Stephen Hicks, a highly productive super-teacher, links to 2 good articles I liked.
One is by Kathy Sierra, on putting the Muse on deadline. (Worth it for the opening visual alone.)
I admit my muse is unruly,
And sometimes treats me coolly.
The other is by my wife, on the qualities of a great teacher.
As usual, her story
Includes quotes from Montessori.
