fullTitle: "Transfer of test-enhanced learning: Meta-analytic review and synthesis."
authors: ["Steven C. Pan","Timothy C. Rickard"]
Meta-analytic review of the empirical literature around Retrieval practice and transfer learning. Includes studies which perform the classic three-phase retrieval practice protocol (initial study, practice test, final recall test).
The analysis examines many different types of possible transfer:
Grand weighted mean effect size for transfer of test-enhanced learning: d = {0.4} ☉
They find a medium-large effect (d=0.58) for transfer across initial and final test formats.
The authors coded a number of candidate moderators for transfer effects.
Response congruency (i.e. practice and final tests having substantially overlapping answers) was the most substantive: “When there was no response congruency between the initial and final tests, the weighted effect size was d = 0.28…; if response congruency held, the estimated effect size increased by d = 0.30… yielding an estimated effect size of d = 0.58.”
They also find that a higher initial accuracy was associated with greater likelihood of transfer. (increased d by 0.0058 for each 1pp in initial test).
The last significant moderator they found was the presence of elaborated retrieval practice, which accounts for a d=0.23 boost. Here elaborated retrieval practice refers either to broad encoding methods (subjects instructed to think of all related information, to construct a detailed explanation, multiple questions involving higher-order Bloom’s taxonomy levels, etc) or to post retrieval processing of elaborative feedback.
This figure summarizes the three effects combined:

And this one describes the effect of initial test performance alone in more detail. It’s interesting that the transfer effect disappears completely for particularly poor performance:

It’s interesting to note that response congruency may take many forms, in terms of mechanistic retrieval pathways:

In general, transfer effects are less potent than the corresponding direct Testing effect—which makes sense.

Q. Three substantive moderating factors?
A. Initial accuracy, response congruency, and elaborated retrieval practice. ☉
Q. What two categories of design properties are included in the category of “elaborated retrieval practice”?
A. Broad encoding methods, post-processing of elaborative feedback ☉
Q. What’s meant by “broad encoding methods”?
A. Explicit instruction to think of all possibly relevant information, constructing a detailed explanation of one’s response, multiple tasks about the same detail including multiple levels of Bloom’s taxonomy, etc ☉
