The Computational Thinker's Classroom - Workshop Video

I ran a workshop on computational thinking at the Vietnam Tech Conference this past March. My goal was to give teachers some new ways to think about classroom tasks and the deliberate use of computers to do what they are good at doing.

The general vibe of my talk was consistent with what I've said here in the past. Some highlights:

  • We should be using computers to do the tasks that computers do well. This frees us up to do those tasks for which we are well suited.
  • Insisting on basic skills as the entry point for learning is an easy way to put students on the sidelines. Computers are often how we as professionals answer questions that are important or interesting to us. We should help students understand how to use them in the same way.
  • Spreadsheets, databases, and visual models like Desmos and Geogebra are great entry points for computational thinking. You don't have to be a coder, a mathematics or science teacher, or a technology expert to build these activities for your students.

The video is here:

If you want to do the first three activities yourself and see other resources from my workshop, visit goo.gl/vsT2G6. There is a fourth activity on the page that is mentioned at around 24 minutes in the video that is linked there too.

As always, I'd love to hear what you have to say.

Reminders for Myself

Students can go online and see more than enough videos about completing the square to require me to be the one to write steps for them.

Students can (and often do) seek tutoring outside of class to learn shortcuts to solving the most common problems.

Students can look up code that has been written before.

Students can memorize when I ask them not to do so, and choose not to memorize when I want certain knowledge to be locked in long term memory.

Students can pore over a textbook, often alone, and learn everything that might be tested on an exam. They might understand how to make connections on all sorts of scales, levels, and manners of organization with no input on my part or on the part of another student.

Given that all of these things might be true:

  • My classroom should be a place that maximizes the potential a whole group of human brains all trying to learn something new in the same space. The things we do together should respect the fact that we can do them together.
  • The focus in my classroom should be on the difficult parts of learning. Experiencing and overcoming confusion is a natural part of learning. So is trying something, failing, and learning why that something led to failure. Having good people around during this process lessens the blow. That is why we are there together.
  • I am an expert in identifying the ideal next step in the learning process for an individual, a group, or a class. I am an experienced learner. I've been there. Sharing and calling upon that experience is how I add value.
  • I should outsource instruction for those students that can learn without me. I can teach directly when students need me to do so, but this is not as frequent as I might first think. I should provide as many different resources as possible and encourage students to choose the ones that would best help them make progress. Pride when I am that resource, and disappointment when I am not, are not important. The classroom is not about me.

The structures and systems should not punish students for actions from the first list. The structures and systems in the classroom should support the goals in the second list.

Making Sense of Stories

I love stories. They capture my attention in pretty much any situation in which I find myself, and I don't think I'm the only one. Story telling has always been an easy way for me to capture the attention of students in my classroom. Each story I tell usually shares a snapshot of my life outside of the classroom. In calculus, I tell the story connecting integral calculus to the way I pester my mom by drinking glasses of chocolate milk with increasingly smaller spoons. I tell graduating seniors my story of never feeling like high school was actually over until I experienced eye-lid twitches immediately after my flight took off at the end of the summer en-route for my new college home.

I use stories as pedagogy too; there is something satisfying about talking about number sets as a series of successive inventions introduced to address the mathematical needs of humanity. Counting sheep, signed integers for money, measurement and immeasurable numbers. My intention in doing so has been just, or at least it has felt just up through fifteen years of teaching. The idea is that we start with the most basic elements of mathematics by counting, and then just add complexity as we attempt to account for the rest of what we see in the universe. If we start with the basics, and if we build up our understanding continuously from the basics all the way to the highest levels of mathematics, we are doing right by our students. As our age or number of years in school increases, the complexity increases alongside to match. This, after all, is often what traditional mathematics course sequences have always done.

The concept I confront fairly frequently is how much I disagree with the inverse of this progression. That if we do not start with the basics, then we will not get students to understand increasingly more complex material. This is most often the conversation around students that have gaps in their understanding. We can lament those gaps as teachers, and though my colleagues have always sought ways to help students across them, they can lead to conversations that make me uneasy. "Student A is not ready for X. He can't factor a quadratic."

The main reason I object to this argument is that it leads to a number of issues around course offerings and their structure. I believe curriculum most frequently becomes bloated because of the demands of courses that come after them. Colleges demand X from high schools, so high schools add to their course offerings to match those expectations. This means that high schools demand Y from middle schools, middle schools expect Z from elementary, and so on. I've argued about this mismatch of expectations about the basics across the levels in a previous post.

I am not just concerned about this in the context of mathematics.

My high school US history class twenty years ago made it to the civil rights movement in the 1960s. One could argue that understanding the 1960's requires that we understand the entire story of what happened before it. Maybe we could have moved faster over the entire year so that we could have made it closer to present day, but I don't think my teenage brain would have been able to handle a higher speed.

Must a physics class always start with one dimensional kinematics? Must we do projectile motion algebraically to really understand it?

Stories usually have a beginning, a middle, and an end. If the story of school mathematics always starts with algebra, has geometry and more algebra in the middle, and the end is calculus, students will always be waiting for us to push them forward through the curriculum because as teachers we aknow the story. In traditional timeline based history, we know what happens next because it's the next day or month in time, or the next page in the book. In chemistry, everything is made of atoms, so we have to first build atoms from subatomic particles, then combine elements into compounds, then combine compounds into reactions, and so on.

The other thing that really good stories do, however, is start exactly when and where they need to start. This is not always at the beginning of the action, when things are simple and easy. Good stories expect the audience to trust the medium to provide necessary details along the way. There is backstory, there is foreshadowing and detail and confusion - all deliberately baked in to capture our attention. This is not to say that our job is about entertaining our students. I believe that making sense of what students see in front of them is more important than adhering to a traditional notion of what is basic.

We don't have to construct a car from bolts and sheet metal in order to learn to drive it.

We don't have to understand that water is a polar molecule to understand that it freezes into ice. At some point though, understanding this might help us understand why it ice floats. It's our job to make that knowledge necessary.

The pathways we craft for our students do not have to start at the very beginning of all knowledge or content. They can start with an interesting starting point that leads to questions. They will be confused at first to figure out where they are, what is going on. This is an opportunity to teach knowledge to help students work their way out of this confusion. We can start at the big picture level and dig deeper as increasing complexity demands it. I think teachers broadly understand this on the individual class level, but that this often gets lost in conversations of curriculum or course sequence. We need to be doing more to build our courses to have more experiences like this.

I really think those of us in content based subjects need to talk to our colleagues that teach art. Their courses are often equally dense and skill based, but they take an approach to learning and analyzing that is much more along the lines of being plopped down in an alien environment, shown something novel and unique, and being expected to ask questions. What do you see? How does this make you feel? What questions do you have about what you see? Why did the artist make this choice? How did the artist achieve this result?

There are basics to be taught, but they rarely need to be the starting point.

This is where the biggest shifts in my understanding of this job have occurred over the past fifteen years. Stay tuned.

New Moves: Working With and Within

As I said in my previous post, things have been really busy over here. I made the deliberate choice to turn my attention away from blogging and toward some projects that I’ll be sharing as they develop this summer.

One reason was the realization that I felt I was connecting more to teachers outside my building than I was within. I decided to spend more time this semester walking to have one-on-one conversations with my colleagues. Some of these conversations were around the courses we taught together. Others were from the position of my role this year as department head in mathematics. And still others were about connecting on a personal level with the talented people on the high school team.

Here are a few of the ideas that have arisen from these connections:

  • We are designing a collaborative office space for teachers in math, science, and technology, along with a separate quiet space for deep work and focus.
  • We began a discussion around common language, skills, and curricular connections between mathematics, science, and social studies. Ideas like graphing, precision, and command terms could be presented more uniformly in our classes. This might mean that students don’t have to memorize three different expectations about scaling axes or understandings of the terms “compare and contrast”. We also tried some new approaches to curriculum such as population growth, and flexible ways to connect instruction where it was natural to do so.
  • We explored the need for clear but flexible grade descriptors. This lets students understand what grades mean in terms of their learning beyond a collection of points or fractions out of one hundred.
  • We started looking into a more flexible approach to courses that goes beyond an assumed traditional sequence of knowledge. The story of mathematics from counting to algebra to Calculus, for example, does not always best serve the many public relations issues associated with our subject.

Discussions within the walls of our school to think differently and plan more as a team was a valuable way to spend some of my prep time. I continued to seek balance in the time I spent on school projects and projects at home. This meaningful work did not happen by accident. It takes a commitment of time, and a subsequent decrease in time devoted to other things.

This has resulted a redefinition of what I need from (as well as what I can best provide) my personal learning network. The ideas I get from Twitter and reading blogs still keep me energized and encouraged to try new things in my classroom. Sharing what I do myself has admittedly taken a back seat. I’m looking for ways to help shine light on the great things that others are doing in our school. I’m inspired by what my colleagues have helped students do over the course of the year, and I want others to be inspired with me.

There is a lot more to this change in focus. More on that soon.

From the Archives - Notes Before A Move

It has been quiet over here on the blog. You haven’t missed anything - things are fine. I’ve been running on many cylinders and focusing on some big projects in the works.

I’ve been thinking a lot about the concept of school and why we do what we do. I was reminded while looking through some old files that I had written a long-form article back in the summer of 2010 before moving overseas to teach for the first time. It was an attempt to make sense of the many lines of thought I had about the public school system in general after teaching in the Bronx for six years, and one year at the KIPP NYC College Prep high school. I was not blogging at the time, and did not have a good place to put this beyond emailing it out to some close friends.

I still think it represents my long held belief that we are at our best when we choose to talk and listen to one another. Demonizing one another does little to make progress.


We need a reliable and effective educational system. This fact is obvious to most people. Politicians know that making sound bites that state this fact is necessary to win elections. The difficult part comes when individuals attempt to define precisely what they mean by 'reliable' and 'effective'.

When informing people that I am a teacher, responses are always delivered with a healthy mixture of three main themes: acknowledgment of the difficulty of the job, its importance, and a statement on how teachers are not valued in today's society. What follows is also like clockwork: a sip of a drink, a statement about the “other hand” - at least teachers get summers off and can go home at three. Sometimes I explain other realities of the job (such as grading or the intricacies of lesson planning.) Other times I just nod and accept that most people lack an understanding of how much work is involved in good teaching (both inside and outside of the classroom) or in developing into a better teacher after each day's set of experiences.

As has been said many times before, good teaching is both an art and a science. Teachers will then admit (often when out of hearing range of administrative judgment) that good teaching is an iterative process. There are good days and rough ones, engaging lessons and unintentionally boring activities, and even times when a potentially good lesson fizzles because it meets a particularly fickle developing mind too soon after lunch. While principles of psychology, child development, and principles of cognition can shed significant insight into what should work well in the classroom, teachers are expected to also use a great deal of intuition and experience to figure out what will work best to help students achieve their learning goals and meet standards. Students are, after all, people, not machines.

It is also fairly obvious that the concept of accountability in the educational system is here to stay. This is not in itself a bad idea – given that most people agree about the importance of education, distinguishing an effective educational system from a less effective one is necessary to iteratively reach a system that works well for its students. The devil is again in the details. Teachers, administrators, political leaders, professors, statisticians – they can all be as different in their approaches as there are students in the New York City educational system.

I will now admit one of my own mistakes as a teacher: I have punished an entire class of students for the actions of a few. It never gets me the results I want, and when I have thought about it afterward, it never makes sense. Many students do the right thing on a regular basis – why yield control of the class to the few that least are able to handle it? These individuals often need to be managed in a different way, time, or setting. When I do handle things in this individualized way, as difficult as it can be with a larger class, it always works out in a more positive way for both myself and the involved students.

The logic of a one-size-fits-all solution does not make sense in education. So why is it so common? Our community grapples with the difficulties of reconciling the practical side of accountability with the ultimate goal of educating youngsters to become informed and responsible citizens every day. And yet, we frequently see solutions or policies that attempt to reduce complexity to the singular innovation, classroom structure, or educational program that will fix all of the system's problems.

Furthermore, many people in our field strive on a regular basis to paint a picture of other players as being woefully inadequate, incompetent or immoral, even though these may be a small fraction of the whole. Principals complain about veteran teachers that refuse to try new things and are difficult to fire because of union rules. Teachers that join the profession through alternative routes cry foul when some principals seem concerned only with pass percentages or when a veteran teacher does not take the time to grade nightly homework. A public school parent wonders why his son's new science teacher, who cannot control a class, replaced one with more experience who was fired because he refused to write a whole new curriculum without being paid for the time. A community member might see charter schools as elitist and unfairly funded, but a student attending a charter might just as easily wonder why she could not get the personal attention she needed from her old neighborhood school.

The fact is that the entire spectrum of humanity, from crooks to tragic idealists, are present in our system. There is also a substantial population on the other side of the coin. There are parents that want to help their children with homework but do not know how. There are new teachers that are willing to work long hours to write lesson plans, but do not know that the secret of teaching addition of fractions could be revealed in a minute long conversation with a veteran. Furthermore, there are veteran teachers that have legitimate concerns about policy changes based on their past experience, but their voices are drowned out by others labeling them 'naysayers'.

To frame the debate by assertions from one group on how much another group cares (or does not care) about children and their education is completely unproductive – all of us want the best for the children in our system. There are many innovative, talented, and passionate people that want to work hard in a system to help children make meaningful progress in developing skills for future success. To also claim, however, that moving forward is impossible because of a minority is just as illogical. There are ways to include everyone in the process and discuss how to lead students to develop good character traits and be prepared for their own academic goals.

The primary flaw in the current administrative efforts is in looking for the system that will work for everyone, rather than the people that will make the system work for all. Teachers are often told to differentiate instruction, which means to optimize classroom activities to help and support students of all skill levels to reach specific learning goals. All students are not the same, and neither the paths they follow to to reach their academic and character goals, nor the support they need along the way, will be the same. Why do we look for solutions that are not differentiated in this manner?

The energy crisis will not be solved by just solar power, or wind power, or biofuels. It will be solved by solar power and wind power and biofuels and conservation and the development of new technologies and the adaptation of some old ones. There is no silver bullet; there is, however, a combination of different energy sources that will together bring us a more stable climate, a more stable economy, and a more sustainable lifestyle for people around the world.

Along the same line of reasoning, just creating a system with more charter schools will not solve our problems if the human capital needed to run them is not developed concurrently. Changing the system to one that closes failing schools and replaces them with the same administrators and teachers and conditions that led to its downfall is not the answer. More testing is not the answer, but eliminating testing will not work either.
We need to better support neighborhood schools and the people that work within them and have a system that supports charter schools. We need a union that works to support and protect teachers that might agree with the goals of the administration, but not the methods they use to reach them. We need to study both effective charter schools and effective traditional schools for the successful elements they share. We need to innovate to find ways to emulate the positive aspects of both and invest in people to do the extra work necessary to adapt and run these systems in effective ways. We need to find ways to unite the experience of veterans with the energy of new teachers and alternative certification programs like Teach for America. We need not to spend late nights reinventing the wheel while veteran teachers are eager to be heard.

An earnest effort to invest in and support the people that make these systems work is the other crucial piece that is necessary for the system to improve. Systems that depend on human talent and ingenuity (as education does) cannot be duplicated by simply copying the structures produced by effective educators. One educator may make use of a word wall effectively to improve his or her students understanding, but simply insisting that every classroom have a word wall does not make every educator effective.

A podcast made earlier this year from This American Life, a production of WBEZ in Chicago, described an interesting collaboration between Toyota and GM called New United Motor Manufacturing Incorporated, or NUMMI. Workers from GM traveled to Japan to tour the Toyota plants and explore the structures in place. Many of the workers that traveled were experienced machinists that had spent years doing the same thing over and over again in the plant, and were disillusioned by the mechanical nature of their job. The success of the Japanese system relied on the observations and ideas of individual workers along the assembly line working together and alerting each other when there was a problem. When the assembly line stopped because of a problem, a playful tone would play throughout the factory so that individual workers would know which station needed assistance. Floor managers would work to divert workers to assist the troubled station until the issue was resolved. The end result of this system was a higher productivity, higher quality product, and increased pride on the part of the workers constructing the cars. The American workers were energized by the visit and left Japan inspired and ready to apply the lessons learned to the factory floor back in the United States.
Initially, management was excited to call upon the new energy of the returning workers. These managers attempted to copy the exact structure of the plants in Japan, down to the alignment and arrangement of the individual machines on the shop floor. They opted not to invest the same energy and money in establishing the systems that supported the people in the assembly line. Penalties were instituted for halting the assembly line, and workers would snitch on each other to enhance their reputations with managers. In the end, the same problems experienced by American plants before the collaboration still occurred. What remained was an unhappy workforce, and a factory that looked just like the plant in Japan, but with none of the productivity.

Cookie cutter solutions appeal to the preference for simplicity built into the human mind. They are shortcuts, which are dangerous if used without understanding what is cut out for the sake of speed. Charter schools do a lot of good for the students that attend them, but that does not mean we need many more charter schools - there are both effective and ineffective ones. Research that shows that Teach for America corps members can help students make progress on a level comparable to teachers with more experience, but that does not mean we need more Teach for America corps members and fewer traditional teachers.

These represent individual pieces of the solution to the difficulty facing us in reforming the educational system to work better for its students. The key is to figure out how to make the most of all of the different talents and capabilities of all of the people in our system to do this. This is not about stating which group is the greatest obstacle to progress. The system will only improve if we figure out how best to inspire and support the people working within it. Each of us knows what is at stake.

New Moves: Discretized Grades

Two of the courses I teach, AP Calculus AB and IB Mathematics SL year two, have clear curricula to follow, which is both a blessing an a curse. While I primarily report standards based grades in these courses, I have also included a unit exam component that measures comprehensive performance as well. These are old fashioned summative assessments that I haven't felt comfortable expelling from these particular courses. Both courses end with a comprehensive exam in May. The scores on these exams will be scaled either to a 1 - 5 (AP) or a 1 - 7 (IB). The longer I have taught, the more I have grown to like the idea of reporting grades as one of a limited set of discrete scores.

Over my entire teaching career I have worked within systems that report grades as a percentage, usually to two digit precision. Sometimes these grades are mapped to an A-F scale, but students and parents tend not to pay attention to those. One downside to the percentage reporting system is that it implies that we have measured learning to within a single percentage point. Let's leave out the idea that we should be measuring learning numerically at all for the moment, and talk about why the idea of discrete grades is a better choice.

As a teacher, I need to make sure that I grade assignments consistently across a course, or across a section at a minimum. I'm not sure I can be consistent within a percentage point when you consider the number of my students multiplied by the number of assessment items I give them. I'm likely consistent within five percent, and very likely consistent within ten. I am also confident in my ability to have a conversation with any student about what he or she can do to improve because of the standards based component of my grading system.

One big problem I see with grading scales that map to letter grades is the arbitrary mapping between multiples of ten and the letter grades themselves. As I mentioned before, many don't pay attention to the letter at all when the number is next to it. Students that see a score of 79 wonder what one thing they should have done on the assessment to be bumped up by a percentage point to get an 80, resulting in a letter grade of a B. That one point also becomes that much more consequential than a single point raising a 75 to a 76.

Another issue comes from the imprecise definition of the points for each question. Is that single point increase a result of a sign error or a conceptual issue that is more significant? The single digit precision suggests that we can talk about things this accurately, but it is not common to plan assessments in such a way that these differences are clearly identified. I know I don't have psychometricians on staff.

For all of these reasons and more, I've been experimenting with grading exams in a way that acknowledges this imprecision and attempts to deal with it appropriately.

The simplest way I did this was with final exams for my Precalculus course last year. In this case, all scores were reported after being rounded to the nearest three percentage points. This meant that student scores were rounded roughly to the divisions of the letter grades for plus, regular, or minus (e.g. B-/B/B+).

In the AP and IB courses, this process was more involved. I decided that exam scores would be 97, 93, 85, 75, and 65 which would map to 5-4-3-2-1 for AP and 7-6-5-4-3 for IB. I entered student performance on each question into a spreadsheet. Sometimes before, and sometimes after, I would also go through each question and decide what sort of representative mistakes I would expect a 5 student to make, a 4 student, and so on. I would also do a couple different scenarios of scoring at each level to find how much variation in points might result in a given score. That led me to decide on which cut scores should apply, or at least would suggest what they might be for this particular exam. Here is an example of what this looks like:

At this point I would also look at individual papers again, identify holistically which score I thought the student should earn, and then compared their raw scores to the scores of the representative papers. If there was any clear discrepancy, this would lead to a change in the cut scores. Once I thought most students were graded appropriately, I added the scores into a Google script to scale all of the scores to the discrete scores.

This process of norming the papers took time, but it always felt worth it in the end. I felt comfortable talking to students about their scores and the work that qualified them for that score. The independence of these totals from the standard 90/80/70/60 mapping between percentages and letter grades meant that the scores were appropriate indicators of how they did, regardless of the percentages of points. Students weren't excited to know that they couldn't figure out their total point percentage and know their score, but this was not a major issue for them. Going through this process felt much more appropriate than applying a 10*sqrt(score) type of mapping to the raw scores.

In my end of semester feedback, some students reported their frustration that they would receive the same score as other students that earned fewer points. I understand this frustration in principle, but not in practice. The scores 92.44% and 91.56% also receive the same score under the standard system by rounding to the nearest percentage. I think in the big picture, the grades students received were fair, and students have also reported a feeling of fairness with respect to the grades I give them.

I'm in favor of eliminating the plus and minus designations from letter grades. They are communication marks and nothing more, and I would rather communicate those distinctions through written comments or in person rather than by a symbol. These marks are more numerical consequences of the percentage grade scale than they are intentional comments on student learning, and they do more harm than good.

New Moves: Reassessment

I’ve been a bit swamped over the course of the semester and unfortunately haven’t made the time to write regularly. There were lots of factors converging, and nothing negative, so I accepted that it might be one of the things to slip. This is something I will adjust for semester two.

I’ve written in the past about my reassessment systems and use of WeinbergCloud to manage them. I knew something had to change and thought a lot about what I was going to do to make my system more reasonable, something the old system was not.

At the beginning of the year, I sat down and started to reprogram the site...and then stopped. As much as I enjoyed the process of tweaking its features and solving problems that arose with its use, it was not where I wanted to spend my time. I also knew that I was going to teach a course with a colleague who also was planning to do reassessment, but I was not ready to build my system to manage multiple teachers.

I made an executive decision and stepped away from the WeinbergCloud project. It served me well, but it was time to come up with a different solution. We use Google for Education at my school, and the students are well versed in the use of calendars for school events. I decided to make this the main platform for all sorts of reasons. By putting my full class and meeting schedule into Google calendar, it meant that I could schedule student reassessments by actually seeing what my schedule looked like on a given week. Students last year would sign up to reassess at times when I had lunch duty or an after school meeting because my site didn’t have any way to block out times. This was a major improvement.

I also limited students to one reassessment per week. They needed to email me before the beginning of any given week and tell me what standard they wanted to reassess over. I would then send them an invite to a time they would show up to do their reassessment. This improved both student preparation and my ability to plan ahead for reassessments knowing what my schedule looked like for the day. Students liked it up until the final week of the semester, when they really wanted to reassess multiple times. I think this is a feature, not a bug, and will incentivize planning ahead.

I recorded student reassessments in PowerSchool in the comment tab. Grades with comments appear with a small flag next to them. This meant I could scan across horizontally to see what an individual student had reassessed on. I could also look vertically to see which standards were being assessed most frequently. The visual record was much more effective for qualitative views of the system than what I had previously with WeinbergCloud.

The system above was for my IB and AP classes. For Algebra 2 (for which I teach two sections and share with the other teacher) we had a simpler system. Students would be quizzed on standards, usually two at a time. Exams would be reassessments on all of the standards. Students would then have a third opportunity to be quizzed on up to three of the standards of each unit later in the semester. Students that had less than an 8 were required to reassess. This system worked well for the most part. Some students thought that the type of questions between the quiz and exam were different enough that they were not equivalent assessments of the standards. My colleague and I spent a lot of time talking through the questions, identifying the types of mistakes on individual questions that were indicators of 6 versus 8 versus 10, and also unifying the feedback we gave students after assessments. The system isn’t perfect, but students also were all given up to three opportunities to be assessed on every standard. This equity is not something that I’ve had happen before in my previous manifestations of SBG.

On the whole, both flavors of reassessment systems were much more reasonable and manageable, and I think they are here to stay. I’ll spend some time during the winter break thinking about what tweaks might be needed, if any, for the second half of the year.

A Note on Vertical Planning

Many teachers justify including Topic X and skill Y on a high school syllabus because colleges and universities expect students to have mastered topic X and skill Y for their courses. Not because Topic X is interesting or skill Y is necessary for success at the high school level, but because the next step expects it.

I wonder if the set of X and Y for high school teachers matches the set of X and Y for universities. I wonder how often university professors and high school teachers (and middle school or elementary teachers for that matter) get together to discuss this.

I wonder which of our assumptions about what the other thinks matches reality.

 

 

New Moves: Design Principles and Generosity

During the summer, I attended the academy for the new class of Apple Distinguished Educators in Melbourne, Australia. Among the workshops I attended was one from Stephen Hider on design principles.

Given the obsession I've grown over the past few years with design, much of this was nothing new. Alignment, proximity, repetition, and contrast were all old friends. The one that seemed new, perhaps because of a new name, was generosity. This principle means that an element of a design has been enough space around it such that it is, in Stephen's words, "able to breathe." Removing distracting elements around the focus allows a person to think about it in isolation, and with more clarity than would otherwise be permitted without the added space.

The idea is something that I've been thinking about for a while, inspired principally by Dan Meyer's exploration of ways that digital media provides ample opportunities to do things much differently than when confined by the economic costs of paper. (For more on this, see his talk titled 'Delete Your Textbook', linked here.)  I wrote in my previous post about changing the organization of my course away from a daily handout and toward individual tasks, each a separate linked PDF file. Individual problems or questions are presented on their own with space around them, when appropriate.

Here's an example of the contrast between a handout from last year's Algebra 2 course, and a page from a task this year.

The old:

...and the new:

The amount of paper I use in my classroom is reduced, and is much more deliberate. I still will print out individual pages when I really want to do so. The fact that I have freed myself from the demand that there be a handout for every class means I can be much more thoughtful about this. I can focus more on how I visually present ideas that are connected to each other rather than trying to make sure that everything fits in a manageable area of a page. The intention was not to be paperless, but I am finding that this small change has led to students being more likely to take time to pause between tasks and reflect on the work they have done before moving on. Nothing I have done previously has had such an effect.

New Moves: Course Organization

Ever since switching to standards based grading, many components of my courses and classroom organization have come into alignment with my philosophy of teaching. Ideally, these align perfectly, but the realities of time and professional responsibilities can shift this alignment. My beliefs on assessment, on effective learning activities, and on using the classroom social space effectively have all come into sharp focus when my grade book aligns more closely with the learning that goes on.

There is one notable exception to this alignment.

My class notes and handouts, and therefore much of my courses, have always  been organized around days of class within a unit: Unit 1 Day 2 handout, Unit 3, Day 5 handout, Unit 5 review, etc. This has made it easy for someone that misses day three of unit two to know what precisely was missed during the day. It makes it easy for me to see how I organize the days within a unit. This is how I've done things for the past fourteen years.

In courses organized around standards like mine, a student should be able to see the development of content related to a standard from start to finish. The progression of content within a standard allows students to see ideas grow from simple to complex. A student that wants to review standard 1.1 needs to know which days covered material related to that standard. While identifying this is an important high level task, it doesn't help struggling students know where they should look to know what ideas relate to a given standard.

This was the main reason I have organized all of my course materials this year by standard. Here's a screenshot of a portion of my IB Mathematics SL Year 2 page on Moodle:

Each problem set or activity is organized under the learning standard under which it applies. When I post notes about a given problem or activity, it is put underneath the problem set to which it applies. Some days we work on content related to multiple standards, but I parse that information into different parts and organize it that way. When we do work that spans multiple standards, that work is posted above the standards and identified as such.

In the past, students have consistently asked to know the details of a given standard - now they can look for themselves for what types of problems relate. The materials are also generally organized in increasing level of difficulty or abstraction, so students know that the more challenging content is listed further down below the standard. I've also found that the types of activities I have students do is more diverse. I might send students to watch a video, do a curated list of Khan Academy exercises, or write a response to a prompt. Previously, the class handout was the one source of truth for what students should be doing at any one time. Now the materials have been expanded.

There is still a preferred order or menu of activities that I prescribe for each class. I post this as an agenda and refer students to it when it looks like they need some direction:

Students have reported that they have more freedom to do things at their own pace under this system.  We may not finish all of the material from Unit 2, Day 3 - that just means that the material can be moved to the next day's agenda. Naming the tasks in this different way makes it easy for a student to move ahead or work independently. I can spend my time during the class helping those who need it and challenging those that are making good progress.

I really like how this has transformed the spirit of my classroom. I admit that the organization of the course into standards is artificial - the real world is not organized this way. Being deliberate and communicating how class activities serve the learning standards, and what relates to big picture unit-wide challenges, helps students understand the balance between the two. I know this isn't the final answer, but it does seem to be a step in the right direction for my students.
