Learning is important to me. Thinking about the various aspects of assessment that get at concepts has been important to me. It is amazing to me that one performance assessment activity can test so many concepts. This work has affected my teaching in thoughtful and positive ways: I want to add more “play” and “discovery” time into units, thoughtfully embed more time and strategies into my instruction in those areas where conceptual understanding is lacking, and include more assessments in my classroom in the future. Pre and post testing, as well as treatments prior to post testing, satisfies a need I have to use information to assess my teaching and students learning. My work with AIS causes me to rethink my teaching, and for this I am grateful. The practitioners meetings with interesting people who have powerful ideas about teaching, learning, and how to assess them has been great! I love being surrounded by thoughtful people who force me to think.
