The Case for Computing
By Gary S. Stager
The personal computer is the most powerful, expressive and flexible instrument ever invented. At its best, the PC offers learners a rich intellectual laboratory and vehicle for self-expression. Although computing has transformed nearly every aspect of society, schools remain relatively untouched.
This chapter is not about predicting the future. It is about the learning opportunities that exist today and may be overlooked. Computers and creativity are in dangerously short supply. The dearth of compelling models of using computers in deeper ways has created a vacuum now filled by a Dickensian approach to schooling.
When I read the growing mountain of educational technology standards I can’t help but wonder if these objectives could be satisfied without the use of a computer. The unimaginative use of school computers is symptomatic of larger crises in schooling, including what Seymour Papert calls, “idea aversion.” Over the past few decades I have enjoyed working at key moments in the intersection of learning and computers. My daily work is guided by an optimism rooted in experiences learning with computers and observing children doing the same. As much as this is the story of great promise and great disappointment, the children we serve sustain our enthusiasm to work harder to realize the learning potential of the digital age.
Ancient History – My Early Years of Computing
In 1976 I got to touch a computer for the first time. My junior high school (grades 6-8) had a mandatory computer-programming course for seventh and eighth graders. More than a quarter century ago, the Wayne Township Public Schools in New Jersey thought it was important for all kids to have experience programming computers. There was never any discussion of preparation for computing careers, school-to-work, presentation graphics or computer literacy. Computer programming was viewed as a window onto a world of ideas given equal status as industrial arts, music appreciation, art and oral communications.
The scarcity of classroom computers made programming a highly social activity since we were often leaning over each other’s shoulders in order to get in on the action.
Mr. Jones, the computer programming teacher, was scary in a Dr. Frankenstein sort of way. However, I was attracted by the realization that this guy could make computers do things!
Mr. Jones knew how elaborate computer games worked and would show us the code afterschool if we were interested. Once I understood how to read a computer program, I could THINK LIKE THE COMPUTER! This made me feel powerful.
The feelings of intellectual elation I experienced programming are indescribable. The computer amplified my thinking. I could start with the germ of an idea and through incremental success and debugging challenges build something more sophisticated than I could have ever imagined.
The self-awareness that I was a competent thinker helped me survive the indignities of high school mathematics classes. Mr. Jones helped me learn to think like a computer. The ability to visualize divergent paths, anticipate bugs, and rapidly test mental scenarios is the direct result of computer programming. This gift serves me in everyday life when I need hack my way through a voicemail system to reach a knowledgeable human, or get my car out a locked parking structure.
Perhaps Mr. Jones was such a great teacher because he was learning to program too – maybe just slightly ahead of us. (This never occurred to me as a kid since Mr. Jones knew everything about computers.)
A strong community of practice emerged in the high school computer room. We learned from each other, challenged one another and played with each other’s programs. We altered timeshare games, added ways to cheat and programmed cheap tricks designed to shock classmates. I even ran after school classes in BASIC for kids interested in learning to program.
Computers were to be used to make things at my high school, not as a subject of study. There was never a mention of computer literacy and owning a computer was unthinkable. The school computers were a place to lose our selves in powerful ideas.
We never saw a manual for a piece of software although we treasured every issue of Creative Computing – working hard to meticulously enter hundreds of lines of computer code only to have every single program be buggy. Since we had little idea what was impossible, we thought anything was possible. We felt smart, powerful and creative. We took Fortran manuals out of the public library for no other reason than to hold a connection to a larger world of computing – a world we were inventing for ourselves.
Bill Gates and Steve Wozniak, were involved in similar little ventures at the time. Many of the computing visionaries who changed the world had similar early experiences with computers. I remember the explosion of thinking and creativity I experienced programming computers and try to recreate the spirit of that computer-rich learning culture in every school I visit. Kids deserve no less.
In the mid-80s I was welcomed into the global “Logo community” and asked to present papers at places like MIT. This was pretty heady stuff for a failed trumpet player and mediocre student. Logo programming offered a vehicle for sharing my talents, expressing my creativity and engaging in powerful ideas with some of the leading thinkers in education. Seymour Papert’s scholarship gave voice to my intuitions visa-a-vis the tension between schooling and learning.
To this day, my work with adults and kids is centered around using computers as intellectual laboratories and vehicles for self-expression. To experience the full power of computing, the tools need to be flexible extensible and transparent. The user needs to be fluent in the grammar of the system whether it is text based, symbolic or gestural.
In 1989, Methodist Ladies' College, an Australian PK-12 school already recognized for its world-class music education, committed to every student having a personal laptop computer. By the time I began working with MLC a year later, 5th and 7th graders were required to own a laptop. The "P" in PC was taken very seriously. Personal computing would not only solve the obvious problems of student access, low levels of faculty fluency and the costs associated with the construction of computer labs - the PC would embody the wisdom of Dewey, Vygotsky and Piaget. Logo, because of its open-endedness and cross-curricular potential, was the software platform chosen for student learning. The potential of Logo as a learning environment that would grow with students across disciplines and grade levels could only be realized with access to ubiquitous hardware. This justified the investment in laptops.
MLC principal, David Loader, understood that the personal was at the core of any efforts to make his school more learner-centered. He was not shy in his desire to radically reinvent his school. Bold new thinking, epistemological breakthroughs, sensitivity to a plurality of learning styles, increased collaboration (among teachers and children) and student self-reliance were expected outcomes of the high-tech investment. Teachers learning to not only use, but program, computers would acquaint themselves with the type of “hard fun” envisioned for student learning.
If the computer were to play a catalytic role in this educational shift, it was obvious that the computers needed to be personal. Truly creative and intellectual work requires freedom and a respect for privacy. Quality work is contingent on sufficient time to think, to experiment, to play. The laptop can only become an extension of the child when it is available at all times. Therefore, there was never any debate about laptops going home with students. Time and time again, the most interesting work was accomplished during the student's personal time.
Laptops were a way to enable student programming “around the clock” and make constructionism concrete.
MLC was a magical place during the early nineties. Every aspect of schooling was open for discussion and reconsideration.
When I expressed concern over the gap between classroom reality and the rhetoric proclaiming the school’s commitment to constructionism, the principal supported my desire to take dozens of teachers away for intensive residential professional development sessions. After all, constructionism is something you DO as well as believe. You cannot be a constructionist who subcontracts the construction. “Do as I say, not as I do,” would no longer cut it.
A renaissance of learning and teaching catapulted MLC and the subsequent Australian “laptop schools” to the attention of school reformers around the world.
We were ecstatic when "laptop" students began to adorn their computers with their names written in glitter paint. This signaled appropriation. The computers mattered. Success.
The early success of MLC and the many other “laptop schools” to follow were a realization of the dream Seymour Papert and Alan Kay held for decades. In 1968, computer scientist Alan Kay visited Seymour Papert at MIT. Papert, a protégé of Jean Piaget, a mathematician and artificial intelligence pioneer was combining his interests by designing computing environments in which children could learn. Kay was so impressed by how children in Papert's Logo Lab were learning meaningful mathematics that he sketched the Dynabook, a dream of portable computers yet to be fully realized, on the flight home to Xerox PARC, a leading high-tech thinktank.
Kay set out to design a portable personal computer for children on which complex ideas could come alive through the construction of simulations. Dr. Kay recently remembered this time by saying, "More and more, I was thinking of the computer not just as hardware and software but as a medium through which you could communicate important things. Before I got involved with computers I had made a living teaching guitar. I was thinking about the aesthetic relationship people have with their musical instruments and the phrase popped into my mind: an instrument whose music is ideas."
Kay’s poetic vision resonated with my memories of Mr. Jones, summer camp and my own experiences programming in Logo.
“One of the problems with the way computers are used in education is that they are most often just an extension of this idea that learning means just learning accepted facts. But what really interests me is using computers to transmit ideas, points of view, ways of thinking. You don't need a computer for this, but just as with a musical instrument, once you get onto this way of using them, then the computer is a great amplifier for learning.”
At-risk and high tech
For three years, beginning in 1999, I worked with Seymour Papert to develop a high-tech alternative learning environment, the Constructionist Learning Laboratory (CCL), inside the Maine Youth Center, the state facility for adjudicated teens. This multiage environment provided each student with a personal computer and access to a variety of constructive material. The experience of trying to reacquaint or acquaint these previously unsuccessful students with the learning process teaches us many lessons about just how at-risk our entire educational system has become.
The intent of the project was to create a rich constructionist learning environment in which severely at-risk students could be engaged in long-term projects based on personal interest, expertise and experience. Students used computational technologies, programmable LEGO and more traditional materials to construct knowledge through the act of creating a personally meaningful project. The hypothesis was that the constructionist philosophy offers students better opportunities to learn and engage in personally meaningful intellectual development. The computer was the magic carpet that would allow these children to escape their history of school failure.
Students in this alternative learning environment routinely suffered from what Seymour Papert called,“the curious epidemic of learning disabilities.” Kids with low or non-existent literacy skills were able to invent and program robots capable of making decisions and interacting with their environment. Robo Sumo wrestlers, interactive gingerbread houses, card dealing robots, luggage sorting systems and temperature-sensitive vending machines capable of charging a customer more money on hot humid days were but a few of the ingenious inventions constructed with programmable LEGO materials. Students also designed their own videogames, made movies and explored the universe via computer-controlled microscopes and telescopes. They wrote sequels to Othello and published articles in programming journals. These kids proved that computing offered productive learning opportunities for all kinds of minds.
One child, said to be completely illiterate, wrote a page of program code the night before class because an idea was burning inside of him. Another “illiterate” youngster, incarcerated for more than half of his life, was capable of building dozens of mechanisms in the blink of an eye and installing complex software. His ability to program complicated robots presented clues about his true abilities. A week before he left the facility, this child, so accustomed to school failure, sat down and typed a 12,000-word autobiography.
Tony’s adventure is also a tale worth telling. He had not been in school since the seventh grade and indicated that none of his peer group attended school past the age of twelve or thirteen. In the CLL he fell in love with robotics and photography at the age of seventeen.
During the spring of 2001, the MYC campus was populated with groundhog holes. To most kids these familiar signs of spring went unnoticed, but not for the "new" Tony.
Tony and his new assistant, "Craig," spent the next few weeks building a series of what came to be known as "Gopher-cams." This work captured the imagination of the entire Maine Youth Center. Tony and Craig learned a great deal about how simple unanticipated obstacles like a twig could derail days of planning and require new programming or engineering. These students engaged in a process of exploration not unlike the men who sailed the high seas or landed on the moon. While they never really found out what was down the hole, they learned many much more important lessons.
Robotics gives life to engineering, mathematics and computer science in a tactile form. It is a concrete manifestation of problem solving that rewards debugging, ingenuity and persistence. The LEGO robotic materials promote improvisational thinking, allowing even young children to build a machine, test a hypothesis, tinker, debug, and exceed their own expectations. As often experienced in programming, every incremental success leads to a larger question or the construction of a bigger theory. This dialogue with the machine amplifies and mediates a conversation with self.
Digital technology is a critical variable in the transformation of reluctant learners. Self-esteem, or even academic grades, might have been enhanced through traditional activities. However, the availability of computationally-rich construction materials afforded the learners the opportunity to experience the empowerment associated with the feeling of wonderful ideas. For the first time in their lives, these children experienced what it felt like to be engaged in intellectual work. This feeling required a personal sustained relationship with the computer and computationally-rich objects to think with such as LEGO and MicroWorlds. All students deserve the chance to make important contributions to the world of ideas, and must be given the means to do so.
State of the art?
Much needs to be done to ensure that all students enjoy the quality of experience offered by the best laptop schools, online environments and the CLL.
Somewhere along the line, the dreams of Kay, Papert and Loader were diluted by the inertia of school. Detours along the road to the Dynabook were paved by the emergence of the Internet and corporate interest in the laptop miracle.
Until the explosion of interest in the Internet and Web, individual laptops offered a relatively low-cost decentralized way to increase access to computers and rich learning opportunities. The Net, however, required these machines to be tethered to centralized servers and an educational bureaucracy pleased with its newfound control. Computing costs soared, data and children were either menaced or menaces. Jobs needed to be protected. The desires of the many often trumped the needs of the learner.
Microsoft generously offered to bring the laptop message to American schools, but their promotional videos pushed desks back into rows and teachers stood at the front of classrooms directing their students to use Excel to calculate the perimeter of a rectangle. Over emphasis on clerical “business” applications – were manifest in elaborate projects designed to justify (shoehorn) the use of Excel or Powerpoint in an unchanged curriculum. Many of these projects have the dubious distinction of being mechanically impressive while educationally pointless. Our gullible embrace of false complexity increases as the work is projected in a darkened classroom.
I’ve developed Murray’s Law to describe the way in which many schools assimilate powerful technology. “Every 18 months schools will purchase computers with twice the processing power of today, and do things twice as trivial with those computers.”
There is a fundamental difference between technology and computing, which can be seen in the words themselves. One is a noun, the other a verb, What we saw students do with technology at the CCL was active, engaged, compelling, sophisticated learning. They were computing, and similar experiences for all students can transform the experience of school.
What are you really saying?
I know that many of you must be thinking, “Does Gary really believe that everyone should be a programmer?” My answer is, “No, but every child should experience the opportunity to program a computer during her K-12 education.” Critics of my position will say things like, “Not every person needs to program or will even like it.” To these people I suggest that not every kid needs to learn to write haiku or sand a tie rack in woodshop. However, we require millions of children to do so because we believe it is either rewarding, of cultural value or offers a window onto potential forms of human expression.
Despite our high-tech society’s infinite dependence on programming and the impressive rewards for computing innovation, many people find the notion of programming repulsive. Everyone wants their child to earn Bill Gates’ money, but only if they never have to cut a line of code. Educators especially need to get past this hysteria rooted in fear and ignorance for the sake of the children in our care. (this sentence is optional if you feel it is inflammatory)
I do not understand why anyone would question the value of offering programming experiences to children.
It is unseemly for schools to determine that a tiny fraction of the student population is capable of using computers in an intellectually rich way. The “drill for the test” curriculum of the A.P. Computer Science course serves only a few of the most technically sophisticated students. That is elitism.
Children enjoy programming when engaged in a supportive environment. The study of other disciplines may be enhanced through the ability to concretize the formal. For example, complex mathematical concepts become understandable through playful manipulation, graphical expression of abstractions or the application of those concepts in service of a personal goal. It would be difficult to argue that mathematics education, at the very least, would not be enriched through programming.
Schools need to make a sufficient number of computers with powerful software available for the transparent use of every child across all disciplines. Schools also have an obligation to offer a more inclusive selection of courses designed for a more diverse student body interested in learning with and about computers. Courses in software design, digital communication, robotics, or computer science are but a few options. The Generation Y program, in which students lend their technological expertise to teachers who want to integrate technology into their lessons provides another outlet for authentic practice.
I wonder when the educational computing community decided to replace the word. computing, with technology? The Computing Teacher became Learning and Leading with Technology, Classroom Computer Learning begot Technology and Learning Magazine. Conference speakers began diminishing the power of the computer by lumping all sorts of objects into the catch-all of technology. Computers are in fact a technology, but they are now spoken of in the same breath as the blackboard, chalk, filmstrip projector or Waterpik. Computing was never to be mentioned again in polite company.
I recently read the conference program for a 1985 educational computing conference. The topics of discussion and sessions offered are virtually the same as at similar events today. The only difference is that all mentions of programming have disappeared from the marketplace of ideas.
It seems ironic that educators fond of reciting how kids know so much about computers act as if the computer was just invented. We should be unimpressed by breathless tales of children web surfing or using a word processor to write a school report. My standards are much higher. We will cheat a second generation of microcomputer-age students if we do not raise our game and acknowledge that so much more is possible.
If we concur that kids are at least comfortable with computers, if not fluent, then teachers have a responsibility to build on the fluency of computer-savvy kids. This is a classroom gift, like an early reader, a natural soprano or a six year-old dinosaur expert. It is incumbent on schools and their personnel to steer such students in more challenging and productive directions. Teachers have an obligation to respect the talents, experience and knowledge of students by creating authentic opportunities for growth.
If the youngest children can “play” doctor, lawyer, teacher or fireman, why can’t they imagine themselves as software designers? Open-ended software construction environments designed for children, like MicroWorlds, make it possible for children of all ages to view themselves as competent and creative producers of knowledge. Too few students know that such accomplishments are within reach. This failure results from a leadership, vision, and professional knowledge deficit.
While school computing fades from memory, keyboarding instruction inexplicably remains a K-12 staple from coast to coast. Computer assisted instruction, schemes designed to reduce reading to a high-stakes race and low-level technical skills dominate the use of computers in schools. In the hands of a clever curriculum committee, “uses scroll bars” can be part of a nine-year scope and sequence.
Examples of kids composing music, constructing robots, or designing their own simulations are too hard to find. More than a quarter century has passed since Mr. Jones taught me to program. Yet, children in that school are now compelled to complete a keyboarding class. There can be no rational justification for so blatant a dumbing-down of the curriculum.
Computing Changes Everything
There are so many ways in which children may use computers in authentic ways. Low-cost MIDI software and hardware offers even young children a vehicle for musical composition. The 1990 NCTM Standards indicated that fifty percent of mathematics has been invented since World War II. This mathematics is visual, experimental and rooted in computing. It may even engage kids in the beauty, function and magic of mathematics.
In Seeing in the Dark: How Backyard Stargazers Are Probing Deep Space and Guarding Earth from Interplanetary Peril, author Timothy Ferris describes how amateur astronomers armed with telescopes, computers and Net connections are making substantive contributions to the field of astronomy. For the first time in history, children possess the necessary tools to be scientists and to engage in scientific communities.
MacArthur Genius Stephen Wolfram has written a revolutionary new 1,280 page book, A New Kind of Science. The book illustrates his theory that the universe and countless other disciplines may be reduced to a simple algorithm. Scientists agree that if just a few percent of Wolfram’s theories are true, much of what we thought we knew could be wrong and many other cosmic mysteries may be solved. Wolfram believes that a human being is no more intelligent than a cloud and both may be created with a simple computer program.
A New Kind of Science starts with very a big bang.
"Three centuries ago science was transformed by the dramatic new idea that rules based on mathematical equations could be used to describe the natural world. My purpose in this book is to initiate another such transformation, and to introduce a new kind of science that is based on the much more general types of rules that can be embodied in simple computer programs."
You do not have to take Wolfram’s word for it. With the $65 A New Kind of Science Explorer software, you and your students can explore more than 450 of Wolfram’s experiments. The visual nature of cellular automata - the marriage of science, computer graphics and mathematics – allows children to play on the frontiers of scientific thought while trying to prove, disprove or extend the theories of one of the world’s greatest scientists. The intellectual habits required to “think with” this tool are rooted in computer programming.
I recently told Alan Kay that while I was hardly a mathematician, I knew what it felt like to have a mathematical idea. He generously replied, “Then you are a mathematician, you’re just not a professional.” The work of Seymour Papert shows us that through the explicit act of computing children can too be mathematicians and scientists.
“If you can use technology to make things you can make a lot more interesting things. And you can learn a lot more by making them. …We are entering a digital world where knowing about digital technology is as important as reading and writing. So learning about computers is essential for our students’ futures BUT the most important purpose is using them NOW to learn about everything else. “ (Papert 1999)
We can neutralize our critics and improve the lives of kids if we shift our focus towards using school computers for the purpose of constructing knowledge through the explicit act of making things - including: robots, music compositions, digital movies, streaming radio and simulations. Children engaged in thoughtful projects might impress citizens desperate for academic rigor. Examples of competent children computing bring many current educational practices into question. Emphasizing the use of computers to make things will make life easier for teachers, more exciting for learners and lead schools into what should be education’s golden age.
Why Should Schools Compute?
Computing offers an authentic context for doing & making mathematics
Traditional arithmetic and mathematical processes are provided with a genuine context for use. New forms of mathematics become accessible to learners.
Computing concretizes the abstract
Formal concepts like feedback, variables and causality become concrete through use.
Computing offers new avenues for creative expression
Computing makes forms of visual art and music composition possible for even young children while providing a canvas for the exploration of new art forms like animation. A limitless audience is now possible.
Computer science is a legitimate science
Computer science plays a revolutionary role in society and in every other science. It should be studied alongside biology, physics and chemistry.
Computing supports a plurality of learning styles
There are many ways to approach a problem and express a solution.
Computing offers preparation for a plethora of careers
There is a shortage of competent high-tech professionals in our economy
Computing gives agency to the user, not the computer
Rather than the computer programming the child, the child can control the computer.
Debugging offers ongoing opportunities to enhance problem-solving skills
Nothing works correctly the first time. The immediacy of concrete feedback makes debugging a skill that will serve learners for a lifetime.
Computing rewards habits of mind such as persistence, curiosity and perspective
Computers mediate a conversation with self in which constant feedback and incremental success propels learners to achieve beyond their expectations.
