Computer Science (31) This project is developing a pedagogical tool that trains introductory computer-programming students in using top-down design with abstraction refinement. The tool also allows students to use the bottom-up approach to utilize previously solved modules. This system helps students to develop sound problem solving skills at the earliest stages of training. Specifically, this online tutoring system provides a personalized assistant for understanding the algorithm refinement process. Students can reinforce these problem solving skills by using the tutor to solve a number of specific problems.The proposed project extends a previously developed online tutoring system for laboratories for introductory computer science courses to include tutoring for top-down design concepts. Solutions to selected problems are represented at multiple levels of abstraction. Alternative solutions are represented, again at varying levels of abstraction, as are "dead-ends" and other erroneous solutions. Solutions to related problems are also encoded. Collectively, this precompiled knowledge forms an abstraction network. The abstraction network allows students the flexibility to design their own solutions to problems. In addition, it permits students to follow faulty paths so that they can discover the implications of earlier design choices and learn from their mistakes.

计算机科学（31）该项目正在开发一种教学工具，该工具训练介绍性的计算机编程学生，使用自上而下的设计和抽象精致。该工具还允许学生使用自下而上的方法利用先前解决的模块。该系统可帮助学生在培训的最早阶段发展声音解决问题的技能。具体而言，该在线辅导系统提供了一个个性化的助手，以了解算法改进过程。学生可以通过使用导师解决许多特定问题来增强这些解决问题的技能。拟议的项目扩展了一个先前开发的在线辅导系统，用于实验室，用于入门计算机科学课程，包括用于自上而下的设计概念的辅助。选定问题的解决方案在多个抽象级别表示。替代溶液在不同水平的抽象水平上再次表示，“死胡同”和其他错误的解决方案也是如此。有关相关问题的解决方案也已编码。总体而言，这种预编译的知识形成了一个抽象网络。抽象网络使学生可以灵活地设计自己的解决方案，以解决问题。此外，它允许学生遵循错误的道路，以便他们可以发现早期设计选择的含义并从错误中学习。
