In this study, a training was carried out in order to improve pre-service teachers' digital competences with regards to technology integration based on the DigComp framework. In this regard, participants' progress in digital competence and technological pedagogical content knowledge (TPACK) were analysed. In addition, what kind of digital knowledge and skills they utilize in the technology integration process were investigated. As a result, it was found that while pre-service teachers showed progress in the sub-dimensions of TPACK-deep, they made use of their skills in information and data literacy, communication and collaboration, content creation, safety, and problem-solving. In addition, positive correlations were found between digital competences and TPACK competences. Consequently, the roles of digital competences should be considered for successful technology integration.
