This paper reviews and synthesizes the available literature concerning the effects of intervention programs at the secondary and higher educational levels. In achieving an understanding of the design of these efforts it is important to recognize that the first projects, e.g. the Demonstration Guidance Project, Higher Horizons, established a…

This report contends that the preliminary negative evaluation of the Rough Rock Demonstration School (RRDS) was due more to the investigators' culture shock than the actual situation. RRDS, an experimental school, is unusual in that is administered mainly by Navajos. Thus the appearance of this school, which offers a bilingual and bicultural…

Point of entry problems are faced by evaluators when asked to start an evaluation at an inappropriate time or to perform an inappropriate study. The fundamental purpose of evaluation is to help improve services. Guidelines are presented for choosing when to do a context, input, process, or product evaluation. (GDC)

A solution to the problem of specification error due to excluded variables in statistical models of treatment effects in nonrandomized (nonequivalent) control group designs is presented. It involves longitudinal observation with at least two pretests. A maximum likelihood estimation program such as LISREL may provide reasonable estimates of…

Discusses the need for awareness of real and potential problems in educational evaluation approaches, kinds of problems there are with true experimental designs and with quasi-experimental designs, and the criteria applied by the Joint Dissemination Review Panel to its review of educational programs. (MF)

Reviews a number of issues relating to the results of evaluation studies: standards of acceptability; clinical vs. statistical significance; fallacies in the use of theory; and program, theory, measurement, and design failure. (Journal availability: Subscription Manager, MOBIUS, University of California Press, Berkeley, CA 94720.) (SK)

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)

Two related problems are discussed: developing a methodology which (1) will not require full commitment of a local education agency to new techniques which may be ineffective in local settings and (2) will allow graceful abandonment of a new technology that may be proved ineffective. An example is discussed. (CTM)

An analysis of five funding competitions sponsored by the Office of Special Education and Rehabilitative Services in the area of secondary special education and transitional services research found that the projects have not emphasized community-level change to facilitate lasting improvements in youths with disabilities and have not taken a…

Evaluation issues pertaining to the Intelligent Vehicle Highway System are discussed. Transportation is an area that clearly illustrates how technology is outrunning social science. Those responsible for the evaluation of programs and options must assume responsibility for spelling out the destructive consequences of focusing only on technology.…

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)

Strengths and weaknesses of three types of semiquantitative methods used by the federal government in research impact assessment are presented, and examples of their use are reviewed. These include the classic retrospective method, another retrospective approach, and accomplishments books used by selected research-sponsoring organizations. (SLD)

This article reviews the principal methods economists and cost benefit analysts use in evaluating research. Two common approaches are surplus measures (combinations of consumer and producer surpluses) and productivity measures. Technical difficulties and political and organizational constraints are discussed for these measures. (SLD)

Presents two groups of text encoding problems encountered by the Brown University Women Writers Project while using Standard Generalized Markup Language (SGML) to create a database of book transcriptions: dual emendation and correction, and multiple hierarchies. Offers several possible approaches to these encoding problems and analyzes the issues…

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…
