Self study and traditional classroom learning complement one another. When used together, they help students learn and retain information better however, the world is becoming more accustomed to the benefits of solely self learning.The Internet is an optimal resource for aspiring autodidacts, and with more sites being geared specifically towards learning anytime and anywhere, individuals all over the world have access to a cost efficient and customizable education. Udacity, edX, Coursera, and Academic Earth are just a few of the low cost or free education providers available through the web. Classes covering physics, law, business, engineering, politics, history and more are available and many contain lectures, quizzes, and tests that students complete at their own pace. Because of this autodidactic approach, students in MOOCs have been found to test better than students taking the same courses in large in person lectures.While it is unlikely that the classroom as an educational forum will ever be entirely replaced, as the benefits of a physical space for collaboration with intellectual and social growth is undeniable, self learning will likely become increasingly integrated into traditional educational institutions. Students of all ages may find exploring a subject matter of interest or learning a new skill on their own time, and at a low cost, to be highly rewarding. After all, a sense of freedom and self determination can come with being your own teacher, as it is believed that if people begin with learning what they really want to, then that thirst for knowledge will spread to other subjects.
