After a successful pilot project using busuu, we tested the chosen language learning application’s effectiveness with learners of four languages (German, English, Spanish, Italian) (n=94) using pre and post language tests. According to the language test results, the experimental group increased their performance (+2.2%) while the control group’s performance decreased (-3.1%) and the difference in post-measurement was statistically significant (p=.013). Shortly after this, we tested Lifeline, a text-based interactive sci-fi story, which combines reading with a game. The students’ feedbacks show that they found the app very motivating and exciting. Further research will focus on the effectiveness of Lifeline in language learning.
