The proposed research addresses a long-standing and important challenge of improving language skills of children who are deaf and hard of hearing, a historically under researched group. The study aims to leverage retrieval practice - an empirically validated intervention approach - for improving how efficiently children who are deaf and hard of hearing learn and retain new words. To advance the promising yet underutilized research on retrieval practice, the study completes the next logical step of evaluating the effectiveness and efficiency of two key retrieval practice features: feedback and spacing. Feedback is predicted to result in more efficient learning because it focuses attention on unmastered material, prevents the illusion of success, and reduces repeated errors. Spacing trials are predicted to result in more efficient learning than massed trials because they require more effort with fewer cues provided. The study will accomplish these aims through four single case adapted alternating treatments design studies with sixteen 5- to 8- year-old children who are deaf and hard of hearing. Study innovations include the critical evaluation of retention and use of a multi-session intervention context. The knowledge gained will guide language intervention for children who are deaf and hard of hearing.
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 four 5- to 8-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.
