This research aimed to determine the opinions of preservice teachers on the use of technology in education and the preparation of technological materials for teaching purposes regarding stop-motion applications. The research was organized according to the qualitative research paradigm and designed according to the basic qualitative research model. Research data were collected with an opinion form developed by the researchers through face -to-face interviews with teacher candidates after the implementation process. Afterwards, descriptive analysis was performed and frequency and percentage calculations were conducted. The research was carried out with 24 teacher candidates in their second year of study in the Kırşehir Ahi Evran University Faculty of Education’s Department of Primary Education in the 2019-2020 academic year. According to the findings, with stop-motion applications, preservice teachers teach how to work in groups, provide learning proficiency, combine thoughts, provide cooperation, create different ideas, take responsibility, provide permanent learning, make common decisions, realize mistakes, understand the subject better, and conduct research. They expressed positive opinions within the framework of the considered themes, although female participants stated that they had more problems while preparing stop-motion applications than male participants.
