As a goal for reform and innovation and a quality evaluation index for ideological and political theory courses, "sense of gain" has become the focus of teaching practice and teaching research with political theory courses. The current studies on sense of gain from political theory courses in academic circles focuses mainly on its implications, generation, influencing factors, and promotion approaches. Generally, the studies continue to widen and deepen, but there are still problems such as indeterminate connotations, indiscriminate similar concepts, imbalanced research subjects, and lack of sufficient studies and investigations. We should further clarify relevant concepts, care about ideological and political teachers' sense of gains, and promote empirical studies, so as to enrich and improve relevant investigation systems.
