## First Day Plans

This school year I will be teaching four different courses – Geometry (2 sections), Discrete Math, Calculus Honors, AP Calculus BC. My Twitter feed is being bombed with first day plan posts, so I will jump in here as well. Sitting by a pool, so this I’ll not be lengthy.

Note that our first day has 25 minute classes and a long community gathering.

In Geometry I have started the past three years with a dramatic introduction to the handshake problem. It generates some fun guessing and conversations right off the bat. We are also able to revisit this problem in various forms during the year. I think it is a winning first day activity.

In our Calc Honors class I will take students out in the hallway with some wheels chairs. I will have a segment of hallway measured for length and we will have some races pushing these chairs down the hall. This, I hope, will generate some conversations about average speed tat we CAN calculate and all sorts of instantaneous information that we cannot. This should be a basis for distinguishing between secant and tangents over the first days/weeks of the course. Plus, it is fun to run down the hall!

In Discrete I am going to use a fantastic quote that I read this summer (you can find it here )  I think that this might generate some fun research and some fun conversations about magnitude.

In Calculus BC I want to start with a deep dive into a conversation about linearization and approximations. I have gathered some fun ideas on twitter about how this conversation can unfold. I hope it leads to quite a bit of noticing and wondering about accuracy and when/why that accuracy falls apart.

I am kind of embarrassed that I forgot one of the best highlights of the TMC17 conference. A while ago I received a tweet from John Golden (@mathhombre) asking if we could have a video chat about calculus. He was putting together an idea about a resource for his calculus students and wanted a variety of perspectives. Well, after a series of attempts we finally settled on a group chat on Saturday night. It was pretty loud everywhere on the lobby level so I offered my room as a quiet refuge. I had the joy of chatting about calculus with John, Jasmine Walker (@jaz_math), Edmund Harriss (@gelada), and David Butler (@DavidKButlerUofA) You can find our conversation here

I was SO flattered to be asked to do this and it was such a blast to chat with these four lovely and brilliant people. I told John on Sunday that I was jealous of his students. My apologies for having this wonderful experience slip my mind when I posted earlier today.

## TMC17 Reflections

Beginning my reflections on the latest TMC experience (I am fortunate enough to have been for the past four years) I find myself focusing more on the personal experiences in ATL than the mathematical ones. That being said, I LOVED the presentation on base-8 math by Kent Haines (@kenthaines) and I am beginning to shift away from my strict aversion to multiple-choice questions based on Nik Doran’s (@nik_d_maths) advice in his morning session.

Last year in Minneapolis I allowed myself to dwell on the fact that there were social happenings that I was not part of. I KNOW that this is an inevitable fact when any large group of people gather together. It was especially true since we were housed in different places AND I was not equipped with technology that allowed me to tune in to everything going on around me. It was not until November of this past school year that I had a smart phone. Looking back, I KNOW how foolish this was. I had lovely dinners and chats with folks. I went out within hours of arrival to a lovely pub with Brian Miller, his school colleague Wilson, and Henri Picciotto. I had an amazing talk at dinner one night with Dave Sabol, who is kind enough (or crazy enough) to be one of the hosts for TMC18. I had fantastic math conversations and life conversations and came home a richer person than I arrived. However, I have allowed myself to dwell on what did not happen.

This year, armed with a smart phone (that I did not end up using much at all, really), going to a hotel where (almost) everyone was staying, and being in a city I knew, I went in with an agenda for myself. I knew I would be away on Friday night visiting an old high school buddy who was also my first college roommate. I made a commitment to myself. I was not going to hang around and see what happened about lunches or dinners. I sent out a tweet on Wednesday night inviting folks to join me at a restaurant I found called Smoke and Duck Sauce. Wednesday night ended up with a large gathering at Rose and Crown that was a great deal of fun. I sent out a call on the #tmcplans for Thursday night and had a great dinner with a fun group. On Friday night I had a lovely meal with my old friend and his family and returned to the hotel to stumble in on a deeply meaningful conversation with a fantastic group of friends. I was drawn over by seeing Brian Miller and Jasmine Walker (a couple of my favorite TMC pals) and ended up awake far later than I intended to be as a sprawling group of folks in a corner of the lobby bar really dug down deep on some personal and professional issues in a sensitive and vulnerable way. My had was spinning as I went to be. On Saturday night, I sent out another call on #tmcplans and ended up at Cowfish with a dozen folks. A LOVELY meal, great conversation, laughs as we celebrated a fake birthday, and a great sense of belonging and satisfaction as people piled into my rental car there and back on each evening. I went along to a breakfast at Waffle House based on an open invite. I had lunch with different folks every day at the campus of Holy Innocents. I had a quiet breakfast by myself the first morning of the conference enjoying southern grits and getting my head focused for the upcoming adventure.

I am not going to dip my feet into the mini controversies that came up during the week about hashtags and inclusion. I just want to say that I know that when I took it upon myself to be responsible and engaged in the community I enjoyed myself far more than when I was passive about it. Even though I also enjoyed myself then!

Of course, the social aspect and the connections are only part of the reason to come to TMC. There is also some sweet math to be experienced. My morning session with Nik thinking about hinge questions has me seriously re-thinking my bias against multiple-choice questions and recognizing their value if they are thoughtfully constructed and are treated as important data points in understanding what my students understand. His energy, intelligence, and good cheer made the morning sessions well worthwhile. I had two moments of mathematical epiphany during the week. On one of David Butler’s afternoon sessions he introduced us to some of his puzzles from 100 Factorial. I worked in a group with Jasmine, Joe Schwartz, and a new pal Mo Ferger on a fantastic problem called skyscrapers (you can find a link here!) We worked doggedly, and successfully, on this problem. On an afternoon session with Kent Haines I worked on some problems and pattern finding in base eight arithmetic. Again, working with some folks in the room (I wish I could remember who!) we poked around and noticed and wondered and fought the frustration that many of our students must routinely feel as we tried to find a comfort level in this realm of mathematics.

After a busy, happy, and rewarding three days with my #mtbos family in Atlanta, I am now relaxing with my (much smaller) family on vacation counting down the days to the new school year. I know I will still have some of this energy fresh in my mind in a few weeks. The challenge is to keep it fresh in my mind all year.

## How Important is the Silence?

At our church this past Sunday one of the members of the congregation gave a thoughtful sermon about what it means to keep the sabbath. At least that was the primary framework of her conversation. Much of the time was spent talking about learning to take care of herself and what that looks like. Is it listening to a sermon at church? Is it staying home to garden instead? Is it taking a long walk? Is it listening to an inspiring TED talk? Naturally, there is no universal answer for this, but it sure got my mind spinning thinking about what it means for me to take care of myself.

I have engaged in a number of twitter exchanges recently sharing podcast tips. I have become hooked on a number of them and I listen while walking/jogging outside. I listen while I am on my Airdyne in the basement or on the treadmill in the basement. I was listening to Marc Maron and Randy Newman talking to each other just half an hour ago while eating my breakfast here in the airport (I am heading to TMC17 today!) Last month I was visiting my last hometown in New jersey and I went for a long stroll in a park where my wife and I used to walk as a pit stop on the way to pick up our son from day care. At the urging of an old friend – again, through a twitter conversation – I unplugged for that walk. For about 30 minutes I was strolling through this park, remembering cool fall days walking with my wife, listening to the sounds of the park and the neighborhood. It felt energizing. However, I have to admit I have not unplugged like that for another walk or run since. As energizing as that silence felt, I also recognize that I draw a great deal of energy from taking in ideas/content/entertainment through my podcasts. I tend to have music on in my house most of the time I am there. My wife and kids bought me a hammock for Father’s Day. I always bring a book with me to the hammock. I wonder (worry?) if I am just hiding from silence and from being with myself this way. I justify it by recognizing how much I enjoy being tapped into a number of conversation. By recognizing the joy I find when something I hear about that seems brand new suddenly starts popping up all around me. I am excited that I have been spending more time and energy listening to new music again due to my summer DJ gig (which I hope will turn into a fall one as well!) However, I also worry that this is making my time and mind feel even more crowded. I worry that I should put that aside and be quiet. I worry that I should be goofing around with my daughter at home more often instead of curling up with a book while she plays in her room or watches a show on TV. I justify this by thinking that I am ‘taking care of me’ by indulging in books, music, podcasts, exercise so that I can be better at helping others – wife, kiddos, students in the fall, etc.

I am in the last few weeks of summer here and I have taken on a teaching overload for the upcoming year. I’ll be teaching five classes with four different preps. This is on top of being a department chair. I think that the looming concern about what this will feel like has also made this past Sunday’s sermon more meaningful. I mentioned earlier that I know that there are no universal answers to this question, what I am worried about is that I am not clear about what the answer is in my particular situation.

I work better when I set specific goals. Last fall I was waking up early three or four times a week and going for long walks before coming home to wake up my wife for coffee in the morning. I think that I want to commit this fall to picking one day each week, Monday feels like a good choice, to making sure that I go out on this walk with no earbuds. Take a long walk or jog with the silence of an early morning in my ear. Keep my mind clear thinking about what the upcoming week holds. By putting this in writing, I am convinced that I am more likely to carry through with this plan. At the very least, I will feel vaguely guilty or embarrassed if I cannot carry through on this commitment. Not a BIG game changer, but at least this feels like a start. I will check back in on this after the school year is in gear.

As always, feel free to join in the conversation through comments here or by poking at me over on twitter @mrdardy

## So, What Kinds of Change?

In my last post I wrote about our department’s terrific two day workshop with Henri Picciotto. One of the major decisions we made based on the time we spent together is that we have decided, as a whole department team, is that we will allow test corrections on all tests in our department. Before I dive into the format of the decision we made, I want to include a couple of important links here with other points of view about assessment policies. The first comes from a new twitter contact Steve Gnagni (@Steve_Gnagni) who shared this interesting document written by Rick Wormeli (@rickwormeli AND @rickwormeli2 for reasons I am not sure I understand!) called Redos and Retakes Done Right and the second is a link Henri shared gathering together some of his ideas about assessments.

Or, I should say I was totally excited about it. I know that there are different ways to view this process and the meaning of it. I know that we decided that events that we call tests are subject to this correction policy. We decided (for a number of reasons, some more ideologically defensible than others) that short quizzes were not subject to this policy. I know that I will be balancing this with graded take-home problem sets and on these problem sets I always encourage collaboration. So, when Steve Gnagni shared the article above, I found myself doubting some of the decisions we made. I found old reactions about grades being really seriously challenged and I began to doubt whether our decision on process is ideologically pure enough. I also know that this is progress. I will be sharing Rick Wormeli’s article with my team in the fall and we will be checking in with each other on how we feel about the impact of this new process.

I want to thank Henri again and to thank my new twitter pal Steve Gnagni for sharing their ideas. As long as we are all willing to keep questioning ourselves we can continue to help our students grow.

## A Change is Gonna Come

A little background info to the story I am about to relay.

Our school has operated for quite some time with a static schedule of 7 classes that meet every day and in the same order. Our class times vary a bit based on assemblies and special events with the primary class times being 40 minutes, 45 minutes, or 50 minutes. There is certainly a comfort level with having a steady rhythm. As a teacher, I am pretty sure what my 8 AM class will be like after a few weeks. I know who is sleepy in the morning, I know who is a bit frisky right after lunch. Unfortunately, I also know who will be late to first period and who plays a sport each season so they will be missing my last class pretty frequently.

Is your school is looking at structural changes to your schedule? Are you  wrestling with structural conversations about curriculum? Are you looking for high quality, focused professional development time with your math department? If you answered yes to any of these questions, I cannot recommend Henri Picciotto highly enough. I am not his agent, I am not a paid actor here, I am simply a happy happy teacher who has benefited greatly from the time my department spent with Henri two weeks ago. My team seems much less anxious about the changes in our life and they seem clearer on curriculum and instructional goals. I am convinced that our students will benefit greatly from this time we spent together.

## Brief thoughts on Graduation Weekend

Yesterday was graduation day here at my school. I am pretty sure that this was my 31st high school graduation ceremony – mine and 30 years as a teacher. I think that I did not attend my little brother’s graduation for some reason or other. At least, I do not remember it if I was there.

There are always waves of joy/sadness/pride/regret that run through me on graduation days. I saw some alums and had lovely conversations with them that made me happy. One joked that his Calc 3 class at McGill was easier than his BC Calc class with me. I think that this is probably a compliment in the end. Some students went out their way to find me to express gratitude while others certainly showed no inclination that I was on their list of people that they wanted to talk to on graduation day. Every year ends with the good feeling that there are students who I have made connections with in or out of the classroom. Young people who appreciate that I was part of their lives here. Every year also ends with the disappointment that there are some students I was not able to connect with. Students who were frustrated by my class, did not connect with my goals or my classroom strategies. Students who will not remember me fondly – if/when they remember me at all. This is both a cause for sadness/frustration and motivation to recharge soon when I think about next year and plan for how to reach a broader set of students where they are.

## Fixed an Error

Apologies to anyone who tried to follow the links on my last post. I am still learning the ins and outs of google forms. I have gone back and corrected the problem, so you should be able to view the question form if you are interested in doing so.

## Seeking Wisdom and Guidance from my Students

In my last post I was reflecting on some of the important differences between students based, in part, on their age and experience. Thinking about that since the post, I also realize two other important differences between my Geometry classroom and my AP Calculus BC classroom. In our school, Geometry is the last class in our curriculum where there is not a distinction available for Honors credit. Starting in Algebra II, kids get sorted out and those students who don’t see math as ‘their thing’ or simply want to back off a bit in my subject area can. This creates rooms, in both the honors track and the non-honors track, where there is more homogeneity in interest level. In my Geometry class there is a wide divide in interest/background/ability/age in the same classroom. In my Calculus class there is a more level playing field. I think that this goes a long way to explaining some of the data I received this week. The second major difference is that, due in part to the fact that new students enter our school at every grade level, there is a more noticeable age difference in my Geometry class than in either of my other classes. I have students from grades 9 – 12 in Geometry. In my other classes I have only juniors and seniors. I think that this leads to a real difference in the social environment in these classes.

Our school asks each teacher to administer course evaluation forms to all students. The format that the school developed asks many questions, almost all of them Likert scale questions with space included for short answer explanations. I appreciate the emphasis our school places on seeking student input but I have developed the feeling that too many students just glide down the page circling essentially the same answer to questions and they are reluctant to write much down. Some have stated that they are concerned that their teachers recognize their handwriting, but I suspect that most just aren’t that terribly invested in the process. We spoke about this extensively in our last department meeting and one of the conclusions we reached was that we will administer some form of course evaluation at the end of each of our trimesters next year. After all, if the goal of the feedback is to improve the students’ experience, then telling me what to change in May does not have much weight to students who are leaving my classroom in another week. I am kind of embarrassed that I have not come to this conclusion by myself, but at least I am learning, right? I did do two things differently this year. I wrote my own surveys for each of my three classes and I administered them electronically in the hopes that I would get a little more detail from my students. If you are interested, you can see my surveys here for Geometry , here for my Discrete Math elective , and here for my AP Calculus BC class . There are not many differences between them, but I did tailor a bit for differences in the classes.

Here are screenshots of the pie-charts generated on the Google forms. First the response of the Geometry students to the group seating decisions I made this year.

Here is the response of the Discrete Math Students. One of my sections was small enough that we stayed in one group together all year. The other section had rotating groups for two of the three terms of the year.

Finally, here is the image for my Calculus team

I think that there are some interesting things happening here. I had the chance to talk to my Discrete class and they were willing to share some interesting insights. I think that the comfort level with rotating groups is closely tied to a combination of comfort level with the material and with each other. My BC kids all came from AB the year before and many of them were in the same AB sections. They know each other and they are confident with math. My Geometry kids are a wide blend of ages (grades 9 – 12) and backgrounds (a good number are new to our school this year) so there is not as much cohesion. My Discrete kids come from all over the place. Some just finished Algebra II, some had a year of Precalculus. Some had part of a year of Precalculus before switching over. Some are brand new to our school. There is a good degree of camaraderie in the classroom, but there is not a consistent feeling that everyone is on the same page. This is something I need to be more aware of and a piece of classroom culture that I think I can help improve next year. During my conversation with them yesterday, we focused on two topics. The first was group assessment – I have some group quizzes and we have a group final each term. We had all eleven people working together and they seemed to appreciate that, but felt that I needed to trim the number of questions since debate/discussion took some time. Duly noted. They also seemed to largely feel that rotations are okay, but maybe they should change after more than a week. I am thinking that they may change at the beginning of each new chapter. With our new schedule at school next year, this might work well.

I feel good looking back at this year. I took the plunge and moved from static seating in small groups to dynamic seating that created broader networks of communication among my students. I personalized the feedback I ask for and I feel that my students took these questions seriously and shared some remarks with me in a pretty honest way. I have a lot to think about this summer (as always!) but I feel that I am moving toward becoming the teacher I want to be.
