We explored the mediating role of prior knowledge on the relation between intelligence and learning proportional reasoning. What students gain from formal instruction may depend on their intelligence, as well as on prior encounters with proportional concepts. We investigated whether a basic curriculum unit on the concept of density promoted…

Dual Process Theory has recently been applied to Autism spectrum disorder (ASD) to suggest that reasoning by people with ASD and people with higher levels of ASD-like traits can be characterised by reduced intuitive and greater reflective processing. 26 adolescents and adults with ASD and 22 adolescent and adult controls completed an assessment of…

This study examined whether familiarity with content influences performance on conditional reasoning problems of the form P implies Q independently of ease of generation of specific examples of "Q and not-P." Results indicated that increased content familiarity resulted in higher performance levels. (Author/JAZ)

The logical foundations of deduction and induction are outlined to form the rules for the construction of a set of tests of reasoning ability. Both deduction and induction involve the derivation of a conclusion from a set of premises. Deductive logic uses syllogisms and is abstract. Inductive logic is both empirical and abstract. Although…

Students and instructors may be frustrated with students' lack of understanding of sociological concepts. We suggest that the difficulty of teaching and learning sociology is that sociological concepts and relationships require the use of abstract reasoning patterns. Many students are unaccustomed to using these abstract reasoning patterns. We use…

Recently, a number of studies have reported a high correlation between the supposedly separate traits described as integrated science process skills and formal reasoning ability. The implication has been that these two constructs are different but related. Further implications have been made that a treatment to enhance one "trait" might…

Lawson's test was used with 66 ninth grade and 63 tenth grade students. Results show: that boys outperformed girls; a small correlation between achievement in science and mathematics and the Lawson test; and that Israeli students achieved significantly higher than United States students on the Piagetian skills measured by the test.

Piaget has hypothesized that concrete and formal operations can be described by specific logical models. The present study focused on assessing various aspects of four concrete operational groupings and two variations of two formal operational characteristics. Six hundred twenty-two 9-14 year old students participating in the Human Sciences…

The Inductive Reasoning and Analytical Reasoning tests of the Johnson O'Connor Research Foundation have been analyzed in a factorial study including marker tests for two commonly recognized reasoning factors, induction (three tests) and logical reasoning (two tests). The primary purpose of the study was to determine the extent to which the Johnson…

Preservice elementary teachers' use of examples in recognizing and disproving invalid deductive arguments related to topics in elementary school mathematics was examined. Two forms of the Classroom Logic Test were developed, one multiple choice and one free response. Subjects were asked to judge the correctness of arguments and, if incorrect,…

This study investigated the development of students' abilities to integrate information in stories as an aspect of reading comprehension. Students aged 8, 11, 14, and 18 judged the importance of key statements, which varied in their causal relations within an episode, between episodes, and in a higher-order structure, yielding three levels of…

In Piaget's developmental psychology the fourth and highest stage of human cognitive development is that of formal operations. The research on formal thought instruments is outlined. This study was designed to construct and validate paper-and-pencil instruments which could be used to select students capable of abstract conceptualization,…

This educational research project is designed to assess an elementary student's quality of reasoning in relation to map skills and to determine spatial concept abilities. 21 activities are designed to test sense of proportion, scale, dimension, accurate relationship, and abstract thinking. The related topographical map, a Map-Study Scoring Key,…

A set of eight widely used inductive reasoning tests were investigated to determine whether or not they have different factorial structures. The eight inductive tests and three deductive tests, taken from the French Kit of Reference Tests for Cognitive Factors and the Watson-Glaser Critical Thinking Appraisal, were administered to 157 high school…

The purpose of this study was to investigate the relationship between the achievement of some abstract concepts in "molecular genetics" and prior knowledge, formal reasoning ability, and sex. The major findings of the study were: (1) prior knowledge had a high significant correlation with the achievement of abstract concepts; (2) the…
