Retrieval Practice Question Generator
Generate retrieval practice questions at varied difficulty levels for a topic or concept. Use when creating quiz starters, revision activities, or low-stakes testing materials.
What it does
Generates a set of retrieval practice questions that force genuine reconstruction of knowledge from memory — not recognition, not re-reading, not familiarity-based guessing. The skill distinguishes between free recall (no cues), cued recall (partial cues), and recognition (select from options) question types, and calibrates the mix based on student level and time since learning. AI is specifically valuable here because designing questions that target reconstruction rather than recognition requires deep understanding of the testing effect literature — most teacher-made quiz questions inadvertently test recognition.
The evidence behind it
The testing effect is one of the most robust findings in cognitive psychology. Karpicke & Roediger (2008) demonstrated that retrieval practice produces substantially better long-term retention than re-studying, even when re-study involves more total exposure time. Roediger & Butler (2011) established that retrieval practice strengthens memory traces through a distinct mechanism from encoding — the act of reconstruction itself modifies the memory. Rowland's (2014) meta-analysis of 159 studies found a mean effect size of 0.50 for testing versus restudy, with effects robust across age groups, materials, and delay intervals. Critically, Agarwal et al. (2012) replicated these effects in real classroom settings with middle school students, confirming the lab-to-classroom transfer. Dunlosky et al. (2013) rated practice testing as one of only two "high utility" learning strategies in their landmark review of ten techniques.

How to use it in your lesson
For the best results with EvidenceLesson, give it:
- topic — The specific concept or skill students need to retrieve
- student_level — Age/year group and approximate prior knowledge level
- question_count — Number of questions to generate (recommended 6–10)
- student_profiles (optional) — From context engine: individual language levels, prior knowledge gaps
- competency_framework (optional) — From context engine: school's assessment framework or curriculum standard
- time_since_learning (optional) — How long ago students first encountered this material
- known_misconceptions (optional) — Specific misconceptions already observed in this cohort
Known limitations
- Cannot verify factual accuracy against a specific textbook or syllabus. The questions are generated from general subject knowledge. Teachers should check that terminology and expected answers match what was actually taught — especially for Q2 and Q4 where specific terms may vary between curricula.
- Free recall questions may overwhelm students with very low prior knowledge or limited English proficiency. For EAL students or those with significant gaps, increase the proportion of cued recall and recognition questions. Chain with the Scaffolded Task Modifier for language-adapted versions.
- The spacing recommendation is calibrated to lab research on optimal intervals. Real classroom scheduling constraints (timetable gaps, holidays, assessment windows) may make the recommended spacing impractical. Teacher judgment on timing is always necessary.
