More than eight in 10 professors say universities’ excessive use of digital technologies is harming academic freedom, according to a survey of academics in the United Kingdom. The poll of more than 2,000 scholars conducted for the University and College Union (UCU), which represents 120,000 faculty and staff members in the U.K., highlights growing unease over the digital tools commonly used in academe, such as the virtual learning environments used to facilitate teaching, electronic systems to evaluate teaching performance and metrics-based systems such as SciVal that enable managers to scrutinize research publications and citations.
