Abstract
To investigate the effect of philosophical thinking on the development of reasoning skills and behavioral performance among Iranian primary school students, we conducted a qualitative method study with ten fourth grade students (including boys and girls)selected from different primary schools in Tehran1. We also study the reactions of children and their parents to this new method of education, which thoroughly differs from the method practiced in our schools now. This study was carried out in the Institute for Humanities and Cultural Studies, as an extra class once a week for twenty sessions. Data collection strategies of this study including the authors’ observations during sessions, children’s parents’ observations and reports, and interviews with children and their parents. Our research result shows that reasoning skills enhance communication skills by enabling children to express their ideas more persuasively. We also found that children act more confidently and independently.
