STACK q-type Analytics

Added German, Italian, and Spanish string translations

Question Analytics is simpler now. Instead of six separate tables to dig through, you get one clear "Question Response Overview" chart showing how students did on each question at a glance.

Question Review shows real formatting. Question text now displays with proper bullet points, code, and layout, matching what students actually saw, instead of jumbled plain text.

Fixed a confusing display bug where students who left a question blank used to show up with a cryptic internal code (e.g. "Seed: 123; prt1: !"). It now just says "(No response)".

Quiz Snapshot replaces the old summary table. This is a clean, compact view of overall average, attempts, and how many students are still in progress vs. finished.

Student names in Model Analytics now link to their Moodle profile. Clicking a name in the "at-risk" table to jump straight to that student.

Cleaner, more consistent labels and headings throughout the analytics pages.

Diagnostics Analytics is temporarily off the main menu while it's being redesigned. Nothing was removed, and it's still reachable directly if you have the link.

Renamed the course-wide section to Student Quiz Summary.
Changed the table to one row per student per quiz.
Added attempt count, first grade, and latest grade.
Linked each student name to Moodle's review page for the latest attempt.
Made review links open in a new tab.
Removed Completed On and Started On from the summary table.
Moved grade comparison controls into the scatter plot.
Made the scatter plot update without reloading the page.

Maturity bumped to Stable. Updated the time fetch notice for longer courses.

This release improves reliability and readability across the plugin. Quiz Analytics and Question Analytics, previously slow or timing out on large courses, now load in seconds through batched queries, background processing, and caching, verified against real courses with tens of thousands of attempts. Several real bugs were fixed along the way, including a severe Model Analytics slowdown and a parsing bug that misread certain STACK inputs as blank. Multi part question text and error drill downs now show clear line breaks instead of running together, course wide charts now plot quizzes in the order they were taught, and wide charts now print correctly in the PDF export. Every section of the plugin now shares the same layout, wording, and plain sentence style throughout.

Fixed a Cloudflare 524 timeout bug with large courses. Fixed named STACK inputs being misread as blank. Renamed display name to "STACK q-type Analytics".

Internal housekeeping release: no functional or UI changes. Aligns the plugin's internal component identifier with this Marketplace listing so future versions install as an update rather than a separate plugin.

Fixed hard-coded language strings and missing language string definitions.

Initial release. Everything runs as plain PHP inside the plugin itself — no separate service to deploy, no external dependency beyond PHP.

• Course-wide cross-quiz comparison (grade distribution, engagement over time, attempts-vs-grade scatter, per-quiz stats and trend lines) across every STACK quiz in a course.


• Per-quiz Question Analytics: difficulty and discrimination indices, response distribution, a per-question error drill-down, a student performance matrix, and consolidated question metrics.


• Per-quiz Solution Process Visualization: class-wide PRT answer transition graphs, per-node network centrality, PRT/tree-edit-distance 3D distance charts, and a cross-attempt comparison with a clickable per-student drill-down.


• Generate PDF Report on every view, with section checkboxes, a colorblind-mode toggle, and an anonymize-student-data toggle (replaces real names/emails with stable per-student pseudonyms, consistent across every table, chart, and PDF) — charts are captured client-side from the already-rendered page and embedded into a PHP-generated PDF (TCPDF).


• Reachable from a course's secondary navigation, and from an Analytics link this plugin adds to each STACK quiz's own settings menu.


• Colorblind-safe chart palettes throughout.
