Mapping a Learning Trajectory and Student Outcomes in Unplugged Coding
This thesis reports the outcomes of a mixed methods exploratory study on young children’s spatial reasoning and mathematics involving unplugged (offline) coding with young children (JK-Grade 2). Intrigued by the increased push for coding in schools, teachers and researchers worked together in a collaborative research process to design a sequence of unplugged coding activities and document student thinking. Qualitative results include the mapping of a hypothetical learning trajectory for unplugged coding focused on location and movement, as well as an analysis of the computational, spatial and mathematical thinking in unplugged coding. The grid was found to be a fundamental spatial structure that supported student thinking across all domains. Quantitative data included a range of spatial and mathematics measures that were administered pre-post with a subsample of 55 students. Findings showed strongest gains in mental rotations/visualization and magnitude comparison, suggesting this as a promising area for further study.
