Providing formative feedback on heavy cognitive tasks, such as modelling sequence diagrams, is important for novices to improve learning outcomes. However, reduced face-to-face contact since the advent of COVID-19, has made it difficult to give the feedback and instead made it necessary to devise pedagogical tools able to give regular formative feedback. This paper summarizes and reports the longitudinal studies undertaken to develop such a tool capable of verifying consistency, completeness and quality. This paper also reports views of experienced software engineering instructors about the effectiveness of the current pedagogical tool on improving overall learning outcomes. Based on these findings, we have proposed a number of metrics and incorporated them into our pedagogical tool. The novelty of this tool is its inherent scaffolded approach giving feedback on consistency with class diagrams, verifying responsibilities specified in use-case postconditions are discharged and generating qualitative feedback based on established metrics.
