How it works

A well-formed learning objective follows the ABCD model: Audience, Behavior (an observable verb from Bloom's Taxonomy), Condition, and Degree. Bloom's Taxonomy ranks cognitive demand from concrete recall to open-ended creation:

Remember → Understand → Apply → Analyze → Evaluate → Create
(low cognitive load)              (high cognitive load)

This simulator models predicted mastery as a logistic function of how clearly the objective is written and how well the assessment matches its verb and level, discounted by the level's intrinsic difficulty:

difficulty = (level_index + 1) / 6
z = 3.6·specificity + 3.2·alignment − 3.0·difficulty − 1.6
mastery = 1 / (1 + e^-z)

Level buttons — choose the cognitive demand the objective targets; each has its own verb and sits at a different height on the taxonomy pyramid.
ABCD specificity — how completely the objective states condition and degree, not just a bare verb. Vague objectives ("understand X") predict lower, harder-to-assess mastery than precise ones ("given a dataset, classify X with 90% accuracy").
Assessment alignment — how closely the test item's cognitive demand matches the objective's verb (a multiple-choice quiz poorly measures a "Create" objective).
Run cohort — launches a virtual class up the pyramid to the chosen level; each student's own outcome is drawn from the mastery probability, so the visual pass/fail split mirrors the number.

Real-world relevance: this ABCD + Bloom framework is the standard instructional-design model used to write curriculum learning objectives and to check that assessments actually measure what the objective claims to teach.
