Educating Youth About Human Impact on Freshwater Ecosystems Using an Online Serious Game

Abstract

Freshwater ecosystems are among the most biodiverse ecosystems on the planet and constitute key natural resources for human economies. These ecosystems, however, are endangered due to persistent human activities, ranging from temperature changes to water pollution. Here, we develop an online serious game to educate youth regarding human impact on freshwater ecosystems. In particular, we focus on how environmental variables can affect the behavior and well-being of freshwater fish, which are critical to the food web and the function of the whole ecosystem. In the game, players aim to maximize fish fitness by foraging and reproducing, despite adversarial environmental conditions. We leverage dynamical systems theory to create mathematical models for all the game characters and components, including animal locomotion and hydrodynamic interactions with the flow physics of a virtual river. We test the educational value and usability of the game on a group of middle-school students from New York City. Our results suggest that games like the proposed serious game could be a viable tool to engage youth in environmental education about freshwater ecosystems.
