Impact of C‐coding self‐assessment exercises on exam performance: A study in engineering education

open access: yesComputer Applications in Engineering Education, Volume 32, Issue 2, March 2024.
Abstract The Bologna process has brought about a revolution in university studies since, among other things, it encourages continuous evaluations throughout the academic period. This situation causes already depleted teaching teams to have an additional workload, so automatic tools are needed to evaluate the new assignments.
