It (LEARNZ) is the best online learning community I know of for NZ students. Working with real scientists on real issues and practical matters such as preparing for a tramp really fired the imaginations of my students. It has been fantastic for my ESOL learners, particularly the videos and it is great to be able to listen to the text as well.
