Choosing a topic first, that is, choosing a special topic for research, is the first and important step in educational science research. Because the choice of questions not only specifies the direction and content of research, but also determines the methods and approaches that should be adopted in research work. So we must treat it with caution.

Secondly, form a hypothesis, that is, imagine the cause and effect or conclusion of the problem with research value according to the existing facts and materials. The function of hypothesis is that it is not only a directional imagination to be verified, but also affects the process organization, research logic and research method selection of research activities.

So once the hypothesis is formed, researchers can design and carry out a series of research activities in a planned way within a limited scope according to the determined goals. Therefore, hypothesis is the necessary stage of educational science research and exploration, and it is the correct way and effective means to accurately grasp the laws of education.

Introduction:

Research hypothesis is a speculative judgment and hypothetical explanation made by researchers on the laws or reasons of the research problems based on empirical facts and scientific theories. It is a tentative theory conceived in advance before the research.

Simply put, it is the temporary answer to the research question. Mainly divided into: descriptive hypothesis, explanatory hypothesis, predictive hypothesis and content hypothesis. Research hypothesis is a statement that can verify the truth and falsehood, which is generally used in relatively standardized confirmatory quantitative research.
