Research has shown that fraction magnitude and whole number division are important precursors to learning and understanding fractions. Deaf and hard-of-hearing (DHH) students are consistently challenged with learning fractions from K-12 through college. Sixty DHH college students were tested for both their understanding of magnitude between two…

This study assessed knowledge of numerically quantified English sentences in two learner populations--second language (L2) learners and deaf learners--whose acquisition of English occurs under conditions of restricted access to the target language input. Under the experimental test conditions, interlanguage parallels were predicted to arise from…

Deaf Learners' Acquisition of fundamental lexical properties of high-frequency English verbs related to transitivity and intransitivity was examined, including the subtle distinction between unergative and unaccusative verbs. A 140-item sentence acceptability rating scale was used to assess this lexical knowledge in deaf college students at two…

This research contrasted deaf and hearing students' interpretive knowledge of English sentences containing numeral quantifier phrases and indefinite noun phrases. A multiple-interpretation picture task methodology was used to assess 305 participants' judgments of the compatibility of sentence meanings with depicted discourse contexts.…

Research tells us that academic preparation is key to deaf students' success at college. Yet, that is not the whole story. Many academically prepared students drop out during their first year. This study identified entering deaf college students' personal factors as assessed by their individual responses to both the "Noel-Levitz College…

This study explored the efficacy of visual input enhancement, specifically "essay enhancement", for facilitating deaf college students' improvement in English grammatical knowledge. Results documented students' significant improvement immediately after a 10-week instructional intervention, a replication of recent research. Additionally, the…

English sentences containing the universal quantifiers "each", "every", and "all" are highly complex structures in view of the subtleties of their scope properties and resulting ambiguities. This study explored the acquisition of universal quantifier sentences as reflected in the performance of three diverse college-level student groups on a…

In one investigation with 48 deaf and hard-of-hearing (hh) high school students and a second investigation with 48 deaf/hh college students, all viewed one lecture with an interpreter and one with the C-Print[R] speech-to-text support service. High school students retained more lecture information when they viewed speech-to-text support, compared…

Focus-on-form English teaching methods are designed to facilitate second-language learners' noticing of target language input, where "noticing" is an acquisitional prerequisite for the comprehension, processing, and eventual integration of new grammatical knowledge. While primarily designed for teaching hearing second-language learners, many…

This study of deaf college students examined specific relationships between their mathematics performance and their assessed skills in reading, language, and English morphology. Simple regression analyses showed that deaf college students' language proficiency scores, reading grade level, and morphological knowledge regarding word segmentation and…

Deaf and hearing students' knowledge of English sentences containing universal quantifiers was compared through their performance on a 50-item, multiple-picture task that required students to decide whether each of five pictures represented a possible meaning of a target sentence. The task assessed fundamental knowledge of quantifier sentences,…

This research examined the use of visual-spatial representation by deaf and hearing students while solving mathematical problems. The connection between spatial skills and success in mathematics performance has long been established in the literature. This study examined the distinction between visual-spatial "schematic" representations that…

Deaf children's thought processes are analyzed in regard to J. Piaget's theory of cognitive development. (Author)

This study examined the ability of 70 deaf and 58 hearing students at the college and middle school levels to discern and apply knowledge of printed word morphology, especially morpheme segmentation and semantic analysis. Deaf college students scored similarly to middle school hearing students. (Contains references.) (Author/DB)

The generally bleak achievement scores of deaf children are contrasted with the near normal reports of both IQ and conceptual development. (Author)
