As a homeschooling family, my wife and I are very involved in our children's education and since we're both a couple of nerds, much of our children's education is done on the computer.

When I took Calculus in college, my Professor would give us substantial partial credit for test problems that we got wrong for minor arithmetic errors, and rightfully so, too. Sometimes even simple-sounding problems resulted in a full page, or more, of calculations. Simply changing a -1 to a +1 early on in a problem could be completely devastating.

A couple of weeks ago, I wrote an article about a digital and analog circuit simulator called ksimus. One of my readers asked what the difference was between ksimus and ktechlab so I thought I'd take a look at ktechlab.

I've written quite a bit about using Linux to help educate people. In the past, I've discussed using Linux to teach astronomy, programming and computer logic design. So today, I'm writing about using the KDE Interactive Geometry (Kig) program to teach mathematics. Kig allows you to use various tools to diagram and demonstrate different mathematical concepts.

I took a Computer Logic Design class in college, so when I stumbled upon the Ksimus Circuit Simulator, I was intrigued. At the risk of waxing nostalgic, I remember what it was like to build circuits in school. We'd spend hours the night before the lab designing our circuit, being careful to list each interconnection. We had to keep track of which pin numbers on each chip were to be connected.

As a parent of three young boys, I often think about what it's going to take to be competitive in the job market of the future. Obviously, they'll need solid reading, writing, math and science skills, with history, literature and art thrown in to make them well-rounded. Being a computer nerd myself, I recognize the value of even basic computer skills.

Everywhere you turn there are "brain training" games that claim to help you "lower your brain age" or "boost your brain power" and other such marketing hyperbole. Much like saying a certain breakfast cereal is "more satisfying" than other cereals, these claims are basically meaningless.

With Labour Day past, we back in the season of slide shows -- million of them daily in both academia and business. For over a decade now, slide shows have become an accepted prop for public speaking, regardless of whether they are useful or well-designed, and the trend shows no sign of slowing. You can, of course, just acquiesce and accept that as soon as you click to the first slide, most of your audience will sigh deeply and sit back low in their chairs. But, if you really want to make slide shows work for you, you'll think before opening up the Impress wizard.

I, as well as my 4 year old son, have always had an interest in Astronomy. My son puts planet puzzles together and looks at picture books. I'm proud to say that he can name all the planets in order, and astonished to realize that he knows that Pluto isn't considered a planet anymore. I've read books on Astronomy; I've been to planetariums and observatories.

Brain training comes to Linux with The Amazing Brain Train from Grubby Games.

One of the biggest arguments used against Linux in grade school level education is that we aren't teaching kids to use the applications they'll use in the "real world". As the Technology Director for a K-12 school district, I've heard that argument many times. After all these years, I still don't buy it.

As Products Editor and Newsletter Editor here at Linux Journal, I come across many computer books. Despite our era of 'get it on the 'Net' and perverse industry consolidation, I am continually astounded by the variety and quality of books, on both real and virtual paper, to which we now have access.
