The document discusses Bloom's Revised Digital Taxonomy and the SAMR model. Bloom's Taxonomy was revised in 2008 to incorporate digital tools and help teachers select activities based on students' mastery levels. The SAMR model, created in 2006, has four levels of technology integration from substitution to redefinition. Both frameworks aim to transform traditional teaching with technology and their levels can be correlated. When used together, they create rigorous 21st century learning experiences for students.
