Troubleshooting
Projector: Why does the image display on my laptop but not through the projector?
If the image displays on your laptop but not on the projection screen, you must activate the external display.  Doing so tells the computer that it should output its display to the screen.  To activate the external display, press and hold the “Function” key on your keyboard (usually to the left of the Space Bar and labeled “Fn”) while simultaneously pressing the appropriate “F-key” along the top of your keyboard. Below are some common F keys by vendor:
I-pad
Rebooting: Rebooting means to restart the app, wi-fi, and/or the iPad. Turning the device or app off and back on is like sleeping for the devices, and it solves more than half of the problems that arise. There is a difference between closing an app and turning it off. Closing involves pressing the home button or going to another app, while turning it off requires double pressing on the home button and swiping up on the app that you wish to close. Locking the device by pressing the power button once is also different from turning the device off by holding the power button for approximately 3 seconds. Make sure to reboot by turning off the apps and iPad.
Connecting a Windows-based laptop to the LCD projectors
Before you begin, make sure the projector and laptop are turned off, and connect the VGA cable. This is the cable which is connected to the cabinet. Connect the other end of cable to the laptop's VGA (monitor) port. Tighten the screws on both connectors to make sure they are fastened securely.
Connect ethernet cable to access the Internet if desired. Turn on projector before turning on your laptop. If computer image does not show on screen, press either Fn+F7, Fn+F5, or Fn+F8. The correct key combination will depend on your laptop's manufacturer and model, and may still be a different combination than those listed here.
Connecting an Apple laptop to the LCD projectors
Before you begin, make sure the projector and laptop are turned off. Connect the VGA cable. This is the cable which is connected to the cabinet. Connect the other end of cable to the laptop's VGA (monitor) port. Tighten the screws on both connectors to make sure they are fastened securely. (You will likely need an adapter to connect the VGA cable to your laptop. Classroom Support DOES NOT supply these)
Connect ethernet cable to access the Internet if desired. Turn on projector before turning on your laptop. Open the control panel on the laptop. Select monitor. Set monitor to mirror. This will enable you to see the image on both your computer screen and the LCD projector.
No Sound
There are so many reasons why sound stops working. Usually it’s one of three issues: 1) Volume is muted, so unmute it. A cousin to that is that many times, the volume is low, so all you have to do is turn it up. 2) Headphones are plugged in, which means you can’t hear sound through the speakers. Unplug them. 3) The computer bumped sound out of the operating queue. Maybe your system resources are low. Who knows. All you have to do is reboot.
I Erased My Document/Text
This is where I am a hero for at least a day -- maybe longer. Sometimes, students highlight their 20-page document to change margins (or who knows what) and accidently delete the entire document. No worries. Ctrl+Z (hold Ctrl and then push Z) will bring it back. That Undo shortkey goes back 200+ steps in case it happened a long time ago.
Keyboard Doesn’t Work
Anytime a piece of computer hardware appears to not work, I check first. With the keyboard, push Num Lock on the right side. If the Num Lock light goes on/off, the keyboard is working. If it doesn’t, replug cord into back of tower or reboot. Most of the time, that’ll fix it. Sometimes, your keyboard really is broken and you need a new one.
Mouse Doesn’t Work
Like with the keyboard, check it first. Move it around to see if the cursor moves. If it doesn’t, do the same as you did for the keyboard -- replug cord into back or reboot

App Practice: Inclusive

           No comments   

  The world is changing constantly, and people have felt plenty of anxiety because of the uncertainty of their future. I was born in 1981 and was called Gen Y.  Generation Y (born after 1980) are digital native generation transforming traditional communication to whole new era of technology. I was so grateful that I knew how to enjoy life without machines, I enjoyed the wind, the sun, the ocean, Music, and even the dirt. 

 For past 10 years, I refused to use any of apple company products, any apps, smart TV, and ETC though I had enough money to buy them. My idea was so simple, "live naturally, don't add artificial flavors in your life."

  However, before I recognize, the changes of the world have suppressed way beyond my knowledge. I tried to ignore the speed of these new technologies by not giving any interest. But as soon as I entered Gordon college for education, it was obvious that I should not avoid the fact of reality; it is 21st century, and it is critical for new generation adapting technology to their education environment.  We have to prepare for the massive unemployment sweeping the country by the artificial intelligence-based system society. We need courage to face this unfamiliar environment of future.
Educators have to try hard to predict or at least have a sense for the changes to come in near future for our students. If we are teaching some information that students can simply type in google search and figure it out, their times to learn something valuable for their future might be wasted. I'm not saying all those basic skills are not important, but teachers should be more flexible using positive effect of technology in their classroom. One of the positive effect of technology integrated classroom is that it can be much more inclusive environment.

 As an ELS student myself, I could express better, and learn more using apps that I've learned through this Edu 614 class. Like wings to fly exploring the world, every app and lessons that I've practiced through the class provided me a great view of possibility of near future education. From a basic skill of Google doc with Google slide to Fulbaroo, Edshelf and more, I want to introduce them for my students who are having a hard time to express themselves.  For students who have physical and mental limitations, assistant technologies will be provided to improve the functional capabilities so that they can feel much comfortable to communicate.

one of my favorite youtube channel is Special books by Special kids.  Every child has a different story and whenever I learn about the limitation they have, I try to figure out any tool or technology that they might need to achieve their goals. For this specific assignment, I want to focus on devices for blind or visually impaired people. 
Here is a story of a computer programmer who is actually blind. He explain how he has been studied and using technologies to learn. 
<Click here to see the ted video by Austin Seraphin>


 APH (American Printing House) is one of the nonprofit organization creating educational environment for blind people.  They sell products like the Orbit Braille 20 for reading, or Graphit for graphs. 
Two most important devices for visually impaired students need are alternative input devices like touch screens, modified keyboards, and joysticks, which can direct senses, or Speech-to-text apps for writing. 

 Facebook and google also updated their iOS apps to provide more inclusive environment for visually impaired people, more study about this section required.

Will AI Revolution Lead to Mass Unemployment?

 / T
BY JOHN BARNETT
April 24, 2017

Artificial Intelligence-based systems and chatbots are taking every industry by storm. As much as they are playing an important role in making tasks and processes better, their effect on human-centered jobs and capabilities in the workplace has become a major debate.
Artificial intelligence-based systems and chatbots are taking every industry by storm. As much as they are playing an important role in making tasks and processes better, their effect on human-centered jobs and capabilities in the workplace has become a major debate. The jobs that most of the people are currently doing, may get obsolete or automated sooner than you think.
A few months ago, a statement from Elon Musk broke the Internet, where he said AI-powered systems and automation technologies are going to replace most human jobs very soon. He also suggested that all countries may have to adapt universal basic income programs for their citizens to cope with the aftermath of this revolution. 
At this time, we all need tech enthusiasts and language programmers to create algorithms that automate the processes. Even the AI systems are based on languages and programs coded by humans and designed by humans. However, this is where AI has an edge. An AI-powered system has an ability to reach a singularity point where it becomes able to program itself, learn itself and implement itself. At this point, what role will humans play?

Is AI there to replace human jobs eventually?

This bold step has already been taken by Fukoku Mutual Life Insurance in Japan. The company stated that by the end of March, 34 of its employees will be replaced with an artificial intelligence system that can calculate payouts on policyholders. Although this may look like just a tiny cost-cutting technique by a company, it has a much deeper impact. It raises the question of what will happen to the future of employment.
From the perspective of a company, a computer does not look forward to a handsome paycheck at the end of every month; however, having a computer to work for you is not free either. To hire a computer as your employee, you have to bear development costs and also compare that cost with the total amount you would eventually be saving. Fukoku Life Insurance brought in an AI which costed them £1.4m, but the company's experts say that it would be saving £1m yearly. In addition to just the development and procurement costs, like any other machine, your AI would also need routine and unplanned maintenance. The company reported it costs about £100k a year.
The figures look good from a financial perspective, but many questions still need to be answered. Most important (from a company’s point of view) is the quality of a product, especially because the company is a service provider, and their product is not a tangible commodity. Whether AI can give a satisfactory quality of service or not must be the deepest concern for service companies. Would programmers be able to code the compassion into the machine? This can also be a debate.
However, there is another factor: the social acceptance of the fact that a person would lose a job every time a machine is assigned to perform his or her task. The growth of human jobs with the increase in AI-based platforms is not that significant, which might raise a few eyebrows. Soon, we can expect a number of organizations emerging from the need to regulate this change. Also, we are likely to face greater resistance from the people who are at the risk of losing their jobs.

Which jobs are vulnerable to AI revolution?

In a widely acclaimed study, Carl Benedikt Frey and Michael Osborne found out the probability of automation for 702 jobs, and found that 47 percent of employees in America are at high risk of losing jobs because of automation and AI. Their study warned the employees working in transport and logistics (taxi drivers and courier drivers are to be replaced by self-driving cars and car-pools), office support staff (security guards and front-desk officers to be replaced by computerized check-ins and securities), and sales and customer support staff (cashiers, telemarketers, call-center assistants, clerks are to be replaced with chatbots and machines).
The study also stated that “recent developments in machine learning and artificial intelligence will put a substantial share of employment, across a wide range of occupations, at risk in the near future.” Some other studies also noted an equivalent figure of 35 percent for the workforce for the United Kingdom (where more people work in creative industries less susceptible to automation) and 49 percent for Japan.

How does the future look?

Are we heading towards a future where automation will make employment a scarcity? "We are expecting 500 billion objects to become connected to the Internet, and this automation is going to hollow out middle and working class jobs," explained Jane Fraser, CEO of Citigroup's Latin America business, while speaking at Fortune's Most Powerful Women Summit in Laguna Niguel, Calif.  
But this is just one side of the story. AI will also create new jobs in the field. Self-driving cars may need drivers for emergency rides. More tech developers to create chatbots for every industry and most of all more AI-trainers to train chatbots to act like a human. Like websites, all the systems needs to be maintained and constantly updated. No matter how advanced and super-efficient AI may become, some jobs are always done better by humans, including doctors, therapists, hairdressers and personal trainers. An analysis of the British workforce by Deloitte highlighted a profound shift over the past two decades towards “caring” jobs: the number of nursing assistants increased by 909 percent, teaching assistants by 580 percent and care workers by 168 percent.
On one side, there are techies who say that machines and AI are ready to take all the jobs. On the other side, there are economists who say that AI revolution or any new technology always create more jobs than they destroy. Well, the real answer lies somewhere in between. Artificial Intelligence will not lead to mass unemployment, but it will shake up the foundation of many companies that rely on outdated technologies, which will result in huge losses and then layoffs. Those companies that will embrace it, will disrupt the industry and speed up the existing trend of computer-related automation which will enable their employees to learn new skills more quickly than in the past.

Assessment for 21st century


Assessment for 21st century should be comprehensive, and various sources and techniques are required. Assessment itself need to be authentic learning experiences for students that it can be expanded not just a test to check their knowledge by teachers but a technology enhanced tool for their personal learning strategy with instant feedback by peers or by themselves. So the formative assessment is a big part of learning environment in 21st century education.
