The history of subject education is an important branch of educational history and also an important branch of subject educology. It is a science that studies the history of the emergence and development of education and teaching in a certain subject, reveals the objective laws formed in the process of its occurrence and development, and predicts its future development trend. The  history of subject education is the intersection of multiple disciplines, involving education, subject educology, history, educational history, etc. Its ideal group of researchers should be a perfect combination of subject educology researchers and educational history researchers. The history of subject education poses a challenge to traditional research on educational history, especially in terms of research fields and methods. The current research status of the history of subject education in China mainly manifests in uneven development, lack of systematic and holistic content structure, single research methods, neglect of the study of the history of subject education ideology, and neglect of the study of students and teachers. Vigorously conducting research on the history of subject education has at least the following significance: opening up new fields of research in the history of education; Building the theoretical foundation of subject educology; Enriching the knowledge curriculum of teacher education; Clarifying the historical context of the development of subject education; Adapting to the training mechanism of professional graduate students.
