There are many forms of review, such as class review, unit review, final review, etc.

There are three types of classroom review: before teaching a new lesson, review the old knowledge related to it, which is called preparing for review; After the teacher finishes the lecture, he often has to do some exercises while the iron is hot, which is a preparatory review for the purpose of digestion; At the end of a lesson, the content learned in this section will be sorted out, summarized, and summarized, which is a combing review for the purpose of absorption.

Regardless of whether the teacher has homework or not, the teacher should review it in comparison with the class notes and the textbook before doing the homework.

Unit review refers to the review after completing a chapter or a group of contents, mainly by comparing similarities and differences, looking for internal connections, and screening and accumulation.

The final review is mainly a process of analyzing and synthesizing the knowledge that is usually scattered and classified.

In our study life, the most precious time is to review after class, because the most effective way to prevent forgetting is to review in time. Psychological research shows that memory is regular, and the knowledge learned will be forgotten if it is not reviewed, more than half of it will be forgotten after one day, and it will be forgotten about 2 3 after two days, and the number of forgotten will gradually decrease in the future. Therefore, if you do not review in time after studying, it will greatly increase the difficulty of revision and reduce the efficiency of learning.

In order to improve the efficiency of revision, we need to adopt certain methods when reviewing and make reasonable arrangements from different angles. In terms of timing, review after class should be arranged at least twice. The first time you use the break time to review the main points of the lesson with your brain, and the second review should be arranged in the evening, read the class notes, and compare them with the textbook.

In the use of revision methods, you can use them flexibly according to your actual situation.

Commonly used revision methods are:

1) Try recall. That is, when reviewing, first recall the content that the teacher has talked about in your mind, and then open the book or notebook for comparison, and then review the knowledge that is vague or cannot be recalled at all, which can not only strengthen the memory, but also gradually develop the habit of positive thinking;

2) Bullet point method. That is, in the process of review, seek the main points in the knowledge, and grasp the main points to grasp the backbone of the problem. For example, when reviewing the text, you can mark the key words, the key sentences of each paragraph, and the transition sentences that connect the previous and the next with eye-catching colors, so that these words and sentences can be used as the support point for memorization, and grasp a few key words and sentences, which will also grasp the content of the whole text;

3) Comparative Method. That is, to find out the characteristics and commonalities between the knowledge of each subject, and strengthen the review effect by seeking differences in the same or seeking common ground in differences.
