In this session attendees will be introduced to Model-Evidence-Link (MEL) instructional materials designed to assist American learners as they construct arguments to evaluate the plausibility of evidence connected to models and the research base that supports using these scaffolds. These MEL diagrams allow students to think critically about socio-scientific issues by evaluating connections between lines of evidence and alternative explanatory claims.
Explorations that utilize the MEL scaffold promote changes in epistemic judgments, including claim plausibility, and help students move toward a more civically minded and scientific stance. Student discourse is a critical part of these activities and include negotiation toward scientific consensus.
MEL activities for available for teaching about socio-scientific issues include climate change, dead zones, energy, extreme weather, fracking, freshwater resources, fossils, moon formation, nuclear energy, origins of the universe, soil and food security and wetlands.
