Gamification in Education: EcoMUVE . https://ecolearn.gse.harvard.edu/ecoMUVE/design.php. . The goal of the EcoMUVE project is to help students develop a deeper understanding of ecosystems and causal patterns with a curriculum that uses Multi-User Virtual Environments (MUVEs). MUVEs are 3-D virtual worlds that have a look and feel similar to videogames. They are accessed via computers and, in our case, recreate authentic ecological settings within which students explore and collect information.. 11 May 2020 v1. 2 1 Best Practices to Reduce COVID - 19 Transmission Risk As the most sought - after dive professionals in the world, PADI Dive Centers, Resorts and Dive Boats are readying their ope
