Bitcoin Georgia

How The Tiny Nation Of Georgia Became A Bitcoin Behemoth.

Georgia is now ranked second in the world for cryptocurrency mining — behind only China.

A single U.S.-based technology company called Bitfury has been accounting for much of this mining activity, from a vast data center filled with computer servers which it opened on the outskirts of the capital Tbilisi. It has generated plenty of controversy too over claims that it received overly generous terms for its electricity bills. But scores of smaller data centers have now sprouted up, with many more people mining from home with processors bought online from China.

making an average of $800 a month mining a currency called Zcash, with the extra electricity load costing about $80.

Bitfury has also been talking to the authorities in nearby Ukraine about using blockchain technology to run future elections there.

When supporters log on to its website, they are given the choice of allowing their computer processors to be used to mine Monero, a newer virtual coin being marketed for its extreme anonymity.

Facebook groups now regularly advertise conferences and gatherings to share ideas, addressed by people who call themselves “blockchain evangelists.”

Like the original Klondike, Georgia’s digital gold rush has attracted some colorful characters hoping to make their fortune.

Take Andrew Thornhill, an energetic financial entrepreneur from Chicago and founder of a cryptocurrency startup called Spotcoin. He first came to Georgia a decade ago to provide Internet-banking advice. In 2011, he was briefly imprisoned for fraud, but he says his conviction does not restrict him from running a financial business either there or in Georgia.

Concerns that cryptocurrencies are being used as a money-laundering vehicle have been overdone, Thornhill says when we meet at Spotcoin’s Tbilisi headquarters. “Criminals are using dollars and euros every day, but we don’t blame the currencies,” he says. And blockchain technology has the potential to make financial transactions far more secure, he maintains.

edtech implementation fails

5 All-Too-Common Ways Edtech Implementations Fail

By Chris Liang-Vergara and Kerry Gallagher (Columnist)     Apr 6, 2017

On the surface, adopting technology to support teacher needs or student challenges isn’t terribly complex: define the problem you’re trying to solve, identify the right tools for the job, and implement the tools effectively and with fidelity.

challenges. End users are too often removed from the decision-making process during procurement. Educators argue that too many products don’t actually meet the needs of teachers or students. Still others worry that it is too easy to implement new and popular technology without considering whether it is research-based and effective.

Only 33 percent of parents surveyed by the Learning Assembly said their child’s school did an excellent job using technology to tailor instruction.

  • Understanding Purpose

Technology is just a tool, not a means in and of itself. Any school or teacher that sets out to use technology for its sake alone, and not in the service of personalizing learning or addressing specific needs, is on a mission to fail.

  • Insufficient Modeling of Best Practices

A survey from Samsung found that 37 percent of teachers say they would love to use technology but don’t know how, and 76 percent say they would like a professional development day dedicated to technology.

ideos that focus on scaling and modeling best practices (produced by places like the Teaching Channel and The Learning Accelerator) can help teachers and schools do this.

  • Bad First Impressions

Teachers face initiative fatigue: They are constantly being asked to implement new programs, integrate new technologies, and add on layers of responsibility. In one Wisconsin district, nearly half of teachers felt ongoing district initiatives were a “significant area of concern.”

Forward-thinking schools take the time to learn from the challenges of other schools, and recruit a coalition of the willing.

  • Real-World Usability Challenges

Relying on multiple devices (remote, clicker, iPad, computer mouse) to launch or navigate technology can be difficult. Additionally, teachers may start to use a tool, only to realize it is not flexible enough to meet their original needs, fit into the constraints of their particular school or classroom, or allow them to integrate their own content or supplemental resources.

  • The Right Data to Track Progress

Lack of useful data, problem definition, weak teacher buy-in, first impressions, and usability challenges all have the potential to torpedo smart technology products.

Beyond the Hype: 5 Ways to Think About Virtual and Augmented Reality in Schools

By Jenny Abamu     Feb 7, 2017

https://www.edsurge.com/news/2017-02-07-beyond-the-hype-5-ways-to-think-about-virtual-and-augmented-reality-in-schools

1. Ask Yourself: Why VR or AR

AR and VR are mediums for the transmission of information, and many people will judge these mediums by the content that is produced within them. For educators seeking to gain buy-in from administrators and other colleagues it is critical for them to justify the reasons their content requires new reality media.

2. Just Dive In

Gartner Hype Cycle’s “slope of enlightenment”—meaning the technology is just entering public acceptance.

Given the newness of these mediums, it is no surprise that few curricular resources exist to support courses around VR and AR. Professional development sessions on new reality tools are almost non-existent, which means educators seeking to use virtual or augmented reality simply need to dive into the subjects.

3. Go Beyond Storytelling

Studies using VR demonstrate the ‘Proteus Effect’—taking on the psychology of inhabiting a different body and unconsciously changing our behavior to conform to it (learning empathy through VR)

4. Master the Machines

“The equipment matters. If there is a latency between the computer and the VR set that can cause a lot of problems,”
With VR equipment ranging from about $15 to $600 educators will have to check the budget or start writing grant proposals to gain access to the higher quality machines.

5. Understand Your Student’s Needs

described as a “quantum shift” in the way we interact, learn and experience.

Edtech playground: Helping teachers choose better tools

By Nicole Krueger Leadership

https://www.iste.org/explore/articleDetail?articleid=2177

A virtual reality headset can take students on an immersive journey to another world. But no matter how cool it is, if that $3,000 piece of equipment enters a classroom and doesn’t provide any real instructional value, it can quickly become a very expensive paperweight.

Most schools don’t do edtech procurement really well yet. Sometimes we buy products that end up in closets because they don’t fit the instructional needs of students, and we end up not being good stewards of taxpayer dollars.

Located in the district’s central office, where hundreds of teachers and staff members stop by each week for professional development, the playground offers a creative space that encourages teachers to explore new tools that have been vetted and approved by the district’s tech department.

In the United States, K-12 schools spend more than $13 billion a year on edtech — often without any idea whether it will make a difference in learning outcomes.

ABSTRACT
The Augmented Reality Game, Pokemon Go, took the world by storm in the summer of 2016. City landscapes were decorated with amusing, colourful objects called Pokemon, and the holiday activities were enhanced by catching these wonderful creatures. In light of this, it is inevitable for mobile language learning researchers to reflect on the impact oft his game on learning and how it may be leveraged to enhance the design of mobile and ubiquitous technologies for mobile and situated language learning. This paper analyses the game Pokemon Go and the players’ experiences accordingto a framework developed for evaluating mobile language learning and discusses how Pokemon Go can help to meetsome of the challenges faced by earlier research activities.
A comparison between PG and Geocashing will illustrate the evolution of the concept of location-based games a concept that is very close to that of situated learning that we have explored in several previous works. 
Pokémon Go is a free, location-based augmented reality game developed for mobile devices. Players useGPS on their mobile device to locate, capture, battle, and train virtual creatures (a.k.a. Pokémon), whichappear on screen overlaying the image seen through the device’s camera. This makes it seem like thePokemon are in the same real-world location as the player
“Put simply, augmented reality is a technology that overlays computer generated visuals over the real worldthrough a device camera bringing your surroundings to life and interacting with sensors such as location and heart rate to provide additional information” (Ramirez, 2014).
Apply the evaluation framework developed in 2015 for mobile learning applications(Cacchione, Procter-Legg, Petersen, & Winter, 2015). The framework is composed of a set offactors of different nature neuroscientific, technological, organisational and pedagogical and aim to provide a comprehensive account  of what plays a major role in ensuring effective learning via mobile devices
