Revisits the basics of Piaget's theory, a psychological theory of intellectual development. Discusses Piaget's theory from the perspective of learning science, especially chemistry. (ASK)

Investigates whether introductory college chemistry students today differ from those a generation ago in terms of Piagetian cognitive functioning, aptitude, and achievement, and whether the gender differences in Piagetian cognitive development functioning found in 1981 are still evident today. Suggests that today's students are different in a…

Discusses the goals of learning cycle laboratories in helping students acquire knowledge about a specific topic and to do so moving in a non-threatening way from the concrete operational level to the formal operational level. Describes an experiment designed for such laboratories dealing with the topic of oxidation-reduction. (TW)

Reports on a study intended to establish a relationship between the M-space (mental energy) and the M-demand (the variable difficulties of Piagetian tasks presumed to entail the same logical structure) of different items of general chemistry. Recommends that chemistry teachers consider the role of cognitive factors in determining student success.…

Describes the application of the Piaget-based learning cycle technique for teaching an introductory organic chemistry course. Explains the step-by-step process used to convert a lecture course into a discussion-based active learning course. A learning cycle provides students with concrete material and aids them in understanding abstract concepts…

Describes a study which was designed to determine the effect of a 25-hour introductory qualitative analysis course on high school students' understanding of formal concepts related to electrolytes. Suggests that introductory concrete experiences better prepare students to deal with more formal abstract concepts. (TW)

Defines M-demand as the maximum number of schemes that the subject must activate simultaneously in the course of executing a task. Discusses the effect of M-demand on problem solving. Uses algorithms to reduce M-demand. Describes the role of algorithms in problem solving. (MVL)

Outlines the constructivist model of knowledge and describes how this model relates to Piaget's theory of intellectual development. Contrasts the constructivist model with the traditional views of knowledge. Discusses how this model can help explain some of the things that happen in chemistry classrooms. (TW)
