Graphical Tools for Conceptualizing Systems Thinking in Chemistry Education

One challenge associated with introducing systems thinking in chemistry classrooms is the increase in content complexity that students face when they engage in this type of approach. Placing core chemical ideas within larger systems has promise, as long as students are not overwhelmed by the added complexity. Although there are many potential strategies for dealing with complexity, one common tool is to employ visual or graphical tools to help conceptualize the problem or system at hand. In part because systems thinking touches on many potential levels of implementation, there are different visual tools that are helpful in conceptualizing different aspects. Some tools, such as systems-oriented concept map extension (SOCME) diagrams and systemigrams, use methodologies often associated with concept mapping but add features that enhance their applicability in systems thinking. Object–Process Methodology (OPM), which has seen fairly wide use in systems engineering contexts, uses formally defined components an...
