He received his Ph.D. in 1989. His research focuses on adolescent development in the family and the role of interest in education and lifelong learning. Prior to this research study, Dr. Rathunde’s only experience with Montessori education was his eldest daughter’s one day a week preschool experience in a program with a Montessori approach 16 years ago. He is not a member of the Montessori community. David Kahn, a prominent Montessorian, asked Kevin Rathunde to take on this project.
