随着全国许多学区在K-8阶段整合计算机科学(CS)和计算思维(CT)教学,研究人员仔细检查程序表达与学生理解之间的关系至关重要。在这项研究中,我们提出并报告了我们对Scratch字谜游戏的使用,这是一个学生表演Scratch脚本而其他人构建它们的游戏。Scratch Charades的目的是让学生熟悉脚本和块,而不需要复杂的用户界面的认知开销。然而,在这项研究中,我们也用它来引出学生对Scratch块和脚本的理解,以设计助记符来帮助学生调试他们的代码。根据我们的观察,我们提出了两种构建和/或调试策略。
With many school districts nationwide integrating Computer Science (CS) and Computational Thinking (CT) instruction at the K-8 level, it is crucial researchers closely inspect the relationship between program expression and student understandings. In this study, we propose and report on our use of Scratch Charades, a game in which students act out Scratch scripts while others build them. The purpose of Scratch Charades is to familiarize students with scripts and blocks without the cognitive overhead of the complex user interface. However, in this study, we also used it to elicit student understandings about Scratch blocks and scripts to design mnemonics to help students debug their code. We propose two building and/or debugging strategies based on our observations.
