Gamification and social networking can be used as active learning tools, as they have been shown to increase learner motivation. Nevertheless, it is unclear whether they impact students' knowledge acquisition. This study aimed to share an educational experience for medical students using Kahoot and TikTok as active teaching/learning tools and assessed whether they improve academic performance. A retrospective quasi-experimental study was conducted with 176 students enrolled in radiation oncology in the 2021/22 academic year (control group), who received traditional teaching, and 166 students in the 2022/23 academic year (experimental group), where Kahoot and TikTok were added to traditional teaching. Final exam results of both groups were compared to assess learning differences, as well as those of the experimental group in terms of participation in Kahoot and TikTok and their relationship with the final grade. Comparing the average exam scores of the experimental group to the control group showed an increase of 12.9% in the first group compared to the traditional group (6.02 vs. 7.31 points, p = 0.0001). In the experimental group, students who participated in Kahoot or TikTok increased their mean score by 0.54 points (p = 0.021) and 1.57 points (p = 0.040), respectively, compared to those who did not. A correlated increase in mean test scores was observed based on tool usage: none, Kahoot or TikTok, or both (6.19, 6.88 ± 1.48, and 7.51 ± 1.20 points, p = 0.019). Using Kahoot and TikTok as active learning tools for medical students improved academic performance when integrated with traditional methodology.
