This exercise is especially useful for trainings that span several days. It
- allows participants to reflect on their personal learning highlights,
- lets them share their insights,
- provides regular feedback to the trainer about what parts of the material gets the trainees attention and how they interprete it, and
- organically and collaboratively lets an artifact emerge that will remind participants of their main lessons from the training.
How it works:
This is my take on how to execute this exercise. While I think that it's close in spirit to what Alistair does, there are probably also many details mentioned below that are more rooted in my personal experiences and values than in observing Alistair facilitate this exercise.
First round of gathering aha-experiences (15 min.)
Start with the exercise early in the training. A good point in time is when you covered enough material for the participants to have aha-experiences to report, but early enough that it still feels like the start of the training. Typically that will be after the first one or two lessons/exercises, not more than two hours into the training.
Hand out a block of sticky notes (extra-sticky, if possible) and a marker to every attendee. Ask them to take a few minutes to think about and write down two aha-experiences, each on its own sticky note. An aha-experience could be something that surprised them, something that got their attention, or simply something they want to make sure to remember. (It's often not too hard to come up with one aha-experience, but having to come up with a second might require some deeper digging. See it as a challenge that your trainees might need some gentle support for, in contrast to a requirement that needs to be enforced.)
When they finished writing, go around the room and ask every participant to quickly read his/her aha-experiences aloud. Thank everyone for the contribution. Don't allow discussions at this point - the goal is to just get a sense of what the group has learned until now. Don't critizise a "wrong" aha-experience, as you don't want your trainees to censor themselfes out of fear of being publicly critized. Take it as valuable feedback that you can use to adjust coming parts of the training.
After the last participant presented his/her aha-experiences, ask them to stick their notes to a wall that you reserved for this purpose. It should provide lots of space for adding more notes later during the training, and should be easily visible for the attendees throughout the training (that is, a wall in their back isn't a good choice). A front of windows works well, too.
Finally, tell participants to keep looking for aha-experiences for the rest of the training. Whenever they have one, they should immediately write it down on a note and stick it to the wall.
Keep it flowing
If you are lucky, your trainees will happily accept the invitation and continue posting aha-experiences to the wall. Just make sure that sticky notes and markers are always easily accessible. Make it your morning ritual to check all tables and replenish supplies where necessary.
Depending on the group and the room layout, you might need to gently remember the group to continue posting aha-experiences and to look at what others have written. You might even want to schedule short slices of time just for reflecting on the training and writing sticky notes. Five minutes just before lunch break have worked well for a group that otherwise wouldn't write down any aha-experiences.
Debriefing (20 min.)
As part of the debriefing for your training, give participants one last explicit chance to stick more aha-experiences to the wall.
Then let the group gather in front of the wall (you might need to make some room), and group duplicates. Everyone should look at the posted notes put together those that seem to say the same thing. If the text actually is different, it helps if they are both still readable. Encourage discussions; if the author of a note argues that it is different from another note, that should be respected and the notes not be considered duplicates.
When things settle down, hand out sticky dots. Ask participants to put a dot on every aha-experience that's important to them personally. Every participant can use as many dots as s/he wants, one dot per aha-experience.
When dots have been alloted, read aloud one to two handful of top-voted aha-experiences. Depending on the number of sticky notes and the obviousness of the distribution of dots, you might want to sort the notes by number of dots, first.
Let the group discuss observations: are there any surprises? Is there something missing? Have there been important learnings that didn't manifest in aha-experiences?
Finally, take one or more photos of the notes on the wall (the notes should be easy to read on the photos) and provide them to the participants as part of the training documentation.
I like the way this exercise continuously involves the participants in the training and puts a focus on their individual and collective learning. I will definitely use it again in the future for trainings that span more than a day. I wonder how well it would work for shorter trainings, or how it might need to be adjusted.
If you try this exercise or variations of it, please let me know what you learn!
