Grasple helps educators around the world to collaborate and build on top of each other’s work to create high quality open online exercises on math and statistics.
Already, more than 30.000 students have already answered over 12 million exercises at Grasple. Grasple is a social enterprise that partners with many universities, such as UvA, HvA, Delft University of Technology and Utrecht University, to release open exercises. What makes their model unique is that all materials have an open source license and are, without login, accessible to everyone.
For this they have recently been awarded the Open Education Award for Excellence 2019 by the OEC, an international consortium of universities, such as MIT and many others.
