This research examines junior high school social studies teachers' technology pedagogy content knowledge (TPACK) and how this knowledge influences acceptance of technology in online teaching and learning. In this study, the quantity approach was applied, while the type of research is descriptive explanatory. A total of 875 social science teachers were surveyed in East Java Province. Structural Equation Modelling (SEM) with AMOS version 20 software was used during data analysis. Perceived utility (PU) and perceived ease of use (PEU) are highly impacted by TPACK. Moreover, PEU substantially affects PU, which has been demonstrated to impact behavioural intention to use (BIU) and an attitude toward use (ATU) significantly. As a result, TPACK is essential to adopting online teaching and learning, and its PU is crucial to instructors' attitudes regarding and continuous use of it. It is possible that the characteristics of this sample do not accurately reflect Indonesian social science educators. Research on the potential effects of additional variables, like self-efficacy or social science teacher performance, would be interesting. The integration of TPACK and TAM is examined in this study to generate a conceptual framework based on empirical data.
