5.9 million children under age five died in 2015, 16 000 every day.

Providing feedback on programming assignments is a tedious task for the instructor, and even impossible in large MOOCs with thousands of students. In this paper, we present a novel technique for automatic feedback generation: (1) For a given programming assignment, we automatically cluster the correct student attempts based on their underlying strategy. From each class we select one student att...
Since 2012, the vision of MOOCs in universities has been evolving rapidly. Universities that have decided to place a serious bet for including this kind of courses in their portfolio have involved a diverse set of staff roles within the institution. In most cases, with the exception of fully dedicated staff members hired for the sole purpose of MOOC development, MOOC related tasks are assigned ...
