Pedagogical Content Knowledge (PCK) is exactly the kind of PD teachers need, but is often missing because it is so personalized. PCK refers to how to apply pedagogical strategies to the specific content knowledge their students are learning. Often teachers have training in many pedagogical strategies and are familiar with the content they need to teach, but lack the PCK needed to connect those pedagogical strategies to the content on a practical day-to-day basis.
