Spaced retrieval practice is an active recall technique where intervals of time are increased between subsequent reviews of study material.
Researchers wanted to see how daily spaced retrieval practice using a mobile app affected foreign vocabulary learning. They recruited 80 introductory Spanish language learners who were randomly allocated to either the spaced retrieval app group (Condition 1) or the traditional paper list study group (Condition 2).
At the beginning of the study, all participants in Condition 1 and Condition 2 were given a baseline vocabulary test of 30 Spanish words.
During the next four weeks:
After the four-week period, all participants performed a vocabulary test consisting of the 30 words, and the number of successfully translated words (expressed as a score out of 30) was recorded.
State a fully operationalised directional (one-tailed) experimental hypothesis for this spaced retrieval study.
