While social programs are often assessed using short-term impact studies, longitudinal designs allow evaluators to capture change over time, identify longer-term outcomes, adapt instruments, and better understand participants in transition. A mixed methods design can be critical in understanding these dynamics; yet there is a lack of literature…

Written as four scenes that span a five-year period, this article examines the summative evaluation of an organized school reform programme in the United States from the teacher perspective. The study provides fine-grained details of how the evaluation of the particular reform effort went "awry" in the view of some teachers who directly…

This paper introduces an empirical strategy to estimate dynamic treatment effects in randomized trials that provide treatment in multiple stages and in which various noncompliance problems arise such as attrition and selective transitions between treatment and control groups. Our approach is applied to the highly influential four year randomized…

This paper on longitudinal/intervention research is divided into a discussion of the problems of this strategy and a working paper. Many of the problems are practical ones, concerning the uncertain trends of funding and the drifting of goals and priorities; all of the methodological problems and inadequacies of longitudinal research and…

This article discusses the experiences of the Research Utilization Laboratory (RUL) of the Chicago Jewish Vocational Service over a five-year period. The topic is approached in terms of the elements involved in the utilization of research and in terms of the problems the RUL encountered. (Author)

This paper discussed Consortium for Longitudinal Studies findings which demonstrate that, contrary to first impressions from earlier evaluation studies, early intervention preschool programs do have generally positive long term effects. A public information campaign to communicate these findings through all media is advocated. Problems of…

This document is designed to provide an understanding of the major longitudinal issues and problems, a rationale for longitudinal studies, and the advantages and disadvantages of using longitudinal studies for evaluation and accountability purposes when applied to vocational education. Following an introductory chapter, chapter 2 presents a…

Participants in this conference urged that arrangements be made for collecting and preserving information about participants, personnel, and organizations involved in the Follow Through Program, and for conducting long-term review studies of the program. Papers presented at the conference were: (1) "A Brief History" (Robert L. Egbert and…

Evaluation of Head Start has been based on four sources of information: (1) census surveys of children and families served and programs offered, (2) special research, projects on child development and experimental programs, (3) a longitudinal study of the development of low income children, and (4) a series of national evaluation studies.…

A longitudinal study was planned to track a class in a prekindergarten program to determine program effectiveness. There are many problems in conducting a longitudinal study, most of which revolve around the long-term commitment required. A carefully designed information system is important. For the study in question, computer software and…

Using examples from evaluations of the Emergency School Aid Act (ESAA) Basic Grants Program, the ESAA Pilot Program, and the sustaining effects of compensatory education programs, school and student attrition are discussed. As in the example cases, appreciable attrition can be expected in most longitudinal studies. The possible effects of this…

The methods and findings of studies of the effects and value of preschool education and compensatory education programs, such as Head Start, are reviewed. After introductory comments on ideological controversies and on terminology, section 1 focuses on evaluative studies of the immediate and long-term effects of preschool education and early…

Reviews the usefulness of existing national longitudinal studies in determining the effects of vocational education. It is clear that there is no unified vocational education program and that students in these programs differ markedly from those in other curricula. (SK)

In the research paper considered, Stahl and Miller compare the effectiveness of whole language/language experience programs versus basal reader approaches. The article is criticized for its lack of longitudinal data, alternative interpretations, and information concerning the broad goals of whole language approaches. (TJH)

This report examines participation rates in the Aid to Families with Dependent Children (AFDC) program. TRIM2, a microsimulation model that simulated the eligibility and benefit rules of the AFDC program on a state-by-state basis, showed that there had been a dramatic decline after 1981 in the rate at which AFDC families were applying for and…
