The last two years I have been working for New Visions for Public Schools, mostly remotely but with some trips to New York City to run workshops and do school visits. During that time, I’ve kept careful track of the work I have completed as you can see above.

With my colleagues, we completed an Algebra I course which includes:

• 5 videos to support specific instructional strategies
• 7 formative assessment lessons
• 8 units and 7 unit plans
• 7 initial tasks, 7 end-of-unit assessments
• 10 videos of instructional routines enacted in the classroom
• 24 Big Ideas
• 123 tasks to support instructional routines
• 125 interleaved, spaced, retrieval practice assignments
• 138 pages of notes for teachers
• 664 pages of student-facing materials (link 1, link 2)
• An add-on to help manage 1200 typeset Regents problems

These resources were built with support for multilingual students and students with disabilities baked in. We read and incorporated cognitive science in the development of these resources. We released all of these resources under a Creative Commons license so that teachers could feel free to download and adapt these resources for their students. In order to support teachers in using this curriculum, I personally spent over 650 hours preparing and enacting workshops for teachers over the last two years.

My work with New Visions is wrapping up soon and so I am reflecting on the work we completed. I regret that our Geometry and Algebra II courses are not yet done, but I feel pretty proud of what we accomplished together regardless.

 

I have been involved in the professional development of teachers since 2006 and in that time, I have learned a lot about how to support teachers in their professional growth.

WHAT I USED TO DO

My very first presentation for teachers was a 45-minute workshop on Open Source Technology in Education. It was horrible. I talked for 45 minutes straight without taking or asking any questions or giving teachers a single example they could use in their classrooms. Two of my colleagues fell asleep.

But, I improved. The next year, I ran the same workshop in the school computer lab and gave teachers access to a bunch of programs they could use, then at the end of the workshop, I pointed out that all of these programs were free because they were part of the open source movement.

Neither of these two approaches leads to a significant change in teacher practice. In one case, I gave teachers a whole lot of why they might want to use a teaching tool without the how, and in the other case, teachers got a lot of how they can use the software, but with limited pedagogical approaches, and very minimal emphasis on why teachers might want to use open source tools. Teacher engagement was significantly higher with the second approach though…

WHAT I DO NOW

The structure of a workshop that I run now is quite different than what I used to do based on what I have learned, especially from Amy Lucenta and Grace Kelemanik. Here is what I do if I am lucky enough to be running a day-long workshop.

1. I start with an overview of the objectives of the workshop and give teachers the agenda for the workshop. If I have enough time, I ask teachers to think about their own goals for the day, describe them to a partner, and then gather and record some responses from the room.
2. Next, I give teachers a brief summary of why we are experiencing what will experience together and how it is helpful for students.
3. I then engage teachers in a teaching and learning experience with teachers playing the role of students and myself playing the role of teacher. I try to make this experience as authentic as possible by encouraging teachers to stay in role and to think and speak like a student. If they think a student would do something, I ask them to be that student. If the goal for the workshop is to introduce an instructional routine and I have enough time, I model the instructional routine two or three times so that teachers can see what remains the same each time the routine is run and what changes based on the task and the student responses.
4. We then unpack the experience together so that teachers can name the parts of the experience and describe how those parts are helpful for students.
5. I give teachers get structured planning time at this stage so that they can look at some sample resources in more depth and make decisions about how they will use those resources. Usually, during this planning time, teachers work through some example mathematics using a planning template. While teachers work, I circulate around the room, both to see how they are planning together and to find some volunteers for the next part of the workshop.
6. The most powerful part of the workshop is when teachers who have volunteered play the role of teachers in a rehearsal of the work experienced earlier. A rehearsal is very much like the original experience teachers had towards the beginning of the day, but during a rehearsal, we can pause the action, rewind if necessary, and experiment with different instructional moves. The goal of a rehearsal is to get every teacher considering teaching together not to evaluate and give feedback to individual teachers.
7. I close the workshops with a reflection activity and gather further feedback from teachers, usually with a standardized online form or with index cards.

One important element of the day-long workshops is that they are aligned to the curriculum we have developed so that teachers have access to resources they can use to continue to implement the ideas they learn during the workshop routinely through-out the year.

WHAT DOES RESEARCH SAY?

Here are some key principles my colleagues at New Visions for Public Schools, Angel Zheng and Simran Soni, found when they looked at research on effective teacher professional development.

Professional development for teachers should:

1. Be of sustained duration and focus. In particular, the research reviewed found that more than 14 hours of professional development had a positive and significant effect on student achievement, while those with less than 14 hours did not (Editorial note: This number of hours is probably an artifact of the specific studies included, the necessary duration probably depends on a variety of factors),
2. Include a heavy focus on providing ​evidence-based research​ about the subject before providing specific strategies to address the content,
3. Rooted in subject matter​ focused on the student as a learner to have the highest impact on student achievement,
4. Include time for the teacher to interact with the procedure taught​ and practice how they would apply it in their own classrooms. This may include an emphasis on teachers experiencing the material as a learner, not an educator,
5. Couple professional development opportunities with a new curriculum or pedagogical tool. Simply providing a new resource without any additional support does not work, it is necessary to provide resources with explicit support,
6. Provide explicit resources​ to assist teachers in planning while others offered time for teachers to ask for support from them and from the other teachers.

According to Zheng and Soni (Internal Research Review, 2017), “a set of researchers (Yoon, Duncan, Lee, Scarloss, & Shapley, 2007) looked across 1,300 studies that address the impact of professional development. They then narrowed the studies down to nine that met What Works Clearinghouse (WWC) Standards. Across these nine studies, professional development for teachers increased their student achievement by 21 points (out of 100).”

You can probably see that the professional development structure I typically use aligns well with the research. It also is very engaging for teachers who frequently report strong satisfaction with workshops that I and my colleagues run, which as it turns out, is rare in professional development. According to this survey on teacher professional development, workshops are only ranked slightly behind professional learning communities as teachers’ least favourite professional learning activity.

While I used to think good presentations were mostly about format and delivery, now I am convinced that the structure of the workshop and the infrastructure that exists to support the work teachers do after the workshop are the most critical elements for creating professional learning experiences that actually help teachers and consequently, their students.

What I would change

One area that is currently completely missing from my work with teachers is the ability to visit teachers before and after workshops to see the impact of the professional learning experiences I provide. Since the primary goal of the professional learning I support is to give teachers instructional tools they can use with their students, without a feedback mechanism that incorporates what they actually do with students, I feel sometimes like I am operating in the dark.

 

Here are four videos that represent the perspectives of students with various learner characteristics. Imagine you have these four students in your class. How might you support them?

These four students have different needs but some discussions of students with special needs treat all of these students as being identical. For example, I recently got asked how to best support the students in a school with special needs. My first response, which I kept to myself, was to figure out what their special needs are and meet them.

My next response was to share these three resources:

1. Use instructional routines as part of core instruction. These routines embed supports that aim to improve the odds that all students understand the mathematical ideas being shared. Further, the use of routines reduces the cognitive demands students (and coincidentally their teacher’s cognitive demands as well) often have around making sense of frequently changing instructions and structures for working with other students. When these demands are reduced, students have more cognitive space available to make sense of mathematics.
2. Many of the strategies embedded within the routines can be used outside of the instructional routines. These strategies are also described in detail by Grace Kelemanik and Amy Lucenta in their book, Routines for Reasoning.
3. This interactive table has suggestions aligned to specific characteristics of the learner. For example, for a student who is hard of hearing, using non-verbal communication such as pointing at what is being discussed increases the odds students can follow along.

Instead of making assumptions about what students with special needs can or cannot do, determine what the specific needs are of the students you have, and then make your best effort to meet those needs.

There is a problem with the third set of resources as they essentially follow a diagnostic model — figure out the problem and then assign a cure, but many advocates for students for special needs want us to stop considering the students broken, and instead think of them as whole human beings who have needs, just like everyone else. I’m actually not sure how to provide helpful advice and resolve this issue comfortably.

Additional resources:

• The Teacher Education by Design project has additional instructional routines that may be more appropriate for younger students.
• Here are more suggestions for students who are hard of hearing.

 

I recently had someone ask me this question on Twitter and I think it’s an important question!

How do you plan a succession of lessons for a maths topic, say multiplication or division?

As it turns out, I’ve spent the last 4 years planning sequences of lessons as part of the curriculum work I do with a team of math specialists, so I have some significant experience with this task.

 

Decide what success looks like

The first step in our process was to decide on a logical sequence for the units of study for the year. Given the amount of time we had to devote to curriculum development six years ago, we basically decided to outsource this part of the process to the Mathematics Design Collaborative, but there are a lot of ways to decide on an order to units and to some degree, the choices are arbitrary. It’s what comes after that is critical but this allowed us to decide on an initial apportioning of the content standards to specific units.

We started with assigning a formative assessment lesson from the Mathematics Assessment Project to each unit, essentially deciding on “what does it look like to be successful in the mathematics of this unit?” first before outlining the mathematics of the unit. This decision, to work backwards from the end goal, is described in more detail in Grant Wiggins and Jay McTighe’s book, Understanding by Design.

 

Decide what a unit looks like

My colleague, Russell West, created this Unit Design Schematic to outline the general structure we intended to build for each unit.

 

Align mathematical tasks to the unit

6 years ago, we had a partnership with the Silicon Valley Mathematics Initiative, and they have literally hundreds of rich math assessment tasks aligned to high school mathematics. I printed out all of them for middle school and high school and we put them on a giant table in our office board room. My colleagues and I then sorted all of the tasks into the units where we felt like they fit best (or in some cases to no unit at all). Our experience suggested that tasks are a better way to define the mathematics to be learned than descriptions of mathematics.

Once we had descriptions of the units, formative assessment lessons, and tasks for each unit, we decided an initial task and a final task for each unit. The goals of the initial tasks were to preview the mathematics for the unit for students and teachers and to give students and teachers a sense of what prerequisite mathematics students already knew. The goals of the end of unit assessments were to assess students understanding of the current unit and to give students and teachers a sense of the end of year assessments, which in our case are the New York State Regents examinations.

 

Be really specific about the mathematics to be learned

With all of this framework in place and a structure for each unit defined, we then did all of the tasks we had grouped into each unit ourselves, ideally a couple of different ways, and made lists of the mathematical ideas we needed to access in order to be successful. Essentially we atomized each task to identify the smallest mathematical ideas used when solving the task, but we were careful to include both verbs and nouns and created statements such as “describe how independent and dependent quantities/variables change in relation to each other.”

By chance, we watched this talk by Phil Daro on teaching to chapters, not lessons, and decided that we needed to group the atomized ideas we had generated into chunks and we labeled these chunks “big ideas”.

 

Group the mathematics into meaningful chunks

The next part of the process took a long time. We wrote descriptions of the Big Ideas and the evidence of understanding that would tell us if students understood the big idea for the week. This evidence of understanding was essentially the result of the atomizations that we had previously created, grouped together into week-long chunks. The process took a while because we wrote and rewrote the evidence of understanding statements so that our entire team and a sample of the teachers we worked with felt like we understood what the evidence of understanding meant.

For example, the first Big Idea of our Algebra I course is “Rate of change describes how one quantity changes with respect to another” and our evidence of understanding, at this stage in the course, include statements like “determine and apply the rate of change from a graph, table, or sequence” and “compare linear, quadratic, and exponential functions using the rate of change”. The last Big Idea of our Algebra II course is “Statistical data from random processes can be predicted using probability calculations” and the evidence of understanding for this Big Idea includes statements like “predict the theoretical probability of an event occurring based on a sample” and “compare two data sets resulting from variation in the same set of parameters to determine if change in those parameters is statistically significant”.

Once we had this evidence of understanding mapped out, we also checked to see whether important ideas would come back throughout the course in different forms and looked to make sure that deliberate connections between different mathematical representations were being made. This way students would get the opportunity to revisit ideas, make connections between topics, and have opportunities to retrieve information, frequently, from their long-term memory.

We also revisited the alignment of the New York State Learning Standards to our units, and ended up adding standards to some units, moving standards around in some cases, and writing some clarifications about what part of a standard was addressed when during the course.

 

Design tasks for each chunk of mathematics

Now, finally, we were ready to make tasks. Well, actually, in practice we started making tasks as soon as we had a sense of the Big Ideas and then occasionally moved those tasks around when we had greater clarity on the mathematics to be taught. But once we had nailed down the evidence of understanding, we were able to map the evidence of understanding for a week to specific activities, essentially creating blueprints for us to design our tasks from, since each of the evidence of understanding statements were linked to observable actions of students.

We ended up with a final product we called a Core Resource. It’s larger than a single lesson but it’s not just a random collection of lessons either. It’s a deliberately sequenced set of activities meant to build toward a coherent larger idea, while attending to two practical problems teachers encounter frequently – that of students forgetting ideas over time and needing a lot of time to build fluency with mathematical representations. Here is a sample Core Resource for Algebra II.

 

Summary:

In hindsight, the most important parts of this process are:

• to work backwards from the goals at the end of a year and the end of a unit,
• use tasks as examples of what success looks like,
• be really specific about what the mathematics to be learned is,
• chunk the mathematics into meaningful pieces,
• and then finally design tasks that match the mathematics.

For multiplication and division specifically, I would be tempted, as much as is possible, to frequently interleave the two ideas together, after identifying the many constituent mathematical ideas that together represent these large mathematical ideas. For example, if students learn to skip count by twos, five times, to find how many individual shoes are in five pairs of shoes, I would want to work backwards fairly soon from there to I have 10 pairs of shoes, how many pairs do I have, so that students can more directly see these two operations as opposites of each other.

In 4 months, the grant that funds the consulting on curriculum and professional development I do with New Visions for Public Schools ends and unfortunately, it does not look like a new grant is on the horizon. Consequently, with blessings and support from my colleagues at New Visions, I am looking for either another consulting contract or full-time employment.

The work I do is extremely varied. This past month I:

• Developed two weeks worth of mathematics curriculum for classroom use as part of this collection of resources,
• Designed and ran two workshops for teachers on using mathematics curriculum aligned to Geometry and Algebra II curriculum,
• Created interactive dashboards using Data Studio to display historical data from the NY Regents exam,
• Wrote a script to automate responses to the thousands of Google Doc share-requests my colleagues were receiving,
• Wrote a script to automate conversion of Google Docs into PDFs,
• Created two videos examples of classroom teaching in action (example),
• Double-checked that typesetting we had done is correct for thousands of math and science questions for this Google Sheets add-on,
• Supported a new assistant principal to make plans for her math team,
• Other smaller tasks related to supporting 80 or so secondary schools with their mathematics instruction.

Here is an overview of my professional skills.

I live on a small island off the coast of British Columbia, Canada where I grew up. It is beautiful and we are settled. If it is absolutely necessary, I will live apart from my family for at least part of the year, but ideal work for me would allow me and my family to remain where we are. I don’t mind traveling if it is necessary for work.

I’m looking for work that makes use of my skills and allows me to grow and continue to be challenged to learn new things.

You can help by:

• Giving me encouragement and cheering from the sidelines,
• Suggesting opportunities and organizations that will meet my needs,
• Sharing my resume with people and organizations that you think may be interested in someone with my skills.

 

As some of you probably know, I’m one of the lead designers on an open source math curriculum. Today I had an interaction that reminded me of a key benefit of open source curriculum.

In a traditional curriculum model distributed either on paper or via PDF, Hannah would have to either print and then painstakingly correct the errors above by pasting over them or use some likely-painful-to-use PDF editing software to fix these errors.

We distribute our open source curriculum via Google Docs and as a result Hannah can just make a copy of the document, make the edits she wants, and then print the resources for her students. Hannah is also legally able to do this because our curriculum is licensed specifically for adaptations.

Since each resource we create has its own page on our website (the resource Hannah describes is here), Hannah was able to comment on a specific document and I was able to respond to her transparently.

There are drawbacks of using Google Docs. For example, it is not currently possible with our curriculum to print out the entire set of student handouts. This is a fairly frequent request we get from teachers but we don’t know yet if the loss of editability is worth the increased ease of printing resources.

It would be helpful for me to know what other pain-points exist for teachers when adapting and modifying curriculum for their own classroom use, especially given that a high percentage of teachers make adaptations to curriculum they are given. If you were in charge of how someone shared curriculum, what would make it as easy as possible for you to make thoughtful changes to that curriculum?

 

I have been to perhaps a dozen national conferences and to two dozen or so regional conferences across the United States and Canada. With the exception of one or two of these conferences, I regret having ever attended.

My regret stems not from finding the conferences uninteresting or not enjoying meeting people face to face that I had only ever met previously online, my regret stems from the fact that I think these conferences are fundamentally immoral when our world is in crisis.

Conferences that draw people from all over a country or all over the world require participants to fly to a single destination. This results in thousands of people flying to destinations whom otherwise would not be flying. Unfortunately, flying in an airplane carries with it a huge carbon footprint. One flight across a continent or across the Atlantic has roughly the same carbon footprint as using a car for an entire year.

Here is an aggregated list of conferences across the United States. I counted 1374 conferences occurring next year, each of which may have many hundreds to thousands of participants. That’s potentially millions of flights each year for people to attend these conferences.

Maybe these conferences would be worth their carbon footprint if people learned something significant from them that changed their practice. But my experience is that this is not true. In most cases, I suspect that if a few people took two days off from work and read the same good book about teaching and then planned together based on that book, they’d get as much (or more!) out of those two days than they learn from attending 10 different scatter-shot presentations. Sessions are just not typically long enough to result in tangible learning and presenters often just don’t know the actual audience of teachers they end up with well enough to plan a session that meets those teachers’ varied needs.

It’s true that once in a while I’ve attended sessions that really made me think. A few years ago, I attended the NCSM and NCTM conferences back to back, focusing only on sessions on instructional routines, only attending sessions by a group of people who worked closely with Magdalene Lampert on these routines. That was a hugely valuable conference for me! But 1 hugely valuable conference out of the 18 or so I have attended does not justify the environmental cost of these conferences.

I think that we might be able to replace national conferences with the following and to some degree, this may produce similar learning for participants:

• Virtual conferences: Sessions are run via web conferencing software. These are ideal replacements for non-interactive (or minimally interactive) presentations that dominate most conferences.
• Book study groups: Grab 2+ friends and take two days off from work. Everyone reads the same book on day 1, on day 2, everyone convenes to first describe what things they learned and then make plans to implement some of the suggestions.
• Run smaller regional conferences: I know everyone wants to see Fawn Nguyen, Jo Boaler, or Dan Meyer speak at conferences, but I believe there is lots of local expertise in most parts of the world that could be drawn upon instead.

This year I cancelled my presentations at the NCTM annual conference, the NCTM regional conference in Seattle, and CMC South in Palm Springs. I went to one conference that I could drive to up at Whistler, the Northwest Math conference (it was really good). I do not intend to submit proposals to conferences in the future that require me to fly to the conference.

 

Geometric constructions are amongst my favourite things to teach in Geometry. Why? I see each geometric construction as a puzzle to be solved and I love watching children solve puzzles and share their solutions to those puzzles.

Puzzle #1: Given a line segment, draw a circle with its radius as the line segment.

Many constructions build on earlier constructions so that as students figure out how to do earlier constructions, they build the pieces they need to figure out more complex constructions. Further, more complex constructions embed all sorts of opportunities for practicing earlier constructions.

Puzzle #2: Draw another line segment with the same length as the given line segment with an endpoint on either A or B.

The invention of dynamic geometry software, like Geogebra, means that students can learn these earlier constructions without their early challenges using a compass and straightedge interfering with their ability to learn the mathematical ideas behind the constructions.

Puzzle #5: Draw a line segment that is exactly three times the length of the given line segment.

It is super helpful for students to have their prior work with constructions visible for themselves as examples to work from, and so once students have figured out how to do a construction with the digital tool, I have them transfer their construction to paper (ideally in their notebooks for reference) so they can access it later.

Puzzle #10: Draw three overlapping circles on the same line such that two of the circles have their centers on the middle circle.

Another advantage of the digital geometry tools is that you can provide partial constructions for students. This way students can work on the part of the construction that is new. This doesn’t give students practice with the earlier part of the construction but it is a subtle way to give hints to students for particularly complex constructions.

Puzzle #11: Use the circle below to help you draw a regular six-sided shape (regular hexagon).

When a student shares their constructions with the class, I usually call up a volunteer that is not that student to come up to the front of the room and perform the construction, following the verbal instructions from the first student. This means that the pace of the construction is likely to better match the pace other students can follow or copy the construction which leads to more students understanding the construction. After the construction is complete, I can ask another student to restate the instructions while I annotate important features of the construction.

Puzzle #17: Construct an octagon (regular 8 sided shape).

The last few constructions, I provide the least amount of support for students since a goal of mine is to see if students can do these constructions independently. However, note that in the instructions for the constructions, I try to make sure that the language of the constructions isn’t a barrier for my students.

Constructions #1 through #17 are available in this Geogebra book and a paper copy of these instructions is available as Lesson 2 of this Core Resource.

Let me know if you have any questions and please share other ideas you have about introducing students to constructions.

Great teaching is more than putting good tasks in front of students because a good task enacted with terrible pedagogy is still terrible teaching. While I think hardly any teachers are terrible, every teacher can be better than they are.

I see a lot of sharing of tasks, games, and activities via Twitter and blogs, but I see much less sharing of pedagogical strategies teachers would use with those tasks, games, and activities, which means a lot of people are losing potential opportunities to learn about pedagogy.

Often people share routines like Which One Doesn’t Belong or Connecting Representations which on the surface look like pedagogical strategies, but while the names themselves are somewhat descriptive, they aren’t sufficient to understand the routines they describe.

That’s part of the reason we created videos of the two main instructional routines embedded in our curriculum, Contemplate then Calculate and Connecting Representations.

Here is a (compressed) video of Kit Golan enacting Connecting Representations with his 6th grade students.

We also created slides, a pre-planner, a lesson plan, and a description of the routine to go along with these videos.

A new project we are working on is to share the instructional components that make up the routines. Here is a video showing different talk moves that can be used by teachers, either within the routines or whenever they are needed.

Here is another video showing Kit that focuses on the annotation he did while another student restated the strategy of another student, showing that these different instructional strategies can be used together and towards specific instructional goals.

It is important that explanations in the math classroom are clear and complete so that all students can follow the mathematical arguments presented. Here is one of our teachers describing how she supported students in creating clear mathematical arguments for each other to follow.

Are videos like these helpful? Would more videos sharing some of these strategies be helpful (if so, which)? And can we share more math pedagogy with each other?

 

A friend of mine has been fostering a child that has been diagnosed with both autism and cerebral palsy. They have seen him grow from a child who could not talk and who had a great deal of difficulty using his body to a child who asks for help when he needs it, communicates his needs and interests with others, and who can climb up a climbing wall without difficulty.

My friend shared that they were quite shocked during recent parent-teacher interviews when they were shown her foster child’s “work” from the term. They were blissfully unaware during the first couple of months of school, during which their foster child enjoyed going to school and they believed he was also getting an education, that the he was in fact not being educated. Their biggest concern was that the work he did do, circling a few answers on 2 or 3 review worksheets each day, was not helping him progress. They wondered, what does he do all day?

Their position is that while it is true that this kid is behind, not giving him any productive work to do is not going to help him catch up. They are very worried that his needs are not being met, and I agree with them. I worry that his teacher is “meeting him where he is at” and that this means that he has little to no opportunities to grow. When this child has been supported and pushed to grow, he has responded by learning and growing immensely. The extremely low expectations that this child’s school has for him risk his future.

So what would you do if you were this foster parent?
