Pedagogical Content Knowledge Development in Novice versus Expert Mathematics Teachers
Quick fact
Research by Lee Shulman (1986) introduced pedagogical content knowledge, and studies show that expert mathematics teachers possess more integrated, flexible PCK, enabling them to anticipate student misconceptions and adapt instruction in real time, whereas novices struggle to do so.
