Teacher pack · Debugging in Exam Questions

Marking scheme

Band	Marks	Descriptor
Mastered	46–54	Applies debugging in exam questions fluently, including in unfamiliar contexts, with clear justification.
Secure	35–45	Reliable in routine questions; reasoning is mostly complete.
Developing	22–34	Secure in scaffolded items, inconsistent once support is removed.
Emerging	0–21	Needs re-teaching of the core rule before progressing.

Teacher notes

Set the warm-up as a five-minute starter; it diagnoses readiness for debugging in exam questions before you teach.
Guided practice is the pivot point — circulate here rather than during independent practice.
Mark the reasoning questions with the marking scheme bands, not raw totals, so progress is comparable across variants.
Students who band Emerging should repeat the Easy variant of this same subtopic before moving on within Debugging.

Common student mistakes

Confusing debugging in exam questions with a neighbouring idea in debugging.

Teaching tips

Model one worked example of debugging in exam questions under a visualiser before handing the sheet out.
Ask students to predict which question they will find hardest, then check the prediction afterwards.
Pair Developing students with Secure students for the guided practice block only.
Use the answer key as a self-marking station rather than collecting the sheets in.

Extension activities

Challenge worksheet on debugging in exam questions with justification-only questions.
Design your own debugging in exam questions question and write the mark scheme for it.
Link debugging in exam questions to the next subtopic in Debugging and explain the connection.
Ten-minute timed practice to convert accuracy into fluency.
