This longitudinal study investigates the impact of an extra-curricular programming workshop in student interest development in computer science. The workshop was targeted at 12–18-year old youngsters. A survey was sent to all previous participants with a known home address; 31.5% responded the survey (n = 197). This data was then combined with pre-workshop survey data, and analyzed with mixed methods. Positive development of interest was discovered for 57% of the respondents, of which nearly all attributed their interest increase to the workshop at least partly (92%). Qualitative inspection revealed that the workshop provided three anchors that facilitated students’ reengagement with programming and development of interest: disciplinary content, a concrete artifact built by students themselves, and tools. Neutral development and interest regress were also discovered, though the impact of the workshop on these interest trajectories remains unclear.

计算机科学外展研讨会和兴趣发展：一项纵向研究

这项纵向研究调查了课外编程研讨会对计算机科学学生兴趣发展的影响。该讲习班针对12至18岁的年轻人。已向所有以前有已知家庭住址的参与者发送了调查；31.5％的人回答了调查（n = 197）。然后将这些数据与车间前的调查数据结合起来，并用混合方法进行分析。57％的受访者发现兴趣得到了积极发展，其中几乎所有受访者将其兴趣增加至少部分归因于研讨会（92％）。定性检查显示，该研讨会提供了三个促进学生重新参与编程和发展兴趣的锚点：学科内容，学生自己建造的具体人工制品和工具。
