How bad were Ofqual's grades - by Huy Duong - HEPI - 0 views

  •  
    "Therefore even Ofqual's best model significantly worsened grade accuracy for most A-level subjects when the cohort size is below 50, which is common (almost 62% of the total in 2019). For GCSEs, even with larger cohorts, the best model would have worsened the grade accuracy for Maths and Sciences. A very conservative figure of 25% of wrong grades would have amounted to 180,000 wrong A-level grades and 1.25 million wrong GCSE grades."

Chinese schools are testing AI that grades papers almost as well as teachers | VentureBeat - 0 views

  •  
    "It is also self-improving. The 10-year-old grading software leverages deep learning algorithms to "compare notes" with human teachers' scores, suggestions, and comments. An engineer involved in the project compared its capabilities to those of AlphaGo, the record-breaking AI Go player developed by Google subsidiary DeepMind."

The UK government's voice-over-IP standard is designed to be backdoored / Boing Boing - 0 views

  •  
    "GCHQ, the UK's spy agency, designed a security protocol for voice-calling called MIKEY-SAKKE and announced that they'll only certify VoIP systems as secure if they use MIKEY-SAKKE, and it's being marketed as "government-grade security." But a close examination of MIKEY-SAKKE reveals some serious deficiencies. The system is designed from the ground up to support "key escrow" -- that is, the ability of third parties to listen in on conversations without the callers knowing about it."

When Your Boss Is an Algorithm - New York Times Opinion - Medium - 0 views

  •  
    "The algorithmic manager seems to watch everything you do. Ride-hailing platforms track a variety of personalized statistics, including ride acceptance rates, cancellation rates, hours spent logged in to the app and trips completed. And they display selected statistics to individual drivers as motivating tools, like "You're in the top 10 percent of partners!" Uber uses the accelerometer in drivers' phones along with GPS and gyroscope to give them safe driving reports, tracking their performance in granular detail. One driver posted to a forum that a grade of 210 out of 247 "smooth accelerations" earned a "Great work!" from the boss."

    "The company, Unacast, went live with its Social Distancing Scoreboard Tuesday. The dashboard, billed as a public health utility, includes a county-by-county breakdown of people's movement patterns. It assigns each county a grade, which Unacast based (at least in part) on how much people are traveling. "

Students are Better Off without a Laptop in the Classroom - Scientific American - 0 views

  •  
    "New research by scientists at Michigan State University suggests that laptops do not enhance classroom learning, and in fact students would be better off leaving their laptops in the dorm during class. Although computer use during class may create the illusion of enhanced engagement with course content, it more often reflects engagement with social media, YouTube videos, instant messaging, and other nonacademic content. This self-inflicted distraction comes at a cost, as students are spending up to one-third of valuable (and costly) class time zoned out, and the longer they are online the more their grades tend to suffer."

AI bot ChatGPT stuns academics with essay-writing skills and usability | Technology | T... - 0 views

  •  
    "Dan Gillmor, a journalism professor at Arizona State University, asked the AI to handle one of the assignments he gives his students: writing a letter to a relative giving advice regarding online security and privacy. "If you're unsure about the legitimacy of a website or email, you can do a quick search to see if others have reported it as being a scam," the AI advised in part. "I would have given this a good grade," Gillmor said. "Academia has some very serious issues to confront.""

More Accurate Than Test Scores: Scientists Discover a New Way To Measure Learning - 0 views

    "Brain scans predict students' learning better than exam results and show the underlying structure of thinking. According to recent research published in Science Advances, the conventional exams and grades that schools have long employed may evaluate learning less accurately than brain scans."

Teachers in Denmark are using apps to audit their student's moods | MIT Technology Review - 0 views

  •  
    "In a Copenhagen suburb, a fifth-grade classroom is having its weekly cake-eating session, a common tradition in Danish public schools. While the children are eating chocolate cake, the teacher pulls up an infographic on a whiteboard: a bar chart generated by a digital platform that collects data on how they've been feeling. Organized to display the classroom's weekly "mood landscape," the data shows that the class averaged a mood of 4.4 out of 5, and the children rated their family life highly. "That's great!" the teacher exclaims, raising two thumbs up in the air. She then moves to an infographic on sleep hygiene. Here the data shows the students struggling, and the teacher invites them to think of ways to improve their sleeping habits. After briefly talking among themselves, the children suggest "less screen time at night," "meditation before sleep," and "having a hot bath." They collectively make a commitment to implement these strategies. At next week's cake time, they will be asked whether or not they followed through."

Shut Down the Parent Portals: The Dangers of Real-Time Data | Just Visiting - 0 views

  •  
    "Parent "Portals," as utilized in K12 education, are doing significant harm to student development.[1] For those not familiar, Parent Portals are learning management systems that provide "real time" information to parents of school-aged children: "grades, attendance, assignments, and more." On a daily basis parents can monitor their child's performance in school and intervene at home. In theory, this seems like a good thing. But what is the difference between "real time" data and constant surveillance? In my view, not much. What if surveillance is not conducive to education? I'm working this one out. Let's see where it goes."

From Trump Nevermind babies to deep fakes: DALL-E and the ethics of AI art | Artificial... - 0 views

  •  
    ""We are seeing deep fakes being used all the time, and the technology is going to allow still images, but ultimately also video images, to be synthesised [more easily] by bad actors," he says. DALL-E has content policy rules in place that prohibit bullying, harassment, the creation of sexual or political content, or creating images of people without their consent. And while Open AI has limited the number of people who can sign up to DALL-E, its lower-grade replica, DALL-E mini, is open access, meaning people can produce anything they want."
