This document discusses assistive technology for English as a second language (ESL) classrooms. It outlines principles of universal design for learning that ensure equal access through barrier removal and allowing students to choose how they represent, engage with, and express their learning. Assistive technologies on a continuum from low to high tech are described, including examples like word processors, screen readers, and text-to-speech software. The implications for ESL instruction include using multimedia, translation tools, and computer-assisted language learning software to modify and differentiate instruction for students.
