During Mother Goose on the Loose programs, the facilitator models the use of positive reinforcement when children are asked to do a specific task and they successfully complete it.
I had my own wonderful dose of positive reinforcement this weekend: I returned from a workshop in San Francsico and received an email from one of the participants that read:
I attended the training you did at the SFPL on Monday, September 27th, and it was great. You make me want to be a better librarian.
What inspiring positive reinforcement that was for me!
