Using a Data-Rich Problem (DRP) Task to Promote Student Understanding of Cellular Respiration within an Ecosystem
Thesis
Description: 

In this study a design-based research approach was applied in the creation of a data-rich problem (DRP) task intended to improve student achievement in cellular respiration at the ecosystem level; an identified area of difficulty and an area of focus in the Next Generation Science Standards covering Matter and Energy in Organisms and Ecosystems in High School Life Science. The respiration DRP task was embedded in an existing learning module developed by Maskiewicz (2006) using Ecospheres®. Qualitative and quantitative assessment data were collected from 100 high school biology students who participated in the weeklong Ecosphere® module. Results suggest that students from the experimental class, which participated in the Ecosphere® module with the DRP task, showed significant quantitative gains on posttest items focused on cellular respiration; whereas students from the control class, which participated in the Ecosphere® module without the DRP task, showed no significant quantitative gains in performance on cellular respiration items. Quantitative results also showed that students in the experimental class had greater posttest gains, as measured by g-values, than the control class in items that focused on matter transformation, decomposition, and energy transformation. Qualitative results from interviews and written responses showed that students from the experimental class progressed to deeper Levels of Achievement in cellular respiration than students in the control class. In conclusion, these findings provide evidence of the effectiveness of the design-based research approach in general and, in specific, the modified Ecosphere® module in promoting student understanding in cellular respiration, matter transformation, decomposition, and energy transformation.
