A few months after I started using iPads in my classroom, I found this excellent resource from Rising Stars.
The educational publishing company have recently branched into providing online CPD courses, and the iPad module is a free taster. Completing the course led to a real shift in my thinking, and made me feel better-equipped for leading our school forward in our use of iPads. Registration was simple, and progress through the module was saved so I could come back to it when I had some spare time.
Worth a look!
