Intelligent Algorithm Development Tutor

计算机科学（31）本项目旨在开发一种教学工具，用于训练计算机编程入门级学生使用带有抽象精化的自顶向下设计。该工具还允许学生使用自底向上的方法来利用以前解决的模块。这个系统帮助学生在训练的最初阶段培养解决问题的能力。具体来说，这个在线辅导系统为理解算法的改进过程提供了一个个性化的助手。学生可以通过使用导师解决一些具体问题来加强这些解决问题的技能。拟议的项目扩展了先前为实验室开发的计算机科学入门课程在线辅导系统，包括自顶向下设计概念的辅导。所选问题的解决方案在多个抽象层次上表示。在不同的抽象层次上，替代解决方案被表示为“死胡同”和其他错误的解决方案。对相关问题的解决方案也进行了编码。总的来说，这些预编译的知识形成了一个抽象的网络。抽象网络允许学生灵活地设计自己的问题解决方案。此外，它允许学生遵循错误的路径，以便他们可以发现早期设计选择的含义并从错误中学习。

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.
