Git is widely used for collaborative software development, but it can be challenging for newcomers. While most learning tools focus on individual workflows, Git is inherently collaborative. We present GitAcademy, a browser-based learning platform that embeds a full Git environment with a split-view collaborative mode:…

The Elephant in the Syntax: A Comparative Study of Semantics‑First, Block‑Based, and Textual Programming

Syntax remains a major barrier for novices. Although block-based systems reduce or eliminate syntax errors, conditionals still challenge learners, likely because their semantics remain implicit. In this paper, we address this problem by introducing a semantics-first, state-visible programming approach inspired by the…

Computer Science Achievement and Writing Skills Predict Vibe Coding Proficiency

Many software development platforms now support LLM-driven programming, or “vibe coding”, a technique that allows one to specify programs in natural language and iterate from observed behavior, all without directly editing source code. While its adoption is accelerating, little is known about which skills best predic…
