 My challenge of blended learning is not every students like that form of delivery. Some students still want to come in, sit down and just listen. They like to hear my experience. They like to hear my interpretation of some other. They do not see their colleagues, their peers as a good and reliable source of information. I recognise that because sometimes after a discussion when I ask them to reflect their learning on using one minute paper, they mix up all the information. They feel that they sometimes see what shared by their classmates is a fact when there's not true or they don't really listen to their classmates. So students still need to learn from their classmates, I think that's very important. But they also need to learn from their classmates with a critical mindset.
