Common Bugs in Scratch Programs
This addresses the issue of debugging for learners in Scratch, but it is incremental as it builds on existing bug detection methods.
The paper tackled the problem of bugs in Scratch programs hindering learning by identifying common bug patterns and developing the LitterBox tool to automatically detect them, with empirical evaluation showing their frequency and severity.
Bugs in Scratch programs can spoil the fun and inhibit learning success. Many common bugs are the result of recurring patterns of bad code. In this paper we present a collection of common code patterns that typically hint at bugs in Scratch programs, and the LitterBox tool which can automatically detect them. We empirically evaluate how frequently these patterns occur, and how severe their consequences usually are. While fixing bugs inevitably is part of learning, the possibility to identify the bugs automatically provides the potential to support learners
