Hi Margie: There's so many really creative standard and variations of standard and alternative media out there; gosh, by standards of just a few year back, we have so much. That's why caution that just because something is "cool", doesn't make it necessarily right for for this class at this time. So, I look for variety, and mix it up. Change ups fairly often are appreciated by students, helping them stay focused, and keeping the instruction kind of fun, enjoyable, and interesting. Regards, Barry
