A Fort Worth teacher's note sent home with students is going viral.

It notifies parents she won't be giving homework to her students unless its classwork they didn't finish during the day.

She goes on to say research hasn't proven homework is effective, but spending family time has been proven to correlate with student success.

Studies have been done, but so far there hasn't been a definitive answer if daily homework truly works.

Teachers and psychologists say homework helps students retain information.

But many of your kids are also spending too much time hitting the books at home, and it's causing a lot of stress.

Just because the day's over doesn't mean the learning is. 

Jaylynne Edlebeck is a student at FGCU. "We would do math homework for about two hours per day," she said of her time in high school.

Some students are hitting the books just as hard outside of school.

Teresa Pease watched as her fifth-grade granddaughter hunched over her school books until it was time for bed.

Pease says, "She was totally stressed, and it interfered with her sleeping."

Is the stress worth the education? Early Learning Director Andy Spaulding and the American Psychological Association say yes - in moderation.

"If you're doing 100 math problems, I probably got it after 20 problems, and now I'm just doing busy work," Spaulding said.

Age also determines the workload. The National Education Association recommends following the 10-minute rule. From first grade on, add 10 minutes of homework.

Spaulding pointed out that homework doesn't just help students.

"I totally think she's on the right track but without doing the homework, she's not getting the feedback she needs to really monitor where her kids are," he said.

A school psychologist said having more downtime after school can help decrease stress and increase sleep.

Also, if a student is doing a lot of homework and not being challenged or is really struggling with the homework, they can become disconnected when it's time to go back to school the next day.
