Giving Rural Kids Computers and Seeing What Happens

Sugata Mitra's TED Talk starts with these words: "There are places on Earth, in every country, where, for various reasons, good schools cannot be built and good teachers cannot or do not want to go...." From this jumping-off point, Indian education scientist Mitra shows us a variety of experiments in which he placed computers with internet access in contexts where kids could experiment with them on their own -- without teachers. "At the end of [the early experiments], we concluded that groups of children can learn to use computers sand the internet on their own, irrespective of who or where they were. At that point I became a little more ambitious, and decided to see -- what else could children do with a computer?"

This talk is frequently surprising and delightful, partly because Mitra's experimental design is delightful on its own (he tends to give kids a simple starting point and then, without much explanation, simply leaves for a few weeks). While it is not about replacing teachers with machines (despite what Arthur C. Clarke suggests during the talk), it's all about how kids can and do teach themselves about topics that interest them. It isn't always positive (there's an amusing bit around the six-minute mark about kids using the web to cheat on homework assignments), but it's certainly an impressive story and a worthy set of experiments. Particularly interesting is when Mitra attempts to figure out which topics must be taught with the aid of a teacher.

What Have You Taught Yourself?

After watching this talk, I'm reminded that in many cases, the computer skills I use daily are mostly self-taught. In many ways, I was like the kids in this experiment -- as a young kid, a computer showed up in my house (and to some extent in school and the library, though access was limited) and I was encouraged to play with it. From there came skills like touch typing (which I only truly learned when I got a job as typist), software development, graphic design, computer repair, and, I'll admit it, a fair number of games. How about you?

Why Reading Aloud Helps You Remember More Information

If you're trying to commit something to memory, you shouldn't just read the same flashcard over and over. You should read it aloud, according to a new study from the University of Waterloo in Ontario, Canada.

The research, published in the journal Memory, finds that the act of reading and speaking text aloud is a more effective way to remember information than reading it silently or just hearing it read aloud. The dual effect of both speaking and hearing helps encode the memory more strongly, the study reports. The new research builds on previous work on the so-called production effect by Waterloo psychologist Colin MacLeod, who is also one of the current paper's authors.  

The current study tested 95 college students over the course of two semesters, asking them to remember as many words as possible from a list of 160 nouns. At one session, they read a list of words into a microphone, then returned two weeks later for a follow-up. In some situations, the participants read the words presented to them aloud, while in others, they either heard their own recorded voice played back to them, heard recordings of others reading the words, or read the words silently to themselves. Afterward, they were tested to see how much they remembered from the list.

The participants remembered more words if they had read them aloud compared to all other conditions, even the one where people heard their own voices reading the words. However, hearing your own voice on its own does seem to have some effect: it was a better memory tool for participants than hearing someone else speak, perhaps because people are good at remembering things that involve them. (Or maybe, the researchers suggest, it's just because people find it so bizarre to hear their own recorded voice that it becomes a salient memory.)

The findings "suggest that production is memorable in part because it includes a distinctive, self-referential component," the researchers write. "This may well underlie why rehearsal is so valuable in learning and remembering: We do it ourselves, and we do it in our own voice. When it comes time to recover the information, we can use this distinctive component to help us to remember."

The message is loud and clear: If you want to remember, you should both read it and speak it aloud.

The Brooklyn Public Library is Now Home to a Tiny Mollusk Museum

The Brooklyn Public Library is one of America’s largest public libraries—and now, its lobby is home to what’s being billed as the world’s smallest mollusk museum (and its first, no less). The vending machine-sized installation contains 15 different educational “displays,” all of which highlight fun facts about bivalves, snails, octopuses, and other soft-bodied creatures, according to The Washington Post.

Installed on November 10, the mollusk museum is the brainchild of Amanda Schochet, a computational ecologist, and media producer Charles Philipp. In 2016 they co-founded MICRO, a nonprofit organization that makes and distributes compact science museums.

“Science museums are amazing,” the duo said in a video about their company, which is supported by Science Sandbox, an initiative of the Simons Foundation. “There’s just not enough of them. They’re all in wealthier neighborhoods. It’s fundamentally important for everyone to have access. So we decided to reinvent the museum, taking everything that we love about museums and putting it inside a box that can go anywhere.”

The factory-made museums are designed in collaboration with scientists, and created using 3D printing techniques. They’re easily reproduced, and can be set up anywhere, including libraries, airports, or even the DMV.

The BPL’s Smallest Mollusk Museum is MICRO’s first public project. Why mollusks, you might ask? For one thing, they survive in every habitat on Earth, and have evolved over hundreds of millions of years. Plus, a mollusk museum of any type—large or small—didn’t exist yet, as Schochet learned after she once misheard Philipp say he was going to the world’s “mollusk museum.” (He was instead going to the “smallest” one, located inside a Manhattan elevator shaft.)

The Smallest Mollusk Museum is “packed with exhibits including miniature movie theaters, 3D-printed sculptures of octopus brains and leopard slug hugs, optical illusions showing visitors what it’s like to experience the world as mollusks, and a holographic mollusk aquarium,” Schochet tells Mental Floss. “We've identified nearly 100,000 species of mollusks, but there could be as many as 200,000—they’re all around us, all the time. Every one of them is a lens onto a bigger universe.”

Librarians have also joined in on the mollusk mania, prepping an accompanying series of books for kids and adults about the many creatures featured in the museum's exhibits.

The Smallest Mollusk Museum will gradually circulate through several of the library system’s branches. Meanwhile, MICRO’s next public offering will be a second mollusk museum, which will open in the Ronald McDonald House in New York City in December 2017. Additional locations and projects—including a small physics museum called the Perpetual Motion Museum—will be announced soon.
