On 28th November, 2024, Intern Design Instructor (2024/25), Gala Cervera and other officers and executives of Chain For Change conducted a workshop at Namuna Machindra School, Lagankhel, featuring the 3D Geometrical Board, Parts of Brain, Map of Nepal and Modular Stylus. The session was designed to help students with visual disabilities grasp basic geometric concepts using a 3D geometric board. It also introduced them to the different parts of the brain and helped them explore the shape, size, and provinces of Nepal through a 3D map.

To assess the learning growth of the participants and effectiveness of the 3D models, we use different modality of administrating pre and post tests. We used clay to create two additional 3D models to see how they improve understanding of a subject. Participants with visual disabilities showed significant improvement in their understanding after interacting with the 3D models compared to their initial knowledge. The models included the shape of the brain and a map of Nepal.

For the 3D Geometrical Board, we used a shorter, four-question test to evaluate the model's impact. Pre-test scores averaged 1.5 out of 4, while post-test scores averaged 3 out of 4, reflecting an impressive 37.5% growth in learning. Students gave the geometrical board a perfect score of 5 out of 5, highlighting its tactile and interactive features as a valuable complement to traditional textbooks.

The participants were also given a 3D modular stylus to gather their experience and choice of selecting a fitting shape or style to write. The positive feedback affirmed the effectiveness of the 3D models in creating an inclusive and engaging learning environment, further supporting their potential to enhance accessible education.
