The mind is not a vessel to be filled, but a fire to be ignited

is one of my favorite quotes by Plutarch. Here is a view from my first exercise-book. On the right page I tried to erase an error that was awarded a small devil (in Oct 1964 by my teacher at Drais Realschule in Karlsruhe).
Things have changed when looking now at the exercise books of my children although basic principles remained the same. While I see a lot of advantages of Montessori and Waldorf schools, I have doubts if the longterm outcome is really as good as believed. PISA doesn´t breakdown by school type – maybe if would be even better to look at personal happiness, yea, yea.
