TPACK triplet

Posted · Add Comment

The TPACK framework seeks to explain the kinds of knowledge teachers need to have to successfully integrate technology in their teaching. The TPACK framework suggests that effective technology integration for teaching specific content or subject matter requires understanding and negotiating the relationships between three key components: Technology (T), Pedagogy (P), and Content (C). A teacher capable of negotiating these relationships represents a form of expertise different from, and (perhaps) broader than, the knowledge of a disciplinary expert (say a scientist or a musician or sociologist), a technology expert (a computer engineer) or an expert at teaching/pedagogy (an experienced educator). More information about the TPACK framework can be found at

Separating the three components (C, P, & T) in the TPACK framework is difficult to tease out in practice. The image below seeks to capture the integrative nature of the relationship between these three components of knowledge through a 3-dimensional shape that throws three different shadows (C, P & T) depending on the light source.
