Study: Alphabetical Order of Surnames May Affect Grading

Par : msmash
22 avril 2024 à 20:41
AmiMoJo writes: Knowing your ABCs is essential to academic success, but having a last name starting with A, B or C might also help make the grade. An analysis by University of Michigan researchers of more than 30 million grading records from U-M finds students with alphabetically lower-ranked names receive lower grades. This is due to sequential grading biases and the default order of students' submissions in Canvas -- the most widely used online learning management system -- which is based on alphabetical rank of their surnames. What's more, the researchers found, those alphabetically disadvantaged students receive comments that are notably more negative and less polite, and exhibit lower grading quality measured by post-grade complaints from students.

Students Are Likely Writing Millions of Papers With AI

Par : BeauHD
12 avril 2024 à 02:02
Amanda Hoover reports via Wired: Students have submitted more than 22 million papers that may have used generative AI in the past year, new data released by plagiarism detection company Turnitin shows. A year ago, Turnitin rolled out an AI writing detection tool that was trained on its trove of papers written by students as well as other AI-generated texts. Since then, more than 200 million papers have been reviewed by the detector, predominantly written by high school and college students. Turnitin found that 11 percent may contain AI-written language in 20 percent of its content, with 3 percent of the total papers reviewed getting flagged for having 80 percent or more AI writing. Turnitin says its detector has a false positive rate of less than 1 percent when analyzing full documents.

Harvard Reinstates Standardized Testing Requirement

Harvard College is reinstating the requirement for standardized testing, reversing course on a pandemic-era policy that made them optional. It follows similar moves from elite universities like Yale, Dartmouth, and MIT. Axios reports: At Harvard, the mandate will be in place for students applying to begin school in fall 2025. Harvard had previously committed to a test-optional policy for applicants through the class of 2030, which would have started in fall 2026. Most students who applied since the pandemic began have submitted test scores despite the test-optional policy, the university said. Reviewing SAT/ACT scores as part of a student's application packet helps an admissions decision be holistic, the university said in a statement. "Standardized tests are a means for all students, regardless of their background and life experience, to provide information that is predictive of success in college and beyond," Hopi Hoekstra, a Harvard dean, said in the statement. "Indeed, when students have the option of not submitting their test scores, they may choose to withhold information that, when interpreted by the admissions committee in the context of the local norms of their school, could have potentially helped their application."

Code.org Launches AI Teaching Assistant For Grades 6-10 In Stanford Partnership

Par : BeauHD
11 avril 2024 à 22:40
theodp writes: From a Wednesday press release: "Code.org, in collaboration with The Piech Lab at Stanford University, launched today its AI Teaching Assistant, ushering in a new era of computer science instruction to support teachers in preparing students with the foundational skills necessary to work, live and thrive in an AI world. [...] Launching as a part of Code.org's leading Computer Science Discoveries (CSD) curriculum [for grades 6-10], the tool is designed to bolster teacher confidence in teaching computer science." EdWeek reports that in a limited pilot project involving twenty teachers nationwide, the AI computer science grading tool cut one middle school teacher's grading time in half. Code.org is now inviting an additional 300 teachers to give the tool a try. "Many teachers who lead computer science courses," EdWeek notes, "don't have a degree in the subject -- or even much training on how to teach it -- and might be the only educator in their school leading a computer science course." Stanford's Piech Lab is headed by assistant professor of CS Chris Piech, who also runs the wildly-successful free Code in Place MOOC (30,000+ learners and counting), which teaches fundamentals from Stanford's flagship introduction to Python course. Prior to coming up with the new AI teaching assistant, which automatically assesses Code.org students' JavaScript game code, Piech worked on a Stanford Research team that partnered with Code.org nearly a decade ago to create algorithms to generate hints for K-12 students trying to solve Code.org's Hour of Code block-based programming puzzles (2015 paper [PDF]). And several years ago, Piech's lab again teamed with Code.org on Play-to-Grade, which sought to "provide scalable automated grading on all types of coding assignments" by analyzing the game play of Code.org students' projects. Play-to-Grade, a 2022 paper (PDF) noted, was "supported in part by a Stanford Hoffman-Yee Human Centered AI grant" for AI tutors to help prepare students for the 21st century workforce. That project also aimed to develop a "Super Teaching Assistant" for Piech's Code in Place MOOC. LinkedIn co-founder Reid Hoffman, who was present for the presentation of the 'AI Tutors' work he and his wife funded, is a Code.org Diamond Supporter ($1+ million). In other AI grading news, Texas will use computers to grade written answers on this year's STAAR tests. The state will save more than $15 million by using technology similar to ChatGPT to give initial scores, reducing the number of human graders needed.

Professors Are Now Using AI to Grade Essays. Are There Ethical Concerns?

Par : EditorDavid
7 avril 2024 à 18:35
A professor at Ithaca College runs part of each student's essay through ChatGPT, "asking the AI tool to critique and suggest how to improve the work," reports CNN. (The professor said "The best way to look at AI for grading is as a teaching assistant or research assistant who might do a first pass ... and it does a pretty good job at that.") And the same professor then requires their class of 15 students to run their draft through ChatGPT to see where they can make improvements, according to the article: Both teachers and students are using the new technology. A report by strategy consultant firm Tyton Partners, sponsored by plagiarismâdetection platform Turnitin, found half of college students used AI tools in Fall 2023. Meanwhile, while fewer faculty members used AI, the percentage grew to 22% of faculty members in the fall of 2023, up from 9% in spring 2023. Teachers are turning to AI tools and platforms — such as ChatGPT, Writable, Grammarly and EssayGrader — to assist with grading papers, writing feedback, developing lesson plans and creating assignments. They're also using the burgeoning tools to create quizzes, polls, videos and interactives to up the ante" for what's expected in the classroom. Students, on the other hand, are leaning on tools such as ChatGPT and Microsoft CoPilot — which is built into Word, PowerPoint and other products. But while some schools have formed policies on how students can or can't use AI for schoolwork, many do not have guidelines for teachers. The practice of using AI for writing feedback or grading assignments also raises ethical considerations. And parents and students who are already spending hundreds of thousands of dollars on tuition may wonder if an endless feedback loop of AI-generated and AI-graded content in college is worth the time and money. A professor of business ethics at the University ofâVirginia "suggested teachers use AI to look at certain metrics — such as structure, language use and grammar — and give a numerical score on those figures," according to the article. ("But teachers should then grade students' work themselves when looking for novelty, creativity and depth of insight.") But a writer's workshop teacher at the University of Lynchburg in Virginia "also sees uploading a student's work to ChatGPT as a 'huge ethical consideration' and potentially a breach of their intellectual property. AI tools like ChatGPT use such entries to train their algorithms..." Even the Ithaca professor acknowledged to CNN that "If teachers use it solely to grade, and the students are using it solely to produce a final product, it's not going to work."

AI's Impact on CS Education Likened to Calculator's Impact on Math Education

Par : EditorDavid
6 avril 2024 à 18:34
In Communication of the ACM, Google's VP of Education notes how calculators impacted math education — and wonders whether generative AI will have the same impact on CS education: Teachers had to find the right amount of long-hand arithmetic and mathematical problem solving for students to do, in order for them to have the "number sense" to be successful later in algebra and calculus. Too much focus on calculators diminished number sense. We have a similar situation in determining the 'code sense' required for students to be successful in this new realm of automated software engineering. It will take a few iterations to understand exactly what kind of praxis students need in this new era of LLMs to develop sufficient code sense, but now is the time to experiment." Long-time Slashdot reader theodp notes it's not the first time the Google executive has had to consider "iterating" curriculum: The CACM article echoes earlier comments Google's Education VP made in a featured talk called The Future of Computational Thinking at last year's Blockly Summit. (Blockly is the Google technology that powers drag-and-drop coding IDE's used for K-12 CS education, including Scratch and Code.org). Envisioning a world where AI generates code and humans proofread it, Johnson explained: "One can imagine a future where these generative coding systems become so reliable, so capable, and so secure that the amount of time doing low-level coding really decreases for both students and for professionals. So, we see a shift with students to focus more on reading and understanding and assessing generated code and less about actually writing it. [...] I don't anticipate that the need for understanding code is going to go away entirely right away [...] I think there will still be at least in the near term a need to understand read and understand code so that you can assess the reliabilities, the correctness of generated code. So, I think in the near term there's still going to be a need for that." In the following Q&A, Johnson is caught by surprise when asked whether there will even be a need for Blockly at all in the AI-driven world as described — and the Google VP concedes there may not be.

Chronic Student Absenteeism Soars Across US

29 mars 2024 à 15:20
The US has seen a significant increase in student absenteeism since the pandemic closed schools four years ago, with an estimated 26% of public school students considered chronically absent in the last school year, up from 15% before the pandemic, according to data from 40 states and Washington, D.C. A report adds: The increases have occurred in districts big and small, and across income and race. For districts in wealthier areas, chronic absenteeism rates have about doubled, to 19 percent in the 2022-23 school year from 10 percent before the pandemic, a New York Times analysis of the data found. Poor communities, which started with elevated rates of student absenteeism, are facing an even bigger crisis: Around 32 percent of students in the poorest districts were chronically absent in the 2022-23 school year, up from 19 percent before the pandemic. Even districts that reopened quickly during the pandemic, in fall 2020, have seen vast increases.

Google Teams with 'Highlights', Shows How Goofus and Gallant Use the Internet

24 mars 2024 à 19:34
Long-time Slashdot reader theodp writes: Last month there was a special Google-funded edition of Highlights for Children, the 77-year-old magazine targetting children between the ages of 6 and 12. This edition was based on Google's "Be Internet Awesome" curriculum, and 1.25 million copies of the print magazine were distributed to children, schools, and other organizations. It's all part of a new partnership between Google and Highlights. A Google.org blog post calls out the special issue's Goofus and Gallant cartoon, in which always-does-the-wrong-thing Goofus "promised Kayden he wouldn't share the silly photo, but he shares it anyway", while always-does-the-right-thing Gallant "asks others if it's OK to share their photos"... theodp's orignal submission linked ironically to Slashdot's earlier story, "Google Hit With Lawsuit Alleging It Stole Data From Millions of Users To Train Its AI Tools." But even beyond that, it's not always clear what the cartoon is teaching. (In one picture it looks like they're condemning Goofus for not intervening in a flame war between two other people — "Be Kind!") Still, for me the biggest surprise is that Goofus and Gallant even have laptops. (How old are these kids, that they're already uploading photos of the other children onto the internet?!) Will 6- to 12-year-old children start demanding that their parents buy them their own laptop now — since even Goofus and Gallant already have them?

Universities Have a Computer-Science Problem

Par : msmash
21 mars 2024 à 16:00
theodp writes: "Last year," Ian Bogost writes in Universities Have a Computer-Science Problem, "18 percent of Stanford University seniors graduated with a degree in computer science, more than double the proportion of just a decade earlier. Over the same period at MIT, that rate went up from 23 percent to 42 percent. These increases are common everywhere: The average number of undergraduate CS majors at universities in the U.S. and Canada tripled in the decade after 2005, and it keeps growing. Students' interest in CS is intellectual -- culture moves through computation these days -- but it is also professional. Young people hope to access the wealth, power, and influence of the technology sector. That ambition has created both enormous administrative strain and a competition for prestige." "Another approach has gained in popularity," Bogost notes. "Universities are consolidating the formal study of CS into a new administrative structure: the college of computing. [...] When they elevate computing to the status of a college, with departments and a budget, they are declaring it a higher-order domain of knowledge and practice, akin to law or engineering. That decision will inform a fundamental question: whether computing ought to be seen as a superfield that lords over all others, or just a servant of other domains, subordinated to their interests and control. This is, by no happenstance, also the basic question about computing in our society writ large." Bogost concludes: "I used to think computing education might be stuck in a nesting-doll version of the engineer's fallacy, in which CS departments have been asked to train more software engineers without considering whether more software engineers are really what the world needs. Now I worry that they have a bigger problem to address: how to make computer people care about everything else as much as they care about computers.

Indiana Becomes 9th State To Make CS a High School Graduation Requirement

Par : BeauHD
19 mars 2024 à 00:45
Longtime Slashdot reader theodp writes: Last October, tech-backed nonprofit Code.org publicly called out Indiana in its 2023 State of Computer Science Education report, advising the Hoosier state it needed to heed Code.org's new policy recommendation and "adopt a graduation requirement for all high school students in computer science." Having already joined 49 other Governors who signed a Code.org-organized compact calling for increased K-12 CS education in his state after coming under pressure from hundreds of the nation's tech, business, and nonprofit leaders, Indiana Governor Eric J. Holcomb apparently didn't need much convincing. "We must prepare our students for a digitally driven world by requiring Computer Science to graduate from high school," Holcomb proclaimed in his January State of the State Address. Two months later -- following Microsoft-applauded testimony for legislation to make it so by Code.org partners College Board and Nextech (the Indiana Code.org Regional Partner which is also paid by the Indiana Dept. of Education to prepare educators to teach K-12 CS, including Code.org's curriculum) -- Holcomb on Wednesday signed House Bill 1243 into law, making CS a HS graduation requirement. The IndyStar reports students beginning with the Class of 2029 will be required to take a computer science class that must include instruction in algorithms and programming, computing systems, data and analysis, impacts of computing and networks and the internet. The new law is not Holcomb's first foray into K-12 CS education. Back in 2017, Holcomb and Indiana struck a deal giving Infosys (a big Code.org donor) the largest state incentive package ever -- $31M to bring 2,000 tech employees to Central Indiana — that also promised to make Indiana kids more CS savvy through the Infosys Foundation USA, headed at the time by Vandana Sikka, a Code.org Board member and wife of Infosys CEO Vishal Sikka. Following the announcement of the now-stalled deal, Holcomb led a delegation to Silicon Valley where he and Indiana University (IU) President Michael McRobbie joined Code.org CEO Hadi Partovi and Infosys CEO Vishal Sikka on a Thought Leader panel at the Infosys Confluence 2017 conference to discuss Preparing America for Tomorrow. At the accompanying Infosys Crossroads 2017 CS education conference, speakers included Sikka's wife Vandana, McRobbie's wife Laurie Burns McRobbie, Nextech President and co-CEO Karen Jung, Code.org execs, and additional IU educators. Later that year, IU 'First Lady' Laurie Burns McRobbie announced that Indiana would offer the IU Bloomington campus as a venue for Infosys Foundation USA's inaugural Pathfinders Summer Institute, a national event for K-12 teacher education in CS that offered professional development from Code.org and Nextech, as well as an unusual circumvent-your-school's-approval-and-name-your-own-stipend funding arrangement for teachers via an Infosys partnership with the NSF and DonorsChoose that was unveiled at the White House. And that, Schoolhouse Rock Fans, is one more example of how Microsoft's National Talent Strategy is becoming Code.org-celebrated K-12 CS state laws!

Nvidia Founder Tells Stanford Students Their High Expectations May Make It Hard For Them To Succeed

Par : BeauHD
13 mars 2024 à 23:20
An anonymous reader quotes a report from Fortune: We are often told that setting the bar high is key to success. After all, if you shoot for the moon and miss, at least you'll land with the stars. But Nvidia's CEO Jensen Huang wants privileged Gen Z grads to lower their expectations. "People with very high expectations have very low resilience -- and unfortunately, resilience matters in success," Huang said during a recent interview with the Stanford Graduate School of Business. "One of my great advantages is that I have very low expectations." Indeed, as the billionaire boss pointed out, those at elite institutions like Stanford probably have higher expectations for their future than your average Joe. The university is one of the most selective in the United States -- it ranks third best in the country, according to the QS World University Rankings, and the few students who get picked to study there are charged $62,484 in tuition fees for the premium, compared to the average $26,027 per annum cost. But, unfortunately for those saddled with student debt, not even the best universities in the world can teach you resilience. "I don't know how to teach it to you except for I hope suffering happens to you," Huang added. [...] For those fortunate enough to never have personally experienced hardship growing up, Huang doesn't have any advice on how to welcome more of it into your life now. But he did have some advice on embracing tough times. "I don't know how to do it [but] for all of you Stanford students, I wish upon you ample doses of pain and suffering," Huang said. "Greatness comes from character and character isn't formed out of smart people -- it's formed out of people who suffered."It's why despite Nvidia's success -- the company has a $2 trillion market cap -- Huang would still welcome hardship at his organization."To this day I use the phrase 'pain and suffering' inside our company with great glee," he added. "I mean that in a happy way because you want to refine the character of your company." Essentially, if you want your workforce to always be on their A game, don't let them rest on their laurels.

Who Uses Legacy Admissions?

Par : msmash
13 mars 2024 à 20:40
Following the U.S. Supreme Court's decision to end affirmative action in college admissions, there has been increased scrutiny on legacy admissions -- the practice of giving special considerations to the relatives of alumni. Critics say this practice disproportionately benefits white students from wealthy backgrounds. Much of the discussion and research on legacy admissions focuses on Ivy League and other highly selective schools, but these colleges enroll only a small share of students. How widespread is the practice of legacy admissions? Is it common among public colleges? Brookings: In this report, we document the prevalence of legacy admissions, as reported by colleges, across higher education around the time of the SFFA decision. Legacy admissions were more often used at selective and private institutions, but a substantial minority of public and less selective institutions also considered legacy status in admissions. The use of legacy preferences appears to have been most common in the Northeast and South and least common in the West. There is substantial -- but incomplete -- overlap in the colleges that considered legacy status and those that practiced affirmative action (AA) prior to SFFA. A number of colleges, including some public colleges, said they considered relationships to alumni but not racial identity in admissions. While most state flagships don't consider legacy status in admissions, half have at least one scholarship opportunity that is catered to legacy students. Because the data are available with a lag, we do not know how many colleges have changed their legacy admissions policies in response to the Court's decision on affirmative action, but press reports and our conversations with admissions representatives indicate that some colleges have changed course in the past few years, including at least five state flagships. The effect of legacy preferences on who enrolls at a particular university may not be substantial overall. Many of the colleges that use legacy admissions are not that selective, and the scholarships for relatives of alumni are typically small. Still, even if the number of students directly displaced by legacies who had a leg up is ultimately not that large, the practice sends students the wrong signal about what's important and is contrary to the mission of a public university. In a recent survey, half of first-generation college students said they thought legacy admissions practices may have hurt their chances. Perceptions of an unfair admissions process might also make some students less likely to apply or undermine the perceived legitimacy of higher education, though we did not find research on this topic.

U. of Texas at Austin Will Return To Standardized Test Requirement

Par : msmash
11 mars 2024 à 19:20
The University of Texas at Austin said Monday that it would again require standardized tests for admissions (non-paywalled source), becoming the latest selective university to reinstate requirements for SAT or ACT scores that were abandoned during the pandemic. From a report: A few years ago, about 2,000 colleges across the country began to move away from requiring test scores, at least temporarily, amid concerns they helped fuel inequality. But a growing number of those schools have reversed those policies, including Brown, Yale, Dartmouth, M.I.T., Georgetown and Purdue, with several announcing the changes in recent months. U.T. Austin, which admits a cross-section of high-achieving Texas students under a plan designed to increase opportunity in the state, cited a slightly different reason than the other schools in returning to test requirements. Without requiring test scores, officials said, they were hampered in placing the admitted students in programs they would be most suited for and in determining which ones needed extra help. After making test scores optional the past few years, the university will now require applicants to submit either SAT or ACT scores beginning Aug. 1, with applications for fall 2025 admissions. In an interview, Jay Hartzell, the U.T. president, said that the decision followed an analysis of students who did not submit scores. "We looked at our students and found that, in many ways, they weren't faring as well," Dr. Hartzell said. Those against testing requirements have long said that standardized tests are unfair because many students from affluent families use tutors and coaches to bolster their scores. But recent data has raised questions about the contention. In reinstating test requirements, some universities have said that making scores optional had the unintended effect of harming prospective students from low-income families.

Teachers Are Embracing ChatGPT-Powered Grading

Par : BeauHD
7 mars 2024 à 10:00
Schools are widely adopting a new tool called Writable that uses ChatGPT to help grade student writing assignments. Axios reports: Writable, which is billed as a time-saving tool for teachers, was purchased last month by education giant Houghton Mifflin Harcourt, whose materials are used in 90% of K-12 schools. Teachers use it to run students' essays through ChatGPT, then evaluate the AI-generated feedback and return it to the students. A teacher gives the class a writing assignment -- say, "What I did over my summer vacation" -- and the students send in their work electronically. The teacher submits the essays to Writable, which in turn runs them through ChatGPT. ChatGPT offers comments and observations to the teacher, who is supposed to review and tweak them before sending the feedback to the students. Writable "tokenizes" students' information so that no personally identifying details are submitted to the AI program.
