Pear Deck provides a Lock button and a Lock Slide Timer to help you control the pacing of Instructor-Led lessons. Clicking the Lock button once immediately locks student screens so students cannot change their answers. Holding the Lock button lets you set a countdown timer before screens lock automatically. Use these controls to keep students focused on Projector View, prevent distraction from Drawing and Draggable tools, and stop answer changes after you display responses.
