A systematic and integrated experiment including “polycrystalline powder synthesis→phase analysis →crystal growth→material characterization” was established to improve the students' comprehensive and analytical ability. The basic knowledge of crystallography was involved during practical crystal growth process. On one hand, the effect of crystal growth dynamics factors (such as supersaturation, temperature and material diffusion) on crystal growth habits and morphology can be interpreted more deeply. On the other hand, the students can learn some important methods of material characterization. Moreover, the basic theory of crystal structure can be mastered. Importantly, the capability of applying theoretical knowledge to practice was improved and a research approach with systematic science principle can be learned through this experiment at last.

In this paper, the cutting edge result was introduced into the comprehensive experiment in organic chemistry. We designed a comprehensive experiment on the synthesis, characterization and properties of BINOL-based chiral compound with aggregation-induced emission characteristics. Based on this experiment, the students will learn several basic organic transformations, such as protection of phenol hydroxyl groups, formylation and condensation reactions. Meanwhile, they will characterize the chemical structure of this chiral compound by using nuclear magnetic resonance and mass spectroscopies, and investigate its optical properties by employing UV-Vis, emission and circular dichroism spectroscopies. This experiment will help students to have a better understanding about the phenomenon and mechanism of aggregation-induced emission. This experiment combined various organic reactions and characterization methods, which is conducive to systematically improving the experimental ability, scientific research ability and inspiring the interests in scientific research of students.

This paper outlines the application of the multi-dimensional classroom teaching mode and the example-oriented research-based teaching design in the colloidal dispersion section of the medical basic chemistry course. For our university, this part will be described from the beginning of the first semester, so this part of the content is more difficult for the students who do not have the perfect self-learning ability. Therefore, we designed a variety of examples that are closely related to medical content and contain the important concepts in this chapter, at the same time, we selected some knowledge points and invited clinical department teachers to record the micro-classes, and show these two parts to students at the appropriate time. The results show that this combined teaching mode helps to increase students' interest in learning and mobilize their concentration of learning, and they master the core chapter concepts and knowledge within a limited period of time, which will lay a solid foundation for the subsequent study of physical chemistry and inorganic chemistry.

The environmental chemistry course plays an important role in improving students' understanding of environmental pollution and practical ability of pollution control. The “trinity” course objectives was reconstructed based on curriculum ideology and politics. According to the characteristics of the course content, the ideological and political points were excavated based on various aspects, including the cultivation of the correct view of environment and environmental pollution, the scientific literacy establishment of analyzing and solving problem correctly, the formation of good environmental protection habits, and so on. A comprehensive organic integration system of ideological and political elements and course teaching was then constructed in detail. Also, a three-dimensional teaching model was build via the drip irrigation infiltration of the ideological and political elements. The analysis results of practice effect suggested that the organic integration and accurate docking of ideological and political connotation in the teaching of environmental chemistry could be achieved according to the teaching design with the obvious ideological and political characteristics. The same frequency resonance of ability improvement and value building could be improved in the student-centered flipped classroom. The students' sense of learning gain and literacy ability have been greatly improved, so as the integrated learning goal of “accomplishment + ability +knowledge” have been realized well. Among them, teachers' scientific research feed-back teaching can trigger students' enthusiasm for learning and willingness to expand practice. Therefore, in the course ideological and political education, we should fully pay attention to the example effect of teachers around us on students.
