People's personal, professional, social and cultural lives have been affected and transformed by the computer networking revolution: email, cellphones, text messaging, Twitter, participating in social networks, blogging and accessing powerful search engines using computers and/or mobile devices are common aspects of everyday life. Educators are challenged to respond to the internet. There is a need to reflect on people's theory of learning, and to rethink and reassess teaching practices and pedagogical approaches in relation to the opportunities afforded by online technologies. A theory is an explanation for why something occurs or how it occurs. Typically, theory is generated by a question or by curiosity, and offers a response to that question. The term "epistemology", offers a powerful tool for understanding learning theory, and it is a tool that educators should embrace and use in discussing learning theory and how people view teaching and learning.
