Hi Yiran,

You and I have a common point of view that teachers’ education methods for different students should vary from person to person. SAMR is divided into four parts, namely: substitution, augmentation, modification, and redefinition. The SAMR model can help educators think about the role of technology in supporting learning. The SAMR model provides a simpler and easier to measure design. It can test each learning task easily and evaluate the effectiveness of the technology integration in the classroom.
