Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? The chapter reports, citing Larsen et al. (2013), that initial testing of clinical neurology topics enhanced medical students' retention 6 months later relative to studying a review sheet. → Karpicke 2017
q2 i? The chapter reports, citing Carpenter et al. (2009), that retrieval practice of history facts enhanced middle-school students' retention relative to repeated study on a test 9 months later. → Karpicke 2017 (2)

q2 · i? · review · r3
The chapter reports, citing Larsen et al. (2013), research with medical students in which "initial testing of clinical neurology topics enhanced retention 6 months later", relative to a review sheet. No effect size is printed.
"For example, in research with medical students, Larsen et al. (2013) found that initial testing of clinical neurology topics enhanced retention 6 months later, relative to initially studying a review sheet."

q2 · i? · review · r3
The chapter reports, citing Carpenter et al. (2009), research with middle-school students where "initial retrieval practice of history facts enhanced retention relative to repeated study" on a final test 9 months later.
"In research with middle-school students, Carpenter et al. (2009) found that initial retrieval practice of history facts enhanced retention relative to repeated study on a final test given 9 months after the initial learning session."
Discussion¶
Related Claims¶
- Retention interval moderates the testing effect: effects are larger after a day or more than at shorter intervals, where individual studies vary from reliable to null or reversed — the general claim this finding bears on, with the studies behind it
- Retrieval Practice Enhances Long Term Retention
- Classroom quizzing delivered by clickers, computer software, or paper improves student performance on classroom exams in middle school and college courses — related
- Most middle and high school students surveyed after classroom retrieval practice programs viewed them positively and said frequent retrieval practice helped them feel less nervous about exams — related
- Test-enhanced learning generalizes across education levels, from elementary school (g = 0.328) through university/college (g = 0.486). — related
- In the author's cited longitudinal classroom experiments, lessons with retrieval practice raised course grades from a C to an A level, and three spaced retrieval opportunities were optimal even nine months later — related
- Retrieval practice has been implemented and studied in authentic middle school classrooms, with general recommendations for applied research — related
