a new paper in Applied Cognitive Psychology….
231 student participants to watch two YouTube videos (one on real estate appraisals and the other on the Roman Empire) at normal speed, 1.5x speed, 2x speed or 2.5x speed. They were told to watch the videos in full screen mode and not to pause them or take any notes. After each video, the students took comprehension tests, which were repeated a week later. The results were clear: the 1.5x and 2x groups did just as well on the tests as those who’d watched the videos at normal speed, both immediately afterwards and one week on. Only at 2.5x was learning impaired.
When the team surveyed a separate group of UCLA students, they found that a massive 85% usually watched pre-recorded lectures at faster than normal speed. However, 91% said they thought that normal speed or slightly faster (1.5x) would be better for learning than 2x or 2.5x. These new results certainly suggest that this isn’t right: double-time viewing was just as good as normal viewing.
While 2x viewing was fine for learning about the material in their studies — real estate appraisals and the Roman Empire — perhaps it might not work for more complex subject matter; again, only more research will tell.

The Still-Evolving Future of University Credentials
https://www.edsurge.com/news/2021-12-21-the-still-evolving-future-of-university-credentials
Sean Gallagher is founder and executive director of Northeastern University’s Center for the Future of Higher Education and Talent Strategy, and executive professor of educational policy.
The growth of educational platform companies such as Coursera and 2U is being driven in part by a surge in demand for certificate programs and “alternative credential” offerings. The number of open badges awarded nearly doubled from 24 million in 2018 to 43 million in 2020. And major companies and industry groups are increasingly getting into the credentialing game, exemplified by firms such as IBM and Google. Strada Education Network’s consumer polling has shown that 40 percent of working-age adults have earned some type of non-degree credential—and that non-degree credentials are at the top of the list for adults seeking education or retraining.
plenty of confusion or ignorance in the marketplace about the basic differences between “certificates” and “certifications.”
skills-based hiring
badging, embedding certificates into degrees and the idea of offering small credentials on the way to a larger one are emerging as key trends
The future will likely see a continued de-emphasis on merely requiring that prospective employees hold college degrees.
the needs of the job market are changing faster than ever, meaning a greater need for upskilling
a new national survey of C-suite executives that we recently conducted, 70 percent said that U.S. workers should be worried about their skills becoming outdated over the next few years.
Innovations such as stackable non-degree credentials as an on-ramp and low-cost MOOC-based degrees from top universities are likely to only grow access to post-baccalaureate education. The number of MOOC-based degrees is approaching 100
Online education services companies – or “OPMs” as many refer to them, have continued to play a major role in the scaling of online higher education, within, and now increasingly beyond the U.S.

Microsoft and Samsung are collaborating on new augmented reality project
https://www.windowscentral.com/microsoft-and-samsung-team-new-augmented-reality-project-says-report
All that is known is that the project is AR-related and may involve some sort of hardware Samsung will be producing (rather than Microsoft). Samsung’s investments in DigiLens, the company behind tech found in AR display devices, may further substantiate the idea that the former will be handling the physical gadgetry in its collaboration with Microsoft.

More than 300 scientists have told Mark Zuckerberg they want access to Meta’s internal research on child and teen mental health because it doesn’t meet scientific standards
https://www.businessinsider.com/mark-zuckerberg-meta-open-letter-kids-mental-health-300-scientists-2021-12
The letter concludes by asking Meta to create an independent oversight trust that would monitor and study adolescent and child mental health.
Instagram CEO Adam Mosseri is due to testify before Congress about children’s safety on the platform Tuesday.
a Forrester survey of 4,602 Americans aged 12 to 17, published last month, found that 63% of respondents used TikTok on a weekly basis compared with 57% for Instagram. It also found 72% of respondents used YouTube weekly. It did not mention Facebook.
Today’s College Students Care About Privacy — Despite Some of Their Online Actions
https://www.edsurge.com/news/2021-11-02-today-s-college-students-care-about-privacy-despite-some-of-their-online-actions
a new report from the nonprofit Future of Privacy Forum, which analyzed recent research about young adults from the U.S., China, Germany and Japan.
a study from Indiana University detailed the fears college students have about and the ways they adapt to the fact that they may be photographed at any moment by friends, classmates or even strangers.
Another worry described in the Future of Privacy Forum report is about a type of digital harassment known as “doxxing,”
Many students are loath to share biometric information with colleges and are wary about tools like facial recognition software.
WHY TECHNOLOGY FAVORS TYRANNY
https://www.theatlantic.com/magazine/archive/2018/10/yuval-noah-harari-technology-tyranny/568330/
Artificial intelligence could erase many practical advantages of democracy, and erode the ideals of liberty and equality. It will further concentrate power among a small elite if we don’t take steps to stop it.
liberal democracy and free-market economics might become obsolete.
The Russian, Chinese, and Cuban revolutions were made by people who were vital to the economy but lacked political power; in 2016, Trump and Brexit were supported by many people who still enjoyed political power but feared they were losing their economic worth.
artificial intelligence is different from the old machines. In the past, machines competed with humans mainly in manual skills. Now they are beginning to compete with us in cognitive skills. And we don’t know of any third kind of skill—beyond the manual and the cognitive—in which humans will always have an edge.
Israel is a leader in the field of surveillance technology, and has created in the occupied West Bank a working prototype for a total-surveillance regime.
The conflict between democracy and dictatorship is actually a conflict between two different data-processing systems. AI may swing the advantage toward the latter.
As we rely more on Google for answers, our ability to locate information independently diminishes. Already today, “truth” is defined by the top results of a Google search.
The race to accumulate data is already on, and is currently headed by giants such as Google and Facebook and, in China, Baidu and Tencent. So far, many of these companies have acted as “attention merchants”—they capture our attention by providing us with free information, services, and entertainment, and then they resell our attention to advertisers.
We aren’t their customers—we are their product.
Nationalization of data by governments could offer one solution; it would certainly curb the power of big corporations. But history suggests that we are not necessarily better off in the hands of overmighty governments.
