You'll know I'm an Apple advocate; laptop, phone and iPad.  But when schools work with Chromebooks you have to be open minded or become a relic.  I just love iMovie but it doesn't love Chromebooks so I decided to give this wee programme a decent chance.  And I'm more than happy I did.  I even got a certificate and this crazy badge to show how smart I was.  Totally recommend doing the Master Screencaster Certification Course if you have an hour available.  Your teachers and students will have a blast with this.
