Teacher expectations and judgments about student capabilities are predictive of student achievement, yet such judgments may be influenced by salient dimensions of student identity and invite biases. Moreover, responsive teaching in mathematics may also invite teacher biases due to the emphasis on student-generated inputs and ideas. Although prior experimental work has demonstrated teacher biases against racially minoritized learners in the context of incorrect or partially correct student mathematical work, less is known about the potential for biases to emerge when teachers are presented with students’ correct and nonstandard mathematical ideas.
In this preregistered experiment, we investigate teacher biases in (a) expectations and judgments about student capabilities in math and (b) teacher responsiveness to students’ mathematical thinking.
Through a between-subjects design via an online survey, we randomly assigned
Our findings show teachers expected greater task difficulty in both the Latinx/e and Black classroom conditions relative to the White. We did not find significant differences by condition in other dimensions, although we found trend-level evidence to suggest that teachers may be more likely to support student sense-making and provide more positive, substantive affirmations to Black students relative to White students for the same mathematical solution. Our findings have implications for research and teacher training in reform-oriented mathematics instruction.
