Susan Mayclin Stephenson first began explaining Montessori in 1971, through a school newsletter that helped families of her students understand the essence of Montessori. She has continued to write and speak, based on personal experience, since that time.
Here is a quote from the upcoming book on observation and record keeping for the primary and elementary class, Please Help Me Do It Myself:
Rather than focusing first of all on the academic work in class, when I had a meeting with parents, I showed the parents the concentration graphs for their child. This kept the focus on the value of their child learning to independently choose work, to experience deeper and longer periods of concentration, and the positive results of this experience.
I found that this was an excellent way for parents not only to begin to understand Montessori, but to look for, and hesitate to interrupt, their child’s concentration at home.
