Using Bridge Questions to Teach Technical Content Online | Online Education - Faculty Focus

Stefan A. Perun, assistant professor in the Department of Public Administration at Villanova University and Edward A. Liva, director of the Graduate Tax Program and a professor of practice at Villanova University School of Law reports, Courses with a great deal of technical content for application in practice such as law, business, or STEM courses are oftentimes designed in what amounts to an information delivery method.

The professor provides the necessary information for students to memorize and repeat back in the course assessments.
Indeed, the online environment makes disseminating recorded lectures and written material fast and convenient, and students readily expect to be tested on the materials provided. Even in course designs with synchronous components, professors may lecture or answer questions, yet seldom observe how students are synthesizing or interacting with the course material. Moreover, delivering large amounts of content and assessing students’ recall of that content misses a central piece of a student-centered pedagogy, namely ensuring that students achieve a deep understanding of the content through opportunities to apply the technical information to practical problems.

One way to augment online course designs that would help students practice applying technical knowledge is using bridge questions. Bridge questions require students to solve a practical problem or case by applying the content of the course to a real-world problem...

A final note on using bridge questions; the students’ independent and collaborative work on them should be graded, otherwise they may wait until others (especially the professor) solve the problems for them. In courses with synchronous components, this can be accomplished as a participation grade. In asynchronous designs, graded participation should be clearly defined activities that hold students accountable for engaging the bridge questions in meaningful ways. In any case, using bridge questions is a simple way to transform any online course from a content-focused passive learning experience to an engaging, students-centered one.

Science never quite clicked for me. Then I discovered YouTube | Op-Eds - gulfnews.com

Tom Hawking, freelance writer based in Melbourne recommends, Fascinating mathematical concepts explained in a way that’s entertaining.

YouTube has long had a reputation as a hive of conspiracy theories, misinformation, and pseudoscience. All these accusations are, more or less, true — if you’re vulnerable to the wooing of Flat Earthers, anti-vaxxers, 9/11 truthers, the alt-right, and every other sort of lunatic fringe flourishing in 2018, they’re all there, waiting for you on YouTube.

But as with all the other “platforms” that dominate the internet — Facebook, Twitter, Reddit, etc — YouTube is more than a morass of anti-scientific nutters. The site is also home to much of the web’s best and most compelling popular science content.  

Like pretty much everyone, I studied science and maths for the first few years of high school and eventually pursued chemistry and maths right through year 12. I found the concepts involved fascinating, but I was never much good at the actual work. I was less interested in learning how to solve quadratic equations than I was in why quadratic equations could be solved. What I wanted, I guess, was popular science. And one day a couple of years ago, tooling around on the internet while I should have been working, I found it on YouTube.

My YouTube rabbit hole started with Numberphile, the maths-based channel that forms part of Australian videographer Brady Haran’s YouTube empire...

It’s not just mathematics that benefits from the possibilities for visual illustration that YouTube allows. If you search, you’ll find people who take similar approaches to physics, chemistry, biology, electronics, along with a heap of generalists who address all these topics and more.

How can institutions enable experiential learning? | Education - Hindustan Times

With the days of rote learning behind us, and demand for experiential learning taking precedence, academic institutions will have to majorly transform their teaching methods, continues Hindustan Times.

A solid infrastructure is needed to overhaul the learning processes and create spaces that are conducive to experiential learning

The learning and development process of the Gen Z is undergoing massive changes with the advent of technology. The education system, by fueling the evolution of teaching methods and tools used in the classroom has been driven by the demands of the digital natives, whose lives revolve around digital screens and connected devices. Devices like PCs, laptops and printers have become the functional extension of this generation, at school as well as home.

With the days of rote learning behind us, and demand for experiential learning taking precedence, academic institutions will have to majorly transform their teaching methods. A solid infrastructure is needed to overhaul the learning processes and create spaces that are conducive to experiential learning. Around 51% of students surveyed in a Barnes and Noble College study, show that they learn best by doing, while only 12% said they learn through listening.1 So how can institutions enable this “learning by doing” experiential methodology in the classroom?

With technology improving the overall attitude toward learning, now more than ever, schools and colleges will have to put in concerted efforts to create a learning environment that focuses on problem-solving. After all, the real world is full of challenges that needs quick thinking for solutions. To make Gen Z students understand the real-life application of what they learn in the classroom we need to blend online and print mediums in equal proportion...

Digital learning goes beyond the four walls of educational institutes, reaching far and wide to those who want to learn on-demand, on their own time and even at their own suitable pace. Experiential learning complements this by giving an opportunity to apply the theoretical knowledge in practical domains. With the lives of Gen Z revolving around technology, the expectation of having digital learning tools deeply integrated into the education system and at the workplace is obvious.

Five ways colleges are remaking higher education from within | Opinion - Inside Higher Ed

As learners and employers seek education and training that is cheaper, faster and better, forward-looking colleges and universities are embracing new roles as curators, certifiers and integrators, writes Kathleen deLaski, founder and president of the Education Design Lab and Rufus Glasper, president and CEO of the League for Innovation in the Community College.

Higher education is being remade from within.

Federal policy is getting all the attention of late, with the U.S. Department of Education considering significant changes to the rules that shape higher education across the country and Congress simultaneously working to update the Higher Education Act for the first time in more than a decade. And both certainly stand to have a far-reaching impact on the landscape of colleges and universities.

But the real revolution in higher education isn’t being led by policy makers. It’s being driven by individual learners and employers who are demanding that learning become cheaper, better and faster. This is the learner revolution.
And we’ve learned some critical lessons about how to harness its potential over the past five years through the Education Design Lab’s work with over 100 forward-thinking colleges and universities...

We see five promising models for institutions looking to harness the learner revolution. These models -- highlighted in our new report, "The Learner Revolution: How Colleges Can Thrive in a New Skills and Competencies Marketplace" -- are informed by more than five years of experience using human-centered design to help institutions transform the learner experience.

Einstein's Wife Could Have Changed Physics If She Had The Chance: Book | Science -NDTV News

Erin Blakemore, The Washington Post explains, Was Albert Einstein's first wife more than his equal? Did she actually write his most famous theory? That rumor is laid to rest in "Einstein's Wife: The Real Story of Mileva Einstein-Maric," which separates truth from fiction. 

Claims surfaced in 1990 that Mileva Einstein-Maric had co-written her husband's theory of relativity

In October 1900, an enamored Albert Einstein wrote a note to his bride-to-be, Mileva Maric. "I'm so lucky to have found you, a creature who is my equal," he gushed.

But was Einstein's first wife more than his equal? Did she actually write his most famous theory? That rumor is laid to rest in "Einstein's Wife: The Real Story of Mileva Einstein-Maric," which separates truth from fiction. It tells the story of a brilliant but frustrated scientist who may well have changed physics - if she had ever gotten the chance.

David C. Cassidy, professor emeritus at Hoftstra University, sketches Maric's life. Science historian Ruth Lewin Sime places her in context alongside other women who struggled to make their mark on 20th-century science. And British mathematics and physics lecturer Allen Esterson unravels what the authors call the "Mileva Story."

That story gained steam during the 1990s, when claims surfaced that Mileva Einstein-Maric had co-written her husband's theory of relativity. The explosive contentions came at a time when the stories of female scientists were being rediscovered and the public was increasingly skeptical of science, writes Esterson - perfect conditions for the claim that Einstein-Maric had been overlooked...

In an era that was unapologetically hostile to women with scientific ambitions, she fought to study physics and mathematics. She excelled in those studies. But she was derailed by motherhood and marriage, which frustrated her ambitions.

While Thirdsday and Pi Day have passed for 2019, don't fret: there are still mathematical holidays to celebrate this year! Between Pi Day (March 14) and Tau Day (June 28) -- a celebration of the mathematical constant tau, which is equal to 2π -- there is a new mathematical holiday dedicated to celebrating women mathematicians! 

At the 2018 World Meeting for Women in Mathematics, (WM)^2 held in Rio de Janeiro, Brazil, the Women’s Committee of the Iranian Mathematical Society proposed designating Maryam Mirzakhani’s birthday (May 12) as a day for celebrating women in mathematics. The proposal was approved. Globally, several organizations for women in mathematics support the initiative, including European Women in Mathematics, the Association for Women in Mathematics, the African Women in Mathematics Association, the Colectivo de Mujeres Matemáticas de Chile (Collective of Women Mathematicians in Chile) and Indian Women and Mathematics.

Mirzakhani was the first woman and first Iranian to win the prestigious Fields Medal. "Mirzakhani specialized in theoretical mathematics that read like a foreign language by those outside of mathematics: moduli spaces, Teichmüller theory, hyperbolic geometry, Ergodic theory and symplectic geometry," according to a news release from Stanford University, where Mirzakhani was a mathematics professor until her death...

"May 12th is a joyful opportunity for the mathematical community to celebrate women in mathematics. The celebration takes place every year, all around the world...
