基于信息化课堂教学活动的定量有效性分析

Quantitative Validity Analysis on Information-based Classroom Teaching

信息化教学历经从黑板到白板、从一对多、面对面教学到一对一、电教录像推广,再到交互式网络空间学习;从有限局域网到移动互联网无限制学习;从物理空间到数字空间无限制学习。虽然针对信息化教学设计案例的探究层出不穷,但大多偏重定性描述和教学过程师生活动安排的合理性讨论,对教师、学生和媒体之间信息流动关系的定量研究较少,不能及时运用课堂活动反馈的数据对教学活动行为进行有效性分析。本文以《钢筋混凝土结构功能函数表达》为载体,以课堂移动客户端(蓝墨云)教学活动数据为支撑,对课堂教学活动有效性进行分析,探索课堂教学数据对教学活动效果评价的有效性,为其他项目同类课程效果评价提供借鉴。

Information-based teaching has experiences many changes： from blackboard to whiteboard,from face-to-face teaching to teaching of audio-visual video and then to interactive network learning, from limited local area network to infinite internet, from physical space to cyberspace, and so on. Although there areconsiderable researches on information-based teaching, they mainly focus on analyzing the rationality of teach-er-student activities while hardly on quantitative validity. Taking the course of the Function Expression of Rein-forced Concrete Structure as an example, supported by the data of the teaching activities from the mobile clientLanmoyuan, this paper analyzes and explores he validity of classroom teaching. This paper is expected to serveas a reference for the validity evaluation of the same kind of courses.
