Confucius said, "Review the past and learn the new". For example, ushinski, a Soviet educator, said: The review is not to repair collapsed buildings, but to strengthen the original structure and build new floors. Both educators mentioned a word "new" in their incisive words. It can be seen that review is not a simple mechanical exercise of old knowledge, but should be regarded as a more active, serious, profound and systematic learning process to understand and master knowledge and ability. .
First, grasp the foundation. -Don't neglect the induction and arrangement of basic knowledge.
As the saying goes, "how deep the foundation is, how many high walls will be built" and "the roots are deep and leafy". Only when the foundation is solid can a tall building be built. In order to improve the review class and make students gain something, we must follow one point: never leave their original religion, textbooks are the foundation, and grasping the foundation is the key.
Second, re-compare. -Don't ignore the internal connection of knowledge points.
Review is not a simple repetition of old knowledge. Teachers should actively guide students to consolidate knowledge, and at the same time pay attention to discovering the vertical and horizontal connections between knowledge. Through comparison, observation and discovery, it is found that isolated and scattered knowledge points are strung into lines, connected into pieces and networked.
As we all know, reviewing lessons is difficult. When a teacher takes a review class, he lists all the math knowledge he has learned and then practices them one by one. All the knowledge he has learned remains in the students' minds without a clue, and it is still chaotic after class. Only by connecting all knowledge points scientifically and orderly and combing them systematically can we form a small mathematical knowledge line, and then connect several small knowledge lines to expand into a large knowledge chain. This kind of review class will be effective.
Third, grasp the overall situation. Don't ignore the different needs of students.
/kloc-in the 0 th and 7 th centuries, Leibniz said a wise saying: "There are no two identical leaves in the world." So we have every reason to say that there are no two identical people in the world, and it is impossible to train two identical students. In the process of teaching, it is our responsibility to pay attention to teaching students in accordance with their aptitude and not to give up any students. This is especially true in the review class. However, how to embody "teaching students in accordance with their aptitude" has always been a difficult problem in exploration and research.
In practice, it is found that hierarchical teaching is an effective strategy to "let every child develop". Among them, teachers should be able to conduct hierarchical, hierarchical homework and hierarchical evaluation on students in some aspects of teaching. For example, in classroom questioning, we should use the content of conceptual memory to ask questions to poor students, train their expressive ability, teach them thinking methods, and gradually develop the habit of serious thinking; Topics that need careful consideration and moderate difficulty are reserved for middle-level students, so that they can taste the joy of success, stimulate interest and make progress; Students with better level should answer more questions about intelligence application, so as to broaden their knowledge and improve their ability. For another example, after reviewing the contents of the first volume of the sixth grade, the teacher can set up such layered homework.
The first-level questions need to be mastered by everyone, and the second-level questions need to be mastered by most students, and some students can solve them with the guidance and help of teachers. Problems at the third level should only be solved by students who have the spare capacity to study. In this way, different levels of homework are designed for students of different levels, and students get the joy of success in the selected homework. Correcting homework should also vary from person to person, and some students who are backward in learning should be praised and encouraged to comment. At the same time, we should objectively and concretely point out the existing problems.
In a word, sorting out and reviewing the learned mathematics knowledge is not only an important link in the process of mathematics teaching in primary schools, but also an important form for students to learn mathematics. Review class is not the end of knowledge, but a new beginning of some knowledge. How to have a good review class is a problem that we have to explore, and teachers must not ignore the status of review class.
