UOOC平台与腾讯课堂相结合的“在线异步教学”

The COVID-19 broke out on a large scale, and online teaching became the first choice for teachers. Avoiding network congestion and ensuring learning effects are the dilemmas faced by online teaching. With the help of the UOOC platform and the Tencent Classroom, taking the "Polymer Structure and Performance" course as a sample, we suggested a new "online asynchronous teaching" model. Among them, the SPOC course is convenient for students to manage their learning time; "Chapter Quiz" and "Student-to-Student Mutual Evaluation" are helpful for students to obtain multi-angle feedback; project tasks are focused on case analysis so that students carry out inquiry-based learning. Overall, the "online asynchronous teaching" model breaks the time and space restrictions on teaching and learning, guarantees the quality of teaching during the epidemic, and lays the foundation for creating a "golden class".

The practice of the new mode of teaching includes the following steps: pre-class online guiding by teacher, student preview and practice based on the virtual simulation platform, students and teacher discussion and operation in laboratory, and post-classcomprehensive assessment and Q&A", and good teaching effects have been received. It is significant in cultivating and improving the independent innovation and practical ability, and provides reference for the organic chemistry laboratory teaching reform and also lays a foundation for the construction of "outstanding course" of organic chemistry.     

有机合成化学"三位一体"混合教学模式探索与实践

In order to improve the quality of teaching and cultivate chemical innovation talents in university for nationalities, in the course of organic synthetic chemistry curriculum construction, efforts were made to overcome problems such as the single teaching objective, abstract and boring teaching content, tedious and relatively dull teaching methods and low enthusiasm for students' learning, etc. According to the study rule of "before class-on class-after class", the trinity mixed teaching mode of "teaching goal-teaching means-practice examination" was constructed. Through the construction of the "teaching goal-teaching means-innovative practice" trinity mixed teaching mode, we refined teaching objectives, optimized teaching methods, implemented small classes, improved assessment methods, designed comprehensive laboratory programs, reinforced practices, and reformed the assessment measures. Discussion on teaching reform and practice of organic synthetic chemistry was carried out from multiple perspectives. Through the practice of teaching reform, the teaching effect has been improved, the enthusiasm of students to learn organic synthetic chemistry has been improved, and the expected effect of cultivating students' innovative ability has been achieved.
