This document discusses effective uses of technology in the classroom to engage students. It begins by posing questions about whether technology fundamentally changes instruction and if it is an add-on or integral to good teaching. Several quotes emphasize using technology to expand student interactions. A framework is presented for evaluating technology use based on whether it enhances physical, social, and cognitive interactions. Research on effective instructional strategies is shown along with examples of how technology can support each strategy. Guidelines are given for selecting software based on the interactions it provides and designing lessons around tasks rather than just incorporating technology. The presenter's contact information is provided at the end.
