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依赖于基于软件的系统，软件质量不仅严重影响软件应用程序的实用性，而且还影响其安全性。目前，标准计算机科学（CS）课程很晚才向计算机学习者介绍这一关键概念，或者完全忽略了它。为了解决这个问题，该项目从根本上重新思考软件质量教学的过程和实践，以从头开始促进质量文化。该项目通过基于专业软件工程实践（称为“代码重构”）的质量控制开发软件和相关教材，探索教学软件质量和编程基础知识。这种教育干预服务于国家利益，提供了一种简单的途径，将经过验证的、真实的软件工程实践引入计算机科学入门课程，向新手程序员传授遵循原则性软件工程实践的重要性。该项目将建立在基于块的编程的成功和流行之上，这是一种针对入门学习者的高效教学工具。研究团队将研究基于块的编程背景下的软件质量，以及如何引入经过验证的、真实的软件工程实践重构（一种可以提高代码和设计质量的语义保留程序转换）来促进计算机科学入门课程中的质量文化。该项目将开发一种新颖的教育干预措施，向入门学生教授软件质量概念，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创建重构的概念基础，具体实现为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所开发的教育干预措施，以确定其在培养提高软件质量所需的学生知识、技能和实践方面的有效性。
