Evaluating a Craft-Based Platform for Teaching Linkages, Cams, and Structural Integrity Through Large-Scale Paper Models Abstract The growing emphasis on hands-on STEM/STEAM education has revived interest in low-cost, high-engagement construction kits. This paper analyzes Colossal Paper Machines—Make 10 Giant Models That Move (Storey Publishing, 2016) as a pedagogical and design artifact. Unlike traditional papercraft (origami, pop-ups) or static cardboard modeling, this book proposes fully functional, large-format (up to 24 inches tall) mechanical models driven by simple mechanisms. We examine the book’s underlying engineering curriculum: levers, cranks, gears, cams, and linkages, each embodied in a distinct project (e.g., a pirate ship with rocking motion, a moving dragon, a drawbridge). Through a critical review of the instructional design, material constraints (folded cardstock + fasteners), and scalability, we argue that the “colossal” scale serves a crucial cognitive function—making otherwise invisible force transmission visible and tangible. The paper concludes with recommendations for educators and designers wishing to extend this approach into classrooms or maker spaces. 1. Introduction Paper is traditionally associated with two-dimensional drawing or static three-dimensional folding. Colossal Paper Machines breaks this paradigm by offering templates and instructions for ten large, movable paper mechanisms. Each machine requires no electronics or glue—only cardstock, paper fasteners (brads), scissors, and a hole punch. The book’s explicit goal is to teach mechanical movement through crafting.
