About IntMath Projects

(a) Newsletter

The IntMath Newsletter goes out to almost 8000 subscribers around twice per month. The readers range from grade 8 (who are struggling with fractions, indices and decimals), through high school algebra and trigonometry students, calculus and beyond. The "beyond" is quite a large group of retirees who enjoy learning math for pleasure.

So the challenge is to pick topics that will be of interest to everyone.


My main site attracts around a million page views per month. It's called "Interactive Mathematics", but most people keep coming back (they say) because of the "clear and easy to understand explanations".

The exploratory interactive materials use Flash, Scientific Notebook and LiveMath. Recently I've been adding SVG graphs and LaTeX, which allows more flexibility.

The most popular pages are:

Derivatives of Sine and Cosine

Basic Algebra
Graphs of Sine and Cosine
Graphs of Inverse Trigonometric Functions

Solving Differential Equations

(c) squareCircleZ

The blog covers a wide range of math topics (and occasionally other things that interest me). The most popular articles have been the "how to" type (like How to draw y^2 = x – 2?) and ones that have a human connotation (where we see how math is used in the "real world")

(d) Notation

I have a special interest in math notation and how it unnecessarily adds to students' confusion.

(e) Getting Math on the Web

I'm also interested in the extra load there is when learners are trying to discuss math problems on the Web. Most will just type their algebra or matrices in a linear way which is difficult for them and almost impossible for the reader to understand.

ASCIIMathML and ASCIIsvg have been the easiest methods I've come across to publish math on the Web.

murray-bourne2.jpgMurray Bourne:
I was a teacher in secondary schools in Australia for some years. I was in Broken Hill (outback Australia) and then Grafton (northern NSW).
I then moved to Japan where I taught mathematics (in English) for 4 years in an interesting program that prepared Japanese students for college courses in the USA. The students would spend one year improving their English, followed by one year doing a typical freshman program, then off they would go to small mid-West colleges. I also taught English while in Japan.
On returning to Australia, I taught in TAFE (Technical and Further Education), Bond University and Griffith University.
I then moved to Singapore where I taught engineering mathematics in a polytechnic. I am now doing staff training in the same institution.
