Phase 1: Prepare
Step 1 Warm-up recall
From M8.L1: why write the test before studying?
Private: nothing you type here is sent or stored.
Step 2 Learning goal
By the end of this lesson you can:
- keep a session log (Foundation);
- score a test as a percentage (Core);
- compute a difference in points (Core).
Phase 2: Teach
Step 3 A familiar example
A scientist who does not write down the readings cannot report them honestly later. A study log does the same job.
Step 4 Clear explanation
Run the plan as written and record each session: date, topic, method, minutes and anything that went wrong. If a session is missed, note it; do not quietly drop it. After the delay, take the test closed-book, mark it against your answer key and record the scores.
| Topic (invented) | Method | Questions | Correct | Score |
|---|---|---|---|---|
| A | Retrieval | 10 | 8 | 80% |
| B | Rereading | 10 | 6 | 60% |
| Difference | 20 points |
Check the working: 8 / 10 = 80% and 6 / 10 = 60%; the difference is 80 − 60 = 20 points. Note that with only 10 questions, each question is worth 10 points, so a 20-point gap is 2 questions. Report the raw counts as well as the percentages, so readers can see how small the numbers are.
Mark honestly: give credit only for answers that match the key, and have a friend mark them if you can. Keep the results table next to the log. See retrieval practice for why the closed-book test is itself a learning event.
Step 5 Worked example (4 marks)
Retrieval scored 9 of 12 and rereading 6 of 12 on a delayed test. Give both percentages and the difference.
- Retrieval: 9 / 12 = 0.75, so 75%. (1 mark)
- Rereading: 6 / 12 = 0.5, so 50%. (1 mark)
- Difference: 75 − 50 = 25 points. (1 mark)
- Answer: 75%, 50% and 25 points. (1 mark)
Phase 3: Practise
Step 6 Learner practice (instant-marked)
1. A session log should record:
So you can check what happened.
2. 8 correct out of 10 is:
8 / 10.
3. 80% and 60% differ by:
80 − 60.
4. With 10 questions, one question is worth:
100 / 10.
Phase 4: Close
Step 7 Recap
- Log every session, including misses.
- Score the delayed closed-book test against a key written earlier.
- Report raw counts and percentages, and the difference in points.
Step 8 Exit ticket (ungraded)
7 of 10 and 4 of 10: percentages and difference?
Private: nothing you type here is sent or stored.
Step 9 Go further (Extension)
Run a small version with two short topics and record the results.
Common mistakes
| Mistake | Why it fails |
|---|---|
| Dropping a bad session from the log | Record it. |
| Reporting only percentages | Give the counts too. |
| Marking generously | Stick to the key. |
Limits. Ten questions give a coarse score; one question changes the result by 10 points.
