Deaf learners frequently demonstrate significantly less vocabulary knowledge than hearing age-mates. Studies involving other domains of knowledge, and perhaps deaf learners' academic performance, indicate similar lags with regard to world knowledge. Such gaps often are attributed to limitations on deaf children's incidental learning by…

Four experiments, each building on the results of the previous ones, explored the effects of several manipulations on learning and the accuracy of metacognitive judgments among deaf and hard-of-hearing (DHH) students. Experiment 1 examined learning and metacognitive accuracy from classroom lectures with or without prior "scaffolding" in the form…

Four experiments investigated classroom learning by deaf college students receiving lectures from instructors signing for themselves or using interpreters. Deaf students' prior content knowledge, scores on postlecture assessments of content learning, and gain scores were compared to those of hearing classmates. Consistent with prior research, deaf…

Four experiments examined the utility of real-time text in supporting deaf students' learning from lectures in postsecondary (Experiments 1 and 2) and secondary classrooms (Experiments 3 and 4). Experiment 1 compared the effects on learning of sign language interpreting, real-time text (C-Print), and both. Real-time text alone led to significantly…

Despite the importance of sign language interpreting for many deaf students, there is surprisingly little research concerning its effectiveness in the classroom. The limited research in this area is reviewed, and a new study is presented that included 23 interpreters, 105 deaf students, and 22 hearing students. Students saw two interpreted…
