Sets an agenda for improving instructional research conducted with classical quantitative experimental or quasi-experimental methodology. Includes guidelines regarding the role of a social perspective, adequate conceptual and operational definition, quality instrumentation, control of threats to internal and external validity, and the use of…

The educational system has not been particularly successful in teaching thinking skills. In order to do so, it is necessary to identify what thinking skills are and understand their development. Current research and design of future research are discussed, as is the problem of transfer. (MT)

Explains the characteristics and importance of random assignment in experimental research on education. Considers factors supporting causal inferences, the nature of "assignment units," differences between random sampling and random assignment, the characteristics of randomization tests, forms of random assignment, and effects of experimental…

Investigators interested in conducting school health research face many challenges. This article focuses on an analysis of research designs and measurement issues that most frequently confront school health researchers. (Author/DF)

The use of large-N group comparison research methods based on a nomothetic model is compared with idiographic methods employing single-system designs and intensive study of the individual. Limitations of the nomothetic model and advantages of the idiographic approach are presented. (SK)

Describes the use of repeated-measures designs in the study of whole families, specifically differences in perception between family members. Addresses the specific advantages and disadvantages of these designs; analysis of variance and multivariate analysis of variance applications; and practical issues of assumptions, multiple comparison,…

The impossibility of getting totally objective curriculum evaluation research is examined. (DE)

Reviews various problems which create problems in research design for the classroom and advocates a divorce between research and evaluation. Bibliography. (MB)

Post-hoc blocking and analysis of covariance (ANCOVA) both employ a concomitant variable to increase statistical power relative to the completely randomized design. It is argued that the advantages attributed to the block design are not always valid and that there are circumstances when the ANCOVA would be preferred to post-hoc blocking.…

Points out the problems in designing and evaluating research on writing courses. (JL)

Professional evaluators are often called upon to analyze data produced by a catastrophically inadequate evaluation design. A remedial strategy involving diagnosis of error, application of a corrective procedure and sensitization of program personnel of the need for a more sophisticated stance, is proposed and illustrated with a case study.…

Manipulated two aspects of the general empathy training situation in an attempt to produce higher levels of "empathic responding" following a brief training program. Results showed the experimental manipulations increased more empathic responses in the group asked to display competence than in the group asked to learn "empathic responding."…

The influence of maternal stimulation on infant exploratory behavior was examined in both a cross-sectional/ correlational study and an experimental study, in order to overcome the limitations on making causal claims that attend most research into maternal influence on infant development. (Author/DB)

Schools are social systems, not factories. Trying to develop a model of education accommodating this fact led John Goodlad to undertake a seven-year national study that he believes will give impetus to humanistic approaches to research while generating hypotheses that can be tested using traditionally objective research methods.
