I think studying online is much more distracting because you have endless distractions at your finger tips. Whereas in your textbook there isn't that much to be distracted by. Also it's easier on your eyes to read off of paper than a computer screen. So maybe that has something to do with it.
I find studying online difficult, having discussions with faceless teachers and classmates I will not meet until graduation. Not being able to access verbal feedback or explanation from instructors require 100% independent learning.
Paper is easier but I've taken a couple of online classes and it was fine. One was the Solar Energy International free introduction to renewable energy course. It was mixed enough with audio, short readings, interactive graphics and exercises, and forums that it was easy to do. I've tried studying how to use Word and Excel online, it seems obvious that that's the right way but I haven't done too well with that. When I study medical or science topics, I prefer a book but I always end up back online watching video clips to help visualize the information. I always thought I prefer books because I'm old but WittyWeddings looks pretty young and she agrees!
Yes! Definitely! Studying on the computer can be very distracting. You go online, chat with friends and go into different web sites and pretty soon you've wasted precious hours of study. Also, staring at the computer screen for long periods can also hurt your eyes.
