Conceptests and Screencasts for Core Chemical Engineering Courses

工程-化学(53)通过这个项目，正在开发概念测试和屏幕演示，以支持化学工程的六门基础课程：材料和能量平衡、流体、传热学、传质和分离、化学工程热力学和化学反应工程。概念测试是多项选择题，在课堂上使用学生操作的点击器，通过与同龄人的讨论和教师反馈进行互动学习。与概念清单上的问题类似，概念测试通常涵盖学生经常误解的基本主题。除了用作课堂练习外，概念测试还可以用于在线测验，涵盖学生在课前完成的指定阅读，或者用于课程的家庭作业或考试。屏幕截图是由教师讲述的材料的简短屏幕截图，例如数学问题的解决方案、迷你讲座、使用新软件的培训或解决概念测试的策略讨论。截屏视频可在网上获得，并在学生需要时为他们提供额外的教学支持，而不仅仅是在指定的上课时间或办公时间。该项目的结果正在通过形成性和终结性措施进行严格评估，以确定它们对学生学习的影响。概念测试和屏幕播放可通过互联网获得，项目结果正通过各种场所广泛传播。

Engineering - Chemical (53)Through this project, Conceptests and Screencasts are being developed in support of six fundamental courses in chemical engineering: material and energy balances, fluids, heat transfer, mass transfer and separations, chemical engineering thermodynamics, and chemical reaction engineering. Conceptests are multiple-choice questions that are used in class with student-operated clickers, for interactive learning through discussion with peers and instructor feedback. Similar to problems on concept inventories, Conceptests typically cover fundamental topics that are often misunderstood by students. In addition to their use as in-class exercises, Conceptests can be used for online quizzes covering assigned reading that students complete prior to class or they can be used for homework or exams in the course. Screencasts are short screen captures of material with narration by an instructor such as mathematical solutions to problems, mini-lectures, training on using new software, or discussion of strategies for solving Conceptests. Screencasts are available online and provide students with additional instructional support when they need it and not just at defined class times or office hours. The results from this project are being rigorously assessed through formative and summative measures to determine their impact on student learning. The Conceptests and Screencasts are available over the Internet and project results are being broadly disseminated through a variety of venues.
