While PowerPoint lectures are more colorful, they are generally no more interactive than chalkboard lectures. The physics community has, to its credit, worked to use technology in a variety of highly interactive and effective ways including wireless classroom response systems that allow for in-class quizzing of students and MBLs (microcomputer-based laboratories) that free students from the drudgery of data collection so that they can spend more time understanding the underlying physical...
