The more I get involved in Professional Development (PD) I have had to determine how to approach developing my content and how to approach delivering my workshops. My experiences attending PD's in the past contributed the development of my approach. Show and Tell is how best I can described my approach to the PD's sessions I present.
My PD sessions have focused on Google Apps For Education (GAFE) and as an avid user, developing and presenting on this topic has come easy. As a teacher I feel it is best to show how I use GAFE and the features of the available tools. I think it is best for teachers to actually see how other teachers are using GAFE rather than just learning about the different features. Using this approach has worked positively.
When I develop my content I try to use the tools I am presenting about. I have stayed away from PowerPoint and solely use Google Slides. My slide shows contain some theory, screen shots, videos, and additional resources. All of which I actually use. Throughout my presentation I bounce back and forth between my slide show and the topic I am presenting about. For example, I would show teachers my actually Google Classroom.
One standard phrase I say to participants when I begin my sessions is, "I'll show you the features, show you how it works, show you how I use it, and advise you to "play" with it to determine how best it may work for you." This thought process has been welcomed by participants.
Additionally, I feel it is important to receive questions from the participants. This opens up the session and even raises questions or offers suggestions I may not have thought about. Especially when dealing with GAFE and the multitude of uses possible.
To conclude. My approach to PD is to share my experiences with participants in a live fashion. I find it important to show how I use these tools and how it may be used by others.
