other teachers. Although I am new to this profession, I have heard maybe 8 - 10 speakers at PD days lecture and speak on the art and science of teaching. My peers, judging from their comments, mostly tend to shrug off what they have to say and go back to what works best for them.I too wonder about their credentials (although all of them claim to be former teachers) - it's a big difference between teaching adults in 4 -8 hour stints vs. being in a class with 20 - 30 young people for an entire year. I also assume it may be a bit easier at the end of the day but i tend to be skeptical by nature. For you with more experience, when you attend a PD day and listen to a speaker, how do you differentiate the wheat from the chaff so to speak (or as we used to say, the flycrap from the pepper)? This may be an odd question but it's one I have reflected on after every PD day. Interested in any thoughts or comments you may have on this topic.
