NavApps is an education game fostering spatial literacy for secondary school students, particularly related to navigation and wayfinding abilities. Pupils can use NavApps to improve wayfinding, distance and angle estimation, route-following, and travel-planning competencies. Teachers can use NavApps to consolidate pupils ICT knowledge, and more importantly, help them improve their spatial feeling, orientation skills, map reading ability, while reinforcing learning concepts from their curriculum (e.g., concepts stemming from geometry, geography, mathematics). But above all, NavApps is fun! Find treasures, score points, compete with your classmates, and become the king of your school!
