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 Butler et al. (2006), that more alternatives benefit subsequent retention when initial retrieval success is high. → Karpicke 2017 q2 i? The chapter reports that when initial retrieval success is low, more alternatives hurt learning because selected incorrect responses are remembered. → Karpicke 2017 (2)

The chapter reports, citing Butler et al. (2006), that "When the level of initial retrieval success is high, having more alternatives bene fits subsequent retention", presumably by making retrieval more effortful.

"When the level of initial retrieval success is high, having more alternatives bene fits subsequent retention."

The chapter reports the other half of this pattern: "when initial retrieval success is low, having more alternatives hurts learning", as students select and later remember incorrect responses.

"However, when initial retrieval success is low, having more alternatives hurts learning. In this case, students are more likely to select incorrect responses on the initial test, and those incorrect responses are remembered on future tests."
