Theory & Principles
This section provides an in-depth look at the Universal Design for Learning (UDL) framework, developed by CAST. The three principles of UDL, along with their guidelines and checkpoints, are explored providing a comprehensive understanding of the theory and principles behind the framework – and as aligned with the concept of fostering the development of expert learners.

Principles of the UDL Framework
The Universal Design for Learning (UDL) framework was formally developed by CAST (Center for Applied Special Technology) in 1984 as a way to translate insights from neuroscience and the wider learning sciences to extending the goals of universal design to the learning environment. Over the years, while the framework has been periodically updated to incorporate emerging findings and insights from the broader learning sciences, the three (3) guiding principles when designing or developing learning experiences have remained consistent. They are:
Principle 1: Provide Multiple Means of Engagement
In the previous section, we discussed how functional limitations not only operate invisibly but also overlap and intersect to present more complex barriers to learning. This principle seeks to recognize the complexities that can exist in the learning process and encourages us to seek ways to motivate and engage students better. CAST (2024) identifies the “affective networks” of the brain (including the corpus callosum and hippocampus) as being related to the “WHY” of learning.

In providing multiple means of engagement, CAST (2024) has further broken down this principle into providing options for:
Recruiting Interest
“Information that is not attended to, that does not engage learners’ cognition, is in fact inaccessible.”
Sustaining Effort & Persistence
“When motivated to do so, many learners can regulate their attention and affect in order to sustain the effort and concentration that such learning will require.”
Self-Regulation
“The ability to self-regulate – to strategically modulate one’s emotional reactions or states in order to be more effective at coping and engaging with the environment – is a critical aspect of human development.”
Providing a variety of options focuses on ways to improve learners’ engagement throughout a learning experience by better tapping into their interests and motivations. For example, courses that include explicit learning outcomes and connect the learning outcomes to broader elements of learners’ university experience and/or their professional journeys make these goals salient and easy to remember, which helps students stay engaged throughout the course.

Principle 2: Provide Multiple Means of Representation
In keeping with the values of Accessibility and acknowledging Jaggedness in learner needs, this principle acknowledges that learners process information differently depending on the format, style, and medium used, and that information is not truly accessible to learners unless they are able to effectively access and process it. CAST (2024) identifies the “recognition networks” of the brain (including the parietal, occipital, and temporal lobes) as being related to the “WHAT” of learning.

In providing multiple means of representation, CAST (2024) has further broken down this principle into providing options for:
Perception
“It is important to ensure that key information is equally perceptible to all learners.”
Language & Symbols
“inequalities arise when information is presented to all learners through a single form of representation…ensure that alternative representations are provided not only for accessibility, but for clarity and comprehensibility across all learners.”
Comprehension
“constructing useable knowledge, knowledge that is accessible for future decision-making, depends not upon merely perceiving information, but upon active ‘information processing skills.”
Providing a variety of options focuses on presenting information in flexible and varied ways so as to limit the dependence on any single medium. For example, course materials written in advanced, academic English and available only as text can present challenges for students with limitations in linguistic, information processing, or the post-secondary readiness domains. But if the same materials are accompanied by audio/video versions of the same information and with definitions and explanations of important terms, that vastly improves students’ ability to access and engage with the material.

Principle 3: Provide Multiple Means of Action and Expression
In keeping with the values of Jaggedness and Teaching to the Margins, this principle recognizes that learners vary in the ways they communicate information and demonstrate achievement of learning outcomes, and that these variations often exist due to existing limitations and not just preferences. CAST (2024) identifies the “recognition networks” of the brain (including the frontal lobe) as being related to the “HOW” of learning.

In providing multiple means of Action & Expression, CAST (2024) has further broken down this principle into providing options for:
Physical Action
“it is important to provide materials with which all learners can interact. Properly designed curricular materials provide a seamless interface with common assistive technologies.”
Expression & Communication
“it is important to provide alternative modalities for expression, both to level the playing field among learners and to allow the learner to appropriately (or easily) express knowledge, ideas and concepts in the learning environment.”
Executive Functions
“Associated with networks that include the prefrontal cortex, these capabilities allow humans to overcome impulsive, short-term reactions to their environment and instead to set long-term goals, plan effective strategies for reaching those goals, monitor their progress, and modify strategies as needed.”
Providing a variety of options focuses on expanding the ways students can demonstrate their learning and their achievement of course outcomes. For example, weak writers are not necessarily weak communicators, and assessments that offer options to submit deliverables in alternative formats such as audio, video, or visual means (e.g. infographics) can provide students the opportunity to demonstrate their communication skills in authentic, creative ways.

Reflection Point
Which of the three principles of UDL (engagement, representation, and action & expression) most resonates with you? What are some considerations within your context for striking a balance between the three in designing and developing your course and instructional materials?
Guidelines and Checkpoints
The principles of Universal Design for Learning (UDL) serve as broad guidance for how to think about incorporating flexibility, scaffolds, and supports into the learning environment. As previously state, the UDL framework further breaks down each principle into three (3) additional guidelines, each with their own checkpoints. In total, there are nine (9) guidelines and thirty-one (31) checkpoints within the UDL framework.
Struggling students are less likely to self-regulate and “monitor their own learning and…often do not have a very good idea about whether they have comprehended and mastered the information presented” (Ertmer & Newby, 1996, p. 5). Though a core tenet of education, students often need to be explicitly taught that learning is an ongoing process and that challenges and failures are some of the best opportunities to learn and grow; to learn how to motivate themselves and push through adversity.

As UDL is intended to be an instructional design framework, the objective of developing expert learners is intended to be discipline-agnostic and applicable across all contexts. The core qualities, per the UDL framework’s definitions, is that Expert Learners are “Purposeful and Motivated,” Resourceful and Knowledgeable,” and “Strategic and Goal-Directed.” Moreover, Ertmer & Newby (1996) argue that “a major function of all schooling must be to help create learners who know how to learn. By fostering the development of strategic, self-regulated, and reflective learners, it is hypothesized that this goal can be achieved” (p. 22). The development of these three areas is highly aligned with UDL’s providing for multiple means of engagement, representation, and action & expression.
Here is a video by Dr. Seanna Takacs entitled “UDL Basics for Course Design” which will further explore Expert Learners:

Each of these qualities is tied to one of the UDL principles, and the principles can be framed as mechanisms that aid in the development of these qualities in learners. For instance, the goal of providing Multiple Means of Representation can be interpreted as the development of learners who demonstrate motivation, engage purposefully with learning experiences, and possess the awareness and goal-setting skills needed to do so.
Another way to frame and approach the objective of developing expert learners is to dissect the 6 qualities into a broad inventory of knowledge, skills, and abilities that someone possessing that quality would be able to demonstrate (see table below). For educators, this can potentially be useful as a tool for thinking about how a UDL-aligned solution being considered might impact or interplay with existing learning outcomes.

Additional Ways of Learning about UDL
At various points in this resource guide, we’ve touched on the importance of considering how the accessibility of information is inter-connected with whether that information can be understood and comprehended by its recipient. As Universal Design for Learning (UDL) is a broad, comprehensive framework, it can present challenges for practitioners seeking to develop UDL-aligned options and solutions for their contexts. While the next section of the resource guide provides more detailed and specific guidance for faculty, here we outline some additional ways of developing an understanding and comprehension of UDL. Specifically, through its connections to other disciplines, through the lens of Universal Design, and through social-contextual means.
