摘要

．软件正确性的形式化方法对软件工程的未来至关重要——因此必须成为软件工程教育的重要组成部分。不幸的是，形式化的方法经常受到学生的抵制，因为他们觉得困难、数学和实际无关。我们通过采用编程密集型方法重新开发了软件正确性课程，使用求解器辅助语言Dafny通过自动评估提供即时的形成性反馈。我们重新开发的课程提高了学生的保留率，并获得了至少十年来该课程的最佳评价。抽象形式建模:我们还考虑采用基于抽象形式建模的方法。高级工具，如TLA+[33]、Alloy Alloy[27]或SPIN[26]，基于这些系统的抽象模型，而不是实际的编程和源代码，支持对系统属性的推理和机械检查。很明显，这些抽象的形式化模型可以在软件工程项目中扮演重要的角色，至少在项目的早期阶段是这样。

More Programming Than Programming: Teaching Formal Methods in a Software Engineering Programme

. Formal methods for software correctness are critical to the future of software engineering — and so must be an essential part of software engineering education. Unfortunately, formal methods are often resisted by students due to perceived difﬁculty, mathematicity, and practical irrelevance. We redeveloped our software correctness course by taking a programming intensive approach, using the solver-aided language Dafny to provide instant formative feedback via automated assessment. Our redeveloped course increased student retention and resulted in the best evaluation for the course for at least ten years. Abstract Formal Modelling: We also considered taking an approach based on abstract formal modelling. High-level tools, such as TLA+ [33], Alloy Alloy [27] or SPIN [26], support reasoning and mechanised checking of systems’ properties, based on abstract models of those systems, rather than actual programming and source code. It is clear that these kinds of abstract formal models can play an important role in software engineering projects, at least in project’s the early stages,
