Veronica Boix Mansilla, cofounder of the Interdisciplinary Studies Project at Project Zero, explains "when [students] can bring together concepts, methods, or languages from two or more disciplines or established areas of expertise in order to explain a phenomenon, solve a problem, create a product, or raise a new question" they are demonstrating interdisciplinary understanding. For over a decade, Project Zero researchers at the Harvard Graduate School of Education have been studying interdisciplinary work across a range of settings. They have found interdisciplinary understanding to be crucial for modern-thinking students.[2] Developing a cognitive and social model of interdisciplinary learning is still a challenge.
