What SAMR and Sections share is that they are both criteria to measure whether the usage of multimedia is appropriate and effective. SAMR represents substitution, augmentation, modification and redefinition. SECTIONS model refers to eight standards: students, ease of use, cost and time, media characteristics, interaction, organization, networking, security and privacy.

There are mainly three differences between the two measuring models. Firstly, SAMR mainly focuses on the media forms themselves. The four aspects are aimed to determine whether the selected media can bring transformational function or just serve as a substitute of the original traditional tool. However, Sections model not only pays attention to the media, such as media characteristics and interaction, but also takes the receiving objects—students into consideration.

Secondly, SAMR and SECTIONS can be used in different situations. SAMR is more useful when teachers are selecting among different multimedia forms in a particular place, such as in a classroom, for students with almost similar background and resources. SAMR can allow teachers to mainly consider the relationship between the media and the knowledge without being bothered by many other factors. By contrast, SECTIONS should be employed when situations are more uncertain and more complex. For example, when the teachers are going to spread knowledge in a larger area and for students from various background, they must think carefully about whether the students have qualified skills and resources to access the tools, whether the high-performance tools can enhance the interaction among students and teachers, and whether the tools are truly secure enough to protect every student’s privacy and dignity.
