The construct validity and internal consistency (reliability) of the 30-item form of the Leadership Behavior Descriptive Questionnaire (E. Fleishman, 1957; A. Halpin and B. Winer, 1957) as presented in a current leadership text was assessed. Classroom teachers and administrators (n=187) completed the instrument. Although reliability was found to…

Introduces basic principles of coding and decoding including the use of letter frequencies to decode secret messages by using the radio premium codes of Little Orphan Annie and Dick Tracy. (KHR)

A theoretical framework is presented for understanding difficulties in foreign language learning, based upon a linguistic coding model that hypothesizes deficits in phonological, syntactic, and semantic information processing. Incidence of linguistic coding problems in 22 college-enrolled or college-bound students who petitioned to have the…

Applies a Vygotskyan perspective to explain the speech activity of 16 third-year high school learners of Spanish, focusing on their talk about task, talk about talk, and use of English during a problem-solving speaking task. Findings suggest that not all speech activity between second-language learners during classroom communicative tasks is…

Discusses two mathematical ideas that come from the Incan and Mayan cultures: (1) the quipus, an Incan recordkeeping tool that encoded data via a logical-numerical system on spatial arrays of colored, knotted cords; and (2) the link between recording time and counting in the Mayan culture. (MDH)

Presents a method to enhance the teaching of computer programing to secondary students that establishes a connection between logic, truth tables, switching circuits, gating symbols, flow charts, and pseudocode. The author asserts that the method prepares students for thinking processes related to programing. (MDH)

Studied representation of text content and representation of the surface form of the text in two studies of native French speakers. Twenty-five subjects (aged 23-30) participated in Experiment 1, and 40 subjects (aged 23-30) participated in Experiment 2. Data confirm that readers retain the spatial location of words read. (Contains 18 references.)…

Examined facial expressions in relation to cognition in infants 2 to 8 months of age. A total of 48 subjects received an audiovisual stimulus contingent on arm movement, whereas 32 infants did not control the stimulus. Infants in the contingent group expressed greater interest and joy during learning and greater anger during extinction. (RH)

Analyzes the codification involved in learning geographical maps and the extent to which this codification is affected by characteristics of the task (map information content and varied instructions) and subject (experience level and cognitive development). Reports results from three groups of adolescents and two groups of psychology and geography…

Describes a three-month study of a family reunification program for abused and neglected children that explored the process and outcomes of service delivery. The coding scheme measured both the time used in and purposes of activities of the service workers. Discusses the implications of this method for practice, planning, and research. (TM)

Examines the effect of color-coding instructional materials for students identified as possessing different styles of learning. Subjects (107 college students) were classified as external, neutral, or internal locus of control. Results indicated a significant main effect in favor of the color-coded materials for specific educational objectives.…

This paper reports some methodological approaches to the analysis of argumentation discourse developed as part of the two-and-a-half year project titled "Enhancing the Quality of Argument in School Science" supported by the Economic and Social Research Council in the United Kingdom. In this project researchers collaborated with…

This study used neuroimaging and behavioral techniques to examine the claim that processing capacity limitations underlie specific language impairment (SLI). Functional magnetic resonance imaging (fMRI) was used to investigate verbal working memory in adolescents with SLI and normal language (NL) controls. The experimental task involved a modified…

User studies have been conducted for many years in the information and library science fields. In the archival world, this phenomenon has not been as common and less emphasis has been placed on collecting and studying the user's perspective in general. However, there are studies showing the "use" of these types of studies, particularly in the…

In 2 experiments, bimanual 1:1 rhythmic coordination was performed concurrently with encoding or retrieval of word lists. Effects of divided attention (DA) on coordination were indexed by changes in mean relative phase and recurrence measures of shared activity between the 2 limbs. Effects of DA on memory were indexed by deficits in recall…
