The validity of various reliability-corrected procedures for adjusting for initial differences between groups in uncontrolled studies is established for subjects exhibiting linear fan-spread growth. The results are then extended to a nonlinear model of growth. (Author)

Six single subject experimental designs (AB, ABA, ABAB, Multiple Baseline, Changing Criterion, and Multi-Element Baseline) are examined in terms of their scientific rigor and practicality for school personnel. Design use may rest with the research question posed, behavior measured, teacher and personnel attitudes, and degree of scientific rigor…

The validity of the equipercentile hypothesis of the Title I Evaluation and Reporting System norm-referenced evaluation model was examined using 3,224 seventh- and ninth-grade students. Findings from confidence interval procedures contradicted the equipercentile hypothesis. There was a pattern of large gains for students not receiving any special…

Past research which used Piaget's model of cognitive development has suggested that historical understanding is a developmental construct. The present study, designed to test the theoretical adequacy of previous studies, shows that a new variable, information processing, could predict the level of historical understanding. (Author/CS)

Reports on a study that used a research design to evaluate three indices of context dependence (CD) and thereby obtain both absolute and comparative evaluations of the discriminant validity of high versus low CD as defined by the constructs that underlie the respective indices. (HOD)

Four ethical problems arose during the conduct of a fieldwork investigation of the life experience of three student teachers: acquiring permission to begin the study; limits on digging into personal lives; pitfalls of collaborative research; and the endangerment of participant image or position as a result of personal revelation. (Author/GPM)

Studies comparing the external characteristics of instructional methods have obscured the most important variable which accounts for learning from instruction: macroprocesses, or the frequency and intensity with which students cognitively process instructional input. Further research on macroprocesses may be a meeting point between the psychology…

Reviewed research on practicum supervision in terms of findings and research designs employed. Classified research according to counselor-supervisor similarity, training methods, and evaluation. Conclusions indicated no support for supervisor-counselor matching, support for experiential, modeling and didatic methods, and peer supervision. (Author)

Five symposium papers evaluate the usefulness of ideas associated with the life-span view for enriching, highlighting, or expanding issues, theory, and research pertinent to change processes during infancy, childhood, adolescence, and adulthood, and for intervention programs during these periods. (Author/MP)

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)

Presents an overview of an approach in training Black masters-level students in research, with emphasis on research design, data collection, data analysis, and computer usage. (JCD)

Describes major areas of progress in organization development (OD): progress in operationalizing the concept of change; progress in improving measurement; and progress in designing statistical procedures used to analyze OD intervention data. Suggests recent research developments point to a more solid base on which to build OD practice and theory.…

Addresses a number of ethical and methodological issues related to research involving vulnerable populations such as the frail elderly, when the research design calls for a control or nonintervention group. Techniques are presented for building a "limited" service component into the research design. (Author)

Outlines recent job-stress research indicating the impact of psychosocial stressors on employees. Presents four suggestions to broaden the job-stress research while keeping the psychosocial emphasis. Recommends that research be integrated with stress-management programs and suggests specific research designs for the evaluation of such programs.…

The Rasch model was used to equate reading comprehension tests of widely different difficulty for three groups of fifth grade students of widely different ability. Under these extreme circumstances, the Rasch model equating was unsatisfactory. (Author/CTM)
