Why Substitution Isn’t Enough – Rethinking Technology Through the SAMR Lens

It’s surprisingly common for questions about educational tools to spark bigger debates around technology use in the classroom. One question that often crops up goes something like this: “What’s the best app for annotating PDFs on a tablet?” On the surface, it’s a harmless query. But it raises an important point about how technology is being integrated into learning environments.

When digital tools are used simply to replicate what was already being done with pen and paper, we’re often not truly innovating—we’re substituting. And this is where the SAMR model comes in.

A Quick Introduction to the SAMR Model

Developed by Dr. Ruben Puentedura, the SAMR model helps educators assess how technology is being applied to learning tasks. The acronym stands for:

• Substitution – Technology acts as a direct substitute, with no functional change.
• Augmentation – Technology acts as a substitute, but with functional improvements.
• Modification – Technology allows for significant task redesign.
• Redefinition – Technology allows for the creation of new tasks, previously inconceivable.

The higher up the model we go, the more transformative the learning experience becomes.

Why Substitution Often Falls Short

In many cases, educators are handed new tech—such as tablets in a 1:1 classroom setup—only to continue using them in ways that don’t fully utilise their potential. For example, uploading a PDF worksheet and asking students to write over it with their fingers might feel digital, but it’s functionally no different from what was already being done on paper.

This kind of use not only underwhelms learners, but it can also become a barrier to real educational innovation. It fails to take advantage of technology’s ability to automate feedback, support differentiation, and encourage student agency through creative, interactive, and collaborative tools.

Not a Ladder – A Launchpad

There’s a long-standing debate around whether the SAMR model should be seen as a ladder—something to climb step by step—or a barrier to be consciously avoided at its lower levels. Personally, I believe we shouldn’t spend precious professional development time helping educators replicate old practices more efficiently. That reinforces habits rather than challenging them.

If instead we introduce tools that immediately enable redefinition or modification, we not only inspire educators to think differently but also demonstrate the true value of edtech from day one. When teachers see how these tools can create deeper engagement and save time through automation and feedback, they’re far more likely to adopt them meaningfully.

Looking Forward, Not Backward

There’s so much to be excited about in education technology—virtual reality, game-based learning for neurodiverse learners, and augmented reality that brings abstract concepts to life. But to get there, we must stop viewing digital tools as just replacements for what came before.

True progress in edtech starts with asking better questions—not just “what app should I use?” but “how can this tool transform what learning looks like for my students?”
