Answer:
Smartphone Use and Lower Grades
Step-by-step explanation:
This grade could be the difference between passing and failing for some students. Even students who were enrolled in the same class as the device-users scored lower even though they did use a device during class. The researchers speculate that this was likely due to the surrounding distractions from others using electronic devices.
It's also important to note that while having a device did not lower comprehension scores within the lecture, it did lower the end of the term exam by as much as 5% or half a grade. These findings demonstrate that the main effect of divided attention in the classroom is on long-term retention.
Meanwhile, another study conducted by Stanford University shows that intense multitasking decreases the efficiency of completing a given task. The conclusion here is that smartphones and other electronic devices can reduce a student's ability to think to their full potential.
