Python for Math Teachers [ID:101]

a series of video-tutorials by Kirby Urner

These videos take a "math through programming" approach, meaning we're using Python to develop a stronger grasp of mathematical concepts.

Video Tutorials

1. Getting Started

Let's use IDLE to define a few functions, including the Euclid's Algorithm for the GCD. Atop the GCD we'll build other functions for listing totatives of N (positives relatively prime to N) and the totient of N (the number of said totatives). We're using the default Python shell to introduce new math ideas (math through programming).

2. Looking Ahead

Let's download some source code over the Internet and take a look at a Python class definition. This class defines integer instances that operate modulo 23. This module might be used to discuss some basic concepts in group theory. We'll come back to these ideas when we look at RSA, the public key cryptography algorithm.

3. Subclassing for Beginners

Let's define a simple Dog class and show how we make instances (dogs). Then let's add a stomach attribute so our dogs can eat and poop (kids love scatology). It's a dog eat dog world! Then we refactor the code to show how Dog and Monkey classes might both inherit from the Animal class.

4. A First Look at RSA

Building on some ideas introduced earlier in this series, this easygoing lecture takes a somewhat rambling approach to a rather difficult math topic. This is background for math teachers intending to use Python as a vehicle for exploring math concepts interactively, in a hands-on setting.

5. Working with Stickworks

Here's a Python module you might want to use in your math classes. It works with VPython to provide simple vector graphics, as well as plotting capabilities. Students wouldn't just use the module, they'd study the source code to gain a stronger understanding of the math concepts involved (math through programming).

6. Chicago Pycon 2008

Overview regarding how to converge the mathematics and computer science curricula more successfully, with Python providing a bridge.

Showmedo is a peer-produced video-tutorials and screencasts site for free and open-source software (FOSS)- with the exception of some club videos, the large majority are free to watch and download.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for Kirby

Learning Paths

This series lies on the following learning-paths. Learning-paths are a new initiative at Showmedo, to start structuring our content better. You can find out more here.



Showmedo's development is fairly rapid and bugs will inevitably creep in. If you have any problems please drop us a line using the contact address below. Likewise, any suggestions for improvements to the site are gratefully received.
