With more freedom in scheduling, students are able to work more days and acquire enough money to pay off their student loans with much more ease than attending a crowded traditional school . In the Ottawa Business Journal, author Kate Chappell's article, "Post-Secondary Institutions Go Electronic," notes that with the creation of personalized smartphones, tablets and cloud computing, an endless array of educational materials are now available to students , allowing them to “be able to download course material to their portable device” (Chappell) This allows students to access their notes and course material as long as they have an internet connection, giving them the ability to keep intact their materials on a digital database, avoiding dependence on computer storage to securely protect their files for the remainder of their use allowed teachers and students to observe their own educational growth and provided a means to view the same lesson as many times as they wish (Afshar). , students using smartphones are provided convenient access to any distance learning course, or materials relevant to it, by simply downloading an application from the "app store" or visiting a mobile web page to access home/work in class and other important elements for success in the classroom. While technology, in general, is very prone to failure, public places like local libraries offer free Wi-Fi connections and computer use, giving students myriad opportunities to complete their digital courses. Distance learning can also be used to identify and track a student's errors and progress, allowing them to identify how well they are doing and what they need to improve on to improve their performance.
