Our reality in a classroom (was: Why do students buy (cheap) calculators?) Message #13 Posted by Vieira, Luiz C. (Brazil) on 5 June 2004, 9:32 p.m., in response to message #12 by Cameron
Hello, Cameron;
your assumptions are perfectly clear for me and I agree with you and your analysis. If you read the post (in other thread) I refer to in my prior post (this thread), you'll see that part of what you wrote I pointed out, and you have gone deeper and faster, while I simply pointed them (some) out. I'll write some stuff here that's mostly based on my own observations and conclusions based in facts I saw and read about, so I'd invite those who do not agree with to expose their own view. Mine is not intended to be final, I may fail in my conclusions.
About calculators in Brazil and other countries. I teach classes at the local University and I'll tell you that teaching today is far from teaching at the time I was a student. I'm 42 Y.O., and I firstly saw a personal computer when I was about 20 as well, but I guess my "20's" are different of yours in terms of absolute calendar: it was in 1982/1983. In Brazil , at least in Petrópolis (Rio de Janeiro) we did not have a computer lab at the university till 1986, if I am not wrong. 8 PC XT running D.O.S. 3.3... And I remember that my HP41C with one memory module was still something to be proudly shown!
At that time, a teacher's word was enough to make a complete class to be in silence. Today, there's always a bargain involved. If you do not offer what they (supposedly know what they) want, you, as a teacher, are excluded. No place for a teacher inside the classroom that are not willing to transform a classroom into something beyond knowledge, communication, interesting subjects and interesting exposition. And we must survive to this with dignity, because if you "lower your shields", they (students) will also reach you in a demonstration of weakness. Sorry, this is not the subject.
Now I teach at the local university that's not the one I was graduated, and the "reality" is also different. Here we have two computer labs running LINUX (RedHat distribution) and MS Windows XP® in both of them. 28 computers total count, all 800MHz CPU with 128 MBytes RAM, 20GBytes HD. And no computer in any classroom. The classrooms are for plain classes, only. And I'd not be reasonable enough getting all students to the labs anytime I want them to perform computations. That's when I tell them that they'd better buying their calculators (a suggestion, not an imposition), but except for those attending financial related classes, I suggest them to buy the best Scientific calculator they can afford buying. Close to Araguari there's another town, Uberlândia, and their reality is somehow different: many universities, many different courses, many social realities as well. I know many students have their HP12C, PDA's, HP48GII, HP49G and other personal computing devices.
But in all cases, I can tell you that they are not conscious about what you mentioned: all the advantages of a portable, robust calculating device. For the (young) student though, the calculator is simply a stop-gap until "cheating" is no longer an issue.
Here it's not different, but while some computing gadgets are easily found and easy to buy in some places, final prices in here (and other countries) make some of these gadgets a "wish" instead of a possibility of acquisition. They are sold here, of course, but not necessarily to those who'd use them as computing-aid devices. There's still a "tech-appeal" here that turns these gadgets into some sort of "pheromone" that non-tech guys like to show... off. And this is market, sales... unfortunately.
Maybe it's a bit off-topic, but some background helps understanding other "point of view".
Cheers.
Luiz (Brazil)
