(1) Derive research questions from relevant theories;

From the development of educational theory, we should not only reveal the contradiction between the original theory and empirical facts, but also reveal the logical contradiction within the theory; It includes not only some unknown research topics in the planning and construction of discipline system, but also the criticism and questioning of the traditional concepts and conclusions of existing educational theories, as well as the problems raised in academic debates.

(2) Problems found in educational practice:

Solve the urgent needs of social practice. This is the direct source. For example, The Charm of Ancient Trees in Beijing is a special gift for the 29th Beijing Green Olympics.

(3) Problems found in previous studies:

By consulting the literature, we can understand the latest achievements in the research field and the development trend and frontier of related disciplines, and dig up topics. This is an indirect source.

By consulting a large number of documents, that is, deriving, extending and sublimating from the theoretical summary of predecessors, we can select topics with high value that can enrich, improve and even fill the gaps. For example, the publishing project of China Forest Ecological Network System Engineering Construction Series is the integration of a series of research results such as China Forest Ecological Network System Engineering Construction.

(4) Problems found in contact with professionals:

In the process of educational practice, researchers should not only look for the internal relationship between rich educational and teaching experience and facts, but also reveal its internal regularity; We should also find problems from argumentation, improve our sensitivity to educational problems and consciously cultivate educational wisdom. Only in this way can we constantly discover and pay attention to problems in practice.

Principles of scientific research topic selection:

(1) principle of necessity

The principle of necessity means that the topic should face reality, pay attention to social needs and stress social benefits. This is the first and basic principle of topic selection, which embodies the purpose of scientific research, that is, the purpose principle. The so-called needs here include two aspects: first, according to the needs of social practice, especially the needs of industrial and agricultural production, this is its social significance; Second, according to the needs of the development of science itself, this is its academic significance. Or both.

(2) the principle of feasibility

The principle of feasibility means to consider the realistic possibility when choosing a topic. The principle of feasibility embodies the "conditional principle" of scientific research. The selection of topics must proceed from the subjective and objective conditions of researchers and choose topics that are conducive to development. If a subject does not have the necessary conditions, no matter how much the society needs, how advanced and how scientific it is, it is impossible to achieve it, and the topic selection is equal to zero.

(3) the principle of rationality

The principle of rationality means that the topic selection should not only meet the needs of social and scientific development, but also have practical value; Really feasible; It depends on whether the topic itself is reasonable. The so-called rationality principle is also called scientific principle. For example, perpetual motion machine, turning water into oil, is always in vain.
