This exploratory project develops and tests graphical scaffolds which facilitate high school students' coordination of connecting evidence with alternative explanations of particular phenomena, as well as their collaborative argumentation about these phenomena. At the same time, the project examines how high school students use these tools to construct scientifically accurate conceptions about major topics in Earth and space sciences and deepens their abilities to be critically evaluative in the process of scientific inquiry.

This project will develop, implement, test, and revise instructional approaches and materials for high school students that focus on the links between scientific evidence and alternative explanations of phenomena relating to Earth and space education. Students will learn to construct diagrams showing the links between explanatory models of natural phenomena and lines of evidence, and then evaluate the plausibility of various alternative explanations for events.

This project addresses tools to support students in reading and evaluating a variety of sources to compare various claims addressing socioscientific issues. It draws on literacy concepts from science education and social studies to develop and implement scaffolding tools that can support students' understanding of the links among data, evidence, and claims while considering the trustworthiness and plausibility of sources. The project will design and test such instructional scaffolds with the goal of helping middle and high school science and social studies students to deepen their evaluation skills as they make reasoned evaluations as expected of citizens in a functional democratic society.
