ABSTRACT
This chapter focuses on how formal education – developed mainly in schools, colleges and universities – incorporates learning by teaching into its practices, increasingly and deliberately: activities that embody the principle of learning by teaching, in an implicit or explicit way. These activities offer opportunities for students to learn by teaching their peers. The chapter refers to the conceptual changes that are taking place in these formal contexts which support this type of initiative. It presents examples of formal education practices containing the principle of learning by teaching. Social changes have generated huge amounts of pressure in educational systems, challenging them to respond to the new needs that the times demand of them. Although traditionally classrooms and schools were organized around the individual and competitive learning, today teachers know that offering opportunities to students to cooperate and work together is absolutely necessary, for several reasons.
