一句话：通过五天项目式 Scratch 工作坊与评分量规，评估 K-6 学生能否习得并运用基础软件开发实践。
该文关注如何向 K-6 阶段（约 10-12 岁）零编程经验的学习者有效传授软件开发技能，并评估其学习效果。研究在智利大学计算机实验室开展为期五天的课外项目式工作坊，参与者在高年级计算机专业学生指导下完成动手活动，并使用 Scratch 开发一个小型软件应用。为评估学习者对软件开发实践的掌握情况，作者设计并校准了一套评分量规，用于分析工作坊参与者生成的软件作品。该研究属于描述性案例研究。结果表明，向该年龄段学习者传授初步软件工程概念是可行的，这些概念可以用非技术语言组织，并能被新手开发者接受；同时，在性别和社会经济地位方面未观察到显著差异。
Recent literature reports a fair amount of initiatives on how to engage younger populations in achieving computational literacy. However, there is considerable less research on how to effectively deliver software development skills in a way that can be accepted and ultimately adopted by this user group. As a way to bridge this gap, we ran an extracurricular project-based workshop, targeting 10-12 years old learners with no prior coding experience, delivered over five days in the computer labs at the University of Chile. In this workshop, participants follow hands-on activities where they acquire the basics of computer programming and develop a small-scale software application using Scratch. These activities showcase that good software engineering practices can be taught to K-6 students, where these students are guided by experienced computer science undergraduate and graduate students. This paper presents a descriptive case study that focuses on assessing how K-6 learners assimilate and use these practices when developing their first computing application in a non-traditional learning experience. In order to do this, we designed and calibrated a rubric to evaluate the software products generated by the workshop participants. Our findings provide further evidence that it is indeed possible to teach initial notions of software engineering to this user group, structuring these constructs in a non-technical language that can be assimilated by novice developers. Furthermore, we did not observe significant differences in this matter according to gender and socio-economic status.
