	abstract = {The unexpected challenges posed by the pandemic also have transformed university education. Information technology is still the most advantageous field, as IT tools in education are more widespread. We have been using the ProgCont system for automatic evaluation of programming tasks since 2011 at the Faculty of Informatics of the University of Debrecen. The system’s responsibilities have expanded over the years, and due to the pandemic, it will have to play a more significant role in self-preparation. Initially, we used the system to evaluate competitive tasks and later examinations. In this period, the feedback was limited to accepting or rejecting the submitted solutions.  A submitted solution is accepted if the application produces the appropriate output for the problem’s input. Usually, we test the submissions with several inputs (test cases) for each problem. To provide additional information about the reason for rejection, we would like to supplement test cases with comments (annotations) that identify the test cases’ unique properties. Our goal is to help identify the subproblems that need improvement in case of a partially correct solution. In our article, we would like to present the potential of this development. We chose a problem that received an impressive number of solutions.  We created new test cases for the problem with annotations, and by re-evaluating the submissions, we compared how much extra information students and instructors obtained using the annotations. The presented example proves that this new development direction is necessary for students’ self-preparation and increases differentiated education possibilities.},

A complex IT problem solution is inconceivable without adequate mathematical background knowledge. In our research, we would like to show this connection through the analysis of programming tasks, for which we use the automatic solution evaluation system developed by the Faculty of Informatics of the University of Debrecen almost a decade ago and the data accumulated during its use. We examine the effectiveness of users in solving programming tasks that require mathematical and IT knowledge, compare performance in different programming languages, and look for topics where improvement is needed. The results show that, contrary to our expectations, students perform better on tasks that require both mathematics and informatics skills.},

Több mint egy évtizedes múltra viszszatekintő ProgCont rendszerünkben is szükségessé vált, hogy reagáljunk az ebből adódó kihívásokra. Az önálló felkészülést azzal kívántuk segíteni, hogy javítjuk a rendszer automatikus visszajelzéseit, olyan új annotációkkal ellátva a kitűzött feladatok részfeladatait, melyek segítenek a részben jó megoldásokban fellelhető hibák feltárásában. Cikkünkben bemutatjuk az annotációk kialakításának útját, három különböző felhasználási területet alapul véve, és összefoglaljuk az új technikának köszönhető tapasztalatokat és eredményeket.},

Our previous studies have shown that enhancing the system’s feedback can play an essential role in this respect, for which we have developed an annotation technique. Our paper focuses our investigations on mathability, examining students’ performance in solving tasks that require mathematical skills, using the possibilities offered by annotations.},
