The development and evaluation of valid assessments of scientific reasoning are an integral part of research in science education. In the present study, we used the linear logistic test model (LLTM) to analyze how item features related to text complexity and the presence of visual representations influence the overall item difficulty of an…

Failure to learn and generalize abstract relational rules has critical implications for education. In this study, we aimed to determine which training conditions facilitate relational transfer in a relatively simple (patterning) discrimination versus a relatively complex (biconditional) discrimination. The amount of training participants received…

Intraindividual variability (IIV) in cognitive speed, or moment-to-moment changes in ability, is a developmental phenomenon indicative of neurological integrity that increases gradually across adulthood. Past research has shown that IIV negatively covaries with cognitive performance, in which higher IIV at one occasion is associated with poorer…

The cumulative hierarchical assumption of Bloom's Taxonomy was tested by orienting American Australian subjects at four taxonomic levels to the same study material and administering an unexpected memory test. Moderate support was obtained for the cumulative hierarchical assumption, but it is concluded that the evaluation category is misplaced.…

Argues that current testing of student understanding provides insufficient information to a researcher investigating strategies for changing students' explanatory ideas. Outlines a new test based on recent work in child development. (DDR)

Describes a study of 323 fifth and sixth grade students which was conducted in Australia to examine cognitive processing of gifted children compared with normal and above average ability children. Highlights include the role of planning in cognition, tests used, and a factor analysis of results. Fifty-one references are listed. (Author/LRW)

Examined relationship between cognitive requirements of two chapters of a physics textbook for biology/pre-med students and their ability to use prerequisite reasoning skills required for its understanding. An average of 42 percent of students tested did not consistently use reasoning skills required to understand text concepts. Discusses tests…

The literature on the extent to which knowledge, skills, and attitudes learned in one area transfer to another was reviewed for the purpose of identifying issues that policymakers and providers of vocational education should consider when planning programs to prepare students for further education and life. The review focused on the following…
