In this paper, teachers try to skillfully integrate the knowledge points of the theoretical course into the experimental teaching in the course of innovative experiment of polymer material synthesis. By setting up the experimental section purposely, teachers can help the students consolidate the knowledge points of the theoretical course through the analysis of the experimental phenomena. In order to make full use of the spare time of the experiment, on the basis of organizing students to prepare for the experiment, a teaching mode, "encourage students to participate", is implemented, which can encourage students to explain the theoretical knowledge related to the experiment in the form of experimental groups, further consolidate and expand the relevant knowledge points. After two rounds of teaching, it shows that these attempts have not only effectively consolidated the theoretical classroom knowledge points, achieved a lively use of learning, but also stimulated students' interests in learning, and improved the ability to analyze problems.

The continuation and coordination between basic chemistry and specialty chemistry are usually critical problems during the chemistry teaching. This paper classified the complex basic knowledge and professional theory as specific learning objectives; and the course content was reorganized accordingly. The PBL mode was defined as teaching method to enhance the self-management and problem solving abilities in the learning process. The CBL mode was employed for case analysis. The abstract and boring theoretical knowledge was turned into intuitive and vivid cases, which prompted students to constantly think about the reason and mechanism of this problem or phenomenon, overcoming the deficiency of the mutual separation between ordinary teaching theory and practice. Such teaching methods combine reason-result, point-face and abstract-concrete perspectives to emphasize key knowledge points. The results of the surveys show better efficiency for encourage and motivation of students and thus improve their examine results.
