Magnet - Wikipedia, the free encyclopedia - 11 views

    • Sreedharen Sasidharen
       
      What is it?
  • A magnet (from Greek μαγνήτις λίθος magnḗtis líthos, "Magnesian stone") is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.
  • Ferromagnetic materials can be divided into magnetically "soft" materials like annealed iron, which can be magnetized but do not tend to stay magnetized, and magnetically "hard" materials, which do. Permanent magnets are made from "hard" ferromagnetic materials such as alnico and ferrite that are subjected to special processing in a powerful magnetic field during manufacture, to align their internal microcrystalline structure, making them very hard to demagnetize. To demagnetize a saturated magnet, a certain magnetic field must be applied, and this threshold depends on coercivity of the respective material. "Hard" materials have high coercivity, whereas "soft" materials have low coercivity.

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.

    Assessment | News Varsity Tutors Debuts Free Test Question Site By Dian Schaffhauser 11/07/13 Varsity Tutors, a providor of private tutoring to students online, has launched a new, free service with the intention of becoming the "Khan Academy" of practice tests. The company has introduced a Web-based assessment system intended to replace other forms of educational content such as SAT or ACT preparation books or online subscriptions to assessment materials. Varsity Learning Tools, as it's called, makes hundreds of free practice tests available in 95 subjects. Currently in open beta testing, the site lists assessment tests by subject and allows the user to choose to answer a single test, flashcards, or a question of the day. Each question can be shared through social network services. When the student answers it, a second page displays with an assessment and explanation and data on how much time was spent on the question, and how many others answered it correctly."

Department of Psychology :: Principles of Learning :: University of Memphis - 62 views

  • The single most important variable in promoting long-term retention and transfer is "practice at retrieval"
  • -learners generate responses, with minimal retrieval cues, repeatedly, over time.
  • without relying on external memory aids.
  • ...16 more annotations...
  • practice at retrieval has been shown to be more effective than merely spending more time studying the material without actively engaging in memory retrieval.
  • By doing so repeatedly, especially in varied contexts, the learner strengthens access to this information,
  • given minimal cues
  • two different effects. One is the "testing effect," in which intervening tests improves learning of concepts that are retrieved from memory
  • when intervening tests are spaced, two tests were more effective than a single test in improving long-term retention of material.
  • Compared to a cued-recall or recognition intervening test, a free-recall test produced better performance on a final test, regardless of the format of the final test.
  • Educational Applications
  • Align lectures, assignments and tests, so that important information will have to be remembered at different times
  • Have students retrieve this information in multiple ways by either varying the questions or context in which it is assessed:
  • During lectures, ask students questions to elicit responses that reflect understanding of previously introduced course material.
  • This serves the dual purpose of probing students' knowledge, so that misconceptions can be directly and immediately addressed in the lecture.
  • On homework assignments, have students retrieve key information from lectures and readings.
  • Chapter summaries, for instance, may include study questions that ask students to recall major points or conclusions to be drawn from the reading.
  • Encourage group studying in which students actively discuss course topics
  • test questions offer another opportunity for "practice at retrieval,"
  • Ideally tests should be cumulative and test items should probe for understanding of the material.

Teachers Testimonials : TTS Online : Free Text to Speech : Read The Words - 83 views

  • find ReadTheWords.com to be one of the most useful services on the Internet today. Many LD (learning disabled) students struggle with auditory processing.
  • these students are very capable, they tend to favor auditory processing, versus the more common visual processing. It is important that these students learn how their mind works and modify their learning techniques accordingly.
  • 5 students incorporate this service for study of their weekly vocabulary words. We started by making an audio file of the words and definition, and turned it into an mp3 format. The students spent 10 minutes each day on the computer. Each student has averaged a minimum of a full letter grade higher. Two students have received perfect scores for the past 2 weeks.
  • ...12 more annotations...
  • ReadTheWords.com been created to cater to these students.
  • ReadtheWords.com is an AMAZING SERIVCE for young students.
  • ReadTheWords.com allows me to create listening material for some learners that struggle a little bit. It allows my students to read along with the Virtual Avatar Reader. This saves a lot of time so I can focus on certain children without slowing down the rest of the class.
  • We create links to audio files that read our upcoming events, and we use it to help visually impaired patrons read anything - articles, letters they have received, emails that can be copy/pasted from their email account...the possibilities are endless! On a personal level, I have been using ReadTheWords toolbar plug in.
  • service with my university students who are learning English
  • brings the text to life, and stimulates my second language learners in a dynamic way. I would recommend this program to all foreign language teachers,
  • I have been assisting students to create audio files of study review materials. This greatly helps them decode and analyze the material for comprehension. I have seen a great improvement on test scores
  • Students listen to a piece of their own writing, so they can hear if what they wrote sounds correct. It helps students with comprehension, spelling, grammar and structuring sentences.
  • This service is godsend for many students, especially auditory learners. I cannot even begin to imagine how many people this will help in the future. We just received approval to offer this service to our entire school. (Email webmaster@readthewords.com to get a special deal like we did.

      I believe that the audio could act as a reinforcer of the written word as students read. This could be helpful not only with students who are Language Impaired, but also for students who struggle with reading comprehension.
    • Charity Fisher
       
      This website could be benefitical to students who are Hearing Impaired or Learning Disabled in Reading.

      Thsi tool can reinforce the written word and comprehension.

      Something not mentioned by these teachers is the possible benefit to Autistic and Aspergers students. I can this being used as a reward or incentive because the work could be done independently. Since these students generally feel more at ease working independently, it would a motivator to them.
    • Charity Fisher
       
      This could be a great tool for Language Impaired students, but also Learning Disabled in reading as well. The audio would act as a reinforcer of the written material. Even though this is learning or reading comprehension tool, students may see it as a reward thereby motivating them to read more. This could a aid to any teacher attempting to motivate reluctant or struggling readers.

    readthewords.com for Special Ed, ESOL, Low Level Readers, Writing and More!
  •  
    Read The Words could be a beneficial tool to students who are Language Impaired and/or Learning Disabled in Reading. The audio can reinforce the written word and increase comprehension. Also, it could be a valuable tool for autistic students who prefer to work independently. They can use this to aid comprehension and also it could be a reward. This tool could also add interest to text for any student.
