Glossary of Montessori Terms Haines, Annette M. The Montessori approach, much like any science, has its own set of vocabulary and terminology. Montessorians share a very specific set of brief references that evoke the world of the child as described by Maria Montessori.. The Glossary of Montessori Terms relates to the theory and practice for the Primary (3-6) level. It was prepared by the late Annette Haines (Montessori Training Centre of St. Louis) at the request of Molly O'Shaughnessy (Montessori Centre of Minnesota) to accompany her lecture at the Joint Annual Refresher Course, held in Tampa, Florida in February 2001.
