The oldest team in the NBA?

The oldest team in the NBA?

I attended Joel Bezaire‘s Sports Analytics session at TMC18. It was awesome! Joel has done an amazing job developing a curriculum based on Sports Analytics. I decided to share a lesson I did this past year involving sports. It’s nowhere near as good as Joel’s lessons, but I think it could be something with a little work.

One storyline during the 2017-18 NBA season involved the advanced age of the Cleveland Cavaliers roster. In October, ESPN’s Brian Windhorst published the article “Cavs the oldest in a long line of old LeBron teams.” The article contained the table shown below:

ESPN Table

I presented this table and the article’s headline to my Integrated Math 1 students and asked them to Notice and Wonder. This was quite a few months ago, so I don’t really remember how the discussion went. We ended up talking about whether it made sense to use the average to determine the NBA’s oldest team. I proposed a roster consisting of three of my 14-year-old students, my pregnant colleague’s soon-to-be-born child, and one of my colleagues who I joked was 185. They quickly saw that this team’s average age would reveal very little about how old or young the team really was. We decided that we needed a better way to discuss a team’s age.

From this point, the lesson didn’t go how I had hoped. I gave every student or pair of students a team roster and told them that I wanted the class as a whole to find a way to compare team ages across the league. I provided the entire class with a single piece of poster paper that they could use to present the information using whatever representation they liked. Although I didn’t say it, my intention was for students to make a box plot for each team. If nothing else, I expected students to go beyond simply reporting an average age. The results were decidedly mixed. I think this task focused too heavily on calculation and representation, and it did not focus enough on thinking and discussion. Interestingly, several students told me then and later in the year that they really enjoyed getting to work with the NBA rosters. There’s definitely the potential for a good activity here; I just haven’t found it yet. Let me know if you have any ideas!

July 27, 2017: The Terror of Twitter Math Camp

July 18-19, 2018: #descon18 and day one of #TMC18

Something has changed. It’s all still here – the anxiety, the relentless train of thoughts, the confusion about what to say and where to sit, the feeling that I don’t really belong. It’s all still here. But it’s better. It’s better. I know people.

When I arrived Wednesday morning, I sat at a table in the atrium to collect myself. Lisa Henry came over to welcome me. I talked with Dave Sabol, who I knew from my time student teaching at Saint Ignatius, for a few minutes, and as I sat waiting in Rade Dining Hall, Cindy Reagan, another Ignatius teacher I know, sat down and talked with me. At one point, Chris Luzniak, my TMC mentor last year, came over, gave me a hug, and asked about how my year went. I exchanged smiles with a number of people who remembered me from last year, even if they didn’t know my name or hadn’t really talked to me before. This morning, Joel Bezaire greeted me by name at his morning session. Mark Kaiser, another Ignatius teacher, sat next to me for My Favorites and the Keynote, and we chatted. When I arrived at an afternoon session, Lisa Bejarano and Kent Haines greeted me. Lisa gave me a hug and mentioned that she saw me tweeting so knew I was around somewhere. It’s an unfamiliar feeling: Someone knows I’m here.

I was never an especially social kid. I’m not sure I really knew how to be social, how to have friends, how to exist in “that” world. Two memories stand out. I recall getting together with a friend shortly after high school. “Okay, Dan, I guess I’ll see you in six months.” That’s what he said to me when we parted. It wasn’t meant in a sarcastic or cruel manner. I suppose in a sense it was almost wistful. He knew a simple truth: Even if he asked me to do something every day, it would likely be a long time before I agreed to do anything again. Whether it was shyness or laziness or anxiety or apathy or something else entirely, I simply did not spend much time being social.

The other memory involves the transition from fifth grade at an elementary school to sixth grade at the middle school. Because the middle school brought students together from four different elementary schools, the school tried to make sure that every student shared homerooms and teams with at least a few other people from elementary school. I did not. Well, that’s not exactly true. I knew Troy and Mike. They had never been what I’d call friends. They were just two boys that I knew. We got along fine; we just never had much occasion to spend time together in elementary school. But they were really the only two people I knew in sixth grade. The three of us made an odd bunch, but at least we had a group. I guess you could say we took care of each other socially. None of us were especially outgoing, and we were close to as far from popular as one could get. But we had our friendship, and I think it meant something for all of us. Although it’s been twenty years, I still remember the day I dropped my pencil box on the stairs and Troy came over and blocked the stairwell so that I could pick up my supplies. Maybe it’s not the most exciting or heartwarming childhood memory, but it has stuck with me for this long. I imagine it always will.

Marian Dingle spoke today about her children’s experiences in school. She told us how her son and daughter both had teachers with whom they formed no real connection, teachers that didn’t know them, teachers that made school a less welcoming place. For Marian’s daughter, sports, which sometimes serve to bring people closer, only seemed to exacerbate the feeling of not belonging. Despite Marian’s best efforts as team mom, her daughter did not develop the sense of kinship with her school volleyball team that is the hallmark of great youth sports programs. Fortunately, Marian’s daughter found this connection with her club volleyball team, and fortunately, Marian’s daughter had parents who strove to help her center herself in family, in community, and in her culture.

But what about the kids who don’t have this? What about the kids who walk into class and don’t know where to sit? What about the kids who hate group work because they know that no one will want to work with them? What about the kids who hope every day that they’ll be able to find an open seat in the cafeteria? What about the kids who believe that no one notices them? What about the kids who think their voices are never heard? What about the kids who feel like they just don’t belong? And maybe they don’t belong because we don’t let them belong or help them belong or provide a space for them to belong in. And maybe we don’t notice them and we don’t hear them because we don’t try to hear them or we don’t want to hear them. And maybe we just tell them to sit anywhere or to make a new friend or to just ask someone else in class because that’s what we would do and it seems so simple unless you’re 13 and you feel like you don’t belong. And maybe we send the message every single day that they really don’t belong. Intentionally or not, maybe everything we say and do sends that message. And maybe they see that message and hear that message every day at school. And we don’t do anything about it.

I teach at the middle school I attended. I’ve lived in the same community for my entire life. I don’t have any answers or at least not enough answers. All I have is the will to keep trying. To keep asking questions. To keep fighting. Because they do belong. And they deserve better.

Thank you Lisa and Dave and Cindy and Chris and Joel and Mark and Lisa and Kent and everyone else. You’ve made a difference for me. And thank you, Marian, for sharing your story and for fighting for kids.

The Marzano Tweet

What follows are my thoughts on the response to the Marzano tweet shown below. I offer these thoughts as my way of grappling with an important issue in education – the interplay between educators and non-educators. My intention is not to criticize or disparage any individual but to work toward a way for me to understand discourse about education. I hope that I at least partly achieve this goal.

Robert Marzano is an educational researcher, consultant, and chief academic officer at Marzano Research. I know him primarily from his book The Art and Science of Teaching.

I did not have the same visceral reaction to the Marzano tweet that so many others did. That’s not to say I liked it. It just didn’t upset me. I have too much on my mind to worry about what Robert Marzano thinks. But I understand why so many teachers felt compelled to criticize him. When someone shares a message about education that we know is false, misleading, or harmful, it’s important for us to dispute that message. It’s important for us to share our own knowledge and perspectives. We can’t let a false narrative dominate. So I understand the response to the Marzano tweet.

But I also don’t understand the response to the Marzano tweet. I saw quite a few comments about Marzano’s background. People criticized him for only having spent two years in the classroom and for not having been in the classroom for 30+ years. The message here seems to be “Who are you to say anything about teaching when you don’t even teach?” I find this troubling.

Are teachers the only ones with valuable insights into teaching? Is anyone else qualified to share their opinions about education? Should we reject all educational research unless it was conducted by a classroom teacher? How long can you be out of the classroom and still have a worthwhile perspective? Coaches and administrators aren’t classroom teachers – do their contributions have any value? What about counselors and school psychologists? Who do we consider close enough to the classroom to judge their ideas worth considering?

Politicians, to take one example, rarely have teaching experience. Yet politicians write every education law, and all too often, teachers have little to no input in the legislative process. It can be distressing to think that education policy has largely been crafted by people with little to no experience as educators. They rely, of course, on input from many groups – researchers, lobbyists, etc. – but ultimately, the politicians pass the laws.

Is it fair to criticize politicians for education law? I think so, but the target of the criticism matters. It’s fair to say that a law is bad policy. It’s fair to say a law is based on shoddy research. It’s fair to say a politician didn’t consult with enough people or with the right people. It’s fair to disagree with a politician’s beliefs, and it seems fair to question a politician’s knowledge and understanding of issues in education. But is it fair to criticize a politician for never having been a teacher?

Ideas should be judged based on their merit. Anyone can have a great idea. An idea isn’t great because it came from a teacher; it’s great because it’s useful somehow. Similarly, a bad idea isn’t bad because it came from a non-teacher. An idea is bad because it offers nothing useful or it’s harmful or it ignores the research or it’s based on misconceptions or for any of a number of other reasons. The idea itself must be flawed. An idea isn’t bad simply because of who offered it.

Perhaps it’s more likely for bad educational ideas to come from non-teachers and for good ones to come from teachers. But we all know that not every idea a teacher has is a good one, and I hope we’ve all heard good ideas from non-teachers.

I don’t agree with the message Marzano shared in his tweet. I don’t agree with it because it’s wrong for so many reasons that people have already shared. It’s wrong if Marzano hasn’t taught in 30 years, and it’s wrong if he went back in the classroom today. What matters is the quality of the idea itself. I worry about what happens to discourse when we reject an idea because the person who suggested it lacks a certain title, background, or experience. But I also wonder how to reconcile this worry with the reality that everyone considers themselves qualified to offer opinions on educational issues. Is there a clear line somewhere? It’s certainly not “teacher vs. non-teacher.” After all, some of the best ideas in math education right now come from Desmos and Illustrative Mathematics, and as far as I can tell, most of their employees are not currently in the classroom. I don’t have an answer. I’m not sure there is an answer. I just needed to write this all down.

What Do My Students Really Know? Part 2

During the second semester, I only assigned homework using Delta Math. This worked well for several reasons, with the most important one being that it gave me better insight into what my students actually understood than pencil-and-paper homework ever did.

The Delta Math homework I assigned surprised me right off the bat. The image below displays one student’s results on the first assignment of the second semester. Many students had similar results.

HW 1 Linear 1

This assignment consisted entirely of review material. We had assessed linear functions at least once in December, and for the most part, students did fine. I knew that students would be a bit rusty after Winter Break. That’s why we completed this assignment. The surprise came from the misconceptions I saw in student responses.

This slideshow requires JavaScript.

Although I could only see their answers, I found it relatively easy to determine their misconceptions. Unsurprisingly, I saw all of the classic slope mistakes.

  • Writing slope as an ordered pair instead of a ratio
  • Subtraction errors, especially with negative numbers
  • Putting the change in x in the numerator instead of the denominator
  • Mismatching x and y
  • Forgetting to simplify (not exactly a mistake, but Delta Math marks this wrong)
  • Misinterpreting \frac{4}{0} as either 4 or as 0

These aren’t new mistakes. I’ve seen them many times, and we’ve corrected them together many times. We said “vertical divided by horizontal” at least ten times each class period every day for a month. And the students got this! Like I said, students did fine when we assessed linear functions in December.

So why did so many students continue to display these misconceptions? I’m not naive. I realize that students master the material at different rates. But how could so many of them who had mastered the material make these mistakes? Why did they return to misconceptions that they had overcome a month earlier?

One explanation is that students managed to know the material well enough to pass an assessment, but they did not develop the robust understanding necessary to maintain their skills even a month later. That’s the explanation I originally subscribed to, but I think it lacks something important. Many of my students did understand slope. Throughout the fall, they worked hard to connect proportional relationships, steepness, and lines. They built a solid conceptual foundation. They thought mathematically. They solved problems. I think what they lacked – and this is on me – was a proper emphasis on procedural fluency. Sure, we had plenty of opportunities to practice and to develop that fluency, but rarely did they have the “Uh oh, I’m wrong!” moments that Delta Math gave them. My Delta Math assignments required students to get a certain number of problems correct to get credit. You just can’t fake a right answer. That’s what I like about Delta Math – it holds them accountable.

The other major advantage of Delta Math over pencil-and-paper homework? I can look through as many assignments as I want to in a relatively short time period without having to carry papers around. I have a bit of a problem with keeping papers organized, so moving homework online and avoiding paper altogether saves me some serious time and energy. The obvious drawback is that I cannot see the work that the students did. In the examples above, it’s relatively straightforward to identify misconceptions without seeing the student’s work, but that certainly won’t always be the case. I think, though, that simply being able to see that a student struggled with a problem type may be enough, especially given that some sort of intervention would need to take place anyway.

I’m not sure yet what homework will look like in my classes this year, but it seems like I’ll want to place more emphasis on procedural fluency. Perhaps such an emphasis earlier in the year will lead to better understanding all year long. I hope 2018-19 is the year I finally figure out how to make homework work for me and for my students!

Sandra Cisneros – “One Holy Night”

Sandra Cisneros – “One Holy Night”

Last summer, I read two books with a student. We read The Awakening by Kate Chopin and Mrs. Dalloway by Virginia Woolf. Our conversations about The Awakening proved fascinating, but we didn’t have as much success reading and discussing Mrs. Dalloway. Nevertheless, I found the experience meaningful, and I think the student did too. She sent me the following Remind message before the school year ended:

Hey Carlson, are we reading this summer?

How could I say no? We haven’t yet started, but we plan to read The Piano Lesson by August Wilson. Additionally, I asked one of my students from this past year if she would like to read a book with me, and she agreed. We’ve been reading Woman Hollering Creek and Other Stories by Sandra Cisneros. The story “One Holy Night” led to an interesting discussion. Here are the highlights and my rambling commentary. To maintain her privacy, I will refer to my student simply as C.

In “One Holy Night,” an eighth-grade girl tells of how she loses her virginity to a man who calls himself Chaq Uxmal Paloquín. He claims to be descended from Mayan kings. The people in the neighborhood call him Boy Baby, and no one seems to know much about him. We find out later – after he has left town and our narrator has become pregnant – that he is actually thirty-seven years old and that he is a serial killer. The story is only nine pages long, and it focuses more on mood and feeling than on specific details.

For whatever reason, our conversation fixated on rape. C rightly pointed out that Boy Baby committed statutory rape. She expressed some discomfort with the story and mentioned that some readers might be deeply disturbed (“triggered”) by the story. We talked about the choice Cisneros made to avoid detail and use poetic language to describe the rape:

Then something inside bit me, and I gave out a cry as if the other, the one I wouldn’t be anymore, leapt out.

C was glad that there wasn’t more detail. Because rape is so disturbing, she asserted, only a bad writer would need to include more detail to bring about the desired response from the reader. This assertion seemed to extend past “One Holy Night” to all literature (and other works of art, for the matter), so I asked if there could ever be a situation in which more detail might be necessary. She said no, again emphasizing that a good writer wouldn’t need to include the details of the rape. I told C that I didn’t disagree but that I wanted to press the point further. Could there be any value in graphic description of such a violent act? And what about other violent acts like murder? C felt that rape belonged to a category of its own, that it was even worse than murder. I wondered whether a rape victim might consider it necessary to express the horror and the violence she went through. C agreed this might be possible, but she expressed her concerns about works of art that use such violence for shock or entertainment value. She talked about the show 13 Reasons Why (which I have not seen) and how she felt like it glamorized suicide. We talked about how the narrator seemed to romanticize her own rape, describing Boy Baby’s face as “the face I am in love with” even after discovering he’s a serial killer. It was a meandering conversation, but it was a meaningful one.

When I chose Woman Hollering Creek and Other Stories, I didn’t know much about its content. I didn’t intend to pick a book with a story about a young girl’s rape, so I’m glad that C and I managed to have such an interesting discussion. I’m forced to wonder where this sort of conversation takes place. Or if it even does. It’s not easy to talk about rape, but it seems important that we do. Sometimes we don’t give our students enough credit for the depth of their insights. I look forward to learning more with C as the summer continues.

Black History Month

I took a risk this February. My school celebrates Black History Month in a number of ways, but I always feel like I need to do more. Here’s what I tried.

I’m not sure what made me think of this, but I decided that we would read a poem by an African-American poet each morning in homeroom. I figured this could be a simple yet powerful way to celebrate African-American culture, and honestly, I just thought it would be interesting. You can find the poems I used here.

I wasn’t really sure what to expect the first day. Would the students really listen? Would anyone want to participate? Would the experience be meaningful to anyone but me?

I explained to my homeroom the plan for the month. I told them that anyone could volunteer to read a poem or even bring in a poem of their choice. As I prepared to read the first poem, I paused and thought “Why not ask for a volunteer now?” I expected dead silence and blank stares. Instead, an energetic, excitable young man – who happens to be African-American – said he wanted to read the poem. Overjoyed. I was absolutely overjoyed.

As the month continued, I kept bringing in poems, and my students kept volunteering to read. It might have only been 7 or 8 students, but when I started, I had no expectations whatsoever. And while my students sometimes struggled to read the poems, they truly committed themselves to their delivery. And the rest of the class? Quiet, respectful, attentive. Did they find the poems interesting or meaningful or enjoyable? I can’t say, but I do know that they respected my idea and made it a reality.

Students read nearly all of the poems. I had to read 1 or 2 because of time constraints, and I asked a guidance counselor to read one. Her reading of Audre Lorde’s “Hanging Fire” truly moved me. I had hoped that having a “guest reader” would be special, but I was totally blown away. I think the kids were too.

For the last day of February, I decided to talk briefly about the idea of Black History Month and close with a short selection from a poem that means something to me. I thanked my students for committing to the poem readings all month and told them that I would really miss not having a poem to read every day. Then, I attempted to tell them how I’d like us all to carry the message of Black History Month forward. That we need to spend all year trying to make our school, our community, and our country more tolerant and more just. I think I stumbled over my words a bit here. I was emotional, especially knowing what would come next. I closed with the last few lines of Amiri Baraka’s “Three Modes of History and Culture.”

I think about a time when I will be relaxed.
When flames and non-specific passion wear themselves
away. And my eyes and hands and mind can turn
and soften, and my songs will be softer
and lightly weight the air.

I’m not a poet. I’m not an English teacher. I’m not a literary scholar. Maybe this poem or any of the others mean something totally different than I think. I don’t think it matters, though. What matters is that we pushed ourselves to do something different, that we worked outside of our comfort zone, that we really tried to learn and understand.

But it’s not enough. I need to do more next year. I need to do more for my students. To let them know that their history and their culture matter. To let them know that they matter. To help us all learn to be better, more tolerant, more understanding, more generous in spirit.

This was a risk. I don’t know if I did a good thing. I don’t know if I made a mistake. I badly want feedback, but I’m also terrified that I sent a message I didn’t intend to send. It’s uncomfortable sometimes – teaching – but it’s worth it for those moments. Those powerful moments when twenty-five thirteen- and fourteen-year-old students devote their attention to listening to a classmate read a poem. I hope that I made a difference.

Reflections on The Classroom Chef

Reflections on The Classroom Chef

Take risks. More than anything else, that’s the message of The Classroom Chef by John Stevens and Matt Vaudrey. It’s 2018. We owe it to our students to do better than just teach the same lesson we’ve been using. We owe them better than life in a textbook universe. We owe them more than just lectures and practice. We owe our students a meaningful classroom experience that will help them develop understanding and not just procedural fluency. We owe them more.

Take risks. I told this to my students when we returned from winter break. I told them that I planned to take risks this semester to make class more interesting, to help them find meaning in what we’re doing, and to allow them to learn and refine academic and life skills.

Take risks. Grades don’t matter. Test scores don’t matter. Coverage doesn’t matter. Standard algorithms don’t matter. Compliance doesn’t matter. The book doesn’t matter. The pacing guide doesn’t matter. Standards don’t matter.

Take risks. What does matter? The students in front of you right now. Their thoughts and ideas and energy and interests and passions and enthusiasm and suggestions and questions and feelings and understandings and beliefs and knowledge and motivation and … What matters? Their future. What matters? They do.

Take risks. We owe our students the best education we can possibly give them. John and Matt understand this. They understand that we need to change if we really want our students to grow. They understand that it’s not enough to do the same old thing – even if it has been effective in the past. They understand that we need to keep pushing forward lest we end up going backward. They understand that education in 2018 can’t look like education in 1950 or 1990 or 2005 or even in 2017. They understand that students need us to value their engagement, their thinking, and their future.

Take risks. The Classroom Chef offers a ton of great ideas and useful advice. But beneath all of the stories and suggestions lies one simple message – take risks.
