“Why the U.S. STEM Initiative Shouldn’t Ignore Computer Science,” is a fascinating “infographic,” (a pictorial presentation of statistics) from the New Jersey Institute of Technology. We’ve shortened the long web address to just tinyurl.com/USlag. The chart shows that 150,000 new computing jobs will need to be filled every year for the next ten years. In five years, there will be three times as many computer science jobs as applicants, yet nine out of ten elementary and high schools offer no programming classes. Ironically, computer science is one of the top five highest paid college degrees. See the books below.
TheDoghouseDiaries.com is an odd one. Click “Archives” and “October 18″ to get “What Each Country Leads the World In,” a humorous look at leading exports and culture. Canada leads the world in “maple syrup and asteroid impacts.” For Russia, it’s “raspberries and nuclear warheads.”
“Nova Elements,” a free iPad app, takes the periodic table off the wall into an atomic sandbox, where you can play with particles to create your own copper, gold or any one of the other 118 elements. You can then combine them to make molecules. It’s been downloaded over 570,000 times.
Lynda.com is our favorite site for training videos and has hundreds of courses on everything from using Amazon.com to conquering Photoshop. But “Mindsy” is a new site with courses on a wider range of topics, such as using Gmail to become more productive, how to make a video game, and – in case it’s just all too much for you — meditation.
A new start-up has drawn $4 million from investors to fuel an online tutoring service called InstaEdu.com. So far they claim to have 3000 tutors on hand. It costs $24 an hour to get tutored, and the tutors get to keep $20 of that, an unusually generous split. Tutors can work as little as 20 minutes a month. You have to be 18 and have some tutoring experience to apply. Students choose the tutors they wish by reading online profiles. We noticed that some are graduates from prestigious colleges. (Kind of a sign of the times.)
The web site Visual.ly/100-Years-Change compares 1913 to 2013 in fashion, sports, tech, population, and every day life. Average annual income was $800 then; now it’s $26,000. Population was 97 million, versus 312 million currently. Two percent had a bachelor’s degree back then, now t’s 28 percent. (Practically every cashier at our local supermarket has a bachelor’s degree.) A big problem with the numbers for prices and incomes is that they are not adjusted for inflation. Another site, MeasuringWorth.com, deals with this problem and tries to establish a comparison using inflation, though some comparisons can’t be adjusted that way because of changes in manufacturing and transportation. One approach is looking at purchasing power measured against the consumer price index. Using that […]
Boundless.com is being sued by textbook publishers for offering cut-rate and cut-down versions online. They cover 21 subjects and all the books are $20, which is quite a bargain compared to $100-200 for many printed textbooks. Here’s how it works: Instead of an actual textbook, Boundless summarizes all of the key information, chapter by chapter into a condensed version about 90 percent shorter. You’ll miss the author’s style, but you’ll get what you need to know, complete with flashcards, quizzes, and reminders. Their own research shows Boundless users study far less than other students and get better results.
