From conceptual foundations to enacted PCK: a mixed-methods study with primary teachers teaching the human body

This study examines how teachers’ Conceptual Knowledge (CK) relates to both their personal and enacted PCK among 13 in-service primary school teachers teaching the human body. An explanatory sequential mixed-methods design was employed, combining a CK test, an analytic PCK rubric, and pre- and post-lesson interviews supported by classroom video recordings.

Results revealed a low correlation between CK and PCK, suggesting that they are distinct yet interrelated constructs. However, a functional conceptual threshold was identified, beyond which teachers were able to enact more coherent and scientifically grounded PCK. The qualitative analysis uncovered different patterns of CK–PCK articulation, ranging from routine-based strategies to reflective practices aimed at promoting students’ conceptual understanding.
