She says "I think of the today's web 2.0 tools as a wardrobe for my class. A wardrobe is a collection of wearing apparel and accessories. My instructional wardrobe must consist only of those things that fit me and make me better as a teacher. I will share my wardrobe with you, but you must try on all sorts of outfits to see what fits you the best."
