If You Can’t Get Them to the Lab: Evaluating a Virtual Study Environment with...
summary
OLab provides a browser-based virtual container with a full desktop and IDE, records source code plus events like copy/paste and mouse clicks, and uses participant-specific tokens for secure access. Evaluation includes a cognitive walkthrough, a supervised DevOps lab, and an unguided student study plus a 16-participant comparison on a crypto-API task. Results show similar task performance to a download setup but greater accessibility and control over study variables, lower setup overhead, and positive participant feedback.
