15 Excel Formulas, Keyboard Shortcuts & Tricks That'll Save You Lots of Time - 35 views

  •  
    For most marketers, trying to organize and analyze spreadsheets in Microsoft Excel can feel like walking into a brick wall over and over again. You're manually replicating columns and scribbling down long-form math on a scrap of paper, all while thinking to yourself, "There has to be a better way to do this." Truth be told, there is -- you just don't know it yet. Excel can be tricky that way. On the one hand, it's an exceptionally powerful tool for reporting and analyzing marketing data. On the other, without the proper training, it's easy to feel like it's working against you. For starters, there are more than a dozen critical formulas Excel can automatically run for you so you're not combing through hundreds of cells with a calculator on your desk.

ISSIE LAPOWSKY DATE OF PUBLICATION: 05.04.15. 05.04.15 TIME OF PUBLICATION: 7:00 AM. 7:00 AM INSIDE THE SCHOOL SILICON VALLEY THINKS WILL SAVE EDUCATION Click to Open Overlay Gallery Students in the youngest class at the Fort Mason AltSchool help their teacher, Jennifer Aguilar, compile a list of what they know and what they want to know about butterflies. CHRISTIE HEMM KLOK/WIRED SO YOU'RE A parent, thinking about sending your 7-year-old to this rogue startup of a school you heard about from your friend's neighbor's sister. It's prospective parent information day, and you make the trek to San Francisco's South of Market neighborhood. You walk up to the second floor of the school, file into a glass-walled conference room overlooking a classroom, and take a seat alongside dozens of other parents who, like you, feel that public schools-with their endless bubble-filled tests, 38-kid classrooms, and antiquated approach to learning-just aren't cutting it. At the same time, you're thinking: this school is kind of weird. On one side of the glass is a cheery little scene, with two teachers leading two different middle school lessons on opposite ends of the room. But on the other side is something altogether unusual: an airy and open office with vaulted ceilings, sunlight streaming onto low-slung couches, and rows of hoodie-wearing employees typing away on their computers while munching on free snacks from the kitchen. And while you can't quite be sure, you think that might be a robot on wheels roaming about. Then there's the guy who's standing at the front of the conference room, the school's founder. Dressed in the San Francisco standard issue t-shirt and jeans, he's unlike any school administrator you've ever met. But the more he talks about how this school uses technology to enhance and individualize education, the more you start to like what he has to say. And so, if you are truly fed up with the school stat

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?

  • If the new trend in textbooks is moving them to computer screens, the switch could have negative consequences as many suggest that people skim more, process more shallowly, and may retain less information when reading online, Daniel said.
  • he readers’ goals are different: Individuals reading an e-book for enjoyment aren’t required to pass a comprehension-based test afterward. While they found that learning is possible from both formats, learning from e-textbooks takes longer and requires more effort to reach the same level of understanding, even in a controlled lab environment. At home, students report taking even more time to read e-textbooks as well as higher rates of muti-tasking (e.g., Facebook, electronic chat, texting, email, etc.) than do their peers using printed textbooks.
  • In their preliminary findings, the scanning pattern produced when the student read a textbook showed consistent reading from line to line down the page. But the scanning pattern from reading on the screen was less intense.

  • Daniel and Jakobsen argue that the information dense textbooks characteristic of natural and social science subjects are not a good fit for current e-textbooks, but there are exceptions for subjects like chemistry and math that include doing formulas and other activities. The liability, Daniel emphasizes, comes when math and chemistry teachers hope their students will learn the explanations, not just the formulas, “Students tend to skip the text and go straight to the formulas, especially if they are graded.”

Trust me, there is no formula for most things that are not math.

The Answer Factory: Demand Media and the Fast, Disposable, and Profitable as Hell Media... - 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.
  • ...3 more annotations...
  • 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.

Yes, Your Syllabus Is Way Too Long - The Chronicle of Higher Education - 23 views

  •  
    If you're a faculty member, you've spent the last few weeks preparing your syllabus for the spring semester. You've updated the document and added a little to it. This latest round of edits may have pushed your syllabus another page longer - most now run about five pages, though nearly every campus has lore of some that exceed 20. Lamentations about syllabus bloat started emerging about seven years ago in moods ranging from nostalgia to bemusement to curiosity to irritation to full-blown ideological critique. Based on 20 years of serving on curriculum committees and working with academics across the disciplines on teaching, I agree that, yes, the typical syllabus has now become a too-long list of policies, learning outcomes, grading formulas, defensive maneuvers, recommendations, cautions, and referrals. As a writing-center director who has encouraged instructors to add a pitch for tutoring services, I'm complicit.

Book: How to be an Outstanding Primary School Teacher by @HeadTeachDunn - 9 views

  •  
    "With so many expectations, requirements and scrutiny of primary school teachers, it is easy to become formulaic in your practice. This is a shame, as the initial enthusiasm for the job gets waned, and giving young students the opportunity to shine becomes less focused on whole-child development. However, to become an outstanding teacher demands consistency, focus and dedication. Outstanding teachers are always on the lookout for new ideas, but sometimes the tried-and-tested classroom activities and techniques can offer a strong system to help your pupils shine, despite curriculum restraints imposed."

What measures the best teacher? More than scores, study shows - 1450 WHTC Holland's Hom... - 138 views

  • researchers found they could pick out the best teachers in a school and even predict roughly how much their students would learn if they rated the educators through a formula that put equal weight on student input, test scores and detailed classroom observations by principals and peers
  • Judging teachers primarily by student performance on state tests, for instance, turned out to be highly unreliable, with little consistency from year to year. Judging them chiefly by a principal's observations failed to identify those teachers who could be counted on to boost student proficiency on state math and reading tests.
  • This should be a very big red flag to all those policy makers who think they can have test-based accountability be half or more of a teacher's evaluation
  •  
    "(Reuters) - Effective teachers can be identified by observing them at work, measuring their students' progress on standardized tests - and asking those students directly what goes on in the classroom, according to a comprehensive study released Tuesday."

The Coach in the Operating Room - The New Yorker - 37 views

  • I compared my results against national data, and I began beating the averages.
    • anonymous
       
      this is one of the most important reasons for data and using the data to help guide instruction
  • the obvious struck me as interesting: even Rafael Nadal has a coach. Nearly every élite tennis player in the world does. Professional athletes use coaches to make sure they are as good as they can be.
    • anonymous
       
      Why wouldn't we want a coach? Our supervisor or administrator often serves as an evaluator but might not have the time due to time constraints to serve as an effective and dedicated coach. Yet, a coach doesn't have to be an expert. Couldn't the coach just be a colleague with a different skill set?

      Please tell me what profession isn't always evolving? It something isn't evolving, it is dying! So, why doesn't everyone on the face of the earth - regardless of his/her profession or station in life - need coaching periodically to help them continue to grow and evolve?
  • We have to keep developing our capabilities and avoid falling behind.
  • no matter how well prepared people are in their formative years, few can achieve and maintain their best performance on their own.
  • outside ears, and eyes, are important
  • For decades, research has confirmed that the big factor in determining how much students learn is not class size or the extent of standardized testing but the quality of their teachers.
    • anonymous
       
      So, instead of having students take test after test after test, why don't we just have coaches who observe and sit and discuss and offer suggestions and divide the number of tests we give students in half and do away with half? Are we concerned about student knowledge? student performance? student ability? student growth or capacity for growth? What we really need to identify is what we value!
  • California researchers in the early nineteen-eighties conducted a five-year study of teacher-skill development in eighty schools, and noticed something interesting. Workshops led teachers to use new skills in the classroom only ten per cent of the time. Even when a practice session with demonstrations and personal feedback was added, fewer than twenty per cent made the change. But when coaching was introduced—when a colleague watched them try the new skills in their own classroom and provided suggestions—adoption rates passed ninety per cent. A spate of small randomized trials confirmed the effect. Coached teachers were more effective, and their students did better on tests.
    • anonymous
       
      Of course they are more effective! They have a trusted individual to guide them, mentor them, help sustain them. The coach can cheer and affirm what the teacher is already doing well and offer suggestions that are desired and sought in order to improve their 'game' and become more effective.
  • they did not necessarily have any special expertise in a content area, like math or science.
    • anonymous
       
      Knowledge of the content is one thing and expertise is yet another. Sometimes what makes us better teachers is simply strategies and techniques - not expertise in the content. Sometimes what makes us better teachers could simply be using a different tool or offering options for students to choose.
  • The coaches let the teachers choose the direction for coaching. They usually know better than anyone what their difficulties are.
    • anonymous
       
      The conversation with the coach and the coach listening and learning what the teacher would like to expand, improve, and grow is probably the most vital part! If the teacher doesn't have a clue, the coach could start anywhere and that might not be what the teacher adopts and owns. So, the teacher must have ownership and direction.
  • teaches coaches to observe a few specifics: whether the teacher has an effective plan for instruction; how many students are engaged in the material; whether they interact respectfully; whether they engage in high-level conversations; whether they understand how they are progressing, or failing to progress.

      This could provide specific categories to offer teachers a choice in what direction they want to go toward improving - especially important for those who want broad improvement or are clueless at where to start.
  • must engage in “deliberate practice”—sustained, mindful efforts to develop the full range of abilities that success requires. You have to work at what you’re not good at.

5 Reasons Why Origami Improves Students' Skills | Edutopia - 59 views

  • origami
  • This art form engages students and sneakily enhances their skills -- including improved spatial perception and logical and sequential thinking.
  • Here are some ways that origami can be used in your classroom to improve a range of skills:
  • ...14 more annotations...
  • Geometry
  • According to the National Center for Education Statistics in 2003, geometry was one area of weakness among American students.
  • Origami has been found to strengthen an understanding of geometric concepts, formulas, and labels, making them come alive.
  • Thinking Skills
  • Origami excites other modalities of learning. It has been shown to improve spatial visualization skills using hands-on learning.
  • Fractions
  • Folding paper can demonstrate the fractions in a tactile way.
  • Problem Solving
  • Often in assignments, there is one set answer and one way to get there. Origami provides children an opportunity to solve something that isn't prescribed and gives them a chance to make friends with failure (i.e. trial and error).
  • Origami is a fun way to explain physics concepts. A thin piece of paper is not very strong, but if you fold it like an accordion it will be.
  • Researchers have found that students who use origami in math perform better.
  • STEAM
  • While schools are still catching up to the idea of origami as a STEAM engine (the merging of these disciplines), origami is already being used to solve tough problems in technology.
  • Additionally, the National Science Foundation, one of the government's largest funding agencies, has supported a few programs that link engineers with artists to use origami in designs. The ideas range from medical forceps to foldable plastic solar panels.
  •  
    Origami, the ancient art of paper folding, has applications in the modern-day classroom for teaching geometry, thinking skills, fractions, problem solving, and fun science.
