Universal Design for Learning

Designing courses for all learners creates more opportunities for success by offering multiple ways for them to access content, participate in learning, and demonstrate knowledge. The Universal Design for Learning (UDL) framework, developed by CAST, helps instructors remove barriers to learning in their course(s). This helps to create a more equitable environment for everyone, including those with diverse learning needs, neurotypes, and disabilities.

The purpose of UDL is not to make a course easier or less rigorous, but to remove unnecessary obstacles so that all students can fully engage with challenging material and meet the same learning goals.  

Designing your course with UDL strategies can:

  • Save instructors time by reducing the need for individual accommodations – when accommodations are built-in for everyone, you don’t have to adjust for each student.
  • Cut down on student emails. Flexible deadlines mean fewer case-by-case extension requests.
  • Make materials more accessible across technologies like screen readers, increasing your course’s impact.

Examples of Barriers

Learning barriers in the classroom can include:

  • Lectures and materials only offered in one format, leaving some students struggling to follow.
  • Timed tests and exam distractions, adding stress and hindering performance.
  • Requiring only one way to show participation (e.g. awarding points for verbal participation only), putting at a disadvantage students who need more time to process or communicate.
  • Inflexible attendance and deadline policies, forcing students to choose between their education and well-being.

UDL Strategies to Address Barriers

Many instructors at Cornell might not be aware that they are actually already using a number of Universal Design for Learning strategies in their course design.

This includes providing multiple ways to:

  • Engage students (videos, discussion, examples).
  • Deliver content (text, audio, visuals, notes).
  • Demonstrate learning (papers, projects, presentations).

In doing so, students are provided with several choices and options for the formats, activities, and approaches that best support their needs.

A Three Step Approach for Instructors:

Step 1: Identify an area of need. Determine which part of your course might be a barrier for students. 

  • For example, you may have received many accommodation requests in a particular area, or students may have repeated questions about the same course requirement. An anonymous survey early on can help determine needs.

Step 2: Reflect on these barriers more deeply. Why and how is it affecting your students differently?

  • e.g., extra time: What part of the exam is a barrier for individual students? What are the different reasons for this? How is it different for various students?

Step 3: Adjust your course: How can you modify these parts of your course to address the specific barriers affecting students? If course adjustments feel overwhelming, remember it’s OK to start small, addressing one barrier per semester.

Goal for Instructors: Remove One Barrier Per Semester

“If you can do one thing per semester, by two years, you’ll have changed your class in four different ways.” – Dr. Flor Ardon, study skills lecturer and neurodivergent student support program manager

The strategies below provide common barriers and UDL strategies for the type of course you offer. Remember, you know what is best for your course, discipline, and field, and are the best judge for which ideas will be most appropriate for your course, and how to implement them.

UDL by Syllabus Policy

Participation

Common Barriers: 

  • Social anxiety, neurodivergence and others can be very affected by verbal-only participation or group work.
  • Cold-calling students (creates extreme anxiety for many).
  • Fast-paced discussions.
  • Cultural or academic norms for participation (more listening to show respect).

UDL Strategies:

  • Penalizing students for missing class due to work conflicts or transportation issues.
  • Assuming all learning happens in real time.

UDL Strategies:

  • Offer a set number of excused absences without requiring documentation.
  • Provide make-up opportunities that are accessible and manageable (e.g., short reflections on missed content) Here is an example of an extension policy (Sarvary, 2024).
  • Use an attendance flexibility policy (e.g., students can miss up to three classes without penalty. If more are needed, please reach out in advance.).
  • Avoid grade penalties based solely on attendance. Instead focus on engagement with course material.

Due Dates

Common Barriers: 

  • No flexibility in deadlines.
  • Strict late penalties.
  • One-size-fits-all extensions.
  • Too densely packed deadlines.
  • Deadlines are front loaded in first half of semester, meaning students are unable to improve grades in second half).
  • Everything due at the end. This unstructured approach does not work for many.

UDL Strategies:

  • Spread out deadlines with breathing room in between assignments.
  • Provide enough due dates in second half of semester to give opportunities to improve grades.
  • Implement a “grace period” for assignments with no penalty. Consider offering two separate due dates, with emergency token (Sarvary, Ruesch, 2024).
  • Allow students a limited number of self-managed extensions, no questions asked.
  • Offer alternative deadlines for students with accommodations or unforeseen circumstances.
  • Use scaffolding (e.g., smaller check-ins or drafts) to prevent last-minute deadline stress.

Grade Breakdown

Common Barriers: 

  • Few high-stakes, single mode assessments (e.g., one big test or final paper) are basis for grade..
  • Complicated grading system (hard for students to calculate and track).
  • Unknown grades: Not posting grades means students are unsure of progress.
  • Unbalanced weighted grades. Students may not do low-value assignments, or, alternatively, a too heavily valued assignment might tank a student's grade.

UDL Strategies:

  • Offer multiple assessment types (e.g., projects, presentations, reflections, discussions, active learning participation).
  • Provide several low-stakes opportunities, such as smaller deliverables or quizzes. A scaffolded approach could provide students with room to fail and develop.
  • Provide rubrics ahead of time to communicate how to be successful and how student scores are determined.
  • Consider a resubmission/revision for growth mindset, which values learning and improvement over performance.
  • Post grades on Canvas early and frequently if possible.
  • Provide a straightforward grading system, such as a weighted or point system that the student can calculate.

Technology Use

Common Barriers:

  • Use multiple modes of communication (e.g., email, discussion boards, office hours) and check in often via different formats (e.g., in person, anonymous survey, discussion board).
  • Develop a collaborative community agreement for interaction during class.
  • Clearly state expected responses times for emails and how you prefer they are written. See this list of email dos and don'ts for students (Sarvary, 2024).
  • For large classes, explain communication triage (e.g., talk to peer first, then discussion board, then TA, then instructor if absolutely needed).

Textbooks

Common Barriers: 

  • Requiring expensive or proprietary textbooks.
  • Assume equal access to course materials (delays in obtaining accessible versions).
  • Reading is too dense.
  • Unrealistic expectations: If too much reading is assigned, students may avoid the assignment.

UDL Strategies:

  • Choose open educational resources when possible.
  • Ensure materials are available in accessible formats, such as EPUB, screen-reader-friendly PDFs, audio version, or web based methods.
  • Allow students to use older or digital editions when possible.
  • Choose readings that are appropriate for their level.
  • Assign an amount of reading that matches the credit load, a full academic schedule, and outside life circumstances that may arise.
  • Collaborative reading tools, such as Perusall, can provide students with support and answers to questions.
  • Suggest students preview the reading to better plan their time commitment.

Office Hours

Common Barriers: 

  • Limited scheduling options.
  • Not understanding the purpose of office hours.
  • Only offering in-person office hours.
  • Intimidated by the professor or concerned about taking up their time.

  • Offer resources in multiple formats (e.g., audio, text, screen-reader compatible).
  • Provide summaries or guided reading questions.
  • Break up reading into smaller chunks with clear goals for each.
  • Prioritize essential readings and clearly mark optional content.
  • Offer Cornell CAMP, previous book editions, or library copies for students needing textbooks.
  • Use articles instead of a textbook.
  • Explain why the reading is important and meaningful (e.g., preview the content and provide context and information about the author(s).

Communication Expectations

Common Barriers: 

  • Difficulty keeping up with notetaking while processing.
  • Challenges organizing or understanding notes later.
  • Limited access to notes if class is missed.
  • How to take notes for a particular class.

UDL Strategies:

  • Share instructor or peer notes regularly. Promote collaborative note-taking tools (e.g., Google Docs, OneNote, Evernote).
  • Allow lecture recording or offer an outline to support in-class engagement.
  • Offer graphic organizers or alternative note formats.

Explore a Cornell-specific notetaking method.

Recordings

Note: Recordings support a wide range of diverse learners. If you’re concerned recordings may reduce attendance, it can be helpful to consider and communicate with your students what they gain by attending your class. For example, does class attendance offer active learning, skill-building, or critical thinking opportunities they can’t get from a recording?

Common Barriers: 

  • Inability to attend class due to health reasons or multiple challenges that may arise in life.
  • Difficulty concentrating during long lectures/recordings.
  • No captions or transcripts, limiting accessibility.

UDL Strategies:

  • Record all class sessions and post promptly.
  • Include transcripts and captions.
  • Highlight key sections.
  • Allow adjustable playback speed and easy navigation.

Canvas or LMS (Learning Management System)

Common Barriers: 

  • Inconsistent organization can cause confusion.
  • Important materials may be buried or labeled unclearly.
  • Difficulty tracking deadlines or finding updates.

UDL Strategies:

  • Use a predictable weekly structure and consistent layout.
  • Label folders and content clearly (e.g. “Week 2 Readings”).
  • Post weekly overviews and checklists.
  • Minimize clicks to reach key materials and keep all resources in one place.

UDL by Learning Activity

Individual Activities

Common Barriers: 

  • Not quiet enough.
  • Students may need more time or flexible timing.
  • Varying levels of background knowledge or readiness.
  • Writing or processing challenges.
  • Students may be easily distracted and learn better with others.

UDL Strategies:

  • Allow flexible timing or asynchronous options.
  • Break down tasks with clear instructions.
  • Offer multiple formats (e.g., video, visual, audio, text).
  • Offer an opportunity to work with partner if it works with the learning outcomes.

Partner/Group Work

Common Barriers: 

  • Group dynamics may disadvantage some students.
  • Not knowing the directions for an activity.
  • Peers choosing not to participate.
  • Some find socializing distracts from learning, making it hard to switch from lecture to interaction.
  • Language or cultural barriers.

UDL Strategies:

  • Provide choices and options for students to participate with group or on their own (unless the teamwork skill is part of learning outcomes).
  • Roles are assigned to practice a variety of skills.
  • Change up groups regularly, e.g., some days can involve pair-work, and some larger groups.
  • Use a structured group activity with clear roles so everyone contributes. Have members submit group names for attendance and participation.
  • Pair multilingual students strategically to not get isolated in a group.

Class/Discussion

Common Barriers: 

  • Intimidating to speak in class. Not everyone feels safe or included.
  • Some students may process ideas more slowly, making it hard to keep up with the flow of conversation.
  • Unable to prepare fully.

UDL Strategies:

  • Start with individual/small groups to warm up and gain confidence and write down ideas, then work up to a whole class discussion.
  • Provide instructions in more than one format (e.g., verbally and on a handout or a slide).
  • Structure the discussion to make it easy to jump in. Strategies to encourage broad participation.
  • Offer multiple ways to participate (e.g., verbal, chat, written reflections, or assign roles).
  • Provide a rubric so students know how to be successful.
  • Start with students providing a summary of the reading.

Polling

Common Barriers: 

  • Real time tools can move too fast.
  • Tech issues.
  • Pressure to answer publicly can cause anxiety.
  • Students can’t afford the clicker or app.

UDL Strategies:

  • Keep polls open after class if possible. Note that this is not appropriate if using polling for attendance.
  • Use anonymous formats to lower pressure.
  • Provide alternatives (e.g., written submission or asynchronous polls).
  • Summarize poll results to reinforce key takeaways. Discuss why answers are right and wrong.

Worksheet

Common Barriers: 

  • Different paces for completing tasks.
  • Difficulty with handwriting or organizing thoughts on paper.
  • Inflexibility with formats may exclude some students.

UDL Strategies:

  • Offer digital and editable versions.
  • Include directions with clear goals.
  • Use visual scaffolds (e.g., tables, diagrams, timelines).
  • Allow completion outside of class for flexibility.

Peer Review

Common Barriers: 

  • Unequal preparation or unclear expectations.
  • Social discomfort giving or receiving feedback.
  • Time constraints or inconsistent scheduling.

UDL Strategies:

  • Use structured peer review forms or rubrics.
  • Train students on the type of feedback you want them to give. Incentivize effective feedback and implementing others’ feedback. Normalize this process. Start with simple content.
  • Allow multiple formats for feedback.
  • Make deadlines flexible.

Communication is Vital

To identify learning needs early on, let students know in writing and in class that you’re committed to supporting them, and invite them to share any needs or barriers through a survey, office hours, or a quick check-in.

Some students may feel intimidated and reluctant to bring their concerns to light. We encourage you to set an approachable tone in the classroom by making it clear you welcome these conversations without judgment and do not expect students to disclose personal information. 

You might also share your own teaching needs, such as timing for questions, assignment formatting, or ways students can make themselves more visible and audible in class.

Key Takeaways

  • Many barriers in higher education are not physical but are built into course policies and design (Carillo-Sierra et al., 2025).
  • Rigid attendance, participation, and assessment policies disproportionately impact students with disabilities, health struggles, emergencies, or financial constraints (Edwards, Poed, Al-Nawab, & Penna, 2022).
  • Course materials and teaching strategies often assume one ideal learner, excluding those who learn differently (Reyes, Meneses, & Melian, 2022).
  • More flexible, inclusive approaches can significantly improve accessibility and student success (Reyes et al., 2022).
  • Preparing students for the real world means supporting them through challenges with appropriate accommodations, not simulating hardship. Resilience grows through supported rigor, not unnecessary barriers (Fullerton, Zhang, & Kleitman, 2021).
