Urgency In Instruction
An engaging, quick-moving classroom comes down to the urgency of the instructor. When the pace is slow and activities feel like a chore, students will effectively 'check out.' Learning is much more likely to happen when the classroom feels important, exciting, and urgent. Use this video and one pager to increase urgency and effectiveness in the classroom.
P.S. As a general rule, take your students' age and divide in half. That's how many minutes you should limit talking/lecture to before moving onto practice or another activity.
