In this study the views of graduate thesis advisors at Sakarya University, Institute of Educational Sciences (5 Male, 4 Female) are analysed regarding their students' knowledge on scientific research ethics (SRE). This was done via phenomenology, one of the qualitative research methods. The data were collected with structured interview questions and also additional probe questions when needed. The questions were written by the researchers after performing a comprehensive literature study. Expert opinions were asked for after the interview form was prepared. The experts evaluated the suitability of the questions in terms of scope and language and found them to be sufficient. Moreover, three advisors were chosen randomly among the target group to be asked the questions in order to check clarity and expediency before data collection. The findings of the research showed that knowledge about the SRE of most of the students was insufficient, and the educational need for this matter was provided by the advisors. It was also reported by the advisors that most of the students' knowledge about the SRE was learnt by direct experiences while preparing their thesis and their levels of awareness about the importance of the subject were very low before the thesis stage. The advisors also mentioned that the curricula do not directly include a course on the scientific research ethics; a limited content is taught within the research methods course. It was stated that real life cases, examples and experiences might be effective in enhancing students' awareness levels regarding the SRE. Developing empathy was mentioned as an important technique for creating awareness. Consequently it is thought that taking the findings of this study into account may improve students' levels of awareness on codes of ethics. Research teams could be created within universities and they could focus on providing research and writing support to the students who are at thesis stage. Regarding systematic approach, the awareness regarding plagiarism should be increased from the undergraduate level to post graduate studies.
