This project is reforming the mathematics program by dividing the curriculum of the second level developmental mathematics course into two courses. The decision to restructure the curriculum is based on an analysis of students' difficulties in successfully completing the extensive content to be covered in this course in a semester of only 12 weeks and the fact that the success rate in upper-level courses indicates that even students who pass may be in jeopardy in precalculus and calculus. In addition, in the present structure, students receive no college-level algebra instruction prior to precalculus. While the department has had significant success in infusing new teaching methodologies in precalculus and calculus resulting in significantly higher pass rates, hundreds of students never make it to these upper-level courses because of their poor preparation. The department is using this project to do a better job of preparing the vast majority of students who start out in developmental mathematics for upper-level precalculus and calculus courses. Central to this project is the transformation of sections of these developmental courses along with sections of precalculus and calculus into multimedia laboratory courses where students work individually and in small groups on state-of-the-art, interactive, CD-ROM-based instruction, supported with accompanying texts that contain exploratory environments, video clips, simulations, explanations, and exercises. Using this new technology, students work on modules at their own pace, taking proficiency exams when they are ready. The self-paced nature of the new CD-ROM technology makes better use of the additional time students have in this course.

本课题对数学课程进行改革，将二级发展性数学课程分为两门课程。我们之所以做出课程调整的决定，是因为我们分析了学生很难在短短12周的时间内完成这门课程所要涵盖的广泛内容，同时也考虑到高级课程的成功率表明，即使学生通过了微积分预科课程和微积分课程，他们也可能处于危险之中。此外，在目前的结构中，学生在微积分预科之前没有接受大学水平的代数指导。虽然该系在微积分预科课程和微积分课程中引入新的教学方法取得了显著的成功，从而大大提高了通过率，但仍有数百名学生由于准备不足而无法进入这些高级课程。系里正在利用这个项目来更好地为绝大多数刚开始学习发展数学的学生准备高级微积分预科和微积分课程。该项目的核心是将这些发展性课程以及微积分预科课程和微积分课程转变为多媒体实验课程，学生可以单独或以小组形式进行最先进的、交互式的、基于cd - rom的教学，并辅以包含探索环境、视频剪辑、模拟、解释和练习的附带文本。使用这种新技术，学生可以按照自己的节奏学习模块，准备好后再参加技能考试。新CD-ROM技术的自定进度特性可以更好地利用学生在本课程上的额外时间。
