The practical background is generally written as: why social practice is carried out, what environment the content or theme is in, what situation it faces, what contradictions and problems exist, what purpose is achieved through practice, and what significance is produced.

For example, in daily classroom teaching, I found that students either have no clear structure about the learning content of a semester or a unit, and often "monkeys break corn and throw one away", or wait for the teacher to tell them that this is a passive "spoon-feeding" learning input. Therefore, in order to improve students' thinking ability, I intend to try to apply mind mapping as a learning tool to mathematics teaching practice.

Working principle of social practice

1, adhere to the education-oriented principle, firmly establish the concept of practical education, and take improving the ideological and political quality of college students as the primary task.

2. Insist on integrating theory with practice to improve the pertinence, effectiveness and appeal of social practice.

3. Insist on the combination of in-class and out-of-class, and the combination of centralization and decentralization to ensure that every college student can participate in social practice and ensure that ideological and political education runs through the whole process of social practice.

4. Insist on education-oriented, talent-oriented and contribution-oriented to ensure the long-term healthy development of college students' social practice.

5. Insist on integrating resources, mobilize the enthusiasm of all parties inside and outside the school, and strive to form a good situation in which the whole society supports college students' social practice.
