The problem addressed in this study is the identification of a philosophical paradigm for the Philosophy of Education that is appropriate for accomplishing citizenship education in multicultural contexts. Section one includes a historical overview of the field of Philosophy of Education, designed to identify what philosophers and educators through the ages have identified as the basic goal or purpose of education—citizenship education, that is, the education of individuals prepared to participate and contribute in a meaningful way to their society. Section two includes an overview of the current state and needs of our educational system given its existing and growing multicultural nature, focusing especially on the kind of training teachers need to accomplish citizenship education in a multicultural context. Section three includes a discussion of what Critical Realism is and demonstrates how and why it is an appropriate paradigm for accomplishing citizenship education in multicultural contexts.
