Information technology in education has triggered a change in “psychology” learning, and dual-line integrated learning will become an important form of learning in the future. The impact of information technology on education has led to changes in psychological learning, and dual-line integrated learning will become a crucial form of learning in the future. Then, based on the FuzzyCDF model of fuzzy set theory, the students’ psychology cognition, learning ability, and knowledge mastery were tested to assess the student’s cognitive level and learning effectiveness of psychology courses. Then, we analyzed the effect of dual-line integration teaching, evaluated the teaching recognition and cognition of students in different grades, and explored in depth the effects of online and offline integration teaching on students’ learning attitude, learning anxiety, self-efficacy, and academic performance. Comparative analysis was used to analyze the impact of psychology course education on students’ mental health. The results showed that the student’s recognition of the dual-line integration learning mode was all above 3.7, the correlation of the online and offline learning mode on the dimensions of students’ learning attitude, self-efficacy, and academic achievement were all between (0.12,0.65), and the negative correlation on students’ learning anxiety. Psychoeducators in colleges and universities can benefit from this study in developing effective teaching strategies and improving the quality of psychology courses for college students.
