This paper introduces the principles of marine mussels adhering solid surfaces, covering the essential contribution of DOPA to strong adhesion, the interaction modes of mucoproteins adhere to both inorganic and organic surfaces, and solidification principle of byssal, in order to serve senior high school as chemistry extending material.

To efficiently improve college students' vocational skills, five modules such as teacher skills training, pre-job training, innovation of science and technology training, multi skill training and practice effect feedback have been constructed as a new mode for vocational education. The practical effect is satisfied and worth popularized.

The significant characteristics of autonomous learning type physical chemistry textbooks were extracted out by analyzing the representative physical chemistry textbooks published domestically and overseas. The references for textbook compiling, textbook selection, teaching material selection and bilingual teaching were provided.

Combining with specific teaching cases, several implementing principles are proposed with respect to the organization art of inorganic chemistry contents. The principles involve three aspects, namely, great attentions should be paid to the combination of microcosmic and macroscopic perspectives, the combination of knowledge and method as well as the combination of thought way and scientific spirit.

Instrumental analysis is a basic course for chemistry, pharmacy and food, which plays a very important role in cultivating talents for industry and society. Based on the function of newly-established colleges, it is meaningful to reform the teaching of instrumental analysis. In our college, strengthening the cooperation with the local enterprises in drawing up new teaching content, bringing the new teaching mode of flipped classroom, and focusing on the process of evaluation methods according to the assessment for company staffs were discussed preliminarily. It is expected to open a new way in training the practical talents.

The average relative molecular weight of polyhexamethylene guanidine hydrochloride, which is a novel polymer disinfectant, is determined by the viscosimetry. Using the literature values of K = 3.8 × 10^-3 g/mol and α=1.01, the average relative molecular weight of the self-made polyhexamethylene guanidine hydrochloride is 2495, when its concentration is 0.04 g/mL. The results showed that polyhexamethylene guanidine hydrochloride with different relative molecular weight has certain antibacterial effects on escherichia coli, staphylococcus aureus, staphylococcus and pseudomonas aeruginosa at the same concentrations, and antibacterial effect is increased with the increase of relative molecular weight.

In order to improve students' innovation ability and comprehensive ability, a set of systematically integrated experiments in terms of polystyrene was provided and carried out. The internal logic relation among the systematically integrated experiments and its capacity-building advantage compared with the general experiments were analyzed. Finally, examples on the teaching methods of systematically integrated chemistry experiments were given.

Research-teaching style and corresponding exam methods were explored in organic chemistry experiment course in this study. In order to foster the students' primary research capacity, we introduce scientific frontier and researching approach to the students, guide them to do experiments and help them to finish research training, which is a kind of preparation for future undergraduate innovative training project (UITP). Furthermore, this could improve the teachers' guidance and students' research interest when doing a UITP.

In order to effectively improve the chemistry microteaching level and the quality of normal college students, a new microteaching training method based on the chemical experiment platform is proposed by analyzing the difficulties of the practical teaching and the advantages of simulation platform for chemical expericment, and as taking the example of "chlorine: the element enrichment in seawater", the methods and effects of microteaching using the platform were introduced.

Based on the theories of multiple intelligence and learning cognitive structure,the author concludes that learning is special cognitive practice, the cognitive construction of learners includes four procedures which are perception to activation,processing to understanding, connection to consolidation, and application to development.These four procedures relate and interact each other in learning process. This paper aims to state this by the cases of learning chemistry.

Physical chemistry is a very important basic course for the students in water supply and drainage major. Five teaching experiences including grasping the main thread of the course, understanding the important process of reversible process, closely combining with water supply and drainage major in teaching, trying to be understood easily and praising and motivating students appropriately are introduced in this paper.

Two cases were discussed to introduce the application of PDB database in the medicinal chemistry courses,which can greatly enrich the course content and improve the teaching quality.

In this work, a design method of calculation program for the simple system of coordination equilibrium was introduced. The quasi-Newton algorithm method was used to solve the equations for the program. The examples of iron (Ⅲ)-oxalate system were calculated with this program. The calculated results of iron (Ⅲ)-oxalate species were presented as the curves of specie distribution coefficient versus pH, initial total concentration of iron or oxalate ions. The software design is conducive to learning the basic theory and method of calculation for the complicated coordination systems in the course of college chemistry. Moreover this software also provides help in research works involving chemical equilibrium system of complexes.

On the basis of investigation and interview,this paper designed the questionnaire of comprehensive qualities of full-time master of chemical education, made an investigation on the grade 2012 full-time master of chemistry education from more than twenty normal universities, aimed at understanding the present situation of the chemical education master's comprehensive qualities, discovered the main problems, analyzed the possible causes, put forward some suggestions, looking forward to provide reference for the cultivation of master of education.

Ringbom titration curve equation of tihation of monoprotic alkali and mixed monoprotic weak acid solution and the calculation formula of pH_sp1 and pH_sp2 value in the first and the second stoichiometric point were deduced according to material balance equation MBE,proton balance equation(PBE),side reaction coefficient and conditional stability constant, etc.

In this paper, effects of temperature and time on organic synthesis reactions were discussed thoroughly based on principles of physical chemistry and organic synthesis from dynamics, thermodynamics, reaction mechanisms, solubility and so on. By reading this paper, students can understand easily how reaction temperature and time affect organic synthesis reactions so as to get the ability to analyze these effects by themselves.
