Most teenagers use social-media sites and parents are wise to it, "friending" their kids and monitoring which sites they visit at an increased rate, according to a study presented at an educators conference today.

Seventy-six percent of teens are on social-media sites, with most -- 93 percent -- of them on Facebook, according to the Pew Internet study that examined the behavior of teens online.

And the usage increases with age -- a sign that parents are sticking tight to a rule that only teens 13-years-old and up can go on social-media sites, something such sites have been dinged for failing to police in the past.

I'm at a little bit of a loss for words when it comes to the teen sexting phenomenon, and the statistics I see don't seem to give me a clear understanding of the issue.

Is sexting a socially accepted activity among kids, or is there a social stigma to it? Do 1 in 5 kids really do it? And is this more of a middle school or a high school issue?

After stumbling across the transcript of a 2009 teen focus group on sexting, I was even more convinced that even among kids there's not really a consensus.

It's really hard to be a parent and try to relate to what childhood is like for my kids. I know what it was like to be a tween and teen back in the 20th century, not what it's like today. 

A deadly summertime car wreck is a parent's worst nightmare.

It’s the perfect time of year to apply a little overdose of parental monitoring – and keeps those kids safe during those sizzling summer months!

We're smack in the middle of the 100 deadliest driving days for teens aged 15 to 19, which fall between Memorial Day and Labor Day, according to AAA. Car wrecks are the leading cause of death for U.S. teens, and more teens are killed on the road during summer than any other time of year.

It's easy to focus on the desktop or laptop computer in our child's life and forget that the Internet is just as accessible from the cell phone hidden in their pocket. Previously we mentioned 4 reasons to monitor your child´s cell phone.  Internet dangers don't become less prevalent or less serious because our kids are on a phone instead of a computer.

This week, take some time to evaluate whether you're allowing things on the smartphone that you wouldn't on the Internet, or vice versa. It's the same Internet, and the same rules should apply no matter how your child is accessing it.

If you've got a teenager with a phone, do you talk about how they're using it to go online? If you are guilty of monitoring computer usage more than phone usage, you're not alone.

We all know that texting while driving is dangerous – statistics agree that it's even riskier than driving drunk. But even if your child isn't even close to receiving his or her license, you're not off the hook just yet. Texting also presents a potentially fatal distraction while simply crossing the street.

In a recent study published by the University of Alabama, 10- and 11-year-olds were observed walking across the street in a simulated environment, several times while using their phones and several times while not using their phones. Researchers found that children using a cell phone took 20% longer to cross the road, were 20% less likely to look both ways, and were twice as likely to be hit by a car. Your kids safety may be affected by using their phones even when they are walking!

Aside from modeling good behavior by never using your own phone while driving, or having frequent conversations with your kids about the dangers of texting and driving, you can also use a mobile app like iZup to curb the temptation for your teen to text and drive and keep your kids safe.

The name iZup literally means “eyes up,” meaning that it keeps your teens from looking down at their phones when their focus needs to be on the road. iZup is compatible with Blackberry and Android, and it works using the phone's GPS.

 Once the phone reaches 5 MPH (or another speed you select when you set up your account,) the app will automatically hold all incoming texts and calls. No outgoing texts or calls can be made, either, except for 911 or other numbers you authorize when you set up your account. It's a great app to enable parental controls in the car and help keep your kids safer

 Currently, iZup is available for a subscription of $2.95 per month or $19.95 per year. You can put iZup on up to 5 phones with a family monthly subscription of $5.95 per month ($59.95 per year.)

If you've seen one of your kids' text messages recently, you may have been concerned about what all that text-speak is doing to this generation's spelling, vocabulary, grammar, and general command of the English language. Do you need to?

It's true that text-speak is disconcerting to grammar purists, who shudder at the question “where u at?” or shortening entire phrases like “in my opinion” to “IMO.” Some English teachers also say they see too much informal language and too little structure in their student's writing, which could be attributed to texting and sexting.

However, studies like the one at the University of Toronto suggest that today's generation doesn't really have a problem switching between writing in “textese” to their friends and in more academic language in English class.

Do you ever wonder about the impact that excessive technology might have on us as a society? Probably no one is more concerned than parents of teenagers, because teens are much more likely to text, be sexting, play games online, and use social networking all the time.

Though scientists are still forming conclusions about the effects of a digital lifestyle, one new study suggests that frequent texting may lead to shallow patterns of thought and behavior in young people.

A kids safety nightmare for all parties involved: Nineteen-year-old Kaitlyn Dunaway from California was sentenced this week to five days in jail, 115 days home confinement, and three years probation. Her crime? Running over a mother and her 2-year-old daughter as they crossed a crosswalk while Kaitlyn was texting and driving.

The mother, 42-year-old Ling Murray, was critically injured and spent the next several months in a rehabilitation facility. The 2-year-old daughter, Calli, was killed.

Teen and kids safety alert: Alexis Summers, age 17, was killed in a fatal car crash as she texted at the wheel while driving early in November. What makes her death particularly poignant is the fact that she died only 8 hours after her home state of Pennsylvania passed a bill to make texting while driving illegal.

On the way home from visiting her boyfriend, Alexis's car left the road, hit a tree, spun around, and collided with the tree a second time. She was pronounced dead at the scene.

Highlighting kids safety laws surrounding texting and driving:

When a state makes it illegal to text while driving, most of us breathe a sigh of relief that the roads are going to be that much safer from now on. But research actually suggests that this may be the opposite of reality, especially for teen drivers.

Texting or for some, sexting is how most kids communicate – it's easy, it's fast, it's convenient, and teens always have their phones with them – but sometimes it can go too far. You've heard of cyberbullying, but have you heard of cyberstalking and text harassment?

Statistics from the U.S. Justice Department reported in 2006 that 23% of stalkers used texting and email to harass their targets. And the kicker is that with texting the victim has to pay for it, sometimes as much as 15 cents a text. Ask your teen if they or their friends have ever been in a relationship where their significant other constantly texted them, almost to the point of harassment. You might be surprised.
