To participate or not to participate? A qualitative investigation of students' complex motivations for verbal classroom participation.

Previous research has suggested that making classrooms more active and student centered improves learning, and this usually involves encouraging student talk in the classroom. However, the majority of students remain silent during whole-class discussions, and men's voices are more likely to be heard in science classrooms. Previous interview studies and quantitative studies have discussed the role instructors play in encouraging or discouraging participation, the weight students put into the fear of negative evaluation, and other factors. However, interview studies on the experiences of college students in the sciences, specifically, are lacking. Thus, we conducted a qualitative interview study to investigate students' experiences deciding whether to participate verbally in class, focusing on students recruited from science classrooms. We analyzed the data using an inductive approach and found three main themes: (1) A wide variety of external factors impact students' decision to participate, including instructor characteristics and choices, peer influences, and course material characteristics; (2) Students weigh these factors in complex ways, and this internal calculus varies by student; and (3) Women put greater emphasis on fearing peer judgment, and men may be more motivated by course material considerations. Most of the external factors we identified as important for student participation have been described previously, and we validate that previous literature. We add to the literature by a more complex discussion of how students weigh these different factors and how complex the classroom ecosystem can be. We end by framing our results within the Expectancy Value Theory of motivation, discussing limitations, and providing implications for science college instructors to promote broad and equitable participation.
