Exploring Differences Between Student and Teacher Created Snap! Projects

This paper illustrates coding decisions by in-service teachers and high school interns working independently versus collaboratively to build computing activities for non-computing classrooms. We investigate code written in Snap! to gain insights on project type and subject matter. We also share case studies on how intern collaboration influences final product execution. Through our research, we found student-only teams often created tutorial projects whereas teachers-only teams create interactive narratives. We found students were able to reuse code across projects to replicate similar mechanics and that students specialize in different aspects of project creation. Overall, we find it beneficial to have collaborative teacher-student teams.
