In addition, rubric-based measurement tools afford a level of
versatility in terms of what product they can be applied to.
Loughran et al. (2001) note that PCK may not be readily observable
at one single point in time such as during an observation or an
individual lesson. Given that many scholars emphasize the
importance of PCK throughout every portion of a teacher’s
professional practice (Park et al., 2011; Shulman, 1987), then a
PCK measurement tool would ideally be versatile so that it can be
used to measure PCK in planning, implementation, and other
stages of a teachers practice. While other scholars have attempted
to create PCK rubrics, these rubrics are discipline specific (Lee et al.,
2007; Park et al., 2011). The partnership, therefore, has determined
that a STEM PCK rubric should be developed for the measurement
of the STEM PCK outcome. The STEM PCK rubric will be an analytic
rubric with at least one rubric category designed to align to the
three components of STEM PCK in the construct definition
