Hi Margie: You've identified some good points. It is key to degine what it is that needs to be taught, then deciding on how best to deliver that material. Variety in media selection definitely makes a difference. But also, choosing the correct media for the lesson is also inportant. Keeping the students in mind helps focus what resouces will attain both effective learning and interest by the students. This activity takes time, thought, effort, planning, and communication. And it should be reviewed by peers or supervisiors who are willing to make constructive comments. Regards, Barry
