Building A Better Mousetrap: The Rubric Debate - 126 views

  • If the rubric is primarily used for instruction and will be shared with your students, then it should be non-judgemental, free of educational jargon, and reflect the critical vocabulary that you use in your classroom.
    • Amy Burns
       
      Important point! The vocabulary of the rubric must be easily understood by all of the student in the class.
  • While many educators make a compelling argument for sharing rubrics with students, others worry that doing so will encourage formulaic writing
    • Amy Burns
       
      This is why I sometimes struggle with rubrics. A project might be technically correct, but lack originality and creativity. Creativity is hard to scale.

How to Fix Our Math Education - NYTimes.com - 63 views

  • the assumption that there is a single established body of mathematical skills that everyone needs to know to be prepared for 21st-century careers. This assumption is wrong. The truth is that different sets of math skills are useful for different careers, and our math education should be changed to reflect this fact.
  • Today, American high schools offer a sequence of algebra, geometry, more algebra, pre-calculus and calculus (or a “reform” version in which these topics are interwoven). This has been codified by the Common Core State Standards, recently adopted by more than 40 states. This highly abstract curriculum is simply not the best way to prepare a vast majority of high school students for life.
  • A math curriculum that focused on real-life problems would still expose students to the abstract tools of mathematics, especially the manipulation of unknown quantities. But there is a world of difference between teaching “pure” math, with no context, and teaching relevant problems that will lead students to appreciate how a mathematical formula models and clarifies real-world situations.

  • For instance, how often do most adults encounter a situation in which they need to solve a quadratic equation? Do they need to know what constitutes a “group of transformations” or a “complex number”? Of course professional mathematicians, physicists and engineers need to know all this, but most citizens would be better served by studying how mortgages are priced, how computers are programmed and how the statistical results of a medical trial are to be understood.
  • Imagine replacing the sequence of algebra, geometry and calculus with a sequence of finance, data and basic engineering.
  • Traditionalists will object that the standard curriculum teaches valuable abstract reasoning, even if the specific skills acquired are not immediately useful in later life. A generation ago, traditionalists were also arguing that studying Latin, though it had no practical application, helped students develop unique linguistic skills. We believe that studying applied math, like learning living languages, provides both useable knowledge and abstract skills.
  • In math, what we need is “quantitative literacy,” the ability to make quantitative connections whenever life requires (as when we are confronted with conflicting medical test results but need to decide whether to undergo a further procedure) and “mathematical modeling,” the ability to move practically between everyday problems and mathematical formulations (as when we decide whether it is better to buy or lease a new car).

Coh-Metrix - 30 views

  • five major factors that account for most of the variance in texts across grade levels and text categories: word concreteness, syntactic simplicity, referential cohesion, causal cohesion, and narrativity
  •  
    Computer analyses of text characteristics are often used by reading teachers, researchers, and policy makers when selecting texts for students. The authors of this article identify components of language, discourse, and cognition that underlie traditional automated metrics of text difficulty and their new Coh-Metrix system. Coh-Metrix analyzes texts on multiple measures of language and discourse that are aligned with multilevel theoretical frameworks of comprehension. The authors discuss five major factors that account for most of the variance in texts across grade levels and text categories: word concreteness, syntactic simplicity, referential cohesion, causal cohesion, and narrativity. They consider the importance of both quantitative and qualitative characteristics of texts for assigning the right text to the right student at the right time.

    How do we go about selecting texts for individualized reading assistance? This sounds like a new way.

If you want to innovate like Da Vinci, education is overrated | TechRepublic - 46 views

  • Thiel is a venture capitalist and the game that VCs play is to invest in 10 different ideas with the hope that one of them hits it big, while the other nine are likely to fail, morph into something different, or simply fade away.
  • Bill Gates (Microsoft) and Mark Zuckerberg (Facebook). Yes, both dropped out of Harvard to start a company and eventually became billionaires, but before they went to college both of them got an outstanding education that was certainly a springboard to their later achievements.
  • A college education trains and teaches students how to best plug themselves into the current civilization. Education helps you plug into the things society already needs, to plug into society as it is today. It’s not about tomorrow

  • Da Vinci basically out-observed everyone in his generation? That was critical. He spent a lot of time observing and figuring out where there were important problems and pain points that could be improved by either iterating or innovating. It’s a simple but powerful formula. Lots of organizations could do a better job of carefully observing the best opportunities to target, and then attacking the opportunity with their best ideas.
  • Innovation is about what’s next. To pull off a big innovation, you almost always have to take a big risk. You have to try something different.

    In reference to Gates and others who have shined, according to Gladwell's "Outliers" they have also most likely put in the time (10,000 plus hours) practicing, envisioning, and imagining what they want to create. Innovation takes time input, imagination, desire, and risk...

5 myths about teachers that are distracting policymakers - The Answer Sheet - The Washington Post - 111 views

  • Political leaders at every level are demanding we evaluate and pay teachers based on student test scores and value-added statistical formulas. If that turns out to be a bad strategy, the long-term ramifications for the nation could be staggering.
  •  
    "Now's the time to transcend the usual debates over how to make our schools better and our teachers more effective - and break free of the myths that keep us fighting 20th century battles. Instead we need to look hard at the realities, framed by research evidence as well as the challenges teachers face everyday"

To Share or Not to Share: Is That the Question? (EDUCAUSE Review) | EDUCAUSE - 28 views

  • Open digital faculty do more than just share and participate in open resources; they transfer their approaches to the teaching space. Learning becomes a shared activity in which the students also collaborate and participate in shaping the course activities. Student participation takes place in open environments where students might tweet what they learn, share insights on a group blog, create their own website of resources, or participate in a class wiki.
  • The difference is that today's sharing facilitators leverage technology to reach a much wider audience.
  • Although the natural inclination toward sharing cannot be altered, the moral responsibility to share can be influenced by the surrounding culture. The sense of obligation to share or not to share may be similar to the decision to be a vegetarian. For some, it is a lifestyle choice that may form slowly over a long period of time after many conversations with friends and colleagues. For others, the change can be sudden: a paradigm shift caused by participation in an unusual event. If an institution places value on faculty participation in open academic communities and social media activities (e.g., academic blogging), that culture can slowly influence faculty to be more open.

  • These digital activities should not be the sole measure of tenure, but they should be counted in the tenure formula. The irony today is that if the open activity is analog (e.g., participation on a committee), it likely counts toward tenure, but if the open activity is digital (e.g., writing an academic blog), it probably does not.
  • They will push at (and leak out of) the boundaries of whatever learning management system (or other enterprise systems) the institution wants them to use. This is not because they are uncooperative; it's simply that these enterprise systems tend to be locked down, allowing only employees and students to share within these environments
  • For me, an interesting side effect of sharing on the open web is that I've learned to be more careful about what I say and write.
  • Looking for indicators of open digital faculty is easier than coming up with a strict definition. The presence of several of the following characteristics should be taken as an indication of open digital faculty: Writing a public blog or maintaining a public wiki to share academic interests Freely sharing what might otherwise be guarded intellectual property (e.g., textbooks, research-in-progress, computer programs, course materials, artwork) Participating in a learning community in a social networking platform (e.g., Twitter or LinkedIn discussion groups) Participating in a social network that includes students, both current and past (e.g., Facebook) Encouraging students to participate in class-related projects that employ web-based media (e.g., student blogs, group wikis) Creating or participating in open courses Sharing video or audio content created for a course (e.g., podcasts) Sharing information and ideas from conference talks on the web (e.g., recordings, tweets, presentation links)

Math - Online Calculator - Formula Library - 87 views

  •  
    My students in physics classes always come in with a broad range of math ability. Through the class, I teach and reteach a lot of math and sometimes understanding the content gets lost in the stresses of learning the math/algebra. Though to truely understand the interplay between rates and proportions involved a strong math background helps the content and big picture can be grasped even if the math must be buoyed. I hope this program assists my students this year to be more confident with the math so the physics concepts do not get lost.

Enhancing Critical-Thinking Skills in Children: Tips for Parents - Duke Gifted Letter - 55 views

  • Are in-depth group discussions provided during class time? Are students coached to question their thinking processes and those of their classmates? Are students afforded opportunities to evaluate their progress regularly? Are students encouraged to pose questions regularly in class? Are students provided with guides to help them reflect on their thinking (such as Bloom’s Taxonomy)? Do class projects engage students in analysis, synthesis, and evaluation? Are students given opportunities to consider various opinions and to justify their own beliefs?
  • Table 1 Bloom's Cognitive Taxonomy Competence Description Question/Prompt Knowledge Dates, events, formulas, other facts When did the United States become an independent country from England? What is the formula for area? Comprehension Recognize meaning, sequence, events, interpret information, compare ideas, make inferences, predict ideas What is the author's purpose?

The Answer Factory: Demand Media and the Fast, Disposable, and Profitable as Hell Media Model | Magazine - 24 views

  • Pieces are not dreamed up by trained editors nor commissioned based on submitted questions. Instead they are assigned by an algorithm, which mines nearly a terabyte of search data, Internet traffic patterns, and keyword rates to determine what users want to know and how much advertisers will pay to appear next to the answers.
  • To appreciate the impact Demand is poised to have on the Web, imagine a classroom where one kid raises his hand after every question and screams out the answer. He may not be smart or even right, but he makes it difficult to hear anybody else.
  • But what Demand has realized is that the Internet gets only half of the simplest economic formula right: It has the supply part down but ignores demand. Give a million monkeys a million WordPress accounts and you still might never get a seven-point tutorial on how to keep wasps away from a swimming pool. Yet that’s what people want to know.

  • That’s not to say there isn’t any room for humans in Demand’s process. They just aren’t worth very much. First, a crowdsourced team of freelance “title proofers” turn the algorithm’s often awkward or nonsensical phrases into something people will understand: “How to make a church-pew breakfast nook,” for example, becomes “How to make a breakfast nook out of a church pew.” Approved headlines get fed into a password-protected section of Demand’s Web site called Demand Studios, where any Demand freelancer can see what jobs are available. It’s the online equivalent of day laborers waiting in front of Home Depot. Writers can typically select 10 articles at a time; videographers can hoard 40. Nearly every freelancer scrambles to load their assignment queue with titles they can produce quickly and with the least amount of effort — because pay for individual stories is so lousy, only a high-speed, high-volume approach will work. The average writer earns $15 per article for pieces that top out at a few hundred words, and the average filmmaker about $20 per clip, paid weekly via PayPal. Demand also offers revenue sharing on some articles, though it can take months to reach even $15 in such payments. Other freelancers sign up for the chance to copyedit ($2.50 an article), fact-check ($1 an article), approve the quality of a film (25 to 50 cents a video), transcribe ($1 to $2 per video), or offer up their expertise to be quoted or filmed (free). Title proofers get 8 cents a headline. Coming soon: photographers and photo editors. So far, the company has paid out more than $17 million to Demand Studios workers; if the enterprise reaches Rosenblatt’s goal of producing 1 million pieces of content a month, the payouts could easily hit $200 million a year, less than a third of what The New York Times shells out in wages and benefits to produce its roughly 5,000 articles a month.
  • But once it was automated, every algorithm-generated piece of content produced 4.9 times the revenue of the human-created ideas. So Rosenblatt got rid of the editors. Suddenly, profit on each piece was 20 to 25 times what it had been. It turned out that gut instinct and experience were less effective at predicting what readers and viewers wanted — and worse for the company — than a formula.
  • Here is the thing that Rosenblatt has since discovered: Online content is not worth very much. This may be a truism, but Rosenblatt has the hard, mathematical proof. It’s right there in black and white, in the Demand Media database — the lifetime value of every story, algorithmically derived, and very, very small. Most media companies are trying hard to increase those numbers, to boost the value of their online content until it matches the amount of money it costs to produce. But Rosenblatt thinks they have it exactly backward. Instead of trying to raise the market value of online content to match the cost of producing it — perhaps an impossible proposition — the secret is to cut costs until they match the market value.
