Reading can be an essential part of your training and a pitfall you will want to avoid.
First the positive:
As long as people are reading they cannot be daydreaming (at least some of the time). Using the Scavenger Hunt strategy where teams of participants try to find essential information in a bland policy document can be a fun way for them to learn and promote healthy competition.
Now the negatives:
Instructors who read to participants are inviting daydreams to the nearest Lotto winning fantasy. (Remember, the first time anyone read to you was to put you to sleep). Many of them will be able to read to themselves faster than you can read to them, and some will find you reading what they can read irritating.
Asking participants to read out loud is another strategy to be avoided. Some people may not read very well nor comprehend what they read as well as others. This can be extremely embarrassing and increase tension in the class.
What to do:
Allow your class to read to themselves through a hand-out, transparency or slide. Groups of 5 work well and allow the slow reader to blend in with the better readers and still contribute to the exercise.
To read or not to read—this is the answer.
