Distinguishing the diversity of electrophilic and nucleophilic reagents through multicycle of “questioning and probing” teaching mode to cultivate students’ comprehensive application of a variety of scientific thinking. Strengthening multiple teaching links such as “literature preview” “practice explanation” “comprehensive homework” and “teacher-student interaction” to deepen students’ understanding and application of knowledge, improve students’ participation in the classroom, and focus on cultivating students’ scientific thinking and humanistic quality, autonomous learning and teamwork spirit.

Taking the inorganic chemistry course reform of chemistry major of Beijing Normal University as an example, this paper discusses the optimization and reform of inorganic chemistry course from the aspects of teaching content, teaching method and curriculum assessment in order to define the teaching objectives, improve the teaching quality, meet the graduation requirements of the chemistry (normal) major, and comprehensively improve the students’ ideological and political quality, professional knowledge and skills, and educational feelings.

Chemical analysis is one of the core courses for undergraduate students majoring in chemistry and chemistry education in higher normal colleges. On the basis of more than ten years of teaching experience and the great support of the subject construction platform, teaching resources and teaching reform projects from Beijing Normal University and College of Chemistry, the teaching team of chemical analysis courses has created a new education concept of “diversified integration of teaching and research”, including the education concept, teaching mode, curriculum assessment, and ideological and political educations, etc. Practical results indicated that this chemical analysis curriculum system is greatly help for training and cultivating innovative talents in higher normal colleges in a characteristic, feasible and effective mode.

The electrochemical teaching group at Beijing Normal University (BNU) actively and systemically analyzed the limitations of the previous curriculum system and teaching modes according to the course standards and requirements for innovative talents in the new era, and performed a series of course reforms (including course content, teaching mode, examination format and curriculum ideological and political education). As expected, we have achieved excellent teaching effectiveness and realized an intension-type development of electrochemistry course, thus promoting the cultivation of innovative talents at BNU. We hope this paper is helpful to summarize graduate course reforming experiences and to find out the common problems and teaching development laws, and finally to benefit the improvement in graduate course teaching quality as well as in cultivation level of innovative talents.

After 20 years of continuous exploration of project-based learning, the chemistry education research team of Beijing Normal University has achieved fruitful results in the development of middle school chemistry curriculum resources, project-based teaching theory construction, evaluation system development, training mode development and academic research. These research and practice achievements have been promoted and applied across China, and have produced a positive and extensive influence.

Since 2003 until now, Beijing Normal University chemistry education team carried out the exploration of modeling-based teaching around “Atomic Structure and Elements Properties” theme across the middle school, compulsory module and selective module for high school. A large number of sub-topics are covered such as atomic particles and it’s spatial distribution, the extranuclear electron motion state, the configuration rule of extranuclear electron, the different element properties and so on. These teaching explorations sort out and restore the problem-solving process of scientists, and reproduce or simulate the experiments conducted by scientists. Based on the reasoning process of scientists constructing atomic structure model through experimental evidence, we design and guide students to carry out modeling activities, so that students can understand, evaluate or participate in the process of modeling, and promote the formation and development of students’ modeling ability and view of the nature of science.

Chemistry is a creative fundamental science, which is the basis of environment, life, medicine, materials and other sciences. It shows and contains novel scientific thinking methods in thinking logic. Systematically summarizing the thinking methods of chemical science can effectively solve the “complexity, difficulty and chaos” in middle school chemistry learning. In many years of teaching practice, we have put forward the multi-directional thinking method system of chemical science, focusing on the three-dimensional logical thinking discrimination of multi factors in the process of multi-level thinking. This paper focuses on the connotation of the discrimination of zero order, primary order, medium order and high-order logical thinking related to middle school chemistry teaching, and expects to emphasize the logical process of chemical thinking in chemistry teaching to realize the deep development and improvement of chemical teaching and learning in thinking mode.

“Electrolyte ionization” is an important subject of high school chemistry which is widely valued by teachers, but the teaching effect is not ideal. Students’ main performance is that they have not established a perspective of understanding matter from the microscopic view, which is directly related to the teacher’s excessive attention to the electrolyte concept in the process of teaching specific knowledge and ignoring the core literacy training function in teaching the concept of ionization. From the perspective of literacy development, “electrolyte ionization” is an important content carrier for cultivating students’ “macro-identification and microscopic analysis” literacy, and the implementation of the integration of teaching, learning and evaluation determines the teaching effect of the core concept of “electrolyte ionization”. This paper shows that through an attempt highlighting the role of water, the functional treatment of conductive experiments, the functional teaching strengthening the concept of ionization, which distinguish it from traditional teaching, the practice of integration of teaching, learning and evaluation has achieved good teaching results.

Through two typical teaching cases of element compounds, i.e. “coal pollution and prevention” and “development and utilization of metal minerals”, this paper discusses how to put the learning of element compounds in a challenging problem situation, form a basic idea of problem solving, analyze and solve practical problems from a chemical perspective, and promote the development of students’ core literacy in chemistry.

Project-based learning has a positive role in promoting students’ learning effect and future development. On the basis of practical research, this paper puts forward the principle of chemical project construction, which is to set open tasks around the core concepts of the discipline. The teaching strategy of the project implementation includes three aspects: the student-centered teaching process, the teaching process of team teaching, and the project evaluation focusing on process and reflection. Taking “synthesis and performance test of organic water retaining materials” as a project case, the whole process is described, presenting the project teaching process, and providing reference for practical teaching.

Based on the constitution of the connotation in chemistry disciplinary competence and the activity performance model, this article analyzed the college entrance examinations of chemistry of the recent three years and summarized the requirements on high-school students.

Besides, it analyzed each chemistry competency of the students in systematic practice and scoring average of each topic, thereby formed assessment in terms of grades, teachers and individual students.

Practical and innovative literacy is an important part of middle school students’ core-literacy. In this study, polymer-synthetic was taken as an example, land-competition of cotton and grain was taken as the background, and project-based learning was taken as the learning form. The results showed that students’ practical and innovative literacy was significant imoproved. At the same time, hierarchical teaching was introduced to this instruction design, which made an effective attempt to teach students according to their aptitude.

In the chemical equilibrium theory that can deal with electrolyte solution, there are relatively rigorous theoretical formula or empirical formula for the calculation or estimation of the activity and activity coefficient of ions in certain media, while the expression of empirical formula in domestic analytical chemistry textbooks is slightly arbitrary. The paper takes activity calculation of Cl^- and Al³⁺ in 0.050 mol·L^-1 in AlCl₃ aqueous solution as an example for discussion, combined with the empirical formula of activity coefficient calculation in domestic and foreign analytical chemistry textbooks. According to calculated results, the empirical formula of the activity coefficient calculation needs to be given clear application conditions.

This review summarizes the advantages, research progress and relative issues of various solid state electrolytes, including inorganic solid electrolytes, solid polymer electrolytes, gel electrolytes and composite electrolytes and the development direction of solid electrolytes are also prospected.

Non-fullerene fused-ring electron acceptors for application in organic solar cells (OSCs) have attracted great research interests because of their easy structural modulation, broad and intense optical absorption and impressive power conversion efficiency (PCE). Fused-ring electron acceptors often possess a large central planar ladder-type fused-ring donor unit, which are synthesized by complicated and low-yield ring closure reactions. The multi-step synthesis of fused ring cores will inevitably increase the synthetic cost. Recently,intramolecular noncovalent interactions by introducing heteroatoms, such as O, F, N and Se into the molecular, have been utilized to lock the adjacent aromatic units to construct the planar ladder-like core by avoiding ring-closure reactions. The noncovalent interaction can enhance the molecule planarity, expand the absorption and reduce the synthesis cost. In this perspective, we review the recent development of non-fused ring electron acceptors with the aid of noncovalent interactions and discuss the effect of this interactions on molecular structure and its photovoltaic properties and look forward to its development trend and application prospect.

Mitochondrial calcium ion unidirectional transporter is a kind of transport protein located in the inner membrane of mitochondria, which has the function of selecting and conducting calcium ions and participates in various physiological processes of cells. The components of the uniporter have been identified, including ion transporter MCU, negative regulatory subunit MCUb of MCU, two Ca²⁺ binding MICU1 and MICU2 proteins, and the regulatory subunit EMRE protein of MCU. Over the past decade, a large number of studies have proposed and constructed various models of mitochondrial Ca²⁺ uptake regulation through this uniporter. The focus of recent studies has shifted to the structure of individual components of unidirectional transporters and the structural characterization of their common complexes. These problems are solved by the continuous development of nuclear magnetic resonance, X-ray diffraction and the breakthrough of cryo-electron microscopy in structural biology. In this paper, we review the application of structural biology techniques to solve problems concerning the structure of unidirectional transporters. This paper will help us to understand the advantages and disadvantages of NMR, X-ray crystallography and cryo-electron microscopy, as well as the structure and function of each part of mitochondrial calcium ion uniporter.
