Abstract: Studying complex systems is increasingly important in many domains. Several features shared by complex systems hinder deep understanding. For example, understanding complex systems involves thinking about multiple interdependent levels, non-linear causality and/or emergence. Conceptual representations offer opportunities to become integrating frameworks across different domains. This study investigates how alternative conceptual representations embodied in hypermedia can help middle school students better understand a complex system, the human respiratory system. We designed two versions of instructional hypermedia based on structure-behavior-function theory. SBF is a conceptual representation that is part of the disciplinary toolbox of biologists and thus is an appropriate representation for learning in this domain. One hypermedia was function-centered while the other was structure-centered. We contrasted the instructional effects of these two alternative conceptual representations. Students using the function-centered hypermedia developed deeper understanding than those using the structure-centered version on one of the two measures. Implications and limitations are discussed.
