计算机在化学教学中的优势

1“教师为主体”的旧的教学模式被瓦解代之而起的是“学生为主体”的新的教学模式在教学过程中,我们一直强调学生是学习的主体。但传统的教学方法很难发挥学生的主观能动性。教学活动仍是以教育者为中心,以语言传播为主要手段的活动。教师是知识的传播者和专家,学生是学习者和听从者。一张嘴、一支笔、一本教材、一叠讲稿的局面在很大程度上限制了学生主体作用的发挥。而教师的主导作用是由教师各方面的因素决定的,如教师的知识掌握程度、语言表达能力、组织教学的能力、对学生的认识和态度、师生关系的处理、教师的精力和工作情绪等。…

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.     

关于应对疫情开展化学类专业课程线上教学的探究

This paper aims at the implementation of the online courses of chemistry majors in Sichuan University in response to the epidemic, and explores a more effective and reasonable way to organize teaching. Based on the investigation and feedback of teachers and students, this paper points out the difficulties and challenges of online teaching at the present stage:the classroom interaction and discussion are not smooth, the online teaching tools and methods are diversified, and the chemistry laboratory courses are not matched. Therefore, the School of Chemistry of Sichuan University will coordinate the online teaching platform, enhance the classroom interaction, and launch the "chemistry virtual simulation experiment teaching center" to ensure the teaching progress and quality during the epidemic prevention and control.
