Sidebar: Learning about learning – a conversation with Deborah Tatar

Dr. Deborah Tatar, Virginia Tech
Deborah Tatar, cognitive scientist at Virginia Tech

Deborah Tatar is a cognitive scientist at Virginia Polytechnic University whose current research focuses on understanding and clearing the obstacles to student learning in mathematics and science. For example, she was a principal investigator on the SimCalc project, a software-based interactive math curriculum for middle schoolers that has shown demonstrable success when accompanied by professional development for teachers. She is a collaborator on the CPATH Distributed Expertise project for which I am a co-PI.

In this conversation about what it takes to bring students from under-represented groups into computing, Tatar cautions against easy generalizations and simplistic solutions, offering intriguing possibilities for ways in which we can assist learners in finding the paths to understanding that are most appropriate for them.

Tatar’s insights remind me of Georgetown University math professor Jim Sandefur’s use of “think-alouds” – recorded interviews with students who explain their thought processes while working on math problems. It also echoes and complements the insights from Visible Knowledge Project, spearheaded by Randy Bass during the last decade. I was a researcher in that project in the early 2000s. My research project for VKP, “Blogging on the Beat” details my action research project on whether having journalism students keep blogs will lead deeper and more richly-sourced reporting.

This interview is part of my work in progress: The Re-Education of Me: Journalism, Diversity and Computing. Pearson, a long-time professional writing practitioner and educator, is using auto-ethnography and literary journalism to probe the implications of the transformation of journalism by computer science for journalism education. This interview was recorded at the National Science Foundation’s CE 21 community meeting in New Orleans, Lousiana Jan. 30, 2011.

“There are, at least, two approaches to education: the mimetic approach and the mathetic approach. The mimetic approach emphasizes memorization and drill exercises and is most efficient in inculcating facts and developing basic skills [Gar89, p. 6]. The mathetic approach stresses learning by doing and self exploration; it encourages independent and creative thinking [Pap80, p. 120]. In the mimetic framework, creativity comes after the mastery of basic skills. On the other hand, proponents of the mathetic school believe that self discovery is the best, if not the only, way to learn…”

Educational Outlook,”

Sugih Jamin, Associate Professor, EECS, University of Michigan

“Music educators can no longer ignore the possibilities afforded by computers and the related fields of science and mathematics.” With those words, Virginia Hagemann threw down the gauntlet to her colleagues in a 1968 essay for the Music Education Journal. It was the first of two articles she would write about the electronic music laboratory that she created at the JR Masterman Laboratory and Demonstration School in Philadelphia in the late 1960s.

I was a participant in that lab, and as I read Ms. Hagemann’s essays, I was struck by the parallels between her arguments for the effectiveness of electronic music and a tool for expanding the horizons of secondary school students, and the research and findings from the Interactive Journalism Institute for Middle Schoolers, a National Science Foundation-funded project for which I served as a co-principal investigator. Like Ms. Hagemann, we found that given the opportunity to make media, young people can produce artifacts that reflect fairly sophisticated concepts. We also concluded that professional development that empowers teachers is central to successful curricular innovation. Ms. Hagemann also learned serendipitously that a budding media maker is capable of becoming a technology innovator.

In this essay, I want to place Hagemaan’s action research alongside the work of Seymour Papert and his intellectual descendants to turn computers into learning tools for children. While Hagemann was developing her ideas about electronics as a vehicle for musical composition and education, Papert and his colleagues at MIT were creating the LOGO programming language as a tool to help children construct their own knowledge about the world. With this foundation, he reasoned that teachers could then support students in moving to more formal understandings of concepts in mathematics, physics and other subjects that are generally considered abstract and difficult to learn.

Research shows that music education can be a wonderful foundation for teaching mathematics and by extension, computing.(Research on music and learning) The reasons are not hard to understand: both require that information be organized in certain structures. Pattern recognition is integral to both fields. Both have formal and informal “languages.” One can draw analogies between their elements – bits and bytes of computing and the diatonic scale in Western music, for example. Music has its own versions of computing’s “if-then” statements, loops, strings, recursion, modularization and other fundamentals. Both are fundamentally mathematical, although not necessarily in a “school math” kind of way. Looking back, I can see how many of these concepts were embedded in the work we did in Ms. Hagemann’s electronic music class.

For the sake of context, I should mention that I also had traditional classes in basic music appreciation and theory while at Masterman, taught by Gloria Goode.   Ms. Goode also expanded our cultural horizons. She added jazz, African and Brazilian music to our studies of Dvorak, Copeland and Stephen Foster. In sixth grade, we happened to have a student teacher who had lived in Brazil, so we learned to make their national dish, fejoida, home ec class and performed a Brazilian number in the school show. As one of the few black faculty members at Masterman, she was a powerful role model for the black students. She was also a crucial mentor for a small group of students who actually did become professional musicians in their adult lives. She also set an example for us as a life-long learner, sharing with us about her explorations of African music and dance, for example. Her 1990 doctoral dissertation, “Preachers of the word and singers of the Gospel: The ministry of women among nineteenth century African-Americans,” was hailed by the author Delores Causion Carpenter hailed as, “one of the finest treatments of 19th century black, singing, evangelist women” in her book, A Time for Honor: A Portrait of African American Clergywomen.

The exposure that she gave us to polyrhythms through the music of Babatunde Olatunji has particularly stayed with me. What follows is a video collection of the some of the music I was exposed to in Ms. Goode’s classes. I believe that what she taught me about the underlying structure of these diverse kinds of music would become important in Ms. Hagemann’s class, and in my later thinking about writing and problem solving. This collection includes not only Olatunji, but also Sergio Mendes, “Largo” from Dvorak’s New World Symphony, the folk song, “Goober Peas,” Della Reese and Wes Montgomery playing “Windy.” The last song especially sticks out in my mind because my first hearing of the song wasn’t Montgomery’s guitar version. It was our fifth-grade classmate Joel Bryant, who played the song for us on piano at her invitation at the end of class one day. Joel went on to become an accomplished professional songwriter, producer and accompanist with credits that include work with Philadelphia International Records and Gospel great Traimaine Hawkins. Joel was one of many professional musicians who came through Masterman.

Ms. Hagemann’s essays don’t explain what specifically prompted her to create an electronic music class, but she knew Robert Moog, the physicist-engineer whose experiments with the theremin led to his invention of the first popularly-used synthesizer in 1965.  She was an active composer with far-flung connections who reportedly studied with the legendary music teacher Nadia Boulanger. (This assertion comes from a posting on Facebook; I am in the process of trying to verify it.)

What we do know from her 1968 essay, “Electronic Composition in the Junior High School,” is that she described the lab as “logical outgrowth and extension of the [Music Educators National Conference] Young Composers’ Project,” an initiative funded by the Ford Foundation. She started the lab with a $316 grant from a fund established by Philadelphia Schools Superintendent Mark Shedd for innovative teaching projects. According to Salon magazine, Moog synthesizers were $11,000 in those days, so she focused on components instead. We had two reel-to-reel tape recorders, an oscilloscope, sine and square wave generators, splicing equipment, and tools for making musique concrete, such as a gong and a metronome. We wrote our compositions on graph paper, plotting frequencies on the vertical axis and time on the horizontal.

According to Hagemann, the 15 children were initially selected to participate in the lab, and several dozen students were admitted into the program before long because of popular demand. All of the students who were initially selected played instruments. If my memory is correct, I entered the program during the 1968-69 school year, when I was in the sixth grade.

Ms. Hagemann’s methods emphasized the mathetic over the pedagogic or mimetic. Each of us was assigned a partner,  which meant that we not only had the experience of composing and recording our own work, we also learned to play recording engineer for someone else. She exposed us to experimental composers and methods, and further broadened our cultural horizons. The video compilation below is a sampling of what we heard in class, and what we were taught to do. It includes Switched on Bach, Tibetan chants, a demonstration of musigue concrete composition and production techniques, and a Swingle Singers performance.

This early electronic music composition, “Lemon Drops,” by Kenneth Gaburo, was also part of our curriculum:

Hagemann cautioned her colleagues against being “guided by an outmoded philosophy that only the teacher knows best.” At the same time, she added,

“Although anything is possible, everything should not be permitted. In this incipient stage of a student’s musical development, the disciplined experi- ence of creating logical compositions within the frame- work of accepted musical form is imperative. Although students should become aware of the concept of alea- toric composition (eleven of the twenty-six members in the first class purchased John Cage’s book, Silence), the use of indeterminacy and chance elements in com- position should be reserved until the students have demonstrated their understanding of and competence to compose in various musical forms. Concurrent with a rigid adherence to traditional form, the children can be given a measure of freedom of expression to avoid stifling the possible creation and development of new musical structures.” (p. 88)

Hagemman reported surprise and delight at the quality and precocity of the musical compositions that emerged from the class (not from any of my work , though, I assure you!). But it was the technological innovation that took place that was an additional delight. She reports on page 90 that after field trips to Princeton and Philadelphia’s Franklin Institute:

“William Serad, age thirteen, submitted a technical report, complete with schematic diagrams, on the possibility of using an analog computer for writing electronic music. William thought that this computer would be useful in the writing of such compositions as “Study in Square Roots” or “Cube Root Canon.” His report was later discussed with Robert A. Moog, presi- dent of the R. A. Moog Company, Trumansburg, New York, manufacturers of electronic equipment, who agreed that this idea was feasible. With this encourage- ment, William constructed a four-sound, push-button switch, serial sequencer, which he used in writing an electronic canon. He has since made a working model of a tri-amplitude mixer module. Another member of the class, Randy Kaplan, age twelve, was inspired by the linear controller at Princeton to build a three- sound, push-button switch, serial sequencer with mixer. The teacher will not always understand every wire and transistor, but he can always tell if the equipment operates properly, and he can assist his students to use such devices musically.”

Hagemann concluded her article by noting that keeping up with her students had required her to embark on a new path of professional development for herself. She enrolled in an electronics course and started reading electronics reference texts.  She picked up the theme of the necessity of teacher development in a Dec. 1969 article for the Music Education Journal, “Are Junior High School Students Ready for Electronic Music? Are Their Teachers?”  Hagemann asserted that if teachers open their minds and become resourceful about using electronic music classes as a means of allowing students the “freedom to create” (.p 36) ,

“The adolescent need for independence will be satisfied by the creative free- dom encouraged within the labora- tory. The study of the basic con- cepts of electronic music will help the student gain a critical perspec- tive of himself, of his social environ- ment, and of the ways he can shape new goals of learning.” (p.37)

I was astounded to read these words nearly 40 years later, because they are remarkably similar to the conclusions that we reached with regard to the results of our Interactive Journalism Institute for Middle Schoolers in exposing middle school students and teachers to computing and journalism as as means of creative expression and civic engagement.  More about that in a future post.

From the NSF CE21 community meeting: Meet Lily Fae Pierre

I spent the last several days in New Orleans with 400 computer science educators, education researchers and policy makers at the National Science Foundation’s CE 21 community meeting. CE 21 is a new initiative to boost K-16 computer science education. Central to that effort is a commitment to strengthen computer science curricula and teaching at the high school level.

One of the most interesting people I met there was Lily Fae Pierre, a computer science teacher at Los Angeles High School. A former industrial engineer who became interested in technology as a resul of growing up on a family farm in Mississippi, Pierre uses chants and cheers to educate and engage her students. She allowed me to record one of her routines:

One late afternoon in April, 1967, the guidance counselor at Kearny had called me and my parents in to tell me that the transfer had been approved. I could throw away my homework for that day; I was going to my new school tomorrow. This wasn’t unusual, I would learn later. After months and years on waiting lists, the word that we’d been admitted to Masterman often came suddenly, at odd times during the school year.

The next morning, I was led into Mr. Cragg’s fourth-grade classroom at JR Masterman Laboratory and Demonstration School. Mr. Cragg was a tall white man with the build and carriage of a former athlete and the kind of face that magazine writers of that day would call “ruggedly handsome.” He welcomed me, introduced me to the class and pointed to Jo, who was to become my locker mate and guide. At some point, some teacher or counselor explained to me that learning at Masterman was based on the Discovery method, which meant that we would have opportunities to experiment and learn things for ourselves, instead of rote instruction. Educators of that time were heavily influenced by psychologists such as Jerome Bruner and Jean Piaget who theorized about ways of structuring school and classroom culture in ways that were organic to the way that children learned to do such things as speak and problem-solve through immersive engagement with the surrounding world.

This would lead to a number of formal and informal experiments in everything from the configuration of furniture in the classroom, to new modes of in-class and out of class instruuction. Across the school district, some of these experiments would lead to the creation of all sorts of specialized programs, from a storefront schol annex of Gratz High, led by Marcus Foster, designed to keep teen mothers from dropping out of high school, to the creation of the Parkway program, a high school without walls that allowed students to use the city’s libraries, museums and other community resources as their classroom. As a laboratory and demonstration school, it was explained to us that many of these new ideas in education would be tried first on us, so that others could study the results and perhaps implement them elsewhere. Consequently, people from as as far away as Africa and Europe would occasionally visit our classes and observe what we were doing.

My first recollection of experiencing the method in practice in Mr. Cragg’s class was the class newspaper, “The 210 Express.” It was a mimeographed affair, planned, written, edited and produced by the students. I still have a copy of the issue that includes a brief item on my arrival in the class. What was even more exciting for me, though, was that I wrote a poem that was published in the newsletter. It was a melodramatic depiction of the siege of the Alamo called “Carry on, My Captain.” I cringe now at how bad it was, but I saw my name in print for the first time, and I had peers who thought that was cool.

There was more. The kids at Masterman came from all over the city. They were white, black, Asian, and some were even racially mixed. One boy said he was descended from Robert E. Lee, the leader of the Confederate troops, and he wasn’t too thrilled about it. I met Catholic and Jewish kids for the first time. There was even a Muslim girl and a girl who explained to us that she was a Black Hebrew. I ate my first bagel. Some of them were obvious prodigies, especially at music.  This being the 1960s, were socially aware. Vietnam, racial justice, and funding for education figured in our conversations, along with more typical kid fare: the latest music, tv shows, and gossip about which boy asked which girl whether he could “stand a chance.”  Had he seen the way we learned from each others’ backgrounds and developed a group ethos, Piaget would have been satisfied that we validated his theory about the potential positive impact of peer relationships on children’s social and moral development. As James Youniss put it:

“While [Piaget] is recognized for stimulating interest in the child as an active cognitive agent, little has been made of his proposal that children can construct a mutually understood principled morality which puts common benefit above individual interest.” (Youniss)

Writing for the 210 Express, along with experiences outside of school, started me on the path of thinking of myself as a writer. But I remember doing other activities that are now associated with teaching computing concepts to children.  In sixth grade math class, I recall playing with games and manipulatives, such as cuisenaire rods, which we used to illustrate problems with fractions, among other things.

We also had clear plastic containers that we used to measure the volume of things, illustrating concepts such as the conservation of numbers, weight mass and volume.  Piaget maintained the children understand this concept at a very young age, so I think the teacher’s interest was in making our inductions visible.

However, my favorite activities were two strategy games, Towers of Hanoi and Mancala. I now recognize these games as examples of algorithmic thinking. In Towers of Hanoi, the player is presented with three discs stack on the leftmost of three poles. The disks are arranged in size order, from smallest to largest. The challenge is to move the disks from the leftmost pole to the rightmost pole in the fewest moves.  At no time can a larger disk be placed on top of a smaller one.  It’s a very familiar game in the world of math of computer science. If you haven’t played it, try this virtual version from Dynamic Drive.

Mancala is the name for a collection of games called “Count and Capture” games. Mancala games use a board that is like an egg carton, and objects such as seeds or stones that are distributed in each of the cups in groups of four. Players can only move the pieces on their own side. They take turns picking up all of the stones in one cup on and distributing them, one at a time, in each successive cups in a counter-clockwise fashion. Depending upon the set of rules being used, players “capture” stones based on where they end up after distributing them. The goal is to capture the most stones. Math education researchers note that this game can help players explore subjects as simple as arithmetic and as complex as combinatorics .

So far, all of these experiences constitute creative approaches to learning traditional subjects, with opportunities for me to make serendipitous discoveries on my own.  However, it was our music teachers, Gloria Goode and Virginia Hagemann,  who took us to a new frontiers of personal growth and exploration. My next post will focus on their work.

“When I first get up in the morning I feel fresh and it feels like it would be a good day to me. But after I get in school, things change and they seem to turn into problems for me. And by the end of the day I don’t even feel like I’m young. I feel tired.”

The Me Nobody Knows: Children’s Voices From the Ghetto, Stephen M. Joseph, ed.  (first printed in 1970, reprinted in 2003)

The word that I had been admitted to Masterman, a public school for gifted children, came not a moment too soon. It was April, 1967, I was 10 years old,  I was considered one of the top students at Kearny Elementary School, but socially and emotionally, I was failing badly. Had I not been transferred to Masterman when I was, I am not sure how I would have coped with my growing sense of loneliness and isolation. Reflecting upon these experiences leads me to think about how a child’s interactions with home, school, neighborhood and the larger environment affects her perceptions of her place in the world, and her chances of overcoming its obstacles and seizing its opportunities.

In recent years, psychologists have advocated for models of child development that give central consideration to the role of culture and socio-economic status in shaping the way a child views the world and functions within it. Yvette Harris and James Graham, author of the 2007 book: The African American Child: Development and Challenges (Springer Publishing Company, New York, NY.) argue that this is especially important for understanding children of color.

I had never been accepted in Penn Town, the neighborhood in which I had lived since moving to Philadelphia from Camden, New Jersey at the age of six. To begin with, I soon learned that only a few of my peers had ever been to New Jersey, so I was something of a foreigner. Even though Camden was only a few minutes away by car, and we lived fairly close to the Benjamin Franklin bridge, not many families owned a car, and the public transportation services that shuttle between the two cities now hadn’t yet been built. I must have talked about Camden too much, because I remember a boy telling me that he had been to New Jersey once, and it wasn’t so special, so there!

My  father’s second-hand Chevy and my outsider origins weren’t the only problems. I lacked the social qualities that would have given me some currency among my peers. I was a slow, awkward runner, I couldn’t fight, and I had left Camden before I learned to jump double-dutch. Worse yet, I was double-handed, which meant that I couldn’t turn the ropes with a sufficiently reliable rhythm. To make matters worse, I was an only child, so I had no natural allies, and I had my own room. My father and stepmother wore second-hand clothes, but I had a new school wardrobe from Sears every year, and the latest toys. Worst of all, I was the teachers; pet.

I might as well have had a kick me sign tattooed on my forehead. As is true in every neighborhood, we had our designated bullies, and I was a favorite target for teasing and occasional beat-downs. For the longest time, I didn’t fight back; I’m not sure why. Nor did I know how to play the dozens, the ritual game of  insults built on race, class and gender stereotypes. I also had the annoying habit of questioning the logic of the taunts directed at me and others during an argument. It was common, for example, for a girl to say that she would “beat the black off” another girl. I couldn’t help wondering about that, because they also went around saying there was something wrong with looking too black. Following that logic, wouldn’t they consider it an improvement to have some of the “black” removed? Like the robot in “Lost in Space,” I spent a lot of time saying, “That does not compute.”

Eventually, there was a girl who declared that she would beat me up after school that day. She had been threatening to fight me since summer camp, and now the weather was cold enough for a coat. She had been a constant menacing presence. We met at the appointed hour, and, thinking that I would stand up for myself for once, I took a swing at her. She pulled my coat over my head and pulled my hair out  An excited crowd ringed around us and made enough noise that eventually some neighbor heard and got my stepmother to come rescue me.

Her response to the incident is telling. She brought me and the other girl into our apartment and told us that we were letting down the race by fighting like dogs in the street. She extracted apologies from us, and a promise to try to get along. I think a conversation with the girl’s mother followed, or at least attempted – that would have been the norm.  I think it was not long after that when my birthday coincided with the date of our regular Girl Scout meeting and she decided to host it at our place, complete with cake and ice cream. My tormentors were part of the troop. I can’t say we became friends after that, but I don’t recall any more beat-downs.

But by then, I carried the terror inside of me. Not just the fear of the neighborhood bullies, but the spectre of even worse violence. There were the tales of the tackheads, dark–skinned black girls with (snap fingers) that much hair who would supposedly grab girls, beat them, and carve up their faces to make them ugly. There were the gangs – in our neighborhood, there was 12th and Wallace and the Valley – gang geography was a required survival course in in everyone’s curriculum. During my childhood, the gangs went from zip guns to real guns, and before I left high school, some of my childhood neighbors, schoolmates and relatives were dead, or had suffered near-fatal injuries.

These dangers were mostly visited on boys, of course. In her book, Getting Played: African American Girls, Urban Inequality and Gendered Violence (NYU Press, 2010), sociologist Jody Miller described the violence and threats of violence routinely visited up African American girls and women in urban neigbborhoods.

Without going into detail, I will say that by the time I was ten years old, I witnessed or experienced actions that I now recognize as acts of assault and sexual harassment, and coercion, and I know that I was not alone. One did not talk about having been the victim of such experiences, although it was not unusual to hear a boy brag about having “felt somebody up,” or to hear that some group of boys, “ran a train” (gang-raped) a girl. That was usually told without sympathy for the girl, who was thought to have allowed herself to be in the wrong place at the wrong time.

Layered on top of all of this was the violence in the adult world – the real and rumored incidents of police brutality, the arrest of a neighbor’s father for killing someone in a bar fight, the occasional sight of a violent domestic argument that spilled out into the street.

I write of these things now because I recognize them as experiences that could have derailed me, and that did, over time, derail some of my peers. I also recognize that today, I could easily have met with the fate that befell Derrion Albert, the  16-year-old Chicago honor student who was stomped to death in September, 2009 as he was trying to escape a street fight that erupted as he was leaving school.

If we are serious about getting more young people from under-represented backgrounds into computing-dependent professions, our interventions must be sensitive the lived reality of children’s lives.

In another section of this work, I will explore these culturally sensitive models of child development and their implications in more detail. For now, I want to close with a presentation by Dr. John Rich, a trauma physician who heads the Center for Nonviolence and Social Justice at Drexel University. Dr. Rich’s work focuses on young black men who are victims and perpetrators of violence. Using an ethnographic approach, he tries to help us see and understand the human hurt at the heart of behavior that is beyond the comprehension of most people.
