I prefer face-to-face instruction because body language helps the tutor know if the information is being provided and understood. For example, in order to teach a language you need, you need a variety of teaching materials, so the way you teach depends on the subject you are teaching. Photography and computers, but math and physics classes only require pen and paper. Also, I am very patient, especially with children, and can repeat information over and over in different ways until it is fully understood.
