The document discusses Technological Pedagogical Content Knowledge (TPACK), which is a framework that describes how teachers effectively integrate technology, pedagogy, and content knowledge. TPACK addresses a teacher's mastery of content knowledge, pedagogical knowledge, and technological knowledge. Specifically, content knowledge refers to a deep understanding of the subject matter being taught. Pedagogical knowledge involves understanding how to teach and manage instruction. Technological knowledge means understanding how to use technology to enhance learning. TPACK is about combining these three areas of knowledge to assist teaching.
