1. Free resource: Study Tips from Cornell University
Suitable for: Students
Work smart! Many students are very inefficient when they study. Here are some good bits of advice.
See all the resources here: Cornell University Study Skills Resources
2. Have your say - how should math education be changed?
Suitable for: Students and teachers
Here's an interesting opportunity and something interesting to do over the up-coming summer break.
Elev8ted was "a site for students to upload 2 - 3 minute videos that:
- Inspire others to transform eduation
- Offer new choices for what education could be
- Propose specific actions you or others can take to improve education in your community"
So what are your ideas on how can we improve math education? Students, here's your chance!
Update: Unfortunately, the site no longer exists.
3. Free resource: Space Math @ NASA
Suitable for: Students and teachers
So how is math used in the "real world"? Here's an institution for whom math is vital - NASA. There are articles about the recent earthquakes, tsunami and nuclear disaster in Japan.
Do a search on "math" when you get there. You will find topics like: Black Hole Math | Earth Math | Image Scale Math | Lunar Math | Magnetic Math | Radiation Math | Solar Math | |
4. Derivative of square root of sine x by first principles
Suitable for: Students of calculus. Several readers asked how to differentiate trigonometric functions from first principles.
Here's how to find the derivative of √(sin x) from first principles. |
5. GeoGebra is part of Google Summer of Code 2011
Suitable for: Students
This is an interesting summer project - write some math-related software for Google! |
6. Lesson idea for order of operations
Suitable for: Teachers
Here's a motivating way for students to learn order of arithmetic operations. |
7. Final thought – enthusiasm
Charles Kingsley (1819-1875), English clergyman and novelist, had this to say about enthusiasm.
We act as though comfort and luxury were the chief requirements of life, when all that we need to make us really happy is something to be enthusiastic about. [Charles Kingsley]
Enthusiasm for life, and math, certainly makes me happy!
Until next time, enjoy whatever you learn.
