This is a great idea. It only takes a minute or two and can give you some VERY valuable feedback on what part of your training may need improvement. Check it out. There is also some PowerPoint resources here that you might also find useful.
Like the two minute paper, the muddiest point technique is best used at the end of a topic–before moving to new material–or at the end of a class session. The exercise asks students to write down one thing about the day’s material that they simply don’t understand. By collecting these, instructors are able to gauge how successfully they taught the material as well as what they may have to revisit before moving on to new territory.
This classroom assessment technique is easy to use and yields powerful results, making it a favorite of instructors in large and small classes. It can be completed in as little as one or two minutes, and it lends itself to every discipline.
To administer the assessment, create a PowerPoint slide at the end of your presentation that asks, “What is the muddiest point in today’s material?” Ask students to respond on paper or note cards. Some instructors ask students for their responses verbally before the end of class, spending the remaining time in the period to answer the questions. Others collect the papers and address the questions via email or at the beginning of the next session.
