Traditional college instruction is part of a well-established tradition that has remained fairly unchanged over time. Becoming an instructor in this environment has meant conformity to teaching standards that have also remained fairly unchanged. A college professor is associated with someone who is a subject matter expert, likely to achieve a position with tenure, and have dual roles as an instructor and researcher. It is expected that they will be published authors of scholarly journal articles that have been peer-reviewed and contributed knowledge to their field. While this form of education and instructor still exists, there is another academic institution that has also been established and it is an online college and university.
