Description¶

When learners must induce rules during practice rather than apply pre-taught rules, the article's Experiment 2 shows varied retrieval practice with corrective feedback is an implementable alternative to worked examples. Students can "be asked to solve varied problems (e.g., 2(x + 3), 4(x + 5), 3(x + 1) and receive feedback that includes the correct answer," then "compare instances, identify common structure, and induce the rule" across problem–feedback cycles.

Design Implications¶

Context¶

Requirements¶

• Practice items must vary while sharing the same underlying rule
• Feedback must display the correct answer after each retrieval attempt

Constraints¶

• Varied retrieval took more learning time than worked examples, and improvement during practice was slower under varied items

Target Learners¶

• novice learners without prior instruction on the target rules, e.g., mathematics students

Target Learning Goals¶

• inducing underlying rules from varied practice instances
• transferring rules to novel problems

Affordances¶

• Exemplar Based Variability Retrieval Account

Claims¶

• Without initial instruction, varied retrieval practice matches varied worked examples and beats repeated retrieval practice for generalization [+M]
• Without initial instruction, repeated worked examples produce better generalization than repeated retrieval practice [~M]
• Feedback likely supported both consolidation and rule induction in the observed retrieval practice benefits [+W]
• Retrieval practice takes more learning time than worked examples, and variability slows improvement during practice [~M]
