Expertiza: Reusable Learning Objects through Active/Cooperative Learning and Peer Review

（99）正在研究如何使用基于网络的Expertiza软件，作为在各种学科课程中使用主动学习和合作学习经验的机制。 学生个人和学生团队正在选择课程主题并创建可重用的学习对象。 从讲座中获得的困难概念的示例，包括动画讲座幻灯片在内的可视化材料，以及掌握测验的问题都是正在创建的学习对象的示例。 当完成学习对象提交同行评审。 评价最高的对象正在与全班共享，并在某些情况下纳入随后的教师课堂演示。 除了开发新的主题，连续的课程正在改进和扩展以前开发的学习对象。 其结果是，高质量的教育材料正在生产与教师的时间需求较少。 研究表明，妇女和代表性不足的少数群体对主动学习和合作学习技巧反应良好。 Expertiza的使用也显示出类似的结果，提高了这些群体的保留率，提高了课堂表现。

Interdisciplinary (99)Research on the use of web-based Expertiza software as a mechanism for using active learning and cooperative learning experiences in courses offered in a variety of disciplines is being conducted. Individual students and student teams are selecting a course topic and creating reusable learning objects. Worked-out examples of difficult concepts from a lecture, visualization materials including animated lecture slides, and questions for mastery quizzes are examples of the learning objects being created. When completed the learning objects are submitted for peer review. The most highly rated objects are being shared with the entire class and in some instances incorporated into subsequent faculty classroom presentations. In addition to undertaking development of new topics, successive classes are improving and extending previously developed learning objects. The result is that high-quality educational materials are being produced with less demand on faculty time. Studies have shown that women and underrepresented minorities respond well to active learning and cooperative learning techniques. The use of Expertiza is showing similar results with improved retention of these groups and increased classroom performance.
