The matter is by no means settled. Before 1992 most studies concluded that people read slower, less accurately and less comprehensively on screens than on paper. Studies published since the early 1990s, however, have produced more inconsistent results: a slight majority has confirmed earlier conclusions, but almost as many have found few significant differences in reading speed or comprehension between paper and screens. And recent surveys suggest that although most people still prefer paper—especially when reading intensively—attitudes are changing as tablets and e-reading technology improve and reading digital books for facts and fun becomes more common.

Compared with paper, screens may also drain more of our mental resources while we are reading and make it a little harder to remember what we read when we are done. A parallel line of research focuses on people's attitudes toward different kinds of media. Whether they realize it or not, many people approach computers and tablets with a state of mind less conducive to learning than the one they bring to paper.

Both anecdotally and in published studies, people report that when trying to locate a particular piece of written information they often remember where in the text it appeared. We might recall that we passed the red farmhouse near the start of the trail before we started climbing uphill through the forest; in a similar way, we remember that we read about Mr. Darcy rebuffing Elizabeth Bennett on the bottom of the left-hand page in one of the earlier chapters.

Whyville , What does it take to build a sustainable, green energy community? 8th Graders are showing us how using WhyPower, an interactive learning game within the largest interactive learning world, WhyVille. Here is an interactive game. http://www.poweracrosstexas.org/projects/whypower-interactive-game Energy Game:  WHYPOWER Whyville is a thriving community with its own economy, newspaper, government and much more.  It now has its own power grid!  As part of the WhyCareers program, we are “electrifying” Whyville with a power grid that uses traditional and renewable energy sources.  Students will manage the power grid to select the right mix of coal, natural gas, nuclear, hydroelectric, solar and wind energy. They will build homes in Whyville!  They will observe and measure power use in Whyville, and form good energy behaviors and habits. Finally, they will explore the math, science and career topics related to energy.  Just like in real life, success in Whyville is not pre-programmed!  Students skill, initiative, creativity and teamwork determines the rewards they receive and the “virtual money” they earn in WhyPower. Whyville. Run a city using energy reources.
