This paper examines how controlling statistically for baseline covariates (especially pretests) improves the precision of studies that randomize schools to measure the impacts of educational interventions on student achievement. Part I of the paper introduces the concepts, issues, and options involved. Parts II and III present empirical findings…

As computer aided instruction (CAI) and distance learning become more popular, a model for easily evaluating these teaching methods must be developed, one which will enable replication of the study each year. This paper discusses the results of a study using existing dependent and independent variables to evaluate CAI for developmental reading…

Provides a detailed introduction to the variety of purposes for which evaluation research may be used and to the range of methods currently employed in the practice of that field. Uses specific examples, where appropriate, to provide concrete illustrations of both the goals of evaluation researchers and the methods used. (Author)

Factors involved in pre-planned and post-planned evaluation of program effectiveness are compared: (1) reliability and cost of data; (2) internal and external validity; (3) obtrusiveness and threat; (4) goal displacement and program direction. A model to help program administrators decide which approach is more appropriate is presented. (Author/MH)

Strasser and Deniston's own analysis (TM 504 254) shows that post-planned evaluations are unsuitable substitutes for pre-planned evaluations. When viewed as post-experimental interviews, however, post-planned evaluations can produce valuable information which complements traditional experimental and quasi-experimental evaluations. (MH)

Meta-analysis of 143 effect sizes in 43 studies of adventure programming for adolescents found an overall effect size of 0.31. Summary effect sizes of outcome categories differed significantly among categories, however. Effect size was related to program length and participant age but not to delinquent status. Discusses the lack of pertinent…

This paper examines the educational impacts of the Berkshire Wireless Learning Initiative (BWLI), a pilot program that provided 1:1 technology access to all students and teachers across five public and private middle schools in western Massachusetts. Using a pre/post comparative study design, the current study explores a wide range of program…

In 1991, the Office of Special Education and Rehabilitation Services (OSERS) authorized, under the Individuals with Disabilities Act (IDEA), a specific grants program. The State Systems for Transitions Services for Youth with Disabilities Program made available competitive 5-year grants to individual states for establishing responsive state…

Perhaps no facet of long-term care (LTC) research has received as much attention as the evaluation of community-based LTC demonstrations. Recent thinking has called into question the validity and policy relevance of the findings of these studies, yet their efforts will continue to receive strong financial backing. The time has come for LTC…

A repeated measures design was used to assess the effects of a methadone maintenance program in several California locations. Subjects were 720 Chicano and Anglo men and women participating in rehabilitation programs for heroin addicts. The subjects were interviewed between 1978-1981, and the average follow-up time after initial treatment was 4-6…

Part of a volume which explores current issues in service delivery to infants and toddlers (ages birth to 3) with handicapping conditions, this chapter presents program evaluation as a comprehensive process comprising three phases: input, process, and output. Three program evaluation models are summarized: Tyler's objective model, Scriven's…

To relate the design of open education programs to their outcomes, the authors surveyed 72 research studies on the effects of open education and examined the methods and findings of three previous literature surveys on this topic. The 72 studies were divided by an objective statistical test into those showing large effects of open education and…

The most essential element in the Research and Development (R&D) process is the provision for repeated field testing, evaluation, and revision until the product reaches its objectives. This process can be implemented to improve the instructional process in two ways: to improve the instructional skills and strategies of teachers; and to develop…

At the request of a Senate subcommittee, this report describes the value of conducting impact evaluations, describes their current use in evaluating selected early childhood education and care programs, and discusses the value of other types of early childhood education and care studies currently promoted and sponsored by the Departments of Health…

The Child Nutrition Act of 1998 authorized demonstration pilot projects in up to six school food authorities and a rigorous evaluation to assess the effects of providing free school breakfasts to elementary school children. This report describes the evaluation strategy and data collection plans. Part 1 of the report provides background…
