Cost-Benefit Analysis

It’s the start of a new school year and one of my personal goals this year is to get back into blogging. Reflection is a key part of my pedagogical practice and this blog serves that purpose. Another reason is that we are in the beginning stages of a research project in which blogging and journaling will be part of the data collection process. So I’m following the advice of my good friend, Carl Oliver, and just pushing send.

Well not quite yet, I will at the end of the post. I promise. But, before I do push send, I wanted to discuss one of the most vulgar, wicked, fiendish, and ear-splittingly foul four letter words in the educational lexicon, time. Teachers and students are constantly asking for more time for a variety of things. How often have we heard things like: “I need more time to finish the problem.” “I need more time to assess the students.” “I need more time for self-care.” Time is at a premium in education and everyone is looking for how to maximize it.

To illustrate this point, I’d like to share a story. This year I am working with a new assistant teacher and she has just begun her educational career. We began the year by using John Stevens’ Would You Rather instructional routine. Our plan was to use this routine as a warm-up and then move on to another activity, however the lesson she had created was going so well that we decided to continue it with an extension that asked the students to create their own Would You Rather prompts. Afterwards, she asked me why we didn’t move onto the next activity as planned and the only phrase that I could think of was, “Cost Benefit Analysis.” In our classroom to support students with a variety of disabilities, we try to focus solely on the goal of the lesson. The goals of this lesson were for students to think critically, explain, justify, and express themselves. Teachers make an average of 4 instructional decisions every minute and each of those choices should be in service of the instructional goal of the lesson. So each decision is analyzing the cost of time with the potential benefit towards the instructional goal. This instructional routine was allowing students to construct viable arguments and critique the reasoning of others while also providing us, the teachers, with some valuable formative assessment of their mathematical skills and levels of thinking. The benefits far outweighed the cost of scrapping the other planned activity. (Sorry Dan!)

I am also often asked about levels of prompting and how much support teachers should provide students with disabilities. The answer is another cost-benefit analysis. Factors to consider in your cost-benefit analysis are the needs of the student, the cost of independence and the potential benefit towards the instructional goal of the lesson.

Our speech & language therapists facilitated a professional development session on how the levels of prompting relate to language input and output. They created and shared this graphic that everyone found very useful.

To alleviate the gravity of each of these cost-benefit analyzed instructional decisions, we implement instructional routines as a way to “temporarily hold some things [in the classroom] constant while working on others.” So of the 270,000 decisions that my assistant teacher and I will make this year hopefully, as David Wees states, instructional routines allow us to focus our decision-making on the most important things, the students and the math.

#ShadowCon18

DYXIOeSWsAEsp8j

Since its inception in 2015 as a rogue addition to the National Council of Teachers of Mathematics (NCTM) Annual Meeting and Exposition in Boston, ShadowCon has provided teachers, teacher leaders, and academics with inspiration and motivation through the intriguing and passionate calls to action presented by educators of every stripe.

In the inaugural event, Laila Nur, Tracy Zager, Elham Kazemi, Kristin Gray, Michael Pershan, and Christopher Danielson presented their calls to action that spanned from giving the right kind of hints to solve math problems to using your sense of humor to create a safe and enjoyable space for your students in math class.

The talk that I gravitated towards in 2015 was Tracy Zager’s Breaking the Cycle. Zager, author of Becoming the Math Teacher You Wish You’d Had, contrasts how elementary school teachers describe mathematics with the descriptions of mathematicians. Spoiler alert: the mathematicians’ descriptions are drastically more positive. I was inspired to share word clouds Zager created with my colleagues after I asked them about their own opinions of mathematics. I also felt motivated to engage with Tracy and other educators around the country on the ShadowCon website.

The next year, at the 2016 NCTM Annual Meeting and Exposition in San Francisco, I was asked to be a live tweeter for Brian Bushart‘s fantastic #ShadowCon16 talk called, Make Your Own Kind of Music. The presence of live tweeters is an important innovation established by ShadowCon hosts Dan Meyer, Mike Flynn, and Zak Champagne in order to provide live access to as many people as possible, even those who are not in attendance but who can witness the event live on twitter.

This year, at the 2018 NCTM Annual Meeting and Exposition in Washington DC, I had the privilege to be invited to speak at #ShadowCon18! Instead of reading a description of my talk entitled, “Presume Competence: Don’t Leave Your Expectations At the Door, Raise Them!” Watch it for yourself!

Go ahead, I’ll wait…

Thanks for coming back! Now that you’ve watched my talk you’re probably so ready to presume the competence of your students, but you may be wondering what to do next.

ShadowCon has you covered!

This is how ShadowCon is unlike any other conference experience. Each speaker from this year’s event will be continuing the conversation via email to delve deeper on the subject of their talk. Go to bit.ly/shadowcon18 to signup for one of these #ShadowCon18 email threads. The speakers will be sending discussion prompts, activities, and reflections to each email thread over the next month or so.

Models of Disability

Last week, we had our first parent/teacher conferences of the school year. During the conferences we discussed the importance of self-advocacy for students with disabilitiesthat mathematical proficiency is more than procedural fluency, and how hard it can be for a parent of a student with a disability. This time afforded me the opportunity to reflect on some of the reading I’ve done lately including some books more specifically about disability.

41Q8rT75xaL._SX331_BO1,204,203,200_

One such book is Disability Studies and the Inclusive Classroom by Susan Baglieri and Arthur Shapiro. Baglieri and Shapiro present an easily digestible version of how disability is currently situated in the world of education and society. Baglieri and Shapiro go into detail about two models of disability that influence our work with students with disabilities in the school setting. They are the medical model and the social model of disability.

Our Kids Are Not Swiss Cheese!

This blog post was co-written with Rachel Lambert and available on both blogs.

big_is_swiss_cheese_bad_for_you.

A couple of years ago, Rachel Lambert and myself were talking about how students in special education are conceptualized. We were sick of hearing about the “gaps” and the “holes” in our student’s learning. One of us, (probably Rachel!), blurted out – “Our students are not Swiss cheese!” We laughed, since this summed up for us how learners with disabilities are both over-analyzed and under-educated, always seen as the sum of their deficits, not their strengths. What follows are two recent experiences we’ve each had in which the idea of thinking of students as Swiss cheese has resurfaced.

Beginning the School Year with a Productive Disposition

There are many ways to start the school year in math class, some are better than others. Building a culture of risk-taking, mistake-embracing, hard-working, respectful students who view themselves as mathematicians is no small feat.

Why is this important? Because research says that the way student’s view themselves in math class can predict future attainment levels in math class. Also, developing a productive disposition towards mathematics is a key to any student’s success in school. So should we focus on developing classroom norms or beginning the year with math tasks? Tracy Zager, author of Becoming the Math Teacher You Wish You’d Had, weighs in.

Whether we choose to start the year by jumping into a rich task on the first day, or by engaging in a reflective study about what it means to do mathematics, or by undertaking group challenges and conversations to develop norms for discourse and debate, we must be thoughtful about our students’ annual re-introduction to the discipline of mathematics.

So this year in order to re-introduce our students to math, we developed a collection of activities specifically chosen not only to engage students meaningfully in mathematics, but to also develop a productive disposition to mathematics as well.  Continue reading

We Need YOU!

The weeks after the NCTM Annual Meeting and Exposition are usually a time of personal professional reflection and consideration about the future direction of the organization itself.

During Congressional recess, Senators and Representatives go back to their communities and hold town halls to hear the issues that are important to their constituents.

In Tracy Zager‘s recent blog post reflecting on her own experience at the NCTM conference, she says the following [emphasis added]:

From where I sit, the merger with The Math Forum, the emphasis on #MTBoS representation on all NCTM committees, the MTBoS keynote in Nashville, and the support of our fringe events like Game Night and ShadowCon are meaningful. I’m all for pressing NCTM to be what we need it to be. But I’m also all for recognizing the big shifts made over the last few years. Change comes faster within the (unstructured, unregulated) #MTBoS than it can within the (highly structured, institutionalized) NCTM, just by the nature of the beasts. But good change is happening nonetheless.

The blog post you are reading right now focuses on the idea of “#MTBoS representation on all NCTM committees.” Recently, Carl Oliver, Tina Cardone, and I began two-year terms on the NCTM Publishing committee. Our first committee meeting will be held soon and we’ll all have more specific information afterwards, which we’ll be sure to share. So, in an effort to begin with transparency, this particular post is meant to be a kind of digital town hall.

NCTM_R_LogoandName4C_L

As #MTBoS constituents, please share your answers to these (or other questions) in the comments section…

  • What issues are important to you regarding NCTM publications (magazines, books, and journals)?
  • How do you currently use NCTM publications in your professional life (in or out of the classroom)?
  • How can NCTM publications be the most useful to you in your professional role?

To be completely honest, as #MTBoS committee representatives we cannot promise to address everything, but we’d like to begin this adventure knowing what’s already on YOUR mind!

Pi Day (with minimal mention of digits)

Today, we celebrated our belated Pi Day! It was delayed due to inclement weather…

Though my #MTBoS friends were there to comfort me in my time of need!

Our spring trimester focus is always financial literacy. So, we spent most of last week researching recipes, planning for a shopping trip, going to the bank, shopping for ingredients, and making pies. Yes, I said it. We made pies for Pi Day, sue me! Now, finally the time had come to eat our pies, but first…we had to do some more math!

First we reviewed of some of the digits of Pi, highlighting that when rounded to the nearest hundredth it matches the numerical date of March 14th, which is subsequently known as “Pi Day” for this reason. I also wore my Pi shirt, which gives the students an opportunity to see that there are A LOT of digits in this number known as Pi and that I’m a nerd. We did, however, skip the traditional digit memorization activity for several reasons including working memory and tedious boredom.

Instead we estimated, explored, and discovered the circumference formula with our pies and some string.
