Educational psychology is a social psychology that studies human learning, the effect of educational intervention, teaching psychology and school organization under the educational situation. The focus of educational psychology is to apply psychological theory or research results to education. Educational psychology can be used to design courses, improve teaching methods, promote learning motivation and help students face various difficulties and challenges in their growth. The terms "educational psychology" and "school psychology" are often used interchangeably, but people who usually engage in theoretical work and research are often called educational psychologists, while those who engage in practical work in schools or school-related fields are classified as school psychologists. Educational psychology pays attention to students' learning and development, especially to students with special educational needs (whether gifted children or children with emotional and behavioral problems) in practice. Through the relationship with other disciplines, it is also helpful to understand educational psychology. First of all, educational psychology is based on psychology, and the relationship between the two disciplines is like the relationship between medicine and biology, or the relationship between engineering and physics. From the perspective of educational psychology, many specialized fields can be developed to study educational problems, including teaching design, educational technology, curriculum development, organizational learning, special education, classroom management and so on. Educational psychology obtains nutrients from cognitive science and learning science, but it also reacts to these disciplines. In universities, the major of educational psychology is usually located in the department of education, which may be due to the lack of educational psychology in the teaching materials of introduction to psychology.
