We reviewed 14 experimental studies comparing different preference assessments for individuals with developmental disabilities that were published in peer-reviewed journals between 1985 and 2012. Studies were summarized based on the following six variables: (a) the number of participants, (b) the type of disability, (c) the number and type of…

This article reviews ten predictive validity studies of the Swedish Scholastic Assessment Test (SweSAT). A primary result is that the predictive validity of the SweSAT seems to be highly dependent upon the study programme being examined; that is, the predictive validity is better at some programmes than others. When compared with the…

Contrary to prior assumptions, matched groups differed from each other nearly as much as they did from the unmatched group. This has implications for the ability to generalize from interspousal data even when comparison groups are matched on several traditional variables. (Author)

Stability and predictive validity in the language and play development of 41 toddlers were studied. Links between language and symbolic play of toddlers were examined at 13 and 20 months in terms of homotypic, heterotypic, or mediated models of association. In the homotypic model, performance on a variable is related to performance on the same…

Tested models of interests by examining the significance of disconfirmed ordinal predictions. Examined data regarding Holland's hexagonal model and Roe's circular ordering. Tested adequacy of the hierarchical model and compared significance of the disconfirmed predictions of the hierachical model to that of the hexagonal-circular model. (Author)

Findings from a study of 302 California students suggest that there are no statistically reliable differences, at any grade level, first through fourth, between those learners who had attended preschools and those who had not. (IAH)

Provides an in-class activity that enables students in research methods to learn about survey design and multiple regression. Explains that the students developed questionnaires in order to generate five items, as set in a multiple regression equation, that would best predict a particular outcome. Discusses benefits and drawbacks. (CMK)

To enhance knowledge of media consumption processes, a study compared the abilities of six alternative gratification models to predict media satisfaction, specifically, satisfaction with television news. The models were three different formulations of gratifications sought/obtained discrepancies--two emphasizing gratifications obtained and one…

Phase III, the development and testing of experimental programs to reduce the rate of student attrition, of the Northern California Cooperative Research Project (NORCAL) on Student Attrition is reported upon. Phase I of the program was the description and identification of characteristics associated with attrition among Junior College students…
