"Didn't understand or not fully understand" is the most common situation that students experience when they learn medical biochemistry and molecular biology (MBMB). Therefore, the primary task of teaching MBMB is to help students overcome the difficulties in "conceptual understanding." The core of the solution to these problems lies in the acquisition and application of cognitive skills. The key to applying Ausubel cognitive assimilation theory (A's CAT) is to expand the knowledge capacity of students' cognitive structure through the purposeful "production" and employment of advanced organizers, with which students can replace "rote learning" with "meaningful learning" and ultimately develop an interest in MBMB courses. The results showed that the application of A's CAT did not only encourage the students to use cognitive skills to learn and understand MBMB knowledge and overcome the barrier to learning that results from the characteristics of the MBMB course, but also expanded and deepened the MBMB course contents. As a branch of learning theory, A's CAT provides practical methods for the several hypotheses of learning theory. Among these, the advanced organizer strategy realizes the organization and reorganization of new knowledge; the progressive differentiation strategy reduces the difficulty of complex and abstract knowledge; the implementation of the advanced organizer strategy and integrative reconciliation strategy forms the concept map. Taken together, the application of A's CAT includes cognitive strategy and metacognitive strategy when the cognitive process is conducted in a meaningful way. More importantly, application of A's CAT guides students to participate in active learning and builds "scaffolding" for the teaching/learning MBMB of student-centered goals.
