Two hours after a service module’s oxygen tank explosion on Apollo 13, Commander James Lovell did calculations that helped put the ship back on course so that they could return back to Earth. They needed to establish the right course to use the Moon’s gravity to get back home. Check out the article on Gizmodo from November 2011.

and some other reasons students hate school.

Here are a few recommended children’s books that have math in them!

I love The Oatmeal and they have a funny little bit about what they think should have been taught in high school. I just posted the math for obvious reasons but you can check out the whole strip that covers all the subjects.

If you haven’t heard about Khan Academy, then you probably aren’t in the field of education. There has been tremendous criticism of Khan Academy by educators because it ultimately just lectures to students and many educators – at least the ones I keep up with – prefer having students approach math in a different way. Math is often seen as something that you learn and then practice. With more practice, you’re supposed to – with the traditional thought behind mathematics education – get better at math but I don’t think the point of math is to be able to memorize and practice problems over and over until you’ve mastered the skill. Although this can be one way people learn math, I don’t think they’ll truly understand it this way. Many other teachers really like Khan Academy because it does the lecturing for them. The program does have its benefits as it does allow students to work and learn at their own pace. Unfortunately, I’ve witnessed teachers just have their entire class watch a lesson in lieu of them teaching it, then pass out a worksheet for them to practice this new concept that they have just “learned.” While I may not be its biggest fan, I know Khan Academy does help some students. So for those of you that may get some benefit from it, check it out. Here’s a sample of what the videos are like:

An interesting question posed by Andrew Hacker at The New York Times a few days ago. You can read his opinion here.

Teachers love to force students to show their work. It’s not only a way to see if the student actually knows what they’re doing; it’s also a way to see exactly what a student doesn’t know. A wrong answer tells nothing about what the student knows or doesn’t know. Partial credit is usually the incentive for students to show their work – but you shouldn’t force students to show everything if the reaction is negative because you don’t want to have your students feel annoyed by you. As a teacher, you need to motivate, inspire, encourage, and enlighten. If you focus on the wrong parts of math, you’ll lose your students.

With that said, here’s a fun comic to remind us to lighten up sometimes. Don’t forget to use PEMDAS to get the correct answer!

R. Andrew Hicks, a Drexel University mathematics professor, has invented a new driver’s-side car mirror that allows a driver to see more that also eliminates the blind spot. How did he create this mirror? He used an algorithm that results in a surface ideally curved to capture a 45-degree view with minimal distortion. How long did it take him to come up with it? 10 years.
