We're starting with a new education law in the U.S.that could affect 55 million grade school students.
President Obama signed it into law yesterday after itgathered bipartisan support in Congress.
It's called the Every Student Succeeds Act and it replaces the controversial No Child LeftBehind law passed in 2002.
What will stay the same?
Mandatory testing and an emphasis on test scores to indicate group of students who arefailing.
What will change?
Power will return to states to decide what to do about schools with failing or underperformingstudents.
The president of the American Federation of Teachers called the new law a course correction,saying it moves toward a policy where states have more authority in educating children.

The words only decode for the person who's meant to read them.
It's this technique that sparked the debate at the highest levels of government, because thesame tech that helps the good guys also shields the bad.
And that tech is going mainstream.
At the center of it all, this guy.
We're out of food, honestly.
And the means to cook it?
Yes, how does that feel?
His name is Moxie Marlinspike.
It sounds made up because, well, it is.
He's a world renowned hacker and he's obsessed with your privacy.
He won't tell you where he's from or really anything about his past.
