Second Plane - it's a state of mind

Dotressa Maria Montessori proposed that human development starts with four planes. each of the planes is seven years long.

• first plane is conception to 6 years,
• second plane is ages 6-12 years,
• third plane is ages 12-18 years
• fourth plane is ages 18-24 years.

Strangely enough these age groups mirror the Educational Establishments' and Psychologists' conventions of human developmental eras. Could it be that Dotoressa Montessori foreshadowed their thinking, e.g. did Piaget borrow heavily from Montessori? One of the difficulties with Dotoressa's work is the referencing conventions of her period were much less structured and rigorous than those of today. This gives evidence to those academics and "experts" who reject her work because it is documented anecdotally and not 'statistically' validated.

Might, instead, should Dotoressa be recognised as the original Action Researcher? She was in there with the children and the practitioners capturing many of their responses, over a half a century beginning in 1890. There is some photographic evidence, but no lab notes have been made publically available. (Drat!)
