The Nobel Prize in chemistry 2013 was awarded jointly to three American chemists Martin Karplus, Michel Levitt and Arieh Warshel for the development of multiscale model for complex chemical systems. On the basis of many scientists' work, they combined quantum physics with classical physics and developed the multiscale model in which quantum physics is used in dealing with the heart of molecular structure or chemical reaction, while classical physics is used in the treatments of ambient matters or the environment, and dielectric model is used in the outermost layers. With the help of this model, theoretical calculations of the complex process of chemical reaction, heterogeneous catalysis and spectrum of molecules in solutions can be done by computer programming.

Chaoshan Kungfu tea contains rich chemical culture. For a long time, in the breeding, planting, processing and tasting of Fenghuang Dancong tea, the people of Chaoshan paid close attention to the chemical substances including catechins, theanine, caffeine, soluble sugars, pigments and terpenoids etc, which affect the quality and flavor of tea, finely controlled the quantity and biochemical transformation of these chemical substances in production and processing in order to create unique quality and flavor, and explored a set of scientific brewing program according to the compositions of active components in tea. The culture of Chaoshan Kungfu tea fully showed wisdom of chemistry.

Analytical chemistry curriculum reform and especially the development of analytical chemistry textbooks are studied from the perspective of textbook publishers. The development of analytical chemistry textbooks experienced embryonic period, development period and mature period. The characteristics and changes of form and content of typical analytical chemistry textbooks in different periods are elaborated, and the developing trends are discussed.

The orientation of applied chemistry specialty in new undergraduate college should train professional personnel engaged in work of technical development at chemical industry and related enterprises. The curriculum system of applied chemistry specialty consists of foundation courses, core courses, specialty oriented courses, practical courses and extended courses.

Based on the characteristics of polymer subject in our university, the student research project which have been carried out for more than 10 years was integrated into the teaching of polymer chemistry, in order to stimulate students' interest of study and research, and make students study actively by design, experiment and summary of fresh cases.

A comprehensive instrumental experiment of the synthesis and characterization of silver nanoparticles was introduced. Silver nanoparticles was synthesized by chemical reduction and characterized using TEM and Uv-Vis techniques. The effect of volume ratio of reducing agent and silver nitrate on optical properties of silver nanoparticles and the relationship between concentration and absorbance of silver nanoparticles solution were examined. This experiment covers many basic experimental skills such as synthesis and instrumental characterization, with simple operating steps and direct characterization methods, so it is easy for students to learn.

Polyaluminum chloride was prepared at room temperature by an improved method, whose preparation method and effect of water purification are better than experiment approach in textbook.

Countermeasures of teaching content, teaching hours and assessment methods in chemical experiment teaching for elementary education major are given to satisfy modern demand based on analysis of current situation.

Using Problem-based learning(PBL)mode in classroom teaching of analytical chemistry for pharmacy major is helpful to improve students' abilities of finding problems, analyzing problems and solving actual problems.PBL mode can be used in the reform of teaching content and classroom teaching methods, combining with multimedia, internet and CAI, which will be benefit to promote the reform of classroom teaching of analytical chemistry, and train pharmacy major students with innovative ability.

Advantages and methods of application of simulation software in analytical chemistry teaching were elaborated by teaching examples. Combining simulation software with modern educational technology can visualize the abstract concepts in analytical chemistry, make atmosphere of classroom active, stimulate learning interests of students, cultivate comprehensive ability of students, and improve teaching quality. It is a new idea for analytical chemistry teaching.

Energy is a core concept of science education and also a hot topic in international science education research in recent years. On the basis of Liu Xiufeng and Wilson's study, a cognitive model of the energy concept was constructed. Combining with the related energy concepts existed in physics, chemistry and biology textbooks for high school and university in China, the questionnaire was designed to test and interview 280 Beijing normal university students major in physics, chemistry and biology. By Rasch model and SPSS data analysis, we found that different discipline background affects students' understanding level and perspectives of energy concepts, and there were some misconceptions. Finally, we established a cognitive progression of energy concepts based on cognitive difficulties, and gave some proposals for the teaching of energy concept.
