The SAMR model considers four levels of integration: substitution, augmentation, modification, and redefinition. The TPACK model addresses the interaction of technological, pedagogical, and content knowledge and how they relate to teaching in a technology-enhanced learning environment.

The SAMR model was created by Ruben Puentedura, and provides some context for assessing the quality of the technology task that we integrate into learning. 

The last stage of the SAMR model is Redefinition and represents the pinnacle of how technology can transform a student’s experience. In this case, you ask yourself if the technology tools allow educators to redefine a traditional task in a way that would not be possible without the tech, creating a novel experience.

At this stage, technology is directly substituted for a more traditional one. It is a simple, bare-bones, direct replacement.

Assistant Principal Share SAMR Model: A Practical Guide for EdTech Integration Posted in Pro Tips | October 30, 2017 Share The SAMR Model is a framework created by Dr. Ruben Puentedura that categorizes four different degrees of classroom technology integration. The letters "SAMR" stand for Substitution, Augmentation, Modification, and Redefinition. The SAMR model was created to share a common language across disciplines as teachers strive to help students visualize complex concepts. Image Modified from Original by Lefflerd’s on Wikimedia Commons While it’s often visualized as a ladder or staircase as above, this can be misleading because Substitution (the bottom of the ladder) is sometimes the best choice for a particular lesson. This is why it’s better to think of the SAMR model more as a spectrum. On one end technology is used as a one-to-one replacement for traditional tools, and on the other end technology enables experiences that were previously impossible without it.

The SAMR Model Explained (with Examples) The SAMR model is made up of four steps—Substitution, Augmentation, Modification, and Redefinition. Substitution and Augmentation are considered "Enhancement" steps, while Modification and Redefinition are termed "Transformation" steps. Think of the difference between seasoning an old family recipe (Enhancement) and creating an entirely new, original dish (Transformation). Susan Oxnevad referred to this movement across the spectrum as "teaching above the line." Substitution At this stage, technology is directly substituted for a more traditional one. It is a simple, bare-bones, direct replacement. For example, if you are teaching a government lesson on the Constitution, you might use an electronic or web-based version of the document instead of a hard copy. Students might also answer questions about the Constitution using a Microsoft Word instead of filling out a worksheet. Substitution might also include a student using Keynote, PowerPoint, Prezi, Slides, or a similar program to present information about an article or amendment to the class. In this step, you ask yourself what we stand to gain by replacing traditional tools with technology. Invariably, some situations will be better served with pen and paper.

Augmentation The technology is again directly substituted for a traditional one, but with significant enhancements to the student experience. In other words, you ask yourself if the technology increases or augments a student's productivity and potential in some way.

beginning to move from enhancement to transformation on the model. Instead of replacement or enhancement, this is an actual change to the design of the lesson and its learning outcome. The key question here—does the technology significantly alter the task?

a group of students might collaborate in a cloud-based workspace to propose a modern definition of equal protection under the law and solicit feedback on their proposals from classmates.

The SAMR model is made up of four steps—Substitution, Augmentation, Modification, and Redefinition. Substitution and Augmentation are considered "Enhancement" steps, while Modification and Redefinition are termed "Transformation" steps. Think of the difference between seasoning an old family recipe (Enhancement) and creating an entirely new, original dish (Transformation).
