Covering the Book or Teaching the Standard: A Six-Week Electricity Unit
Rana teaches physics at a girls' school in Zarqa. Her Grade 9 electricity unit must be finished in six weeks: four 45-minute periods a week, so 24 periods. The textbook prints nine sections and the teacher guide suggests two periods per section. Three lab sessions are scheduled, because the lab is shared among twelve teachers and holds only six working multimeters for classes of 38. The school-wide end-of-unit test in week 6 is drawn from the national standards and is mostly application items, including circuit reasoning and calculation. On a pre-test, 28 of 38 students described a series circuit correctly in words, but only 6 could predict what happens to bulb brightness when a second bulb is added in series, and 31 wrote that current 'gets used up'. Rana feels pressure to 'cover the book' because a parent complained last term that her daughter's class was behind. Two periods will be lost to a school activity.
1. Rana has 22 usable periods. Showing your arithmetic, decide what to keep, cut, combine and reorder, and justify the decisions against the standards and the pre-test data.

Arithmetic. 6 weeks × 4 periods = 24. Minus 2 for the school activity = 22. Minus 1 for the end-of-unit test = 21 teaching periods. The textbook plan needs 9 × 2 = 18 periods plus 3 labs = 21, which leaves zero periods for retrieval, formative checking, feedback or slippage.
A workable allocation (21 periods).
- 6 lesson sequences × 2 periods = 12, each built around one standard and its application item type
- 3 lab periods
- 3 retrieval-practice periods (short, spaced review of the previous sequence)
- 2 formative checkpoints with feedback
- 1 buffer
What to keep. Anything the standards make application-level and anything that hits the documented misconception: current 'used up', and brightness/resistance reasoning. That misconception is the highest-leverage target, since 31 of 38 students hold it and the test is application-heavy.
What to cut or combine. Sections that repeat the same idea at greater vocabulary depth, and decorative historical or biographical material that is not assessed. Merge the three sections on resistance, Ohm's law and series/parallel into one 2-period sequence with a single model, so students meet one representation repeatedly rather than three superficially.
What to reorder. Start with the qualitative circuit-reasoning sequence and the first lab in week 1, because the pre-test shows the verbal definition is already secure and the reasoning is not. Calculation comes after the qualitative model is stable, not before. This is backward design from the test standards, not book order.
2. Adapt the three laboratory slots to six multimeters, 38 students and a shared lab. Describe the structure of a practical lesson and how you would know it worked.

Structure. Split the class into six groups of six and run four stations rotating every 8 minutes inside a single 45-minute period:
- Build station - cells, bulbs, wire; students construct series and parallel circuits from a card and predict brightness before switching on.
- Measure station - the six multimeters, one per group, with a recording sheet limited to two readings so the queue moves.
- Prediction–test station - add a second bulb in series; students commit to a written prediction, then test.
- Model station - draw the circuit and write one sentence explaining the result, then compare with the prediction.
Roles rotate each station: builder, measurer, recorder, reporter, timekeeper, checker. Pre-lab in the previous period: safety, how to read the meter, and a written prediction so students arrive with a hypothesis rather than a worksheet.
Whole-class data board afterwards: each group posts one result, and the class confronts the 'current is used up' idea with the pooled evidence.
Evidence it worked: (a) the proportion of correct predictions on the brightness item rises from 6/38 on the pre-test to at least 25/38 on the post-probe; (b) every group's recording sheet is complete and legible; (c) in the following lesson, students can explain the result in writing using the words 'current' and 'resistance' correctly. If predictions do not move, the station task was probably too crowded and needs simplifying rather than repeating.
3. The complaining parent says the class is 'behind the book'. Write the substance of Rana's reply, and state what she should not concede.

Substance of the reply. Acknowledge the concern without accepting its premise: the class is following the national standards, and the sequence has been reorganised so that the assessed application skills are taught earlier and practised more, not skipped. Offer concrete evidence: the pre-test and post-probe results, the unit plan with dates, and the sample of student work from the lab. Invite the parent to see the plan and to ask about a specific standard rather than about page numbers.
What not to concede. Do not promise to teach every textbook page in order, and do not apologise for using lab time for reasoning. Do not present coverage as the measure of learning, because that would contradict what the assessment is designed to test and would push the class back toward the plan that leaves no time for feedback. Do not discuss other students or compare classes.
The underlying judgement. 'Behind' is only meaningful against a specified standard. Rana's professional obligation is to the standards and the students' misconceptions, and her evidence should be the proportion of students who can reason about a circuit - 6 of 38 at the start - not the page reached on a given date. She should also flag honestly that if the school insists on full textbook coverage, something must be dropped, and ask the head of department to decide in writing which.
