Young people are increasingly engaging in contacts via social media. Although this activity is primarily a form of entertainment, students also treat social media as a learning-supporting tool. The aim of the studies presented in this paper was to determine whether using Facebook as an e-learning platform brings satisfying academic performance. Additionally, the application of the gamification feature was examined. Two quasi-experiments were conducted in which some of the subjects took part in traditional classes, while others participated in asynchronous classes conducted on social media. The results of the first experiment demonstrated that a Facebook-run e-learning course contributed to higher grades, while the second experiment showed the opposite effect. Gamification had a neutral or negative impact on the grades. The results are discussed in the context of differences between the designs of the two Facebook courses. The paper makes suggestions for future SNS-based or SNS-assisted classes. It is proposed to use informational feedback instead of a controlling one. Additionally, the use of team work is encouraged. The discussion includes a reflection on students’ autonomy.
