Due to emphasizing the abstractness and logic, Physical Chemistry is deemed as one of the most difficult subject for both chemistry and non-chemistry majors, which involved strong background of higher mathematics. Here, we try to discuss the teaching and learning issues related to this subject, and explore the solution to improving the teaching-learning efficiency.

: A new teaching model, micro-teaching, is proposed in era of information, and the new teaching design philosophy focusing on the features and the present situation of inorganic chemistry laboratory teaching, micro class platform was built by using WeChat public account to assist the classroom teaching. It solved the problem of the inorganic chemistry laboratory teaching, such as the safety training, students’ preview, more contents but less lecture time, limited resource of experimental reagents, lack of the protection from toxic reagents. Through micro-teaching, experimental content diversification and demonstration operation visualization were realized. It improves students’ subjective initiative in learning, strengthens their hands-on ability, standardizes the experimental procedures, facilitates students to grasp the key and difficult points of the experiment, strengthens the communication between teachers and students, meets the requirements of students at all levels, and improves the efficiency of the classroom teaching.

: The cyclohexanone preparation is an important experiment in fundamental organic chemistry laboratory for college students. In this paper, NaClO-TEMPO-TBAB catalytic oxidation reaction was used to replace chromic acid oxidation reaction, avoiding concentrated sulfuric acid and chromium-containing waste. At the same time, the reaction conditions were optimized to achieve small scale and shorten operating time which can train and improve students’ operation skills in the experiment.

The 2019 Nobel Prize in Chemistry was rewarded to three scientists, John B. Goodenough, M. Stanley Whittingham and Akira Yoshino, for their great contribution in the field of lithium-ion batteries. After more than 40 years’ development, lithium-ion batteries have been widely used in our daily life, which is inseparable from the creation, exploration and hard work of millions of scientists all over the world. This paper expatiates the scientific spirit of innovation, pragmatism, interdiscipline and cooperation, and demonstrates the importance for scientific research as well as talents cultivation from the views of the stories of the Nobel laureates especially of Professor Goodenough.

R. China. Abstract: Based on the characteristics of general chemistry course, we explore the joint point between the professional knowledge and ideological and political elements in the teaching process, and outline the implementation of ideological and political education in terms of allowing the students to develop the historical materialism, patriotism, sense of social responsibility and green development idea. By using the classroom teaching as the major approach, we push forward the important all-round education practice involving all staff in the whole-process, so as to assure implementation of the fundamental task of strengthening moral education and cultivating people in a systematized way.

Abstract: The crop science of Sichuan Agricultural University is an authorized first-class discipline. As the strategic supporting department for innovative talent cultivation in agriculture and forestry major, we are facing a long-term challenge in reforming the teaching mode for basic course-organic chemistry and cultivating talented students with solid basic knowledge and strong sense of innovation. Herein a thorough survey was performing to establish the executable teaching programs for this course during the “Double-First Class Universities Plan” period. A multidimensional teaching resource library for organic chemistry course was also constructed. The new classroom teaching mode “Interest cultivation-Creative thought developmentAutonomous and Cooperative learning”, along with a stepwise practice teaching mode “Foundation skills-Integrated application-Innovative trial” was proposed and practiced among thirty-five majors including agriculture, forestry and veterinary, to improve the quality for innovative talent cultivation and support our first-class discipline construction. This research could probably serve as a reference for congeneric agricultural university.

: This paper expounds the importance of logical thinking in the teaching of analytical chemistry and shows the internal logical relationship of the knowledge of analytical chemistry. Based on the logical relationship, the teaching design of the main content of analytical chemistry is carried out. In teaching practice, twice as much can be accomplished with half the effort with deep thinking and effective use of the progressive logical relationship inside and between chapters, and focusing on combing the main line of knowledge points. Then, the teaching difficulty can be effectively reduced and the students' learning interest and the teaching effect can be improved. At the same time, the rigorous logical thinking ability and scientific research innovation consciousness of the students can be trained.
