One of the biggest issues in eLearning is distractions. The brain is constantly bombarded with stray thoughts even when users exert great self-control. The problem is yet more pronounced in mLearning, as devices themselves may cause distractions such as phone calls, email alerts, and the knowledge that the user could easily be doing something different. The average mobile user also has a short attention span — most people skim headlines and prefer bite-size content to long articles.
The reason learners forget so much of the information they learn within a course is partially due to distractions and partially to the fact that there is often too much content included in a single training lesson. In order to be successful, developers must create mobile learning courses that gains and sustains the attention of a user and can compete against distractions.
