Analyzed are some common features of three studies on manual communication which cause the author to doubt whether manual communication does best prepare hearing impaired children for the hearing world, as the studies would imply. (KW)

Reviewed are: Research in Education by John W. Best, and Research Methods and Design for Education by J. H. McGrath, both written for graduate level courses. (DB)

Level of cognitive development was not significantly related to humor appreciation for either novelty or incongruity humor in 30 boys at each of three age levels: 5, 7, and 9. (WY)

Investigates the development of gerontological knowledge and its translation to practice. Discusses design, relevance, and dissemination of theory, and offers suggestions to practitioners for implementing research theories. Encourages both researchers and practitioners to make attitudinal changes to eliminate communication barriers. (University of…

Presents arguments concerning the effectiveness of attributional counseling in light of possible deterioration effects. Discusses when attributional interpretations should be used, the amount of change such interpretations provided in research participants, and lack of a control condition in previous research design. (WAS)

Discusses the use of hypothesis testing research and hypothesis generating research designs. Researchers investigating teacher development should continue to use hypothesis generating research designs to depict, relate, and conceptualize information in this area. Hypothesis testing research designs could check the accuracy of these initial…

What is meant by "normal science" is described, the first three steps in the "route to normal science" are outlined, and an example is given in which the trend toward research consensus is apparent. This involves current work on learning addition and subtraction. (MNS)

Incidence sampling is a parsimonious method whereby a large number of examinees can be measured on many variables (such as test items) to assess group characteristics. Parameters used to describe an incidence sample are estimated using the theory of generalized symmetric means and generalizability theory. (Author/JKS)

Analysis of 230 major articles in the "Journal of Medical Education" shows 91 percent of those reporting medical education research had less than a 50-50 chance of detecting a small treatment effect. Similar low statistical power was found in other disciplines. Guidelines for reporting research are provided. (MSE)

Second in a three-part series, this article provides suggestions for the development of theoretical models in which issues and questions in economic education can be conceptualized and formally stated as empirically testable hypotheses. (Author/RM)

According to the stage-learning hypothesis, children's ability to learn is constrained by their pretraining stages of cognitive development. Some procedures for obtaining unconfounded tests of this hypothesis are developed in this paper, and some applications to factorial experiments are considered. (Author/BW)

Basic characteristics of survey as a research study are discussed. Issues associated with survey research, potential uses of survey research as a strategy in science education, and potential problems jeopardizing survey studies are also discussed. (JN)
