Resorcinarenes are the third generation of host molecules in supramolecular chemistry. This article introduced the structure and the derivatization approaches of resocrinarenes, as well as the usage of the derivatives.

Group cooperative learning, as an active learning mode, was introduced in the teaching of chemistry and chemical engineering English to stimulate the interests of students. But in the actual teaching activities, there often existed many problems such as casual grouping, low participation, ambiguous character, inefficient evaluation and other problems. Herein, by analyzing questionnaire of some classes that took part in group cooperative learning, this paper tried to supply some strategies such as reasonable grouping, appropriate guidance, suitable evaluation and so on, which could provide some theoretical evidence for the related teaching activities.

Based on the general ideas and principles of preparation experiment, we innovatively designed the "methods of guiding" and "experimental process" in writing the special topic of material preparation in Inorganic and Analytical Chemistry Experiment textbook. We expected students to be familiar with the general ideas of material preparation and to know the general principles of designing experiment scheme well via some typical preparation experiments of inorganic compounds, and focued on training the basic chemical experimental quality and the whole experiment ability of students.

This paper respectively discussed the significance of setting introduction to polymer materials curriculum, the current situation of the curriculum, the necessity of teaching reform, the effect and significance of topic teaching reform and the implementation of the topic teaching.

This paper illustrated the important status of valence bond theory in college chemistry course, analyzed the problems in the teaching of valence bond theory, and provided the following suggestions on teaching: introducing valence bond theory firstly, adding the methods of writing Lewis structure, and presenting the steps of forming covalent bond with multiple figures and perspectives.

The judgement of the R/S configuration of organic compounds is the difficult point of organic chemistry teaching in college. This article discussed the methods for designating the R/S configuration of organic compounds with different structure such as open-chain Fischer projective formula, cyclic compound and chiral molecule with no chiral carbon atom. These methods will help the primary learner with naming and identifying chiral carbon and chiral molecule.

Applying teaching methods of popularization, systematization, visualization and interestingness in inorganic chemistry could make profound theories, abstract concepts easier to understand and accept, and scattered boring knowledge easier to master.

In order to solve problems in preparing tetraammine copper(Ⅱ) sulfate such as unreasonable dosage of reagent and ammonia pollution, this paper improved the experimental device, discussed the effect of concentration of cupric sulfate solution and aqueous ammonia on the yield, determined the suitable dosage of ammonia and ethanol, analyzed the washing effect of some washing detergents, and recycled the residual ethanol in the filtrate. The optimized condition for preparing tetraammine copper(Ⅱ) sulfate was: 0.5~1.0 mol/L cupric sulfate solution reacting with 4~8 mol/L aqueous ammonia with an excess of 80%, and the dosage of ethanol is 3 times of the volume of the reaction mixture.

This paper exploited some new attempts to construct physical chemistry lab, proposed an integrative construction mode including modularizing instruments, making laboratory green and teaching innovation, and obtained excellent results in practice.

Learning style is the students' continuous learning mode, different learning styles tend to choose different learning strategies. According to the Field and Silverman learning style model,we analyzed the pre-service chemistry teachers' learning style,divided the students into different groups, and designed a variety of learning materials and teaching activities. Through teaching practice, we reflected on the impact of teaching design on students' learning efficiency.

Chemistry is an important specialized basic curriculum in secondary vocational school,it covers the essential chemistry knowledge and skills,especially for the students who major in food test or medicine etc. According to the actual situations of vocational school and students,to enhance the students' performance,oriented by working process,refered to TAFE curriculum model,we developed the novel project-based chemistry curriculum.

This paper constructed vocational activity oriented course of "fine chemical inspection technology" based on the real product inspection process, implemented in accordance with the steps of "information, decision-making, planning, implementation, inspection, evaluation", made full use of the teaching-learning-practice integrated classroom and simulation training room, made students learn by doing in different teaching environment within the limited time and space, and ultimately enabled students to learn how to learn for practice.

Compared with the traditional teaching effect, integrating teaching contents of pharmacology and medicinal chemistry could save the teaching time, improve the quality of teaching, mobilize the enthusiasm of students, broaden students' knowledge and expand the horizons of students.

According to innovative and entrepreneurial talent presently supply and demand situation of chemical engineering specialty in local college, combined with the reality of local college, this paper presented the promotion system integrating intramural classroom product design, intramural simulated practices, intramural and off-campus practices base, which had characteristics such as combining inside with outside, combining reality with simulation, stepped propulsion.

Based on the teaching practice of chemical engineering, an innovative teaching mode featured by "three modules, two steps and multiple evaluation" was established to optimize teaching practice for basic experiment, and simulate operation and production practice. By optimizing simulation and practical training, introducing simulation practice, setting up open-style simulation platform, the innovative teaching mode achieved good results.

This paper introduced the construction of network teaching system for general chemistry experiment that paid more attention to the establishment of multi-media lab, selection and processing of experiment contents and construction of network teaching platform and data processing system. Teaching practice showed that network teaching had advantages including low work intensity, high work efficiency, distinct audiovisual demonstration, fair evaluation and expanded leaning space, all of which have extremely significance in improving the teaching mode of general chemical experiment.

Through investigations and interview surveys, this paper concluded easily mispronounced chemical elements, compounds and chemistry teaching expressions among chemistry teachers and pre-service teachers in the normal nnicersities. According to the survey results, this paper put forward relevant training measures and viable memory strategies.

Ringbom titration curve equation of reversible symmetrical oxidation-reduction titration and calculation of E_sp were deduced according to material balance equation, side reaction coefficient and conditional stability constant, etc.

This article analyzed the publications in Journal of Chemical Education in 2014,described the representative study examples,and summarized the status in international higher chemical education research including the development of chemical experiments,application of educational technologies and new teaching ideas.

Irving Langmuir, winner of the 1932 Nobel Prize in Chemistry, was invited to Japan and Peking where he delivered academic lectures and had a discussion with Chinese physicists and chemists in 1934. His brilliant speech had left a deep impression on the Chinese scholars. Based on some inferences such as the Collected Works of Irving Langmuir and reports come from the press,this study was an attempt to recur the grand pictures of lectures given by Irving Langmuir in China and in Japan.
