The education system in Bulgaria is extremely outdated. The study material is fairly complicated or taught in an incomprehensible way. Thus, students, especially in upper grade classes, struggle to understand the lessons and stop loving to study at all. Yet it is proven that gamification and picture-based approach help high school students understand even the most complicated stuff. That’s what the free online courses by Khan Academy are doing – they breed love for knowledge by teaching lessons in an understandable way.
