Turn: Why can't Chinese students learn well? Computer tan haoqiang

Professor Tan haoqiang is a well-known computer education promoter in China. He is also a well-known computer textbook writer in China. Professor Tan's book 《BasicThe book "language tutorial" sales reached 12 million, setting the Guinness World Record for sales of similar textbooks. When talking about computer education in China, Professor Tan believes that computer education in China is getting deeper and deeper. Professor Tan believes that the success or failure of computer education is determined by many factors, such as teachers, teaching materials, and teaching methods.On the surface, the types of computer teaching materials in China have maintained a high growth momentum, but in fact, the selection of computer teaching materials in schools has been restricted by all aspects. Considering that the quality of computer teaching materials will be closely related to the computer level of a generation of people, the problems have reached an unsolvable position.

 

Triple crisis affecting computer education

In Tan haoqiang Professor's opinion, there are three main causes of these crises.

one factor is that the relevant educational institutions take the number of bilingual teaching courses offered by the school and the number of original teaching materials used as assessment indicators. The publisher must meet this requirement, introduce a large number of original textbooks. Tan haoqiang Professor stressed that for many schools, this will only have disastrous consequences. The reason for this is that the assessment is based on a one-size-fits-all plan ". The teaching level of all schools is "one-size-fits-all". For universities like Tsinghua and Peking University, the foreign language level of instructors is high and the quality of students is high, it is a matter of course to conduct bilingual teaching and use the original teaching materials. In turn, for schools with relatively general teacher level and student source quality, teachers' oral skills are limited, and English Teaching often misleads students in pronunciation. For students, because of the limited listening level, professional courses have become listening courses. It is unfair for some teachers with high professional and general English proficiency, which will lead to a shortage of excellent teachers. In addition, the level of teaching materials prepared by local authors is not low (or even attract some overseas publishing institutions to promote overseas). At this time, what schools, writers, and publishers should do, we should not introduce the original textbooks, but consider creating our own brand internationally. In the long run, China's academic level is in line with international standards, and China's teaching materials will eventually be in line with international standards.

The second factor is that educational management institutions should plan teaching materials, compile teaching materials and recommend teaching materials, and include the proportion of such teaching materials used by schools in the assessment. The original intention is to make good use of the teaching materials, but the effect is not good because it is too formal. Tan haoqiang The professor said: "When you go deep into the review, it is not difficult to find the problem. It is impossible for more than a dozen judges and hundreds of books to read. As a result, a total of 10 books were reported, and the books to be eliminated were returned. In this wayCThe language will also review the operating system or books in other fields. As experts, these judges have their own strengths. However, if you review books that are not in your field of expertise, it is difficult to eliminate high-quality goods. Even more, it is difficult to find a group of young and middle-aged authors who are at the peak of their academic peak. Taking Academician WANG as an example, he made laser photos at the age of and was elected an academician at the age of. However, Academician WANG admitted that his academic peak was not the time when he was elected an academician at the age, it's the age of 38 years old laser shooting."

Tan haoqiang The professor went on to explain: "Even if you catch up with a level of judges, there may still be some problems. For example, professional judges of computer technology often do not want to select some simple books as non-computer-specialized books and materials, because this shows a level. But in fact, the criteria for determining whether a shortlisted person is a good choice for learners, rather than being 'Big, comprehensive, and difficult '. Second, the review of the planning materials is once every four years, and how much will happen to our computer technology in four years. Software and Hardware technologies have been eliminated and updated several generations, while students are still using old teaching materials. Even if they have chosen a set of excellent learning materials, can they be guaranteed in the future ?"

To change this situation, Tan haoqiang The professor did not even review his work, but did not enter 《CLanguageProgramThe sales volume of design has reached more than 70 million. In this regard, Tan haoqiang Professor believes: "choosing teaching materials is ultimately a kind of market behavior. The majority of teachers and students have the most say as consumers. They will decide whether to vote for you through purchasing materials ."

The third factor is that some publishers write books for teachers in the school for their own benefit, and then use the relationship between the schools to promote these textbooks in these schools. Tan haoqiang The professor gave an example: "educational institutions in many provinces require non-computer students in the province to choose textbooks for the Computer Level examination. Because of the relationship between questions, students who use unified textbooks can pass the examination only if the scope of the examination is within the unified textbooks. Otherwise, they may not pass the examination. However, in this way, if these textbooks are of excellent quality, this is a great fortune for the majority of students. If the quality is poor, it is not only a wrong behavior, but for excellent textbooks, this is an action to drive bad coins."

 

"Understanding" Computer Education

Ask for advice on the question of "What kind of teaching material is a good teaching material" Yu tan haoqiang When teaching, he gave the answer: "excellent teaching materials should meet the requirements of accurate positioning, advanced content, reasonable choice, proper system, and excellent style. The core must be people-oriented ."

There are several simple requirements, but they are a bit difficult to implement. Many textbooks and books strive to be big and complete, making it hard to tell whether they are teaching materials or technical manuals. Some textbooks are difficult to improve, and it does not seem to show the level of the author. Following this idea, Many Even the following graduate students cannot understand their lectures.70%Is proud of the content. But how can we achieve the purpose of preaching, teaching, and confusing.

In accordance with the requirements of excellent teaching materials, Tan haoqiang The authors of the teaching materials should have a high degree of responsibility, be capable of positioning readers, understand the rules of understanding, make full use of image thinking, and be able to think differently frequently, in addition, we must grasp the principle that it is easier for students to learn their own books.

These points also seem to be difficult for the textbook authors. Tan haoqiang The professor gave an example: "For exampleCThe delivery rules in the language, the previous textbooks and reference books all avoided the detailed explanation of this part of content, and kept the questions for the students to understand themselves, so that the students' learning will not be a problem for the students. As a matter of fact, students cannot learn it. The teacher should first look for reasons from himself to see how your teaching material is compiled and how your class is said ."

Tan haoqiang Professor added: "The Two-dimensional array pointer isCI want to use image thinking to give an example of a difficult problem in language. For this reason, I thought about it for three days and three nights and finally came up with an example: There are three classes in a row, if the class leader is regarded as a pointer, the responsibility of the class leader is to ensure that everyone in his class is in his position, and the pointer of the class leader points to everyone in the class; the role of the platoon leader is to check whether three classes have been completed. Therefore, the shift leader points to the shift leader. The students suddenly understood it. 《CThe language tutorial can sell 70 million books, and my secret is "Understanding", just like a clear Hua Lao The professor said: A really competent teacher is a teacher who can tell the most difficult content in the most easy-to-understand and popular way ."

Tan haoqiang Professor believes: "It seems nothing to understand a word, but the effect on textbooks is quite different. For 《C ++I have read more100BenC ++But I can't really understand some books, because these books often use another unintelligible term to explain a noun. Obviously, the translator himself did not understand what the word meant. For example, it is easier for students to learn this item by themselves. Foreign practices are lecture 1, study 2, and test 3. In turn, the practice in China is lecture 1, Test 1, and test 1. If the teaching materials of computer science are easy to learn, the lesson can be used more on the computer, so that students have more opportunities to practice, and the level will naturally increase rapidly. In turn, it is difficult for the teacher to spend too much time explaining what students do not understand in the teaching materials, and the learning effect is naturally poor ."

 

Who is eligible to compile computer textbooks?

At present, there are not a few teachers who have compiled teaching materials in colleges and universities across the country, or even almost all of them are involved. But when we go deep into every teaching material, when studying the teaching value of these teaching materials, we find that the results are not optimistic .. At least, these books must have deviated from the compiling goal of teaching materials. Even many authors have never considered this issue before writing teaching materials. When we ask for advice on this issue Yu tan haoqiang When teaching, he came up with his own point of view: "Only excellent teachers can write good teaching materials. If they are not good teachers, they are not qualified to write teaching materials ."

Tan haoqiang Professor's 《CThe book language programming was first presented as a lecture for three years before being published, and was published only after being modified according to the student's response. As handouts, Tan haoqiang The professor fixes it every year, so that it has dozens of unpublished versions. On the contrary, a teacher in Beijing claimed that all computer books could be edited. when dozens of books were found, a new book was released. Because all the other books are copied into the book, this book is indeed correct, but as a teaching material, the value of its teaching is only available to heaven. Even more outrageous, another teacher, at the invitation of a book dealer, writes a bookWordIs the content of the book. Due to marketing needs, a new book has been created after a unit is removed and the pricing is cut off. As a result, a book becomes ten books, and on the counter, you can choose their books from low to high. However Tan haoqiang The professor said: "I must explain that the demand difference between readers at different levels is not only about the content and price, but also about their cognitive habits and acceptability, you must provide them with the appropriate content."

Professor Tan haoqiang finally stressed that, the computer level in China is already quite different from that in developed countries in Europe and America. If we do not pay attention to the improvement of teaching materials, teaching methods, and other links that affect the level of computer education, this gap will only increase. If this happens, Chinese students will not be able to learn computers.
