Discussed are some situations students face that result in cognitive conflict, possible sources of these conflicts, and strategies which students use to resolve, remove, or circumvent them. A global account for observed systematic errors is offered based on a general problem-solving rule called the "Matching Rule." (KR)

Analysis of the relative contribution of age, gender, and verbal and mathematical reasoning abilities (measured by subtests of the Scholastic Aptitude Test) as predictors of success in accelerated secondary science courses found that a composite of verbal and mathematical reasoning ability was the most powerful predictor and verbal reasoning…

A teaching experiment with six third graders to analyze their ways of operating while solving fraction tasks. Children's quantitative reasoning with fractions was based on their quantitative reasoning with natural numbers. Presents the constructive itinerary of one of the most advanced children in the group. (Contains 44 references.) (Author/MDH)

Reports a study of 913 Israeli students in grades 7-12 from randomly chosen heterogeneous homeroom classes to investigate students' Piagetian cognitive levels using a video-based test. Results indicate that less than 50 percent of high school students have mastered formal operational reasoning. (MDH)

Identifies the types of reasoning involved in middle grade mathematics with regard to multiplicative structures and the difficulties students have with the concepts, why these difficulties might occur, and the interconnections within this content area. Offers four recommendations for the preparation and professional development of teachers.…

Examines two theoretical approaches on how we understand our own and others' minds: a causal explanatory and an interpretive social approach. Explores the relations between these views and suggests that the real challenge of the cognitive revolution is to unite the two approaches, to achieve a causal naturalistic account of the acquisition and…

Suggests that a better understanding of the development of children's theories of mind, requires theoretical perspectives that do not privilege the child who conceptualizes or actively participates in social interactions. Proposes that a better understanding of the relationships among brain, psyche, behavior, and culture should be promoted. (AA)

Examines Astington and Olson's proposal under the context of von Wright's and Hempel's theories of explanation and understanding. Suggests that for taking children's meaning making seriously, researchers should find a principled way to acknowledge the role of interpretation in scientific thinking even in the making of explanation itself. (AA)

Examines the relationship between causal-explanatory and interpretive-hermeneutic approaches to how we understand our own and others' minds. Suggests that the two approaches discussed by Astington and Olson are mutually enlightening but, contrary to the proposed position, are irreducible to each other. (AA)

Points out agreement that the concepts a child acquires are variants of those exemplified by the cultures in which they grow up. Suggests, however, that learners interpret these cultural practices in terms of models causally determined by their cognitive or representational capacities and by the stock of concepts currently available. (AA)

In this paper I focus on the transition from everyday to scientific ways of reasoning, and on the intertwined roles of meaning-making dialogue and science content as they contribute to scientific literacy. I refer to views of science, and how scientific understanding is advanced dialogically, by Hurd (Science Education, 1998, 82, 402-416), Brown…

Teachers tend to design worksheets to assist their students to develop their spatial skills. Many secondary schools students may not have sufficient concrete experiences to tackle abstract reasoning in geometrical concepts competently. In addition, students who are non-visual and spatial learners may have difficulties in learning geometrical…

In a multiple baseline design, a teenager with a mental age of four years was taught two abstractions. One was the oddity principle (selecting the one object in a group which differs from the rest). The other was seriation (aligning objects along a continuum of size, and inserting new objects into their proper places in the alignments). These…

This article offers a skeletal critique of the pedagogical theory and the teaching practices arising from the work of educational innovator, Benjamin Bloom. Professor Bloom's theory and method have overtly and covertly insinuated themselves into North American educational practice over the past half-century. Their impact and influence have been…

This exploratory study had two goals: (1) to identify signs of abstraction and consolidation of abstractions of functional concepts in students in a situation-based curriculum; and (2) to use theoretical arguments as well as experimental evidence in order to shape notions of abstraction and consolidation of abstractions. The methodology was…
