"If we teach today as we taught yesterday, we rob our children of tomorrow", this quote was said by John Dewey. I think what John Dewey was trying to say, is that if we kept teaching new generations the same way we taught kids say 50 years ago, our knowledge will never expand or grow. Every year it seems like people are coming up with all these new inventions, new cures for so many different diseases and sicknesses and technology, why is that you think? I think it's because technology is growing so dramatically, researchers and scientists have been able to do so much more with all this new technology! Kids now a days have such a different experience in the classroom from when I was in elementary school. If you went around to look into every classroom throughout a school building you would see a Smart Board in practically every room. Just this is such an improvement from Over Heads that my teachers had to use when I were their ages. There's so many different things they can do now with them. It's great that out knowledge is expanding so much. The kids growing up in this generation  are going to have such a great education when they finish high school. Every few years the way teachers teach math, science, English and every other subject change. They find what works and what doesn't works and fix it up, or even change it completely if they find a better way to teach the subject.
