Discussion¶

Learner Variables¶

• Long-Term Memory — outcome: instruction changes it
• Vocabulary — outcome: instruction changes it

Related Claims¶

• Task-essentialness and productive use of new words in goal-directed activity may positively affect vocabulary learning and retention — possibly the same claim (merge candidate)
• Desirable difficulty: harder-to-learn conditions yield enhanced long-term retention — a broader claim this one bears on
• Learners invest more effort in tasks they perceive as interesting, personally important, or useful to their future goals. — related
• Grades themselves, regardless of formula, detrimentally affect creative thinking, long-term retention, interest in learning, and preference for challenging tasks — related
• 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
• Vocabulary knowledge gained from eight encounters persisted over two weeks, with no significant immediate-to-delayed test differences — related
