Intelligent Algorithm Development Tutor

计算机科学(31)这个项目正在开发一个教学工具，培训计算机编程入门的学生如何使用自上而下的设计和抽象的精细化。该工具还允许学生使用自下而上的方法来利用以前解决的模块。这个系统帮助学生在培训的最早阶段培养良好的解决问题的技能。具体地说，这个在线辅导系统为理解算法求精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。拟议的项目扩展了之前为实验室开发的计算机科学入门课程在线辅导系统，包括自上而下设计概念的辅导。选定问题的解决方案在多个抽象级别上表示。可选的解决方案也是以不同的抽象级别表示的，就像“死胡同”和其他错误的解决方案一样。相关问题的解决方案也被编码。这些预编译的知识共同构成了一个抽象网络。抽象网络允许学生灵活地设计他们自己的问题解决方案。此外，它还允许学生沿着错误的路径前进，这样他们就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.
