What This Skill Does
This skill generates evidence-based checking-for-understanding protocols that move beyond superficial "Does everyone understand?" toward diagnostic assessment. Rather than merely confirming student attention, it produces actionable techniques paired with decision trees specifying how to respond based on results.
The tool addresses a fundamental gap in classroom practice: most CFU consists of optional hand-raising, which checks only volunteering students while leaving the majority's understanding unmeasured. This skill instead designs protocols ensuring ALL students respond, using mini-whiteboards, finger votes, cold calling with thinking time, and targeted hinge questions—each matched to specific lesson moments.
Evidence Foundation
- Rosenshine (2012) emphasized that "successful teachers ask a large number of questions, check the responses of all students" through systematic feedback—not ad hoc questioning.
- Black & Wiliam (1998) demonstrated formative assessment produces approximately 0.66 effect size when teachers act on results, establishing that assessment without response is inert.
- Wiliam (2011) operationalized formative assessment into five strategies, emphasizing engineering "activities and learning tasks that elicit evidence of learning" as the critical design step.
- Lemov (2015) provided classroom-ready techniques: cold calling, standardised response formats, and show calls.
- Christodoulou (2017) advanced hinge questions—single diagnostic items where each distractor maps to a specific misconception.
Input Requirements
Required:
- Lesson content (what is being taught)
- Lesson stage (during instruction, after practice, end of lesson, or all stages)
- Student level (year group and class characteristics)
Optional: class size, known misconceptions, student profiles, available resources
Output Structure
- During-Instruction Checks – 2–3 quick, whole-class checks with specific questions and technique notes
- Hinge Question – A diagnostic multiple-choice item with distractor analysis
- Cold-Call Sequence – Scripted questions with built-in thinking time (10–15 seconds before naming the student)
- Exit Ticket – A 5-minute task diagnosing readiness for subsequent instruction
- Response Decision Tree – Clear pathways: proceed if 80%+ correct; address specific misconceptions if 50–80% correct; reteach if below 50%
Known Limitations
- CFU measures momentary understanding, not retention. Must pair with spaced retrieval practice for durability.
- Mini-whiteboards invite copying and strategic timing; cold calling individuals provides unambiguous data but only for one student per question.
- Real-time judgment remains essential.
