A Dynamic Computer Science Laboratory

一个新的正式的实验室环境， 计算机科学课程开发。 基础设施 对于这种环境和重点的努力， 项目是一个独特的软件系统，DYNALAB，支持 在计算机科学中进行广泛的实验。 DYNALAB 包括一个综合图书馆， Pascal程序、程序动画和用户界面， 使DYNALAB易于新手使用。 学生的 从库中检索程序并通过 程序动画师。 相关的程序执行动态是 在用户控制下显示，包括当前行 执行、变量和参数值、递归堆栈 机制、语句计数、存储器单元计数等。 DYNALAB是计算机科学的国家模型 开始将正式的 实验室纳入入门课程。 一系列 充满基于DYNALAB的实验室手册 和DYNALAB本身就是这个项目的产物。

A new formal laboratory environment for the introductory computer science curriculum is developed. The infrastructure for this environment and the focal point of the effort on this project is a unique software system, DYNALAB, that supports extensive experimentation in computer science. DYNALAB consists of a comprehensive library of expertly constructed Pascal programs, a program animator, and a user interface that makes DYNALAB accessible to the novice. Students are able to retrieve programs from the library and execute them through the program animator. Pertinent program execution dynamics are displayed under user control, including current line of execution, variable and parameter values, recursive stack mechanisms, statement counts, memory cell counts, and others. DYNALAB serves as a national model for computer science departments that are beginning to incorporate formal laboratories into the introductory curriculum. A series of laboratory manuals replete with experiments based on DYNALAB and DYNALAB itself are the products of this project.
