Elaborative Interrogation Prompt Generator
Generate elaborative interrogation prompts that deepen encoding through targeted why and how questions. Use when students memorise without understanding or need deeper processing of content.
What it does
Generates a set of "why?" and "how does this connect?" prompts designed to deepen encoding by forcing students to generate explanations that link new information to existing knowledge. Unlike comprehension questions (which check understanding), elaborative interrogation prompts require students to explain why a fact is true or how it relates to something they already know — the act of generating the explanation strengthens the memory trace. AI is specifically valuable here because effective elaborative prompts must be pitched at the precise intersection of what students are learning and what they already know — too disconnected from prior knowledge and students can't generate explanations; too obvious and there's no elaboration needed.
The evidence behind it
Pressley et al. (1992) demonstrated that answering "why?" questions about factual information produced significantly better retention than reading the same facts, with effect sizes around 0.59. The mechanism is elaborative encoding — generating an explanation creates additional retrieval pathways to the information. Woloshyn et al. (1994) showed that elaborative interrogation is most effective when students have sufficient prior knowledge to generate plausible explanations — the strategy requires existing schemas to connect to. Dunlosky et al. (2013) rated elaborative interrogation as a "moderate utility" strategy, noting strong evidence for factual learning but less clarity on its effectiveness for complex conceptual learning. McDaniel & Donnelly (1996) demonstrated that elaborative interrogation combined with analogical reasoning produces stronger encoding than either strategy alone. Ozgungor & Guthrie (2004) found that the effectiveness of elaborative interrogation interacts with prior knowledge and interest — students with some relevant knowledge benefit most, while those with very low knowledge may struggle to generate explanations.

How to use it in your lesson
For the best results with EvidenceLesson, give it:
- topic — The concept, fact set, or content area students are learning
- student_level — Age/year group and approximate prior knowledge level
- prompt_count — Number of elaborative prompts to generate (recommended 5–8)
- content_text (optional) — The specific text or content students are engaging with
- prior_knowledge (optional) — What students already know that can be connected to this topic
- student_profiles (optional) — From context engine: language levels, prior knowledge data
- learning_objectives (optional) — Specific learning objectives the prompts should support
Known limitations
- Elaborative interrogation requires sufficient prior knowledge to generate explanations. If students have no relevant prior knowledge (e.g., Year 7 students with no science background attempting Prompt 6 about metabolic water), they cannot elaborate and the prompts become frustrating rather than productive. Ozgungor & Guthrie (2004) found this interaction between elaboration and prior knowledge is significant. Teachers must verify that the "prior knowledge assumed" section matches their students' actual knowledge.
- The evidence base is strongest for factual/conceptual learning, not procedural skills. Pressley et al. (1992) and most elaborative interrogation studies used factual materials. The strategy transfers less clearly to mathematical procedures, physical skills, or creative tasks where "why?" questions may not deepen encoding in the same way.
- Elaborative interrogation is more effective than re-reading but less effective than retrieval practice. Dunlosky et al. (2013) rated it as "moderate utility" rather than "high utility." It is best used as a complement to retrieval practice and spaced practice, not as a replacement. Use elaborative prompts during initial encoding, then switch to retrieval practice for consolidation.
