Kurzinfo:
The use of a conceptual representation has been shown to help students orient their thinking about complex systems. We sought to refine and test this idea with ecosystems using the PMC (phenomena-mechanisms-components) conceptual representation. Using pre-post drawing task assessments, we test the hypothesis that after completing a PMC-evidence and explanation-rich ecology curriculum, students would create more mechanistic explanatory models. We found that post-intervention students created more mechanistically oriented models and in our post-hoc analysis found that model sophistication correlated with course achievement, even though models and modeling were not a significant part of the course grade.

Impact Statement This article highlights the use of a conceptual tool (as opposed to physical material) given to students as a resource for systems thinking. As we learn more about how people learn, conceptual tools appear to have the greatest effect in classroom practice. Given the low cost of using such tools, we suggest greater practice and research investment into conceptual/cognitive tools is warranted.
