This article derives an updated cost-benefit ratio for the High/Scope Perry Preschool Program, an intensive preschool intervention delivered during the 1960s to at-risk children in Ypsilanti, Michigan. Because children were randomly assigned to the program or a control group, differences in outcomes are probably attributable to program status.…

This article presents a control group study of the influence of a partnership-centered, community-based learning program on students' academic writing. The improved writing of first-year students in the Chicago Civic Leadership Certificate Program (CCLCP), we argue, results from the deeply situated learning that took place in the context of…

This study examines whether aural processing of input in a situation of implicit instruction can build a knowledge base that is available for both comprehension and production tasks. Fifty-five Dutch students learned a miniature linguistic system based on Spanish. Three training conditions were compared in which noun-adjective gender agreement was…

This study examined the effects of teacher feedback from Reading Curriculum-Based Measurement (R-CBM) progress results for low-performing students in general education classrooms. Participants included 44 second-grade teachers and 184 students in their low reading groups. After 5 weeks of progress monitoring, teachers in the two experimental…

This article presents a guide that seeks to provide assistance to educational practitioners in evaluating whether an educational intervention is backed by rigorous evidence of effectiveness, and in implementing evidence-based interventions in their schools or classrooms. The guide is organized in four parts: (1) A description of the randomized…

Question-asking is a basic skill, required for the development of scientific thinking. However, the way in which science lessons are conducted does not usually stimulate question-asking by students. To make students more familiar with the scientific inquiry process, we developed a curriculum in developmental biology based on research papers…

This pilot study explores the use of Internet Relay Chat facilities such as ICQ in an independent-use mode, as a vehicle for potential English language enhancement. In a small-scale study, a number of Hong Kong secondary school students (Grades 7-10) agreed to participate in an on-line "chatting" programme (in a text-only mode) for a minimum of 20…

Access to the textual world of academia requires that learners are familiar with the critical open-ended questioning stance demanded by textuality. Anecdotal evidence suggests that learners registered for the Bachelor of Education Honours degree are unable to generate appropriate questions to interrogate academic text, impacting on their ability…

The authors assessed the extent to which a generative prereading activity known as Story Impressions (SI), or composing a guess from clues, influences passage recall relative to a more passive prereading activity of reading a Content Preview (CP). The results from 74 eighth-grade students indicated the CP groups equaled the reading-only control…

A 12-week retention program designed to assist at-risk students with test-taking, study and career skills through individual and group counseling was examined. Sixty-nine percent of the program participants attained a cumulative GPA [greater than or equal] 2.0 by the end of the intervention compared to 43% of the control group. Further, 55% of the…

Purpose: We assess the effects of racial or ethnic concordance between caregivers and interventionists on caregiver attrition, change in depression, and change in burden in a multisite randomized clinical trial. Design and Methods: Family caregivers of patients with Alzheimer's disease were randomized to intervention or control groups at six sites…

Purpose: This study explores the effects of participation in a program designed to enrich friendship and reduce loneliness among women in later life. Several hypotheses based on the need to belong, socioemotional selectivity theory, and the social compensation model were tested. Design and Methods: Study 1 involved two measurement points, one at…

Reduced verbal working memory capacity has been proposed as a possible account of language impairments in specific language impairment (SLI). Studies have shown, however, that differences in strength of linguistic representations in the form of word frequency affect list recall and performance on verbal working memory tasks. This suggests that…

This study investigated the effectiveness of combining conceptual change text and discussion web strategies on students' understanding of photosynthesis and respiration in plants. Students' conceptual understanding of photosynthesis and respiration in plants was measured using the two-tier diagnostic test developed by Haslam and Treagust (1987,…

Two experiments examined reliability and classification accuracy of a narration-based dynamic assessment task. Purpose: The first experiment evaluated whether parallel results were obtained from stories created in response to 2 different wordless picture books. If so, the tasks and measures would be appropriate for assessing pretest and posttest…
