Subclaims¶

q2 i? Learners who studied L2 vocabulary under a harder-to-learn condition showed more enhanced long-term retention than those who learned under an easier-to-learn condition. → Joshua Wedlock & Christopher Binnie 2025

The article reports, citing Schneider et al. (2002), a vocabulary learning study in which participants under a "harder-to-learn" condition "experienced more enhanced long-term retention in comparison to those who learned under an “easier-to-learn” condition." No effect size is printed.

Learner Variables¶

• Long-Term Memory — outcome: instruction changes it

Related Claims¶

• Deeper processing of target language improves lexical retention and long-term learning — a narrower finding that bears on this claim
• Retrieval practice and spaced retrieval improve achievement and retention by medium amounts, while interleaving helps category learning only for some materials and blocking beats it for words — related
• Retrieval practice improves long-term retention — related
• Faster rate of learning may be negatively related to long-term retention (efficiency-effectiveness trade-off) — possibly the same claim (merge candidate)
• Spaced Practice Improves Retention — related
• The GoldList Notebook Method increases long-term retention of L2 idioms compared with a vocabulary lesson alone — related
• Generation as the sole desirable difficulty produced no detrimental effect on L2 vocabulary recall, in contrast to prior short-term findings — a narrower finding that bears on this claim
• Struggling to encode, retrieve, and reorganize information produces deeper comprehension and retention, and AI-supplied ready-made solutions short-circuit these processes — a narrower finding that bears on this claim
• Problem isomorphs with identical structure differ greatly in difficulty; Monster Change took 16 times as long to solve as the standard problem — related
