This project will provide an empirically-supported learning progression for a key scientific practice, scientific modeling. The specific instructional materials created as part of the project can serve as a model other developers can use to design materials supporting scientific modeling and other practices. The model for educative curriculum materials as a form of teacher support can be adapted to support teacher learning about modeling or other scientific practices in other curriculum materials.
Cluster Randomized Trial of the Efficacy of Early Childhood Science Education for Low-Income Children
The research goal of this project is to evaluate whether an early childhood science education program, implemented in low-income preschool settings produces measurable impacts for children, teachers, and parents. The study is determining the efficacy of the program on Science curriculum in two models, one in which teachers participate in professional development activities (the intervention), and another in which teachers receive the curriculum and teachers' guide but no professional development (the control).
This project investigates 3rd-grade students' model-based reasoning about hydrologic systems and how teachers scaffold students' engagement in modeling practices. The research builds upon existing modeling frameworks to guide the development and integration of a long-term conceptual modeling task into the Full Option Science System (FOSS) Water module. The data collected from this project can help inform science curriculum materials development and elementary teacher preparation efforts designed to foster reform-oriented, model-centered elementary science learning environments.
This project will develop a learning progression that characterizes how learners integrate and interrelate scientific argumentation, explanation and scientific modeling, building ever more sophisticated versions of practice over time using the three common elements of sense-making, persuading peers and developing consensus. The learning progression is constructed through students’ understanding of scientific practice as measured by their attention to generality of explanation, clarity of communication, audience understanding, evidentiary support, and mechanistic versus descriptive accounts.
