Educational problems. Pedagogy is a social science that studies educational phenomena, educational problems and their laws. The research content of pedagogy includes the essence, purpose, method and process of education, which is closely related to educational problems. Only by in-depth study of educational issues can we better understand the nature and laws of education and provide theoretical basis for the development of pedagogy. The development of educational problems has promoted the theoretical innovation of pedagogy. With the development and reform of society, educational problems are constantly changing and developing. The emergence of these new problems requires pedagogy to constantly innovate in theory to meet the new educational needs and challenges. For example, the development of modern information technology has brought new opportunities and challenges to education, and pedagogy also needs to constantly explore new teaching models and methods to adapt to this change. To sum up, the internal driving force to promote the development of pedagogy is the development of educational problems.
