Seppo is an innovation that was made by Finnish teachers. It was truly designed with a focus on pedagogy first and technology second. Ease of use was one of the cornerstones of creating Seppo: using the platform requires no particular technical skills from the teacher.
With Seppo existing games can easily be modified, copied and shared. This makes teaching efficient: you can create learning materials with one colleague and share them with another one. If an exercise needs to be changed or deleted along the way that can be done in a matter of minutes.
