This paper proposed a novel qualification mechanism for operating large-scale instruments independently. According to the mechanism, applicants could train autonomously via virtual laboratory system on the instrument reservation platform of analysis and testing center, and they would gain the qualification for operating independently after passing unsupervised appraisal and practical test. The virtual laboratory system was very flexible, highly individualized and especially suitable for independently training of applicants with different professional background and operational abilities. This mechanism could promote efficiently scientific optimization management of large-scale instruments sharing platform, improve the efficiency of large equipments, and provide a new thinking of experiment teaching reform.

This paper introduced the teaching reform of polymer materials research methods from theory teaching, practice teaching and evaluation system in order to cultivate applied talents with innovative spirit and practical ability. This paper emphasized that theory teaching and practice teaching should be highly integrated, which could lead to good teaching effect.

This paper discussed the calculation of thermodynamics functions of chemical reaction such as molar enthalpy, molar internal energy, molar Gibbs function and molar entropy from the derivation of the equations, the model of hypothesis, approximate treatment method and the relationship between these functions.

In view of the incorrect setting of teaching contents, nanny teaching mode and single teaching method in the teaching of analytical chemistry experiment, this paper proposed a novel experiment teaching system and reformed experiment teaching methods through changing the teaching concept. The proposed system and methods could promote students' interests in experiments, cultivate their responsibility and spirit of exploration, and enhance the manipulative and innovative ability of students.

On the basis of teaching and research platform of national experimental teaching demonstration center for training innovative talents, this paper constructed a new experimental teaching mode of learning, research and innovation for chemistry and chemical engineering major, and focused on cultivating students' ability of application, innovation and entrepreneurship .

This paper described the importance of detail teaching for organic chemistry experiment taking the synthesis of acetanilide as an example. First, the students were divided into two groups and different methods were used to carry out the teaching. Then the students' experimental results were compared and analyzed. The results showed that the details of teaching were directly related to the correct operation of experiments. The problems in students' synthesis of acetyl aniline were summarized and analyzed, and the key points of the experiments were put forward.

The teaching means including multimedia educational technology, videos, microteaching and applied software were applied in undergraduate chemistry experiments, which not only visualized the abstract chemical revealed complicated experimental principles but also could make the class more interesting, motivate students' learning interests, improve innovative consciousness, and enhance the efficiency of experiments.

In 2015, Northeast normal university revised teacher education curriculum and constructed a chemical education curriculum system that changed educational practice from campus simulation to off-campus, which improved the teaching practice ability of normal school students gradually, and laid a foundation for being a good chemistry teacher in the future. But in the integration of theory and practice, the instructor team-building and security measures need to be further considered.

Emotional participation and situation setting can lead secondary vocational students major in pharmacy to initiatively study chemistry. This paper introduced situation setting method such as designing questions, doing experiments, presenting pharmacy history and science stories, and sharing daily life experiences and social focus.

This paper studied the water in Terrymitt sodium by Karl Fischer's, loss on drying, thermal gravimetric analysis, single crystal X-ray diffraction, elemental analysis, dynamic vapor sorption analysis and other methods, which could guide students to strengthen the understandings of water in drugs and get research ideas.

Based on three-dimensional teaching objectives and the characteristics of Chinese traditional medicine chemistry, this paper expounded the application of three-dimensional teaching design in Chinese traditional medicine chemistry from course characteristics, the analysis of students, three-dimensional teaching objectives, the difficulties and key points, instructional strategies, teaching methods, teaching process and teaching evaluation and reflection.

In view of the problems existing in the chemistry teaching for related fire protection major, this paper put forward some chemistry teaching strategies. These strategies included choosing teaching contents according to the requirements of fire protection; using case teaching mode; introducing the knowledge of chemical process, assessing and controlling methods of chemical hazards through the properties of typical compounds and their preparation methods; teaching of analytical chemistry through investigation on typical fire accidents; infiltrating ideas of green chemistry and green fire protection; and introducing new advances of chemistry to classroom teaching.

In view of the current problems in the teaching of inorganic chemistry experiment, this paper proposed and implemented the diversified experiment evaluation mode. The teaching practice showed that the improvement of experiment examination and evaluation methods with fair and accurate assessment of students' experiment performances could stimulate students' interests and improve students' experimental ability and the ability to analyze and solve problems.

This paper mainly introduced the application of physical chemistry in the design of pharmaceutical dosage form to optimize the pharmacokinetic parameters, the proper selection of pharmaceutical excipients and pharmaceutical dried technology to show the important guide of the basic theories of physical chemistry in pharmaceutics. The aim of this study was to motivate the learning interests of students major in pharmaceutics and promote teaching quality of physical chemistry by integrating the physical chemistry teaching with the pharmaceutical specialty knowledge.

This paper summarized and discussed issues in the practice and exploration on full-English teaching of postgraduates' professional courses "Principles of Catalysis II". Student-centered teaching mode was developed in terms of construction of course contents, building of teaching team and the improvement of teaching methods. On the basis of our own experiences and reflections, a "virtual parallel class" idea was proposed to improve the effectiveness of the full-English teaching.

This paper predicted the electrophilic substitution reactive site of heterocyclic compounds by condensed Fukui function. Results showed effective prediction for penta-cyclic compound, while poor prediction for hexa-cyclic compound. Then the frontier molecular orbital theory was employed for reactive site prediction, and the results indicated that p_z orbital character of the highest occupied molecular orbital was an effective criterion.

Flash calculation is the foundation of distillation operation. Five different cases of feeding status for multi-component flash operation were described and solved with Excel in detail. The fast and brief method elevates efficiency greatly for flash-problems.
