This post concludes a series of posts that looked at groupwork, asynchronous delivery, learning design, assessment, resources, and now affordances and ther online shift. Martin Weller offers here what I think is a good take: "consider what you can do differently online rather than just replicating f2f". I think this is important. People often talk about designing ed tech based on use cases or problems to be solved, but I find that these are often rooted in existing practice. What new technology affords us is the opportunity to go beyond existing practice and do things we haven't been able to do before.
