The keys to professional learning are always time and self initiation. Initiating the professional learning and investing time are always the first step. One professional learning experience I recently initiated for myself was completing the Apple Teacher Learning Center modules. It was great to be able to learn and relearn things about the Mac, iPad, Keynote, Numbers, Pages, GarageBand, and more. I feel super fortunate to have worked at The Apple Store at both the Stanford Shopping Center and the Palo Alto stores as a Specialist, Theater Manager, and Creative. I learned an incredible amount of information on Apple products, Mac OS, iPods, iPads, iOS, iLife, iWork, Final Cut, iBooks, and more. That experience really helped me go through the Apple Teacher modules with great ease. The content in the modules also really helped me learn new options, structures, and ideas. I highly encourage every teacher to initiate the Apple Teacher modules.
My next self-initiated professional learning will be the Google Certifications.
