The use of technology in the classroom can enhance student learning by increasing the exposure that students get to material, as well as diversifying the formats of this exposure. Technology provides the teacher with more ways in which to present material and aid student learning (e.g. aural, visual, demonstrations, applications). David Brown states, “The computer assists professors in their delivery of the picture that is worth a thousand words, of sound accompanying text, of attention-grabbing animation.” A PowerPoint presentation of a lecture’s outline can help students see where the class is going and how to organize their notes. Videotaped demonstrations can be used when in-class demonstrations are not feasible, or when presenting the information to a large class that would have difficulty seeing an in-person presentation. Images or videos can be presented to reinforce lecture material.
