摘要:In this study, a new questionnaire was developed to measure judgmental and behavioral aspects of information ethics by asking students to give responses to questions on unethical uses of ICT tools. Four hundred and thirteen undergraduate students answered the questionnaire. Relationships between measured information ethics and gender, consciousness of everyday ethics, proficiency in ICT tools, and the amount of education received on information ethics were examined and the following results were obtained. Female students were more ethical than male students in both judgmental and behavioral aspects of information ethics. The consciousness of everyday ethics had a strong impact on information ethics. Students who use ICT tools for practical purposes were more ethical than other students. Attending classes on information ethics at university enhanced both aspects of information ethics. Information ethics classes at high school had some effect, but less than that of classes at university. Finally, possible combination effects of everyday ethics, experience in ICT, and the amount of education on information ethics were examined, but no such combination effects were detected by the analysis of variance.
