marimo-learn 0.12.0

marimo learning utilities

marimo-learn

Formative assessment widgets for marimo notebooks.

Installation

pip install marimo-learn

Usage in marimo

from marimo_learn import FlashcardWidget, MultipleChoiceWidget, OrderingWidget
from marimo_learn import MatchingWidget, LabelingWidget, ConceptMapWidget

Each widget is an anywidget component. Pass the configuration as constructor arguments; the widget syncs state back to Python via the value traitlet.

Standalone JavaScript bundle

The widgets are also published as an npm package:

npm install marimo-learn

Or load the bundle directly in HTML:

<script type="module" src="marimo-learn.js"></script>

The bundle auto-mounts any .marimo-* divs it finds in the page (see HTML configuration below). You can also call the render functions manually:

import { renderFlashcard, renderMultipleChoice, renderOrdering,
         renderMatching, renderLabeling, renderConceptMap } from 'marimo-learn';

renderMultipleChoice(document.getElementById('target'), {
  question: 'What is 2 + 2?',
  options: ['3', '4', '5'],
  correct_answer: 1,
  lang: 'en',
});

HTML configuration

When the bundle is loaded, autoMount() scans the page for divs with the class marimo-<widget>, parses the HTML markup inside each div, and replaces it with a live widget. This lets you author exercises in plain HTML or Markdown.

Multiple choice

<div class="marimo-multiple-choice" data-correct="2">
  <p>Question text</p>
  <ol>
    <li>Option A</li>
    <li>Option B</li>
    <li>Option C (correct — zero-based index matches data-correct)</li>
    <li>Option D</li>
  </ol>
</div>

• data-correct — zero-based index of the correct option (required)
• data-lang — language code, default en

Flashcard

<div class="marimo-flashcard">
  <p>Deck title (optional)</p>
  <dl>
    <dt>Front of card 1</dt>
    <dd>Back of card 1</dd>
    <dt>Front of card 2</dt>
    <dd>Back of card 2</dd>
  </dl>
</div>

Cards are shuffled automatically. data-lang sets the language (default en).

Ordering

<div class="marimo-ordering">
  <p>Question text</p>
  <ol>
    <li>First step (correct position)</li>
    <li>Second step</li>
    <li>Third step</li>
  </ol>
</div>

The <ol> lists items in the correct order. The widget shuffles them before presenting them to the student. data-lang sets the language (default en).

Matching

<div class="marimo-matching">
  <p>Question text</p>
  <table>
    <tr><td>Left item 1</td><td>Right item 1</td></tr>
    <tr><td>Left item 2</td><td>Right item 2</td></tr>
    <tr><td>Left item 3</td><td>Right item 3</td></tr>
  </table>
</div>

Each row defines a matched pair. The right column is shuffled automatically. data-lang sets the language (default en).

Labeling

<div class="marimo-labeling">
  <p>Question text</p>
  <table>
    <tr><td>Text line 1</td><td>Label name</td></tr>
    <tr><td>Text line 2</td><td>Label name</td></tr>
    <tr><td>Text line 3</td><td>Label A, Label B</td></tr>
  </table>
</div>

Column 1 is the text to label; column 2 is the correct label name. Multiple correct labels for one line are written as a comma-separated list. The available label set is derived automatically from the unique names in column 2. data-lang sets the language (default en).

Concept map

<div class="marimo-concept-map">
  <p>Question text</p>
  <table>
    <tr><td>Source node</td><td>relationship</td><td>Target node</td></tr>
    <tr><td>Node A</td>    <td>leads to</td>    <td>Node B</td></tr>
    <tr><td>Node B</td>    <td>leads to</td>    <td>Node C</td></tr>
  </table>
</div>

Each row defines one correct directed edge: source → label → target. The node list and term list are inferred automatically from the table in first-appearance order. data-lang sets the language (default en).
