Peek-through Customization: Example-Based In-Context Sharing for Learning Management Systems

Learning to use a learning management system (LMS) can often be complex and challenging for instructors who have little time to explore the application interface. We ran formative interviews (N=10) suggesting that instructors often prefer to consult colleagues to seek examples of customizations and their explanations. Based on our findings, we designed and developed Customizer, an in-context example-based customization sharing platform that runs atop a widely-used LMS and facilitates discovery of relevant customizations shared by peers. Customizer allows instructors to experiment with shared customizations in familiar contexts by copying their course content into on-the-fly testing environments, minimizing any risk of breaking their live course setups. Our usability evaluation (N=10) showed that most users found Customizer intuitive and useful, and that its exploratory interface was helpful in a variety of use cases. Furthermore, many participants saw potential for Customizer to improve their workflows in other applications beyond educational contexts.
