A significant amount of research indicates that multi-tasking does not improve efficiency; and negatively affects results (Junco, 2012).
In order to study smarter, not harder, you will need to eliminate distractions during your study sessions. Social media, web browsing, game playing, texting, etc. will severely affect the intensity of your study sessions if you allow them! Research is clear that multi-tasking (e.g., responding to texts, while studying), increases the amount of time needed to learn material and decreases the quality of the learning (Junco, 2012).
Eliminating the distractions will allow you to fully engage during your study sessions. If you don’t need your computer for homework, then don’t use it. Use apps to help you set limits on the amount of time you can spend at certain sites during the day. Turn your phone off. Reward intensive studying with a social-media break (but make sure you time your break!) See a handout on managing technology for more tips and strategies.
