With 2.7 million users around the world and 3 billion records of data related to student activity, the edX platform is “a particle accelerator for learning”. That is what the president of edX, Anant Agarwal, said during the LinuxCon conference in Chicago.
“We can learn how students learn by mining the big data of learning”. For instance, the big data analysis found that between 6 and 9 minutes is the ideal length of time for an educational video. Anything longer and students begin to drop off.
