Learning Progressions for Environmental Literacy Why do we need biodiversity literacy? • Biodiversity is rapidly declining
Learning Progressions for Environmental Literacy Why do we need biodiversity literacy? • Species perform vital ecosystem functions/services.
Learning Progressions for Environmental Literacy Why do we need biodiversity literacy? • The more diverse a population or community is, the more resistant it might be to perturbations like disease
Why do we need biodiversity literacy? How much do citizens need to know to make sense of the information in popular media and policy? How can a reader decide whether to trust claims, especially when reports are contested in popular press? Should we expect citizens to make or accept changes in policies that affect them on the basis of simplified popular media, leaving “technical details” to the experts?
Learning Progressions for Environmental Literacy Goal of our Work • Develop a grades 6-12 learning progression for biodiversity
Learning Progressions for Environmental Literacy Our working definition of a learning progression • Learning progressions are descriptions of increasingly sophisticated ways of thinking about a subject. • Conceptual coherence: “make sense”/ tell a reasonable story • Empirical validation: grounded in empirical data about real students • Compatibility with current research: built on findings of the best research about both student learning and scientific thought
Learning Progressions for Environmental Literacy Informed by, builds upon, corroborates • Anderson • Catley, Lehrer, and Resler • Duncan • Furtak • Metz • Nehm • Schauble and Lehrer • Songer and Gotwals • and others

Methods Learning Progressions for Environmental Literacy Observe patterns in student thinking (literature search and pilot studies) Define ContentArea Construct a model about we how think students progress Revise the model teaching experiments assessments Test the model
Learning Progressions for Environmental Literacy Methods Written Assessments (MD, NY, CO, MI, CA)
Learning Progressions for Environmental Literacy Methods Clinical Interviews (MD, NY, CO, MI, CA) Written Assessments (MD, NY, CO, MI, CA)
Learning Progressions for Environmental Literacy Methods • Created rubrics for each item with 10 student answers • Attempted rubrics with 30 student answers, refined rubrics • Used rubrics to code interview data • Refined rubrics • Eliminated unreliable questions • Coded all student answers with refined rubrics • 10% of answers were coded by multiple coders • Less than 80% reliability led to another round of developmental coding • IRT analysis is on-going

Learning Progressions for Environmental Literacy Characteristics of Levels: Individual Scale • See individuals as static life forms recognize change in individuals over life cycles and seasons • Type I survivorship curves Type II and III survivorship curves • Recognize traits of individuals connect trait with function and environment
Learning Progressions for Environmental Literacy Characteristics of Levels: Population Scale • Recognize Individuals/families recognize populations within communities • Traits of individuals shaped by free will traits shaped by genetics moderated by environment • All survive survival in face of strong selection pressures recognize reproduction as important, recognize weak as well as strong selection • Phenotypic plasticity as rationale for “free will” explanation as rationale for genetic explanation • Change within generation long-time generational time
Learning Progressions for Environmental Literacy Characteristics of Levels: Community Scale • See direct biotic interactions also see indirect, resource-mediated interactions, see time lags from action to response • Simplistic view of connections recognition of variable strengths of connections, recognition of functional redundancy • Change only from catastrophic events or human intervention change as constant and mediated by interplay among biota and abiotic environment • Isolated landscapeslandscape mosaics • don’t invoke dispersal see dispersal as important and moderated by traits
Future Directions • Teaching Experiment (N=1200) • Revisions of 2010 Assessments and Framework • Plasticity • Importance of weaker selection pressures • Socio-ecological contexts • Differences among students • Demographics • Schools and teaching practices • Incorporating learning progression teaching strategies into our teacher professional development
