Argues that no single approach is satisfactory for teaching all grammatical rules in English-as-a-Second-Language instruction, and that rules must first be distinguished on the basis of certain linguistic criteria before pedagogical strategies can be considered. (17 references) (Author/CK)

A study of 141 children (ages 4-5) with language impairments and a study of 120 children (ages 7-12) with oral language and/or reading problems, indicate a relationship between the processing of phonological and semantactic linguistic information and performance on oral language and reading tests three years later. (Author/CR)

The compositions of 49 students (ages 10-14) with deafness or hearing impairments and 49 typical students were compared to investigate the frequency and proportional distribution of written-language variables. Differences were found between the strategies chosen by the students with deafness or hearing impairments in both syntax and semantics and…

A study examined how 44 bilingual (Spanish-English) children (ages 4-7) used taxonomic versus slot-filler strategies in a category-generation task presented in both languages. Younger bilingual children generated approximately equal numbers of items in both conditions, however, older bilingual children were beginning to demonstrate a taxonomic…

Input language addressed to language-learning children was analyzed to assess the quality of the semantic-syntactic correspondence posited by the semantic bootstrapping hypothesis. This correspondence was strong--objects were labeled with nouns, actions with verbs, attributes with adjectives--and may serve to make children's construction of…

Describes the use of language analysis and speech-act categories (declarations, assertives, directives, commissives, and expressives) to deal with meaningful classroom concerns, thereby enabling the teacher and students to work more effectively together. (KEH)

Fourteen specifically language-impaired children, age four to seven, pointed to pictures in, and acted out, semantically reversible sentences that varied in thematic content and in the order of thematic roles. Compared to children matched on language age and chronological age, subjects' comprehension was significantly lower. (Author/JDD)

Concepts, categories, time allotment, and instructional techniques associated with teaching Science/Technology/Society issues were examined for 65 exemplary secondary level science teachers. An analysis of a Science Teaching Issue Opinionnaire and another questionnaire are presented. Thirty-two references are listed. (CW)

Encourages classroom teachers to improve their students' reading and reasoning skills by helping them to interpret math problems correctly. (RAE)

Examination of a two-year-old's early determiner-noun combinations suggested that early article use can be distributed across a variety of nouns, and that such usage does not seem appropriately characterized as a pattern of limited semantic scope. (CB)

Applies a theoretical framework that encompasses cultural and social regulation of mother-child speech to observations of discourse between three mothers and their two-year-olds. Maternal speech was semantically contingent in the sense that both partners in the conversation were jointly focused on a shared topic of concern. (Author/CB)

This study used semantic differential scales to compare the perceptions of male librarians among undergraduates, graduate students, and university librarians. It was found that male librarians believe that they are viewed in a negative light, while other respondents reported positive perceptions of male librarians. (40 references) (Author/CLB)

Investigates the processes involved in the learning of Arabic subject-verb agreement by Australians. It is hypothesized that the amount and direction of information encoding motivated by certain semantic categories as well as the availability of discourse cues would influence the learners' performance in subject-verb agreement tasks. (27…

Describes the role of natural language processing (NLP) techniques, such as parsing and semantic analysis, within current language tutoring systems. Examines trends, design issues and tradeoffs, and potential contributions of NLP techniques with respect to instructional theory and educational practice. Addresses limitations and problems in using…
