An interactive learning environment (ILE) appropriate for intermediate macroeconomics students has been simplified for students in introductory college and high school courses. Without changing the underlying model or the simulation options, the simplified instructional approach relies on feedback loop diagramming more than stock-and-flow diagramming. Interactive Vensim causal loop diagrams are embedded in a STELLA interface, using slide show and video software. In addition, students appear to learn more as model-users if they engage in preliminary model-building activities using simple word-and-arrow diagrams.
