This study investigates how student dissent behaviors are affected by student predispositions (i.e., math anxiety and self-efficacy) in supply chain related courses. The data support a model in which students' vengeful dissent behaviors are indirectly induced by these predispositions through the mediation of perceived immediacy. It is critical for instructors to understand the relationship between these variables to help improve the classroom environment for students, which this study helps to accomplish. Instructors of quantitative courses may need to engage students with predispositions in communication outside of the classroom to foster effective relationship building away from an environment that triggers students' anxiety.
