Sep 1, 2025September 2025 monthly summary for maths/moodle-qtype_stack. Focused on delivering deeper analytics, robust plugin health, improved question management and UI polish, all contributing to better instructor decision-making, admin efficiency, and system reliability. Key features delivered: - Enhanced response analysis and reporting: includes all student attempts per question in reports; updated summarise_response_json to accept metadata; adjusted queries to fetch all relevant attempt steps for richer, actionable insights. - STACK health checks enhancements and robustness: unified health checks for CAS connection and STACK-Maxima version; integrated into Moodle admin settings; environment-aware checks and conditional handling for settings. - Question administration UI/version consistency: ensured latest version is loaded and displayed consistently in the Stack question admin UI, reducing admin confusion. - Question tidying enhancements with version warning: added version warning in tidying workflow; guides admins to update the latest version and links to edit in the question bank when creating a new version. - Question editing/preview enhancements and latest version retrieval: improved editing/preview workflow; refactored links for running tests, previews, and editing the latest version; added a function to retrieve the latest version of a question. - HELM parts list UI styling improvements: CSS/UI refinements to improve first paragraph display, alignment across devices, and general cleanup. Major bugs fixed: - Test stability fix for Behat analysis page: made quiz and question selection deterministic to reduce intermittent Behat failures. - Robust download without a question attempt: corrected download path by invoking get_database_id on the qa object to prevent errors when STACK is used without a question attempt. - Response tree first node safety fix: guards to ensure first node exists before use; added tests for invalid/missing first nodes. Overall impact and accomplishments: - Stronger analytics: richer, more reliable response data enables better instructional decisions and student insights. - Increased reliability: robust health checks and deterministic tests reduce production incidents and maintenance effort. - Admin efficiency: version consistency and streamlined editing improve governance and reduce admin errors. - UI/UX polish: targeted styling improvements across HELM components improve readability and accessibility on all devices. Technologies/skills demonstrated: - PHP/Moodle plugin development, SQL/query optimization, and data shape changes for richer reporting. - Behat test stabilization and deterministic test design. - Environment-aware health checks and robust error handling. - UI/CSS refinements and frontend workflow improvements; version management for question assets. Business value: - Enables instructors to derive richer insights from per-attempt data, reduces admin confusion in versioning, improves system reliability, and delivers a cleaner, more maintainable codebase for ongoing STACK integration.
