There is little benefit in training if your clients fail to successfully apply the ideas you present. You must be a motivator as well an instructor or coach.
Recently, while training a group of visitor service staff members at a museum, we spent time focusing on their past experiences with evaluation. Each of them was about to begin conducting intercept interviews of visitors and they needed to feel comfortable. So, I gave each of them an opportunity to highlight their past, focusing on any experience they had with evaluation. Though their examples were sometimes tangential at best: working with a Social Psychology professor tallying survey results,; completing course evaluations; conducting pre school student assessments; completing retail and restaurant comment cards, they came to realize they could do this. If they embraced the process it would be a notch in their professional development belt. What were we doing? Digging into their past to inform the present. Involving them wholeheartedly to make them part of the process, inserting their energy & life experience...Motivating them by letting them realize that evaluation is not scary, but empowering. Though it has to be based on goals and objectives, it doesn't have to be intimidating, theoretical, or forced. It is practical, useful, common sense, and yes, sometimes even fun!
