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. 相似文献

基于CeO2基氧化物制备及应用于环境保护的已有创新性成果,将其设计转化成为适合本科生的综合创新实验。在转化过程中设计了一系列的对照组,考察了沉淀pH、沉淀剂种类、过滤方式等制备条件及不同铈锆比例等因素对氧化物性能的影响。结果表明,采用环境友好的碳酸钠沉淀剂,pH控制在8–10范围内,通过简单易行的共沉淀法制得的Ce0.75Zr0.25O2氧化物,催化性能优异,污染物转化效率可达95%。本实验将前沿科技与经典实验结合,体现了科教融合和创新发展的教学理念,顺应了科技治污的号召,有益于培养学生的科学思维和创新能力,有利于提高学生环保和稀土资源战略意识,增强社会责任感和民族自豪感。 相似文献
