Kind of a neat analogy: "Terraforming the environment for sustainable e-learning life." We can talk about what counts as good e-learning by talking about what counts as good terraforming. If your newly terraformed planet requires that its new colonists grow gills, it will not count as successfully terraformed. The planet must correspond to the actual living and breathing needs of the colonists. Now the online world, of course, is always terraformed. Yet given this, it's suirprising how many sites expect that students can breather underwater - or at the very least, ought to learn. View the link to the slides at the bottom of the article.
