High-Coverage Hint Generation for Massive Courses
Phitchaya Mangpo Phothilimthana, Sumukh Sridhara · 2017
In massive programming courses, automated hint generation offers the promise of zero-cost, zero-latency assistance for students who are struggling to make progress on solving a program. While a more robust hint generation approach based on path construction requires tremendous engineering effort to build, another easier-to-build approach based on program mutations suffers from low coverage.
