Analysis of the Development of Propositional Reasoning. Final Report.
Falmagne, Rachel Joffe; And Others
This document focuses on a series of studies that viewed aspects of conditional reasoning. The investigations were concerned with the processes children use to acquire patterns of deductive inference and logical relationships pertaining to propositional reasoning. The first experiment, involving 96 children each in grades 2 and 5, investigated the ability of children to construct a formal representation of a Modus Tollens inference. A follow-up experiment and a pilot study dealing with acquisition of patterns of deductive inference are also discussed in the first of the document's three major sections. Section two focuses on effects of content on reasoning, with three experiments described. The last major section of the report looks at an experiment in geometry instruction that involved two phases, one devoted to teaching deductive reasoning processes and one concerning direct instruction in formal geometry. The document ends with concluding remarks reviewing implications of all the research noted. (MP)
