The game is the learning experience itself
The key to game-based learning is that the player must take action to progress and receives immediate feedback on their actions.
Interactivity requires you to stay focused and pay attention at all times, as well as to evaluate your own choices along the way.
Here, prior knowledge gained from the game may need to be evaluated in the context of new challenges in order to move forward. Research in digital learning shows that students become more engaged and learn better when the content is interactive and can be adapted to different target groups.
