Principles of program evaluation research are outlined so that bilingual education program coordinators can conduct methodologically acceptable program evaluations. The three basic principles of evaluation research are: identification of the program participants, definition of the program intervention, and assessment of program effectiveness.…

A quantitative method, meta-analysis, is used to integrate research findings from a representative group of 38 coaching studies. Because different studies reported results on different scales, effect size was used to transform all results to a common metric. This meta-analysis showed that there are two distinct literatures on the effectiveness of…

This paper compares five growth measures using the High School and Beyond database. The measures are: (1) simple gain (posttest minus pretest); (2) difference between group means; (3) percentage of students who scored higher on the posttest than the pretest; (4) percentage of items missed on the pretest which are subsequently answered correctly on…

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…

Self-selection bias poses a major threat to the validity of research findings in naturalistic, quasi-experimental, or single-group designs. A new method of addressing self-selection bias in naturalistic evaluations of prevention programs was implemented. The study, involving voluntary exposure to multicomponent interventions, was developed and…

Three British studies recently compared the examination results of pupils from comprehensive schools with those of selective schools. Each study reached somewhat contrasting conclusions. Major differences among the studies are discussed in order to clarify reasons for the contrasting interpretations and to illustrate the major difficulties in…

This paper cites modest beneficial effects of early intervention for children with developmental disabilities or children at risk, and examines two specific program features, age of start and family involvement. The moderating influence of the level of disability severity is also analyzed, and future directions for improving early intervention…

A review of the literature is presented on developmental mathematics courses in two- and four-year colleges and universities. The paper is organized within the categories of status studies, placement, program evaluation, class management, student characteristics, and thought processes. Highlights of the report include: (1) an average of 2.0…

Following a discussion of various methods of evaluating the effectiveness of developmental programs, this paper presents a research design for the evaluation of a developmental math program. First, the paper examines the objectives and benefits of conducting formative and summative program evaluations. The paper then identifies the single group…

This paper deals with a required methods course, based on the national curriculum of science and technology for junior high schools. The course participants are pre-service teachers who study towards a B.Sc. degree in education in science and technology parallel to their studies in one of the faculties of sciences or engineering. Working in small…

Even though attrition presents a serious threat to the validity of longitudinal research, there is a lack of standardization for reporting it. To examine the effectiveness of four tests for attrition -- two for external validity and two for internal validity -- the tests were applied to two large scale projects: the first, Project HASP, is a…

In an effort to review the effectiveness and the impact of the Office of Institutional Research (OIR) at El Paso Community College (EPCC) and to identify and report any significant problems with the quality of service being provided to the college president and other key policy and decision makers, an evaluation plan and survey test instrument…

Reviews the research on the effectiveness of five thinking skills training programs: Instrumental Enrichment, Philosophy for Children, Structure-of-Intellect (SOI), Problem Solving and Comprehension: A Short Course in Analytical Reasoning, and Odyssey. Compares and contrasts the content of each program and describes the relative lack of adequate…

Describes an evaluation plan and preliminary results for the ATS-6 satellite interactive telecommunication program for teaching basic science and clinical diagnosis at sites remote from an established medical school (University of Washington). This study assesses the technical feasibility, interaction characteristics of the education programs, and…

Maintains that empirical curriculum development (evaluating a curriculum as one develops it) can be a useful tool for drug abuse prevention efforts. Presents a model of a systemic process of empirical development that considers variables such as manipulation checks, interest, belief changes and perceived helplessness. Discusses research…
