Teacher diversity is a contemporary issue in education circles that is prevalent in the current educational discussions. Few would discount the power and promise of diversifying the teaching force, especially in STEM fields; however, our research offers the field of STEM education new insight into the conversation. We counter that any discussions of teacher diversity in STEM education must include issues of how race and racism impact Black teachers’ experiences in the classroom as well as issues related to their recruitment and retention (Frank et al.). While our work centers on Black teachers, we have learned from fellow researchers and educators that much of what we will share in this blog resonates with other teachers of color as well (see Kohli, 2016).
Many of the tacit and overt ways that racism plays out in the careers and policies that affect practicing STEM teachers are mirrored in STEM preservice teacher education. Many of these issues are rooted in how STEM subjects are perceived. Those who work in STEM disciplines are often afforded unwarranted prestige (Vilson, 2017) simply because STEM disciplines are seen as attainable by an elite few. Just as students who achieve in STEM fields are lauded for their “brilliance,” STEM teachers are often revered for teaching a subject area that many find to be unapproachable. We have argued (Terada, 2021) that the maintenance of false perceptions about STEM disciplines, specifically mathematics, plays a role in Black teachers’ participation in the field, and as a corollary, Black preservice teachers.
The data we share here are from our four-year study funded by the National Science Foundation (DGE 1669733) entitled: Examining the Trajectories of Black Mathematics Teachers. We looked deeply at the role that race, and more specifically racism, plays in the teaching, retention, and recruitment experiences of Black mathematics teachers. We examined the issues both as contemporary concerns but also from a historical perspective, given the role of the Brown v. Board of Education decision in the pushout of Black teachers in integrated schools. We collected data from several sources: interviews with retired Black mathematics teachers who taught pre- and post-Brown (Figure 1), focus groups with currently practicing teachers, and a survey of over 1,000 Black teachers who are presently teaching mathematics. In this blog, we shift our lens to preservice STEM teachers and share our perspectives on what preservice STEM teachers and teacher educators can learn from our findings.

The Diversity Imperative
The desire to diversify the STEM teaching force is rife with “good” intentions. Arguments for teacher diversity, particularly when focused on Black teachers, are often grounded in several common arguments: (a) the teaching force is primarily white and female; (b) demographics of school faculty should match those of the schools where they teach; and (c) Black teachers are social and academic role models for Black students.
Similar to teacher diversity, STEM teacher recruitment is a longstanding issue in education. Secondary STEM fields consistently rank at the top of lists of critical teaching shortage areas. A leading argument for bringing more STEM teachers into the field is rooted in commodification. For instance, the desire for the U.S. to maintain global competitiveness foregrounds many conversations regarding STEM teacher recruitment with little thought as to how people shape the field. As Dr. Rochelle Gutiérrez reminds us in her presentation, “Rehumanizing Mathematics: A Vision for the Future” (Figure 2), mathematics needs diverse people as much as diverse people need mathematics.
Figure 2. Dr. Rochelle Gutiérrez speaks at the Latinx in Mathematical Sciences Conference (2018).
Taken together the need for diverse teachers and the need for more STEM teachers taken collectively as an argument for STEM teacher diversity are still insufficient in their rationale for recruiting Black teachers and other teachers of color. Teacher education and educational leaders need more nuanced explanations for why diversifying STEM teaching is important to avoid slippery slopes of commodification of teachers’ labor.
The Tacit and Overt Ways that Racism Operates in STEM Teacher Education
When examining preservice STEM teacher education, we find that tacit and overt racist practices often underlie standard policies and practices. For example, teacher accrediting bodies require teacher education programs to set arbitrary metrics for the diversity of their programs while simultaneously upholding teacher testing policies and curricular mandates that have long histories of excluding Black preservice teachers from becoming teachers.
Tacit and overt practices in teacher education also show up in curricular decisions, or in many cases, curricular erasure. In focus groups across the country, Black mathematics teachers shared how they were not prepared to teach mathematics in culturally specific ways. In fact, one teacher noted how she had to do her own digging and research to know more about the contributions of Africans and African Americans in mathematics because this information was not part of her mathematics teacher preparation. In our findings, we also learned that many Black teachers felt their mathematics preservice education was better suited for non-Black teachers. For example, one teacher in our focus group data noted that when learning about working with families, the lessons in preservice education are often designed for an imagined white teacher who will work with families of color, particularly in programs geared toward working in urban schools. She queried what these lessons might look like for Black and other preservice teachers of color with shared cultural identities.
Sorting and filtering processes like testing, the isolation in STEM programs, and little to no acknowledgement of alternative ways of knowing and doing mathematics among Black preservice teachers are just a few of the barriers noted among teachers in our study. As teacher educators, we must do the difficult work of reflecting upon how our practices and policies perpetuate the very inequities we intend to dismantle. We must do this reflection across all aspects of our work, including how we conceptualize STEM and its purposes, how we present content, and how we acknowledge the cultural nuances of pedagogical practice.
Ways to Amplify the Voices and Needs of Black Preservice Teachers and Other Preservice Teachers of Color
Survey, interview, and focus group data from the Trajectories project illuminated the many ways race and racism permeate the experiences of Black mathematics teachers. Based on what we have learned, we offer the following suggestions as ways to translate research findings into actionable shifts for Black and other preservice teachers of color.
It is our position that STEM teacher retention often begins with STEM teacher preparation. If STEM teacher educators can examine the STEM teacher diversity dilemma through a lens of race and its role in access and belonging for preservice teachers, we believe we can get to the root of many issues related to low enrollment among Black students in STEM education programs. Further, we assert that looking at STEM preservice teaching issues through the lens of race sheds new light on longstanding teacher education policy and practice issues. Closing We are excited that our project has generated conversation about teacher diversity in mathematics and other STEM disciplines. We also encourage other researchers to extend this research in ways that explore how race and racism impact teaching force participation. Such avenues include examining the lived experiences of non-Black teachers of color, continuing to collect oral histories of retired mathematics teachers, and investigating issues of racism in other STEM disciplines. Ultimately, developing a workforce that mirrors the richness and diversity of our student population calls for new questions and new modes of inquiry.
