The investigator compared the linguistic characteristics of Spanish and English language samples taken from English language learners (ELLs) diagnosed with an academic learning disability (LD) and ELLs in general education to determine if the errors and characteristics of their language use differ. There was a statistically significant difference…

Service learning experiences hold the potential to significantly influence participants' view of cultures other than their own. This qualitative study examines how service learning affects preservice teachers' attitudes about working with students from diverse backgrounds. Two groups of preservice teachers enrolled in a reading methods course…

This study investigated differences in attention and learning among Guatemalan Mayan and European American children, ages 5-11 years, who were present but not addressed while their sibling was shown how to construct a novel toy. Each child waited with a distracter toy for her or his turn to make a different toy. Nonaddressed children from Mayan…

The current study evaluated the use of a manualized social skills program, Superheroes Social Skills, to increase the use of prosocial behaviors and decrease the use of aggressive behaviors for children with externalizing behaviors. The training was implemented by a school psychologist in a pullout group with four children with high-incidence…

This comparative study examined discourse and opportunities for interaction in two mathematics education methods classes, one face-to-face and one synchronous, online. Due to the content taught in the course, this study also sought to determine prospective mathematics teachers' understanding of variability and the role of discourse in each…

Two children's conversations with adults were examined for reference to moral issues using transcripts of archived at-home family talk from the Child Language Data Exchange System (CHILDES) database (MacWhinney, 2000). Through target words (e.g., good, wrong, mean) in transcripts of two children between ages 2.5 and 5.0 years, 1,333 moral…

The use and understanding of self-presentational display rules (SPDRs) was investigated in 21 children with high-functioning autism (FHA), 18 children with Asperger's disorder (AspD) and 20 typically developing (TD) children (all male, aged 4- to 11-years, matched on mental age). Their behaviour was coded during a deception scenario to assess use…

Examines two models to study the consequences for coding efficiency of sample fluctuations, a specific type of error in the statistics on which data compression codes are based. The possibility that random fluctuation can be exploited for data compression is discussed. (six references) (KRN)

Reading rate data was collected from both print and braille readers in the areas of mathematics and literary braille. Literary braille data was collected for contracted and uncontracted braille text with dropped whole-word contractions and part-word contractions as they would appear in the Unified English Braille Code. No significant differences…

Differential performance results occur when a specific population subgroup achieves a passing rate which is significantly lower than that of the normative reference group. African Americans do less well, in general, on all types of assessments, including constructed-response tests. The present study examined the writing styles of African American…

Contrasts or comparisons can be used to investigate specific differences between means. Contrasts, as explained by B. Thompson (1985, 1994) are coding vectors that mathematically express hypotheses. The most basic categories of contrasts are planned and unplanned. The purpose of this paper is to explain the relative advantages of using planned…

Identifies four components of a good predictive lossless image compression method: (1) pixel sequence, (2) image modeling and prediction, (3) error modeling, and (4) error coding. Highlights include Laplace distribution and a comparison of the multilevel progressive method for image coding with the prediction by partial precision matching method.…

This paper discusses grounded theory as one of the qualitative research designs. It describes how grounded theory generates from data. Three phases of grounded theory--open coding, axial coding, and selective coding--are discussed, along with some of the issues which are the source of debate among grounded theorists, especially between its…

A study with students enrolled at an urban technical college compared learning of HTML coding across three Web-based program versions. One group received examples providing factual information about the source code (Facts group). A second group was presented with a step-by-step description of the source code (Procedures group). The third group was…

In this study the authors have looked at the use of interactive whiteboards (IWBs) in Mexico from a linguistic anthropological perspective. Twenty lessons were video recorded to compare the use of IWBs and traditional boards in different areas of the curriculum in primary schools. Data were analysed as a set of sequenced communicative events in…
