Computers Not Working In Education

salimfadhley writes "BBC Radio 4's current affairs program 'Analysis' is reporting [realaudio] [txt transcript] on emerging evidence that computers have harmed, rather than helped educational progress. There is still much debate among even the most enthusiastic supporters of schools technology about how computers should best be used. Despite record investment in computers in the USA and UK, recent studies (not the ones funded by educational software companies) have shown a significant drop in core subjects (Math, English) in schools that place strong emphasis on Information Technology. Evidence also suggests that whilst information technology has great potential in the classroom, teachers have not yet found better use for computers than as a big library. Very few schools have been able to use the new technology for cultural exchange, or to build practical educational networks with other schools. Teachers do not know whether computers should be seen as an exciting but peripheral educational 'accessory', or if computers can actually be used to solve the most pressing problems of literacy and numeracy - the sorts of things that get kids through exams." The Economist had a similar article a month or two back, about Israeli schools that had similar results, along with an interesting comparison between how people see computers now, and how people in the early 20th century saw film strips in the classroom.

      Seriously though, I think that in the 80s a huge importance was placed upon computer education. The common notion was that everyone will need to know how to operate a computer later in life.

      Well, they were partially right. Everyone should know how to operate a computer, but for practical purposes in High School education, that's a 2 hour class with perhaps a semester course in typing.

      A computer will do much of the work for you. It will do your math, check your grammar, and allow you to do research from your home. The problems here are obvious. There is little need to do things for yourself. I've found that most children do not have the discipline to willingly learn advanced math and grammar on their own. The problem is two-fold here though because many parents don't have the discipline to discipline their kids.

      As for research, I'll be quite blunt. The net is a poor tool for younger students. There is too much opinion and just plain bull shit on the web to be of great use. It takes a more seasoned approach and a level head to be able to filter out the crap, and I don't think the majority of high school kids benefit by using it to do their research work.

      It's not a one-size fits all situation however, and it's difficult to administer a solution. If I were in charge though, I'd have one guideline: If your kid has ADD or some other modern learning disability that requires he get special attention in school, his computer access should be limited. Afterall, the kid's problem is distraction, so a computer (with web access is even worse) is definitely going to be a greater distraction than a learning tool.

      I programmed in logo and that was totally useless.

      Have you considered that although the language is largely useless for building applications, it's a pretty useful tool for teaching children about how computers work? Logo is good at encouraging modular programming concepts, and is reasonably interactive -- perfect for 3rd graders. And it sounds like they did some stuff that a 3rd grader would find interesting, like creating shapes on the screen.

      I'd teach someone at that age Basic not Logo. In Middle School I'd move on to Visual Basic and or C.

      This plan isn't going to work for the masses. Yes, there are kids that can learn to program effectively in C during the Middle School years. But many of them cannot grasp it. Of those that are capable, many of them wouldn't be interested in programming -- they'd rather play games. There's a reason why advanced mathematical logic and proofs isn't usually taught until high school. It's because there are some significant changes during adolescence in the prefrontal cortex, frontal lobes and parietal lobes of the brain. The result of these changes is sharper focus and attentiveness, improved executive function and planning, and better spatial processing. Therefore, schools tend to avoid teaching subjects that require these skills until after most of the students are ready.

      This would be computer science and they'd learn a few concepts which might help them in understanding algebra

      While this is true, I believe it might be better for them to learn the concepts of algebra without the aid of a computer. I've found that among high school students, those that struggled the most to learn how to program had a weak background in algebra. However, let me point out that my evidence in this area is merely anecdotal. IANAEBIKMOT (I am not an educator, but I know many of them). :-)

      Computers should be used as a tool to teach math, not as a tool to teach Computers.

      I cannot disagree more. Students should be learning the foundations of math without interference from devices that help them perform the math. For the same reason, calculators were normally banned during my school years until students started doing trigonometry and calculus. This was intended to force them to learn the concepts of the math rather than relying on a machine. Want to see what happens when students start using calculators? Take a look at today's teenagers working a cash register who can't even count change back to you properly. I don't see computers as improving this situation at all.

      Teachers today treat Computers like they are mysterious

      I agree with you here. I think that perhaps the single biggest problem is that the teachers themselves are not familiar enough with computers.

      A web connected Tablet connected to everyones desk would be far more efficient than notebooks and the current tools, and a smartboard is far more efficient than a chalk board

      I agree with you here. This would be a tremendous advance in classrooms.

      you can learn math just fine with just a calculator, you can learn math with a computer

      As I said before, I disagree with this. Today's teens are evidence enough. Most of the teenagers I know are using calculators in their math classes and couldn't do math properly to save their lives.

      And before some fool comes and says "You dont know math if you use a calculator, you dont know math is you use a computer"

      The danger isn't in using a calculator or computer. The danger is in using one before you've developed efficient skills at doing it yourself. The best way to improve your math skills is to practice.

      Theres a difference between knowing math, and knowing how to work with numbers, number crunching is not knowing math.

      Although this is somewhat true, exercising your brain on some number crunching greatly improves your understanding and efficiency in mathematics. When I was in college, I received a dramatic lesson in this. One of my professors put up a problem that required calculus to solve. The specifics of the problem were dictated by the students, but we were left as a class to solve the problem. All of us had calculators except the professor, who was using a slide rule. He was able to solve the problem accurately on his slide rule before any of us could even finish typing in the numbers to the first part on our calculators. Even those of us with calculators that performed integration were no match for him. Why? Because he did large portions of the math in his head, only employing the slide rule where necessary. After witnessing that demonstration, I stopped using my calculator for all but the most difficult tasks. When I go to a grocery store, I make it a point to add up the prices of what I'm buying in my head -- just to keep my brain working.

      So, where do I think we need to see computers? We're already seeing them in use as a library of information. This is a good start. Being connected with people all over the world helps to break down cultural barriers, but I believe this kind of use happens best outside of school. Learning to program is an excellent idea, as most people will use it in one form or another in the business world. How about taking and grading tests? Also, computers are great for self-paced learning, and as such could be the key for allowing students with a wide range of capabilities to learn to the best of their ability.

      Yeah, I think this is one of the greatest problems we face today. Too many teachers don't bother to teach the fundamentals any more, because it's easier to teach the abstraction and they don't have to listen to the kids complaining about it being too hard like they did when they had to learn multiplication tables. It really sickens me when I hear of people like Rosie O'Donnel saying "nobody should have to learn math any more" and of teachers who wholeheartedly agree.

      The thing is, this isn't just a problem in formal education. A lot of things are becoming more abstracted these days, and people who should know better often take the path of expedience and only bother to learn the abstraction. How many "web developers" out there know how to drag-and-drop in Visual Interdev, but couldn't tell you the first thing about HTML syntax or HTTP authentication? How many MCSEs can only do something as long as there's a GUI widget for it and nobody asks them to explain what else it may affect? How many auto mechanics are left who can do anything but run a computer diagnostic and do what the shop manual says? Even McDonald's has abstracted away the process of cooking hamburgers to the point that nobody behind the line knows how to do it without having a chime to tell them when to take the patties off the grill.

      Of course, the real problem is that most things are increasing in complexity to the point that these abstractions are necessary, and the increase in complexity is what's driving progress. The complexity and abstractions are only going to increase as long as we as a species choose technological innovation as our holy grail.

While these PC-Tutor like programs may be fine for some students we have found that the role of the computer in the classroom is changing. Today's technically literate students use PC's in the same ways adults use them in the workplace and in college.

    There are four main uses that we have identified:

    1. Collaboration - Our students use PC's for e-mail, sharing files to complete group projects, passing on links to web sites and articles from on-line databases. It's not uncommon to have two or three students working together with one serving as the "record keeper" keeping track of information which is later saved and shared electronically with the other group members. Isn't this the way you work as an adult? For our students, their /home folder becomes a virtual notebook where they organize their important stuff and the /public share becomes a means of exchange.

      Our students were quick to incorporate a networked environment into their day to day school life. They use it to get their work done and have found many ingenious social adaptations as well. As tools for collaboration, networked PC's are changing the classroom in the same ways they have changed the workplace.

    2. Communication - The most used applications in our classrooms are not the flashy, multimedia based, tutorial programs that you see in the educational sections of software stores. When our students are working they use the same programs the rest of the world uses, word processing, e-mail, spreadsheets and presentation software. There is little room for the computer as tutor concept in today's busy classroom.

      Presentation software packages like PowerPoint and OO Impress are easily incorporated into networked classrooms. Teachers can use presentation software to add multimedia content to lessons. Students use these software tools as "virtual poster boards" for class reports. Some things just don't change and telling everyone what you know is still a big part of learning. Creating the presentation is still what brings it all together for many students.

      Desktop publishing is an important use of PC's in today's schools. From one page flyers to student run newspapers, PC's make it happen. This is an area where computer use has acted as an equalizer in that everyone can now publish their ideas.

    3. Analysis - Here's an area where computers have changed education (or should...). With spreadsheets and graphing tools now on every PC, students have the power to ask and answer "what if" questions and to make ready comparisons of data. Anyone who has used a spreadsheet to investigate something as simple as the costs of a trip to Disneyland will understand how useful these tools are in the classroom. Examples of good programming exist in things like the chart wizard in Excel and OO Calc. Preview buttons and updated wysiwyg windows make it easy for students to interact with the software and make choices. They may be using a wizard but they are still in control of what's going on.

    4. Creativity - Some of our most empowered users of technology are art and music students. Our art teachers were quick to see the potential in computers. PC's are seen as creative tools by our students after taking PC art classes where before they were only seen as productivity tools.

    2. It wastes too much time. Children who don't know basic math facts (memorized, not computed) are at a disadvantage when they are learning higher level math. I'm not talking about calculus here; they are at a disadvantage learning algebra. While other students are distributing, students who don't know math facts can't keep up with the arithmetic. Kids that might be much better at understanding concepts take much longer to solve the same problems because they didn't take a few weeks to memorize a few facts.
    3. It's not helpful in life. When you're shopping after Christmas and need to figure out what something that is 30% off will cost, it's good to know that 30% is about 1/3 and how to divide by 3 in your head. Someone who didn't know these facts could still come up with the answer (maybe even a better answer), but not without some time consuming mental games. I suppose you could say that people should always carry calculators to do these things, but we don't. Sometimes we even do math in the car "how many more hours to get home?" If you know some math facts it's safer than using a calculator or relying on formulas and your addition skills.

    S: That's not the right way.
    T: So what? It works for playing scales.
    S: But it doesn't work for real music. It just works for scales.[sometimes you have to search for this one]
    T: Exactly. And that's why you have to show all of your work in algebra. It's not the fastest way to do these simple little problems that no one cares much about, but it's the best way to learn to solve the more complex equations that you'll see later this year and next year.

    At this point enough of the class "get it" that it's not a battle to show your work. Instead you work on the 1-2 hold outs and the person who was sick that day. Later in class, 1-2 students will point out the harder problem that you wrote on the board and say they figured it out in their head. Congratulate them and ask them how long it took. Maybe point them toward how it is related to the first easier problem.

    Many thanks to TheWanderingHermit for the well written responces to the "I don't need to show my work" posts.

  19. I've taught teachers by Bora+Horza+Gobuchol · · Score: 2, Insightful

    Three years ago I was responsible for teaching a great many of the public school teachers in Calgary basic computer skills. The Calgary Board of Education decided to make said skills required for their staff, and contracted the training company I was working for at the time to teach classes on basic use of the computer, Internet, scanners, etc.

    The experience led me to the conclusion that it is not the presence of computers that makes for a poor classroom experience - it is the ability of the teacher. Many of those I taught actually resisted learning something new, either being techno-phobic or holding the attitude that they were being "forced to learn" by the board. Many had a hard time learning anything at all. The overall attitude I got from many was that they had learned everything they needed to know in teacher's college 10, 20, 30 years ago and through their own experience - and how dare this young whippersnapper try to show them something new.

    The reality is that the vast majority of students in any classroom, except for those in low-income areas, will already have access to a computer at home. They will have grown up with one, unlike their teacher, and likely know how to use it better. My advice would be to throw off the censoring software and let them at it. Let the students come up with new and interesting ways to fulfill their assignments with these tools. The same skill is likely beyond the abilities or comprehension of their teacher.

    The problem is, not everyone is making more than the minimum wage. The more money people make, the more those people can spend and the stronger our economic cycles will be.

    This is an invalid statement. The more money people make (through an artificial minimum set by the government) the more labor costs. The more labor costs, the more things cost (inflation). The more things cost the less likely people can afford to buy things. Increasing the minimum wage DECREASES the amount of things people can buy. Price controls and wage controls just don't work, no matter how many times they are tried or what they are called.

    If I'm a business and can "get away with" paying people $5.15 an hour, I might think I'm doing great. But in reality, those people are going to be poor consumers of my products/services. A rising tide lifts all boats.

    Under your theory then lets raise the minimum wage to 1 million dollars a year. In that way everybody will be a millionaire. Talk about raising all boats.

    Oh wait, but then a value meal at the local McDonald's will cost $480 (1 hour of work at $1mil/year), and then you'll be complaining about inflation eating away at peoples savings.

    The cost of goods has to be related to the cost of the labor to produce those goods. If you raise labor costs (by setting an artificial wage floor) you raise the costs of goods created by that labor. Indexing the minimum wage to inflation will cause one of two things: a) runaway inflation or b) labor to move off-shore locations where there aren't minimum wage laws.

    So in the effect of trying to do good things and "raising all boats" you've caused everybody to drown. I recommend you read a good book on basic economics theory Basic Economics: A Citizen's Guide to the Economy by Thomas Sowell. It should be required reading to vote in this country.
