The SAMR model lays out four tiers of online learning, presented roughly in order of their sophistication and transformative power: substitution, augmentation, modification, and redefinition. When switching to an online format, teachers often focus on the first two levels, which involve replacing traditional materials with digital ones: converting lessons and worksheets into PDFs and posting them online, or recording lectures on video and making them available for asynchronous learning, for example.

Those are important steps, especially when teaching online for the first time, but in classrooms where tech integration has moved to the mastery level, the last two levels of the SAMR model—modification and redefinition—should also be in the mix. Students in classes where this kind of mastery is embedded find more novel and immersive uses for technology. They are creators and publishers of their own work across multiple forms of media, for example, or they are inviting professionals to provide feedback on their work products, or participating in digital forums with other peers around the world.
