STACK Quiz & Model Analytics provides interactive analytics for Moodle quizzes using the STACK (Maxima CAS) question type.

Features include:

  • Quiz Analytics: compare quiz grades, engagement, attempts, and performance trends.
  • Question Analytics: analyse difficulty, discrimination, response outcomes, student performance, and common errors.
  • Detailed response analysis: review individual student submissions alongside expected answers.
  • PDF exports, colour-blind mode, and anonymised student data.
  • One "Analytics" nav entry (reachable from a course's own navigation, and from an "Analytics" link this plugin adds directly to each STACK quiz's own settings menu) with a "Section:" switcher between all four sections at the top of every page — previously two separate plugins, now one install.
  • No external services, subscriptions, or API keys of any kind. Every computation runs in-process in plain PHP, and nothing ever leaves the Moodle server.
  • Requires `qtype_stack` (the STACK question type) to have anything to show.
