Seppo is a unique tool that helps teachers to gamify their lesson plans. Seppo combines gamification, social learning, digital storytelling and physical movement. Gamification motivates students and increased engagement makes learning more efficient. Seppo can be used for any school subject at any school level, for onsite and online learning. The teacher creates the game and the exercises from scratch or by using materials from the vast content library. Students then login into the game on their mobile devices. The teacher monitors the game giving students personalized feedback and points. Seppo games allow students to practice 21st century skills such as creative problem solving and digital storytelling: the exercises can be answered by video, audio, text and photos.. Seppo games also enhance collaboration skills as they are usually played in teams. Students can also design their own games. The games can be played indoors or outdoors.
