Technology In Primary Education, Boon Or Bane?
code_rage writes "This article in the San Francisco Chronicle attacks the zealous use of computers in grade school. In a time of teacher layoffs, San Francisco schools are buying 450 new computers with federal and state grants. The effects on education go beyond the initial costs: educational methods are suffering, as children are learning PowerPoint and teachers are becoming unpaid SysAdmins and content censors. This article is a well-written and brief update to Cliff Stoll's book High Tech Heretic: Why Computers Don't Belong in the Classroom." Update: 12/01 00:40 GMT by T : Ooops II-- "Classroom" is now correctly spelled.
First off, I'd love to have a kind of computer 450 of which cost just short of 1M$ -- that would be almost 2K$/computer. Not exactly a budget cut type of purchase, if you ask me :-)
Second, they would not be having the technical problems they do now, had they not gone with that infamous OS from Redmond, plus they would save much on the OS/support costs.
But this is all secondary. The most important fallacy in blaming the computers for dumbing the classrooms is in that the teachers don't have a clue what the computers are for. Where I went to school, the games were prohibited. You had do write you program using pen and paper. Then you had to prove (in D. Knuth's way) to the teacher that it works. Only after that you were allowed to type your code in and try compiling it.
As for the web, IM, chatrooms, etc, one has to be blind not to recognize this as entertaintment which is not the purpose of the school. I would not have internet connections from classroom computers. Local network is fine, but one would have to prove than (s)he really needs Internet access for that project before the access is granted.
It's like bringing TVs to school. While they can definitely be a source of important information, hardly anyone would fancy buying TVs for the school to close information divide :-) How is the (internet and games enabled) computer different in that regard?

...is what happened to the classical forms of education. Young stundents in their mid-teens could do complex mathetmatics in their heads, and knew classical Greek and Latin fluently in some upper-scale schools in the 1800s. Now it's not uncommon for students to graduate without a complete grasp of the English language -- much less math, foreign language, or anything else.
Honestly, I think that technology should be taught, but not used to teach, at least not up until a certain age. The classic forms of learning reading, writing, and arithmetic worked -- and they worked much better than any new fangled and more expensive method we have today.
It's not about the methods, it's not about the standardized tests. It's about the learning. Schools need to be reminded of this.
Instead, all they care about is high scores on the standardized tests. Damn the students beyond that.
If we want public schools to improve, funding should go toward increasing teachers' salaries. After all, if you graduate from college with a degree in chemistry, are you going to teaching science in a rural or inner-city school system for $30,000 a year or go to work for that pharmaceutical company for twice as much?

my weblog: apropos of something
And now physics is indistinguishable from a Hollywood special effects extravaganza, and carries about as much reality to the student. Hate to be a luddite, but there's no substitute for running your own experiments and demos in situ. Obviously some are going to be out of reach, but multimedia is no subst for the real thing when it's at all possible.
Trouble making decisions? Just flip for it.
* The people who invented and commercialized that tv didn't have tv in their classrooms.
* The people who put the men on the moon didn't have computers in their classrooms.
* The people who invented the computer didn't have computers in their classrooms.
* The people who cured polio, mumps, rubella, diptheria, pertussis, tetanus, etc. didn't have computers in their classrooms.
* The people who split the atom didn't have computers in their classrooms.
* Shakespear, Milton, Dickens, Twain, Dostoyevski, Joyce, Capote, Hemmingway, etc., didn't have computers in their classrooms.
Is this not yet another band-aid we're trying to apply to our very sick public education system? Give 'em all computers and maybe some of the real problems (such as our distressingly low international rankings in math and reading) will magically disappear. The kinds of skills children need to learn in grammar school aren't very amenable to computers. How to read and retain effectively what's been read, the mysteryious workings of numbers, even the construction of a blobby salt map of the Roman Empire--all these are best left in the hands of a skilled teacher. A computer can't see the perplexed look on the face of a child in the back row.
It seems to me that computers can be added to the curriculum as they are required, and used for their logical and reasonable purposes. When kids start doing "reports" in the middle grades, computers become tools for research. Later on, they can serve many purposes, with those kids who show interest and aptitude learning to write programs, while everybody learns the basic word-processor/spreadsheet/database triad that keeps the office world going.
It seems to me that simply throwing them into an already-troubled system simply robs kids of "face time" with their teachers while lulling the rest of us into thinking all's well in our schools. All's decidedly not well.

DUCT TAPE: The Election Supervisors' Secret Weapon
Yeah, me too. And you know what? When it comes to teaching, the TV is a double edged tool. It can be used effectively, but there's also the danger of sitting back and letting the TV do all the work. I had a professor in college (!) who would lecture for 10-15 minutes, and then plug in a documentary. Some of them were pretty good documentaries, but they were still no substitute for a real teacher who can answer questions.
Wrong. We don't need any of them. Education could proceed with nothing more than a teacher and a student, and maybe a stick to draw in the dirt. Televisions and computers and even books are just tools to make teaching and learning easier. Used in moderation, they can be phenomenally useful; but you can't substitute a machine for a teacher, especially at the earlier levels. Personally, I'd be happier if the elementary schools in this country would concentrate on strong reading skills, strong mathematical ability, strong writing skills, and a general grounding in science and history. If computers are part of that process, great! But they should be a supplement, not a staple. There's plenty of time for more computer-centric education during the later years of education (eg ages 12 and up).
What really worries me is that these schools are getting ripped off. A million dollars for 450 computers? That seems awfully steep. Since the article specifies that the cash is divided among multiple schools, I assume that the 1 million is all or mostly spent on hardware and software, rather than salaries for support staff or such. That means they're paying approximately $2,200 per computer, which is absolutely ludicrous. That's the kind of money you spend on a professional workstation. Either these schools are buying systems that are WAAAAAAY over-powered for their needs, or they're getting totally ripped off on software prices.
Heck, I could build those same 450 systems for approximately $320,000 using off-the-shelf commodity hardware and Linux (perhaps Debian Junior, a kid-oriented flavor of Debian). Budget another $120,000 to employ a code monkey for a few years to work on any rough edges in the systems. The rest of the money could go to other school programs in need of funding -- music, art, PE, free lunches for poor kids. It really pisses me off to see our schools spending huge amounts on exorbitantly priced licenses for proprietary software, when those funds could be better spent on other areas.
I took my BS in Comp Sci and used it to become a teacher. Honestly you want to know the biggest fault of the system that I see RIGHT NOW is?
I have people who can't turn a TI calculator off telling me I have to use those same Calculators in my classroom. Meanwhile, at the beginning of the year I had to show kids in Trigonometry how to do long division, square roots, and exponents before I could even begin to touch on sin, cos, and tan.
Yeah technology is wonderful at helping people bridge the concrete with the abstract. But if they have no clue about the basics do you think technology will save them.
Personal observation #2: All you parents and future parents pay attention to this. The kids who succeed are the ones whose parents actually show interest in their kids work. Some things that accomplish this is to make sure they are doing their homework, know what classes they are taking, and actually go to parent conferences.
Final observation: It'll get better as the hierarchy at the schools themselves end up being more computer adept. You wouldn't believe how useful a Smart-Board and other technologies can be in the classroom if the teacher knows how to use them. Same goes with calculators and other technologies. Right now there is a feeding frenzy going on with the idea that every child needs to learn technology out the yin-yang while in high-school. Once people start realizing that most of what we teach them they will pick up on their own if left to their own exploration.
BTW: All you unemployed Computer geeks. You might want to look at your state's Non-Traditional Licensing office and go into teaching. It is a great job. (Except for the pay but hey, I get vacation out the wazoo.)
Without the calculator theres no way 90^ of us could do calculus.
...some things are impossible to teach the average class without the help of computers and as classes have hundreds of students it will be impossible to teach something like multivariable calculus to a bunch of 8th graders.
Even with a calculator, 90% of us can't do calculus. Hell, I'd be surprised if 90% of Americans can do basic arithmetic with fractions even with the assistance of a graphing calculator, a computer running Mathematica, and a math tutor! Honestly!
Once you give a calculator to a child, then your bound to show them how to use it. That's twice as much work -- learn the math & learn the box. Each calculator has its own menus/features etc. So either every student has a different calculator (which makes it difficult to lecture how to use it) or the class standardizes on one machine (so that the student won't be able to operate the myriad of other calculators). We call that PROGRESS.
Without the word processor half of us could not write a paper with perfect grammar.
Again, even WITH a word processor, a significant number of people can't write a paper with PERFECT grammar. Word processors can check the spelling, and not much more. Do they fix run-on sentences, comma splices, improper selection of words?
What a laugh. Show me where they teach 8th graders multivariable calculus. What planet do you live on?!? Anyone that needs to learn this stuff should be more than capable of learning it with pencil and paper. I hold a M.S. in mathematics, and even the lowly calculator was forbidden in every math class, with the exception of two courses in numerical analysis. Give me a break!
You made an interesting distinction: the secretary compared to the (implied) programmer / power user.
Basic user skills are not very related to language, in this we agree. Those skills can be learned by most anyone at any time. However these are not the skills that people need to make the most of their computing experiences. Only having these sorts of skills are a large part of the problem we have with computing today.
Nobody growing up today should be considering the nature of a computer as a 'magic box'. Early on, this was true because computing was new enough, but today that has changed.
Computers are basically everywhere today and they are only going to become more pervasive in the years to come. Understanding the core nature of computing is important and is related to language more than you are giving it credit for.
You are dead on in the last paragraph regarding perspective. Most schools are missing it and the questions you raise are good ones more folks should be asking before sending their kids into the computer enabled classroom.
(BTW, I believe we should not see computer use prior to 6th grade. --Kids need time to gain mastery of the three R's before getting to use the computer. If you think of the computer as a tool to help think, which is computing when you really think about it, one must be capable of thinking on their own in order to get the proper benefit of the tool.)
What students need to know? (6th grade - HS)
(About computing)
0. Computers do exactly two things, in general. They add numbers together and move numbers around.
1. The nature of information and how it is processed. Basics only here, RAM ROM CPU Storage, I/O concepts.
2. Why base 2 numbers? Logic AND, OR, NOT, XOR and others. Make kids give instructions for general tasks using these operators when they make sense. Use plain english for these and include problems and situations that require some simple basic logic to express.
3. The representation of things using numbers. This is where computing is a lot like language. We make up new words all the time to define and convey ideas in a shorthand way. --This makes things easier for us. Example: Joe is an asshole. What combination of words replace 'asshole'. A large part of the problem understanding computers is directly related to the concepts inherent in this type of discussion.
4. Types of computers. Embedded, complex, cluster, personal. Compare and contrast the microwave controller, personal computer, cell phone computer, game machine. How are they different? What representations of data are important to their function?
5. Computing concepts. Basic programming using some semi-natural language. Anybody should be able to ask a computer to perform many basic tasks. Everyone should have written a simple program or two to get the computer to do exactly what they want instead of learning which software to purchase or how to combine functions to get the same result. Text files should be important.*
This is not a UNIX thing, or an anti GUI thing, it is a language thing. Learning how to manupulate representations of things we find important in a form the computer is good at processing in a meaningful way. Having grown up on the 8bitters, this comes naturally, on todays computers this information needs to be taught because the higher level representations possible today allow the core of what is happening to be glossed over too easily. --"Magic Box"
6. Software. All software is simply information just like anything else we put into a computer. What makes it different from data?
7. Ethics. The computers of today, for the most part, do what we tell them to. Lets hope that continues to be true. Given this, what responsibilities do we have? Compare and contrast 'hacking' to 'cracking'. Why are they different and how important is that difference?
8. Culture. Once people begin using networked computers (0-6 do not require th
