Perceived quality of Verifìcator in teaching programming
Tutor is part of a C++ learning programming interface named Verificator. It explains to students the causes of syntactic and certain logical incorrectness in their programs. In order to be helpful, tutor messages need to be more intuitive and clear in relation to the existing compiler error messages and warnings. The research presented in this paper analyses the frequencies of different kinds of error-related messages in students ' programs, as well as their mutual correlations. It has been shown that tutor messages are more strongly related to error messages than to standard compiler warnings.
