Description / Abstract
In this study, a design-based research approach was used in the creation of data-rich problem (DRP) tasks intended to support students constructing knowledge about food webs and ecosystem dynamics, specifically the effects from a loss of species. This iterative process of DRP task creation included qualitative results from two rounds of interviews. The interview results informed the creation of a set of DRP tasks that were implemented in two 7th grade science classrooms. Qualitative results from the culminating assessment demonstrate that students reached proficiency in “dissipation vs. persistence” and “energy arrows concepts”, and are approaching proficiency in “linear vs. nonlinear” and “food chain concepts”. These findings provide evidence of the effectiveness of design-based research and data-rich tasks in promoting students’ understanding of ecosystem dynamics.
