Determine whether improved lab performance reflects stronger understanding

Determine whether increased correctness on introductory programming laboratory assignments translates into stronger underlying student understanding, rather than merely improved task completion.

Background

The longitudinal results show that later student cohorts achieved higher laboratory correctness while using fewer exact implementation forms on several constrained functions. At the same time, final-exam scores declined across the observed cohorts, creating uncertainty about whether improved submitted laboratory code reflects deeper learning. The paper notes that differences in examination questions limit direct comparisons, but identifies the relationship between assignment completion and subsequent independent understanding as unresolved.

Higher lab correctness coincided with lower final-exam scores (Section~\ref{sec:results-rq2-cohort}), raising the question of whether success on the labs translates into stronger understanding.
