I generally keep an agenda for my training sessions and then make sure that I provide a brief video highlighting each topic.
I provide the teachers with a playlist highlighting the more advanced tools, such as widgets, embedding videos, and inputting a variety of multimedia.
By providing faculty with additional tools and information that may be more challenging, they have the option to accelerate their professional development according to their comfort level and individual needs.
For me, flipped professional development has been highly successful when blended into a more traditional model. I can hold workshops, training sessions and other professional development activities in person with my faculty and continue to support them outside of that face-to-face environment.
Several great tools listed here for teachers to try in their classrooms. Newsela is great for humanities and the Easy BIb Add-On can be used in any class. Several video editing tools as well.
"Easy Bib Bibliography Creator is an add-on that creates a guide within Google docs that allows you to search for books, journals, and websites to automatically generate citations in order to properly format them in MLA, Chicago and APA for a bibliography or a work cited page. (Show this one to your students writing research papers!)"
