C++ For Example

计算机科学（31）本科教育是高中和社会之间的关键环节越来越依赖于计算机技术。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，但在课堂上和教科书中可以呈现的示例数量有限。协作和发现学习的认知方法由一组强大的例子的智力支架支持，可以让学生深入理解他们自己发现的概念。计算机编程问题的分配只是超出了学生目前的技能水平的功能作为“引导问题”，精心构建的例子给学生必要的信息来构建一个心理模型，导致解决问题。这有助于克服认知瓶颈，即很少有学生能够从低层次技能过渡到高层次技能，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，困难在于获得一套完整的正确的例子。该项目创建了一个基于Web的系统，可以直观地访问300到500个示例，说明C++编程语言的要点。一个原型正在两年多的试点研究中实施，正在与300名本科生一起在UIC学习入门编程课程。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。

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.
