Specifically, it can be divided into several situations:
An old teacher who has been teaching for a long time, and the textbook has not changed for many years, teaches only those knowledge points, knows the contents of the textbook and the syllabus thoroughly, and knows what to test and what not to test. This situation is the most convenient. It may take ten minutes to prepare for a class. You just need to familiarize yourself with the content, improve the framework and make a little preparation, or slightly modify the PPT of previous years, which can basically be shaped, used as it is, and flexible in class.
Old teachers who have also been teaching for a long time, if the textbooks are newly replaced, it will take a long time to prepare lessons. After all, the textbooks keep pace with the times, and the updated contents may not be mastered by the old teachers, and it will take some time to get familiar with them. Sometimes it takes more time than young teachers who are exposed to new things. Of course, knowledge is flexible, and the characteristics of different disciplines are different. For example, the change of science is relatively small, and the replacement of teaching materials has little effect on old teachers.
For young teachers, it usually takes a long time to prepare lessons. After all, they are new to textbooks, and they still don't understand all aspects. They are still in the exploration stage and many things have not yet formed a system, so they need to spend more time dealing with all aspects. From the handling of the relationship between teachers and students in classroom teaching, the handling of important and difficult problems, to the handling of details of various knowledge points, we need to scrutinize and ponder carefully, and at the same time we need to consult more old teachers. Therefore, for novice teachers, sometimes it may take a long time to prepare a lesson, of course, if a lesson is well taught.
To prepare a lesson well, we usually need to prepare from three aspects: teaching content (preparing teaching materials), teaching object (preparing students) and teaching method (preparing teaching methods).
Teaching content. When preparing lessons, it is very important to prepare the course content. Carefully study the textbook, find out the important and difficult points of learning according to the curriculum standard, and prepare to grasp all the knowledge points. Prepare the content of a class, comb it completely, so that you can teach better and your children can learn better. You need to work hard and prepare carefully.
Teaching object. Students in different classes have different learning situations. Due to the cognitive differences, teachers need to prepare lessons according to the teaching objects when preparing courses, so that students can have better contact and learn better. As a teacher, we should understand the psychology of teaching objects and their cognitive level, so that children can learn better.
Teaching methods. As a teacher, the most important duty is to make the children they teach learn better and accept more naturally. Therefore, teachers should use the best teaching methods to guide the children to learn better. In the process of preparing lessons, teachers should sort out and summarize their own teaching methods, so as to get twice the result with half the effort.
