Document Summary
Students can use models to test ideas, make hypotheses, revise their thinking, visualize their thinking, etc. Models make reasoning more public to class and teacher. Modeling is not a one-and-done event - it can constantly be revised. Students change their understanding of events or processes. A representation of a system or a phenomenon. Drawings, diagrams, charts, equations, graphs, simulations, replicas, etc. Some models describe, others explain (explanatory models) Must change in response to new forms of evidence about the world. To illustrate accepted science ideas (in the classroom) 6 strategies for meaningful modeling in the classroom: About an event that happens in a specific place and time, under specific conditions. Visual resemblance between the real conditions being modeled and what gets put on paper. Less functional forms for classroom modeling = computer simulations, graphs, equations, physical replicas. Cannot readily test, evaluate, or revise over time. Explanatory models use unobservable features/events/processes to explain what we can observe.
