The reasons why the educational research of primary and secondary school teachers should focus on applied research include the following aspects:

1, strong practicality: applied research focuses on solving practical problems and combines theoretical knowledge with practical experience, which is closer to primary and secondary education scenes and more practical.

2. Clear objectives: Applied research focuses on solving practical problems and improving the effect of educational practice. The goal is specific, clear and targeted, which can effectively solve the specific problems encountered in the practice of primary and secondary education.

3. Strong promotion: Applied research can find out the problems and shortcomings in education and teaching in time, and realize the continuous improvement and improvement of education and teaching by improving and optimizing the design and methods of education and teaching.

4. Strong operability: Applied research relies on practical activities and pays attention to the use of various practical means for data collection and analysis. The data results can be directly applied to education and teaching practice, forming instructive experiences and practices.

5. Strong popularization: The applied research results have strong popularization and reproducibility, and can be applied to other primary and secondary education practices in a targeted manner to promote the improvement and continuous development of education and teaching quality.

Primary and secondary school teachers should pay attention to the following matters:

1. Determine the research direction and objectives: Primary and secondary school teachers should make clear their research direction and objectives before starting scientific research, and combine them with actual teaching needs to ensure that the research is practical and instructive.

2. Collecting and analyzing data: When conducting scientific research, primary and secondary school teachers should pay attention to collecting and analyzing relevant data and follow scientific data collection and analysis methods to ensure the authenticity and reliability of data.

3. Accurately express research results: When writing research results, primary and secondary school teachers should accurately and clearly express their research results and avoid vague, vague or inaccurate expressions to ensure that research results meet scientific norms and academic requirements.

4. Be good at learning and cooperation: When conducting scientific research, primary and secondary school teachers should be good at learning from advanced experiences and practices and actively participate in various academic seminars, forums and other activities. At the same time, we can exchange and cooperate with our peers, learn from each other's strong points and jointly improve the level of scientific research.

5. Pay attention to practical application: When conducting scientific research, primary and secondary school teachers should pay attention to applying scientific research results to practical teaching and management, constantly optimize and improve the design and methods of education and teaching, and improve the quality and effect of education and teaching.
