I found some detailed reflections on the last running of the course on a blog http://sylviamoessinger.wordpress.com/: the author is in Germany but writes in English, and she also has some interesting reflections on a MOOC about e-learning she took, and other aspects of teaching with technology. Her Google-course posts are here: http://sylviamoessinger.wordpress.com/category/google-powersearching/
I discovered the Google course because I was following links to information about Google's "course builder" online educational software https://code.google.com/p/course-builder/ You have to install it on your own server. There is some advice about designing online modules that I would describe as "cheap and cheerful" though it does recommend that you start by spending at least 30 minutes planning the teaching!
