“化工原理”在线开放课程的建设与教学实践

Construction and Teaching Practice of the Open Online Courses of Principles of Chemical Engineering

浙江师范大学"化工原理"教学团队建设了面向化学、材料、环境与药学等非化工工艺类专业、3～4学分的"化工原理"在线开放课程,录制了101个知识点的微视频,详细讲解了流体流动、流体输送机械、传热、蒸馏与吸收等单元操作,简单介绍了非均相物系的分离、传质设备、蒸发、萃取及干燥等单元操作。课程在浙江省高等学校在线开放课程共享平台上线并运行了2年。通过多所高校、千余学生学习的教学实践,发现以学生课前在线观看知识点微视频自主学习,线下翻转课堂的混合式教学模式真正地发挥了学生学习的主体作用,教师变为课堂的组织者与引导者,大幅提高了教学的质量与效果。同时,在线开放课程可以实现优质课程的互通与共享,是高等教育改革与发展的主要方向与趋势。

The open online course of Principles of Chemical Engineering for the majors of chemistry,material,environment,pharmaceutical sciences,with 3~4 credits has been constructed by the teaching group of chemical engineering in Zhejiang Normal University.There are micro-videos of 101knowledge points,in which explain the unit operations of fluid flow,fluid transportation machinery,heat transfer as well as distillation and absorption in detail,and briefly introduce the unit operations such as the separation of heterogeneous system,mass transfer apparatus,evaporation as well as extraction and drying.The course has been online and run for two years on Zhejiang Institutions of Higher Learning Online Open Course Sharing Platform.The teaching practice of more than one thousand of students from different universities shows that the blended learning mode,which combines students'proactive learning of knowledge points through micro-videos before class with the offline flipped class,fully gives play to the students'initiative, turns the teacher into the organizer and facilitator in class,and greatly improves the teaching quality and effect.Meanwhile,the open online course enables the interconnection and sharing among the high-quality courses and is becoming the future trend for the reform and development of higher education.
