This document summarizes two instructional design models: the Bates model and the Gentry IPDM model.
The Bates model, called ACTIONS, focuses on seven key factors to consider when selecting learning technologies: access, costs, teaching/learning implications, interaction, organizational issues, novelty, and speed. It also outlines four phases of instructional design.
The Gentry IPDM model emphasizes communication between the instructional development components and supporting components. It represents the necessary design components as 14 interconnected circles to complete an instructional unit using various techniques.
