Has anyone had experience with Google's CS First at http://www.cs-first.com? I ask because while I've skimmed the videos and resources, I haven't really had the chance to use it with my kids. We're exclusively using the ScratchED curriculum guide + workbook. My point of view is that CS First seems like a great idea if you want to get non-technical parents to help mentor in the club but may be too restrictive/scripted for very small groups that only need one mentor and that mentor is technical enough. What do others think?
