C++ For Example

计算机科学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纽带。SMET专业的学生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，但课堂和教科书中可以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健壮的例子组成的智力支架支持，可以让学生深入理解他们自己发现的概念。超出学生当前技能水平的计算机编程问题的布置起到了“引导性问题”的作用，精心设计的例子为学生提供了必要的信息，以构建一个心理模型，从而解决问题。这可以帮助克服认知瓶颈，因为很少有学生讨论从低级技能到高级技能的过渡，从基本的死记硬背和重述技能到更抽象的知识综合和转化技能的过渡。困难在于获得一套完整的正确例子。这个项目创建了一个基于Web的系统，它可以直观地访问300到500个用C++编程语言说明要点的例子。一个原型正在两年多的试点研究中实施，300名本科生在UIC参加编程入门课程。评估将使用基于网络的统计数据和评估表，比较系统实施前后学生的技能水平和态度。

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.
