The practical element of classroom observation focuses on what is observable - what the teacher and students are saying, making, doing, and writing. Professor Richard Elmore (Harvard University) developed an ‘open observation method’ where observers describe what they see and hear in the classroom in the first instance. Second and third order questions provide a greater focus on the students in classroom - the nature of academic work and the conditions of learning (pages 64-65 of Looking at Classroom Practice).
