TA: Tracking participant progress in a workshop
If you are leading a workshop and the participants are working on laptops, try using sticky notes as a way to gauge where everyone is in the process of completing the assigned task. UCLA teacher Miriam Posner, in A better way to teach technical skills to a group, describes how assigning students to small groups combined with the sticky note strategy serves her students well. This could easily be adapted for work not on computers.
