of gaokao, sstudents who major in arts take the test including politics, history and geography in the morning. Sstudents who major in sciences need take the test including physical, chemistry and biology. Last test is English in the afternoon of second of exam. In these two days police will come out to direct traffic and make sstudents can arrive to examination hall on time. Paren'ts are all worried about their children and many of them just stand outside of the examination hall wait till exam is over.It is a very common phenomenon through this time period. For us, when we start our school life, be successful in the gaokao is our ultimate goal for every student. It is just like a battle that have no gun and smoke. It is very obvious to know why we have no t ime to enjoy our spare time to play games, or just hang out for a day. The exam is very stressful, when we start to prepare for it is stressful as well. Less time to sleep, when we get into last year in high school, we even have no PE class just major classes all day long.Zheng, a writer from Research Center of High Education Development introduces that, â€Å"As the most important educational examination system of present-day China, the college entrance exam, while shouldering its original task of selecting qualified new sstudents for colleges and universities, also â€Å"holds multiple jobs,† pperforming educational, cultural, political, and other multifaceted social functions† (Zheng, 15). Gaokao even cares about our future career. A student graduate from the top university have a better chance to get good job than a student just graduate from normal university.The argument Zoninsein, a reporter from Slate Magazine argues â€Å"Essentially, Chinese universities acc ept those sstudents who are good at taking tests. This makes sense for an educational system historically oriented toward rote learning, where sstudents are tested on how well they've memorized their teachers' lectures. Mary, who is about to graduate from the Beijing Foreign Languages University, admitted she had many brilliant friends who simply didn't test well. They retook the test after another year of studying and enrolled wherever their scores permitted† (Zoninsein).As we all know, China has the largest number of people in the whole world. It is easy to image that how much pressure that Chinese sstudents face when they need to find a job. There is a social phenomenon have been in China for so long that if a student graduates from top university it mearns that he or she can find a good job. Benjamin a reporter from TIME net report this in 2007: â€Å"This year, close to 10 million Chinese sstudents sat for the gaokao, starting June 8. Sstudents who perform superlatively can expect to be courted by the nation's top schools; the rest find spots in provincial universities or two- and three-year colleges.For the 40 ppercent of test-takers who fail, there's always next year — or enrollment at one of China's less-selective private institutions. As China's economy booms, job competition has become ferocious — and the pressure to land a prestigious degree can be unbearable†(Benjamin). Indeed, there are also many unfair phenomena in the college entrance exam. For example, sstudents who take the exam in different place may get different grades during the exam. Sstudents who live in big city like Beijing and Shanghai can pass this exam easier than the sstudents who live in region area.Because there are many good universities in Beijing and Shanghai, when they enroll new sstudents they need sstudents' grades for gaokao, the university treat local sstudents and nonlocal sstudents in different way, they treat local sstudents better than nonlo cal sstudents. For instance, two sstudents get the same grades in gaokao, one of them is local student in Beijing, and the other one is not a local student. In this situation, the local student can get enrolled in Beijing University but the nonlocal student may not. The exam seems to create inequality among Chinese sstudents in different regions.

The Justification Of Nazi Officer s Actions During World...

Everyone has been there before. You re walking in public, whether it be in a school setting, a workplace, or elsewhere, and you feel an overwhelming feeling of being watched and judged. Whether it is your dabblings in romance, performance in sports events, clothing, or otherwise, we feel the need to compare ourselves to and identify with the societal â€Å"norms† around us. It is better to thrive as a sheep than to starve as a wolf, as the saying goes. This is what is known as conformity and it has been with us from time immemorial.

However, the voltage was labeled incorrectly and inflated as to intimidate the subject. As the rooms were adjacent, the subject could hear Milgram’s colleagues cry out in agony when they were shocked, and the subject began to start questioning the researcher about the condition of their â€Å"student† and asked, and eventually demanded that they could leave. Each time, the researcher would provide a prod to continue forth. If one prod was disobeyed, then the researcher would escalate to the next prod. The prods were â€Å"1. Please continue.†, 2. †Å"The experiment requires that you continue.†, 3. â€Å"It is absolutely essential that you continue.†, and 4. â€Å"You have no other choice than to continue.† After eighteen variations on the study, Milgram found that 65% of all participants continued to the supposed 450 volts and all participants went to at least 300 volts. Milgram concluded that ordinary people tend to follow an authority figure in a group, even to the torture and killing of a human being, if the authority’s actions seem to be rooted in correct morality and/or legality.

The Problem Of Depression Programs - 849 Words

Which brings us to what schools are currently doing, which they rarely implement the ideal practice causing problems overall. As stated previously, schools have a tendency to treat these issues as independent problems causing the institution to spend an abundance of money on multiple programs when one or two would suffice. This attempt to penny pinch has lead schools to implement programs such as late starts (one day every two weeks or month that has a later start time) and sleep education (that tries to teach students about sleep so they go to bed earlier) (). In both cases, the programs pull on part of the suggested action (delayed stat times, educating students) but do it in a way (inconsistent, fully on the student) that prevents the program from being as effective. In some cases, such as temporary late start times, it makes the problem worse (). The same can be seen for the other two. Depression programs are either put fully on the teachers or one counselor so they cannot give a dequate support because of lack of knowledge or time, or they are pushed out-of-school by having students redirected to community resources which they might not be able to offered or use. Again, the school is trying to bring in parts of the ideal (get teachers involved, use community resources). It is being done in a way that diminishes or destroys any positive effects. There is an exception with dropouts as many school feel they need to implement stronger programs then the ideal.

But where a DSP takes informations in from a beginning, processes it, and passes it on, the transputer had four channels of bi-directional communicating, or links. That made it simple to construct a planar array, each transputer associating to four neighbours.

TRANSPUTER ARCHITECTURE: First coevals of them are 16 spot transputers: T212, T222, T225 ( The 212 ran at 20MHz both the T222 and T225 ran at 20MHz. ) ; 32 spot transputers without a drifting unit: T400, T414, T425, T426 ( the T414 was available in 15 and 20MHz assortments, T425 in 20, 25 and 30MHz assortments ) ; 32 spot transputers with a drifting unit: T800, T801, T805 ( the T805 was besides subsequently available as a 30MHz portion. All have the same direction sets, the same architecture and to the full compatible communications links. Second Generation 64 spot transputer with a drifting unit: T9000. Although the architecture is the same, it is a new design and is really more complex bit than its predecessors. All the transputers except T9000 has indistinguishable architecture. The internal coach connects the processor to local memory and to an external memory interface. The communicating links are connected to the coach by an interface. This makes it possible for the processor to work independent of the links. Depending on the type of transputer, the drifting point unit and other system services are besides connected to this coach. In figure1 T805 is the celebrated one. It consists of a conventional, RISC processor, a communicating subsystem, four Kb of on-chip RAM, four high-velocity inter-processor links and a memory interface, system services and a floating point. These functional units will briefly explains in the undermentioned subdivisions. The procedure: A procedure on the transputer is described by several pieces of information, such as workspace, registries, plan and precedence. Such a procedure does non hold to be a consecutive procedure but can besides dwell of several sub procedures. The procedures on the transputer can be separated in two classs: Active procedures: is a procedure which is executed or which is waiting for the following to be executed. Inactive procedures: is a procedure which is suspended at specific clip or which is waiting for inter procedure communicating. 2 Registers: â€Å" The transputer has a little figure of registries, a workspace registry ( Wreg ) , an direction arrow ( Iptr ) , an operand registry ( Oerg ) and a three registry rating stack ( Areg, Breg, and Creg ) † ( hypertext transfer protocol: //books.google.com.qa/books? id=zroYqxO9o3IC A ; pg=PA16 A ; lpg=PA16 A ; dq=Instruction+pointer, operand+register, workspace+register A ; source=bl A ; ots=fiv2ktQmIW A ; sig=AYGCR5W73DgjhP_TsIxyKS6HLkw A ; hl=ar A ; ei=IeIXS_jgIM2IkAXqo8TjAw A ; sa=X A ; oi=book_result A ; ct=result A ; resnum=5 A ; ved=0CBwQ6AEwBA # v=onepage A ; q=Instruction % 20pointer % 2Coperand % 20register % 2Cworkspace % 20register A ; f=false ) . The registries Areg, Breg, Creg are used as a stack, instead like early reckoners, to keep intermediate consequences. The registries Areg, Breg and Creg form a stack. Every direction notionally pops off the stack the points that it is traveling to work on, so pushes its consequence back onto the stack. This stack agreement is what allows most of the instructions to hold no operands. The agreement is like some programmable reckoner linguistic communications ( though such linguistic communications are much more limited ) † hypertext transfer protocol: //www.cs.bris.ac.uk/~ian/transput/page3.htm, † . There is no protection against forcing excessively many values on the stack that it overflows. ( It is left to compilers and assembly codification authors. ) .These characteristics leads to simplified registry connexion, compact instructions, faster register entree. Iptr, Wreg, Oreg: These are called consecutive control registries: Direction arrow ( Iptr ) , holds the reference of the following direction. Workspace registry ( Wreg ) , holds the workspace arrow ( Wptr ) which is the reference an country of memory called the local workspace. Operand registry ( Oreg ) , holds the operand for the current direction. It ca n’t be straight loaded from ( or stored in ) the informations portion of the memory Direction Set: All the transputers have the same direction format. Instruction Fetch State In order to bring the direction to be executed following: Iptr must be selected to Input for the reference coach in which Iptr contains the reference for the following direction, memory must be selected to the beginning for the information coach since the reference to be executed following which is kept in Iptr must loaded on the reference coach, Ireg must be set to the end product finish for the information coach, and the following reference of the micro-code ROM must be set to 0x001 to travel to the direction decode province. The specification is given in this province and is described in the micro-code ROM at reference 0x000.. Direction Decode State The contents of four higher spots of Ireg or Oreg 32bit are used to stipulate the following direction to be done. The following reference of the micro-code ROM is so determined conditionally harmonizing to the direction decoded. You read "Large Parallel Processing Systems Architecture Essay" in category "Essay examples" Instruction Execution State If the direction to be executed is finished in one province passage, so the following province will be back to the Instruction Fetch. Alternatively if the direction needs other provinces to finish, so the following reference for the micro-code ROM is an appropriate 1 for the following province. Floating Point Unit of measurement: â€Å" It is about independent of the remainder of the bit. It has its ain internal registries, separate from the registries used by whole number operation.It execute instructions to execute drifting point arithmetic operations, including platitude operation such as add-on or generation, and more complicated operations such as rating of some nonnatural maps like sine or logarithm † ( hypertext transfer protocol: //books.google.com.qa/books? id=I2TCERgkcCgC A ; pg=PA304 A ; lpg=PA304 A ; dq=floating+point+unit+has+own+stack A ; source=bl A ; ots=cVSlbfR1Av A ; sig=HdSpHb79OdVrp4QfRpkXyso-05I A ; hl=ar A ; ei=OFUZS5SuMM2TkAXbx4XfAw A ; sa=X A ; oi=book_result A ; ct=result A ; resnum=6 A ; ved=0CCEQ6AEwBQ # v=onepage A ; q=floating % 20point % 20unit % 20has % 20own % 20stack A ; f=false ) . It has its ain development stack registries FAreg, FBreg, FCreg. There are 53 floating-point instructions. High degree programming linguistic communication to plan is strongly advised instead than assembly. It bases IEEE criterions for the natation point format, operations and consequences: For the 32 spot Numberss ; 1 spot for mark, 8 spot for advocate, 23 spot for fixed-point part. For the 64 spot Numberss ; 1 spot for mark, 11 spots for advocate, 52 spots for fixed-point part. It besides supports such consequences Inf ( space ) , NaN ( non a figure and non defined ) . Timers: â€Å" The transputer has two timers, one that gives a tick every microsecond and one that gives a tick every 64 microseconds ( for the 20 MHz T414 ) . This can be considered another incommodiousness because the two timers are associated with a degree of precedence. Low-priority procedures can non utilize the high-resolution timer. This means it can go on that processes run needlessly in high-priority, all because of the fact they have to utilize the high-resolution timer † ( hypertext transfer protocol: //74.125.153.132/search? q=cache: RID6_SK4ugEJ: www.science.uva.nl/~mes/psdocs/transputers.ps.gz+The+transputer+has+two+timers A ; cd=6 A ; hl=ar A ; ct=clnk A ; gl=qa, Transputer, Jacco de Leeuw Arjan de Mes, October 1992 ) . System Servicess: â€Å" On all INMOS board merchandises the term ‘system services ‘ refers to the aggregation of the reset, analyse, and mistake signals. On the IMS B008 the system services for the TRAM in slot 0 can be connected to either the UP system services from another board or the system services controlled by the Personal computer coach interface. System services for the other TRAMs can be connected to the same beginning as TRAM 0 or to the subsystem port of TRAM 0. As shown in the block diagram the Down and Subsystem services are brought out to the 37 manner D-type connection leting this hierachy to be extended to multi board systems † . ( hypertext transfer protocol: //www.classiccmp.org/transputer/documentation/inmos/1861.pdf ) Link: ( Communication between procedures on the transputer is performed by two instructions input message and end product message. The communicating which is supported is a point-to-point, unbuffered message-passing strategy. It therefore requires a handshaking between procedures, which synchronises them. Communications over these links are controlled by independent accountants, which have DMA entree to the transputers memory ) ( hypertext transfer protocol: //books.google.com.qa/books? id=6HcBQ67-Fb4C A ; pg=PA358 A ; lpg=PA358 A ; dq=The+INMOS+Link+ % 2BDMA A ; source=bl A ; ots=esMJ1tFuhv A ; sig=7nu_kxm48ARMoIoerKLu4uMhVq8 A ; hl=ar A ; ei=kmAZS_GjAoqUkAWVpuDQAw A ; sa=X A ; oi=book_result A ; ct=result A ; resnum=3 A ; ved=0CBUQ6AEwAg # v=onepage A ; q=The % 20INMOS % 20Link % 20 % 2BDMA A ; f=false ) . They are highly flexible and can be used for, interfacing with peripherals utilizing a nexus adapter, an ASIC ( Application specific integrated circuit ) bit can utilize a nexus to read and compose straight into a transputer memory at high velocity, most common to speak to another processor, normally anther transputer. Link Communication The hardware connexion of links is simple, short distances. Linkss are consecutive port. if you see the figure for each nexus connexion merely two paths are required. In transputer the processor and four links have independent entree to the memory. The processor sets up a nexus and after that it freedom to put to death other codification while dedicated nexus logic handles the communicating. All these four links can be outputting and inputting while the processor is running codification. Of class there may a job with bandwidth when processor and all links entree memory at the same clip. Because the links designed the transputer do non necessitate to be synchronized in order to speak each other. T9000 Second Coevals: â€Å" The T9000 is the latest coevals of Transputers from INMOS. It represents an betterment on the bing coevals of transputer merchandises in both capableness and public presentation. The T9000 extends the transputer architecture in a figure of ways. The most of import of these is that the T9000 transputer decouples the physical connec-tivity of a system from its logical connectivity. Between any two straight connected T9000 transputers. there may be established an about limitless figure of The T9000 nexus system besides enables transputers to be connected via a web of C104 package routers which allows practical channels to be established from any transputer to any figure of other transputers. Other extensions of the architec- ture include the sweetening of the procedure theoretical account to supply per-process mistake handling installations and the ability to run plans under memory manage- ment.The T9000 has approximately ten times the public presentation of a T805. This betterment derives from a assortment of beginnings including the usage of caching, betterments in semiconducting material engineering, and a extremely pipelined, superscalar processor † .

Dominant Culture in America free essay sample

A dominant culture is one that is able through economic or political power, to impose its values, language and ways of behaving on a subordinate culture or cultures. This may be achieved by monopolizing the media and means of communication.? I would say the dominant culture in America is the pop culture. Pop culture influences the way we dress and even the way we talk. A lot of young people talk with slang words that their grandparents wouldn’t even understand. Pop culture affects everything we do, even the way we learn. We now have all these computers and gadgets to assist us in learning. Communicating with each other has been made so simple. We are constantly in touch with each other through Facebook and Twitter. Cellphones and texting make talking to one another so convenient. There is even a new written text language. Through computers and the internet, with the push of a button we can communicate with the whole world. We will write a custom essay sample on Dominant Culture in America or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Pop culture rules through the media, we are constantly bombarded by a generalized idea of how we should be, and how we should act. The media leads people to think they should look a certain way or act a certain way even though they don’t necessarily want to or feel comfortable doing so. Young people, women especially feel the need to be a certain weight or wear a specific size. Pop culture has even influenced diet. There are many diet fads that become quite popular, such as the Atkins diet, that people turn to and try in order to change their physical body to meet the popular standard. On the flip side of diet, pop culture has even influenced what we eat in a negative way. Pop star endorsed fast food restaurants have made picking up food so appealing and so easy that many Americans have become overweight. We are so numb to the fact that pop culture is leading our lives whether we want it to or not. The popular culture is a dominant culture due to the fact that it overpowers other cultural values and behaviors in America today.
