People remember 10%, 20%...Oh Really? - 0 views

  •  
    People do NOT remember 10% of what they read, 20% of what they see, 30% of what they hear, etc. That information, and similar pronouncements are fraudulent. Moreover, general statements on the effectiveness of learning methods are not credible---learning results depend on too many variables to enable such precision. Unfortunately, this bogus information has been floating around our field for decades, crafted by many different authors and presented in many different configurations, including bastardizations of Dale's Cone. The rest of this article offers more detail.

HP Invents a Central Nervous System for the Earth | Inhabitat - 4 views

  • HP has just unveiled an incredibly ambitious project to create a “Central Nervous System for the Earth” (CeNSE) composed of billions of super sensitive, cheap, and tough sensors. The project involves distributing these sensors throughout the world and using them to gather data that could be used to detect everything from infrastructure collapse to environmental pollutants to climate change and impending earthquakes. From there, the “Internet of Things” and smarter cities are right around the corner.HP is currently developing its first sensor to be deployed, which is an accelerometer 1,000 times more sensitive than those used in the Wii or the iPhone – it’s capable of detecting motion and vibrations as subtle as a heartbeat. The company also has plans to use nanomaterials to create chemical and biological sensors that are 100 million times more sensitive than current models. Their overall goal is to use advances in sensitivity and nanotech to shrink the size of these devices so that they are small enough to clip onto a mobile telephone.Once HP has created an array of sensors, the next step is distributing them and making sense of all the data they generate. That’s no easy task, granted that a network of one million sensors running 24 hours a day would create 20 petabytes of data in just six months. HP is taking all that number crunching to task however, and will be harnessing its in-house networking expertise, consulting, and data storage technologies for the project.The creation of a global sensor system would be an incredible breakthrough – it could make our cities more efficient, save lives, and enable us to better understand, track, and combat climate change. As HP Labs senior researcher Peter Hartwell has stated, “If we’re going to save the planet, we’ve got to monitor it“.+ CeNSEVia Fast CompanyLead photo by Margie Wylie Comments RSS Comments RSS digg_url = 'http://www.inhabitat.com/2010/02/18/hp-invents-a-central-nervous-system-for-the-earth/'; digg_title = 'HP Invents a Central Nervous System for the Earth'; digg_skin = 'compact'; email this tweetmeme_url = "http://www.inhabitat.com/2010/02/18/hp-invents-a-central-nervous-system-for-the-earth/"; tweetmeme_style = "compact"; facebook this Related Posts

The Fall, and Rise, of Reading - 1 views

  • During a normal week — whether in two-year or four-year colleges, in the humanities or STEM — about 20 to 40 percent of students do the reading.
  • The average college student in the United States spends six to seven hours a week on assigned reading, according to the National Survey of Student Engagement (which started tracking the statistic in 2013). Other countries report similarly low numbers. But they’re hard to compare with the supposed golden age of the mid-20th century, when students spent some 24 hours a week studying, Baron says. There were far fewer students, they were far less diverse, and their workload was less varied — “studying” meant, essentially, reading books.
  • more students are on track to being ready for college-level reading in eighth and 10th grade” — about 62 percent — “than are actually ready by the time they reach 12th grade.
  • ...10 more annotations...
  • The scores of fourth- and eighth-graders on reading tests have climbed steadily since the 1990s, according to the National Assessment of Educational Progress. But those of 12th-graders have fallen. Just 37 percent of high-school seniors graduate with “proficiency” in reading, meaning they can read a text for both its literal and its inferential meanings.
  • While those with bachelor’s and graduate degrees maintained the highest levels of literacy overall, those groups also experienced the steepest declines. Just 31 percent of college graduates were considered proficient readers in 2003, by that test’s definition, down from 40 percent in 1992.
  • “We quickly realized that unless you actually assign a grade for the out-of-class component, students just won’t do it,”
  • “Harvard students are really not that different in terms of how they behave. They’re bright, they’re academically more gifted,” she says. But they’re also “incredibly good at figuring out how to do exactly what they need to do to get the grade. They’re incredibly strategic. And I think that’s really true of students everywhere.”
  • turns the classroom into a social-learning environment
  • “We have young people who are coming away from high school with a very sort of test-driven training — I won’t call it education — training in reading.”
  • Teaching students how to read in college feels “remedial” to many professors
  • Faculty members are trained in their disciplines. “They don’t want to be reading teachers. I don’t think it’s a lack of motivation,” says Columbia’s Doris Perin. “They don’t feel they have the training.” Nor do they want to “infantilize” students by teaching basic comprehension skills, she says.
  • Tie reading to a grade: Quizzes and assigned journals, which can determine about 20 percent of the final grade, can double or even triple reading compliance — but rote formats that seem to exist for their own sake can encourage skimming or feel punitive.“Do away with the obvious justifications for not doing the reading,” says Naomi Baron, at American U. “If you summarize everything that’s in the reading, why should students do it?”Ask students to make arguments, compare, and contrast — higher- order skills than factual recall.Using different media is fine, but maintain rigor. “You can do critical reading of anything that has essentially an academic argument in it,” says David Jolliffe, at the U. of Arkansas. Video and audio, in fact, may sometimes be better than textbooks — what he calls “predigested food.”Explicitly tie out-of-class reading to in-class instruction, going over points of confusion and connecting lessons and texts to each other.Teach reading skills. “Hundreds” of strategies exist, all of which make “explicit the processes that proficient readers use without thinking about it,” says Doris Perin, at Columbia.
  • “A lot of faculty members, myself included, are saying, If they’re not doing the reading, we can get unhappy, we can get angry,” she says. “Or we can do something about it.”

Facebook Wants to Welcome Kids Under Age 13 to Social Network - Search Engine Watch (#SEW) - 12 views

  •  
    One of my students turned up this information that Facebook is working on controls to help kids under 13 use the service. It is no surprise that 7.5 million Facebook users are under the age of 13 and that 5 million of THOSE are 10 years old or younger. COPPA, while set up to protect children, is actually keeping them from participating in society as they want to. This infographic and information is worth sharing as you educate your students. If you want until they are 13 to talk safety online, that is too late. "Last June, Consumer Reports magazine said they had unearthed "several disturbing findings" about children and Facebook, including: 20 million minors had used Facebook within the year prior to their study. 7.5 million of those users were under the age of 13 and not permitted to use the site. 5 million of those were 10 years old or younger. 1 million children had been harassed, threatened, or subjected to other forms of cyberbullying in the year prior."

High School Publishers' Criteria for the Common Core State Standards for Mathematics - 0 views

  •  
    Last week a 20 page document was issued from the Common Core Math standards writers to make "more clearly visible" where materials faithfully reflect both the letter and spirit of the math standards... I read in this... just because it SAYS it is common core math aligned, doesn't mean it is. Read this before buying and tread with caution.

Finger-free phones, full body gesturing, and our "touchscreen" future | Ars Technica - 8 views

  •  
    I think those who think that we will not need keyboards are missing a few important points. Here's the issue - I can type faster than I can talk. Also, in the classroom - 20 kids talking to their computers it would be chaos and a mess. Typing, however, has a speed benefit and doesn't require a "cone of silence" as a everyone talking to their glasses would. I think keyboarding will remain part of the productive equipment of most of us - until our devices can read our brain waves. For those who type less than 30 words a minute and work in a quiet office, this is likely to be true. Meanwhile, this is a great read about what will happen in our homes, at least.

Twitter Itself Will Soon Decide the Value of Your Tweets - 0 views

  •  
    Twitter is going to "rate" your tweets in the hopes of giving you and developers better content. Again, those late to the game may have trouble being heard, but I'd like to think there is always a way to be valuable. Never assume that because everyone is following someone that they have something worth saying - decide who YOU want to follow and that is enough. Of course, when this happens, expect the usual uproar of those who are valued and not valued, as for me, I hope I can resist the urge to start comparing in sharing and just try to stay helpful. From Mashable..."The value judgements will be assigned to the public metadata of tweeters' posts, and used by Twitter's streaming API to help developers more selectively curate massive amounts of status updates. Designations of "none," "low" and "medium" will most likely debut on Feb. 20, according to a post by developer advocate Arne Roomann-Kurrik on the Twitter developers' blog. A "high" value option will be rolled out sometime after the initial batch."

Wichita teachers union balks at lesson-plan requirements | The Daily Caller - 0 views

  •  
    There are many who don't understand this one point. I used to have someone who required me to have beautiful lesson plans. They were detailed. I spent more than an hour a day on them. So much time so that sometimes I felt unprepared when the kids actually walked in the door. When those detailed plans were removed and I was allowed to focus on the content created for the students to use and then keep a grid (I keep links, etc. to what I'm doing) - THAT Was when real innovation happened in my classroom. Things like wikis, blogs, etc. happened after those super-restrictive requirements were taken off my shoulders. I had the wrong audience when I had those detailed lesson plans - my audience was the principal at the time. Now, I still have plans but I keep it in a grid in a book and then keep copies of what I use with students in dropbox and other places. I do far more now than then because my focus is the students. Lesson plans aren't bad. However, if you spend your time making the LESSON PLAN itself pretty and perfect then likely you're not spending your actual time PLANNING, printing, collecting, and creating what you'll be doing with your students. Also, when you do things like #geniushour and 20% time projects, you no longer have a lesson plan but a project plan which is an entirely different thing altogether. Don't fault teachers for this.  Teaching is the hardest job everybody thinks they can do and few really can.

20 Tips for a New Trainee Teacher! by @trainingtoteach - 3 views

    Now that I am venturing into my second year as a trainee teacher (yay me!), I've learnt a lot, I've made a lot of mistakes, made friends, made enemies, delivered some brilliant lessons and some so bad, I've wondered if maybe, just maybe I'd be better off sitting in the class, rather than teaching it.
