This commentary highlights important contributions of four empirical investigations of how people sort through the masses of information that are now available to them and find what they need to solve some problem or make some decision. These studies demonstrate the impact of differences among information sources and the role that these…

In his 1979 "Human Development" article reprinted in this anniversary issue, James Wertsch presented an approach to genetic analysis of the shifting regulation of problem-solving behavior in early childhood. In my reflections on Wertsch's seminal contribution, I discuss ways that subsequent inquiry built upon ideas he elaborated in the…

Effective problem solving depends on adopting the appropriate frame of reference to guide the search for solutions. If the problem is mislabeled or the wrong frame of reference used, the chances for success are lower. (SK)

This paper examines to show how an investigative approach to mathematics teaching can honor its two important dimensions--a thinking and reasoning side to go with the skill development. The paper addresses the question of why a problem solving approach has failed, makes the case for investigations as an overarching organizer, and discusses the…

Examines the processes of science focusing on the higher-order skills and the role that relevance may play in their acquisition. Argues that an open inquiry style of instruction appears best suited to stimulating the learning of process skills because it allows students to pursue problems of genuine relevance. Contains 26 references. (JRH)

Discusses the inherent flaws in considering and using the epistemology of the natural sciences as equivalent to a pedagogic basis for teaching and learning in the natural sciences. Discusses the difference between practicing science and learning to practice science. Concludes with the presentation of three new motives for the use of laboratory…

The narrative structure of a classroom event describes the order in which the story of the event unfolds. This paper compares the narrative structure of a traditional classroom to that of a communicative classroom. The comparison is made in the form of a drama in which a communicative mathematics spokesperson relates the comparative mathematics…

Proposes that problem scenarios are activities that give students opportunities to employ mathematics across the curriculum by asking them to define problems, identify information needed and potential sources of data, and make related conjectures. Discusses an example of a scenario involving transportation. (MDH)
