Student engagement is considered to be among the better predictors of learning, yet there is growing concern that there is no consensus on the conceptual foundation. The authors propose a conceptualization of student engagement grounded in A. W. Astin's (1984) Student Involvement Theory and W. A. Kahn's (1990) employee engagement research where student engagement is built on four components: emotional engagement, physical engagement, cognitive engagement in class, and cognitive engagement out of class. Using this framework the authors develop and psychometrically test a student engagement survey that can be used by researchers to advance engagement theory and by business schools to monitor continuous improvement.
