Fostering Model-Based Learning of Human Body Systems During Simulation-Based Investigations

• In Event: Assessing for Learning: Exploring Assessment Strategies for Supporting Conceptual Change

Abstract

The NSF-funded SimScientists Human Body Systems (HBS) project is testing simulation-based instructional modules with embedded formative assessments and a summative benchmark assessment for high school biology. Our theoretical framework integrates model-based learning (Author, 2000, 2012) with complex systems (Goldstone & Wilensky, 2008) in an evidence-centered design process (Behrens et al, 2004). After pilot-testing the modules in classrooms and making revisions, we conducted a randomized controlled trial in the classrooms of 40 teachers. From preliminary analyses we observed that despite a significantly lower mean pretest score than the control group, the treatment group posted significantly higher gains on the posttest. While the pretest score was the major predictor of gain on the benchmark test, there was also a significant dosage effect.
