Newly Discovered Protein Function Linked to Breast Cancer | UANews.org - 9 views

  • he researchers report their findings in the advance online publication of the Nature Cell Biology July issue. The cells in our bodies constantly sense their environment and respond appropriately. For example, if pathogens invade the body, cells will respond by generating an inflammatory environment to fight the pathogen. This is achieved by intricate molecular circuits within cells that sense and relay external signals and orchestrate the cellular response. Aberrant functioning of these cellular switch boards can lead to diseases including autoimmune disorders and cancer. In the study, an the scientists set out to better understand the molecular workings underlying inflammation. Inflammation, the body's primary line of defense against disease-causing microbes and parasites, is a highly complex and tightly regulated biochemical process involving a myriad of specialized cells communicating with each other through an arsenal of signaling molecules.

The Code of Best Practices in Fair Use for Media Literacy Education - 60 views

  • when they occur within a restricted-access network, do enjoy certain copyright advantages
  • we as a society give limited property rights to creators to encourage them to produce culture; at the same time, we give other creators the chance to use that same copyrighted material, without permission or payment
  • Did the unlicensed use "transform" the material taken from the copyrighted work by using it for a different purpose than that of the original, or did it just repeat the work for the same intent and value as the original? • Was the material taken appropriate in kind and amount, considering the nature of the copyrighted work and of the use?
  • ...21 more annotations...
  • If the answers to these two questions are "yes," a court is likely to find a use fair
  • whether the use will cause excessive economic harm to the copyright owner
  • the purpose of copyright—to promote the advancement of knowledge through balancing the rights of owners and users.
  • In some cases, this will mean using a clip or excerpt; in other cases, the whole work is needed. Whenever possible, educators should provide proper attribution and model citation practices that are appropriate to the form and context of use.
  • educators should provide reasonable protection against third-party access and downloads
  • educators using concepts and techniques of media literacy should be free to enable learners to incorporate, modify, and re-present existing media objects in their own classroom work
  • Students’ use of copyrighted material should not be a substitute for creative effort
  • Students should be able to understand and demonstrate, in a manner appropriate to their developmental level, how their use of a copyrighted work repurposes or transforms the original.
  • but cannot rely on fair use when their goal is simply to establish a mood or convey an emotional tone, or when they employ popular songs simply to exploit their appeal and popularity
  • material that is incorporated under fair use should be properly attributed wherever possible
  • attribution, in itself, does not convert an infringing use into a fair one.
  • If student work that incorporates, modifies, and re-presents existing media content meets the transformativeness standard, it can be distributed to wide audiences under the doctrine of fair use.
  • When sharing is confined to a delimited network, such uses are more likely to receive special consideration under the fair use doctrine
  • there are no cut-and-dried rules (such as 10 percent of the work being quoted, or 400 words of text, or two bars of music, or 10 seconds of video).
  • Transformativeness, a key value in fair use law, can involve modifying material or putting material in a new context, or both
  • Copyright Act itself makes it clear that educational uses will often be considered fair because they add important pedagogical value to referenced media objects.
  • If educators or learners want to share their work only with a class (or another defined, closed group) they are in a favorable position
  • if work is going to be shared widely, it is good to be able to rely on transformativeness
  • courts have found that asking permission and then being rejected has actually enhanced fair use claims.
  • We don’t know of any lawsuit actually brought by an American media company against an educator over the use of media in the educational process
  • Lack of clarity reduces learning and limits the ability to use digital tools. Some educators close their classroom doors and hide what they fear is infringement; others hyper-comply with imagined rules that are far stricter than the law requires, limiting the effectiveness of their teaching and their students’ learning.

The Wired Campus - Duke Professor Uses 'Crowdsourcing' to Grade - The Chronicle of High... - 0 views

  • Learning is more than earning an A says Cathy N. Davidson, the professor, who recently returned to teach English and interdisciplinary studies after eight years in administration. But students don't always see it that way. Vying for an A by trying to figure out what a professor wants or through the least amount of work has made the traditional grading scale superficial, she says.
  • "Do all the work, you get an A. Don't need an A? Don't have time to do all the work? No problem. You can aim for and earn a B. There will be a chart.  You do the assignment satisfactorily, you get the points.  Add up the points, there's your grade. Clearcut. No guesswork. No second-guessing 'what the prof wants.' No gaming the system," Ms. Davidson wrote Sunday in a blog post detailing her strategy on hastac.org (pronounced "haystack"), the acronym for  "humanities, arts, science, and technology-advanced collaboration.," which she co-founded.
  • It's important to teach students how to be responsible contributors to evaluations and assessment. Students are contributing and assessing each other on the Internet anyway, so why not make that a part of learning?"

  • Programming -OK, on the programming thing, here are my thoughts.In our curriculum our objective is not as much a specific LANGUAGE. One year I may use HTML with Javascript, this past year I used LSL — what I want kids to know that when they encounter programming and coding that there are certain conventions. Some are case sensitive, some are not. How do you find out how to add to what you know about programming? Do you know where to go to find prewritten code? Can you hack it to make it work to do what you want it to do?We spend about a week – two weeks but I require they know how to handcode hyperlinks and images – they are just too important.But to take 12 weeks or 6 weeks to learn a whole language – yes maybe some value – but to me the value is HOW is the language constructed or built. What are the conventions and how do I educate myself if I am interested in pursuing. What comes out of this time is kids who say either “I never want to do that” or “this is really cool, I love coding.”They are doing very simplistic work (although the LSL object languages were pretty advanced) but since we don’t have a full course nor time in our curriculum, I do see this as an essential part of what I teach.I’m not teaching it for the language sake but for the sake of understanding the whole body of how languages work – we talk about the different languages and what they are used for as part of Intro to Computer science and have an immersive experience.To me, this is somewhat a comprimise between leaving it out entirely or forcing everyone to take 12 weeks of it. I just don’t know where 12 weeks would go in the curriculum.

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.

News: The 'Prior Learning' Edge - Inside Higher Ed - 15 views

  • An examination of the educational records of more than 62,000 adult undergraduates at 48 colleges finds that students who had sought and been awarded academic credit by their institutions for "prior learning" earned in the military, corporate training and other non-classroom settings were more than twice as likely to graduate, and to persist even if they did not graduate, than were their peers who had not earned such credit.
  • “CAEL’s research confirms that prior-learning assessment can help adults move faster toward their associate’s and baccalaureate degrees. We need to see more institutions offering this option and more adults participating in it.”
  • The concept of "prior learning assessment" is decades old, and it has grown to include multiple types of mechanisms for measuring knowledge and skills that students have accumulated through various types of formal and less formal formats, such corporate training, work experience, and independent study. The most common types of assessments include standardized exams developed by the College Board (the College Level Examination Program exams and Advanced Placement exams), the American Council of Education's guides for recognizing credit for instructional programs offered in the military and by employers, and institutional reviews of individualized student portfolios.

  • credit awarded through prior learning assessments offers an opportunity to entice adults back to college with the prospect that they can build on learning they've already gained and reduce both the time and money they might have to expend to earn a credential.
  • "Do PLA students have higher graduation rates because PLA enhances the self-esteem and motivation of students by showing them that they have already mastered college-level learning? Is it also because PLA students already possess characteristics that are associated with better academic outcomes? What institutional policies are influencing whether and how students are using (or not using) PLA, and whether or not this helps them achieve a shorter time to degree?"

HASTAC | Humanities, Arts, Science, and Technology Advanced Collaboratory - 39 views

  •  
    HASTAC ("haystack") is a network of individuals and institutions inspired by the possibilities that new technologies offer us for shaping how we learn, teach, communicate, create, and organize our local and global communities. We are motivated by the conviction that the digital era provides rich opportunities for informal and formal learning and for collaborative, networked research that extends across traditional disciplines, across the boundaries of academe and community, across the "two cultures" of humanism and technology, across the divide of thinking versus making, and across social strata and national borders.

Few Students Show Proficiency in Science, Tests Show - NYTimes.com - 18 views

  • Only one or two students out of every 100 displayed the level of science mastery that the department defines as advanced
  • a smaller proportion of American 12th graders demonstrated proficiency in science than in any other subject that the federal government has tested since 2005 — except history
  • Twenty-one percent of the nation’s 12th graders scored at or above the proficient level in science on the 2009 tests, compared with 42 percent who demonstrated proficiency on the most recent economics exam, and 38 percent and 26 percent, respectively, on the most recent nationwide reading and math tests.
