A Laboratory for Object-Oriented Software Development

9350708 Epstein计算机科学本科课程的目的是为学生提供高质量的专业前培训，他们中的大多数人将成为计算机的实践者。本科课程的改进强调了软件开发的以下方面：高层次抽象的严格思考，正式的规格说明和设计技术，最先进的软件开发工具的使用，以及协同工作。从Pascal所体现的过程式（或命令式）语言范式向c++和Common Lisp（带有CLOS）所体现的面向对象范式的迁移，鼓励了这些目标的实现。本项目旨在建立一个支持这些课程变化的本科生实验室。这个本科实验室使学生能够使用在UNIX平台上运行的面向对象编程环境。这些环境（特别是c++的ObjectCenter， CLOS的Allegro Composer和面向对象数据库的ObjectStore）使学生能够利用在工业中变得普遍的可视化软件工程环境。这样的环境对于面向对象系统开发尤其重要，因为在面向对象系统开发中，开发人员面临着大量相关类和交互对象的巨大复杂性。该项目还鼓励使用现代电信来支持学生之间的合作工作，学生和教师之间的电子互动，以及学生通过新闻组访问更大的知识分子社区。

9350708 Epstein The aim of the undergraduate computer science curriculum is to provide quality, pre-professional training for students, most of whom will become practitioners of computing. Improvements have been made in the undergraduate curriculum that emphasize the following aspects of software development: rigorous thinking at a high level of abstraction, formal specifications and design techniques, use of state-of-the-art software development tools, and cooperative work. Many of these objectives are encouraged by migration away from the procedural (or imperative) language paradigm embodied by Pascal towards the object-oriented paradigm embodied in C++ and Common Lisp (with CLOS). This project aims to establish an undergraduate laboratory that supports these curriculum changes. This undergraduate laboratory enables students to use object-- oriented programming environments running on the UNIX platform. These environments (specifically, ObjectCenter for C++, Allegro Composer for CLOS and ObjectStore for object-oriented data- bases) enable students to utilize the sort of visual software engineering environments that are becoming commonplace in industry. Such environments are especially important for object-oriented systems development where developers are confronted with the enormous complexity of large numbers of related classes and interacting objects. This project also encourages the use of modern telecommunications to support cooperative work among students, electronic interaction between students and faculty, and student access to the larger intellectual community over newsgroups.
