Journal of Computer Assisted Learning, Volume 42, Issue 4, August 2026.ABSTRACT Background Teacher agency plays a pivotal role in technology‐enhanced instruction, yet empirical evidence connecting agency to the practical enactment of specific components of TPACK remains limited. In particular, the intersections between teacher agency and TPK/TCK as enacted practices warrant closer scrutiny.
