How to choose extracurricular tutoring books for mathematics (science)? There are many kinds of extracurricular tutoring books in Mr. Wang's bookstore, and slogans such as "knowledgeable person", "Unlocking the Secret" and "Teacher So-and-so reveals the secret for the first time" are all over the cover, which makes people feel at a loss. Every parent-teacher meeting, parents who care about their children's learning will ask me, "What kind of counseling book do you want first?" Indeed, this is not a question that can be answered clearly in one sentence. I chose 100 kinds of counseling books. According to my own experience, I will explain to you how to choose counseling materials. First, it should be targeted. (1) At present, there are versions of junior high school mathematics in China, such as People's Education Edition, People's Education Edition, New Curriculum Standard Edition, Suker Edition, China Normal University Edition and Beijing Curriculum Reform Edition. Aim for the local senior high school entrance examination. (2) Students with comprehensive basic knowledge can choose the national version. (2) There are not many books, but they are applicable and practical. Two books are enough. It goes without saying that students' time is limited, so it will be easy and pleasant to improve their learning efficiency. Tutorial books in all subjects are enough. One is basic exercises when they are beginners of new knowledge. The other is to improve the application of extended knowledge and questions according to their own situation. Third, considering the close combination with the local senior high school entrance examination, the publication time and version are generally selected within two years. The more reprints, the more complete the description. Fourth, judging the quality of books focuses on examples and exercises, not the explanation of answers. Focus on the guidance books with examples of key questions, and analyze the problem-solving ideas of such questions. A detailed answer is not necessarily good. 5. Ask the in-service teacher to recommend it. It seems unrealistic for school teachers to recommend counseling books to each student alone, but what school teachers who know the requirements of senior high school entrance examination and students' learning level need most is counseling books for preparing lessons and assigning homework. So parents can ask the teacher. 6. Don't choose blindly. Don't be confused by the title; Don't be misled by the recommendation of the bookstore clerk, because that clerk may be a promoter of a publishing house.
