Jan 1, 2026January 2026 — OpenDSA: Implemented Exercise Widget improvements by integrating CodeWorkout points and accessibility enhancements. The widget now dynamically displays points per exercise, improving user engagement and progress tracking. The change centers on accessibility (keyboard navigation and screen reader support) and a focused commit that documents the work. This delivery enhances gamified learning applicability, increases user interaction, and supports inclusivity in the OpenDSA project.

Oct 1, 2025In October 2025, OpenDSA/OpenDSA delivered a CodeWorkout progress tracking endpoint and widget enhancements, restructured documentation for module 1.02, and prepared the system for staging testing to improve user experience and evaluation readiness. Implemented learner personalization by adding a proficiency-based fetch parameter (check_proficiency=true) to tailor exercise lists. Fixed widget completion status by switching to complete_flag in postprocessor.py to ensure accurate progress reflection. These changes improve user engagement, data accuracy, staging readiness, and overall learning effectiveness.

Jul 1, 2025July 2025—OpenDSA/OpenDSA: Focused on analytics-ready improvements while preserving stability. Implemented a scroll depth tracking integration for Canvas LTI and standalone OpenDSA environments, including a two-scroller approach and continuous scroller maintenance to adapt to Canvas resizing. Refactored the feature to limit scope to the standalone OpenDSA environment to reduce risk. Documented Canvas LTI limitations in code to guide future work and prevent regressions. In response to Canvas LTI constraints, removed the scroll depth tracking feature to avoid negative user experiences and logging inaccuracies, ensuring a stable release with a clear path for rework when constraints are addressed.

Jun 1, 2025June 2025: Implemented scroll depth tracking in the RST footer for OpenDSA/OpenDSA to measure and log user engagement. The feature uses the $.scrollDepth plugin with configurable minHeight, elements, percentage, userTiming, pixelDepth, and nonInteraction, and reports metrics via ODSA.UTILS.logUserAction. Initialization wired in config_templates.py. This enables data-driven UX improvements and clearer understanding of footer visibility. No explicit major bugs fixed this period; focus on feature delivery and stability.
