Gameful Learning for a More Sustainable World Measuring the Effect of Design Elements on Long-Term Learning Outcomes in Correct Waste Sorting

Greta Hoffmann, Jella Pfeiffer
This study investigates the effectiveness of using a mobile game app to teach correct municipal waste sorting. In a laboratory experiment, researchers compared the learning outcomes of participants who used the game with a control group that used standard, non-game educational materials. The study also specifically analyzed the impact of two game design elements, repetition and a look-up feature, on long-term knowledge retention and real-world application.

Problem Effective municipal waste sorting is a critical component of sustainability efforts, but many citizens lack the knowledge to do it correctly. Existing educational resources, such as paper-based flyers, are often ineffective for transmitting the large amount of information needed for long-term behavioral change, creating a gap in public education that hinders recycling efficiency.

Outcome - Game-based learning significantly enhanced waste sorting knowledge across all tested measures (in-game, multiple-choice, and real-life sorting) compared to traditional paper-based materials.
- The game successfully transferred learning to a real-life sorting task, a result that has been difficult to achieve in similar studies.
- The 'look-up' feature within the game was identified as a particularly promising and effective design element for improving learning outcomes.
- The combination of 'repetition' and 'look-up' game mechanics resulted in significantly higher learning outcomes, especially within the digital testing environments.
