A Universally Designed for Learning (UDL) Infused Technological Pedagogical Content Knowledge (TPACK) Practitioners' Model Essential for Teacher Preparation in the 21st Century

This article challenges educational computing researchers and teacher educators to consider a merger between universal design for learning and technological pedagogical content knowledge to create a practitioners' model to prepare teachers to graduate with the knowledge, skills, and dispositions needed to teach the full spectrum of learners. Presently, these models are being developed on parallel tracks because of the existing bifurcated system of general (regular) and special education. The two models together would create a cohesive, comprehensive, theoretical model for the preparation of 21st century teachers.
