Can computers teach children? The very thought can make parents and teachers more than a tad uneasy. (Think of the Geico commercial where a cash strapped mother drops her child off at a nightmarish robot daycare,"because robots work for free.")

But there's mounting (if still mostly anecdotal) evidence that computers can actually help teachers focus on the very best kind of teaching, the kind that only humans can do. Jill Barshay of The Hechinger Report writes that Kindergarten students at a KIPP Academy in LA spend time at computers each day practicing their skills in math and reading. The school's principal sees the computers as liberating rather than dehumanizing. "By having half [the students] work on laptops in the classroom, a teacher is able to work intensely with the other 14 students."

As in industry, teachers can push the grunt work--lecturing or drill--off on technology and do the more human, personal work themselves. The Reasoning Mind math program for K-5 schools, which has received kudos from teachers, works on this principle.

So does the new practice of "flipping" lecture and homework. Students watch videos of lectures when they're at home and then actively apply the work--with the help of the teacher--when they're at school.

Early evidence from the KIPP school is encouraging: "95 percent of [its] Kindergarteners to score at or above the national average in math after the first year." It's too early to tell how much the computers had to do with that success, and some experts claim that Kindergarten is too early for such sustained exposure to computers.

Still, it may be that, if used well, computers will help humanize our schools.

The Massachusetts Governor’s Science, Technology, Engineering and Math (STEM) Council just released a video featuring people in cool jobs that require STEM skills. This is the first of a series of videos that the STEM Council will send to schools across the state.

The video features some pretty cool jobs. Check it out:

While we’re on the subject, have a look at some of the videos CTEq released last year to show kids how cool jobs that use STEM skills can be. Companies created these videos as part of a ground-breaking contest among CTEq members. SAS and Activision produced the winning videos:

"Teach them math, science and chess," proclaimed a headline in Saturday's New York Times. Just days before, The Washington Postran a story about a Chess grandmaster urging young school kids in Washington, DC to take up the game. in both pieces, chess gets props for teaching "discipline, analytical thinking, time management, focus and patience." The Times article comes close to promoting chess as part of the curriculum for every kid in K-12.

But it's not chess itself that should capture the attention of school reformers. It's what chess stands for: Long attention, perseverance, focus. Paul Tough recently called it "grit."

Grit is a critical element of success in school and life, and it can be fostered through any number of strategies. Opus 118, the Harlem youth orchestra Merryl Streep immortalized in Music of the Heart, is famous for the determination it teaches its young, mostly low income participants. So is the West Philadelphia Automotive Academy, where urban teens built an award-winning high-performance hybrid car.

In fact, programs like these combine inspiration and grit, catching students' interest and then giving them the stamina they need to succeed. That's a lesson that bears repeating.

American kids are dreaming big, and that’s good news. The bad news is that we’re not equipping them to realize those dreams.

A new Gallup poll finds that the entrepreneurial spirit is alive and well in America’s youth. Here are some of the more startling findings. Seventy-seven percent of students in grades 5 through 7 want to be their own bosses. Forty-five percent plan to start their own businesses. Forty-two percent say they will invent something that changes the world. (Yes, they can’t all be right—there can be only so many Steve Jobses and Bill Gateses—but you have to admire their spirit.)

Ninety one percent say they’re not afraid to take risks, even if they might fail, and 85 percent say they never give up. Gallup did not field this poll outside of the U.S., so we don’t know how students in other countries would have responded. Still, it’s tempting to see this poll as evidence that the uniquely American spirit of invention, enterprise and self-reliance is undimmed, even in these gloomy times.

But a stiff dose of reality may well overpower that youthful spirit. Altogether too few students are on a path to realize their dreams. The Gallup poll finds that fewer than 60 percent of students have a bank account, almost half don't learn about money or banking in school, and a scant five percent are interning with a local business.

The fact that so many kids have little or no exposure to money management or business may well stand in the way of their plans. But their anemic performance in subjects like math and science is at least as big a barrier to their success. Yet there, too, students are confident. An Intel survey in 2010 found that a whopping 85 percent of high school students think they're good at math and science. National and international tests tell a very different story, of course. There's a big difference between constructive confidence and blind bravado.

We have ample evidence that students' hopes are already being dashed. Overwhelming majorities think they'll finish college--91 percent by last count--but fewer than 7 in ten are even graduating from high school in four years. The graduation rates at two- and four-year colleges are much lower still.

Still, we should see our glass as half full. The Gallup poll shows that our students have pluck, that they want to make it on their own. We have a lot to work with, but if we don't get them more engaged in learning more challenging math and science, we'll squander our most precious national resource.

Gallup plans to keep giving this poll for the next 100 years. (How's that for pluck?) If our young people keep getting their hopes dashed, we may well see those poll numbers drop.

Would students of color do better in school if they were taught by teachers of color? A new study suggests as much. If we believe its findings, then we should worry about the scarcity of teachers of color in our country.

The study is limited. It focuses on a single (though admittedly very large) community college in California. That said, its findings are pretty dramatic. Here’s how the authors sum them up:

We find that the performance gap in terms of class dropout and pass rates between white and minority students falls by roughly one half when taught by a minority instructor.

They conclude that the effect is largest when students of color and their teachers have a similar racial or ethnic background. Why? The authors speculate that those students see their teachers as role models.

Can we apply these findings from a community college to K-12 schools? The study offers at least one reason to think so: “It is the young students who are most affected by the instructor’s minority status…. Young students are likely to be susceptible to role model effects, while older students are not.” Definitive? No. Suggestive? You bet.

The study gives us reason to worry about the numbers of minority teachers in US schools. People of color make up more than 38% of school enrollments but only 14% of the teaching force. What’s more, the ranks of minority teachers aren't growing nearly as fast as the minority student population.

For more than a decade, we've focused on the yawning achievement gaps between white students and students of color, but we haven't spent much time on the diversity of our teaching force. Are we missing at least part of the solution?

Yesterday, we wrote about new research suggesting that students of color do better in classes taught by teachers of the same or similar race. We lamented the fact that teachers of color seem to be in short supply. As luck would have it, a separate studyreleased yesterday attempts to explain their scarcity. Chalk it up to working conditions.

The new study’s authors, Richard Ingersoll and Henry May, have found that the problem isn’t getting teachers of color into schools. Efforts to recruit them into the teaching force have apparently paid off over the past two decades. The problem is keeping them in the teaching force. They are much more likely to leave teaching than white teachers are.

Ingersoll and May conclude that poor working conditions drive them out. They are more likely than white teachers to teach at schools that are hard to staff and are more likely to burn out as a result. What is their main beef? Many say they left because they lacked input into school decision making and/or lacked autonomy in the classroom. These causes trump low pay.

A major lesson of the study? Working conditions matter, and we neglect them at our peril. All too many students of color are leaking out of the pipeline to good jobs, especially in science, engineering and technology, so they need their role models to stick around.

The time elementary schools spend on science has been dwindling. According to at least one government source it dropped from 3 hours to just 2.3 hours a week between 1994 and 2008. What is a parent to do?

Scientific American has one strategy: Bring Science Home. Back in May, they launched a series of free science activities parents can do with their children. The activities are meant for kids aged are six to 12, and none of them require you to have the keys to your local particle accelerator. You can do them with objects and ingredients you're likely to have at home. A few of the experiments come with short, fun videos to show the experiments in action.

The Bring Science Home activities proved so popular that Scientific American has decided to offer a new experiment every week. The site has 21 activities and counting, enough for almost half a year of weekly fun and learning. Do you know kids between six and 12? Be sure to check with the site every Thursday for a new idea.

Should high schools be judged by their success in preparing their students for college? That idea has been gaining ground recently.

A couple of years ago, some plucky researchers found that some high schools getting great marks from state accountability systems were doing too hot on the college front. Even if their students were getting into college, many didn't survive past their freshman years. By contrast, graduates if some schools that fared poorly on state report cards did much better in college.

The plan to rate schools according to their graduates' success in college depends on data. Some 43 states now have the capacity to track individual students' progress from K-12 to the end of college, but only 23 are using these systems.

Kids of gotten the message that they should go to college--whether 2-year or 4-year programs--but huge numbers never get a degree. Should high schools be on the hook for how well they've equipped their graduates for success?

Just about everyone knew that Steve Jobs had suffered poor health for years, so the news last August that he was stepping down as Apple's CEO came as no great surprise. But the news of his passing yesterday, a scant 5 weeks later, was a great shock.

My family got its first Apple computer, an Apple II, in 1981. It was elegant and easy to use, a world apart from the clumsy, underpowered box we had owned before. For my brother, it was transformative. A high school student who never really warmed to his math and science classes, he spent hours each day on the computer, teaching himself to program. Thirty years later, he has a dream job creating special effects for movies.

Steve Jobs's miraculous little computer fired my brother's imagination the way school never had, and it set him on a completely new path. I'd wager that my brother's story is far from unusual.

Steve Jobs was a testament to the power of innovative people to create jobs, forge new industries, and chart entirely new directions for young people. He left us much too soon.

The new movie, Moneyball, features a bright young man using computer programs to determine which are the best baseball players to build a winning team.  How else might we use STEM to get ahead in the world of sport? Educators are always looking for accessible (free!) resources that can bring their lesson plans to life. So, what do youth care about other than what other kids are doing and celebrities?  One common theme is sports. How do those athletes do what they do?

There are new video resources that could be a boon for educators. Newton’s First Law of Motion helps determine whether a halfback sheds a tackler.  The basic law of physics demonstrates how an Olympic skater can execute a better jump.  These examples and many more involving the science and engineering of sport are offered in exciting short video clips at Science 360  brought to us by NBC Learn and the National Science Foundation.  Each clip is about 5 minutes long and showcases the latest wonders of science, engineering, technology and math as they are applied in the exciting world of sports.  Maybe with a little more physics education, that halfback can turn a third and one to a first and goal!
