Latest / Rounding Up / Exploring the Seeds of Algebraic Thinking with Janet Walkoe & Margaret Walton
Transcript
- 0:03Algebraic thinking is defined as the ability to use symbols, variables,
- 0:08and mathematical operations to represent and solve problems.
- 0:12This type of reasoning is crucial for a range of disciplines. In this episode,
- 0:17we're talking with Janet Walko and Margaret Walton about the seeds of algebraic
- 0:21thinking found in our students' lived experiences and the ways we can draw on
- 0:26them to support student learning.
- 0:31Hello, Janet and Margaret. Thank you so much for joining us.
- 0:34I'm really excited to talk with you both about the seeds of algebraic thinking.
- 0:38Thanks for having us. We're excited to be here. Yeah, thanks so much.
- 0:42So for listeners without prayer knowledge,
- 0:44I'm wondering how you would describe the seeds of algebraic thinking.
- 0:48Okay. For a little context, more than a decade ago,
- 0:51my good friend and colleague, Mari Levine, she's at Western Michigan University.
- 0:55She and I used to talk about all of the algebraic thinking we saw our children
- 0:59doing when they were toddlers. This is maybe 10 or more years ago,
- 1:03in their play and just watching them act in the world.
- 1:05And we started keeping a list of these things we saw. And it grew and grew.
- 1:09And finally we decided to write about this in our 2020 FLM article that
- 1:14introduced the seeds of algebraic thinking idea. Since they were still toddlers,
- 1:18they weren't actually expressing full algebraic conceptions,
- 1:21but they were displaying bits of algebraic thinking that we called seeds.
- 1:27And so this idea, these small conceptual resources,
- 1:30grows out of the knowledge and pieces perspective on learning that came out of
- 1:34Berkeley in the 90s led by Andy Desesa.
- 1:37And generally that's the perspective that knowledge is made up of small
- 1:40cognitive bits rather than larger concepts.
- 1:43So if we're thinking of addition, rather than thinking of it as leveled,
- 1:48maybe at the first level there's knowing how to count and add two groups of
- 1:52numbers.
- 1:53And then maybe at another level we add two negative numbers and then at another
- 1:57level we could add positives and negatives.
- 1:59So that might be a stage based way of thinking about it. And instead,
- 2:03if we think about this in terms of little bits of resources that students bring,
- 2:07like the idea of combining bunches of things,
- 2:11the idea of like entities or non-like entities, opposites,
- 2:16positives negatives, the idea of opposites canceling,
- 2:19all those kinds of things and other such resources to think about addition.
- 2:23It's that perspective that we're going with.
- 2:25And it's not like we master one level and move on to the next.
- 2:28It's more that these pieces are here available to us.
- 2:31We come to a situation with these resources and call upon them and connect them
- 2:36as it comes up in the context.
- 2:39I think that feels really intuitive,
- 2:41particularly for anyone who's taught young children.
- 2:44That really brings me back to the days when I was teaching kindergartners and
- 2:47first graders. I want to ask you about something else.
- 2:50You all mentioned several things like this notion of do undo
- 2:55or closing in or the idea of in betweenness while we were
- 3:00preparing for this interview.
- 3:02And I'm wondering if you could describe what these things mean in some detail
- 3:06for our audience and then maybe connect them back with this notion of the seeds
- 3:10of algebraic thinking.
- 3:12Yeah, sure.
- 3:13So we would say that these are different seeds of algebraic thinking
- 3:18that kids might activate as they learn math and then also learn more formal
- 3:22algebra. So that first seed,
- 3:25the doing and undoing that you mentioned is really completing some sort of
- 3:29action or process and then reversing it.
- 3:32So an example might be when a toddler stacks blocks or
- 3:37cups.
- 3:38I have lots of nieces and nephews or friends' kids who I've seen do this often,
- 3:42all the time really, when they'll maybe make towers of blocks,
- 3:45stack them up one by one, and then sort of unstack them, right?
- 3:49So later this experience might apply to learning about functions,
- 3:54for example, as students plug in values as inputs,
- 3:58that's kind of the doing part,
- 3:59but also solve functions at certain outputs to find the input.
- 4:03So that's kind of one example there.
- 4:06And then you also talked about closing in and in betweenness,
- 4:10which might both be related to intervals.
- 4:13So closing in is a seed where it's sort of related to getting
- 4:18closer and closer to desired value.
- 4:21And then in former algebra and maybe math leading up to former algebra,
- 4:26the seed might be activated when students work with inequalities maybe or
- 4:31maybe ordering fractions.
- 4:33And then the last seed that you mentioned there in between this is the idea
- 4:38of being between two things. For example,
- 4:40kids might have experiences with the story of Goldilocks and the three bears and
- 4:45the porridge being too hot, too cold or just right.
- 4:49So that just right is in between.
- 4:51So these seats might relate to inequalities and kind of the idea that solutions
- 4:56of math problems might be a range of values and not just one.
- 5:01So part of what's so exciting about this conversation is that the seeds of
- 5:05algebraic thinking really can emerge from children's lived experience,
- 5:09meaning kids are coming with informal prior knowledge that we can access.
- 5:14And I'm wondering if you can describe some examples of children's play or
- 5:19even everyday tasks that cultivate these seeds of algebraic thinking.
- 5:25Yeah, that's great.
- 5:26So when I think back to the early days when we were thinking about these ideas,
- 5:30one example stands out in my head,
- 5:32I was going to the grocery store with my daughter who was about three at the
- 5:35time, and she just did not like the grocery store at all.
- 5:39And when we were in the car, I told her, "Oh, don't worry.
- 5:42We're just going in for a short bit of time,
- 5:44just a second." And she sat in the back and said, "Oh,
- 5:48like the capital letter A.
- 5:49" And I remember being blown away thinking about all that came together for her
- 5:53to think about that image, just the relationship between time and distance,
- 5:58the amount of time,
- 5:59highlighting the instantaneous nature of the time we'd actually be in the
- 6:04store, all kinds of things.
- 6:06And I think in terms of play examples, there are so many.
- 6:11When she was little, she was gifted a play doctor kit.
- 6:15So it was a plastic kit that had a stethoscope and a blood pressure monitor,
- 6:19all these old school tools, and she would play doctor with her stuffed animals.
- 6:24And she knew that any one of her stuffed animals could be the patient,
- 6:29but it probably wouldn't be a cup.
- 6:31So she had this idea that these could be candidates for patients
- 6:36and it was this, but only certain things.
- 6:39We refer to this concept as replacement,
- 6:43and it's this idea that you can replace whatever this blank
- 6:47box is with any number of things, but maybe those things are limited.
- 6:52And maybe that idea comes into play when thinking about variables in formal
- 6:56algebra.
- 6:58A couple other examples just from the seeds that you
- 7:03asked about in the previous question.
- 7:05One might be if you're talking about closing in games like when
- 7:10kids play things like you're getting warmer or you're getting colder when
- 7:13they're trying to find a hidden object,
- 7:16or you're closing in when tuning an instrument,
- 7:19maybe like a guitar or violin. And then for in between this,
- 7:24we talked about Goldilocks,
- 7:26but it could be something as simple as I'm sitting in between my two parents or
- 7:31measuring different heights and there's someone who's very tall and someone
- 7:34who's very short, but then there are a bunch of people who also fall in between.
- 7:38So those are some other examples.
- 7:41You're making me wonder about some of these ideas, these concepts,
- 7:46these habits of mind that these seeds grow into during children's elementary
- 7:51learning experiences. Can we talk about that a bit?
- 7:54Sure. Thank you for that question.
- 7:56So we think of seeds as a little more general.
- 8:00So rather than a particular seed growing into something or being destined for
- 8:04something,
- 8:05it's more that a seed becomes activated more in a particular context and
- 8:09connections with other seeds get strengthened. So for example,
- 8:13the idea of like or non-like terms with the
- 8:18positive and negative numbers,
- 8:20like and non-like or opposites can come up in so many different contexts and
- 8:24that's one seed that gets evoked when thinking potentially when thinking about
- 8:28addition. So rather than a seeds being planted and growing into things,
- 8:33it's more like there are these seeds,
- 8:34these resources that children collect as they act on the world and experience
- 8:38things. And in particular contexts,
- 8:42certain seeds are evoked and then connected. And then in other contexts,
- 8:47as the context becomes more familiar,
- 8:49maybe they're evoked more often and connected more strongly.
- 8:51And then that becomes something that's kind of connected with that
- 8:56context and that's how we see children learning as they become more expert in a
- 9:00particular context or situation.
- 9:03So in some ways it feels almost more like a neural network of sorts.
- 9:07The more that these connections are activated,
- 9:09the stronger the connection becomes.
- 9:12Is that a better analogy than this notion of like seeds growing?
- 9:16It's more so that there are connections that are made and deepened,
- 9:20for lack of a better way of saying it.
- 9:24And pruned in certain circumstances.
- 9:25And we actually struggled a bit with the name because we thought seeds might
- 9:28evoke this, "Here's a seed, it's this particular seed,
- 9:32it grows into this particular concept." But then we really struggled with other
- 9:36neurons of algebraic thinking news.
- 9:38So we tossed around some other potential ideas
- 9:42to kind of evoke that image a little better. But yes,
- 9:45that's exactly how I would think about it.
- 9:48I mean, just to digress a little bit,
- 9:49I think it's an interesting question for you all as you're trying to describe
- 9:53this relationship, because in some respects it does resemble seeds,
- 9:57meaning that the beginnings of this set of ideas are coming out of
- 10:03lived experiences that children have early in their lives,
- 10:08and then those things are connected and deepened, or as you said, pruned.
- 10:12So it kind of has features of like this notion of a seed,
- 10:17but it also has features of a network that is interconnected,
- 10:22which I suspect is probably why it's fairly hard to name that.
- 10:27And it does have ... So if you look at, for example, the replacement seed,
- 10:31my daughter playing doctor with her stuffed animals, the replacement seed there,
- 10:35but you can imagine that that seed, it's domain agnostic.
- 10:38So it can come out in grammar, for instance, the ad libs, a noun goes here,
- 10:43and so it can be any different now. It's the same idea, different context,
- 10:47and you can see the thread among contexts,
- 10:50even though it's not meaning the same thing or not used in the same way
- 10:53necessarily.
- 10:55It strikes me that understanding the seeds of algebraic thinking is really a
- 10:59powerful tool for educators. They could, for example,
- 11:02use it as a lens when they're planning instruction or interpreting student
- 11:06reasoning. Can you talk about this, Margaret and Janet?
- 11:10Yeah, sure, definitely.
- 11:11So we've seen that teachers who take a
- 11:16seeds lens can be really curious about where student ideas come from.
- 11:22So for example, when a student talks about a math solution,
- 11:26maybe instead of judging whether the answer is right or wrong,
- 11:30a teacher might actually be more curious about how the student came to that
- 11:34idea. So in some of our work,
- 11:36we've sort of seen teachers who have a SEEDS perspective can look for pieces of
- 11:41a student answer that are productive instead of taking an entire answer as right
- 11:45or wrong.
- 11:46So we kind of think that SEEDS can really help educators intentionally look for
- 11:51student assets and build off of them. And for us,
- 11:55that's students informal and lived experiences.
- 11:58And kind of going along with that,
- 12:00one of the things we really emphasize in our methods courses and is emphasize in
- 12:04teacher education in general is this idea of excavating for student ideas and
- 12:09looking at what's good about what the student says and reframing what a student
- 12:13says, not as a misconception,
- 12:14but reframing it as what's positive about this idea.
- 12:18And we think that having this mindset will help teachers do that.
- 12:22Just knowing that these are things students bring to the situation,
- 12:26these potentially productive resources they have, is it productive in this case?
- 12:31Maybe. If it's not, what could make it more productive?
- 12:34So having teachers look for these kinds of things we found is helpful in
- 12:38classrooms.
- 12:40I'm going to ask a question right now that I think is perhaps a little bit
- 12:43challenging,
- 12:44but I suspect it might be what people who are listening are wondering, which is,
- 12:49are there any generalizable instructional moves that might support formal
- 12:54or informal algebraic thinking that you'd like to see elementary teachers
- 12:59integrate into their classroom practice?
- 13:02Yeah. I mean,
- 13:03I think honestly it's listen carefully to kids' ideas
- 13:08with an open mind. So as you listen to what kids are saying,
- 13:12really thinking about why they're saying what they're saying,
- 13:16maybe where that thinking comes from and how you can leverage it in productive
- 13:20ways.
- 13:22So I want to go back to the analogy of seeds.
- 13:24And I also want to think about this knowing what you said earlier about the fact
- 13:28that some of the analogy about seeds coming early in a child's life
- 13:33or emerging from their lived experiences,
- 13:36that's an important part of thinking about it,
- 13:38but there's also this notion that time and experiences allow some connections to
- 13:42be made and to grow or to be pruned. What I'm thinking about is the gardener.
- 13:47The challenge in education is that the gardener who is working with students in
- 13:52the form of the teacher and they do some cultivation,
- 13:56they might not necessarily be able to kind of see the horizon,
- 14:01see where some of this is going, see what's happening.
- 14:05So if we have a gardener who's cultivating or drawing on some of the seeds of
- 14:10algebraic thinking in their early childhood students and their elementary
- 14:13students,
- 14:14what do you think the impact of trying to draw on the seeds or make those
- 14:18connections can be for children and students in the long run?
- 14:23I think a couple of important points there. And first,
- 14:27one is early on in a child's life,
- 14:29because experiences breed seeds or because seeds come out of
- 14:34experiences, the more experiences children can have, the better.
- 14:38So for example,
- 14:40if you're in early grades and you can read a book to a child,
- 14:44they can listen to it, but what else can they do?
- 14:47They could maybe play with toys and act it out.
- 14:49If there's an activity in the book,
- 14:51maybe they could pretend or really do the activity.
- 14:54Maybe it's baking something or maybe it's playing a game.
- 14:59And I think this is advocated in literature on play and early childhood
- 15:03experiences, including Montessori experiences,
- 15:06but the more and varied experiences children can have,
- 15:10the more seeds they'll gain in different experiences.
- 15:14And one thing a teacher can do early on and throughout is look at connections,
- 15:19look at, "Oh, we did this thing here.
- 15:20Where might it come out here?" If a teacher can identify an important seed,
- 15:25for instance, they can work to strengthen it in different contexts as well.
- 15:29So giving children experiences and then looking for ways to strengthen key
- 15:34ideas through experiences.
- 15:37One of the challenges of hosting a podcast is that we've got about 20 to 25
- 15:41minutes to discuss some really big ideas and some powerful practices.
- 15:46And this is one of those times where I really feel that.
- 15:50And I'm wondering if we have listeners who wanted to continue learning about the
- 15:55ways that they can cultivate the seeds of algebraic thinking,
- 15:58are there particular resources or bodies of research that you would recommend?
- 16:04So from our particular lab, we have a website and it's
- 16:09notice-lab.com,
- 16:12and that's continuing to be built out. The project is funded by NSF,
- 16:16and we're continuing to add resources. We have links to articles,
- 16:21we have links to ways teachers and parents can use seeds,
- 16:25we have links to professional development for teachers,
- 16:28and those will keep getting built out over time. Margaret,
- 16:31do you want to talk about the article?
- 16:33Sure. Yeah.
- 16:35Janet and I actually just had an article recently come out in mathematics
- 16:39teacher learning and teaching from NCTM,
- 16:42and it's issue five,
- 16:46and it's called Leveraging Early Algebraic Experiences.
- 16:49So that's definitely another place to check out. And Janet,
- 16:53anything else you want to mention?
- 16:56I think the website has a lot of resources as well.
- 16:58So I've read the article and I would encourage anyone to take a look at it.
- 17:02We'll add a link to the article and also a link to the website in the show notes
- 17:06for people who are listening who want to check those things out.
- 17:09I think this is probably a great place to stop,
- 17:11but I want to thank you both so much for joining us. Janet and Margaret,
- 17:14it's really been a pleasure talking with both of you.
- 17:16Thank you so much, Mike. It's been a pleasure. You too.
- 17:19Thanks so much for having us.
