TPACK vs SAMR: Head-to-Head Comparison
TPACK vs SAMR: quick reference
- TPACK: The Blueprint. Focuses on the teacher’s knowledge. Best for planning a new lesson.
- SAMR: The Inspector. Focuses on task design. Best for evaluating or upgrading an existing lesson.
- The synergy: A teacher with strong TPACK can still accidentally design a Substitution-level lesson. Use TPACK to build the foundation, and SAMR to push the depth.
TPACK and SAMR are not competing frameworks. They answer different questions about the same problem: how technology fits into education.
Side-by-side comparison
| Feature | TPACK | SAMR |
|---|---|---|
| Focus | The teacher’s knowledge and skills | The design and impact of the task |
| Components | CK, PK, TK and their overlaps | Substitution, Augmentation, Modification, Redefinition |
| Needs content? | Yes. Collapses without subject matter. | No. Works for any task, including administrative. |
| Best for | Planning a new lesson from scratch | Evaluating or upgrading an existing lesson |
| Analogy | The blueprint for building a house | The inspector checking the quality of the house |
When to use TPACK
Use TPACK in the creation phase:
- Planning a new lesson for a difficult subject
- Training or mentoring a student teacher
- Diagnosing why a technology-rich lesson failed (Was TK weak? Was PK missing? Was CK too shallow?)
TPACK forces you to think about the specific subject. Teaching biology with a graphing calculator makes no sense. Teaching math with Google Earth makes no sense. TPACK catches mismatches between tools and content.
TPACK. You would use it to check if there was a mismatch in the teacher’s knowledge:
- Weak technology skills (TK)?
- Poor teaching methods (PK)?
- Shallow understanding of the math concept (CK)?
TPACK pinpoints which domain broke down.
When to use SAMR
Use SAMR in the evaluation phase:
- Auditing an existing lesson to check whether the technology adds real value
- Evaluating non-instructional tasks like attendance, grading, or parent communication
- Justifying a technology purchase to school administration
SAMR gives you a clear scale. If your lesson is stuck at Substitution, SAMR shows you exactly where to push it.
Using both together
Here is how the two frameworks combine in practice.
Scenario: You want middle school students to understand local environmental pollution.
Step 1, TPACK (build the lesson):
- CK: The local water cycle and common chemical pollutants.
- PK: Project-based, collaborative learning.
- TK: Digital water-testing sensors and data-mapping software.
Step 2, design the activity: Students test water samples from a nearby source and log the results in a digital spreadsheet.
Step 3, SAMR check: This activity is at the Augmentation level. Digital sensors replace paper litmus tests and the spreadsheet auto-calculates, but the task (test and record) is unchanged.
Step 4, push the lesson higher: Revise the task. Instead of logging data for the teacher to grade, students use the data to create an interactive digital map. They publish it on a community website and present it virtually to the local city council. The task moves to Redefinition. It could not happen without the technology.
TPACK gave the lesson a solid foundation: the right content, the right pedagogy, and the right tools. SAMR showed that the first version was stuck at Augmentation and pushed it higher.
TPACK builds the lesson. SAMR checks its depth.
- Use TPACK to define CK, PK, and TK
- Design the activity at their intersection
- Use SAMR to check: is the technology at Substitution, Augmentation, Modification, or Redefinition?
- If the task is at Enhancement, push it toward Transformation
The key difference
TPACK is about the teacher. It asks: “Do I have the right knowledge to design this lesson?” It requires a subject to teach. Without Content Knowledge, TPACK collapses.
SAMR is about the task. It asks: “How is the technology changing what students do?” It works for any task: lessons, assessments, attendance, parent communication.
A teacher with strong TPACK can still design a Substitution-level lesson. A Redefinition-level task can still be taught poorly if the teacher lacks PK. Neither framework alone is enough. Together, they cover the full picture.
