Answer:
Since 2012, we have tracked the frequency with which students use various technologies for their coursework and the levels of importance students attribute to these technologies for their academic success. We should not be surprised that student use of and the importance placed on those technologies for students' success are significantly and positively correlated: The more courses in which students use the various devices, the more important they consider those devices to be in accomplishing academic tasks successfully (see figure 2). Laptops continue to reign supreme, with 98% of students reporting using them in at least one course last year and 94% rating them very or extremely important.1 Similarly, smartphone usage and importance both increased modestly since 2017, continuing an upward trend for the third year in a row. More surprising is the reversal of fortunes for desktops and tablets. After two consecutive years of decline in importance and use, these devices have experienced a substantial rebound, especially in terms of the percentage of students who have used them for at least one course.2 Comparatively fewer students reported high levels of use or importance with many of the newer and/or narrower technologies such as AR and VR headsets, smartwatches, gaming devices, streaming media devices, and voice-controlled speakers/assistants.
Digital technology enables the storage of massive amounts of information in relatively small spaces. Large amounts of media, such as photos, music, videos, contact information, and other documents can be carried around on small devices like mobile phones.
