HEIG Quiz¶

An open-source learning management system built around assessment, for courses in science, technology, engineering and mathematics (STEM). Question pools with categories, concepts and published versions; evaluations run live on a server-side clock, with a projector dashboard and automatic grading, including code executed in a sandbox and circuits graded by simulation; live polls answered from a phone through a QR code; a classroom journal and spaced-repetition practice between the exams. Born at HEIG-VD and open to every school whose teachers and students hold a Switch edu-ID. One application server, one PostgreSQL, one repository, operable by one person, with the code runner on a virtual machine of its own.

What it does, in one paragraph¶

A teacher keeps questions in pools, each question with a history of published versions. An evaluation is built from published questions, drawn from the pools linked to a course, and run in a classroom whose roster was imported from a spreadsheet. The server keeps the clock: the waiting room opens, the evaluation starts, every answer is saved as it is typed, the teacher watches a live grid, extends or pauses, and closes. A grading pass proposes a grade for every answer, the teacher validates or adjusts, and releases the results: each student then reads their own feedback. A poll is the short form of the same thing: one question, thrown on the wall, answered by whoever is in the room.

The stack in one sentence¶

A Fastify monolith over PostgreSQL, a React single-page application, Switch edu-ID for identity, server-sent events keeping every open view live, code run in the browser through WebAssembly for the trial and in hardened Podman containers for the grade.
