The so-called "subject" is the subject of research and discussion. Furthermore, the so-called "subject" is the central concept of research thinking. One interpretation I appreciate is that the topic is a research platform that is problem-oriented, accumulates everyone's wisdom and generates sparks of thinking.

Reference for Selecting Topics in Primary School Mathematics Research

1, a practical study on the effective use of students' learning starting point

Research content: what is the starting point of students' learning, what are the different types of research on the starting point of learning in mathematics teaching, and how to find and effectively use the starting point of students' learning.

2. Pay attention to the practical research of students with learning difficulties in mathematics.

Research content: Make a case study of students with learning difficulties who have mastered mathematical concepts, calculation ability or weak problem-solving ability, how to give targeted counseling to students, and study the causes and countermeasures of "polarization" phenomenon.

3. Research on the homework design of basic investigation before primary school mathematics class.

4. Research on the optimization of students' mathematics learning process.

5. Research on the general strategies and key factors of mathematics concept teaching in primary schools: the general strategies and key factors of problem-solving teaching.

6. Research on the teaching strategy of combining "calculation" with "application": the design strategy of exercise class, the development and application of exercise questions, and the teaching research on the quantitative relationship in the teaching of application questions.

7. Research on the effectiveness of hands-on practice in mathematics teaching.

8. Research on Mathematics Appreciation Course

9. Research on oral arithmetic teaching under the background of new curriculum.
