Philosophy for Children, a thinking programme, has been initiated in a few primary and secondary schools in Singapore since January 1992. The programme aims to foster and strengthen critical thinking among the students in these schools. It endeavours to improve students' thinking through the discussion of philosophical issues embedded in novels specially written by Matthew Lipman, the founder of the programme. The teacher generates discussion usually by suggesting an issue to discuss about the passage. Children are encouraged to discuss, listen, clarify and justify their thinking. Experiences in the Singapore project, so far, have indicated that Philosophy for Children has added a new dimension to the ways the students approach thinking. This paper presents the experiences of the programme and the feedback from teachers and students on the programme.
