Teacher.net is hosting a live chat with me on Sunday, February 4 at 4 pm EST. I'm excited, especially since the request came from a spirited discussion on their site about the true meaning of rigor. There are so many different perspectives of rigor, many of them negative. My definition of rigor is creating an environment in which each student is expected to learn at high levels, each student is supported so he or she can learn at high levels, and each student demonstrates learning at high levels. It's really all about helping students learn. Isn't that why you became a teacher?
