The Effect of Prequestions on Learning: A Multilevel Meta-Analysis
The reviewed source can support a conservative practical protocol.
Brali decision: Protocol candidate. This page summarizes a reviewed evidence boundary; it does not reproduce the source and it does not turn one paper into a universal prescription.
What the source supports
Prequestions can improve later learning of the specific information they target. The meta-analysis reported g = 0.66 for prequestioned information and g = 0.01 for non-prequestioned information; feedback alongside prequestions was associated with stronger targeted learning.
What it does not establish
Prequestions improve learning of the entire lesson.
Any question asked before learning will be beneficial.
There is one evidence-backed optimal number of prequestions.
A wrong first answer is itself sufficient without later exposure or correction.
Prequestions replace retrieval practice, practice problems, or feedback after learning.
Important limitations
The average benefit is specific to prequestioned information rather than a broad benefit to all content.
The meta-analysis does not establish one universal question count, timing rule, or content format.
Effect sizes summarize heterogeneous studies and do not guarantee the same result for an individual learning session.
Design: Multilevel meta-analysis of the prequestion literature examining learning of prequestioned and non-prequestioned content across variations in learning event, participant sample, and assessment conditions.
Population: Learners represented across the studies included in the meta-analysis; the practical protocol is intentionally population-neutral and does not convert subgroup findings into a universal dose.
Exposure / intervention: Questions attempted before an educational activity, compared with conditions without those prequestions; some study conditions also provided feedback.
Outcomes: Learning of prequestioned information; Learning of non-prequestioned information
This evidence decision is attached to the maintained Brali entry above. The public protocol may be narrowed, reviewed, or kept practical according to the decision.
Editorial note: Editorial action: publish a new Skill Sprint protocol because no prequestion/pretesting surface was found in the canonical index or override layer. Make the target-versus-nontarget boundary prominent.
Use the boundary, not just the headline
When an AI agent or a person retrieves this decision, preserve both the supported claim and the unsupported or overstated claims. Dropping the boundary would turn a reviewed source into a stronger claim than Brali actually maintains.
