Enhancing Student Learning in Introductory Physics through the use of Multimedia Learning Modules

物理（13）本项目解决了物理导论教学中存在的一个长期存在的问题：学习物理导论的学生不愿意在上课前阅读课本，也没有准备好参加旨在完善概念理解和提高解决问题能力的课堂活动。该项目的多媒体学习模块（MLM）用于两学期基于微积分的物理入门课程，通过将动画视频与附带音频相结合，结合多媒体学习研究的既定学习原则，以吸引学生的听觉和视觉工作记忆，从而提高他们对材料的掌握程度。传销教授基本的概念知识，并与即时教学（jit）一起使用，以改善学生的课前准备，从而腾出课堂时间用于其他用途。一项试点研究表明，使用传销的结果显著更多的学生学习比使用传统教科书紧随其后的教训，学生保留显著更多的学习材料，通过传销两周后提出。与教科书相比，支持传销的收益相当可观，在统计上也很显著。传销对学习的影响是通过制定一套问题来评估的，这些问题是在传销实施前后的每次讲座之前管理给学生的，并通过比较实施传销前后的安全期末考试的表现来评估的。这些材料也在与伊利诺伊大学厄巴纳-香槟分校的学生人口结构截然不同的合作院校进行了测试。

Physics (13)This project addresses a documented and persistent problem in introductory physics instruction: Students taking introductory physics are loath to read the textbook prior to coming to class and are unprepared to participate in classroom activities aimed at refining conceptual understanding and promoting problem solving skills. The project's Multimedia Learning Modules (MLM) for the two-semester calculus-based introductory physics course incorporate established learning principles from research on multimedia learning by combining animated video with accompanying audio to engage students' auditory and visual working memories which improves their mastery of the material. The MLM teach basic conceptual knowledge and are used with Just in Time Teaching (JiTT) to improve students' pre-class preparation, thus freeing up class time for other uses. A pilot study demonstrated that the use of the MLM results in significantly more student learning than the use of traditional textbooks immediately following the lessons and that students retain significantly more of the learned material presented via the MLM two weeks later. The gains favoring the MLM over the textbook were sizable and statistically significant. The impact of the MLM on learning are evaluated by developing a set of questions that are administered to students prior to coming to each lecture both before and after the MLM are implemented, and by comparing performance on secure final exams both before and after implementation of the MLM. The materials are also being tested at partner institutions that have a very dissimilar student demographic profile from the students at the University of Illinois at Urbana-Champaign.
