Regression to the mean (RTM) is often misunderstood. It is demonstrated that artifactual RTM depends fundamentally on the magnitude of measurement error at pretest. Adjustment usually involves estimating the measurement error and determining consequences, but even without adjustment, effects of RTM can be ameliorated. (SLD)

Effects of 2 types of oral language training programs on development of phonological awareness skills and word learning ability were examined for 48 kindergartners. Children receiving analytic and synthetic training improved significantly on both types of skills, but children receiving synthetic skills training alone improved only in blending…

The Cognition Rating Form (CRF), a scoring measure for the Rotter Incomplete Sentences Blank, was evaluated with 56 adolescent psychiatric patients and 102 high school controls. Concurrent validities and sensitivity rates indicated that the CRF shows promise as a thought sampling scoring measure. (SLD)

Describes analyses based on 35 studies on effectiveness of Grief Therapy. Clients with no-treatment control groups showed little improvement, possibly because of the relatively long delay between loss and treatment. Client selection procedures appear to contribute strongly to variability in effect size (ESs). The majority of studies involving…

This study examines the short-term effects of a two-way bilingual education program on the literacy development of students in kindergarten and first grade.

A randomized trial tested the efficacy of three curriculum versions teaching drug resistance strategies, one modeled on Mexican American culture; another modeled on European American and African American culture; and a multicultural version. Self-report data at baseline and 14 months post-intervention were obtained from 3,402 Mexican heritage…

Background: Many studies carried out in first language contexts tend to demonstrate the positive effects of activity programmes aimed at (1) developing metaphonological abilities and (2) developing language skills through active story listening on learning to read and to spell by first-grade students. Aims: This study seeks to extend previous…

This study assessed the effects of an environmental education (EE) course on college students' responsible environmental behavior and associated environmental literacy variables. This undergraduate course emphasized issue investigating-evaluation and action training. A nonequivalent control group design was used. The results of this study showed…

"Connections: Relationships and Marriage" is a high school marriage education curriculum designed to teach students how to develop healthy relationships and marriages. This study evaluated the effectiveness of this curriculum with 410 high school students who were in "Connections" or a control group. Although the effects were relatively small,…

Positive long-term effects of phoneme awareness training in kindergarten were found in this study with children of dyslexic parents. Thirty-five at-risk children (attending 26 different classes) participated in an intensive 17-week program in their regular kindergarten classes designed to help them improve in phoneme awareness. Follow-up measures…

The present experimental research examined whether framing early adolescents' (11- to 12-year-olds) learning activity in terms of the attainment of an extrinsic (i.e., physical attractiveness) versus intrinsic (i.e., health) goal and communicating these different goal contents in an internally controlling versus autonomy-supportive way affect…

This exploratory study investigated the effects of a structured writing strategy on the quality of expository compositions produced by 36 African-American college undergraduates with learning disabilities. The strategy was structured to assist students in developing a topic sentence and main ideas into body paragraphs, and in using transition…

In this study, the effect of conceptual-change-texts-oriented instruction to seventh-grade students' understanding of ecological concepts was investigated. Using information collected through interviews and related literature, the Ecology Concept Test was developed and administered to 58 elementary students in two classes of an elementary school…
