As part of my recent Google Education Trainer application, I created this 2 minute video which highlights tips and best practices when it comes to creating Google Sites in Google Apps for Education domains.
I used Camtasia to record the on-screen demonstrations, and Sony Vegas to produce everything else.
Another pre-requisite for the Google Education Trainer program is to have achieved the Google Educator certification, to which, I have attained. I found this process extremely valuable and useful for my own practice back at school. I would recommend anyone who is wanting to further their development and understanding of the mechanics of the various Google Apps on offer should study the comprehensive coursework and even take the exams.
