“线上线下-虚实结合”在有机化学实验教学中的应用探索——以正溴丁烷的制备实验为例

In response to the impact of the Covid-19 epidemic on organic chemistry laboratory teaching, this article analyzes and discusses the current limitation of traditional organic chemistry laboratory teaching. Taking the "preparation of n-bromobutane" as an example, a new "online-offline and virtual-actual combination" teaching mode with the combination of "Tencent Meeting, MLabs, laboratory and WeChat group" is introduced. 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.     

现代教育技术构建氧化还原反应线上实验教学的策略探索与实践

In the era of "Internet +", with the help of national excellent MOOC course of Chinese university and Mlabs-virtual experimental software, Tencent classroom is built to provide a diversified and efficient online inorganic chemistry basic laboratory classroom by combining a variety of modern education technologies with the concept of flipped classroom. Taking the redox reaction experiment as an example, we designed a multi-link teaching process and carried out a multi-faceted assessment. The online teaching can not only strengthen the cultivation of students' comprehensive and innovating ability, but also help teachers to update the teaching mode and create the new experimental content in line with the development of the times, so as to realize the mutual learning between teachers and students in the exploration of experimental teaching reform.     

通过教学过程和互动设计保障在线教学的效果

Based on the analysis of the courses and the investigation of students' online learning needs, an online teaching mode of "Tencent Classroom" and "Rain Classroom" with "split screen" is designed. This mode is used for the online teaching of "Foundation of Innovation and Entrepreneurship" and "Chemical Instrumentation and Automation". After two months of teaching practice, the teaching and learning were reflected and summarized, aiming to improve the performance of online teaching.     

基于“腾讯会议+课堂派”的有机化学课程在线教学实践

Online teaching is an important measure to carry out the "no suspension of classes" during novel coronavirus pneumonia, how to make online teaching more effective is currently the major problem. In this paper, selecting Tencent Meeting and Ketangpai as the teaching platforms, complementary with the respective advantages of the other process evaluation platforms, a new form of online teaching of organic chemistry courses was built by three approaches including reorganizing teaching resources, innovating teaching activities and reforming teaching evaluation. It provides reference for the effective implementation of online teaching.     

疫情防控期间线上教学的初步探索

This paper introduces in detail the online teaching, guiding students to participate in discussions, and the effective control of online teaching and effective combination of expertise and epidemic knowledge. The achievements were satisfied.     

有机化学实验线上课程之扬长避短教学设计与实践篇

It has been two months since a boom of online education triggered by the epidemic in China. At present, we are keeping focus on how to optimize our online class. In the case of chemistry laboratory courses, there's not much that can be done to experimental operations through online teaching. While for the traditional teaching procedure, there is still room for improvement in terms of integrating research to teaching, interactivity, etc. This paper will present some design strategies for improving teaching the organic chemistry laboratory online. To be specific, it describes how teaching materials like the lesson plan and virtual lab were coordinated into the online teaching. And we will also discuss the holistic approach to a better outcome for students' active learning and integration research into teaching by redesigning multiple phases, such as the pre-laboratory preparation, live online class, experimental operations.     

防疫期间化工原理实验部分内容在线教学的设计与实施

During the outbreak of COVID-19, the teaching team of chemical engineering principles experiment of Nanjing University uses Tencent Meeting and Pedagogy Square as online platforms, applies the unit operation experiment MOOC particularly designed by our course team, and introduces the simulation software of Oubeier Cloud Classroom and Es-online. The online classroom delivers equivalent teaching as the offline classroom.     

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".     

促进物理化学在线教学质量的实践

During the special period in the epidemic COVID-19, the five-step online teaching mode focusing on learning outcome of students has been constructed based on the national high-quality MOOC in physical chemistry and various network technologies (i.e. MOOC class, Tencent QQ group and meeting platform), which is "guide to learn boost, self-study by MOOC, online testing, timely feedback, advanced discussion". It has been demonstrated that diversified online interactive teaching strategies can effectively promote the online teaching quality, through teachers giving full play to the leading roles, encouraging and guiding students to participate in the whole online teaching process.     

以学为中心的高分子化学线上教学实践

In response to the COVID-19 epidemic prevention, the "polymer chemistry" course teaching team actively explored the "learning-centered" online teaching model. The students were guided to active learning by using the rich contents of Chaoxin online teaching platform and multiple online teaching activities. The basic knowledge points, difficulties and emphases of the teaching were highlighted and the real-time communication and Q&A were achieved in combination with the Tencent course live broadcast and QQ learning group. Following the concept of "students as the main body and teachers as the leading", the online teaching of "polymer chemistry" has effectively aroused the students' interest in learning, cultivated the initiative of autonomous learning, organically integrated the ideological and political education, and achieved a good learning outcome.
