If you are teaching a group of people here's a useful technique: "I do, we do, you do".
I do the task once, then the entire class does it together (in lock-step fashion), and then everyone does one on their own.
When I do it, it gives everyone an understanding about how it is supposed to work from beginning to end.
When we all do it together, we have the benefit of knowing what is supposed to happen and fully understand the end point, but we are learning the individual steps and experiencing them in a safe environment since everyone is doing the exact same steps and waiting for everyone to finish step n before moving to step n+1. If someone is having trouble, other classmates can help them (which is educational in itself).
Lastly we do it individually. We know how it is supposed to be done, the training wheels are off, and we learn to do the task independently.
You can use this when teaching a fellow coworker one-on-one. Do the task yourself. Do the task as they do it too, mirroring your actions. Then let them do it on their own.
[I bring this up because I remember all the times that people have tried to each me something without the "I do" step and I don't even know why I'm doing what I'm doing. If they had showed me what we were trying to do in the first place, I would have learned faster.]
