《高分子复合材料》一门具有较强专业性的研究生选修课,任课教师小组尝试通过三个途径对教学方法进行改革:一是采用形象化教学,重视与研究生的互动交流,提高学习兴趣;二是充分结合任课教师小组的研究背景,通过对研究思路和研究案例的分析,提高教学的生动性;三是鼓励研究生阅读文献、整理文献并进行学术演讲,在给研究生们“喂食”的同时,培养其主动“找食”与“分享食物”的能力。近年来的教学实践表明,这些改革措施收到了良好的效果。 相似文献

Owing to the control and prevention of novel coronavirus, "online teaching" is generally suggested. The online teaching quality depends on teaching skills and students' enthusiasm. The teaching practice of structural chemistry based on teaching and research activities, electronic records, group sharing and course ideology are introduced. 相似文献

In this paper, several methods based on electronic educational resources have been presented for teaching structural chemistry. The constructions of multimedia materials, VRML models, teaching videos and website can not only improve the classroom effect, but also provide the students with a useful post-class learning platform. Meanwhile, further teaching reforms can be made on the foundations of these techniques. 相似文献

在传统的大学化学实验教学中,学生以被动接受为主,学习交互性差,自主思考不足,不利于学生综合素质的培养和创新能力的提高。随着互联网技术的飞速发展,基于各种信息化手段的教学模式应运而生。课立方系统可集预习系统、微信公众平台、翻转课堂等多种教学模式为一体,形成以学生为中心的全周期智能化教学模式,实现学生的实验课前练习测试、课堂数据记录、课后作业互评讨论等多种功能。实践表明,课立方系统应用于大学化学实验课程教学,能够有效提高化学实验课的教学效率,并且大大促进学生的自主学习,为互动式大学化学实验教学注入新的活力。 相似文献

Even though course timetabling and student scheduling problems have been studied extensively, not much has been done for the optimization of student add/drop requests after the initial registration period. Add/drop registrations are usually processed with a first come first served policy. This, however, can introduce inefficiencies and dead-locks resulting in add/drop requests that are not satisfied even though they can, in fact, be satisfied. We model the course add/drop process as a direct bartering problem in which add/drop requests appear as bids. We formulate the resulting problem as an integer linear program. We show that our problem can be solved polynomially as a minimum cost flow network problem. In our model, we also introduce a two-level weighting system that enables students to express priorities among their requests. We demonstrate improvement in the satisfaction of students over the currently used model and also the fast performance of our algorithms on various test cases based on real-life registration data of our university. 相似文献
