Your own preferences
This is probably a good time to think about your own learning preferences. Think about the times when you had good and bad learning experiences and consider whether there were any common factors in terms of the methods and media.
If you are considering your own learning preferences, or if you are supporting a homogeneous group of learners, you will have a good idea of which types of methods and media you should be used. If you have a varied group of people, the chances are that there will be a fairly even spread of the four different types. In this case it would probably be advisable to have a wide range of differing methods and media so that you can reach as many different types of people as possible. (Have you ever wondered why the Bible has four gospels telling essentially the same story?)
