The present study aims to determine the relation between Technological Pedagogical Content Knowledge (TPACK) levels of teachers and their self-efficacy in integrating technology, their technology literacy and their usage objective of social networks. Structural equation modeling was utilized to create a model explaining and predicting the relations. The study group consisted of 401 teachers. The relational screening model was applied in this study. In the model which was reviewed in the light of obtained study results, it was detected that the most significant variable in the prediction of TPACK levels of teachers' was teachers' technology integration self-efficacy. From this, it can be argued that in teacher education for achieving effective technology integration, it may be useful to explicitly encourage teachers' own beliefs and focusing on developing their own beliefs in practices for technology integration.
