Pedagogical Content Knowledge (PCK) refers to the understanding that teachers have of how to effectively teach specific content. It combines knowledge of the subject matter with an awareness of how students learn that subject. This means that a teacher not only knows the content but also understands the best methods and strategies to convey that information to students. PCK is essential for effective teaching because it helps educators anticipate student misconceptions and tailor their instruction accordingly. By integrating content knowledge with pedagogical strategies, teachers can create engaging lessons that facilitate deeper understanding and promote student success in learning.
