Does class size matter? http://www.magnapubs.com/newsletter/distance-education-report/270/Does-Class-Size-Matter-13523-1.html This article originally appeared in Distance Education Report. I've been the director of online education at my institution since 2007. One question I've been asked many times over the years is "What is the optimal number of students to have in an online class?"
