The idea that you can just put stuff out there, and that it will magically be effective and used effectively — there’s just no evidence of that,” Twigg says. Collecting evidence requires integrating with college classrooms, which requires scale and support, which requires money, she says. Lots of it. “Sixteen million dollars is not chump change,” says Twigg, “but you need to be able to support and sustain it.” Nonprofit projects in higher education do not have a great track record on this, she points out, not even the most highly regarded ones.
