En niet alleen dat, er blijkt ook maar weer eens uit hoe hersenloos gebruik van rekenmachientjes de ontwikkeling van een juist begrip in de weg staat.
Inderdaad. Als je op wat knopjes duwt dan krijg je het juiste antwoord (daarom niet altijd het antwoord wat je wil hebben), waarom zou je dan zelf gaan nadenken?
Beter eerst maar eens zonder rekenmachientje alle bewerkingen automatiseren.
http://americanhistory.si(...)hist/sj1.html#importHier een interview met Steve Jobs, dit interview werd afgenomen, vlak voordat Toy Story in de bioscoop kwam (tweede helft jaren 90?).
Wat hij hieronder zegt is een waarheid als een koe, het geeft te denken wanneer uitgerekend zo'n man benadrukt dat het de mensen zijn die het moeten doen en dat geen bestaande technologie de rol van de mens kan vervangen.
Hij heeft nog meer interessants over het onderwijs te zeggen.
The Role of Computers in Education
DM: Some people say that this new technology maybe a way to bypass that. Are you optimistic about that?
SJ: I absolutely don't believe that. As you've pointed out I've helped with more computers in more schools than anybody else in the world and I absolutely convinced that is by no means the most important thing. The most important thing is a person. A person who incites your curiosity and feeds your curiosity; and machines cannot do that in the same way that people can. The elements of discovery are all around you. You don't need a computer. Here - why does that fall? You know why? Nobody in the entire world knows why that falls. We can describe it pretty accurately but no one knows why. I don't need a computer to get a kid interested in that, to spend a week playing with gravity and trying to understand that and come up with reasons why.
DM: But you do need a person.
SJ: You need a person. Especially with computers the way they are now. Computers are very reactive but they're not proactive; they are not agents, if you will. They are very reactive. What children need is something more proactive. They need a guide. They don't need an assistant. I think we have all the material in the world to solve this problem; it's just being deployed in other places. I've been a very strong believer in that what we need to do in education is to go to the full voucher system. I know this isn't what the interview was supposed to be about but it is what I care about a great deal.
DM: This question was meant to be at the end and we're just getting to it now.
SJ: One of the things I feel is that, right now, if you ask who are the customers of education, the customers of education are the society at large, the employers who hire people, things like that. But ultimately I think the customers are the parents. Not even the students but the parents. The problem that we have in this country is that the customers went away. The customers stopped paying attention to their schools, for the most part. What happened was that mothers started working and they didn't have time to spend at PTA meetings and watching their kids' school. Schools became much more institutionalized and parents spent less and less and less time involved in their kids' education. What happens when a customer goes away and a monopoly gets control, which is what happened in our country, is that the service level almost always goes down. I remember seeing a bumper sticker when the telephone company was all one. I remember seeing a bumper sticker with the Bell Logo on it and it said "We don't care. We don't have to." And that's what a monopoly is. That's what IBM was in their day. And that's certainly what the public school system is. They don't have to care.
Let's go through some economics. The most expensive thing people buy in their lives is a house. The second most expensive thing is a car, usually, and an average car costs approximately twenty thousand dollars. And an average car lasts about eight years. Then you buy another one. Approximately two thousand dollars a year over an eight year period. Well, your child goes to school approximately eight years in K through 8. What does the State of California spent per pupil per year in a public school? About forty-four hundred dollars. Over twice as much as a car. It turns out that when you go to buy a car you have a lot of information available to you to make a choice and you have a lot of choices. General Motors, Ford, Chrysler, Toyota and Nissan. They are advertising to you like crazy. I can't get through a day without seeing five car ads. And they seem to be able to make these cars efficiently enough that they can afford to take some of my money and advertise to other people. So that everybody knows about all these cars and they keep getting better and better because there's a lot of competition.
DM: There's a warranty.
@Chris
Eigenlijk zouden ze de leerlingen die wortelformule (de eigenlijk naam) moeten laten afleiden. Niet elke keer opnieuw maar toch in ieder geval tijdens 1 toets. Zo moeilijk is het niet en je ziet dat het niet een of andere magische formule is maar dat je met een paar simpele algebraïsche bewerkingen zelf die formule kan reproduceren. Terwijl de leerlingen dit doen ontstaat hopelijk wat inzicht en ze leren tegelijkertijd kwadraatsplitsen wat met calculus voor een enkele toepassing weer gemakkelijk is.
