Nine- to 18-month-old infants were presented with simple two-location manual search tasks involving invisible displacements of objects with sequence of displacements occurring before infants search. Results provided insights into age differences associated with development of logical search strategies, information-processing skills, and temporal…

Describes guided discovery and problem-solving programs, providing a buyer's guide for same. The guide includes program name, source, current price, type (such as learning module, simulation, adventure), brief description, and whether the program has graphics and sound effects. (JN)

In a reviewed series of spontaneous and learning-set studies of adults and children, adults solved problems even if they attended to four dimensions; young children failed when attending so broadly, but solved when attending to a single dimension. (Author/HS)

This paper discusses an approach to the study of algorithms which values students' construction of nonstandard algorithms but also emphasizes the essential roles of the teacher and instructional activities in supporting the development of students' numerical reasoning. Episodes are presented from a 3rd grade classroom in which a 9-week teaching…

This paper describes how one group of students came to reason about data while developing statistical understandings related to exploratory data analysis. Episodes taken from a 7th grade classroom in which a 12-week teaching experiment was conducted are presented. One of the goals of the teaching experiment was to investigate ways to support…

Many studies of college chemistry students have found a gap between students' success in solving computational chemistry problems and their success in solving conceptual chemistry problems. This paper examines college students' understanding of the concept of stoichiometry, the particulate nature of matter, and chemistry problem solving. This…

Author intended to illustrate how mathematics could be used as a humanistic enterprise to convey knowledge and attitudes towards the world. (Author/RK)

Shortcomings of management information systems in managerial functions are often attributed to differences between "left brain" activities performed by machines and "right brain" activities performed in decision making. It is argued that academic management information systems should incorporate and recognize both kinds of activity. (MSE)

A simple enumeration problem from some research on problem solving is used to illustrate the contention that conjecture and proof have a central place in mathematics teaching. (Author/TG)

Models of conceptual and language development by Orwell, Piaget, Whorf and Sapir, Vygotsky, and Bruner are reviewed. Their implications for teaching and some individual problem-solving experiments are discussed. (CP)

This discussion concerns itself with difficulties encountered by students in multiplication and concludes that when children understand a problem they can usually solve it. (MP)

Reviews literature on using a problem-solving approach in science instruction. Examines teaching strategies associated with such an approach and discusses a problem-solving approach that works in the traditional laboratory. Discusses implications of the approach and provides some suggestions for science instruction. Contains 17 references. (DDR)
