RT Journal Article SR Electronic A1 Klement, Milan T1 Aspects of the use of proctoring systems in the implementation of mass on-line tests JF e-Pedagogium YR 2024 VO 24 IS 1 SP 7 OP 20 DO 10.5507/epd.2024.004 UL https://e-pedagogium.upol.cz/en/artkey/epd-202401-0001.php AB One of the challenges faced by educational institutions is the integrity of online assessment, i. e. the need to conduct online testing using appropriate tools and methods. Although efficiency and flexibility of deployment is one of the undisputed advantages of online testing, it should be emphasized that online testing using online proctoring systems raises some concerns for participants, which may also have a negative impact on their results. For this reason, using pedagogical research methods and appropriate statistical methods, a research survey was conducted among participants in online placement testing to determine their readiness, but also the specific concerns and expectations that online proctoring brings from their perspective. Both the realization and results of the research are presented in this paper.
