College students who are already inclined to multitasking, such as texting and web surfing, are more likely to do it during online courses than in physical classrooms, according to a new study. Researchers recommend online course developers create strategies to increase student focus and discourage multitasking. While this study was done with college students, other similar research on K-12 students often points to the same issues. In a related study in eCampus News, students in Generation Z -- those between ages 14 and 23 -- say they prefer learning via video, while only 26% prefer online classes.
