Big Wall Chart Versus Classroom Needs:-tested STEM Insight..._matched Size! We recently installed the What is Computer Science? classroom poster by Daydream Education in our middle and high school STEM classroom. Measuring an impressive 33” x 23.5”, the laminated chart stands out as a vibrant and informative resource. Its size ensures key concepts like algorithms, binary code, and debugging are clearly visible from a distance, making it ideal for group learning. The design is both engaging and educational, featuring bright visuals that appeal to diverse learners. What we appreciate most is its durability—the lamination protects it from daily wear and tear. Though it’s large, it fits perfectly on our classroom wall without crowding other displays. Students often refer to it during lessons, and teachers find it complements our curriculum well. It’s a standout piece that balances aesthetics and functionality, making complex ideas accessible and exciting.
