Description¶

Question Answering positions questions — not explanations — as the primary driver of a learning episode. Learners must generate an answer from memory, reasoning, or text evidence before receiving confirmation, feedback, or the correct response. The strategy spans oral questioning in class, embedded questions in texts and videos, and quiz-like prompts in adaptive software.

Design Implications¶

Answering questions forces retrieval and elaboration, which strengthens memory far more than rereading the same material — the core of the testing effect (Roediger & Karpicke, 2006). The type of question matters: lower-order recall questions support retention, while "why," "how," and compare/contrast questions drive inference and integration (King, 1994). Questions also function as formative assessment, surfacing misconceptions the instructor can address immediately Assessment for learning improves achievement. [+S].

Context¶

Requirements¶

• Questions calibrated to what learners can plausibly answer from prior instruction or materials
• Wait time after posing a question — several seconds of silence before taking answers
• Feedback or confirmation following learner responses; unanswered questions decay quickly
• A distribution of question types: recall, application, and explanation, not only factual checks

Constraints¶

• Rapid-fire low-level questioning can fragment attention and add extraneous load for novices Cognitive overload degrades learning. [-M]
• Cold-calling without a supportive climate suppresses participation and can threaten belonging Belonging interventions improve outcomes. [~M]
• Questions asked before learners have any relevant knowledge produce guessing, not retrieval — activation of prior knowledge must come first Activation improves learning. [~M]
• Learners frequently ask surface-level questions; without training, self- or peer-questioning stays shallow (Graesser & Person, 1994) [-M]

Implementation Variability¶

• Instructor-posed: whole-class questioning with wait time and cold-call or volunteer response
• Embedded: questions inserted into readings, videos, or simulations at key points
• Peer-generated: learners author questions for each other using question stems ("How are X and Y alike?") (King, 1994)
• System-posed: adaptive quizzing that selects questions based on response history

Target Learners¶

• All levels benefit from retrieval-based questioning; effects are robust across ages and domains (Roediger & Karpicke, 2006) [+S]
• Novices need more scaffolding and lower question difficulty; experts benefit more from transfer-oriented questions [~M]
• Reluctant speakers benefit from think-time, written responses, or small-group answering before public sharing

Target Learning Goals¶

• Retention of factual and conceptual knowledge through retrieval practice
• Comprehension monitoring and inference-making from texts
• Oral academic language and reasoning through explaining answers aloud

Instructions¶

1. Activate relevant prior knowledge before questioning (Activation)
2. Pose the question, then provide 3–5 seconds of wait time
3. Collect responses — individual, think-pair-share, or written (Check-In, Class Discussion)
4. Probe follow-ups: "Why?", "How do you know?", "What if…?" (Coaching)
5. Give immediate corrective or confirming feedback (Assessment)
6. Re-ask the same or parallel questions later in the session or after a delay to exploit spaced retrieval Distributed practice improves retention. [+S]

Related Strategies¶

• Socratic questioning — a sustained dialectical variant where follow-up questions drive the whole exchange
• Cold calling — a distribution technique that raises accountability for answering
• Retrieval practice — the broader family of memory-strengthening techniques that question answering instantiates
• Misconception-aware contrastive remediation videos triggered by incorrect quiz answers

Examples¶

• Recitation in Direct Instruction — high-frequency choral and individual questioning with immediate feedback is a signature feature of Direct Instruction scripts
• Peer question stems (King, 1994) — students use prompt cards ("Explain why…", "What evidence supports…") to question partners during cooperative tasks
• Embedded video questions — platforms like Edpause and Khan Academy interrupt demonstrations with questions the learner must answer before proceeding
