Action design research is really a paper. But also a research topic of a separate subject. As a technical term and research type, actionresearch began to appear in American social science research in 1940s, and was applied to educational research in 1950s. Since 1970s, it has been more and more welcomed by educational researchers, and now it has become the main way for educators to engage in educational research. (1) Basic concepts of action research For a long time, people have always regarded "action" and "research" as concepts in two different fields. "Action" refers to the practical work and activities of practitioners and practitioners; "Research" mainly refers to the discussion of human social activities and social sciences by specially trained professional workers, scholars and experts. "Action" and "research" are two different concepts, which are used to indicate that different people are engaged in different activities. In the field of educational research, action and research have been separated for a long time. Many educational researchers have chosen subjects that are seriously divorced from the practical needs of educational technology, and they have to extend the "achievements" of their research to the practical work of education. This makes it difficult for teachers and educational administrators in the front line of education to accept this. Teachers in the front line of education are rich in knowledge and have accumulated a lot of experience in practice. In fact, they can provide educational researchers with a lot of practical problems and inexhaustible research topics. Therefore, let them participate in educational research, make them become researchers of their own actual situation, improve their educational theory level, and effectively apply the research results to their own practical work. Educational researchers are not authoritative guides, but should go deep into the front line of education, cooperate with front-line teachers to carry out research, assume the responsibility of solving practical problems, and overcome the defects based on research assumptions. (2) Characteristics of action research; 1. Research purpose-focusing on solving problems encountered in practice; 1. Research situation; 2. Research object-practitioners; 3. Application of research; 3. The research process of action researchers; 3. Pay attention to cooperation; 3. solve the problem; 3. The result of inference is immediately applicable. According to ⒑' s research methods-human development, self-reflection and self-education-there are both quantitative and qualitative methods, as well as qualitative research, some scholars summarize action research into three main characteristics: research for action; Action research; The study of actors. Action research points out the purpose of action research. The purpose of the research is not to establish a systematic academic theory, but to solve the problems encountered by practitioners in their situation. The research purpose is practical. The solution to the problem is direct. 2. Research is in action. Action research points out the research situation and methods. The environment of action research is the working situation of actual workers, not a specially arranged or controlled scene. The verification process of action research is the process of practical workers solving problems, the performance of actions, and the process of practical workers learning to reflect, explore and solve problems. 3. Actor research points out that the main body of action research is practitioners, not foreign experts and scholars. The role of experts and scholars involved in the research is to provide advice and consultation. It is a collaborator, not a research object. (III) Mode of Action Research Many scholars have given different definitions of action research and expounded it from different angles. At the same time, they also put forward many operation modes of action research. The following are some influential operation modes: 1. Lei Wen's spiral circulation model is an important pioneer of Lei Wen's action research. He not only put forward the terms and methods of action research for the first time, but also put forward that action research includes four links: planning, action, observation and reflection.
