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.
q3 i? In two experiments with primary school students learning fraction addition, spaced practice resulted in superior learning to massed practice, with that superiority associated with increased availability of working memory resources measured before the content test. → Ouhao Chen & Fred Paas & John Sweller 2021

q3 · i? · review · r2
Two experiments by Chen et al. (2018) described in the review: primary school students learned fraction addition in massed (1 day) or spaced (3 days) practice, with a working memory capacity test administered immediately before the content test. The review reports "spaced practice resulted in superior learning to massed practice with that superiority associated with increased availability of working memory resources."
"The results showed that spaced practice resulted in superior learning to massed practice with that superiority associated with increased availability of working memory resources."
