Practice Drill: Classify understanding and mastery levels

• Related goal: Current Goal
• Skill / subskill: Distinguish understanding from mastery, then identify the best-supported level of mastery from evidence.
• Starting level: unknown
• Timebox: 8 minutes

Performance condition

Without opening the distilled note, classify each case below. For each one, write:

1. whether it demonstrates understanding, mastery, both, or neither;
2. the highest level supported by the evidence (1–6); and
3. one sentence explaining why the evidence does not justify a higher level.

Cases

1. A learner can define opportunity cost accurately but cannot analyse a new purchase decision.
2. A learner solves ten standard percentage problems correctly without notes, but has not worked on word problems with unfamiliar wording.
3. A learner explains why a larger mass has less acceleration when net force is fixed, and correctly predicts what happens when the mass doubles.
4. A learner fixes an unfamiliar spreadsheet formula error, explains the cause, and teaches a colleague how to avoid it.

Success criteria

• Does not treat recall alone as mastery.
• Distinguishes explanation/prediction from independent repeated performance.
• Uses “transfer” only when the case includes a genuinely changed or unfamiliar context.
• States an evidence-based reason for withholding a higher level.
• Uses the terms understanding, independent proficiency, and transfer consistently.

Common error to watch

• Assigning the highest possible level because a learner performed one impressive action, without checking whether the performance was repeated, independent, or transferable.

Next-step rule

• If all criteria are met: apply the same hierarchy to one real skill the learner is currently studying.
• If partly met: compare one pair of cases that differ only in whether the learner has a prompt or can transfer to a changed condition.
