How to teach kids who flip between book and screen


The use of digital books and textbooks exploded during the pandemic, and it may be only a matter of time before all educational publishing moves online. So it’s all the more important to keep making digital reading better for students, says literacy educator Tim Shanahan. Instead of trying to make the digital technology more like a book, Shanahan has written, “[engineers] need to think about how to produce better digital tools. Tech environments can alter reading behavior, so technological scaffolding could be used to slow us down or to move around a text more productively.” In the future, students might read about history or science from something like a “tap essay,” where words, sentences, and images are revealed only when a reader is ready and taps the screen to move on to the next piece of text. Or maybe their reading material will look more like a New York Times digital article, in which text, images, video, and sound clips are spaced out and blended together in different ways.

Hooked on computer phonics 

About two-thirds of American schoolchildren can’t read at grade level. At least partly to blame is a widespread method of reading instruction that dominated classrooms for 40 years but was not based on scientific evidence about how the brain learns to read: “balanced literacy,” and its close cousin “whole language,” deemphasized explicit instruction in reading’s foundational skills, leaving many children struggling. But over the last several years, a new method strongly focused on these foundational skills, often referred to as the “science of reading,” has brought sweeping changes to the US education system. Based on decades of scientific evidence, the “science of reading” approach is organized into five areas: phonemic awareness (learning all the sounds of the English language), phonics (learning how those sounds are attached to letters), vocabulary, comprehension, and fluency.

Learn-to-read apps and digital platforms have the potential to teach some of these foundational skills efficiently. They’re especially well suited to phonemic awareness and phonics, making learning letters and sound combinations a game and reinforcing the skills with practice. Lexia, arguably the most widespread digital platform devoted to the science of reading, teaches basic and complex foundational reading skills, like letter-sound blends and spelling rules, using responsive technology. When learning a specific skill, such as figuring out how to read words like meal and seam with the “ea” vowel combination in the middle, students can’t move on until they’ve mastered it. 

Digital platforms can reinforce certain specific reading skills, but it’s the teacher who is constantly monitoring the student’s progress and adjusting the instruction as needed.

A new wave of predictive reading platforms goes one step further. Companies like Microsoft and SoapBoxLabs are envisioning a world where students can learn to read entirely via computer. Using AI speech recognition technology, the companies claim, these digital platforms can listen closely to a student reading. Then they can identify trouble spots and offer help accordingly. 

As digital tech for learning to read spreads into schools—Lexia alone serves more than 3,000 school districts—some reading experts are wary. Research on its efficacy is limited. While some see technology playing a useful role in reading-related functions like assessing students and even training teachers, many say that when it comes to actually doing the teaching, humans are superior. 

Digital platforms can reinforce certain specific reading skills, explains Heidi Beverine-Curry, chief academic officer of the teacher training and research organization The Reading League, but it’s the teacher who is constantly monitoring the student’s progress and adjusting the instruction as needed. 

Faith Borkowsky, founder of High Five Literacy, a tutoring and consultancy service in Plainview, New York, is not bothered by reading instruction apps per se. “If it happens to be a computer program where a few kids could go on and practice a certain skill, I’d be all for it, if it aligns with what we are doing,” she says. But often that’s not how it plays out in classrooms. 

In the Long Island schools Borkowsky works with, it’s more likely that students do more reading work on laptops because schools purchased expensive technology and feel pressured to use it—even if it’s not always the best way to teach reading skills. “What I’ve seen in schools is they have a program, and they say, ‘Well, we bought it—now we have to use it.’ Districts find it hard to turn back after purchasing expensive programs and materials,” she says.

The hunter-gatherer groups at the heart of a microbiome gold rush

The hunter-gatherer groups at the heart of a microbiome gold rush


The first step to finding out is to catalogue what microbes we might have lost. To get as close to ancient microbiomes as possible, microbiologists have begun studying multiple Indigenous groups. Two have received the most attention: the Yanomami of the Amazon rainforest and the Hadza, in northern Tanzania. 

Researchers have made some startling discoveries already. A study by Sonnenburg and his colleagues, published in July, found that the gut microbiomes of the Hadza appear to include bugs that aren’t seen elsewhere—around 20% of the microbe genomes identified had not been recorded in a global catalogue of over 200,000 such genomes. The researchers found 8.4 million protein families in the guts of the 167 Hadza people they studied. Over half of them had not previously been identified in the human gut.

Plenty of other studies published in the last decade or so have helped build a picture of how the diets and lifestyles of hunter-gatherer societies influence the microbiome, and scientists have speculated on what this means for those living in more industrialized societies. But these revelations have come at a price.

A changing way of life

The Hadza people hunt wild animals and forage for fruit and honey. “We still live the ancient way of life, with arrows and old knives,” says Mangola, who works with the Olanakwe Community Fund to support education and economic projects for the Hadza. Hunters seek out food in the bush, which might include baboons, vervet monkeys, guinea fowl, kudu, porcupines, or dik-dik. Gatherers collect fruits, vegetables, and honey.

Mangola, who has met with multiple scientists over the years and participated in many research projects, has witnessed firsthand the impact of such research on his community. Much of it has been positive. But not all researchers act thoughtfully and ethically, he says, and some have exploited or harmed the community.

One enduring problem, says Mangola, is that scientists have tended to come and study the Hadza without properly explaining their research or their results. They arrive from Europe or the US, accompanied by guides, and collect feces, blood, hair, and other biological samples. Often, the people giving up these samples don’t know what they will be used for, says Mangola. Scientists get their results and publish them without returning to share them. “You tell the world [what you’ve discovered]—why can’t you come back to Tanzania to tell the Hadza?” asks Mangola. “It would bring meaning and excitement to the community,” he says.

Some scientists have talked about the Hadza as if they were living fossils, says Alyssa Crittenden, a nutritional anthropologist and biologist at the University of Nevada in Las Vegas, who has been studying and working with the Hadza for the last two decades.

The Hadza have been described as being “locked in time,” she adds, but characterizations like that don’t reflect reality. She has made many trips to Tanzania and seen for herself how life has changed. Tourists flock to the region. Roads have been built. Charities have helped the Hadza secure land rights. Mangola went abroad for his education: he has a law degree and a master’s from the Indigenous Peoples Law and Policy program at the University of Arizona.

The Download: a microbiome gold rush, and Eric Schmidt’s election misinformation plan


Over the last couple of decades, scientists have come to realize just how important the microbes that crawl all over us are to our health. But some believe our microbiomes are in crisis—casualties of an increasingly sanitized way of life. Disturbances in the collections of microbes we host have been associated with a whole host of diseases, ranging from arthritis to Alzheimer’s.

Some might not be completely gone, though. Scientists believe many might still be hiding inside the intestines of people who don’t live in the polluted, processed environment that most of the rest of us share. They’ve been studying the feces of people like the Yanomami, an Indigenous group in the Amazon, who appear to still have some of the microbes that other people have lost. 

But there is a major catch: we don’t know whether those in hunter-gatherer societies really do have “healthier” microbiomes—and if they do, whether the benefits could be shared with others. At the same time, members of the communities being studied are concerned about the risk of what’s called biopiracy—taking natural resources from poorer countries for the benefit of wealthier ones.

Navigating a shifting customer-engagement landscape with generative AI

Navigating a shifting customer-engagement landscape with generative AI


A strategic imperative

Generative AI’s ability to harness customer data in a highly sophisticated manner means enterprises are accelerating plans to invest in and leverage the technology’s capabilities. In a study titled “The Future of Enterprise Data & AI,” Corinium Intelligence and WNS Triange surveyed 100 global C-suite leaders and decision-makers specializing in AI, analytics, and data. Seventy-six percent of the respondents said that their organizations are already using or planning to use generative AI.

According to McKinsey, while generative AI will affect most business functions, “four of them will likely account for 75% of the total annual value it can deliver.” Among these are marketing and sales and customer operations. Yet, despite the technology’s benefits, many leaders are unsure about the right approach to take and mindful of the risks associated with large investments.

Mapping out a generative AI pathway

One of the first challenges organizations need to overcome is senior leadership alignment. “You need the necessary strategy; you need the ability to have the necessary buy-in of people,” says Ayer. “You need to make sure that you’ve got the right use case and business case for each one of them.” In other words, a clearly defined roadmap and precise business objectives are as crucial as understanding whether a process is amenable to the use of generative AI.

The implementation of a generative AI strategy can take time. According to Ayer, business leaders should maintain a realistic perspective on the duration required for formulating a strategy, conduct necessary training across various teams and functions, and identify the areas of value addition. And for any generative AI deployment to work seamlessly, the right data ecosystems must be in place.

Ayer cites WNS Triange’s collaboration with an insurer to create a claims process by leveraging generative AI. Thanks to the new technology, the insurer can immediately assess the severity of a vehicle’s damage from an accident and make a claims recommendation based on the unstructured data provided by the client. “Because this can be immediately assessed by a surveyor and they can reach a recommendation quickly, this instantly improves the insurer’s ability to satisfy their policyholders and reduce the claims processing time,” Ayer explains.

All that, however, would not be possible without data on past claims history, repair costs, transaction data, and other necessary data sets to extract clear value from generative AI analysis. “Be very clear about data sufficiency. Don’t jump into a program where eventually you realize you don’t have the necessary data,” Ayer says.

The benefits of third-party experience

Enterprises are increasingly aware that they must embrace generative AI, but knowing where to begin is another thing. “You start off wanting to make sure you don’t repeat mistakes other people have made,” says Ayer. An external provider can help organizations avoid those mistakes and leverage best practices and frameworks for testing and defining explainability and benchmarks for return on investment (ROI).

Using pre-built solutions by external partners can expedite time to market and increase a generative AI program’s value. These solutions can harness pre-built industry-specific generative AI platforms to accelerate deployment. “Generative AI programs can be extremely complicated,” Ayer points out. “There are a lot of infrastructure requirements, touch points with customers, and internal regulations. Organizations will also have to consider using pre-built solutions to accelerate speed to value. Third-party service providers bring the expertise of having an integrated approach to all these elements.”
