Blackboardâ€™s eâ€“learning system dominates the online learning software market. In this essay I critically examine the structure of Blackboardâ€™s two online learning delivery systems, Blackboard 8.0 and Blackboard CE6. I identify ways in which the platforms both constrain and facilitate instructorâ€“student and studentâ€“student interaction. I addition, I delineate features that sustain and challenge traditional power relationships in the classroom. I conclude with implications for online pedagogy and practical applications for instructors and students.
