This study identifies multiple profiles of successful essays via a cluster analysis approach using linguistic features reported by a variety of natural language processing tools. The findings from the study indicate that there are four profiles of successful writers for the samples analyzed. These four profiles are linguistically distinct from one…

The participants were 866 8th graders from 61 classes and 745 11th graders from 46 classes. Most of the variance in homework environment management occurred at the student level, with classmates'…

Longitudinal research on the links between intelligence and health behaviors among adolescents is rare. We report longitudinal data in which we assessed the relationships between intelligence as assessed in Grade 7 and consequential health outcomes in Grade 11. The mean age of respondents (N = 420; 188 males, 232 females) was 12.30 years (SD =…

Student difficulty in the study of probability arises in intuitively-based misconceptions derived from heuristics. One such heuristic, the one of note for this research study, is that of representativeness, in which an individual informally assesses the probability of an event based on the degree to which the event is similar to the sample from…

The validity of the Self Concept as a Learner Revised (SCALR) inventory was studied. The construct issue of academic self-concept was explored by comparing the SCALR to the academic portion of the Multidimensional Self Concept Scale (MSCS). The SCALR contains 44 items (four scales of 11 items each). The SCALR version for grades 7 through 12 was…

This study tested the multifaceted, hierarchical structure of self- concept (SC) against alternative models and determined whether academic SC can be discriminated from academic grades. Results supported the multidimensional interpretation of SC and demonstrated that general SC could be interpreted as distinct from but correlated with academic SC.…

This study investigated whether alcohol use by public school students differs in its relationship to other variables when analyzed on the individual level versus the aggregated group level. The study presents a model and a set of analytic techniques for studying the ways that school and individual variables relate to adolescent alcohol abuse.…

Twenty-five eleventh grade classes were taught two social studies concepts, sovereignty and comparative advantage, using written or oral methods. Methods differed in their use and sequence of examples to explicate definitions. Finds using examples increased concept attainment. Suggests sequence was important for the more complex, relational…

This report describes the development and validation of the Unisex ACT Interest Inventory (UNIACT). In contrast to other interest inventories in common use, the UNIACT contains scales on which males and females receive similar scores. In the development of the UNIACT, more than 200 potentially sex-balanced items were administered to 10,211 people,…
