Design as an Introduction to Computer Science in High School

计算机编程在小学和高中已经非常普及， 中学教育，因为它一直是一个强大的工具， 孩子们可以发展解决问题的能力， 数学、物理学和物流学的基本概念， 对计算机科学有很好的基础理解。 不幸的是，评估这些说法的研究发现， 学生未能获得足够的编程能力， 作为一般问题解决技能发展的基础。 此外，专家的研究和实践经验， 软件设计者建议， 领域和软件总体方案的设计 比学习编码更重要。 学习强调设计的编程课程的学生 比其他课程的学生，但他们仍然表现出很少的进步 解决一般问题。 最近开发的技术 简化了分析和设计阶段之间的关系， 使其能够在没有第一次的情况下教学生软件设计， 教他们如何编码。 这个项目建议教设计 没有编码，并严格评估这种 approach. 如果成功，这个项目将成为一个模式， 可以为计算机科学入门课程开发， 计算机扫盲课程。

Computer programming has gained great popularity in elementary and secondary education because it has been as a powerful tool by which children can develop general problem solving skills and learn fundamental concepts in mathematics, physics, and logistics, as well acquiring foundational understanding of computer science. Unfortunately, research assessing these claims has found that students fail to attain sufficient programming competence to serve as a basis for the development of general problem solving skills. In addition, both research and the practical experiences of expert software designers have suggested that the analysis of the problem domain and the design of an overall plan of the software are more central to the development of software than is learning to code. Students in programming courses that emphasize design learn more than students in other courses, but they still show little progress toward general problem solving. Recently developed technology has simplified the relation between the analysis and design phase, making it feasible to teach students software design without first teaching them how to code. This project proposes to teach design without coding and to evaluate critically the efficacy of such an approach. If successful, this project will serve as a model that can be developed both for introductory computer science courses and for computer literacy courses.
