What is TPACK
TPACK framework breakdown
- CK (Content): The “What” (subject matter mastery).
- PK (Pedagogy): The “How” (teaching methods and classroom management).
- TK (Technology): The “Tools” (digital fluency and hardware skills).
- PCK: Best teaching strategy for a specific subject.
- TCK: How technology visually represents or changes a subject.
- TPK: How technology transforms teaching methods overall.
- TPACK: The center. Seamless blending of all three.
TPACK stands for Technological Pedagogical Content Knowledge. It is a framework that identifies the types of knowledge a teacher needs to integrate technology into their teaching. It is built on three core areas and the overlaps between them.
Picture three overlapping circles in a Venn diagram. Each circle is one type of knowledge. Where any two circles overlap, a new type appears. The center, where all three overlap, is TPACK itself.
Technological Pedagogical Content Knowledge
The knowledge of how to teach a specific subject, using the right teaching methods, with the right technology.
- Where all three circles of the Venn diagram overlap
- The technology feels invisible when CK, PK, and TK align well
The three core knowledge areas
Content Knowledge (CK)
CK is your mastery of the subject you teach. In a B.Ed. program, courses like Content Area Studies in General Science or Foundations of Social Studies build this area.
- Understanding Newton’s Laws of Motion in physics
- Knowing the causes and effects of World War II in history
- Mastering differential calculus in mathematics
You cannot teach what you do not understand. A weak CK shows up the moment a student asks a question you did not expect.
Pedagogical Knowledge (PK)
PK is your expertise in how people learn and how to teach them. Courses like Educational Psychology, Child Development, and Classroom Management build this area.
- Using scaffolding to break a difficult reading assignment into smaller steps
- Giving exit tickets at the end of class to check understanding
- Using differentiated instruction to teach fast and slow learners in the same room
PK works across subjects. These strategies apply whether you teach English or chemistry.
Technological Knowledge (TK)
TK is your ability to use digital tools. Courses like ICT in Education focus on this area.
- Operating a multimedia projector or interactive whiteboard
- Navigating a Learning Management System like Google Classroom or Moodle
- Creating a digital presentation or editing a short video
TK also includes the ability to learn new tools as they appear. Specific software changes every few years, but the skill of picking up new technology stays with you.
The ability to learn new technologies.
TK is not just about knowing today’s software. It includes the adaptability to learn new digital tools as they continuously evolve. Specific platforms change every few years, but the skill of picking up new technology stays with you.
The three intersecting domains
When the core areas overlap, they create three specialized types of knowledge.
Pedagogical Content Knowledge (PCK)
PCK is the overlap of how you teach and what you teach. It is the knowledge of the best teaching strategy for a specific subject.
- In mathematics: knowing that students struggle with fractions, so using pie charts and manipulatives instead of abstract formulas
- In literature: running a Socratic Seminar for student-led debate about a novel’s moral questions
- In science: addressing the misconception that heavier objects fall faster by having students drop objects of different weights
Technological Content Knowledge (TCK)
TCK is the overlap of your tools and your subject. It is knowing how technology can represent your subject in ways that were not possible before.
- In geography: using Google Earth to explore tectonic plates in 3D instead of a flat textbook map
- In history: accessing digital museum archives so students can examine historical artifacts up close
- In mathematics: using Desmos to show how changing a variable alters the shape of a graph
Technological Pedagogical Knowledge (TPK)
TPK is the overlap of your tools and your teaching methods. It is knowing how technology changes the way you teach, regardless of the subject.
- Using Kahoot or Quizizz for formative assessment, turning a quiet paper quiz into a gamified activity
- Using breakout rooms in Zoom for small-group collaboration during online classes
- Setting up an asynchronous discussion board where shy students can contribute without speaking up in class
PCK, TCK, and TPK
- PCK (Pedagogical Content Knowledge): the best teaching strategy for a specific subject
- TCK (Technological Content Knowledge): how technology represents or changes a subject
- TPK (Technological Pedagogical Knowledge): how technology changes teaching methods, regardless of subject
The center: TPACK
TPACK is where all three circles overlap. It is the knowledge of how to teach a specific subject, using the right teaching methods, with the right technology. When all three align, the technology feels invisible. Students focus on the learning, not the tool.
A literature teacher wants students to analyze characters in a novel. Instead of assigning a traditional essay, the teacher has students co-author a character analysis on Google Docs in real time. The teacher watches the document live and uses the comment feature to give feedback on both the writing process and the understanding of the text. Google Docs (TK) supports collaborative writing with live feedback (PK) to teach literary analysis (CK). That is TPACK.
Each of the seven domains has a distinct scope. Make sure you can tell them apart.
