SC Midlands Summit. It was a great two days of learning. I attended sessions about learning Chromebook ninja skills, how to use Picasa in the classroom, using photographs for visual storytelling and the programming language Scratch.
Starting next week, I am going to begin three PBS Teacherline courses. I highly recommend PBS Teacherline courses for professional development. It's not free, but definitely worth the investment. So far, I have completed three online classes and always learn information & skills that I apply to my practice. I've never taken three online courses at one time, so I may be MIA for a bit as I try to juggle online work & family life.
Along with reading blogs, Twitter and Facebook, I like to watch webinars to help me with my practice. I usually sign up for email reminders and catch an archived webinar when I have a moment. For example, this summer I want to learn about Common Core & flipped classrooms because those will be hot topics in my school this coming fall. I'm going to watch a few webinars to help me get started.
Here's a list of sources for free online webinars:
The Future of Education
TL Virtual Cafe
School Library Journal
Where do you go for professional development?
