Step 1: Read

That is, reading books, texts, intensive reading, repeated recitation and in-depth understanding.

Step 2: Rowing

It is to mark with various symbols to help analyze and summarize, such as sketching out definitions, theorems, important and difficult points, sketching, eyebrows, asking questions ... You can use different symbols such as horizontal lines, wavy lines, question marks, exclamation points and arrows, and pay attention to the consistency of symbols.

Difficult problems encountered in reading and data that must be understood can be clarified by consulting other materials, or verified by reference books, so as to leave no problems or fewer problems after self-examination.

Step 4: Think.

Just think and ask more questions about the material you read. Why? From the introduction method to the connotation and extension of the concept, from the method of proving the problem to the basis of proving the problem, we should think and answer one by one according to the thinking questions sorted out by books or teachers, and further master them in understanding.

Step 5: Compare

The significance of comparison, on the one hand, is to compare reading vertically and horizontally, find out the similarities, similarities and differences between this knowledge and related knowledge, and bring it into the corresponding knowledge chain; On the other hand, it is compared with the narrative methods of books of the same category and content, so as to be familiar with its characteristics and strengthen the memory of the structure.

Step 6: Practice

Writing and doing, whether the concept is clear and accurate, whether the method is mastered and whether the skills are available, must be tested through practice. This is a good way to test the reading effect and train the reproduction thinking. These methods will stimulate the concentration and depth of reading, and create conditions for further improving reproduction ability and enhancing consciousness.
