MegaMinds is a social learning platform for K-12 that leverages virtual worlds, 3D teaching tools, and powerful presentation abilities to empower teachers and engage young minds. The platform enhances classroom and online learning through the experiential and collaborative nature of virtual world gameplay. It enables teachers to easily take their existing presentations and place them in interactive 3D worlds to engage students and increase active classroom participation. Mega Minds is entirely browser-based, requiring no software installation or additional hardware. It is an all-in-one solution designed for both synchronous and asynchronous use with low-powered computing devices both in-person and remotely. We believe our platform can be a powerful tool in democratizing access to education, enabling students to access content and interact with teachers and peers in ways that would often be limited by geography, finances, or venue capacity.
