Students who indicated that they feel uncomfortable when answering questions in front of their fellow students especially profited from the use of the audience response system. Compared are the levels of agreement (mean Likert scale) of those students who indicated that “Answering questions in front of my fellow students makes me feel uncomfortable” (Likert scale 1–3, black bars, n = 48) with the answers of those students who did not agree to this statement (Likert scale 4–6, white bars, n = 64). Students who feel uncomfortable with answering questions in front of others showed a higher level of agreement with the statements “The questions during the seminar will facilitate my preparations for the exam.” (facilitate preparations for the exam, p = 0.034), “eduVote increased my learning success during the seminar.” (increased learning success, p = 0.044), “eduVote motivated me to ask the tutor questions during the seminar.” (motivated to ask questions, p = 0.008), and “I appreciate the anonymity of eduVote.” (appreciate anonymity, p = 0.002). *, p < 0.05; **, p < 0.01; ***, p < 0.005
