The What Works Clearinghouse (WWC) identifies existing research on educational interventions, assesses the quality of the research, and summarizes and disseminates the evidence from studies that meet WWC standards. The WWC aims to provide enough information so educators can use the research to make informed decisions in their settings. This…

Optimal levels of treatment fidelity, a critical moderator of intervention effectiveness, are often difficult to sustain in applied settings. It is unknown whether performance feedback, a widely researched method for increasing educators' treatment fidelity, is an evidence-based practice. The purpose of this review was to evaluate the current…

The purpose of this paper is to provide a basis for judging the adequacy of evaluation plans or, as they are commonly called, evaluation designs. The authors assume that using the procedures suggested in this paper to determine the adequacy of evaluation designs in advance of actually conducting evaluations will lead to better evaluation designs,…

Graduate students in the health sciences who hope to become independent researchers must be able to write up their results at a standard suitable for submission to peer-reviewed journals. Bayesian analyses are still rare in the medical literature, and students are often unclear on what should be included in a manuscript. Whilst there are published…

Evaluative statements from alumni have legitimacy with both internal and external stakeholders. Thus, alumni studies can provide valuable evidence of institutional effectiveness and lend themselves to both locally designed and commercial survey instruments for data collection. Under ideal conditions, the results of alumni studies equip faculty and…

To address methodological challenges in research on psychosocial interventions for autism spectrum disorder (ASD), a model was developed for systematically validating and disseminating interventions in a sequence of steps. First, initial efficacy studies are conducted to establish interventions as promising. Next, promising interventions are…

As a step toward developing a standardized measure for evaluating the impact of child protective services, three indices were developed: the abuse index, the neglect index, and the sexual abuse index. Each is composed of physical indicators of the problem and social and behavioral indicators found to be statistically correlated with physical…

Intended for those who are concerned with evaluation but do not have an extensive background, this textbook helps students, scientists, evaluators, and administrators conduct and interpret evaluations. It deals with evaluations in all social action programs--health, education, and welfare. The focus is on basic procedures, rather than on theory,…

The purpose of phase 3 of Project IMPACT (a project to assess the impact of vocational education research and development on vocational education programs in Illinois) was to review, further conceptualize, and refine the impact assessment system for vocational education research and development efforts proposed during fiscal 1989. The following…

This handbook for state and local education agencies is intended as a reference to assist in initiating and/or improving follow-up systems or studies of former vocational students. A companion volume focuses on follow-up studies of special populations (see Note). Section 1, which contains information on use of the handbook, also introduces the…

This handbook for state and local education agencies is intended as a reference to assist in initiating and/or improving follow-up systems or studies of former vocational students classified as special populations. The handbook is a complement to Evaluation Handbook: Guidelines and Practices for Follow-Up Studies of Former Vocational Students,…

The orientation of this report is that of identifying educational projects which can be considered truly exemplary. The bulk of the report consists of a 23-step procedure for validating the effectiveness of educational programs using existing evaluation data. It is not intended as a guide for conducting evaluations but rather for interpreting data…

A three-year project was undertaken by the National Center for research in Vocational Education (Ohio State University, OH) to investigate time on task in vocational and technical classes. During the first year of the project, researchers used the direct observation method to collect time-on-task data pertaining to 10 teachers and 186 students in…
