Study Summary
This study is designed to advance the promising yet underutilized research on retrieval practice by evaluating the effectiveness and efficiency of two key retrieval practice features (feedback and spacing). The study uses four single case adapted alternating treatments studies, each with 5- to 9-year-old children who are deaf and hard of hearing to evaluate the effects of feedback and spacing on the efficiency of word learning and retention.
Primary Outcome
Count of participants for whom the intervention is successful based on percent accuracy labeling target words expressively (number of target words correctly labeled when shown the object divided by the number of words in the set \[i.e., 4\] times 100). The count of participants indicates the number of participants who exhibited a functional relation indicating greater performance for at least one active intervention condition versus the control condition within the comparison phase.
Interventions
- BEHAVIORAL Feedback with massed trials
- BEHAVIORAL Feedback with spaced trials
- BEHAVIORAL No feedback with massed trials
