Lately I have had several conversations with colleagues and friends about implicit bias and racism. As a scholar of race and schools, and specifically urban education, I am drawn to studying ways that beliefs impact practice. The topic of microaggressions comes up often in my conversations.
Some people are well-versed in what microaggressions are, and can share anecdotes either from their own lived experiences or experiences shared by peers. Others are in a beginning place about the concept and might be skeptical — they can recognize overt forms of racism (hate speech, violent acts) but cannot yet see how a seemingly innocuous compliment is actually a microagression. For instance, I have received compliments about my hair that are veiled inquisitions unto my body: “your hair so so different and pretty! Is it like that naturally, or to you have to do something to it to make it so curly? Can I touch it?” Sometimes the question is left off, and I have had others touch my hair without asking permission. In another instance, I was asked if I “really see myself as a woman of color.” This translates to the classic “you’re so articulate for a person of color” transgression, the sting was much worse because it came from a close and trusted colleague.
An invasion is when someone does not take social cues and assumes the right to ask about another person’s cultural heritage and background or (as in the case of my hair, will go so far as to touch me without permission). An invitation, on the other hand, is the act of inviting a conversation about one’s identity and lived experience. An invasion is like pushing through a door to walk through it, whereas an invitation involves a person coming to the door and opening it for another to enter. As a scholar of urban schools, I’ve been thinking about the types of microaggressions students deal with on a daily basis. I worry about these microaggressions because children do not always have the conversational tools or vocabulary to challenge an adult in a way that sheds light on the microaggression. Children are experts in understanding fairness, and can sense when questions and comments do not feel fair or out of bounds, but often don’t know exactly how to speak up about how something makes them feel.
Below are two examples of exchanges in which a caring adult interacts with a student on the basis of getting to know one another a little bit better. The first is a a conversation I recently heard between a well-intentioned white adult and a ninth grader who is a person of color.
- Adult: What’s something you like about being in this school?
- Student: We don’t have homework at this school! It’s great, I had way too much homework at my old school, I just moved here.
- Adult: So, where are you from? And where’s your family from?
- Student: Harlem. Now we’re in Brooklyn.
- Adult: Oh, that’s quite a distance to travel to get to school in Manhattan. But where is your family from?
- Student: Uhh, yea it’s pretty far I guess. My family is from Mexico.
- Adult: Okay! That’s so great!
(conversation ended here)
Compare the above with the invitation below. In the conversation I heard, a well intentioned white adult had a conversation with a student of color at the same school as above, and with the same goal of getting to know one another a little better.
- Adult: So what’s your favorite food?
- Student: I really love Caribbean food, it’s delicious.
- Adult: Oh, I really enjoy Caribbean food. I really like eating the seafood curries, I wish I knew more about Caribbean cooking. What’s your favorite Caribbean dish?
- Student: I love eating everything. I especially love my mom’s jerk chicken and rice. She is from Jamaica.
- Adult: Oh, okay! Your mom is from Jamaica, do you have family there?
(conversation continues until student passes to lunch in the cafeteria)
An invitation feels natural and builds a bridge between people. When an invitation goes well, sometimes the question about one’s cultural or ethnic heritage might not be needed because the information is raised naturally in dialogue (“She is from Jamaica.”). An invasion is usually met with discomfort or confusion on the part of the student, who is likely to find themselves* in a precarious situation. Power and status hierarchy are at play. A student has to consider the risk imposed if they are seen “talking back” to the teacher/adult in the situation, so the least harmful course of action is to remain neutral and safely exit the conversation with a slightly awkward moment. The most harmful course of action could result in punishment if the student’s response is unacceptable to the adult.
When a student offers information about their identity, slow yourself down and check in with your preconceived notions about that student — we all have them, it is what you do about your preconceptions that will make the difference. Then, pick up on the invitation. Stay on the subject, don’t overgeneralize, and share enthusiasm if you genuinely feel it. Avoid empty praise and gratitude (“That’s so great!”) and do not assume to know more than what is offered. In the second exchange, it would have been a mistake to say, “Where is your dad from?” because that isn’t information the student has offered for the discussion. If as educators, you are able to actively engage and practice authentic conversation with young people, you may find that you experience a shift in your preconceptions about people, and your actions may begin to more wholly support your beliefs about equity and equality.
In the math classroom, invitations and invasions look similar. In one instance, an eighth grade student of color responded to a question posed to the whole group about what they noticed in a table of values. The table contained information about incomes for men and women in the United States. When the student shared that incomes for men are “much more greater by almost double,” the teacher interrupted the student prematurely and then only recorded the word “greater” on the board as his noticing. The student is of West African decent (I know this because I have had conversations with this student) and speaks with an accent. The teacher did not slow down to hear the most important mathematical contribution the student made, he observed one value is nearly double of another. The teacher committed an invasion by interrupting the student, and as I learned later, this invasion was intentional because the teacher felt as though they were not going to understand what was said next. In that moment, I raised my hand to get some clarification on what I heard, and the teacher updated the student noticing to state, “greater, almost double.” This moment was troubling to me for two reasons. First, how will the teacher learn that what they did was silencing to the student, and did my actions do anything to help the student speak for themselves? I used my power and privilege in the classroom as a math coach and I knew I would be called on immediately and that my contribution would be heard and recorded. In this case, I followed up with student and teacher about the moment afterwards, but how many of these interactions go unchallenged?
In my separate debriefs with the teacher and student we talked about strategies that could be used to slow down in the teacher’s case and speak up in the student’s case. The teacher admitted to being a little confused by the student’s accent, and we talked about how to slow down to help avoid an invasion, and ask for students to repeat themselves loudly so that they are heard. It is okay to say, “I didn’t hear you, can you please repeat that?” Research shows, unsurprisingly, that by listening to an accent that is different from yours for longer periods of time, your brain maps the words you hear onto the words you already know and comprehension improves. And just think about the types of invitations that may occur as you hear your students speak freely with you! The lesson is, listen to your students more. For my debrief with the student, I asked them how they felt when they were misunderstood, and the student shared feelings of confusion and sadness. We talked about how it is okay to say, “that’s not exactly what I said.” It is not a perfect strategy because it does not level the power structure between teacher and student, but it does at the very least give more voice to the student for a brief moment.
We cannot go through with our daily work feeling proud of our equity-based stance on mathematics education, it is not enough and we must actively work on changing our preconceived ideas about groups of people who are different than us. Well-intentioned educators of various racial, ethnic, gender, and other social identities commit microaggressions and invasions all the time. In my experience, and largely in the literature on microaggessions, invasions are more frequently committed by people from the dominant culture – straight, cisgender, financially stable, white people, however, nobody is off the hook. What I propose in this blog is that there is a great need for math educators to actively practice engaging in and picking up on invitations into dialogue with students, because students in most instances do not have the power or privilege to challenge invasions levied upon them. To avoid committing invasions my advice is simple — slow down, check in with preconceptions, and listen with care.

analyze this graph; notice the y-axis (vertical axis) is inverted and the values decrease from bottom to top. Did you think gun deaths went down prior to “Stand Your Ground” law? At first, so did we. After having a chance to unpack features of the graph, one student asked, “Wait – wasn’t Trayvon Martin killed in Florida? What year was he murdered?” Trayvon Martin was killed in 2012, and it was powerful to hear a sixth grader ask this question because this student was making an important connection. A great math lesson about interpreting graphs will help students make sense of data, but an empowering lesson about graphs will motivate a student to research, question, analyze, and critique the way things work in the world.
