This work will produce a greatly needed, major revision of the first sequence in Computer Science. Business and industry are not satisfied with the current graduates of Computer Science Programs. They need graduates who are 1) fully capable of working in teams, 2) understand problem solving and how the solution fits into the environment of the organization, and 3) possess a thorough understanding of object-oriented analysis, design and implementation. In order to prepare students to meet these requirements we propose to have them begin in the very first course to work together in teams, to look at realistic problems, and develop top-down problem solutions. To implement this solution the current bottom-up orientation of the beginning sequence will be replaced by a top-down approach. Students will be introduced to problem solving with objects which are available to them. Only later will they learn to modify and still later to create their own objects. Currently students spend most of their initial course on the syntax and semantics of the language they are using to implement the solutions to algorithms they develop. Most of their time is consumed in developing a fluency in a particular language. We propose a true top down, object-oriented, collaborative approach for students in the first course. We will develop a library of objects, detailed notes for students, and laboratory exercises to support this top down, active, collaborative learning.

这项工作将对计算机科学中的第一个序列进行急需的重大修订。商界和工业界对当前计算机科学项目的毕业生并不满意。他们需要具备以下能力的毕业生：1）完全有能力进行团队合作，2）了解问题解决以及解决方案如何适应组织环境，3）对面向对象的分析、设计和实现有透彻的了解。为了让学生做好满足这些要求的准备，我们建议他们从第一门课程开始就以团队形式合作，研究现实问题，并制定自上而下的问题解决方案。 为了实现该解决方案，当前的开始序列的自下而上的方向将被自上而下的方法所取代。将向学生介绍如何使用可用的物体解决问题。只有稍后他们才会学会修改，然后才能创建自己的对象。目前，学生将大部分初始课程花在他们用来实现他们开发的算法解决方案的语言的语法和语义上。他们的大部分时间都花在提高某种特定语言的流利程度上。 我们在第一门课程中为学生提出了一种真正的自上而下、面向对象的协作方法。我们将开发一个对象库、学生详细笔记和实验室练习，以支持这种自上而下、主动、协作的学习。
