The study tests the appropriateness of multiplicative versus additive expectancy-valency models for grouping motivational force decisions of 82 undergraduate students. Arguments are offered favoring a non-nested regression models analysis over a traditional hierarchical analysis of nested regression models. Discriminant analysis indicated one of…

Patent trend analysis, a process developed at Batelle Pacific Northwest Laboratories, can help businesses understand the direction of technological change and compete more effectively in the marketplace. The procedure involves tracking the linkages among new patents in an area, the age of earlier patents cited, and the companies involved. (IS)

This paper summarizes findings from studies linking early reading problems and spoken language deficiencies and reviews the results of two longitudinal studies which show that inferior performance in kindergarten tests of language skills may presage future reading problems in the first grade. Procedures are suggested for kindergarten screening and…

Examination of the predictive validity of the Gesell School Readiness Screening Test with 84 kindergarten-age children found the procedure effective in predicting child success or failure in kindergarten and that within four-six years the chronological age of children entering kindergarten is unrelated to eventual success of failure in…

Presents a computer program which predicts the weather based on student input of such weather data as wind direction and barometric pressure. Also provides procedures for several hands-on, weather-related activities. (JN)

This study directly compared the effects of a picture selection response with a rotational one. Eighty preschool children were compared on the response modes. Half the children indicated perspective inferences by selecting from a set of photographs while the others rotated a replica. Children were tested on three nonegocentric perspectives.…

Reported is a study exploring the hypothesis that gains in reading achievement result when teachers assess the students and predict improvements in reading ability. (GW)

Discussed are the role of the social studies supervisor and the future directions the role might take. Suggested are four methods of improving supervisor effectiveness, including in-service programs, advanced teacher training, and improvement of supervisory skills. For journal availability, see SO 505 192. (Author/DB)

This study attempted to shed light on the role of items cued to be remembered in the forgetting of items cued to be forgotten. (Author)

Evaluated are 28 classroom variables from 33 eighth-grade science classes to identify variables useful in predicting achievement. (SL)

Trends in relative success rates and in subjects studied by both sexes cast serious doubt on the adequacy of the "female disadvantage model" as a guide to action. It is suggested that, before any further commitment is made to large scale programs based on "disadvantage models," there should be careful consideration of possible alternatives.…

A review of data on parent-offspring resemblances in intelligence is presented in the context of correlation, regression and variance predictions from the polygenic model and an environmental model. (Editor)

The purpose of this article is to suggest a number of trends that may impact the field of aging during the next 25 years. The research reported addresses both macro- and micro-societal changes and is based in large part on historical evidence. The editor's comments are presented following the article. (Author)

Discusses research which explored the hypothesis that students who are fast starters in a personalized system of instruction psychology course would perform better and maintain faster course progress rates than slow starters. Findings indicate that students' starting pace is predictive of course performance and subsequent progress rates.…

This article looked at non-experimental data via an ordinary least squares (OLS) model and compared its results to ridge regression models in terms of cross-validation predictor weighting precision when using fixed and random predictor cases and small and large p/n ratio models. A majority of the time with two random predictor cases, ridge…
