This is image documentation of our test-version of the web-app that is used in the game. https://cgl-marsbasen-test.web.app/ (Upon release of the final app, this test-version will become void). Marsbasen is a learning game aimed at high schools, which is specifically developed to teach C-level physics curriculum. In the learning game, students take on the role of a team of pioneers, who are sent to Mars to establish a base. Naturally, this involves a series of scientific challenges, which means that the students must acquire new knowledge, and put that knowledge to good use. Marsbasen is framed by an interactive and partially digital story. Teaching takes place both digitally, in the classroom and doing experiments in the lab. The students experience the game as a progressive story, which they are able to influence. Meanwhile, the goal is to learn physics at C-level.
