Background Essay: Visualizing Concepts Through Technology

Models can be useful classroom tools when you want to help students gain experience with equipment or procedures that are not normally available. Models can be physical constructions, or they can be computer simulations. Both might require students to manipulate data or objects.

Scientific models can clarify difficult concepts or simplify large-scale operations. The model in this video—a scaled-down refinery operating system—is an effective example because its design gives students an overview of the system, via its reduced size, and its use of glass to show key functions that would not be visible on-site. Models are a meaningful way to reach all learners and help them focus on the practical application of ideas.
