The current study aims to determine the opinions of gifted students and prospective teachers attending a nature education program based on a mentoring approach regarding the education process in which they take part together as mentors and mentees. Throughout the project, the activities were carried out in groups of four consisting of two gifted students and two prospective teachers. The study was carried out according to the case study pattern which is one of the qualitative research methods. The study included a total of 32 participants: 16 eight graders (7 females, 9 males) and 16 fourth class prospective teachers (11 females, 5 males). To collect data, two tools were employed in the study: the open-ended questionnaire prepared by the researchers and the diaries in which the participants wrote about what they felt and thought about each day during the project. Data were analyzed by content analysis. Examining prospective teachers' answers to open-ended questions, they perceive socially positive their participation in the project together with the gifted students and emphasize the need to carry out future studies "to be able to be aware of them". Examining the opinions of the gifted students, on the other hand, similarly, they all stated positive opinions. Furthermore, when we look at students' responses at the end of the project and their responses at the beginning of the project, we can see that they emphasize the social outcomes of the project more. Moreover, an examination of the diaries of the prospective teachers revealed that the "Realizing weaknesses", "Learning new information" and "Fun" were the codes that were most repeated for the prospective teachers while "Pleasing", "Very nice" and "Fun" for the gifted students. In this respect, we can argue that both target groups feel positive about participating in future projects together.
