Climate change, and the rise of the natural hazards that climate change brings, has been at the top of news feeds every week over the past year. Extreme events such as floods, droughts, and wildfires are expected to increase in the future. What does that mean for those of us living in the path of one of these hazards? Our GeoHazard project is exploring this question with middle and high school teachers and students across the country.

Understanding Earth’s tectonic plate system dynamics is complicated though it is the central paradigm to explain transformations of Earth’s surface. The landforms and geodynamic events resulting from plates interacting are too massive to observe at scales of human experience. It is difficult for students to connect plate movements to geologic features like the Andes Mountains and geodynamic events like earthquakes. As such, the conventional teaching of plate tectonics rarely involves student-led systematic explorations.

Our planet’s surface is in constant motion. Large pieces of Earth’s crust and upper mantle, known as tectonic plates, continually move toward and away from each other at a rate of millimeters to centimeters each year. Over geologic time, their relative motions determine everything from the types of boundaries they form to the distribution of rocks and landforms on Earth’s surface and the location and frequency of earthquake and volcanic eruptions.

The present study focuses on examining transitions in elementary pre-service teachers (PSTs)’ understanding of, and skills in, leading argumentation-focused discussions in mathematics during participation in a sequence of three different practice-based activities, collectively referred to as the Online Practice Suite (OPS). We will examine 14 PSTs’ responses to post-activity surveys targeting their understanding of argumentation-focused discussions and emotional experiences, over the course of a single semester.

In this study, our team developed and is studying the use of an Online Practice Suite (OPS) composed of a coordinated and scaffolded collection of three practice-based online simulations designed to support the development of preservice teachers' (PSTs’) abilities, skills, beliefs, and understanding around one ambitious teaching practice within mathematics and science: facilitating discussions that engage students in argumentation.

We describe an online citizen science platform for human brain and behavior research that uses a participatory science learning approach to engage learners in the full spectrum of scientific inquiry.

School-based science inquiry tends to focus on already answered questions. We describe how we used the COVID-19 pandemic in a high school citizen science unit for students to witness and engage in real-time science. High school students developed proposals to study questions about their experiences related to the pandemic. Teacher and student interviews and observations showed that this globally-relevant experience also offered a personally relevant context through which to understand the scientific process.

We explored the COVID-19 pandemic as a context for learning about the role of science in a global health crisis. In spring 2020, at the beginning of the first pandemic-related lockdown, we worked with a high school teacher to design and implement a unit on human brain and behavior science. The unit guided her 17 students in creating studies that explored personally relevant questions about the pandemic to contribute to a citizen science platform.
