Unsuccessful retrieval attempts can enhance subsequent encoding and learning. In three experiments, subjects either attempted to retrieve word pairs prior to studying them (e.g., attempting to recall tide-? before studying tide-beach) or did not attempt retrieval and retention of the studied targets was assessed on a subsequent cued recall test. Experiment 1 showed that attempting retrieval enhanced subsequent encoding and recall relative to not attempting retrieval when the word pairs were semantically related, but not when the pairs were unrelated. In Experiment 2, studying a different word pair prior to the correct pair (e.g., studying tide-wave prior to tide-beach) did not produce the same effect as attempting retrieval prior to studying. Constraining retrieval to a particular candidate word prior to study (e.g., recalling tide-wa__ before studying tide-beach) produced a negative effect on subsequent recall. Experiment 3 showed that attempting retrieval did not enhance encoding when a brief delay occurred between the retrieval attempt and the subsequent study trial. The results support the idea that a search set of candidates related to the retrieval cue is activated during retrieval and that this retrieval-specific activation can enhance subsequent encoding of those candidates.

Memory researchers using paired associates have benefited greatly from the Swahili-English norms reported by Nelson and Dunlosky (1994). Given recent increases in the amount and kinds of research using paired associates, however, researchers would now benefit from an expanded set of normative measures for foreign language vocabulary words. We report data for 120 Lithuanian-English word pairs collected from 236 undergraduates. Participants completed three study-test trials and were asked to make metacognitive judgments for each item. We report normative recall performance, recall latencies, and error types for each item across trials, as well as the perceived difficulty of each item on the basis of metacognitive judgments.

Open Educational Resources (OER) have been lauded for their ability to reduce student costs and improve equity in higher education. Research examining whether OER provides learning benefits have produced mixed results, with most studies showing null effects. We argue that the common methods used to examine OER efficacy are unlikely to detect positive effects based on predictions of the access hypothesis. The access hypothesis states that OER benefits learning by providing access to critical course materials, and therefore predicts that OER should only benefit students who would not otherwise have access to the materials. Through the use of simulation analysis, we demonstrate that even if there is a learning benefit of OER, standard research methods are unlikely to detect it.

Retrieval practice is a powerful way to promote long-term retention and meaningful learning. However, students do not frequently practice retrieval on their own, and when they do, they have difficulty evaluating the correctness of their responses and making effective study choices. To address these problems, we have developed a guided retrieval practice program that uses an automated scoring algorithm, called QuickScore, to evaluate responses during retrieval practice and make study choices based on student performance. In Experiments lA and IB, students learned human anatomy materials in either repeated retrieval or repeated study conditions. Repeated retrieval in the computer-based program produced large gains in retention on a delayed test. In Experiment 2, we examined the accuracy of QuickScore's scoring relative to students' self-scoring of their own responses. Students exhibited a dramatic bias to give partial or full credit to completely incorrect responses, while QuickScore was far less likely to score incorrect responses as correct. These results support the efficacy of computer guided retrieval practice for promoting long-term learning.
