Kathy, The media we choose can make the difference between mediocre and outstanding, and when its a students education thats involved I don't think we should take the chance or settle for the lesser. These days there is so much media available, it's not just selecting media but choosing the best media, for these students, this time, in this class. It may vary the next go around. Variety is great. And we want to be sure what we choose results in giving the students the best material in order to learn. Barry Westling
