Thanks for the response. It pushed me to think a bit further about the purpose and whys of using a whiteboard. Really for me it is student ownership of content, not so much learning vocabulary, we have enough tools such as Peek for that as you mentioned. From what I've seen in terms of using various media, the students love using whiteboard pens and the write/erase/re-write immediacy of their usage over something involving pens, pencils, which is one reason I was thinking it would be appealing. Also something I left out is that I will ask them to illustrate the concept or word as well, doing this with larger canvasses for a group project is easier, and I think students take less offense at content getting deleted whether accidentally or purposefully by group partners on a white board then a large sheet of paper.
