1. Dr. Grant Wiggins - UbD is everywhere. It is the basis for most lesson plans now.
2. Dr. Carol Ann Tomlinson - differentiation. Enough said.
3. Vygotsky - I love his work with zone of proximal development.
Dr. Wiggins was only 64 and seemed like he was still going strong. Kinda makes me want to push myself harder and not put my life's goals on the slow track. Dr. Wiggins had a great blog and loved to debate and ask questions. I will really miss him.
