Choosing fair teaching content is the condition of preparing lessons. The choice of teaching content should be based on the characteristics of knowledge, the intention of compiling teaching materials, the time required to complete teaching tasks and the actual situation of students. How to reasonably choose the teaching content of a class? The first is to choose according to the arrangement of teaching materials. Usually we divide the knowledge of an exercise into several small paragraphs, and each small paragraph is the teaching content of a class. Today's mathematics textbooks are all arranged in this way. When preparing lessons, teachers can determine the teaching content of a class just by looking at the newly taught content and corresponding exercises in the textbook. The second is to choose according to the difficulty of knowledge. Generally speaking, students can choose more relatively simple knowledge content that is easy to accept and understand; For the knowledge that is difficult for students to understand and master, because more time is spent in teaching, the content selection should be less appropriately. When choosing the teaching content of a class, we should treat it according to the specific situation. A class can successfully complete the teaching task, and the knowledge taught is conducive to students' understanding and mastery.
2. The goal should be set correctly.
The correct goal means that the teaching goal should not only meet the requirements of curriculum standards, but also meet the actual situation of students. Teaching goal is the basis of designing teaching process, the general guiding ideology of classroom teaching, and the starting point and final destination of classroom teaching. How to make a concrete and feasible teaching goal? First of all, we should carefully study the teaching materials, combine the objectives and teaching contents of the mathematics course, and work out the teaching plan of this lesson: what knowledge students should master, what skills they should form, what proficiency they should achieve, and what methods to solve problems. This is the double-base target. Secondly, we should consider what kind of thinking ability students can cultivate through the teaching of this knowledge, which is the goal of thinking ability. Thirdly, through imparting this knowledge, we should think about what kind of ideological education and good moral quality students should have, which is the requirement of infiltrating ideological education. Finally, we should consider where students can receive innovative education and how to cultivate their innovative consciousness and creativity. This is the requirement of innovative education and the most important goal of classroom teaching.
3. We should grasp the key points and difficulties.
The teaching of key and difficult points is the key to a class, and the level of teachers' classroom teaching is mainly reflected in the prominence of key points and the breakthrough of difficult points. Generally speaking, the main knowledge that students should master in a class is the teaching focus of this class, and the difficulty of students' understanding and acceptance is the teaching difficulty. How to highlight key points and break through difficulties in classroom teaching? First of all, teachers must grasp the key points and difficulties. When the teaching content is determined, teachers should seriously consider: what knowledge can students understand and master through teaching, and the main and key knowledge is the focus of teaching; What difficulties students will encounter in learning, and the knowledge that students are difficult to understand and easy to make mistakes are the difficulties in teaching. Secondly, consider how to highlight key points and break through difficulties. When the key points and difficulties are determined, teachers should also consider: how to link teaching with students' familiar life? How to connect with students' existing knowledge? Finally, specific and feasible teaching plans are worked out to help students make things easier and understand and master what they have learned.
4. You should know the level of students.
New knowledge is developed, changed and extended on the basis of old knowledge. Therefore, when preparing lessons, teachers should find out the old knowledge related to the new knowledge according to the content of their own knowledge, see what knowledge students have mastered and what knowledge they have not fully mastered, determine which knowledge loopholes students need to fill, arrange what review content before class, and choose which learning methods and teaching methods for new teachers. This is what we often say about preparing students' knowledge level. Only in this way, we are preparing lessons.
5. Learning methods should be appropriate
Students' learning method is an important aspect of classroom teaching, which can not only reflect teachers' teaching ideas, but also affect students' classroom learning effect and the realization of new curriculum goals. How to choose students' learning methods? First of all, it should be suitable and conform to the actual situation of students; Secondly, it should help students understand and master knowledge; Third, it is conducive to the formation of students' innovative consciousness and the development of innovative ability.
