The confounding of chronological and educational age and of schooling and socioeconomic status are persistent problems in the study of the cognitive consequences of schooling. The educational system among the Kharwar in India provides a natural experiment to overcome these problems, since it shows neither source of confounding. The sample…

This paper explicates a pattern of scientific argumentation in which scientists respond to causal questions with the generation and test of alternative hypotheses through cycles of hypothetico-predictive argumentation. Hypothetico-predictive arguments are employed to test causal claims that exist on at least two levels (designated stage 4 in which…

This study investigated the contributions of students' reasoning ability and meaningful learning orientation to their understanding of the photosynthesis and respiration in plants concepts. Data were gathered through the use of the Test of Logical Thinking (Tobin & Capie, 1981), the Learning Approach Questionnaire (Cavallo, 1996), and the Two-Tier…

Empirical evidence of no age-related decline in life satisfaction (LS) in old age contrasts with frequently observed declines in the objective quality of elder people's lives and has therefore been labelled a "paradox" and interpreted in terms of stability of LS in the respective gerontological discussion. However, as this evidence was…

This study aimed to identify the types of arguments promoted in various contexts common to a high school chemistry classroom, including lecture-discussion and laboratory activities. The study was guided by the following research question: What types of argument structures and schemes, if any, are promoted and engaged by students within various…

The purpose of this study was to determine the influence of an STS curriculum (ChemCom) versus a traditional chemistry curriculum (GenChem) on student formal reasoning level. Cluster random sampling was used to select the sample (N=123). Gender differences in formal reasoning level were also investigated. The abbreviated GALT pretest was…
