E. M. Standing’s observations are part biography and part exposition of Montessori’s ideas and philosophy. As a collaborator and friend of Montessori, his perspective addresses both her revolutionary breakthroughs and the difficulties in implementing the Montessori method. Required reading in most Montessori teacher training programs, this book is a thorough, systematic, and eloquent presentation of her principles, with a large sampling of anecdotes. Paperback, 380 pages.
