Supporting Secondary Students in Building External Models is a collaborative project with Michigan State University and the Concord Consortium, funded by the National Science Foundation (NSF) to examine how to support secondary school students in constructing and revising models to explain scientific phenomena and design solutions to problems. This article describes the project and research plans.

This study sought to identify specific types of discussion-based strategies that two successful high school physics teachers using a model-based approach utilized in attempting to foster students’ construction of explanatory models for scientific concepts.

This study investigates student interactions with simulations, and teacher support of those interactions, within naturalistic high school classroom settings. Two lesson sequences were conducted, one in 11 and one in 8 physics class sections, where roughly half the sections used the simulations in a small group format and matched sections used them in a whole class format.

Background Inclusive STEM (traditionally known to stand for “Science, Technology, Engineering, and Math”) high schools are emerging across the country as a mechanism for improving STEM education and getting more and diverse students into STEM majors and careers. However, there is no consensus on what these schools are or should be, making it difficult to both evaluate their effectiveness and scale successful models. We addressed this problem by working with inclusive STEM high school leaders and stakeholders to articulate and understand their intended school models.

Assessing both knowledge of Earth science concepts and students’ scientific evaluations in making sense of these concepts is important to gauge understanding. In the Model- Evidence Link (MEL) diagram activities, students engage with Earth science content knowledge and evaluate the connections between evidence and alternative explanations. We have developed a rubric for assessing the quality of student evaluations when engaging in the MEL activity, specifically in the written explanations about the connections between evidence and explanations.

The Fracking Model-Evidence Link (MEL) activity engages students in a scientific discussion around the topic of whether or not there is a relation between hydraulic fracturing (fracking) operations and increases in moderate magnitude earthquakes in Midwestern US. With increases in fracking operations, it is important for students to understand how to weigh the connection between evidence and alternative explanations about associated phenomena.

Teaching with socio-scientific issues can be a challenge given the tug-of-war between the scientific, social, economic, and political perspectives upon which many topics can be viewed. However, in an Earth science classroom, socio-scientific issues provide a rich stage upon which various lines of scientific evidence can be weighed against alternative viewpoints. This article describes how a Model-Evidence Link (MEL) lesson can effectively be used to assist learners in weighing the plausibility of different viewpoints of the uses of wetlands, a socio-scientific issue.

Understanding how the Moon formed supports understanding of Earth’s formation and early history. The Moon Model-Evidence Link (MEL) diagram is an activity that has students weighing the connections between four lines of evidence and two different models explaining the Moon’s formation—capture theory and giant impact theory. By evaluating alternative models, students can improve upon their scientific literacy and understanding of scientific practices. Suggestions from classroom use of the Moon MEL will help teachers use this activity in a productive manner.
