Description

The chapter's organizing framework: learners study materials, a retrieval practice condition completes initial retrieval activities while a control does not, and all take a final criterial assessment. The factors explored include "aspects of the initial retrieval practice conditions, the conditions of the final criterial assessment, characteristics of the learners, the nature of the materials, and the setting of the study", which structure the chapter's sections.

Design Implications

Context

Requirements

• A control condition, such as no additional activity, extra restudy, or an elaborative study activity.
• A final criterial assessment, given anywhere from a few minutes to several months after initial activities.

Constraints

• The chapter notes comparisons with restudy are biased toward restudy because retrieval conditions rarely reexpose all material.

Target Learners

• Researchers studying retrieval-based learning

Target Learning Objectives

• Design and interpret retrieval practice studies across initial conditions, final assessments, learners, materials, and settings

Claims

• Retrieval Practice Outperforms Repeated Study Rowland Meta Analysis [+S]
• Quizzing outperforms no/filler activity, fewer-question testing and restudying, with a larger advantage over no/filler activity (low reexposure) than over restudying (high reexposure); against other elaborative strategies its advantage is small and not significant. [~W]
• The effect of retrieval practice format on reading comprehension does not differ significantly between an immediate and a three-week-delayed final test [+W]
• Map drawing after 30 min is more accurate for maps learned through covert-retrieval tests than for maps learned through equal conventional study time [+W] — attached 2026-10-16 from Shana K. Carpenter et al. (2007), which proposed "Covert retrieval with self-scoring as a method for extending the testing effect to nonverbal, visuospatial materials"; tests this page's relationship.
• Students in the inserted-question condition spend more time reading the text initially than students in the post-reading condition [~W]
• Practice retrieval performance did not differ significantly between the three retrieval strategy conditions [~W]
• Final recall does not differ reliably between participant-controlled and computer-controlled feedback skipping [~W]
• Quiz accuracy declines from immediate to 1-week delayed testing regardless of text medium [+W]
• Information retrieval questions were consistently easier than comprehension questions across both visualisation formats [~W]
• The retrieval (TTST) advantage appeared at both short (5 min) and long (24 h) retention delays, with no reliable evidence that it differed between them [+W]
• Testing effects are stronger when practice and final test formats are identical (g = 0.63) than dissimilar (g = 0.53), supporting transfer-appropriate processing [+W]
• A systematic review of 50 classroom experiments found retrieval practice yields medium-to-large benefits in most cases, but only 6% were conducted in non-WEIRD countries [~W]
• In Study 1, the three conditions did not differ significantly on the immediate post-test of conceptual knowledge [~W]
• Taking an immediate plus delayed final test yields higher delayed test performance with less invested effort than taking only a delayed test (Experiment 2) [+W]
• Higher-level quiz questions engage learners in generative activities as well as retrieval [~W]
• When learners receive initial instruction, retrieval practice yields better generalization than worked examples regardless of item variability [~W]
• Posttests were coded as delayed if they occurred at least one day after treatment, with two-delay studies and studies lacking day/week delay metrics excluded from mean and median delay calculations [~W]
• Practice gains are greater for nonsense material (average final gain 28%) than for sense-material (average final gain 10%). [~W]
