Management and assessment of homework assignments in programming courses is a challenging topic both for researchers and practitioners. In the current paper we propose a solution based on the blending of automated evaluation and peer learning. More specifically, we introduce a platform called Q2A-I, which provides two main features: (1) automated management and assessment of homework submissions; and (2) peer interaction support on the programming tasks, by exchanging questions and answers through dedicated micro-forums.

Automated assessment and feedback of computer programming tasks can be a significant asset in computer science education. Web based systems providing such capabilities are designed to apply techniques ranging from static analysis of program correctness, to testing-based evaluation, and often can have application in frameworks supporting competitive programming. Here we report on the 2TSW system, which uses the testing-based approach in a gamified web-based environment. In 2TSWa learner can access a list of assignments, submit solutions and have such solutions tested and graded.
