Why My late wife was a Master Teacher

My wife gave me more than 12 years of discoveries, and that is part of why she was a phenomenal teacher. Her students may not have liked everything about her (she was strict) but with her education was a constant discussion. Her way of teaching was to constantly learn. We'd attend conferences and museum presentations, author presentations and seminars; and she'd bring materials back to her classroom from those study venues -- and bring the students to them, when she could, herself. I think of her today as I realize I've learned a lot about learning and education from her. I'm trying to honor her, not just by keeping and sharing what she learned, but by continually learning and sharing what I learn myself. When you stop learning you stop being a master teacher. Long ago I saw that there were three kinds of teachers,

1. ordinary teachers who teach what some other teacher ordered them to teach.
2. Teachers who can teach other teachers.
3. And those who can teach the teachers of teachers.

My Wife was one of the third kind.
