You’re probably not getting enough sleep, but you might not be as far off the mark as you think. Most sleep experts would offer that aiming for between seven to nine hours of snooze time a night is optimal for feeling refreshed and productive the next day. In a new report, however … researchers are closing in on what may just be that magic nightly number—and it’s not nine hours, or even eight as once believed… it’s seven hours of sleep.

The usual caveats apply, and these findings should be taken with a grain of salt. But the results are interesting—especially if you’re the kind of person who struggles with sluggishness throughout the day.

"The lowest mortality and morbidity is with seven hours," [says] Shawn Youngstedt, a professor in the College of Nursing and Health Innovation at Arizona State University Phoenix… "Eight hours or more has consistently been shown to be hazardous."

Intriguing new study on the optimal amount of sleep. But that grain of salt can’t be overstated given the wide variation of “chronotypes” and internal time.

This may be the greatest invention in the history of water balloons If you’ve ever had the pleasure of participating in a water balloon fight, you will concur that the most frustrating part of battle is reloading. You think you’ve got an uninflated balloon securely attached to the end of a garden hose, and then as soon as you turn on the water, *snap*, the balloon comes flying off. Or maybe you don’t even get that far — the balloon breaks as you’re stretching it on. Or you get it all filled up, and then you can’t tie it and it drops and breaks on the ground. Now some ambitious inventor has come up with a solution to all those problems: a device that lets you easily fill up 37 water balloons at once, and 100 in less than a minute.

Examining Knowledge Beliefs to Motivate Student Learning

4 Tips for Flipped Learning

As interest in flipped learning continues to grow, so does its adoption among the educational rank and file. By moving entry-level information outside the classroom — typically (but not exclusively) through self-paced, scored videos — teachers can reframe learning so that students spend more instructional time engaged in deeper discussions, hands-on applications and project-based learning. With a focus on more direct contact between teachers and students, greater application of basic concepts, and increased collaboration between learners, flipped learning provides yet another outlet for 21st century teaching.
No doubt, making this kind of change can be intimidating. Before teachers flip out, here are four tips to make the transition smoother — and more impactful…

Kindergartners’ Skills at School Entry: An Analysis of the ECLS-K 

Although most American children receive some pre-K child care and education, kindergarten still represents many children’s first exposure to formal schooling. Kindergarten supports children’s cognitive, social, and emotional skills, leading to rapid gains in knowledge during this first year of education. 
However, not all children enter kindergarten equally prepared to meet the challenges ahead of them. Researchers have found stark differences in kindergartners’ language, literacy, and math abilities as well as their social skills and behavioral approaches to learning. These areas are interdependent, and children who start kindergarten behind in math, reading, and attention-related skills risk being unable to catch up to their peers later on.
