Access to more information and student autonomy are the principal advantages of increasing the use of electronic devices in education. With the internet, students can access all the information available about any topic, regardless of what books and other resources are available in the school. Furthermore, students can focus on whatever topic or subject they want and study it in depth. A prime example of this is the number of online university courses available to students, covering a myriad of subjects that, up until recently, were unavailable to most learners. This has resulted in more people studying third-level degrees than ever before at a pace and schedule that suits them.
