Teaching with Problems at a Cafe

This is a story to support my belief when it comes to learning math. 

  1. I believe that students need to have basic math facts stored in long-term memory. 
  2. I believe students need to use these math facts to support logical arguments for mathematical conjectures.

I overheard two young girls (ending grades 4 and 2) practicing addition and multiplication facts in a cafe today. The older, Kate, asked her younger sister, Sara, "What is ten thousand plus one hundred?" to which Sara replied "Eleven thousand?"

Kate: No.
Sara: Eleven hundred?... eleven...
Kate: No, ten thousand one hundred.

Kate: How about 23 times 18?
Sara: uuummm, thirty- no forty one.
Kate: Times! silly
Sara: oh, hmm...

I felt compelled to save Sara from questions that were a bit beyond her apprehension, while challenging Kate with something more than just declarative knowledge. Since their mother was present, it might be an opportunity to model effective differentiation of a problem space to involve both of her children. I happened to be reading a book on "Teaching with Problems" and wondered how they would fare with one of Lampert's problems of the day. The focus of Lampert's teaching is to have students "reason from assumptions to their implied conclusions". I knew I could ask a question involving 2-digit addition and subtraction (a skill they both could perform), that would still be challenging for Kate to figure out.

I wrote the same question on two sheets of paper and gave the girls pencils to experiment with.
I. Problem of the day
I expected the girls only to attempt part a of the problem, but I included part b because I was curious how someone would go about using hundreds with such a problem format. This is something Lampert alludes to in her book but doesn't go into detail on. The girls did not end up making their own assumptions about what could fit in the boxes, but operated under an assumption that single positive digits would occupy each box.

The girls started by finding one correct subtraction problem, each declaring: "I found one!"

I asked them to share what they found,
Kate: 46 - 23 = 23
Sara: 33 - 10 = 23

At this point a friend of Sara's named Jane (also ending grade 2) joined her in solving the problem. I explained to their mother that the girls were now practicing their subtraction facts without being asked to do a worksheet, because they were necessary experiments to find a pattern that would lead to conjectures to count all of the subtraction pairs they could find.

Both solution paths started as lists of all subtraction pairs involving tens {33-10, 43-20, ... 93-70}:
II. Kate's initial experiments
III. Sara & Jane's initial experiments
The girls were satisfied that they had found multiple solutions to the problem, but I reminded them that the question wasn't to solve the subtraction problems, but to figure out how many there were. I also wondered if we could make an estimate of how many there were, without listing them all. As the girls began to lose interest in the problem, I realized they would need more guidance to come up with estimates. Kate's mother encouraged her children by saying, "I am curious to know how many there are! Aren't you curious?"

I pointed out to Kate that some of her solutions had too many digits, and she crossed out 103-80 and 113-90. She drew a bold line to indicate the maximum for subtracting by tens. I asked her if she had found all of the subtractions ending with the digit 0 and she said, "yes", although at this point she had not considered 23-00 (top left of fig IV. added to fig II).

I guided her with a plan that might help us come up with an estimate. If we had found all of the subtractions ending with the digit 0, could we do that for all of the ending digits? For example, I pointed out that she had found one subtraction ending with the digit 3, her first attempt which was 46-23 = 23. This spurred her on to find all subtractions ending with the digit 3.
IV. Kate's further experiments
With further guidance from me and her mother, Kate came to an initial estimate of 80 combinations. She had discovered 26-03 and realized 23-00 would also work, so she was making a conjecture that there were 8 possible combinations for each digit, and 10 total digits. I left Kate to work with her mother on the final details of her approach and checked on Sara & Jane.

I asked, "How many combinations do you think there are?", and Sara replied "We found 14!"
V. Sara & Jane's further experiments
Given the level of support Kate needed to make an estimate of 80 using the final digit approach and her higher level of mathematical ability, I was glad that there was the beginning of a different pattern on this paper. Namely, {23-0, 24-1, ... 29-6}. I pointed out that we could continue with this pattern, but when we repeated 33-10, Sara noticed and was like "uh oh! we already are counting this one!"
VI. Sara & Jane's new pattern
I started listing all of the subtractions in order without writing them to suggest that we would repeat all of the subtractions by ten she had listed earlier with this new pattern. I wondered out loud when this pattern would end and I asked, "what is the biggest 2 digit number that we can subtract from?" and Sara replied "99". I told her to leave space for all of the other pairs, so she wrote it very small in the bottom corner.

After all of this, I had lost Sara a bit and she was still guessing her estimate: "88?" I could see that having two different approaches on the same list was interfering with her ability to see the new pattern I was trying to extend. But she continued thinking about the problem, and before I left the shop she suggested to me, "My estimate is 76, because there will be 76 subtractions." I noted that she wasn't counting 23-0, and she revised her thinking and said "77!"

VIII. Sara & Jane's response
VII. Kate's response
Overall, I feel like I did too much leading in this exercise, and it uncovers some of the pitfalls that a teacher will encounter using open-ended problems. However, given the time constraint of meeting in a cafe, and the design constraint of not knowing the girls' prior knowledge; I was pleased that both girls had come to believe in their guesses, had consensus in their results, and had used different approaches.

More importantly, the discourse between the sisters shifted from Kate demonstrating her prowess in mathematics by asking her sister declarative questions that were beyond Sara's level of understanding, to an exploration in which both girls were engaged in productive struggle. There is no clear "winner" in a situation where two girls come to the same answer through different solution paths, both require help, and both make small contributions throughout the exploration.

We need to equip our students with a strong foundation of math facts, but let us not forget to ask questions that require them to use this knowledge to produce new knowledge.

I recently read Magdalene Lampert's excellent analysis of teaching in, Teaching Problems and the Problems of Teaching. Without which this experience would not exist, so thanks for that effort.

Constructive Negative Feedback


I read a NYT article today by Natasha Singer about ClassDojo (CD) and was unnerved. How many classrooms did the author visit that gave her the authority to write this piece? I have observed CD being used in a handful of classrooms, so I would never claim myself to have enough authority to write for such a large audience as the NYT on the topic, but the dissonance between my experience of CD and the claims in this article were enough to prompt a comment. I don't subscribe to NYT, and after reading this article probably never will, so I am pasting my comment as a blogpost and sending links to Natasha. I hope that she can provide more evidence in support of her argument so that I can continue to have respect. In an effort to make this rant educative, I am using this to illustrate my thoughts about constructive negative feedback. Please give me some! Thanks.

Dear Natasha,

It is unsurprising that you are fearful of teachers abusing the power of ClassDojo by doling out unwarranted negative feedback to their students. This article is an example of the behavior you so fear. I am a huge supporter of negative feedback, when used responsibly.

Responsible feedback states a goal and a consequence, assesses performance, and issues the consequence. Here’s an example: Natasha Singer, I expect all articles I read to make claims that are supported with sufficient evidence, otherwise they aren’t worth reading (Goal and Consequence). I don’t believe that all of the points made in this article are backed up with sufficient evidence (Assessment). Therefore, I will no longer read articles by you, and am less likely to read Times’ technology articles because this was a poorly researched piece (Issue consequence).

For a second example, I will use one of yours, “ ‘I’m going to have to take a point for no math homework’, Mr. Fletcher said...” This is constructive negative feedback as long as Mr. Fletcher has stated his expectations and consequences in a structured policy for his students. There is a clearly stated goal, the student did not achieve it, and there is a consequence for not achieving it.

You have properly identified some solid goals for ClassDojo, (1) Keep student data secure (2) Don’t sell student data (3) Don’t reward negative behaviors (stigmatize children). However, you did not provide solid evidence to support the claim that ClassDojo does not achieve these goals. Sam, Liam and the ClassDojo team did a much better job defending their efforts to achieve these goals. Yet, you still acted in a position of authority and issued a consequence in the form of a negatively slanted article of their product.

Every mistake is an opportunity for growth. The fact that the ClassDojo team could so quickly refute your points means that in the future it would serve you to ask more targeted questions in order to shore up your argument (this is advice, not feedback). If there is further evidence to support some of your claims I would love to hear it, because I also fear that teachers may end up dishing out unwarranted punishments.

Thank you for the article and highlighting very important goals that all education companies, teachers, and parents should be concerned with.

For a much better article on feedback than mine, read Grant Wiggins' piece on the topic: http://www.ascd.org/publications/educational-leadership/sept12/vol70/num01/Seven-Keys-to-Effective-Feedback.aspx

Full disclosure: I trust teachers. I taught for 8 years and work in instructional design. ClassDojo’s success does not directly impact me. However, they are a company that trusts teachers. I support organizations that trust teachers. When organizations that trust teachers get a negative image, it usually supports the predominant culture that permeates our less informed public.

Resources To Accelerate High Algebra Achievement



I ran into an LDT alumnus named Dan Gilbert on Saturday who helped facilitate Stanford's GSE Energizer, and he asked me a great question, 

'My son is high achieving in algebra, what resources do you recommend for him?'

Depending on the learner, there are a plethora of options out there. So a more specific request or richer context might produce better resources. However, I will do my best here to answer the general question,
What resources are available for a high algebra achiever to accelerate their growth in understanding?

This is relevant to parents and educators alike. This is a draft list, and I would love your feedback on it as well as additions you might suggest in the comments.


1. POW (Problems of the Day/Week/Month #Problemoftheweek)



GOOD for motivated learners who want a challenge.
BAD for reluctant learners who would rather do something else.

I really liked the NCTM Calendar problems when I was ~7th grade. Unfortunately, they require NCTM membership to access. I also think that my math club in high school, involvement in tournaments, and acadeca helped to support my mathematical development. Below I list two of the current social options to support learning (Communities and Competitions) as well as two newer supports (Practice Engines and Games).



2. Communities (Clubs, Makerspaces, MOOCs, social media...)             


GOOD for social learners whose experience a supportive environment.
BAD when the learner and community have different goals or there is insufficient support.


Find communities
    School clubs (Academic decathlon, math, robotics,
    cryptography...)
    Hacker spaces
    Makerspaces
    Afterschool programs
    Reddit, youtube or other forums

    Cyber Patriots - https://www.uscyberpatriot.org/
    MESA - http://mesa.ucop.edu/




3. Competitions (AMC, Mathcounts, University competitions...)


GOOD for motivated and competitive learners who want to push their limits.
BAD for social learners who dislike competition or underachievers who need more support.


I participated in the AHSME and a few local university competitions while in high school and enjoyed being part of a team in many of the school competitions. The next categories are things I wish existed when I was a kid, and areas where innovation is creating opportunity.



4. Practice Engines (Khan, IXL, Alcumus...)


GOOD for tracking and individualization of procedural skill practice.
BAD for conceptual understanding and higher order thinking skills.




Find Practice engines

Free Common Core Curricula

The CCSS are a set of desired results, not a curriculum. However, we still need strong curricular materials if we are to deliver instruction that will allow our students to exceed the standards.

I have been pleasantly surprised by the material developed in


Exploratory introduction to new concepts from eNY

and Utah, http://www.mathematicsvisionproject.org/

Practice Understanding Task from MVP, which follows teaching and learning cycles

Are there some I have missed? Where are the other states at?

Enjoy work,

The Chocolate Head Space Promotes Recognition of “Human Ingenuity” through “Play and Work”

The instruction of Aleta Hayes and the Chocolate Heads Movement Band (Chocolate Heads) increased my confidence to learn. This community encourages public exclamations of recognition, or what Erving Goffman refers to as “Response Cries”.

Just as most public arrangements oblige and induce us to be silent, and many other arrangements to talk, so a third set allows and obliges us momentarily to open up our thoughts and feelings and ourselves, through sound, to whoever is present. Response cries, do not mark a flooding of emotion outward, but a flooding of relevance in.
- Erving Goffman, “Response Cries.”(1978, p. 814) [Formatting added]

I sit in the Graduate Community Center laughing out loud while reading, “chuckling aloud to ourselves in response to what we are reading is suspect; this can imply that we are too freely immersed in the printed scene to retain dissociated concern for the scene in which our reading occurs.” (Goffman p. 791) I make more “exclamatory interjections” (Goffman p. 800) since becoming a Chocolate Head and I feel less obliged to be silent because expressive outbursts are encouraged and appreciated among us. I approach life with more of a willingness to learn and celebrate my mistakes in hopes of inspiring others to join us. Aleta Hayes builds a company in which every artist (dancer, musician, lyricist, technologist, director…) plays a part in the overall construction of the piece. The style of collaboration used to choreograph our movement is daringly complex, and wonderfully simple. It cultivates confidence, learning to learn, and creative construction in a superior manner than I have encountered in traditional learning environments.
Ray McDermott and Jason Raley made the claim that, “the social world is built by people working together, and by their work we can know them.” (2011, p. 388) and John Dewey warns that, “It is not enough just to introduce plays and games, hand work and manual exercises. Everything depends upon the way in which they are employed.” (1916, p. 3) There are myriad activities that Aleta Hayes has our group perform, and this analysis is an attempt to connect my learning in the Chocolate Heads Space to Dewey’s ideas around “Play and Work in the Curriculum” (1916) and McDermott & Raley’s insights around “Human Ingenuity” (2011). In their piece entitled, “Looking Closely: Toward a Natural History of Human Ingenuity”, McDermott & Raley explain, “To fashion a natural history approach, we state a problem, make a claim, and promise a better way to proceed.” (p. 374)

Problem Statement
Often when teams are working together, there is a lack of trust needed to have effective collaborative interaction. It is easy to doubt oneself or others. It is difficult to allow oneself to be vulnerable. Teacher-student interactions are a prime example of work between collaborators who need to develop trust. McDermott and Raley describe the current extent of that relationship (p. 381):
From the child’s point of view, the day is spent arranging to not get caught not knowing something and/or getting caught knowing something at just the right time. From the teacher’s point of view, the day is spent finding failure while, at the same time, preaching the availability of success for all and trying not to degrade those who look less able.”
As far as ingenuity is concerned, McDermott and Raley assert that “official school environments either make ingenuity appear scarce, make ingenuity a refugee phenomenon, or bend the purposes of ingenuity toward the pursuit of being seen being able.” (p. 387) How might we increase the level of professional trust between collaborators, and will they perform with more human ingenuity once it is raised?

Claim
People want to build trust and be a source of ingenuity. People enjoy spending time with their friends, family, and acquaintances because it is more comfortable to be around others with whom we share reciprocal trust. We often behave more playfully in trusting settings. “Persons who play are not just doing something (pure physical movement); they are trying to do or effect something“ (Dewey, p. 10). Work and play are not disjoint.
When fairly remote results of a definite character are foreseen and enlist persistent effort for their accomplishment, play passes into work. Like play, it signifies purposeful activity and differs not in that activity is subordinated to an external result, but in the fact that a longer course of activity is occasioned by the idea of a result.  (Dewey, pp. 11-12)

Promise
There are better ways to develop trusting relationships in learning environments. Great teachers organize events to scrutinize people’s activities and gain what McDermott & Raley describe as ability to, “see accomplishments, critiques, and frustrations where others have seen only disorder and stupidity.” (p.375) Aleta Hayes and the Chocolate Heads incorporate methods that approach this promise and arrange events to promote human ingenuity. “Given the materials and persons and moments at hand, what a person does is ‘ingenious’ if it transforms those materials into something interesting, fun, or new.” (McDermott & Raley, p. 387)

Observation
Collaboration plays a pivotal role for dancers. If each individual movement doesn’t synch with the whole group, the effect can be emotionally discordant. However, when the movements are harmonious, the resulting expression becomes sublime. There is a lot of pressure on choreographers because dancers need rehearsal time to perfect a performance. This time constraint causes many choreographers to develop whole pieces before working with the dancers, and leaves little time to make adjustments based on the dancers’ abilities. However, that culture divides “dancers” and “choreographers”. This division makes the role of the dancer mimicry and memorization. Subsequently, most dancers aren’t allowed the freedom to contribute to or alter the performance.
The notion that a pupil operating with such material will somehow absorb the intelligence that went originally to its shaping is fallacious. Only by starting with crude material and subjecting it to purposeful handling will he gain the intelligence embodied in finished material. (Dewey p. 5)
Aleta agrees. The resulting choreography, music, and visual design of the Chocolate Heads Movement Band become an amalgam of the “crude material” that each individual’s particular talents helps mold. They develop individual parts that change with time. They mix and combine different elements from each artist's part to build whole movements. There is an overarching structure of a story, but it is loosely constructed and freely changes day to day. Aleta emphasizes the feeling of a movement over the idea of a narrative. Dancers practice and iterate on their choreography while the instructor circulates the floor and critiques each routine. Aleta recognizes what looks good; and when she sees it, she has dancers teach each other the appropriate way to perform a movement. It constantly develops through this “purposeful handling” as an artistic production being orchestrated by a great teacher. It begs the question, what is the underlying mechanism that allows Aleta to create such a creative culture among artists who have often just met?
Of course there are numerous confounds: Stanford students are motivated, artists and dancers self-identify as creative, the Bay Area is full of unrealistic optimism and positivity, but there is something different about the Chocolate Heads even when compared to other dance groups on Stanford’s campus.
Fig. 1
Chocolate Heads have a culture of connectedness.
On my second night dancing with the Chocolate Heads (and for many of them, it was anywhere from their 10-20th rehearsal), I found it interesting that when Aleta came to help this pair of dancers (Fig. 1), she noted that they were not doing as well in her presence than when she was glancing at them from across the floor. It was a very astute observation and an example of the inviting, honest, and loving way that Aleta nurtures a relationship with us. My interpretation of this was that the connection between the students was stronger than their connection to the instructor at that time. She was building trust, and after making the imbalance explicit, the dancers embraced the confidence she instilled in them. Aleta then arranged the whole group to focus on our connectedness. For inspiration, we watched a clip with professional dancers who were so connected that they moved as if they were "one body". Imagine a group of twelve dancers making uninhibited “response cries” when the relevance of connected movement hits them all at once. To help foster this among us, she had everyone move in sync through different activities: traversing the floor in groups of four with the “same foot-fall”, having each member create a movement and asking each group of four to “copy dancer ____” while maintaining the “same foot-fall”. Near the end of our rehearsal session, and in the beginning of subsequent sessions, we perform synchronous movements to get in-tune with each other’s body. We make "waves", create “seas”, and develop trust for each other.
This process is an ongoing acculturation. I produce movement with this group part-time, and started this school year late (in winter quarter). Nonetheless, I have been embraced by the group’s loving energy, and feel myself growing both as a dancer and team member. My continued involvement has exposed me to some of the ways that Aleta pushes each individual dancer to pull the desired expression out of themselves, and the qualities that make her an excellent teacher:
·    Public Recognition with Repetition: “Whoa! Look how ____ did it! Do it again, everyone watch.”
·         Fostering Creativity with our Bodies: “What else can you do? No… what else? YES!”
·      Attention to Detail, Noticing Bad Habits and Targeting Mismovements: (“Stay in your heels”, “sexy is an inside job”, “from the outside in”, “from the inside out”, “five-pointed star”, “out your toes”, “out your hands”, “flex your feet”, “point your toes”, “get up like a dancer”, “be the master of all that you survey”, “honey hands”…) 
These are important points, because it is Aleta’s expertise and ability to transform us as dancers that solidifies our trust in her and each other. She demonstrates these qualities as a teacher and successfully leads a group of artists to organically synthesize an endless array of new ideas. Her orchestration is an act of ingenuity, and as a result of it, she enables her students to behave ingeniously in turn.

Let’s Assess Better


A critique by Evan Rushton of
Looking Closely: Toward a Natural History of Human Ingenuity
by Ray McDermott and Jason Raley

Ray and Jason, you had me at “We agree.” (p. 1)

“…people are usually ingenious, both locally in their most personal circumstances and collectively in their most distributed consequences. In coordinating with each other, people show themselves, to those who would look carefully, to be orderly, knowledgeable, and precise. Given the demands of necessity, they do well what has to be done even if under limiting, or worse, pathological conditions.” (p 1)

I agree in the contrapositive of the final statement regarding a lack of ingenuity among spoiled children: “They do poorly what has to be done, without the demands of necessity.”  I say this because I see people performing poorly (wasteful, inconsiderate, uncreative…), and draw the conclusion that we are not demanding these values (conservation, consideration, creativity…) from them. This is an argument against predominant forms of assessment, and a call to “look closely” at how we can support the development of skills our students need in the 21st century.

We demand something from our children, and I agree that “[g]iven the demands of necessity, they do well what has to be done…” perhaps too well. Using mathematics as an example, students in 8th grade honors geometry (“High Achievers”) who took Silicon Valley Mathematics Initiative’s Mathematics Assessment Collaborative’s (MAC) performance assessment exam in 2012 performed well on standardized multiple choice tests (96.1% CST at or above Proficient), but poorly on free response questions (45.6% MAC above proficient) http://youtu.be/MOSS04seBF8?t=57s. In 2nd grade, 76% of the students were scoring above proficient in both the MAC and CST exams, but over time students were trained to perform well on the only measured outcome, the multiple choice questions.  So much so that by 8th grade, only 45.6% of our high achievers perform proficiently on critical thinking tasks.

We attempt to condense the learned experiences of children onto a ballot used to measure student growth. I see a parallel between standardized tests and the way Ray and Jason speak of 20th century social sciences’ objectivity, “Even personal developments and events − even desire − get described and managed as if intelligible to a cold and calculating eye that looks on activities not as they are performed, but by their symptoms − their droppings − lined up in patterns only after they have run their course.”  (p. 2) And I believe that we can do a better job, with assessment that gets at what William James recommended in 1897, “’a more radical empiricism’ that seeks things in the full variety of their connections in experience” (p. 3)

When I drive alone, I usually make good lane change and turn decisions. But I always warn my passengers, that when other people are in the car I rely on the shared knowledge to direct us to our location. This often leads to missed streets and U-turns. I can’t control the huge shift in my personality between an empty vehicle and the “ones-with-others” vessel. But I know the latter is more difficult to manage, and is closer to the stuff of human interaction. The authors claim, “[A] natural history analysis examines organisms and environments interwoven in real time in situations consequential to their participants and beyond.”  (p 2) Ray and Jason’s goal in using a natural history approach is also what I see as the window through which we can accurately measure learning: “[I]t is ‘not the point of view of one toward the other’ that we seek, but ‘the very processing itself of the ones-with-others.’” (p 3)

How do we assess that?

Googling "rails video tutorials" aka Learning Rails

I took CS 106A at Stanford, and "Mehran Sahami change my life!" as I'm sure he has done for many Stanford-crafted software developers.

So I have decided to learn enough Ruby on Rails to finish a rubric-based assessment tool that a friend was building. I will reflect here and will be updating this post regularly.

I tried on my own* - to little avail. So I took CS 142 Web Development at Stanford, and learned that higher level CS courses at Stanford have a DIY feel. A bit tricky when you are a grad student with few friends in the class. So I became an office hours inhabitant and made some friends, the TAs were accessible and made the class very manageable.

<!-- To be continued -->







*Preliminary Musings
I'll be starting with some reading of http://ruby.railstutorial.org/ruby-on-rails-tutorial-book

http://railsforzombies.org/ has been fun.
http://tryruby.org/ was a bit glitchy... but taught some syntactical rules.

I wanted to check the usual MOOC suspects and iTunesU for a short listing, but figured someone's blog contains this search. So I gBlog-searched, "best ways to learn ruby on rails"

I then read:

http://blog.appfog.com/quite-possibly-the-best-rails-tutorial-in-existence/

http://astonj.com/tech/best-way-to-learn-ruby-rails/

http://www.readysetrails.com/index.php/1951/the-very-best-way-to-learn-ruby-on-rails/

suggested codeschool

Started to watch nettuts+

Talked to a web-developer who wrote the code I am attempting to add to, she said:

1) Google MVC framework - first chapter or two of book or something similar (conceptual)
understand js, html, css. Make sure its Rails 3.2 and ruby 1.9

2) Think of an action that a user can perform. And can you trace it through the code?

3) Get everything working from my machine. Installing ruby, installing rails, requisite gems,

Once comfortable use (rails s) to localhost and test changes to the code.

I might use free video tutorials at  ShowMeDo

There are responses in a forum thread on stackoverflow and that led to stackoverflow's learning threads

Pretty sure I can youtube it for free.
