The average attention span is 2-3 times a student's age. So with that in mind, how do you keep them from losing focus in a 90-minute class? This episode is all about how to use brain breaks and other strategies for maintaining focus. We start the episode discussing how long our classes are, and in the case of longer periods, why it is necessary to take breaks if you want students to stay productive, and why it's unrealistic to expect someone to be attentive for the duration of a class. We talk about the need for "predictable variety" as a way to keep students on their toes (9:00), before actually going over some brain breaks, which serve as "palette cleansers for the brain" (14:00). Then we discuss how to keep variety in the classroom even without breaks that go off topic (23:15). Joseph gives a funny story from coaching soccer, and then we play the Numbers Game with an incredibly close finish.
