• Design and validate a low-cost, reproducible photoelastic learning device capable of visualizing stress distributions while meeting constraints related to portability, manufacturability, ease of assembly, and classroom use. 

• Evaluate the effectiveness of hands-on photoelastic experimentation compared with traditional lecture-based instruction by measuring differences in student understanding of core conceptual mechanics of materials concepts. 

• Develop and execute a structured experimental study using pre- and post-assessments, student feedback, and statistical analysis to quantify learning outcomes and evaluate the educational impact of the device. 

• Document the design methodology, experimental results, and educational findings in a peer-reviewed conference paper to support replication of the device and contribute to engineering education research. 

Each iteration addressed limitations identified in the previous design, progressing from basic proof of concept to functional, reproducible learning device

Final Prototype Components:

• LED Board - Provides uniform light source.

• Adjustable Beam Supports - Allows the setup of multiple beam geometries and standard support configurations.

• Storage Drawer - Stores up to four different beam geometries.

• White-Light Diffuser - Distributes light evenly across the beam.

• Battery Bank - Supplies power to support portable operation.

• Acrylic/Polarizing Viewport - Integrates optical viewing window to observe stress-induced birefringence and fringe patterns.

• Attended technical and educational sessions focused on emerging topics in engineering education, including Geometric Dimensions & Tolerancing (GD&T), artificial intelligence, and the integration of Computer-Aided Design (CAD) tools into the classroom. 

• Presented my work-in-progress research on the Photoelastic Learning Device to engineering facultry, researchers, and professionals from institutions around the world. 

• Engaged with educators, researchers, and industry professionals to exchange ideas, discuss emerging technologies, and build connections with other like-minded individuals.
