Technology in my classroom - Channel 30 News

A local television news crew interviewed me and filmed my grade 6 math class for a news story on technology in the classroom.

Nice ! You could use Geogebra and some programming languages like Python to learn geometry and algebra.

You can reduce usage of python to simple "generator" so your student can experiment with something near mathematical language.

Like :
[i**2 for i in range(10)]
That can be translated as {x.x|x in R} (there is the overhead to learn Python syntax but they would have feedback instantly)

Or using Scilab etc.

It can also be used to let play maths games like Simons puzzles (http://www.chiark.greenend.org.uk/~sgtatham/puzzles/). Letting them discover how to be able to win every game then discussing about it.

There is so many possibilities.
And best of all, it can assist you in following each student individually taking into account weakness of each.(Maybe some tool needed here to track that)

Because every body has his own view of the same situation and technology can provide so many views of same object...

I do not understand why we don't learn to student how to make their model ! We learn to stick on teacher methodology. That's really bad . Teacher is here to give hints and provide knowledge and education, not to normalize people. I think technology is a great assistant here.

One of the major problem today is creativity and initiative. People think to know how to do things but they don't realize that hey miss a lot. How could they do ?

There is a big counter argument against computer : has they can provide quick results, we could be tempted to let him do bad job for us and avoid thinking what would lead to missed parts.

Example : Sum the 100 first integers.
That can be done in two ways at least :
Making the whole addition : 1+2+3+...+99+100. So, asking computer to do it.
Using a clever formula : 100/2+101

That means that teacher must workout on that, having in mind "will computer make student miss 'clever' path ?". If yes, don't use or tell student the solution and that they have to find a smarter way of doing that !

Asking for a smarter way is always entertaining because you feel really better when you find something that the teacher say "smart" :-)

Also, teaching a simple programming language can be a good benefit for student.
Most of the time, they learn to dissect a problem (if they are lucky and have good teachers) but they don't learn to model it or express it in another form. With language computer, they have some task to do :
Understanding the problem
Writing an algorithm
Backing the algorithm in computer language
Writing a human readable solution (understanding the result)

One simple problem would be :
How would you tell the computer to add 2 fraction given the two fraction has 4 numbers ?
And a possible answer :
let "a" as first numerator, "b" as first denominator, "c" as second numerator and "d" as second denominator.
The resulting denominator is "b*d" and the numerator would be "a*d+b*c".

Then you can ask, how would you tell a computer to reduce a fraction ?
Then they've to teach computer the methodology they use ;-) (as exercise for the reader).

Python is a really easy language because you don't have to declare variables and there is no curly braces.

Thanks for reading !

You have wireless! My school won't let me install a wireless router in my room.

Have you considered using Alice (alice.org)? You can incorporate some programming.
