In our last <a href="https://blogs.worldbank.org/publicsphere/knowing-what-we-don-t-know-web" target="_blank" rel="nofollow">post</a> we showed you how to be reasonably confident that the information you find from an online resource is accurate, especially when you do not have the subject matter expertise to ascertain its correctness. In the next two blogs, we will take a closer look at educationational videos - arguably the “hottest” format for knowledge exchange.<br />  <br /> This is a pragmatic blog for providing technical knowledge to adult professionals. So we are not going to address big questions like: <ul><li> <a href="https://hackeducation.com/2011/07/19/the-wrath-against-khan-why-some-educators-are-questioning-khan-academy" target="_blank" rel="nofollow">Do they truly educate</a> or do they entertain you enough that you feel “educated?” (Hack Edcuation:<em>"<a href="https://hackeducation.com/2011/07/19/the-wrath-against-khan-why-some-educators-are-questioning-khan-academy" target="_blank" rel="nofollow">The Wrath Against Khan</a>”</em>)</li> <li> Are educational systems based on videos mostly about <a href="https://www.nytimes.com/2012/07/20/opinion/the-trouble-with-online-education.html?_r=0" target="_blank" rel="nofollow">selling the dream of education</a> rather than education itself? (New York Times:<em>“<a href="https://www.nytimes.com/2012/07/20/opinion/the-trouble-with-online-education.html" target="_blank" rel="nofollow">The Trouble With Online Education</a>”)</em></li> </ul> The debate rages on while the <a href="https://www.washingtonpost.com/news/answer-sheet/wp/2013/02/09/global-education-market-reaches-4-4-trillion-and-is-growing/" target="_blank" rel="nofollow">trillion dollar online education</a> industry blossoms.<br />  <br /> No matter which side of the aisle you are on in this big debate, if you are in the need to learn something useful (quickly) and you are choosing a web source to learn from- remember these five critical factors - and then decide whether to use a video or some other source. These factors may not guarantee the success of a learning session but ignoring them will most likely ensure the session’s failure.<br /><br /></div></div></div> Tue, 12 Jul 2016 16:06:00 +0000 Tanya Gupta 7456 at https://blogs.worldbank.org/publicsphere Media (R)evolutions: Now, computers can tell how you're feeling https://blogs.worldbank.org/publicsphere/media-revolutions-now-computers-can-tell-how-youre-feeling <div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><h4> New developments and curiosities from a changing global media landscape: People, Spaces, Deliberation brings trends and events to your attention that illustrate that tomorrow's media environment will look very different from today's, and will have little resemblance to yesterday's.</h4> <p> Imagine watching a commercial, and the TV or mobile phone on which you are watching immediately knows if you’d like to buy the product being advertised.  Imagine feeling stressed out while driving, and your car automatically starts talking to you and adjusting the air and radio controls.

Shifts in the texture of skin, such as wrinkles, are also tracked and combined with the information on facial points. Finally, the software identifies an expression by comparing it with those it has previously analyzed. <br /></div></div></div> Wed, 14 Oct 2015 16:29:00 +0000 Roxanne Bauer 7185 at https://blogs.worldbank.org/publicsphere The things we do: Stop multitasking and start focusing https://blogs.worldbank.org/publicsphere/things-we-do-stop-multitasking-and-start-focusing <div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><h4> Many believe that multitasking is the art of the productive. However, social science reveals that humans don't really multitask, but rather they rapidly switch among tasks. It's a cognitive illusion that actually results in less productivity and may harm the brain's natural abilities.</h4> <p> <img alt="caffeinating, calculating, computerating" height="175" src="https://blogs.worldbank.org/publicsphere/files/publicsphere/4453018910_613ea8d637_z.jpg" style="float:left" title="" width="280" />In June of this year, a <a href="https://www.scmp.com/news/china/society/article/1825111/its-ok-i-can-multitask-says-chinese-motorist-taking-intravenous" target="_blank" rel="nofollow">Chinese motorist was caught</a> driving while undergoing intravenous therapy and talking on the phone.  A needle providing the intravenous therapy was stuck in the back of his right hand, which had been holding his phone, while he used his left hand to hold the iron pole with the intravenous fluid bag and also the car’s steering wheel.  Police in the city of <a href="https://en.wikipedia.org/wiki/Wenzhou" target="_blank" rel="nofollow">Wenzhou</a> in southeastern <a href="https://en.wikipedia.org/wiki/Zhejiang" target="_blank" rel="nofollow">Zhejiang province</a>, China were on patrol on June 20 when they saw the motorist driving at 80km/h.<br /><br /> The driver told police he was rushing to carry out some urgent matters so had left a health clinic before his infusion was complete. He claimed that it was not dangerous for him to be driving at the time because he was good at multitasking. The police didn’t buy his multitasking defense and fined the driver 150 yuan and deducted four points from his driving license for dangerous driving and using a mobile phone while driving.<br /><br /> In a famous study of drivers chatting on mobile phones, <a href="https://psych.utah.edu/lab/appliedcognition/publications/cellphone.pdf" target="_blank" rel="nofollow">David Strayer and Frank Drews found</a> that diving while using a mobile phone is as dangerous as driving while drunk.<br /><br /> The problems of multitasking don’t end with driving.  Harvard Medical School knows first-hand that multitasking increases the number of mistakes people make— a resident doctor <a href="https://www.health.harvard.edu/blog/multitasking-a-medical-and-mental-hazard-201201074063" target="_blank" rel="nofollow">nearly killed a patient</a> after a text message distracted her from updating a prescription. <br /><br /> These and other examples point to an undeniable truth: multitasking can be dangerous at its worst and inefficient at its best. Even simple can produce a kind of ‘attention interference’ when performed simultaneously.</p> </div></div></div> Tue, 06 Oct 2015 15:56:00 +0000 Roxanne Bauer 7178 at https://blogs.worldbank.org/publicsphere The Things We Do: Bandwidth Poverty- When our Minds Betray Us https://blogs.worldbank.org/publicsphere/things-we-do-bandwidth-poverty-when-our-minds-betray-us <div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p> <img alt="" height="210" src="https://blogs.worldbank.org/publicsphere/files/publicsphere/Farmer_in_India.JPG" style="float:left" width="280" />Struggling to ‘get by’ is stressful.  We worry whether we can make it to our next paycheck, whether a trip to the market will be successful, whether we can pay the rent on-time… the list goes on.<br /><br /> All of this stress leads to an attention shortage, known as <a href="https://www.sciencemag.org/content/341/6149/976" target="_blank" rel="nofollow">bandwidth poverty</a>.  Bandwidth poverty creates a negative, reinforcing cycle.  When we experience financial poverty, we focus on the immediate need to make money or to pay a bill, and we don’t have sufficient cognitive resources or bandwidth to spend on other tasks or later deadlines. This leads to less-than-optimal decisions that leave us worse-off because we’ve lost the capacity or mental space to consider future needs.<br /><br /> In a <a href="https://www.sciencemag.org/content/341/6149/976#aff-1https://www.sciencemag.org/content/341/6149/976" target="_blank" rel="nofollow">series of experiments</a>, researchers from Harvard, Princeton and Britain's University of Warwick found that urgent financial worries had an immediate impact on poor people's ability to perform well in tests of cognition and logic.<br /><br /> The researchers conducted two sets of experiments— in two very different settings— one in a mall in suburban New Jersey and one involving sugar cane farmers in rural India.<br />  </p> </div></div></div> Tue, 15 Jul 2014 16:31:00 +0000 Roxanne Bauer 6759 at https://blogs.worldbank.org/publicsphere Think Accountability https://blogs.worldbank.org/publicsphere/think-accountability <div class="field field-name-body field-type-text-with-summary field-label-hidden"><div class="field-items"><div class="field-item even"><p><img class="" height="216" alt="" hspace="0" width="280" align="left" border="0" src="/files/publicsphere/image/brain.jpg" />As follow-up to <a onclick="window.open(this.href,'','resizable=no,location=no,menubar=no,scrollbars=no,status=no,toolbar=no,fullscreen=no,dependent=no,status'); return false" href="https://go.worldbank.org/6NKWHXJTF0">CommGAP</a>'s workshop &quot;<a onclick="window.open(this.href,'','resizable=no,location=no,menubar=no,scrollbars=no,status=no,toolbar=no,fullscreen=no,dependent=no,status'); return false" href="https://go.worldbank.org/9KFY1KLRD0">Generating Genuine Demand for Social Accountability Mechanisms&quot;</a> we're working on publishing an edited volume on this issue with <a onclick="window.open(this.href,'','resizable=no,location=no,menubar=no,scrollbars=no,status=no,toolbar=no,fullscreen=no,dependent=no,status'); return false" href="https://www.berkeley.edu/">Berkeley</a>-Professor <a onclick="window.open(this.href,'','resizable=no,location=no,menubar=no,scrollbars=no,status=no,toolbar=no,fullscreen=no,dependent=no,status'); return false" href="https://blogs.worldbank.org/publicsphere/user/taeku">Taeku Lee</a>.
