When teaching adults what kind of visual media and material is available? Teaching hours and how many students in the adult class training?

I prefer to have10 to14 students in adults classes.You have to be aware of the stage and its characteristics.They prefer to have active and dynamic classes.There are seven kinds of intelligence and you have to address one in each class after you set an intelligence test and write down the kind that is plentiful in each person.They like to have a model to talk about and they are very curious about their future.theree to4 hours weekly are fine.
