Explaining phenomena associated with a system involves describing a system’s structure and articulating the process through which the system’s structure changes over time. This paper defines geo-sequential reasoning in the context of plate tectonics and uses it to analyse how students explain the geological processes that occur along convergent boundaries as part of the plate tectonics system. This study was part of design-based research on an online Plate tectonics module that included simulation-based modelling developed for secondary school students.

When integrated into online curriculum modules for students, educative curriculum materials (ECMs) can enhance teachers’ enactment of these modules. This study investigated (1) the use of digitally enhanced ECMs built into an online plate tectonics curriculum module by teachers with different backgrounds and teaching experience, (2) the relationship between teachers’ use of ECMs and student learning gains, and (3) teacher reflections on the value of the ECMs they used.

Science learning is an important part of the K-12 educational experience, as well as in the lives of students. This study considered students’ science learning as they engaged in the instruction of scientific issues with social relevance. With classroom environments radically changing during the COVID-19 pandemic, our study adapted to teachers and students as they were forced to change from more traditional, in-person instructional settings to virtual, online instruction settings.

While tragedy has struck an inordinate number of students in the past several years, not all areas of the country are at risk for every natural hazard all the time. To avoid having students feel like Chicken Little under a falling sky, the GeoHazard project uses simulations, data, experimentation, and scientific argumentation to teach about risk and uncertainty. We have created three scaffolded online modules focused on hurricanes, wildfires, and inland flooding to help teach these concepts.

Concord Consortium’s new Earth Rocks Map displays a generalized representation of Earth’s geology, focused primarily on the distribution of the three major rock types (igneous, metamorphic, and sedimentary). What makes this map different is that it strips out information about geologic eras, highlighting the distribution of rocks found on Earth’s surface.

The Innovate to Mitigate project adapts crowdsourcing to support project-based STEM education, posing design challenges for secondary-school students. Students are charged with designing feasible innovative strategies to mitigate CO2 emissions and thus global warming. The paper draws on data from 3 project teams. The paper presents evidence that a web-mediated community of practice supports STEM learning of concepts and STEM practices and examines conditions under which the environment can enable an account of microgenesis of that learning.

Today’s students are exposed to news about wildfires on an all-too-regular basis. An increasingly larger portion of those students live in areas where wildfire risks are high or where smoke has reduced the air quality. The GeoHazard project has designed, developed, and tested an online wildfire curriculum module for middle and high school students that addresses the factors that influence wildfires, as well as the risks and impacts that wildfires bring to people and their communities.

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.
