Through a case study of the synthesis of butyl benzoate, the flipped classroom teaching mode was employed for undergraduate students in the organic chemistry experiment course. An effective way of flipping the classroom was realized via preparing the learning resources by the teachers,self-motivated learning by the students such as initiative class participation, feedback. By doing so, the learning enthusiasm of students was aroused with higher teaching efficiency. Moreover, the combination of information technology and conventional teaching promoted the advancement of teaching skills.

The training of normal students' teaching skills is an extremely important part of the teachers' professional growth. In this paper, the teaching evaluation scale of normal college students was used to observe the classroom teaching of Uygur normal chemistry students, the main problems of teaching skills of the Uighur normal chemistry students were obtained through the statistical and analysis of SPSS, and the reasons were analyzed, then corresponding countermeasures were put forward.

This paper analyzed the advantages and disadvantages of the traditional teaching mode, constructed the micro projects which integrated the teaching goal and the teaching contents through the CDIO engineering education mode, the teachers' teaching, the students' learning and doing crossed mixing, and formed a new positive and efficient teaching mode. We had tried to develop this new teaching model in the teaching of daily chemical manufacturing technology. Practice showed that the students' learning enthusiasm had been fully mobilized, and the learning effect had been improved to a certain extent in this new teaching mode. This teaching mode has a positive practical significance.

Objective & Key Results (OKRs) is one of the most advanced enterprise management modes at present. Being different from the traditional Key Performance Indicator (KPI) management mode, OKRs focuses on process, communication and self-discipline. These characteristics make OKRs management mode to be suitable for graduate research management. Under the background of expanding graduate enrollment, OKRs can effectively improve the management efficiency of graduate students, stimulate their enthusiasm for independent study and research, and then improve the quality of graduate education. Taking the Oil-water separation film as an example, we proposed a new scientific research management mode for graduate students based on OKRs, and it could provide an effective reference for graduate research management.

Up to date, the two-dimensional code technology has been very mature. Access to Internet is also very common by scanning the two-dimensional code with mobile phones. According to the characteristics of experimental teaching of chemistry in universities, the present study focuses on the way, problem, and prospect of application of two-dimensional code technology to experimental teaching and laboratory management combining with existing circumstances of chemical laboratories. The results showed that it was feasible for two-dimensional code technology to be used in experimental teaching and laboratory management. The two-dimensional code technology can not only be used to realize the synchronous teaching of classroom teaching and network teaching, but also enhance the learning effect of autonomic learning. In the meanwhile, as an auxiliary means, it can not only improve the work efficiency of the laboratory staff, but also improve the management level of instruments, equipments, and experimental materials.

1stOpt software was used in physical chemical experiment of sucrose hydrolysis reaction rate constant, the start time of reaction and the optical rotation of final reaction didn't need to determined, the rate constant of reaction can be obtained by nonlinear curve fit simply and conveniently without programming and formula transformation. This work avoided the artificial error caused by the traditional data processing method, and could supplement and improve the teaching of physical chemistry experiment.

According to the principle, analytical chemistry can be divided into chemical analysis and instrumental analysis. High sensitivity, high selectivity, high automation, digitization and intelligentization have been the development direction of analytical chemistry. Instrumental method has become the mainstream of analytical chemistry. Therefore, undergraduate students always ignore the important role of chemical analysis and its scope of application, and make the mistake that the instrumental method is universal. We chose complexometric titration method and atomic absorption spectrometry to detect lead content of test solution respectively. On the basis of the relative error of the results, we explored the scope of chemical analysis and instrumental method. It corrected the wrong ideas of the undergraduates that instrumental method is universal and it can replace the chemical analysis all the time.
