Tinkering with Old Technology - The Learner's Way - 27 views

  •  
    As technology evolves and its inner workings increasingly disappear from view, replaced with solid-state parts hidden by glass, aluminium and plastic, our understanding of what makes the world operate is similarly impeded. When machinery from just a few decades ago is viewed a world of moving parts, linkages, cogs and levers is revealed. These mechanical objects contain an inherent beauty and inspire curiosity in ways that modern devices with their pristine surfaces and simplified design language do not. Opportunities to explore devices from the past open our eyes and lead us to new questions of how our devices function, how machines do the jobs we need them to do and how engineers solve problems.

Semi-automatic method for grading a million homework assignments - O'Reilly Radar - 34 views

  •  
    The above figure is the landscape of ~40,000 student submissions to the same programming assignment on Coursera's Machine Learning course. Nodes represent submissions and edges are drawn between syntactically similar submissions. Colors correspond to performance on a battery of unit tests (with red submissions passing all unit tests). In particular, clusters of similarly colored nodes correspond to multiple similar implementations that behaved in the same way (under unit tests).

Basic item analysis for multiple-choice tests. Kehoe, Jerard - 1 views

    Basic Item Analysis for Multiple-Choice Tests. Jerard Kehoe, Virginia Polytechnic Institute and State University This article offers some suggestions for the improvement of multiple-choice tests using "item analysis" statistics. These statistics are typically provided by a measurement services, where tests are machine-scored, as well as by testing software packages. The basic idea that we can capitalize on is that the statistical behavior of "bad" items is fundamentally different from that of "good" items. Of course, the items have to be administered to students in order to obtain the needed statistics. This fact underscores our point of view that tests can be improved by maintaining and developing a pool of "good" items from which future tests will be drawn in part or in whole. This is particularly true for instructors who teach the same course more than once.

Digital Domain - Computers at Home - Educational Hope vs. Teenage Reality - NYTimes.com - 32 views

  • Economists are trying to measure a home computer’s educational impact on schoolchildren in low-income households.
  • little or no educational benefit is found. Worse, computers seem to have further separated children in low-income households, whose test scores often decline after the machine arrives, from their more privileged counterparts.
  • few children whose families obtained computers said they used the machines for homework. What they were used for — daily — was playing games.

  • “Scaling the Digital Divide,” published last month, looks at the arrival of broadband service in North Carolina between 2000 and 2005 and its effect on middle school test scores during that period. Students posted significantly lower math test scores after the first broadband service provider showed up in their neighborhood, and significantly lower reading scores as well when the number of broadband providers passed four.
  • The expansion of broadband service was associated with a pronounced drop in test scores for black students in both reading and math, but no effect on the math scores and little on the reading scores of other students.
  • THE one area where the students from lower-income families in the immersion program closed the gap with higher-income students was the same one identified in the Romanian study: computer skills.
  • How disappointing to read in the Texas study that “there was no evidence linking technology immersion with student self-directed learning or their general satisfaction with schoolwork.”

Lines on Plagiarism Blur for Students in the Digital Age - NYTimes.com - 12 views

  • But these cases — typical ones, according to writing tutors and officials responsible for discipline at the three schools who described the plagiarism — suggest that many students simply do not grasp that using words they did not write is a serious misdeed.
  • Digital technology makes copying and pasting easy, of course. But that is the least of it. The Internet may also be redefining how students — who came of age with music file-sharing, Wikipedia and Web-linking — understand the concept of authorship and the singularity of any text or image.
  • “When you’re sitting at your computer, it’s the same machine you’ve downloaded music with, possibly illegally, the same machine you streamed videos for free that showed on HBO last night.”

  • Ms. Brookover, who works at the campus library, has pondered the differences between researching in the stacks and online. “Because you’re not walking into a library, you’re not physically holding the article, which takes you closer to ‘this doesn’t belong to me,’ ” she said. Online, “everything can belong to you really easily.”
  • Ms. Blum argued that student writing exhibits some of the same qualities of pastiche that drive other creative endeavors today — TV shows that constantly reference other shows or rap music that samples from earlier songs.

Making Oil from Plastic - 34 views

  • Making Oil from Plastic
  • Tons of plastic from Japan and US is left afloat in the Pacific Ocean, which is endangering marine life significantly.
  • Blest, a Japanese company has invented a safe and user friendly machine
  • ...3 more annotations...
  • The machine is effective in recycling different kinds of plastic into oil.
  • Utilization doesn't just take into account the 20 percent of recycled plastic. But it also considers the incinerated 52 percent used for energy recovery like generating electric power or heat. Akinori Ito says "If we burn the plastic, we generate toxins and a large amount of CO2. If we convert it into oil, we prohibit CO2 production and at the same time, increase people's awareness about the value of plastic garbage"
  • Oil from Shale: Oil can be extracted from this fine grained, organic rich, sedimentary rock through pyrolysis, thermal dissolution or hyderogentation. Shale contains high concentrations of organic chemical compounds known as Kerogen. From this solid mixture, oil is extracted through chemical process. Shale can be effective converted into combustible oil shale gas and liquid hydrocarbons (shale oil). Global deposits of Shale are estimated to be around 2.8 trillion to 3.3 trillion barrels of restorable oil. Planet earth is blessed with about 600 known oil shale deposits, most of which is found in United States of America. Although several countries have oil hale deposits, known deposits of economic importance is found only in 33 countries.

A Textbook Example of What's Wrong with Education | Edutopia - 0 views

  • A Textbook Example of What's Wrong with Education A former schoolbook editor parses the politics of educational publishing.by Tamim Ansary var addthis_options = 'delicious, digg, facebook, google, reddit, stumbleupon, twitter, more'; Print Forward addthis_pub = 'glef'; Share Comments(38) Comment RSS Click to enlarge pictureThe Muddle Machine Credit: Monte Wolverton Some years ago, I signed on as an editor at a major publisher of elementary school and high school textbooks, filled with the idealistic belief that I'd be working with equally idealistic authors to create books that would excite teachers and fill young minds with Big Ideas. Not so. I got a hint of things to come when I overheard my boss lamenting, "The books are done and we still don't have an author! I must sign someone today!" Every time a friend with kids in school tells me textbooks are too generic, I think back to that moment. "Who writes these things?" people ask me. I have to tell them, without a hint of irony, "No one." It's symptomatic of the whole muddled mess that is the $4.3 billion textbook business. Textbooks are a core part of the curriculum, as crucial to the teacher as a blueprint is to a carpenter, so one might assume they are conceived, researched, written, and published as unique contributions to advancing knowledge.
