In a British study, English, history, mathematics and science teachers used interactive whiteboards (IWB) and data projectors in various ways. A unique strength of IWB technology is that it allows teachers and students to revisit previous sessions of saved activity, which helps to reignite and build on earlier learning. The researchers also found that using IWBs can: provide new opportunities for learners to express themselves publicly, receive critical feedback and reformulate their thoughts, stimulate discussion, and allow teachers to adapt to individual learning needs.
