“大学物理”在线课程资源现状与启示——以“爱课程”平台为例

The Status Quo and Enlightenment of Online Course Resources of “College Physics”——Taking the Platform of “I-Course” as an Example

以"爱课程"平台上与"大学物理"相关的45门在线课程资源为样本,从在线课程资源建设和应用两方面展开统计和分析后发现:课程的建设学校大多集中在华东、华中和华北等区域,课程的拍摄以课堂实录式和绿幕抠屏式两类为主,在线开放课程以知识点的讲解为主,呈现直线逻辑的内容组织方式,资源共享课则涵盖理论和实验两方面,呈现螺旋逻辑的内容组织方式,视频公开课以课外拓展为主,属于逻辑式内容组织;在线开放课程视频的平均时长约为11分钟,资源共享课和视频公开课的视频平均时长均在30分钟以上,且在线开放课程可应用的方式最多。建设者可选择演播式和绿幕抠屏式视频拍摄方式,从而保证视频质量。应根据学习者的认知水平层级建设课程内容,开发与课堂无缝接轨的在线课程资源,从而提高资源的利用率和培养学生的高阶认知能力。

Taking the 45 online course resources related to "college physics" on the platform of "i-course" as samples,statistics and analysis were carried out from the perspectives of the construction and application of online course resources.The results show that schools ofcurriculum construction are mostly centralizedin east China,central China and north China.The coursesare mainly shot by two modes: classroom record and green screenvideo shooting.Online open courses and resource sharing coursesare both textbook-orientated.The former focuses on the explanation of knowledge points,presenting the organization content mode of linear logic.The latter covers both theoretical and experimental aspects,presenting the organization content mode of spiral logic.Video open courses are learning-activity-orientated with extracurricular expansion as the main task,and belong to the organization content mode of logic.The average video duration of online open courses is about 11 minutes,while the average video duration of bothresource sharing courses and video open courses is over 30 minutes.Online open courses can be applied in the most ways.Curriculum constructers can choose the modes of broadcast and green video shooting so as to ensure video quality.They should construct the curriculum content according to the hierarchy of learners' cognitive level and develop the online course resources that are seamlessly integrated with the classroom,so as to improve the utilization rate of resources and cultivate students' high-order cognitive ability.
