Abstract
One of the most important components of distance learning for software developers is practice. For effective learning and scaling, an instructor needs to check student’s code automatically. This paper presents an actual overview of the present state of online e-learning platforms, Massive Open Online Courses (MOOCs), and other online learning services and solutions with automatic checking of students’ practical assignments. It also provides an extensive theoretical framework for automatic compilation, code validation, architecture, scalability, and fault tolerance.
