    Plagiarism Detection Approaches for Simple Introductory Programming Assignments
    (Proceedings of the Fifth Workshop "Automatische Bewertung von Programmieraufgaben" (ABP 2021),virtual event, October 28-29, 2021, 2021) Strickroth, Sven
    Learning to program is often perceived as hard by students and some students try to cheat. Plagiarisms are reported to be a huge problem particularly for summative-like assignments (e.g., crediting courses or bonus points). It is important to fight plagiarisms from early on – even for simple assignments. Especially for larger courses tool support is required. This paper provides an overview of features for commonly used plagiarism detection tools, discusses how these can be integrated into existing assessment systems, and how their results relate to each other for two data sets of quite simple assignments. Additionally, these specialized tools are compared with a simple Levenshtein distance approach. The paper also outlines limits on very simple assignments.

    Security Considerations for Java Graders
    (Proceedings of the Fourth Workshop "Automatische Bewertung von Programmieraufgaben" (ABP 2019), Essen, Germany, October 8-9, 2019, 2019) Strickroth, Sven
    Dynamic testing of student submitted solutions in evaluation systems requires the automatic compilation and execution of untrusted code. Since the code is usually written by beginners it can contain potentially harmful programming mistakes. However, the code can also be deliberately malicious in order to cheat or even cause damage to the grader. Therefore, it is necessary to run it in a secured environment. This article analyzes possible threats for graders which process Java code and points out Java specific aspects to consider when processing untrusted code.
