China's educational psychology was originally introduced from the west. Herbart is the first scholar who clearly put forward that psychology is the theoretical basis of pedagogy. 1806 published the book General Pedagogy. This book attempts to explain some problems of education, especially the theoretical problems of teaching, from the perspective of psychology. 1835, he wrote the outline of pedagogy, which supplemented and developed a series of educational psychology thoughts mentioned in the previous book. Herbart's attempt to combine psychology with education greatly promoted the emergence of educational psychology.
