"All these changes have turned British
universities into elitist sites of consuming knowledge. Students are in many
cases thought to be consumers rather than learning subjects and a lot of
emphasis is given to getting value for their money. The value expectations from
students extend to visual consumption as well, i.e. how students expect their lecturers and tutors to
dress in the class." https://www.tandfonline.com/doi/full/10.1080/03075079.2019.1637839
Still on the
recent paper above published in "Studies in Higher Education" its
worth remembering this study http://ftp.iza.org/dp11000.pdf that concluded: "..women
receive systematically lower teaching evaluations than their male
colleagues”
And also this one: "Instructors
who are viewed as better looking
receive higher instructional ratings, with the impact of a move from
the 10th to the 90th percentile of beauty being substantial" https://www.sciencedirect.com/science/article/pii/S0272775704001165
PS - Anda China even went one step further may be inspired by the motto "give costumers what they want": https://stomp.straitstimes.com/youthphoria/this-university-in-china-only-hires-beautiful-lecturers
