Blended Learning And Its Effect On Diversified Students Achievement Under The Background of Higher Vocational Enrollment Expansion

The successive higher education expansion policies in 2019 and 2020 have prompted adult social students to enter higher education institutions that were originally mainly full-time off-the-job. Given that the diversified student population after the expansion also assumes social roles, higher vocational education as academic education has both the implication of adult education. In view of the learning characteristics required by adult roles and the application of new digital technologies in education, blended learning becomes an important and necessary form of teaching and learning for the cultivation of diverse students. However, there are few studies on the impact of teaching behaviors on learning inputs and learning outcomes in blended learning environments, especially in the field of adult education. This study constructs a model of the effect of blended learning on teaching behavior-learning engagement-learning effectiveness for diverse students, and validates the theoretical model by conducting a questionnaire survey on 2,132 students enrolled in the blended learning environment. The results showed that both teachers' teaching behaviors and students' learning inputs positively influenced learning outcomes in a blended learning environment, and teachers' teaching attitudes, teaching preparation, and teaching contexts positively contributed to students' cognitive, affective, and behavioral inputs, respectively. In addition, the effects of teaching behaviors on the dimensions of learning engagement were more pronounced among diverse students with higher motivation and self-efficacy. In order to promote the blended learning model to play a greater role in the teaching practice of the expanded group, higher education institutions should clarify the interplay between teaching behaviors and learning engagement, make teachers design blended teaching based on and targeted, focus on the effective integration of blended teaching design and teaching strategies for precise implementation, optimize the blended learning experience by enhancing students' self-efficacy and learning motivation, and thus improve learning effectiveness. To promote a fruitful reform of talent cultivation in adult academic education.
