Practice is the basic category of Marxist philosophy. Engels pointed out in Anti-Duhring: “Labor will be combined with education in socialist society”, which contains the teaching policy of combining theory with practice. Postgraduate course teaching should not only stay in the theoretical analysis and construction of classroom teaching, but also pay attention to the field exploration and experience summary of practical teaching, so as to enrich students’ emotional experience, exercise their practical ability, and form a strong resultant force combining teaching with learning, theory with practice. At present, the practical teaching of Psychology of Ideological and Political Education for postgraduates has many developmental difficulties, such as insufficient content, methods, evaluation and guarantee. In order to optimize the practical teaching of psychology in ideological and political education, we should enrich the content, expand the forms of practical teaching, and construct multiple evaluation system and perfect multiple guarantee mechanism.
