The Case for Instruction Modeling
Relying on the examples and lessons of the preceding chapters, this chapter offers a case for the use of instruction modeling. The central value of instruction modeling is that it offers a consistent way to develop high-quality instructional content for blended learning programs. While this may appear insignificant, in reality it is of great importance. Good instructional traditions in mathematics are exceedingly rare, and have developed their content—including textbooks and the content of individual lessons—through decades of trial and error. Instruction modeling offers a way for designers to avoid the great risk of attempting to do the same from scratch. This is the theoretical case for instruction modeling; the practical case comes from the success of the specific blended learning programs developed through its use. We survey the research literature on the efficacy of these programs. The evidence suggests that instruction modeling is not merely a theoretically appealing approach but also one that can be used to develop programs that succeed in practical use.
