The aim with this study was to examine how, from the teachers' and students' perspectives, the project-based learning approach was applied in science and technology lessons. The research was conducted through a case study with qualitative research methods. The data of the study were obtained from semi-structured interviews with 38 students and 11 science and technology teachers. This data were analysed by descriptive analysis which is a qualitative data analysis method. The results of this study show that the teachers described the project-based learning approach as an inapplicable approach in schools. Teachers advised a reduction of curriculum content and a reduction in class sizes. We understood that the other phases of the project processes that started with the selection of project topics at school were done with the help of the students' families at home. It also became clear that during the evaluation process, the teachers took the students' own efforts into consideration. We determined that most of the students who participated in the projects in the science and technology course were free to choose their project subjects. It also became clear that students preferred to do projects in the science and technology course. At the end of the research report, suggestions based on the results of the research are made.
