The Design and Use of an Interactive Laboratory for CS1 and CS2

这项建议的目的是为学生提供一间教室， 进行CS1和CS2封闭实验室的目的 课程 所要求的设备包括IBM兼容486 微型计算机和支持硬件和软件，如Novell Netware、激光打印机、Microsoft Windows和Turbo 在这个教室里进行的实验练习 将遵循入门编程实验室的模式， 出现在文学作品中。 然而，这些实验室将 在以下意义上的交互：GUI shell程序将 指导学生完成实验室的任务和活动， 提供对所需资源（如编译器）的访问， 示范项目。 学生将与这个shell进行交互 以标准的方式，通过诸如图标，按钮， 建议者认为这种新环境将是 对学生来说更有吸引力和刺激性， 帮助招聘和保留潜在的专业， 计算机科学 每个shell程序都是一个独立的 Windows应用程序，因此可由教师按原样使用 在其他机构。作者建议发展一个 面向对象的框架，支持快速，高效 这些实验室外壳应用程序的编码。 该框架将 捕获shell应用程序的设计以及 他们所依据的模式。 以最少的知识， 教师可以使用该框架开发交互式实验室 根据自己的学生群体和兴趣定制的练习。 此外，该框架还可用于开发实验练习 其他CS课程也是如此。因此，该实验室框架将 这是一个重大的贡献， 技术.

The objective of this proposal is to equip a classroom for the purpose of conducting closed laboratories for CS1 and CS2 courses. The equipment requested includes IBM compatible 486 microcomputers and support hardware and software such as Novell Netware, a laser printer, Microsoft WIindows, and Turbo Pascal.The laboratory exercises conducted in this classroom will follow the model for introductory programming labs which has emerged in the literature. However, these labs will be interactive in the following sense: A GUI shell program will guide students through the tasks and activities of the lab, providing access to required resources such as compilers and demonstration programs. Students will interact with this shell in the standard way, via controls such as icons, buttons, menus, etc. The proposers believe this new environment will be significantly more engaging and stimulating for the student, aiding the recruitment and retention of potential majors in Computer Science. Each shell program would be a free-standing Windows application, and thus can be used as is by instructors at other institutions.The authors propose development of an object-oriented framework to support the quick and efficient coding of these lab shell applications. This framework would capture the design of the shell applications as well as the model upon which they are based. With minimal knowledge, other instructors could use the framework to develop interactive lab exercises customized to their own student body and interests. Moreover, the framework could be used to devlop lab exercises for other CS courses also. Thus, this lab framework would represent a significant contribution to instructional technology.
