Providing feedback can help by reinforcing the bits of the skill that the learner performed as per the demonstration and providing a maximum of three key points they need to focus on again.
评价反馈能帮助学员强化技能要点,可以针对他们的演示,最多提出三个他们下次需要注意的关键点。
The critical point here is that three is plenty. Otherwise you run the risk of overloading the learner. However, before you give the feedback, ask yourself whether they need it, or do they just need another go?
There are times when we need to be clear and our instructions to be direct. Where safety is concerned, for example, we ‘tell’ – we are didactic in our delivery style. Another time we are direct is when students are new to the techniques and we have to tell them what to do to perform them.
