This document provides an overview of the evolution of rapid prototyping as an instructional design methodology from 1994 to 2015. It summarizes key papers that explored using rapid prototyping for instructional design and evaluated its effectiveness. The papers found that rapid prototyping could produce high-quality instructional materials in less time than traditional instructional design models by involving stakeholders throughout the iterative design process. However, rapid prototyping required attention to instructional design principles.
