许多学生对计算机科学（CS）抱有不正确的观念和消极的态度。为了解决这些困难，蒂姆·贝尔和他的同事开发了一系列名为“Computer Science Unplugged”的学习活动。这些活动以有趣的方式让年轻人了解计算机科学的核心概念，而无需使用计算机。 CS Unplugged 活动在 CS 教育工作者中越来越受欢迎，并且 ACM K-12 小学课程中推荐了多项活动。 CS Unplugged 在全球范围内使用，并已被翻译成多种语言。
我们研究了 CS Unplugged 活动对中学生对 CS 的看法以及他们在高中考虑和学习 CS 的愿望的影响。结果表明，活动结束后，学生对CS的认识得到了部分提高，但学习CS的欲望有所降低。
为了对这些结果提供可能的解释，我们分析了 CS Unplugged 活动，以确定这些活动在多大程度上实现了 CS Unplugged 的目标。此外，我们还检查了这些活动是否是根据建构主义原则设计的，以及它们是否与计算机科学的中心概念明确相关。我们发现，活动中只涉及了部分目标，活动没有涉及学生的先验知识，并且大多数活动没有与计算机科学的中心概念明确联系起来。我们提供修改 CS Unplugged 活动的建议，以便他们更有可能实现其目标。
Many students hold incorrect ideas and negative attitudes about computer science (CS). In order to address these difficulties, a series of learning activities called Computer Science Unplugged was developed by Tim Bell and his colleagues. These activities expose young people to central concepts in CS in an entertaining way without requiring a computer. The CS Unplugged activities have become more and more popular among CS educators and several activities are recommended in the ACM K-12 curriculum for elementary schools. CS Unplugged is used worldwide and has been translated into many languages.
We examined the effect of the CS Unplugged activities on middle-school students’ ideas about CS and their desire to consider and study it in high school. The results indicate that following the activities the ideas of the students on what CS is about were partially improved, but their desire to study CS lessened.
In order to provide possible explanations to these results, we analyzed the CS Unplugged activities to determine to what extent the objectives of CS Unplugged were addressed in the activities. In addition, we checked whether the activities were designed according to constructivist principles and whether they were explicitly linked to central concepts in CS. We found that only some of the objectives were addressed in the activities, that the activities do not engage with the students’ prior knowledge and that most of the activities are not explicitly linked to central concepts in CS. We offer suggestions for modifying the CS Unplugged activities so that they will be more likely to achieve their objectives.
