Presentation varies according to the needs of the student, some need and prefer play based learning, others prefer a more didactic style. The structure is similar, some students prefer to have the sessions broken up, some want it to remain linear and continuous. I always try to include some passive learning in a lesson in order to allow students to have some degree of rest as a one to one lesson can be mentally tiring. Imagine gong for a long run and you tire in the middle, if you stop it is harder to start again, if you slow you can often catch your breath and start up again.
