Hello folks,
I have just landed a very exciting job as a math & science teacher in an alternativetype school where teachers are allowed  and even encouraged  to seek new ways of teaching their pupils besides classic "chalkboard lecturing". My first thought was of course: "Hell yeah, I'll FreeBASIC the $%#@ out of this place!".
So, I'd like to know if anyone here have any practical experience with programming as a teaching tool? I have a lot of ideas I'd like to try out but currently very limited experience.
Cheers,
Michael

Re: Using FreeBASIC in the classroom?
Sounds like an interesting job.
Hobby electronics and computer programming motivated me to teach myself some math so I think they go well together.
Just a quick google on the topic,
https://www.theedublogger.com/2014/02/0 ... eachmath/
Now that I think about it, there are a ton of ways that coding could and should be brought into the math classroom on a daily basis.
For example:
output and printing to screen teaches concepts like Cartesian plotting, graphing functions and conics
using the logic of loops, if, else, etc to teach principals of proofs
number sense – integers, floating/rounding, and how using the wrong data type effects programming
writing simple programs to solve the quadratic formula, the midpoint theorem, and more – automating the wrote memorization processes we’ve been drilling and killing for years

Re: Using FreeBASIC in the classroom?
I could offer a curve sketching program for the command line and a flow chart editor I wrote some time ago.

No, my thoughts:
If I look at a list of physics topics like on http://www.physicsclassroom.com/Class, I see some topics where code could be used to visualise concepts. Mostly mechanics (motion, acceleration, gravity, vectors, mass, forces, etc.). But for other topics (like electricity, light, waves), I don't see how computer code can help to make the topic more clear and fun. Anything can be demonstrated by code of course, but if the code gets too complicated, you will be teaching mostly programming.

Yes, I have a lot. Numerical and symbolic calculations help to introduce difficult concepts
fast and on a practical level. But don't start with programing. Use Maxima (with wxMaxima GUI).
It is free and exists on Android. You can teach programming with Maxima (or FB if you wish) later on.
Good luck
Re: Using FreeBASIC in the classroom?
I was at sea my working life, but I did have a break in the nineties teaching secondary maths in London.
This was the time when rote learning (Tables) went out of fashion (for a while)
Fancy new ideas (calculators, different ways to do long division, e,t.c. sprang up)
This left thousands of children mathematically illiterate.
Left them terrified of anything numerical.
Teachers were secretly drilling the kids their tables (sometimes only up to X 10)
Basic, Pascal, were designed for teaching.
FreeBASIC would be ideal.
But maths and freebasic should progress together IMHO.
For curve sketching for example, the ability to map from one range to another (coordinate geometry) should be more important than the actual freebasic code.
My humble teaching trial:

Code: Select all
function map(a as double,b as double,x as double,c as double,d as double) as double
dim as double y
'Required function result is
'get y so that:
'as x ranges between a and b then y ranges between c and d
'This is equivalent to coordinate points on a line
' (a,c) (x,y) (b,d)
'gradient of a line = difference in y/difference in x  (dy/dx)
'gradients:
'first part of line = whole line (same gradient of course)
'(yc)/(xa) = (dc)/(ba)
'so (yc)=(xa)*(dc)/(ba)
'and therefore
y=(xa)*(dc)/(ba) + c
function= y
end function
'test mappings
screen 19
dim as double pi=4*atn(1)
dim as double angle,sinangle
'required to plot
'sin(angle) between pi and pi
for horiz as long=0 to 800
angle=map(0,800,horiz,pi,pi)
sinangle=map(1,1,sin(angle),600,0) 'sine range is 1 to 1
pset(horiz,sinangle)

Re: Using FreeBASIC in the classroom?
I would recommend to teach something about the daisyworld:
https://serc.carleton.edu/integrate/tea ... unit4.html
It's a perfect topic for a freebasic simulation.

Re: Using FreeBASIC in the classroom?
Public key cryptography.
I can hear the thuds from here as folk fall of their chairs laughing their heads off.
"I also believe that crypto is perceived as hard because cryptographers haven't done a good job of teaching it."  JeanPhilippe Aumasson, coauthor of the Blake SHA3 finalist.
So, we all find crypto hard then. Catch them young and do a good job of teaching it. The principle of public key cryptography is simple, unlike symmetric key encryption. Youngsters were giving their smart 'phones serious workouts whilst the majority of us were still scratching our heads. Youngsters will love it and have fun sending each other 'secret messages', using small keys. FreeBASIC can be used to develop them and larger keys. There is some maths and probability but it is not 'heavy' or at least it need not be.
"What did you at school today, Jimmy?"
"We just started public key cryptography"
Father hesitates, not knowing what Jimmy is talking about.
"I didn't do that when I was at school"
First job interview.
"Do you know anything about cryptography?"
"Haven't done that much but we did public key cryptography when I was younger"
"You did WHAT?"
Get the picture.
By the time they are ready to go out 'into the world' cryptography will not be the slightest bit intimidating to them and the Internet will be a much safer place than it is today because of that. Some of them may enjoy it enough to go into further study and that will also make the Internet a much safer place than it is now.
There is a lot of material on the World Wide Wait doing a really good job of explaining public key cryptography. Here is just one that I found very quickly: What is the Smallest RSA Private
Key
Stopped laughing yet? <smile>
Added: Most of you will know this but some may not. A lot of crypto material refers to an attacker as 'she' or Eve. It is short for Public key cryptography.

Re: Using FreeBASIC in the classroom?
I once subscribed to Quantum Magazine which had a column by Dr. Mu called Cowculations, "the column devoted to problems best solved with a computer algorithm.", the problems were quite amusing, sadly the magazine died in 2001.
you can download the pdf files but they are about 77MB in size, the last column by Dr.Mu was published in Volume 9 No. 6
why do I mention this?
the articles were interesting and humorous and challenging and perhaps you could pose to your students problems of that nature.

True, but not a problem imho. We have four basic interacting forces in the universe: Weak and strong nuclear forces, which we will only be touching, electromagnetism and gravity. Setting up an electromagnetic experiment is very straight forward, all you need is some copper wire and a few permanent magnets and you're good. No need to use coding here. With gravity it's the opposite. Setting up a gravitational interaction experiment is not possible  apart from letting various objects drop to the ground. Here we can use code to show the pupils that the force that makes thing fall off the table is the same that keeps the planets in place around the sun. They can experiment by creating their own solar systems, and destroy them again. Here coding is the perfect tool.

Thanks everyone for your replies, you've given me some tracks to follow.

@deltarho
Thank you.
The smallest key was something that occasionally flashed across my thought screen.
Now I know.

Verrrrry interesting.
Thank you.
Both good.
