When SAMR Fails and TPACK Works
When SAMR fails and TPACK works
- The problem: A lesson can reach Redefinition on SAMR but still teach nothing.
- SAMR’s blind spot: It measures the task, not the teaching or the content accuracy.
- TPACK’s strength: It checks all three domains (CK, PK, TK). If any domain is weak, the framework exposes it.
- The rule: High-level technology cannot compensate for bad pedagogy or shallow content knowledge.
The previous article showed a case where TPACK fails and SAMR works (attendance has no content, so TPACK collapses). This article shows the opposite: a lesson that scores perfectly on SAMR but is a complete failure in practice. TPACK is the only framework that catches it.
The scenario: the flashy science podcast
A middle school science teacher wants students to learn the laws of thermodynamics. The teacher decides to have students create a podcast. Students must interview people online, edit the audio, add music, and publish the finished episode to a public platform.
There is a problem. The teacher does not understand thermodynamics well. Because of this, the teacher gives vague instructions: “Go research it online and make the podcast.” There is no rubric. There is no step-by-step guide. There is no check to see if the students’ science facts are correct.
The students produce a polished, professional-sounding podcast. The audio quality is excellent. The music is well-chosen. The episode is published online for the world to hear.
The science in the episode is wrong.
A lesson that reaches the Redefinition level on SAMR (the technology creates a task that was previously impossible) but produces zero actual learning.
The technology is impressive. The task looks transformative. But the content is wrong and the pedagogy is missing.
Why SAMR gives this lesson a high score
If a school principal evaluates this lesson using SAMR, the result looks impressive.
The task moved from a standard written essay (Substitution) to a globally published, interactive audio production (Redefinition). Students recorded interviews, edited audio, and published for a real audience. By SAMR’s measure, the technology completely transformed the task.
SAMR gives this lesson its highest rating: Redefinition.
The problem is that SAMR only measures the task. It does not check whether the teacher taught well. It does not check whether the content is accurate. SAMR is “pedagogy-blind” and “content-blind.” A beautifully produced podcast full of wrong science facts still counts as Redefinition.
Why TPACK catches the problem
If an instructional coach evaluates the same lesson using TPACK, the failure is obvious. TPACK checks all three knowledge domains.
- TK (Technological Knowledge): High. The teacher knows how to use podcasting software and publishing platforms. No issues here.
- PK (Pedagogical Knowledge): Low. The teacher gave no scaffolding, no rubric, and no formative assessment to guide students through the research process. Students were left to figure it out on their own.
- CK (Content Knowledge): Low. The teacher does not understand thermodynamics well enough to review the students’ scripts for accuracy. Wrong facts went uncorrected.
The center of the Venn diagram is empty. TK is strong, but PK and CK are weak. Without all three domains working together, the lesson is broken. TPACK exposes exactly where it broke and why.
TK is high (the teacher knows podcasting tools), but PK is low (no rubric, no scaffolding, no formative assessment) and CK is low (the teacher cannot verify the science).
The center of the Venn diagram is empty. High-level technology cannot fix bad pedagogy or shallow content knowledge.
What this tells us about the frameworks
SAMR assumes the teacher already knows how to teach. It assumes the content and pedagogy are solid, and it just measures the technology’s impact on the task. When the teaching is weak, SAMR accidentally rewards a bad lesson because it looks futuristic.
TPACK keeps educators grounded. It checks all three areas. A podcast about thermodynamics is useless if the physics is wrong. A VR field trip is useless if students have no guidance on what to observe. Technology at the Redefinition level does not guarantee learning at any level.
The previous article showed that TPACK has a blind spot (it cannot evaluate tasks without content). This article shows that SAMR has a blind spot too (it cannot evaluate whether the teaching or the content is any good). Neither framework alone gives you the full picture. You need both.
