In order to improve the quality of instruction at the college and university level, all faculty should be required to spend time working outside the academic world in professions relevant to the courses they teach.
Whether college faculty should also work outside academia, in professional work related to their academic fields, depends primarily on the specific academic area. With respect to fields in which outside work is appropriate, I strongly agree with the statement; students and faculty all stand to gain in a variety of respects when a professor complements academic duties with real-world experience.
As a threshold matter, the statement requires qualification in two respects. First, in certain academic areas there is no profession to speak of outside academia. This is especially true in the humanities; after all, what work outside academia is there for professors of literature or philosophy?
Secondly, the statement fails to consider that in certain other academic areas a professor's academic duties typically involve practical work of the sort that occurs outside academia. This is especially true in the fine and performing arts, where faculty actively engage in the craft by demonstrating techniques and styles for their students.
Aside from these two qualifications,I strongly agree that it is worthwhile for college faculty to work outside academia in professional positions related to their field. There are three dear benefits of doing so. First, in my experience as a student, faculty who are actively engaged in their fields come to class with fresh insights and a contagious excitement about the subject at hand. Moreover, they bring to their students practical, real-world examples of the principles and theories discussed in textbooks, thereby sparking interest, and even motivating some students to pursue the field as a career.
