I was having a discussion with a colleague regarding assumptions with candidates knowledge. He brought up a interesting point. (Thanks Jon!)
Too often at a re-certification for First Aid or Lifeguarding, material is reviewed superficially. We state for example, the importance of the Epi-Pen (auto-injector), or rapid aggressive cooling for burns and heat stroke, but don't provide a practical exercise. We assume that everyone knows how to use the auto-injector properly; we assume that rapid aggressive cooling is performed very quickly.
What we get with this approach, is upside down auto-injectors, and candidates overthinking how to cool a burn or heat stroke, when they are standing next to the pool or water fountain.
What does this mean for us instructors?
These are only two examples. There are other skills and knowledge areas that can stand a clear review.
And remember to make sure the candidates feel comfortable asking questions and getting help when needed.
