Adults need certain things to happen in order for them to learn something new, and contextualize that knowledge in a useful and accessible place in their long term knowledge. If you want someone to be able to actually use something you teach them in their work, then you have to help them figure out how that new piece of information fits with everything else they already know and do.
There are a lot of ways to encourage this process, but the most important is probably to use the new information right away. Immediately after learning a new skill or idea, learners should practice in some way. Activities, carefully chosen and crafted to maximize information use while minimizing frustration are an important part of any training.
On this page, I am featuring a few of the thousands of activities I have written across the course of my career to give you a sense of what kinds of activities really create training transfer.
