New Directions at the Intersection of Research about Earth and Research on Learning

New advances in cognitive psychology and learning science provide insights into how people construct knowledge, with important implications for how we learn from, and teach about, the Earth. Research on learning has demonstrated that effective instructional practices require students to construct their own knowledge bases (i.e. a shift in emphasis from teaching to learning), address diverse student learning styles, employ a variety of active-learning strategies, and encourage inquiry and discovery. These emerging principles provide a context for us to reflect collectively on what and how we teach in our mineralogy, petrology, and geochemistry courses. If we are to meet the challenges of the 21st century, our new instructional goal should be to develop students who are lifelong learners and who use the knowledge base, technical skills, and cognitive strategies that are used by “master” geoscientists. As a result, we will help sustain the long-term health and relevance of the mineralogy, petrology, and geochemistry community

December 2025 --The Variscan Orogeny in Europe – Understanding Supercontinent Formation

The Variscan orogen formed between 380 and 300 million years ago through several accretionary and collisional cycles, culminating with the construction of the Pangea supercontinent. This process occurred via sequential opening and closure of oceanic basins, synchronous detachment of Gondwana derived continental ribbons, and their outboard amalgamation onto the Laurussia margin. The Variscan orogen is rather unique compared with other orogenic belts on Earth: its overthickened and dominantly magmatic crust in the central belt, surprisingly minor mantle involvement in the magmatic and geodynamic processes, coherent and pulsed magmatism along the collision suture, and its complex accretionary history. Because its final product, Pangea, is the youngest and best-understood supercontinent on Earth, the Variscan orogeny offers clues for understanding the mechanisms of supercontinent formation.
