3. Make your class space as self-service as possible: Take time at the beginning of the year to set the culture that the students can take care of themselves and get what they need for their learning. As students get better (trained) at knowing how to act appropriately in the class space, your teaching is more powerful. You can pay attention to the important things like responding to questions, having deep conversations with individuals or teams, or even giving a short lecture because the students have asked for that information in the Need to Know list.
