The document discusses different types of instructional materials used as substitutes for real things in the classroom, including models, mock ups, specimens, objects, simulations, and games. Models are reproductions of real things in a small or large scale made of synthetic materials. Mock ups arrange real or associated devices to present reality. Simulations represent manageable real events where learners actively participate, and games are plays with rules where someone wins or loses.
