Universal Design for Learning (UDL)
Through the implementation of UDL principles and practices during the design stage of products and services (instruction), these products and services can be made accessible, understood, and usable by all people, without the need for intervention, accommodations, supplementary services/tools.

Accessible refers to the ability to obtain, use, and benefit from products (course content) and services (instruction), of both individuals with and individuals without disabilities. For example, an online document or tool can be accessed and understood by everyone regardless of the equipment used. Accessible content is created by following best practices in universal design for learning and accessibility.
An accommodation is an academic adaptation. If a student's documented disability can inhibit their academic success, they may receive a Letter of Accommodations from the Disability Resource Center listing the academic modifications necessary. These modifications are determined on an individual case-by-case basis.
Usability refers to the extent a product, device, service, and/or environment can be used by users to achieve specified goals, effectively, efficiently, and satisfactorily, in a specified context; it addresses average users, using standard equipment, with standard abilities, navigating and using a Web site.
Differential instruction is a process of teaching and learning in which an educator alters or modifies the current curriculum to address students' varying background knowledge, readiness, language, preferences in learning and interests so that each learner obtains the knowledge, understanding, and skills need to move to the next phase of learning (Hall et al., 2004).
