In this final chapter of our series, Rebecca Garelli presented strategies and examples for reshaping educational paradigms using UDL. The session was anchored around the driving question: How do we enact and modify curriculum to reduce barriers and leverage student resources? 

Rebecca began the session with a reflective activity, prompting participants to contemplate the diversity, strengths, and challenges in their classrooms, highlighting the urgent need for strategies like UDL. She then defined UDL as a proactive framework for optimizing teaching and learning, designed to accommodate learner variability rather than perceiving disabilities as deficits within students. 

She introduced the three main UDL principles, aligning them with the 'how,' 'what,' and 'why' of learning.

• Engagement: The Why of Learning. This principle revolves around stimulating students' interests and motivation to learn. It emphasizes creating challenges that are aptly suited to engage students, encouraging sustained effort and self-regulation.

• Representation: The What of Learning. UDL encourages presenting information in multiple formats to cater to different learning modalities. This approach allows students to grasp concepts in a way that resonates best with them.

• Action and Expression: The How of Learning. This principle focuses on providing students with different ways to express what they know. It promotes flexibility in assessments and encourages diverse means of demonstration, like models, drawings, or presentations.

Through a detailed walkthrough of OpenSciEd’s Mount Everest lesson, Rebecca demonstrated how each element of UDL was woven into the fabric of the lesson plan, creating a learning experience that was accessible, engaging, and effective for all students.

• Engagement Through Real-World Phenomena: The lesson began with an intriguing exploration of Mount Everest’s movement, particularly during an earthquake. This approach exemplified the first UDL principle, engaging students by connecting learning to real-world phenomena that evoke curiosity and interest.
• Diverse Representation for Comprehensive Understanding: By incorporating multiple media formats, including videos and text, the lesson showcased the UDL principle of Representation. This diversity in content presentation caters to various learning styles, ensuring that concepts are accessible to all students.
• Empowering Expression: In alignment with the UDL principle of Action and Expression, students are encouraged to represent their ideas through various means. Whether drawing models or discussing in groups, this approach validates diverse forms of expression, catering to individual strengths and preferences.

The webinar highlighted how UDL prioritizes the strengths and preferences of each learner, acknowledging that diversity in the classroom is not a challenge to overcome but a resource to embrace. Special attention was given to how UDL principles support learners with disabilities, emergent multilingual students, and students from culturally diverse backgrounds. Educators can ensure that all students are included by designing lessons with these considerations.

Rebecca highlighted the strategic nature of implementing UDL in science education. It’s about intentionally designing flexible and accommodating lessons from the outset. She also emphasized the educator’s role in delivering content and creating learning experiences that are adaptable, engaging, and respectful of each student’s learning journey.
