In this study, effects of values education on students' attitudes and behaviors on informatics ethics taught in information technologies and software courses have been examined, according to the opinions of information technologies teachers (ITT) working in schools where values education is taught through Selcuklu Values Education Project (SEDEP). This is a qualitative study and in this study, criterion sampling, one of the purposeful sampling methods, have been adopted to determine the participants. Thirty-five information technologies teachers (13 male, 22 female) working in Selcuklu, a district of Konya, have participated in the study. The data have been collected through a fixed format questionnaire form and analyzed using content analysis. The findings show that the values taught in values education are related to informatics ethics in various aspects (individual, family, society, morality, teacher and curriculum). The participants state that the students have been able to transfer the values education to the informatics ethics even if it is not at a sufficient level cognitively and affectively. Participants mainly use values education elements such as respect, responsibility, justice, self-control and empathy, in the teaching of informatics ethics issues (Privacy-Security, Intellectual Property, Cybercrime, and Cyberbullying). The values education elements the participants use to deal with negative behaviors they encounter in relation to informatics ethics are respect, empathy, justice and self-control. Lastly, information technologies teachers have offered some suggestions that can be followed in the classroom and in the digital environment on the use of values education while teaching informatics ethics.
