Because human beings are different and are necessarily subjective, and because evaluation always involves the human factor, many problems arise. The problems may be compounded in third world settings because they have been studied less, and are less understood, and because evaluators are often from outside the setting and therefore bring…

The purpose of this paper is to summarize some of the author's logical and empirical reflections on the practice of using naturalistic techniques to conduct evaluations. The main assertion to be supported by these reflections is that naturalistic evaluation is possible and in some cases powerful. This assertion is supported through a review of (1)…

The impact of various definitions of the term "policy" on the nature and outcomes of policy analysis is illustrated by noting a variety of definitions which are implied in the literature. These definitions are applied to exemplar policy arenas to note their differential effect. The policy arenas discussed include the community…

Sixteen listeners (10 expert, 6 naive) judged the dissimilarity of pairs of voices drawn from pathological and normal populations. Only parameters that showed substantial variability were perceptually salient across listeners. Results suggest that traditional means of assessing listener reliability in voice perception tasks may not be appropriate.…

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.…

The thesis of this paper is that the humanistic mode of inquiry is underemployed in evaluation studies and the future evaluation of Follow Through could profitably use humanistic approaches. The original Follow Through evaluation was based on the assumption that the world consists of a single system explainable by appropriate methods; the…

This article examines the problem of definition in learning disabilities. It discusses the failure of conceptual definitions to provide a clear idea of what learning disabilities are, examines the true nature of available definitions as stipulative definitions, and notes the difficulty in conceptualizing and implementing operational definitions.…

Describes the methodology of White's survey of the perceived quality of library education programs, and examines the validity of using the results to rank library schools. The correlation between perception rankings and number of graduates per school are presented and discussed as a possible biasing factor in White's results. (CLB)

Develops generalizations for empirical evaluation of software based upon suitability of several research designs--pretest posttest control group, single-group pretest posttest, nonequivalent control group, time series, and regression discontinuity--to type of software being evaluated, and on circumstances under which evaluation is conducted. (MBR)

Presents five research designs--sequential analysis, value added analysis, nonequivalent dependent variables, regression discontinuity, cohort design--for studying computer-based teaching methods when a randomized two-group design is impractical; provides examples of studies employing these designs and decision flowchart; and discusses selection…

Discussion of difficulties in evaluating simulations and games as teaching techniques includes range of claims made for the techniques; variety available; lack of specificity of technique objectives at design stage; limitations of objective-oriented research; inherent difficulties of comparative evaluation against alternative techniques; and…

The family is an obvious group for whom problem solving effectiveness holds importance. Problem solving interaction refers to the manner in which the behavior of family members is organized to resolve situations in which there is an unachieved but attainable goal, and the means to overcoming the barriers to achieving the goal are not apparent, but…

This review focuses on methods used to identify language impairment in 72 published research studies from 1983-88. Test data were most frequently used, and expressive and receptive language were routinely assessed. Research problems included the lack of clarity regarding the specific number and identity of tests used and use of incomplete tests.…

Research procedures used to evaluate the intelligence of children with specific language impairment are reviewed. Almost half of the 167 studies did not include adequate descriptions of intelligence assessment. (Author/JDD)

The National Joint Committee for Learning Disabilities' definition of learning disabilities is presented, followed by a discussion of parameters to be considered in operationalizing the definition. Major definitional issues are then explored, including using testable and meaningful constructs, linking definitions to neuropsychological evidence,…
