在线大一数学课程的保留率低是一个令人关切的问题，特别是在为学术准备不足的学生服务的中学后机构。本研究的目的是，以确定学生的表现在很大程度上依赖于基于文本的多媒体工具的在线大学代数课程，可以通过更换教师生成的教育资源与教师生成的视频讲座得到改善。最初的在线大学代数课程将教师生成的教育资源置于内容提供者的角色，在在线家庭作业系统中启用所有教师生成的学习辅助工具，并将教师生成的教育材料视为补充资源。相比之下，重新设计的在线大学代数课程通过要求学生在观看教师生成的视频讲座的同时完成教师生成的指导笔记表，将出版商生成的学习辅助工具视为补充资源，从而增强了课程教师的教学效果。从在线家庭作业系统中删除。结果表明，学生谁参加了重新设计的在线大学代数课程，战略性地将教师的角色的内容提供者进行了显着更好的在线和手写的评估比学生谁参加了在线大学代数课程，把教师生成的教育资源在该角色。
Low retention rates in online freshman-level mathematics courses are a concern, especially at postsecondary institutions that serve academically unprepared students. The purpose of this study was to determine if student performance in an online College Algebra course that relies heavily on text-based multimedia tools can be improved by replacing publisher-generated educational resources with instructor-generated video lectures. The original online College Algebra course placed the publisher-generated educational resources in the role of content provider by enabling all publisher-generated learning aids within the online homework system and treating instructor-generated educational materials as supplemental resources. In contrast, the redesigned online College Algebra course enhanced the course instructor’s teaching presence by requiring students to complete instructor-generated guided note-taking sheets while watching instructor-generated video lectures, treating publisher-generated learning aids as supplemental resources by removing them from within the online homework system. Results indicate students who enrolled in a redesigned online College Algebra course that strategically placed the instructor in the role of content provider performed significantly better on both online and handwritten assessments than did students who enrolled in an online College Algebra course that placed the publisher-generated educational resources in that role.
