The prime purpose of this paper is to investigate the motivating factors that make university students participate in classroom activities and these factors correlate with their learning and grades. Furthermore, the study tried to identify whether intrinsic motivational factors drove them more to be part of in-class activities or extrinsic motivational factors. The topic under consideration required a qualitative case study with an exploratory design to identify these factors. The study was based at a renowned private sector university in Karachi. The research study used a purposive sampling method and gathered data by conducting semi-structured short interviews of students and faculty with some probing on the answers. The results led to a list of factors such as pedagogy, motivation, role of faculty attitude, role of student attitude, and marks-driven motivation. The findings support the notion that extrinsic motivators play a significant role in class participation of students at the tertiary levels.
