MOOCs and the education revolution - Rebane's Ruminations

George Rebane

[This is the transcript of my 4jan13 KVMR commentary.? I last covered MOOCs in my 21aug12 post.]

Let?s consider higher education for bit tonight, especially its cost, relevance, and the impact of learning technologies on traditional ways of delivering education products.?? Our post-secondary education and its graduates are the national jewel that affects every American?s quality of life.? As a stake in the ground, consider that our population growth has slowed to under one percent per year, which still translates to adding almost 3M people annually.? With demographic lags, we currently pump out about 4M young people a year into our job markets.

Everyone knows that they will earn more, the more post-high school education they get.? And everyone is told they are college material, and are encouraged to borrow money and apply for scholarships to pay for college.? This encouragement has been so successful that outstanding student loans now amount to over $1T nationwide.? On the whole, it?s hard to see how much of this debt will be paid off given that many or most college students select majors that don?t teach marketable skills.? The Atlantic reports that ?53% of recent college grads are under- or unemployed?.

Distinguished professor Richard Vedder of Ohio University tells us, ?In 2009, spending by Americans for post-secondary education totaled $461B, an amount 42% greater than in 2000, after accounting for inflation. This $461B is the equivalent of 3.3% of total U.S. gross domestic product (GDP) and an amount greater than the total GDP of countries such as Sweden, Norway and Portugal.?, adding that? ??more than 17 million college graduates were ?underemployed? in 2008.??? For many college graduates ?Would you like fries with that?? is a recurring theme across the land.

Many educators and employers, especially those who can?t find enough qualified workers, tell us that not everyone needs to go into debt getting a mushy major.?? Most high school graduates are not ready for a college education, and would do much better for their careers by learning a marketable skill set that is confirmed by various accepted levels of certification.? And to do that, more and more young people and older workers needing to change careers are turning to online education and training courses.? The acronym to remember is MOOC ? massively open online course.

MOOCs are now being delivered by major universities like Harvard, MIT, Duke, and Stanford, and additionally through private companies like Udacity and Coursera, often founded by academics.? MOOCs are free and open to the masses, and cover a widening range of subjects from the sciences to liberal arts.? These online courses are taken by students from all over the world with tens of thousands attending a single course.

Most MOOCs don?t yet count for credit toward a degree, but that is also changing as methods are developed to allow students to take proctored exams.? Venture capitalists have taken an interest, and are now investing in for-profit education companies that deliver MOOCs.? The industry is still in its infancy, and, as reported in the 2jan13 WSJ, they are still looking for viable business models.? Some candidate models incorporate job placement services to students who successfully complete courses.

In the meanwhile, there is some pushback from college presidents, many of whom are paid in the multiple millions per year.? But I believe they will be swept aside as the demand for skilled workers dovetails with millions of people who want to upgrade their skills and get good paying jobs.? MOOCs and new automated learning technologies will rapidly obsolete exorbitantly expensive institutions with gleaming student unions sporting steam baths and climbing walls, huge athletic programs, managed by top-heavy administrative staffs, and offering feel-good fields of study that aren?t worth a warm bucket of spit on the job markets.

Recall the ancient teachers lecturing their eager students in the shade of a tree.? We look forward to thousands of teachers again teaching under the virtual trees of the internet, trees that can shade untold of thousands of students who will be more eager than ever to learn something useful.

My name is Rebane, and I expand on this and related themes on georgerebane.com where the linked transcript of this commentary is posted, and where such issues are debated extensively.? However these views are not necessarily shared by KVMR.? Thank you for listening.

How to Start Freelancing Your Web Designing

Ditching the 9 to 5 for a work from home career as a freelancer has become one of the most popular choices in recent years. If you?re skilled in web design or web development, it?s very easy to transition to running your own home business. Many companies need the professional services for their own websites and you can make a nice living as a designer with the right set up.

Start Freelance Web Design

An Easy Way to Set Up Your Design Business

Using WordPress as your CMS or content management system will allow you to design websites much easier and faster. ?Once you discover all the ins and outs of the system, you can do nearly anything with each site you design. ?It?s also possible to learn how to design your own themes or buy custom designed themes for each site you design.

It?s important that you show off your design skills with your own website, as well. ?You will need hosting to get you started and?Siteground web hosting?is a good choice with plenty of upgradable options. Choose a domain name to help brand your business and design your website not only to capture your target market, but also to show off the skills you bring to the table.

Make sure your own website uses WordPress and you use some of the design tricks you already know to give potential clients an idea of what you can do. ?Most of the work you will do can be outsourced, but the actual design will be up to you. ?This is your chance to show how much talent you have and how you can benefit others looking to hire your services.

Your Home Office

Another very important part of setting up your business is your home office. This part can be a bit difficult if you are transitioning from a corporate environment. Distractions at home can cut into your work time and they can cost you money. Make sure to set up your office in an area with little traffic, and if possible, a door you can shut. In addition, make sure to properly light your office, as it will help keep your energy up throughout the workday.

Finding Clients

With thousands of small businesses taking their business to the internet every year, it?s not hard to?find design work. Of course, if you decide to offer development services, you can increase your profits from each client. Before you can make any money, however, you need to find some clients. Here are a couple effective ways to advertise your new business.

1.?Pay Per Click Advertising
Most of your potential clients will search with Google, Yahoo or Bing for companies offering your services. By using the different PPC advertising programs, you can put your ad in front of your target market. It?s possible to set up your campaigns for a specific country, state or city, if you only plan to offer services locally.

2.?Business Relationships
Creating relationships with other internet businesses, such as SEO (search engine optimization) companies and advertising companies can help you gain a steady flow of business. As these companies take on clients, they may need your help redesigning their websites or creating a website from scratch. Many SEO and advertising firms outsource the design work, which is where your services fit in.

What Should You Offer?

As a web designer, you should only actually do the design work yourself. ?This is your specialty and when you choose to use the WordPress system for your design, you can offer a number of different design packages. ?Some packages can include specific plugins capable of sharing blog posts, creating a better foundation for SEO benefits and much more. ?It will be up to you to decide what you want to offer and you can offer more than just design services, if you have dependable people to outsource tasks, such as content writing and SEO work to.

Offering a variety of packages ranging from a small website to a large website with a full marketing and content package will help you cater to a larger audience. Some business will only need a few pages designed and won?t really need marketing services, but others will want a full package. Make sure to research other design and development companies in your area and set your prices competitively.

Becoming a freelance web designer?can provide a rewarding business you can run from home. Working from home comes with its own set of challenges, but with the tips above, you can make the transition much easier.

Africa's energy consumption growing fastest in world

Africa's energy demands are skyrocketing, but with 64 recent major discoveries of fuel deposits, it is in a good position to meet its needs.

By Mike Pflanz,?Correspondent / January 1, 2013

A worker is seen at an oil exploration site in Bulisa district, approximately 152 miles northwest of Kampala, the capital of Uganda. As Africa continues to develop, energy demands and production are growing.

As the sun sets over Africa each day, instead of flicking a light switch or heating up the oven, most people put a match to a kerosene lantern or a burning ember to a charcoal stove.?

Skip to next paragraph

' + google_ads[0].line2 + '
' + google_ads[0].line3 + '

Africa, home to 15 percent of the world?s population, consumes just 3 percent of the world's energy output, and 587 million people, including close to three-quarters of those living in Sub-Saharan Africa, still have no access to electricity via national grids.

But the situation is changing, and swiftly. At 4.1 percent growth, Africa?s per capita energy consumption is growing faster than anywhere else, driven by improved infrastructure, inward investment, and efforts to tackle corruption.

Meanwhile, in the last five years, there have been 64 major discoveries of potential new fuel supplies ??mostly oil and gas deposits. Of those, 13 were found in the first eight months of 2012 alone.

?The potential impact is ginormous,? says Bob McBean, former managing director of Dubai Natural Gas Company and now chairman of Wentworth Resources, an oil and gas exploration and production firm in Tanzania.

?It?s very, very exciting and it constantly puts me in mind of natural resource finds in the Gulf 20 years ago. Assuming everybody comes onto the same page in terms of financing and regulation, there?s no reason why there should be any national power shortages at all in the future,? he adds.

Holding Africa back

That ambition cannot be realized too soon.

Currently fewer than one in six rural Africans is connected to a national electricity supply. Even in the continent?s more developed nations, the situation is dire: 84 percent of Kenyans, 81 percent of Ugandans, and 65 percent of Sudanese are off the grid.

Using kerosene lanterns and charcoal cook stoves at home causes as many as 1.4 million premature deaths from respiratory illnesses, according to the World Health Organization. Chopping down trees to burn as fuel harms the environment more than coal-fired power stations.

?Using inefficient energy sources both in energy and economic terms continues to keep large sections of [Africa?s] population from the benefits of development,? said Aly Ngouille Ndiaye, Senegal?s minister of energy and mines.

The continent?s growth cannot be accelerated without addressing the lack of reliable energy supply on a continent clearly endowed with untapped fuel resources, he added.

Generators sap profits

Businesses desperate to be competitive in an increasingly global marketplace despair as bills to fuel and service generators clip several crucial percentage points off their profits.

There are significant moves to expand renewable energy production across Africa.?

Panetta allows general to retire as 3-star

WASHINGTON (AP) ? The Pentagon says Defense Secretary Leon Panetta has permitted a three-star Army general accused of bullying subordinates to retire without a demotion in rank.

A Pentagon spokesman, Navy Lt. Cmdr. Nate Christensen, says Lt. Gen. Patrick O'Reilly was placed on the retirement rolls Tuesday.

A Pentagon inspector general's investigation last year found that O'Reilly regularly yelled and screamed at subordinates, often in public, demeaned and belittled employees and behaved in such a way as to result in the departure of at least six senior staffers from the Missile Defense Agency during his time as its director.

Panetta determined that O'Reilly had met the basic standard for being allowed to retire without a loss in rank, which is that he "served satisfactorily" as a three-star.

Google Glass features 'still in flux', no plans to display advertising on device

Google Glass features 'still in flux', 'no plans' to display advertising

It's been a few months since we heard anything new about Google Glass -- fortunately, IEEE Spectrum has managed get a few questions answered by the project's lead, Babak Parviz. While noting that Google Now could be "very compelling" on the new hardware, he stopped short of saying that it would make an outing on the headset. There will, however, be a cloud-based API, which Parviz hopes will help to maintain a consistent user experience -- it's already been used to build both the email and calendar functions on Glass. Perhaps more importantly, when asked whether Google Glass would display advertising to its users, the project lead said that there were no plans for ads on the device. Google's keeping it vague with a precise feature list, but hardware-wise, Parviz says that the team is aiming for the headwear to last a full day on a single charge, with work still underway on head gestures -- still likely to be the least subtle input option alongside the (now patented) trackpad and voice commands. He added that the product is still on track to ship to those early 'explorers' early this year -- we're already polishing our glass block in anticipation.

(AP) ? Squarely in the spotlight, House Republicans prepared to meet Tuesday to decide their next move after the Senate overwhelmingly approved compromise legislation negating a fiscal cliff of across-the-board tax increases and sweeping spending cuts to the Pentagon and other government agencies.

In a New Year's Day drama that climaxed in the middle of the night, the Senate endorsed the legislation by 89-8 early Tuesday. That vote came hours after Vice President Joe Biden and Senate Republican Leader Mitch McConnell of Kentucky sealed a deal.

It would prevent middle-class taxes from going up but would raise rates on higher incomes. It would also block spending cuts for two months, extend unemployment benefits for the long-term jobless, prevent a 27 percent cut in fees for doctors who treat Medicare patients and prevent a spike in milk prices.

The measure ensures that lawmakers will have to revisit difficult budget questions in just a few weeks, as relief from painful spending cuts expires and the government requires an increase in its borrowing cap.

House Speaker John Boehner pointedly refrained from endorsing the agreement, though he's promised a vote on it or a GOP alternative right away. The exact timing of the vote was uncertain.

As the House began a rare New Year's Day session, it was clear that there were divisions among lawmakers from both parties.

Rep. James Moran, D-Va., called it "a bad deal for America." Rep. Jason Altmire, D-Pa., said approving it would "show the American people that this Congress isn't broken."

Rep. Darrell Issa, R-Calif., said that while he might vote for it, "I won't do it thinking we've accomplished anything here today, other than the smallest finger in a dike that in fact has hundreds of holes in it."

Boehner planned to brief his caucus early afternoon Tuesday. Biden entered a separate meeting with House Democrats to reprise his role of Monday night, when he promoted compromise to Senate Democrats before that chamber voted.

Boehner and House Majority Leader Eric Cantor, R-Va., arrived at the Capitol in late morning, and both bid "Happy New Year" to greeters but didn't say anything substantive about the Senate-passed bill.

One of the more conservative House Republicans, Rep. Tim Huelskamp, had no such reticence to speak.

"It's three strikes in my book and I'll be voting no on this bill," he told CNN Tuesday morning, saying the legislation would impose a hardship on small businesses around the country and falls short of addressing the need for cuts in spending.

The measure is the first significant bipartisan tax increase since 1990, when former President George H.W. Bush violated his "read my lips" promise on taxes. It would raise an additional $620 billion over the coming decade when compared with revenues after tax cuts passed in 2001 and 2003, during the Bush administration. But because those policies expired at midnight Monday, the measure is officially scored as a whopping $3.9 trillion tax cut over the next decade.

President Barack Obama praised the agreement after the Senate's vote.

"While neither Democrats nor Republicans got everything they wanted, this agreement is the right thing to do for our country and the House should pass it without delay," Obama said in a statement. "This agreement will also grow the economy and shrink our deficits in a balanced way ? by investing in our middle class, and by asking the wealthy to pay a little more."

The sweeping Senate vote exceeded expectations ? tea party conservatives like Pat Toomey, R-Pa., and Ron Johnson, R-Wis., backed the measure ? and would appear to grease enactment of the measure despite lingering questions in the House, where conservative forces sank a recent bid by Boehner to permit tax rates on incomes exceeding $1 million to go back to Clinton-era levels.

In the Senate, three Democrats and five Republicans voted against the legislation.

"Decisions about whether the House will seek to accept or promptly amend the measure will not be made until House members ? and the American people ? have been able to review the legislation," said a statement by Boehner and other top GOP leaders.

Lawmakers hope to resolve any uncertainty over the fiscal cliff before financial markets reopen Wednesday. It could take lots of Democratic votes to pass the measure and overcome opposition from tea party lawmakers.

Under the Senate deal, taxes would remain steady for the middle class but rise at incomes over $400,000 for individuals and $450,000 for couples ? levels higher than President Barack Obama had campaigned for in his successful drive for a second term in office. Some liberal Democrats were disappointed that the White House did not stick to a harder line, while other Democrats sided with Republicans to force the White House to partially retreat on increases in taxes on multi-million-dollar estates.

The measure also allocates $24 billion in spending cuts and new revenues to defer, for two months, some $109 billion worth of automatic spending cuts that were set to slap the Pentagon and domestic programs starting this week. That would allow the White House and lawmakers time to regroup before plunging very quickly into a new round of budget brinkmanship, certain to revolve around Republican calls to rein in the cost of Medicare and other government benefit programs.

Officials also decided at the last minute to use the measure to prevent a $900 pay raise for lawmakers due to take effect this spring.

Even by the dysfunctional standards of government-by-gridlock, the activity at both ends of historic Pennsylvania Avenue was remarkable as the administration and lawmakers spent the final hours of 2012 haggling over long-festering differences.

Republicans said McConnell and Biden had struck an agreement Sunday night but that Democrats pulled back Monday morning. Democrats like Tom Harkin of Iowa said the agreement was too generous to upper-bracket earners. Obama's longstanding position was to push the top tax rate on family income exceeding $250,000 from 35 percent to 39 percent.

"No deal is better than a bad deal. And this look like a very bad deal," said Harkin.

The measure would raise the top tax rate on large estates to 40 percent, with a $5 million exemption on estates inherited from individuals and a $10 million exemption on family estates. At the insistence of Republicans and some Democrats, the exemption levels would be indexed for inflation.

Taxes on capital gains and dividends over $400,000 for individuals and $450,000 for couples would be taxed at 20 percent, up from 15 percent.

The bill would also extend jobless benefits for the long-term unemployed for an additional year at a cost of $30 billion, and would spend $31 billion to prevent a 27 percent cut in Medicare payments to doctors.

Another $64 billion would go to renew tax breaks for businesses and for renewable energy purposes, like tax credits for energy-efficient appliances.

Despite bitter battling over taxes in the campaign, even die-hard conservatives endorsed the measure, arguing that the alternative was to raise taxes on virtually every earner.
