Engagement is a prominent theoretical orientation that has received great attention from educators and researchers. This article provides a literature overview of the engagement construct pertaining to its various definitions, dimensions, and major conceptualisations. In addition, the review sheds light on two major approaches to engagement in the current literature: one entails students' cognitive, behavioural, and emotional engagement (Fredricks, Blumenfeld, & Paris, 2004), and the other approach is characterised by vigor, dedication, and absorption (Schaufeli, Salanova, Gonzalez-Rom, & Bakker, 2002). Further, the association between these two models and students' performance is discussed.
