Learning or doing ones homework isn’t among the first things students like to do. They rather play videogames — a situation every teacher knows. One chance to solve this problem is to combine learning and video games. Scientists are discussing game-based learning and gamification in this context. To shed some light at the meaning of these terms, especially on gamification, is one of the purposes of this thesis. Gamification doesn’t mean to cover boring learning content with some sort of game mechanics or to reward a right answer with a minigame, that has no connection to the teaching and learning content at all. In contrast, gamification is the inclusion of game elements in learning applications to motivate students to use these applications to learn. Learning languages takes special profit of computer-assisted learning. Using an online learning environment enables the students to get in touch with each other and exchange experiences. Certain game elements can be used to let students participate in a sort of competition. Here they can compare their knowledge in a game-based manner. In the context of this thesis, a prototype will be developed that connects game elements to a learning application for “German as a Foreign Language“. The purpose of this prototype is to show teachers possibilites to motivate their students. A usability test will be conducted, the collected data will be evaluated and improvements will be proposed. As a result of this thesis, it is shown that the prototype includes promising approches and was evaluated successfully. Nonetheless the prototype needs to be tested more thoroughly and improvements need to be implemented. Furthermore, evaluation methods need to be developed to take the peculiarities of games and their special characteristics into account.
