The main viewpoint of experimental pedagogy is to study education with scientific methods, attach importance to quantitative data, emphasize experiment and observation, and be pragmatic.

1. Studying education by scientific methods: Experimental pedagogy firmly believes that education is a kind of science, and we can systematically observe, measure and experiment through experimental methods, so as to draw reliable conclusions. This scientific method can be used to study various phenomena in education, including students' learning process, teachers' teaching methods and school management models.

2. Attach importance to quantitative data: Experimental pedagogy emphasizes studying educational phenomena through quantitative data and describing and explaining educational problems in a digital way. Quantitative data can provide objective and accurate evidence to help us better understand and solve educational problems.

3. Pay attention to experiment and observation: Experimental pedagogy thinks that educational phenomena can be studied through experiment and observation. Experiment is a process of controlling specific conditions and observing them to determine the relationship between various factors. Observation is a direct record and description of various educational phenomena such as students, teachers and schools.

4. Pragmatic orientation: Experimental pedagogy emphasizes the practicality and operability of research results and advocates applying research results to practical educational practice. Therefore, the research results of experimental pedagogy are usually specific solutions and methods for specific educational problems.

The main application fields of experimental pedagogy:

1. Curriculum and teaching design: Experimental pedagogy can be used to design and evaluate courses and formulate more effective teaching strategies. Through experiments and research, educators can determine which teaching methods and course contents are more conducive to students' learning and development.

2. Evaluate and improve the education system: Experimental pedagogy can be used to evaluate and improve the whole education system. For example, by comparing the educational practices of different schools and regions, we can know which educational policies and practices are effective and which need to be improved.

3. Evaluate students' development: Experimental pedagogy can be used to evaluate students' development process, so as to better understand their learning needs and provide personalized teaching services.

4. Understand the development of teachers: Experimental pedagogy can also be used to understand the development process of teachers, thus providing better opportunities for teachers' training and development.

5. Interdisciplinary research: Experimental pedagogy can be combined with psychology, neuroscience and other disciplines to jointly study educational problems, thus providing a more comprehensive solution.
