A study on implementation and usage of web based programming assessment system: Code

Abstract

Implementing a web-based system for automatic assessment is a big step in the introductionary programming courses. In this paper we study and report the data generated by the usage of the system Code developed at the Faculty of Computer Science and Engineering. The system supports compilation and execution of programming problems in exercises and exams and it is used in many courses that involve programming assignments. The analyzed data shows the differences in working in laboratory settings, compared to practical exams. We also present the results from plagiarism detection, and report significant cases of plagiarism in introductionary courses. At the end we present the results from initial qualitative evaluation of the system by surveying 48 students.
