Muddiest Point Crowdsourcing

Following the model of a minute paper, Sheila Tobias developed a muddiest point write-to-learn activity in which students write a question or a few sentences seeking clarification from the professor, perhaps on index cards. Instructors then read through the stack and figure out what topics they should revisit in the next lecture based on trends.

This peer feedback task turns muddiest point writing into a crowdsourcing activity where students can either vote up questions they too want the professor to answer or answer the question themselves. It encourages students to recognize that others too have questions (perhaps better ones than theirs), and it allows students a chance to help each other before the instructor intervenes.

This assignment sequence requires very little set-up and can be used in any discipline.

Here’s the full text of the writing task:
