In this three part series, four professors who teach graduate level courses on the design of instructional video games discuss their perspectives on preparing instructional designers to optimize game-based learning. Part I set the context for the series and one of four panelists discussed what he believes instructional designers should know about instructional game design. In Part II, two faculty members who teach courses on instructional game design presented their perspectives on preparing instructional designers for game-based learning. Part III presents a fourth perspective along with conclusion that contrasts the four views posited in Parts I-III. [For Part 1, see EJ881173; for Part II, see EJ891395.]
