I really like your example of multi-functional. It highlights the challenge for hyflex. In order to do it well you need to understand the components – that is in order to do hyflex well you need to understand the affordances and challenges associated with face-to-face and with online – but not only that – the students also need to appreciate the affordances of the different media. If you want to have any hope of learner-learner interaction, the learners need to know how to interact in a hybrid mode. It is a challenge to teach in that mode, but it is also a challenge for students really learn in that mode.
