项目摘要

The key functions of modern society depend on software-based systems, with software quality critically affecting not only the utility of software applications but also their safety and security. Currently, the standard computer science (CS) curriculum introduces computing learners to this key concept very late or leaves it out completely. To address this problem, this project fundamentally rethinks the process and practices of teaching software quality to promote the culture of quality from the ground up. This project explores teaching software quality alongside the fundamentals of programming, by developing software and related teaching materials based on a professional software engineering practice for quality control known as "code refactoring." This educational intervention serves the national interest by providing a simple pathway for bringing proven, real-world software engineering practices to the introductory computer science curriculum, imparting the importance of following principled software engineering practices to novice programmers.This project will build on the success and popularity of block-based programming, a highly effective pedagogical tool for introductory learners. The research team will investigate software quality in the context of block-based programming and how the proven, real-world software engineering practice of refactoring, a semantics-preserving program transformation that improves code and design quality, can be introduced to promote the culture of quality in introductory CS curriculum. This project will develop a novel educational intervention for teaching software quality concepts to introductory students, including teaching strategies and learning materials. This work will also help create a conceptual foundation of refactoring for block-based languages, concretely realized as refactoring support for block-based programming environments. Finally, the project team will systematically evaluate the developed educational intervention to determine its effectiveness in fostering student knowledge, skills, and practices, required to improve software quality.

现代社会的关键功能取决于基于软件的系统，软件质量不仅会影响软件应用程序的实用性，还影响其安全性和安全性。目前，标准的计算机科学（CS）课程将计算学习者非常迟到或将其完全遗漏。为了解决这个问题，该项目从根本上重新考虑了教授软件质量的过程和实践，以从头开始促进质量文化。该项目通过基于专业的软件工程实践开发软件和相关的教材，探索了教学软件质量以及编程的基础知识，用于质量控制“代码重构”。这项教育干预措施通过提供了一个简单的途径，可以将经过验证的现实世界软件工程实践带给入门计算机科学课程，从而赋予遵循有效的项目项目的原则性软件工程实践的重要性。该项目将基于基于块的编程的成功和普及，这是基于块的程序，是一种有效的介绍性工具，用于介绍性学习者。研究团队将在基于块的编程的背景下调查软件质量，以及可验证的，现实世界中的软件工程重构实践，即可以提高代码和设计质量的语义保护程序转换，以促进入门CS课程中的质量文化。该项目将开发一种新颖的教育干预措施，用于教授软件质量概念，以便入门学生，包括教学策略和学习材料。这项工作还将有助于为基于块的语言建立重构的概念基础，该基础是对基于块的编程环境的重构支持。最后，项目团队将系统地评估开发的教育干预措施，以确定其在促进学生知识，技能和实践中的有效性，以提高软件质量。
