Comment: What about body fat % (Score 2) 409 409

In the age of cheap body fat % measuring devices, why not make body fat % the standard? I'm tall and borderline overweight according to BMI, but I have about 14% body fat percentage. It's much easier to compare across body types with that metric than BMI. Yet I've never had a doctor record my body fat %, only height and weight.

Good technology use is subtle. You mention whiteboards. This is a perfect example of good technology use. No chalk dust and in most cases the ink is more visible. Simple technologies like recording lectures is another example. We've had cheap video recording for a very long time. Now we have cheap delivery methods of those recordings (youtube). Maybe one day we'll reach the point where someone can do their calculus homework on a pressure-sensitive tablet and have a computer recognize where they made the mistake and explain why it's wrong.

A perfect example of where technology goes wrong is the Pearson mylab products. The technology is not subtle and not flexible. People spend a lot of time screwing around with inputting equations and other issues that don't help with learning. You don't spend time learning, you spend time making the software happy.

Comment: Dice data mining (Score 4, Interesting) 125 125

I have no doubt the submitter is serious, but I think the reality is Dice is just data mining with this post. They want to hear feedback to make money on their main product. There were far fewer of these "I have X skills and need a job" posts pre-dice purchase.

Maybe this tells us more about intelligence tests than anything. IQ has mostly been dismissed as an end all measure. We now know we can measure a persons intelligence a number of ways. IQ may have been a measure of a very specific type of intelligence, but had little correlation with one's life happiness.

I agree in principle, but the reality is a huge number of reviewers don't really understand the research paper they're reviewing. They are more concerned with things like "no previous research has been done" vs "little previous research has been done" and independence assumptions.
