Algorithm Question Type

A quiz question in which the student draws an algorithm as a flowchart and can run it before submitting. With tests, the answer is graded automatically.

Features

• Draw the algorithm with the same editor as in TinyMCE, with Run / Step, variable watch and generated code.
• Runnable review: the teacher can run and step through the submitted diagram while grading.
• Automatic grading: the teacher enters only the test inputs; the expected outputs are computed from the teacher's solution. Without tests the answer is graded manually.
• Hidden tests and required structures (If, For, While, Do loop, array).
• Analyse an algorithm: put an interactive diagram in the question text (needs filter_algorithm).

What's new in 1.2.0

• Renaming a function in the answer also renames every call of it (tiny_algorithm 1.2.0).
• The CSS classes of the editor carry the plugin name, so they cannot clash with the theme.

Requirements

• Moodle 4.5 LTS to 5.3 (PHP as required by your Moodle version; tested on all of them).
• The tiny_algorithm plugin, version 1.2.0 or newer; filter_algorithm is optional (interactive diagrams in question text).

Privacy

The student's answer is stored by the Moodle question engine like any other answer; the diagram runs in the browser and, for automatic grading, on your Moodle server; nothing is sent to external services. Test inputs and options are stored with the question. The plugin implements the Moodle Privacy API.
