Subclaims¶

q2 i? Sleep and consolidation processes play a significant role in semantic memory development, and given that most adolescents do not get sufficient sleep on school nights partly due to early school start times, delaying start times may benefit memory formation. → Fandakova 2016

Evidence¶

Fandakova 2016¶

Fandakova, Yana; Bunge, Silvia A. (2016). What Connections Can We Draw Between Research on Long-Term Memory and Student Learning? Mind, Brain and Education, 10(3). https://doi.org/10.1111/mbe.12123

q2 · i? · review · r2

Review-based claim from the Shing and Brod article as summarized here. The introduction notes accumulating evidence that most adolescents do not get sufficient sleep on school nights, in part due to early school start times, and suggests delaying start times may benefit memory formation and new semantic knowledge acquisition.

"Shing and Brod also highlight the significant role of sleep and consolidation processes for semantic memory development."

Discussion¶

Learner Variables¶

• Long-Term Memory — outcome: instruction changes it
• Sleep — predictor: learners who differ on it differ in outcomes
