Background: Despite recent recognition of the need for preventive sexual health materials for people with intellectual disability (ID), there have been remarkably few health-based interventions designed for people with mild to moderate ID. The purpose of this study was to evaluate the effects of a computer-based interactive multimedia (CBIM)…

Purpose: This pretest-posttest study examined the feasibility of using a curriculum-level stuttering education and bullying awareness and prevention program to improve peer attitudes toward children who stutter and attitudes toward bullying. Knowledge about potential responses to bullying and students' liking of the program also were examined.…

In recent years, science education has placed increasing importance on learners' mastery of scientific reasoning. This growing emphasis presents a challenge for both developers and users of assessments. We report on our effort around the conceptualization, development, and testing the validity of an assessment of students' ability to reason around…

This paper includes a nontechnical description of methods for calculating effect sizes in intellectual and developmental disability studies. Different hypothetical studies are used to illustrate how null hypothesis significance testing (NHST) and effect size findings can result in quite different outcomes and therefore conflicting results. Whereas…

This study evaluated the relative effectiveness of home-based, community-based, and state-run early childhood programs across Cambodia. A total of 880 five-year-olds (55% girls) from 6 rural provinces in Cambodia attending State Preschools, Community Preschools, Home-Based Programs, or no programs were assessed twice using the Cambodian…

Students' everyday ideas of the greenhouse effect are difficult to change. Environmental education faces the challenge of developing instructional settings that foster students' conceptual understanding concept of the greenhouse effect in order to understand global warming. To facilitate students' conceptual development with regard to the…

This prospective, mixed-methods study investigated how the nature of joint activities between volunteer mentors and student mentees corresponded to relationship quality and youth outcomes. Focusing on relationships in school-based mentoring programs in low-income urban elementary schools, data were obtained through pre-post assessments,…

Science undergraduate courses typically cater to a mixed-learner cohort, with a diversity of motivations and skills. This diversity introduces pressure for designers of the practical laboratory curriculum. Students who are struggling with the course need a series of tasks that begin simply, and transition to more conceptually difficult material.…

Objective: This study was designed to extend the use of a memory training technique, known as the repetition-lag procedure, to Alzheimer patients. The specificity of this procedure is to target the process of recollection for improvement. Method: A group of 12 patients were trained individually for 6 h. The training procedure consisted of a series…

The present study examined the effectiveness of mechanical and meaningful production of output on the learning of English relative clauses by Iranian EFL learners. The study involved two groups of learners (N = 36) who completed a pre-test, three activities and a post-test over an 8-week period. The collaborative dialogue of the participants was…

A single-group pre- and post-test design was used to evaluate functional outcomes of a constraint-induced movement therapy (CIMT) protocol implemented in an outpatient therapy center. The participants were 29 children with hemiplegia, ages 1.6-19.1 years old. The less-involved upper limb was placed in a cast that was worn 24 hr a day, 7 days a…

This study investigated how the use of virtual manipulatives in integer instruction impacts student achievement for integer addition and subtraction. Of particular interest was the influence of using virtual manipulatives on students' ability to create and translate among representations for integer computation. The research employed a…

In order to support at-risk adolescents in their transition to high school, a school-based mentoring program was implemented for a group of 9th and 10th grade students. Due to the need for greater clarity regarding the impact of school-based mentoring on youth outcomes, a quasi-experimental study was conducted to examine the impact of one-to-one…

This report presents the results of the development of a methodological approach to provide empirical evidence that family literacy programs "work." The assessment techniques were developed within the action research project Literacy for Life (LFL) that the authors designed and delivered for 12 months, working collaboratively with three…

Scenario planning is often used by organizations to think about future uncertainties. However, what it does in terms of changing perceptions is difficult to assess and quantify. To address this need, this article builds on previous studies documenting the effectiveness of scenario planning. Specifically, this article contributes to the data on…
