(B) the principle of innovation

The principle of innovation, also known as the principle of creation, means that educational research should strive to make a breakthrough in theory and improve in practice.

(4) Operating principles

The operational principle means that the conceptual terms used by researchers in educational research should have clear and operational semantic provisions for qualitative or quantitative investigation.

The principle of testability means that peer experts should be able to get the same or similar results if they re-study under the same research conditions and according to the same procedures and methods.

(6) Ethical principles

Ethical principle means that the methods adopted in the process of educational research must conform to the current moral ethics, and cannot infringe on the rights of the subjects or harm their physical and mental health.

(7) the principle of integrating theory with practice

The principle of integrating theory with practice means that in educational research, we must adhere to the principle of combining theory with practice, analyze reality with theory, verify theory with practice, and analyze specific problems in the activities of objective phenomena, so as to obtain a regular understanding that conforms to reality, which can be used as a guide for practical activities in related fields, and further test, correct and improve existing understanding in practical activities.
