In a very small class - 3 students, PRU setting, a student sat with his head on the desk during a Lesson Ob. Wouldn't engage at all. Wouldnt even talk to me or the Head who was observing. Eventually he left the class. Any thoughts on what I could have done? I got a Needs to Improve. SLT were only able to suggest one idea of 'do a group activity' to try and engage another time. Im concerned, what if it happens again in a lesson obs ?
