"Two well-known reformers in higher education, Clayton Christensen of Harvard Business School and Henry J. Eyring, an administrator at Brigham Young University, signed a letter of support recently for ACTA, the American Council of Trustees and Alumni, that also works for education reform. The main causes of ACTA are 1) the responsibility of university trustees (or regents) and alumni groups to take an active role in the direction of higher education; and 2) turning back the near-universal demand for political correctness on campuses, thereby restoring the tradition of the university as a home for free speech and the exchange of contrasting views. ACTA also promotes cost savings in higher ed, such as the introduction of new technologies for instruction. Christiansen and Eyring are advocates of "disruptive innovation" (their recent book isThe Innovative University: Changing the DNA of Higher Education.), and their views coincide with the those of ACTA on many points."
