The most important tools within a physical classroom are the people in it, the teachers and the students. Ultimately their attitudes, enthusiasm and desire are what will make something useful happen during a class.
It is fair to say that traditionally a teaching session would be led by a teacher and to some extent that should still be true today. However clearly there is a drive to engage students more, not just so that they are more attentive in class and respond when asked a question but so that they play a more co-creational role in learning.
One of the big changes that many teachers or lectures face is that shift from ‘sage on the stage’ to ‘guide on the side’.
