Have you ever come across a child who is too shy to speak up in class but then produces the most thoughtful written work? Moodle is perfectly suited to these students, because it has a Forum and a Chat facility, both of which enable classes and their teachers to have a discussion without actually being together, in the same room. And often, the shy child will happily have their say online, where they can plan it out first and feel comfortable without the interference of their peers.
We're going to set some homework where the students will discuss, in general, the kinds of things to keep in mind when planning a riverside campsite. Hopefully, someone will realize it's not a good idea to have it too close to the water.
