When asked if  he ever got bored spending so much time sitting in baseball dugouts during long seasons, the great Yogi Berra said no: “you can observe a lot by just looking.”  The key, of course, is to know what you are looking and listening for and how to recall, record and make use of what you see and hear.  Classroom observation is related to understanding learning and teaching, coaching and supporting colleagues, personal and collaborative professional development, research and assessment.  The ability to accurately observe others – and oneself – is a key professional capability.
