At each level as SAMR it almost becomes more difficult as you go up the ladder. Not only because it involves a new level of technology, but because it goes from teacher-oriented to student-oriented. It is really easy to substitute a video lesson with a lecture, but it is harder to find a way to redefine a lesson. When choosing what technology to use, a person has to think of all the different ways and the different levels that technology could work on. Some choices of technology are better than others in terms of having room to grow from teacher-oriented to student-oriented. Although it is also dependent on the lesson, I believe that the ability to go to the level of redefinition is largely reliant on the form of technology you choose to use.
