Research suggests that it is challenging for elementary students to develop conceptual understanding of trait variation, inheritance of traits, and life cycles. In this study, we report on an effort to promote elementary students' learning of hereditary-related concepts through scientific modelling, which affords opportunities for elementary…

Learning about heredity is important across the K-12 continuum. However, these ideas may be challenging for students. We examined third-grade students' ideas about heredity in the context of a new, six-week, model-based science unit that uses corn as a model organism to support students' ideas about heredity. We analyzed data collected during…

Background/Context: Science is in the midst of reform, shifting away from teaching science and mathematics in isolation from one another, toward a model that prioritizes integration of science, technology, engineering, and mathematics (STEM) learning environments. Since teachers are the most important factor in determining the success and…

The American legislation of No Child Left Behind resulted in a boom in scripted, prepackaged curricula for improving student outcomes. At the same time, greater attention to the needs of diverse populations also took prominence, resulting in a new area of study, culturally relevant/responsive pedagogy. The current view is that scripted curriculum…

Place-based environmental education draws on childhood experiences in nature that foster place-conscious connections to the local bioregion, and intentionally cultivate children's relationships with nature on a trajectory toward increased environmental literacy. Even though opportunities for children to bond with the local natural environment are…
