Term assessment

Demonstrate term-2 mastery on a mixed, no-notes assessment, then complete honest error analysis.

Like the term-1 assessment, this is a measurement, not a judgment - and like any measurement, it only means something if the conditions are honest: no notes, roughly 45-50 minutes, done without hovering. The mixed order matters too; real problems do not announce which chapter they came from, so this test will not either.

The real work happens after grading: for every miss, classify it as a careless slip, a procedure gap, or a concept gap, then re-solve it cold the next day. A wrong answer you can now explain start to finish is worth more than a right one you got by luck - the goal is a mastery ledger that tells the truth about what still needs review.

📋 For the grown-up teacher
Teach it (10–15 min):
  • Build the assessment from this term's Try problems with the numbers changed, or ask the OS for a fresh generated set.
  • Keep the room calm but the conditions real: timed-ish, no notes, no rescuing mid-problem.
  • Grade together immediately - feedback while the thinking is still warm sticks far better than a score handed over the next day.
  • Log the honest results in the mastery ledger; the adaptive planner uses that truth to resurface exactly the right review later.
Talk about it:
  • Which topics felt automatic, and which needed re-deriving from scratch?
  • Did slips or real concept gaps dominate your misses this time?
  • What is one thing you would tell a student starting this term tomorrow?

Mastery looks like: A mixed-topic score of 80% or better under honest conditions, plus a completed error analysis with at least one successful cold re-solve.

Common stumbles: Cramming the night before instead of spaced review across the term; mislabeling a concept gap as "just a slip" to avoid re-studying it.
