I recently had this article brought to my attention by a colleague. It very practically discusses how to set up a computer, projector and iPad to function similarly to an interactive white board (IWB) using screen-mirroring software. The big benefit to this being firstly that it is cheaper than the costs of a full IWB, and secondly, that it can be more versatile than other portable IWB alternatives.
On the surface this sounds like a fantastic idea, and worth some consideration. The portability of the iPad, and the relatively high access to computers and projectors in my school makes this an appealing alternative to outfitting every room with expensive IWBs.
Of course, IWBs have their place in a school as well, and if placed in the proper classes, with teachers who have the passion and training to use them, they will and do pay enormous dividends for students. If you doubt the efficacy of these devices, see Marzano’s 2009 study published in Educational Leadership.
