In this systematic evaluation of intervention research for transition-age autistic youth, we examined quality indicators in 193 group and single-case design intervention studies, which tested effects on 1258 outcomes. Behaviorally based interventions were the most common intervention type. We found significant threats to internal validity for the…

Programs that improve teaching effectiveness represent a core strategy to improve student educational outcomes and close student achievement gaps. This article compiles empirical values of intraclass correlations for designing effective and efficient experimental studies evaluating the effects of these programs. The Early Childhood Longitudinal…

The major aim of this manuscript is to bring together two important topics that have recently received much attention in child and adolescent research, albeit separately from each other: single-case experimental designs and statistical mediation analysis. Single-case experimental designs (SCEDs) are increasingly recognized as a valuable…

Sufficient attention and resources have been allocated to design-based research (DBR) to warrant review concerning if and how its potential has been realized. Because the DBR literature clearly indicates that this type of research strives toward both the development of an intervention to address a problem in practice and empirical investigation…

Contradictory findings from "well-implemented" rigorous evaluations invite researchers to identify the differences that might explain the contradictions, helping to generate testable hypotheses for new research. This panel will examine efforts to ensure that the large number of local evaluations being conducted as part of four…

Developing, implementing and evaluating programmes of intervention for children and young people on the autistic spectrum are challenging endeavours. In this paper, we adopt a critical approach to research in this area, and attempt to offer an alternative perspective for understanding and interpreting empirical evaluations. We outline and discuss…

Examines, in some detail, the process of evaluation and describes methods that have been used in evaluation applied to precollege education. (PEB)

A study was conducted to determine what particular outcomes are appropriate for use as criteria to evaluate vocational education programs. Procedures included (1) compiling a list of candidate outcomes, (2) conducting a literature and practice review, (3) formulating a strategy for having outcomes reviewed, (4) developing alternative outcome…

Described is a method to assist developers of mathematics programs to make formative evaluations. The method involves periodic achievement testing via item sampling. Details of item construction, periodic testing, and profile construction are given in a discussion of how this method was applied to modify a sixth-grade mathematics program. (JP)

This study investigates the development of mathematical ability and understandings and explores the use of math games as part of a global model of preschool program evaluation. Eighty-three children (aged 3 3/4 to 4 years) enrolled in several programs in the Mt. Druitt Early Childhood Project, North Ryde, Australia, participated in the study.…

A fundamental distinction is made between basic research which seeks out new, generalizable knowledge, and administrative research which provides information useful to decision makers who have a task to perform. Attention is then given to four types of administrative research: background research, formative research, summative research, and policy…

This study is one of the "knowledge development" activities mounted in conjunction with research, evaluation, and development activities funded under the Youth Employment and Demonstration Projects Act of 1977 (YEDPA). It focuses on the impacts of Job Corps participation on a large group of participants after 18 months to two years.…

A model for research and evaluation in outdoor education is presented in this paper which includes a bibliography of representative research in outdoor, experiential education. The model stresses close interaction between program designers and evaluators and rests on the premise that the strength of outdoor education--interaction between people,…

This volume (and volume 2 of this report) are products of the knowledge development effort implemented under the mandate of the Youth Employment and Demonstration Projects Act of 1977 (YEDPA). This report on assessment of the Job Corps presents a large array of studies ranging from rigorous impact and benefit-cost evaluations to survey of…
