Twenty Years Later: Does pedagogical content knowledge remain a useful idea?
Abstract
This paper considers how the notion of pedagogical content knowledge (PCK) has developed and changed over the past 20 years. It draws on the preceding papers in this special issue to reflect on the big picture issues and ideas that are important in shaping understandings of PCK and the nature of research on PCK. The paper is structured around four sections. The first section offers analysis of the characteristics of PCK as employed by the researchers in this volume, raising some issues related to the construct. The second section considers the implications for research design that result from these authors’ views of PCK. The third section suggests an agenda for future research on science teacher knowledge. The concluding section examines the continuing value of the PCK construct for the science education community.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
