Computer Science (31)An undergraduate education is a critical link between high school and a society increasingly dependent upon computer technology. SMET majors increasingly need computer programming as a fundamental skill. Students effectively learn computer programming by using examples, yet the number of examples that can be presented in class and in a textbook is limited. The cognitive approaches of collaborative and discovery learning supported by the intellectual scaffolding of a robust set of examples can give students a deep understanding of concepts they discover on their own. Assignment of computer programming problems just beyond a student's current skill level functions as the 'leading question', where carefully constructed examples give the student the information necessary to construct a mental model leading to the solution to the problem. This can help overcome the cognitive bottleneck where too few students negotiate the transition from lower-level skills to higher-level skills, from basic rote memorization and re-telling skills to more abstract knowledge synthesizing and transforming skills.The difficulty lies in getting a complete set of the right examples. This project creates a web-based system which gives intuitive access to between 300 and 500 examples illustrating the main points in the C++ programming language. A prototype is being implemented in a pilot study over two years, being used with 300 undergraduate students taking an introductory programming course at UIC. Evaluation will use both web-based statistics and evaluation forms, comparing student skill levels and attitudes before and after the system's implementation.

本科教育是连接高中和日益依赖计算机技术的社会的关键一环。SMET专业越来越需要计算机编程作为一项基本技能。学生通过使用示例有效地学习计算机编程，然而，在课堂上和教科书中展示的示例数量是有限的。协作和发现学习的认知方法由一组强大的例子的智力框架支持，可以让学生对他们自己发现的概念有深刻的理解。超出学生当前技能水平的计算机编程问题的作业作为“引导性问题”，其中精心构建的示例为学生提供必要的信息，以构建导致问题解决的心理模型。这有助于克服认知瓶颈，因为很少有学生能够从较低水平的技能过渡到较高水平的技能，从基本的死记硬背和复述技能过渡到更抽象的知识综合和转化技能。困难在于找到一整套正确的例子。这个项目创建了一个基于web的系统，可以直观地访问300到500个例子，说明c++编程语言的要点。在两年多的时间里，一个原型正在试点研究中实施，在UIC学习编程入门课程的300名本科生中使用。评估将使用基于网络的统计数据和评估表格，比较系统实施前后学生的技能水平和态度。
