From this perspective, it is significant to integrate SSI in educational programs to educate scientific literate citizens who have critical thinking skills and make informed decisions. Teaching SSI to science teachers and biology teachers come into prominence more than other majors regarding their impact on students and the content of the curriculum. The purpose of this research, thus, was to identify how biology teachers performed SSI education with students and what they needed in this regard. In this study, a phenomenology study, one of the qualitative research designs was used. The study group consisted of fourteen biology teachers (9 females and 5 males) working in different cities in Turkey in the fall semester of the 2017-2018 academic year. The data were obtained through face-to-face semi-structured interviews, telephone and internet calls (facetime and skype) using a data collection tool comprising six open-ended questions which were prepared by the researchers. To analyze the data, codes and themes were developed through content analysis method. The transcription, coding, and analysis of the interviews were conducted independently by two of the researchers in this study. According to the obtained results, it was identified that teachers are in need of support in terms of the definition of SSI, teaching method and technique, subject content details, and teaching materials.
