What a 3D Printer Taught Me About Learning

If you aren’t an ardent follower of the maker movement, or involved in it yourself, you might have missed the hype about 3D printing. 3D printing has grown from a niche market for creating small prototypes or parts into a multi-billion dollar business spanning industries from medicine to even residential home construction.

Supporters of 3D printing are quick to point out its educational value, where students can bring their digital designs into the physical world. The most straightforward educational uses for 3D printing align most closely with the so-called STEAM disciplines (science, technology, engineering, arts, and math), but there are a number of other fields, such as anthropology and history, where scholars are exploring its potential for both teaching and research.

However, my own experience with 3D printing is far more modest than, say, how some scientists are printing living cells. In fact, I’ve only successfully printed one thing in 3D: a small blue clover cup. Since then, I haven’t been able to replicate my success, which in fact was predicated by a number of failed attempts.

Changing Fate with a Screen: High School Live Cast in China

From MIT’s open courseware to the proliferation of Massive Open Online Courses (MOOC), I have seen a lot efforts being taken towards blending advancements in technology with the goodwill of making knowledge accessible to all. As an online learning professional, I have been following reports and research on the impact of open education, but never before have I been so stunned by the results of a report. The report, originally published in the weekly edition of Chinese Youth newspaper in Dec 12, 2018, was about a program that provides a full-day live broadcast of a prestigious high school to 248 high schools in the rural areas of China.  

Instead of listening to their own instructors, students in the rural or “far-end” high schools watch a live broadcast of instruction from a high school in Chengdu, the capital city of Sichuan province. According to the report, the launch of project faced strong resistance from teachers in these rural schools. They protested by tearing books apart. Some teachers even took a whole week off and left students “staring” at the screen by themselves.

Troubleshooting Common Videoconferencing Problems

With increasing technologies being used to facilitate global learning experiences (GLE) and guest participants in the classroom, technical difficulties are inevitable (as with any technology). Such unplanned technological mishaps often lie beyond the control of participants and instructors, so as with any collaborative effort to meet, it is best to prepare for common scenarios.

Consider the following scenario: You have invited a remote guest speaker in Germany for an hour-long class lecture. Since this lecture is a big deal due to the labor-intensive logistics planning (which include coordinating time zone differences, course scheduling, language coordination, appointments with the instructional technology support at your institution, and much emphasis for participation from your students), you are very much hoping that the videoconferencing tool you’ve selected will work. 

Despite your careful planning, testing, and prior use of the technologies at hand, sometimes, things just won’t work out. When things do not work out, here are some ways to save your videoconferencing event.

Augmented Reality, Korean Dramas, and Higher Education

You probably asking yourself what do augmented reality (AR)and Korean dramas have to do with each other? Well, in December 2018 Korea debuted a new drama on Netflix, Memories of Alhambra, which revolved around a groundbreaking AR game based on medieval battles in Alhambra. The main character of the drama, Yoo Jin Woo, is a CEO of an investment company that specializes in optical devices. One optical device he creates was a contact lens that allows users to interact with AR content. For Jin Woo, getting his hands on the next big AR game was imperative. This leads to a late night phone call from an AR game creator, Jung Se Joo, telling him they need to meet ASAP otherwise he might sell his game to Jin Woo’s competitor. This gets Jin Woo on plane to Granada, Spain, and thus begins his AR journey.

Review of the Best Free Quiz Games: Kahoot vs. Poll Everywhere Competitions

I’ve been using Kahoot for several years to create competitive quiz games like 21 blitz for my students. It’s a great tool for reviewing previously covered concepts and breaking up lectures with quick knowledge checks. So, when a colleague encouraged me to check out Poll Everywhere’s new Competitions feature, I was skeptical. I have students who literally cheer when I announce that it’s time for a Kahoot quiz. Even hard-to-impress faculty get caught up in the competition during workshops. They overthink their team names, agonize over answer choices, and trash talk their neighbors as points are tallied. I couldn’t possibly abandon Kahoot and run away with another quiz tool after everything we’ve been through, could I?

Imagining the Future with China: A Report of a Study Abroad Course

Riding on a train that whistled 217 miles per hour, sitting in a car that solely relied on solar power, wandering in a bookstore that had no cashiers on site, and viewing a trading system without currency and government involvement. Those were some of the adventures 13 students from DePaul experienced this winter break in a study abroad course called “Imagining the Future with China.”

Pairing “China” with “the Future” is an interesting idea. For a long time, China had been characterized by its ancient history and deeply rooted culture. It is one of the four most ancient civilizations in the world. It has a history of over five thousand years. Its cultural heritage has descended through eleven dynasties. It was not until two decades ago that China started to catch up on economic development. There are plenty of data to show its growth, but as a non-economist and someone who cannot handle numbers, I would use this GDP graph to demonstrate China’s astonishing takeoff:

Preparing for the Future When the Virtual is so Real

PS4 gaming consoleLike any mom of teens, I am trying to pull my 13-year-old son away from his game console and get him to try something that I think would benefit him for his growth—something like reading!

“But books are history,” Grant claimed. “And this…” he tilted his head toward the screen with his hands still fixated on the bat-shaped controller, “is the future.”

But, Grant, you see, history is…

READY STUDENT ONE? Risks and Rewards of VR and AR in the College Classroom

While I’ll beg your forgiveness for the obvious hype-train connection in my title to the release of the film READY PLAYER ONE, the film does raise many questions about the future of Virtual Reality (VR) and Augmented Reality (AR). For me, this question often comes up in the context of VR and AR in education, since my work as an Instructional Designer often means looking at new technologies that could change the way we go about the task of learning and teaching. Our office recently started a working group together with partners across the university to begin exploring what VR and AR in education could look like.
