This paper discussed and reflected moduling experiment of organic chemistry for this Top Talent Training Program, including experiment objectives, moduling experiment design, conduct of moduling experiment, lessons and prospects.

This paper summarized our practices on cultural construction in chemistry laboratory including laboratory environment,rules,management and spirit based on the characteristics of our center.

In view of the fact that there are no physical chemistry and structural chemistry courses in most of the non-chemistry department, the knowledge of computational chemistry of the college students is very limited. It is beneficial to quote some simulation research contents of computational chemistry properly in general chemistry teaching process. This will broaden students' vision, promote students' enthusiasm for learning, update the content of general chemistry teaching, cultivate the thinking ability, and finally improve the quality of teaching.

Herein the small-class-seminar-based (SCSB) teaching and the basic elements concerning the quality control of SCSB teaching are discussed. The exploratory practice of SCSB teaching in the Topnotch Students Scientific Development Pilot Program at Department of Chemistry, Xiamen University is introduced and several teaching cases are also presented.

During the suspending of education for prevention and control of COVID-19 epidemic, chemistry majors in colleges and universities actively responded to the requirements of the Ministry of Education that "class is suspended without stopping teaching, class suspension without learning suspension", and earnestly organized online teaching. The National Instructional Committee of Chemistry Higher Education designed three questionnaires for chemistry majors, teachers and students to make survey on the online teaching. Through analysis of the survey, some important problems and suggestions are put forward. It is of significance to promote the future online education and teaching reform of relevant courses of chemistry majors.

Inorganic chemistry is an important course for chemistry majors, which plays an important supporting role in achieving education goals and graduation requirements. In this paper, taking Xiamen University as an example, the curriculum and teaching content of inorganic chemistry were explored.

This paper elaborates how to practice the diversified teaching in "top class" of Instrumental analysis laboratory course at Xiamen University. Instrumental analysis laboratory uses the network teaching platform to achieve the communication between teachers and students in time and space, to strengthen the exploratory and innovative thinking experience through the expansibility experiments. This paper also discusses some problems in the training of top talents.

Xiamen University established the world's first undergraduate program for energy chemistry in 2015. Herein, we introduced the energy chemistry course group which includes 11 courses. We also described the curriculum system and the teaching arrangement of the undergraduates, and summarized the experience in the construction of energy chemistry major, especially the ideas of science and technology integration and collaborative innovation. We expected our teaching experience would help the other universities to apply for the energy chemistry major and set up relevant courses.

This study illustrates a comprehensive experiment covering polymer chemistry, physical chemistry and instrumental analysis. In this experiment, the temperature-responsive poly(N-isopropylacrylamide) (pNIPAM) microgels are synthesized and characterized. The PNIPAM microgels are prepared by free-radical precipitation polymerization in aqueous phase. The temperature responsive properties of PNIPAM microgels were explored from two aspects, macroscopic and microscopic. This comprehensive experiment is based on the research of cutting-edge topics, which is helpful to cultivate students' ability of integrating theory with experiment and applying knowledge to practice, as well as to train students' awareness of interdisciplinary integration.

Herein, we proposed a research-oriented computational chemistry experiment. During the experiment, students should design by-themselves the computational experiment through literature research, mechanism assumption, computational verification and data analysis. The course integration of fundamental knowledge and practical ability provided a good base to inspire the activity and creativity of the students. This experiment was set up for the realization of the target of cultivating research type talents.

In the online organic chemistry and laboratory courses, the open or semi open quizzes before class and after class are adopted to explore the "dual quizzes teaching" mode on the network teaching platform. As the progress of "dual quizzes teaching", students' learning weakness, confidence and enthusiasm are improved continuously. Through the analysis of online students' learning data, questionnaire and interactive feedback, the teachers can evaluate the learning situation of the students and regulate instructional content in time. As a result of teaching online, the "dual quizzes teaching" mode has achieved highly positive effect.
