The Evolution of Proportional Structures in Children with and without Learning Differences.
Peer reviewed Peer reviewed
Grobecker, Betsey – Learning Disability Quarterly, 1999
Twenty-nine children with learning disabilities (LD) in grades 2 and 4 through 7 were compared with children without LD for their development of proportional structures of thought. Significantly fewer children with LD had constructed second-order logical structures necessary to act on problems using multiplicative and preproportional reasoning.…

A Neurological Model of Sensory-Motor Problem Solving with Possible Implications for Higher-Order Cognition and Instruction.
Peer reviewed Peer reviewed
Lawson, Anton E. – Journal of Research in Science Teaching, 1986
Reviews the neural modeling principles of learning, perception, cognition, and motor control, discusses their applications to sensory-motor problem solving, and explores possible relationships between that pattern of problem solving and aspects of higher order formal operational problem solving. Cites implications for science education. (ML)

Student Gain in Reasoning Ability as a Function of Teacher Reasoning Level and Teaching Style Preference.
Peer reviewed Peer reviewed
Lawrenz, Frances; Lawson, Anton E. – Journal of Research in Science Teaching, 1986
Presents study findings which explored the effect of teacher reasoning level and teaching style preference on improvement in student-reasoning ability. Reports that students of concrete operational teachers and of inquiry teachers showed greater gains in reasoning ability than students of formal operational teachers and of expository teachers. (ML)

Conflict and Social Marking in the Acquisition of Operational Thinking.
Peer reviewed Peer reviewed
Doise, Willem; Hanselmann, Claude – Learning and Instruction, 1991
To illustrate the joint intervention of sociocognitive conflict and social marking in cognitive processes, 160 children (87 males and 73 females) in Geneva (Switzerland), with an average age of 6.5 years completed conservation of number and conservation of liquids tasks. Conflict and social marking are important in the acquisition of operational…

Intellectual Development, Science Anxiety, and Content Achievement in Preservice Elementary Teachers.
Hall, Donald A.; And Others – 1989
This study investigated preservice elementary teacher reasoning ability levels, science anxiety levels, and content achievement in a large midwestern university. Pretest and posttest measures were taken on three dependent variables: (1) reasoning ability (cognitive development); (2) science anxiety; and (3) science content achievement. In…

The Effects of Free Exploration from Hands-On Science Center Exhibits.
PDF on ERIC Download full text
Boram, Robert; Marek, Edmund A. – 1991
The purpose of a study was to explore the link between conceptual understanding, free exploration of hands-on science center exhibits, and Piagetian cognitive developmental levels. In this primarily qualitative study, which is based upon interview and observational data, patterns in children's behavior relating to specific hands-on science center…
