1. According to the depth of research, it can be divided into descriptive topics, causal topics and predictive topics. (1) Descriptive topic refers to a detailed description of the real situation of social phenomena, which is the most basic topic with low difficulty and low level. (2) Causality question refers to revealing the causal relationship between two or more social phenomena, and mainly answers "why" and "how to do it", which is of high level and difficult. (3) Predictive topic refers to predicting the future development trend and situation of things on the basis of clarifying the causal relationship of social phenomena. The research level is the highest, which is of great significance to practical work and theoretical research.
2. According to the size of the subject, it can be divided into macro subject, meso subject and micro subject. (1) The macro topic involves a wide range of specimen problems that need to be solved in a certain period of time, such as quality education. (2) The meso-discipline focuses on stage issues and local issues, and the scope of research is relatively small. (3) Micro-topics refer to topics with very specific research objects and limited coverage.
3. According to the research level, it can be divided into general topics, major topics and key topics. (1) The general project is aimed at most researchers, which is also called free application project. (2) Major projects are few and precise, with clear objectives, which are of great scientific significance and have very high requirements for project organizers and undertakers. (3) Key topics are established through in-depth research on the most urgent and important problems in the development and layout of disciplines and the growth points of new disciplines and new fields.
4. According to the research purpose, it can be divided into theoretical topics and applied topics. The former aims to reveal the essence of social phenomena and its development law; The latter aims to put forward specific plans or countermeasures to solve social practice problems. When a discipline has two purposes, it can be regarded as both a comprehensive discipline and a theoretical application discipline. There are four kinds of research study topics: (1) knowledge inquiry type. This is the lowest level in the research topic. Students learn a certain knowledge, broaden their learning scope under the guidance of teachers, gain learning experience, and even form a learning report. This kind of study and research, although only preliminary, is undoubtedly a brand-new starting point to stimulate students to study and research in a larger scope and degree. (2) Academic research type. In the study of arts and sciences, students have a strong interest in a certain teaching content, so as to determine the subject, find a tutor to give guidance, and spend weeks, months or even years researching and writing academic papers. (3) Social investigation. Going to society and life is a very gratifying phenomenon after the school opened the "research learning" class. Students investigate the society and then write a survey report. (4) create an inventive type. In the process of students' "research study", the highest research level should belong to scientific and technological innovation and invention. Through their own efforts, students made a serious attempt at scientific and technological invention with the goal of scientific and technological creation, and achieved results. Then apply it to society and create society.
