Calculus 1 Video Project

数学科学（21）这个概念验证项目正在开发简短的视频剪辑，解释如何做选定的家庭作业问题，涵盖微积分入门中的主要主题。这些剪辑旨在补充传统形式的支持，如辅导和复习课，特别注意减少不成功的学生（D/F/Withdraw）参加微积分的比例。这些剪辑的数字化体现促进了广泛的可访问性和重复使用。从学习者的角度来看，剪辑也提供了多种机会观看和审查。为了管理这些剪辑，正在构建一个XML/DTD管理系统，以允许以多种格式发布到各种媒体。正在沿着一项综合评估方案，以确定这些初步剪辑的有效性，并通过网络和DVD进行传播。该项目还为帮助其他数学和科学课程中可能不成功的学生提供了一个模型。

Mathematical Sciences (21) This proof-of-concept project is developing short video clips explaining how to do selected homework problems covering the primary topics covered in introductory calculus. These clips are intended to supplement traditional forms of support such as tutorials and recitation sessions with particular attention to reducing the percentage of unsuccessful students (D/F/Withdraw) taking calculus. The digital incarnation of these clips promotes wide accessibility and reuse. From the learner's perspective the clips also offer multiple opportunities for viewing and reviewing. To manage this collection of clips an XML/DTD management system is being constructed to allow publication to a variety of media, in multiple formats. Both web and DVD based dissemination is being undertaken along with a comprehensive evaluation program to determine the effectiveness of these initial clips. This project also offers a model for helping potentially unsuccessful students in other math and science courses.
