Treating Estimation and Mental Computation as Situated Mathematical Processes.
Silver, Edward A.
This paper discusses the central thesis that new research on estimation and mental computation will benefit from more focused attention on the situations in which they are used. In the first section of the paper, a brief discussion of cognitive theory, with special attention to the emerging notion of situated cognition is presented. Three sources of expertise as contextual are proposed: social theories about language and the development of thought; anthropology and the study of situated cognition; and the history and philosophy of scientific domains. In the second section, "Mathematics and Sense Making", a review of work on problem solving that dealt with the importance of context, especially with respect to the interpretation of problem solutions is presented. Situational factors that influence children's problem-solving performance are described though research findings on division with remainders in problem-solving situations. Finally, a situated perspective on further research regarding serious consideraiton of mental computation and estimation as situated mathematical processes is discussed.
