Many teachers who begin to implement the Project Approach are already familiar with a learning center or theme approach to teaching, but there are some important differences of which to be aware. Noting that projects are especially valuable for children in undertaking in-depth study of real-world topics, this paper presents the reflections of several teachers on their experiences moving from the use of a theme approach in their classrooms to using the Project Approach. The paper is presented in two parts. The first part describes how a project on shoes undertaken by a kindergarten class might unfold, based on a synthesis of several teachers' accounts of how they proceeded with such a project. The description serves as an example of the potential of a project for the in-depth study of a topic. The second part of the paper is a commentary, interwoven with the narrative description of the project, and draws on the work of different teachers who have also carried out projects on the topic of shoes. This commentary, which features the different possibilities that may occur for teachers in different locations and working with different ages of children, also discusses a few of the challenges commonly experienced by teachers beginning to do projects, particularly the distinctions between projects and themes.
