Due to its widespread existence, hydrogen bond is highly valued in the field of chemistry. “Lithium bond” has some features similar to hydrogen bond, but the metallicity and relatively large atomic radius of lithium make “lithium bond” has its own unique characteristics. On the basis of hydrogen bond, this paper introduces the concept, structural characteristics of “lithium bond” and its application in lithium batteries, which is helpful for people to deeply understand and apply “lithium bond”. Considering that the new concept of “lithium bond” is rarely mentioned in chemistry teaching currently, it is expected that the knowledge related to lithium bond chemistry will be appropriately involved in the future. This means keeping up with the trend of scientific and technological development, thereby further cultivating students’ awareness of scientific research and innovation.

On the basis of clarifying and comparing the achievements of the Nobel Prize in Chemistry in the field of organic synthesis since the 21st century, this paper states the present research situation of organic synthesis in China, and puts forward some suggestions for the future direction of organic synthesis in China.

For meeting the needs of the reform of the large-category enrollment and training mode, it is proposed that the general education construction for the senior chemistry professional courses that can proclaim the main character and charm of the major should be performed for the lower-grade undergraduate students based on the in class and out of class training scheme, which is denoted as “one combination, two connections and three types of reforms”. These reforms aim to improve the training program of large-category education, so that students can rationally choose their specialized subject before the major diversion and then make adequate preparation for their future career.

In view of the current situation of chemistry course learning in colleges and universities, this paper discussed the problems about course difficulty, students’ foundation and learning purpose, and put forward the necessity of teaching reform. Reform research and practice was carried out about “student-centered” teaching method, teaching tools and teaching ideology. The single teaching method was changed, and the “hierarchical” teaching and guidance was used, thus the differences of chemical fundamentals between students were narrowed, and the difficulty of learning was reduced. Various teaching tools were used for online-offline hybrid teaching, such as MOOC and other platforms, some course contents were taught and practiced in detail and repeated online, and some basic knowledge was consolidated, some key points were emphasized offline, the students’ online learning was supervised and managed through the background data and online test, and that was connected with the offline homework and exams, so it was assured that online and offline essence equivalent. The teaching ideology was reformed, some examples were used to introduce how to integrated the political elements into the chemistry course, so as to stimulate students’ enthusiasm for learning, help them to establish a good view of life and world outlook, and then make teachers really do “both teaching and educating”.

Based on the concept of new engineering, our university addresses the painful problems that exist in the traditional separation engineering courses, such as “the comprehensive quality and ability of the teaching staff are not highly compatible with the requirements of the construction of new engineering”, “the teaching mode emphasizes knowledge but not the cultivation of students’ ability and value”, “the overall design of the course is not cutting-edge and contemporary”. The course reform and practice are carried out by building a high-level faculty, integrating the thinking and politics of the course, writing internationally certified teaching materials, innovating teaching methods, carrying out all-English teaching, and improving diversified evaluation mechanisms. This has broadened students’ international perspective, strengthened their higher-order thinking, diversified and comprehensive engineering ability, and engineering literacy.

Based on the characteristics of elemental chemistry curriculum, the teaching team designed and constructed the curriculum ideological and political case database integrating “science”, “humanities” and “ideology and politics”, and integrated it into each stage and link of online and offline mixed progressive teaching practice to synchronously realize the trinity teaching goal of knowledge imparting, the ability training, the value shaping. At the same time, the collective teaching and research system was established to ensure the integrity and continuity of course ideology and politics.

According to the teaching objectives, student-centered conceptand output oriention, the teaching contents and methods of “surface tension”are carefully designed, and the ideological and political elements of each teaching link are fully explored in order to integrate value shaping, knowledge imparting and ability cultivation. The results of comprehensive homework and questionnaire survey show that themultiple teaching patterncan better integrate teaching content with ideological and political elements and realize the unity of knowledge and action, which is conducive to the cultivation of students’ comprehensive quality.

Based on the characteristics of structural chemistry and computational chemistry courses and the analysis of students’ learning, we propose a teaching strategy by organically combining structural chemistry with computational chemistry during the teaching. It provides a good learning method for students to understand the abstract concepts and theories of structural chemistry and understanding the basic knowledge of computational chemistry, as well as a good teaching strategy for teachers.

Through an in-depth introduction to the concepts of esterification reaction, transesterification reaction and aggregation-induced emission, as well as a comparative analysis of different synthesis methods of hyperbranched polycarbonate, students are guided to understand the cultural ideas that “tradition breeds innovation”. Using diethyl carbonate and glycerol as raw materials, a simple transesterification polycondensation reaction was used to design and synthesize hyperbranched polycarbonate with aggregation-induced emission effect. The ultraviolet absorption and fluorescence properties of hyperbranched polycarbonate were studied by UV-Vis spectrophotometer and fluorescence spectrometer. Finally, the aggregation morphology and size of hyperbranched polycarbonate were studied by scanning electron microscope and laser particle size analyzer to explore the luminescence mechanism. The whole experiment teaching starts from perspective of science, and allows students to understand the cultural connotation of “tradition breeds innovation” from the teaching theory of synthesis principle and luminescence mechanism, which not only cultivates students’ enthusiasm and interest in scientific research, but also allows students to master the operation of advanced equipment operating skills, cultivate students’ comprehensive experimental ability and humanistic qualities.

The scientific research of new fluorescent probes that used for Cu²⁺ ion analysis was transformed into the expansion experimental teaching of analytical chemistry, which covering structural analysis, qualitative analysis and quantitative analysis. Students can intuitively understand the coordination reaction between fluorescent probes and Cu²⁺ through the fluorescence “on-off-on” experiment, design and establish new analysis method, explore the complex ratio of fluorescent probe and Cu²⁺, and finally apply the fluorescent probe technology to actual sample analysis and rapid analysis to encourage them to put what they have learned into practice.

In order to introduce the frontier achievements into the comprehensive experiment of undergraduates, a new comprehensive chemical experiment for green extraction of elemental gold from electronic waste using NBS-Py system was designed. By the guidance of redox and coordination theory, the gentle, high-efficiency, and low-toxicity of N-bromosuccinimide-Pyridine (NBS-Py) system is used to effectively extract gold environmentally in electronic waste. Since this gold-extraction method contains important knowledge principles, basic experimental skills and some characterization techniques, it is transformed into a comprehensive teaching experiment. During the processes of leaching, extraction, reduction, calcination and structural characterization, we always carry out the problem-oriented inquiring teaching mode. The application of innovative experiment in teaching process can improve students’ basic experimental skills and promote students to utilize basic theoretical explaining experimental principles. Through designing experiment scheme independently and implementing experiment processes cooperatively, every link in the whole experiment teaching process is helpful to improve students’ scientific research ability and innovation ability.

The lesson plan of nature of science (NOS) is the basis of NOS teaching practice. This study evaluated NOS lesson plan of 35 pre-service science teachers. Data sources include NOS lesson plans, semi-structured interviews, informal interviews, and other multiple data. Data analysis applied the “explicit-reflective” teaching as the framework, and coded NOS lesson plan from six aspects: setting instructional objectives of NOS, integrating traditional teaching content with NOS, creating situations related to NOS, asking questions about NOS, discoursing questions about NOS, and reflecting on NOS. The results showed that preservice science teachers can take the NOS as a cognitive goal, excavate the content of the NOS in curriculum materials, and create well teaching situations of the NOS, but they do not perform well in the problems, discussions, and reflections of the implementation of NOS lesson plan. This indicated that preservice science teachers still have difficulties in transforming “explicit-reflective” teaching into concrete and practical lesson plan.

In the problem-oriented organization structure of carboxylic acid knowledge module, design “six-step” teaching mode, namely “guide, learning, analysis, thinking, exploration, expansion”. Thinking prompt, problem-oriented, discussion and interaction are the main line of teaching activities. Combining with the creation of professional and life teaching situations, problems are explored and solved from simple to profound, so as to achieve the goal of internalizing the subject knowledge and developing the core accomplishment of chemistry.

According to the result of questionnaire survey, this paper analyses the material class specialized elective course existing problems and causes. And then we propose the direction of teaching reform, including the clear purpose of the students’ course selection, dynamic adjustment of teaching contents, multiple teaching mode and multi-angle assessment method.

In this paper, taking L-tyrosine as an example, a teaching scheme combined with computational chemistry methods for collecting UV-Vis absorption spectra was designed, and the specific application of computational chemistry in the teaching of UV-Vis spectroscopy was also discussed. By simulating and identifying its UV-Vis spectrum, as well as analyzing its different electronic excitation processes, it is not only able to effectively explain the origin of absorption peak in the experimental spectrum, but also obtain a series of isosurface graphs and data with educational significance. These investigations shall be helpful for students to strengthen the perceptual understanding on the type of orbital transition, electron transfer, hole-electron distribution, and other excitation characteristics, so as to improve the interest, vividness, and theoretical depth of teaching content.

Electrochemical thermodynamics establishes the relationship between the reversible battery electric potential and the corresponding battery reaction thermodynamic function. Electrochemical oxidation of 5-hydroxymethyl furfural (5-HMF) to produce 2,5-furandicarboxylic acid (FDCA) can replace the traditional polyethylene terephthalate (PET) route for preparation of bio-derived plastics, but no accurate experimental data are available for the standard electric potential of the reaction and the standard reversible electrode potential of each step. In this paper, these data are calculated by the literature thermodynamic data. The results confirmed that the oxidation reaction of HMF occurs first than the oxidation reaction of water in terms of both thermodynamics and electrochemistry, and the electrochemical oxidation of HMF is easier to proceed in a strong alkaline solution. The obtained data can be added to the electrochemical tool books as reference. The work is introduced as a comprehensive exercise into the teaching of electrochemical thermodynamics. It helps to deepen the understanding on the relationship among various parts of physical chemistry, improves students’ ability to apply physical and chemical knowledge to solve practical problems.

Polyhalogenantion of ketones and the Favorskii rearrangement of α-haloalkyl ketones are important reactions in the teaching chapter of aldehydes and ketones and both of them occur under basic conditions after enolization. However, the former enolizes in the halogenated α-carbon atom, the later does in the non-halogenated α-carbon atom. These enolizations “at random” usually make students confusing. They are thought to be contradictory by students. This article rationally explains the rationality of the enolization in the Favorskii rearrangement and resolves the “contradiction” in teaching through analyses of the reversibility in the enolization of α-haloalkyl ketones and the irreversibility of the Favorskii rearrangement.

According to the Journal of Chemical Education on the theme of “coordination chemistry” in the past ten years, we analyzed the publication of the theme from four different perspectives, including literature column distribution, keyword analysis, and teaching case types. Then representative teaching cases were introduced based on the four dimensions, including fun activities, production and life, model teaching and information technology. Finally, the research suggestions for promoting the effective teaching on the theme of “coordination chemistry” are proposed, which provide guidance and reference for the teaching research on the theme of “coordination chemistry” and the teaching experience for the teachers in China.

Archives information management is of great significance to ensure the normal operation of the dynamic complex system of collaborative education training platform integrating industry, scientific research and teaching and the effective implementation of practical teaching. Taking the material discipline training platform of Qingdao University as an example, the problems existing in the process of realizing the archives information management of the dynamic complex system of the practical training platform and the corresponding countermeasures were studied. The results show that there are some problems, such as the complexity of the component elements of the archives information, the diversity and timeliness of the collection and arrangement of the archives, and the strong dependence on the archives information management mechanism in implementing the archives information management of the training platform. The countermeasures to realize the archives information management of dynamic complex system include accurately sorting out the relationship between various archives elements, designing a reasonable archives information management system and scientifically constructing the archives information management mechanism serving practical teaching.

As an early exploration of the science society of Peking University, the Chemistry Department of Peking University first established the “chemistry lecture club” in 1917, and then launched the “true society”. Although some extracurricular activities were carried out, those societies were small in scale and short in duration. In 1922, the Chemical Society of Government University of Peking with more standardized organization was established, which finally became an important platform for gathering students to carry out extracurricular learning and provided powerful assistance for classroom education. The development and evolution of student associations in the Chemical Society of Government University of Peking reflects the rising willingness of students’ autonomy and collective research in this period. The participation and activities of associations are beneficial to the growth of students. However, due to the lack of scientific culture ,the constraints of social environment and political situation, scientific associations at that time still faced many obstacles in the process of development.
