When you join a club or an organization, do you only learn when you are doing your part?
That’s a trick question. What, exactly, IS your part?
Starting with the basics:
Timer: What kind of Speaking Skills or Leadership skills do you improve as a timer?
Grammarian: How can being a grammarian be used to further your skills and help you reach your goals?
Evaluators: What kind of awareness can you build in observing evaluations? How do you use those observations to help you give better evaluations? How do evaluations impact your speaking and leading abilities?
Table Topics: How many skills do you employ to be a good table topics master? What kind of skills are you improving as a table topics speaker?
General Evaluator: When would you use this particular role outside of Toastmasters? How many skills does it involve?
Toastmaster: How can you make use of the toastmaster skillset outside of Toastmasters? Can you use these skills when you are NOT in charge of a meeting? Can you lead from the audience?
Speaker: Which role would you consider the best training for a new speaker? How would you improve your speaking skills using the roles of evaluator, timer, and grammarian?
The WHOLE MEETING teaches you what you want to learn, not just your small part in it. There are no throwaway roles in a meeting, just as there are no throwaway offices in the club.
