基于“以学生为中心”的教育理念,针对基于问题式学习(PBL)的有机化学教学中存在的问题,进行了基于PBL的数据驱动混合式教学改革,并以有机化学课程为例进行了实证研究。线下教学内容注重根据学生线上自主学习的时长和测验统计等学习数据找到学生最近发展区,弹性决策课堂教学内容和活动,重点解决线上学习中的难点问题,并聚焦学生课堂的深度学习与个性化教学,实现了线上和线下学习活动的有机融合。问卷调查和学习行为分析结果表明,基于PBL的数据驱动混合式教学做到以学生为中心,个性化教学,持续改进教学效果,是提升学生学习质量的一种有效的教学模式。 相似文献

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". 相似文献

Since the outbreak of novel coronavirus pneumonia (NCP) at the beginning of this year, Chinese government acted immediately and made some regulations to control the epidemic NCP and promote the recovery of society and industry including education. Chinese universities stayed on the online courses without suspension on teaching and learning. Herein, we report online teaching of structural chemistry course based on the teaching mode of online live broadcast platform, online course resources and management platforms ("1 + 2" mode). This may promote online teaching, and take advantage of online live broadcast and massive open online courses, which achieves good teaching and learning experiences on structural chemistry course. 相似文献

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. 相似文献

The spring semester of 2020 is affected by the new coronary pneumonia epidemic, which prevents the normal classroom teaching of universities in China. Nankai University actively responds to the request of "Suspended classes but not stop teaching and learning" proposed by the Ministry of Education. The online teaching software such as "Rain Classroom" and "Tencent Meeting" are used to provide online teaching to undergraduate students. This article takes organic chemistry teaching as an example and introduces the implementation process and effectiveness of online teaching. According to the particularity of online teaching, teachers must change the teaching mode to ensure the teaching work carried out effectively. 相似文献

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. 相似文献

Based on the platform of "QQ share screen + video live broadcast", through the combination of "online theory teaching", "development of home alternative experiment", "game type" experimental operation and "virtual simulation experiment", we carried out the online teaching of polymer material synthesis innovation laboratories, integrating "theory + practice" and "virtual + reality", which is also a good opportunity for labor education. These explorations and practices are expected to provide some references for online teaching of chemical laboratory courses during the COVID-19 epidemic. 相似文献

2020 spring semester has been postponed due to the novel coronavirus outbreak in the world. Taking the valence bond theory of coordination compound of "Inorganic Chemistry" as an example, we redesign and adjust the former hybrid teaching mode in view of the problems encountered in the online teaching and learning. The practice shows that the online hybrid teaching mode has cultivated the students' self-regulated learning ability, provided a good learning experience for students, and achieved good teaching effect. 相似文献

In the online organic chemistry and laboratory courses, the open or semi open quizzes before class and after class are adopted to explore the "dual quizzes teaching" mode on the network teaching platform. As the progress of "dual quizzes teaching", students' learning weakness, confidence and enthusiasm are improved continuously. Through the analysis of online students' learning data, questionnaire and interactive feedback, the teachers can evaluate the learning situation of the students and regulate instructional content in time. As a result of teaching online, the "dual quizzes teaching" mode has achieved highly positive effect. 相似文献
