Where are the savings in using GoogleApps? - Home - Doug Johnson's Blue Skunk... - 12 views

  • These are rough and admittedly optimistic estimates, but I think you can see the general trend. Even if only 50% of my estimated nearly $2M in savings is realized, that averages out to close to $200,000 per year. (Out of a $1.2M budget.) I am not suggesting reducing tech budgets by this amount, but I can sure think of a lot more interesting things (like kids' computers, a more robust wireless network, and more bandwidth) to spend tech dollars on. Yes, I need to pay $7 a year per administrative, possibily teacher, e-mail account for archiving and retrieval. Not bad, though, considering.

    Doug Johnson estimates the savings moving to Google apps, Great post for those considering this.

Fire first, ask questions later? Comments on Recent Teacher Effectiveness Stu... - 4 views

  • For teachers with a relatively short track record in a given school, grade level and specific assignment, and schools with many such teachers, this statistical twist has little practical application, especially in the context of annual teacher evaluation and personnel decisions.
  •  
    "These are interesting findings. It's a really cool academic study. It's a freakin' amazing data set! But these findings cannot be immediately translated into what the headlines have suggested - that immediate use of value-added metrics to reshape the teacher workforce can lift the economy, and increase wages across the board! The headlines and media spin have been dreadfully overstated and deceptive. Other headlines and editorial commentary has been simply ignorant and irresponsible. (No Mr. Moran, this one study did not, does not, cannot negate the vast array of concerns that have been raised about using value-added estimates as blunt, heavily weighted instruments in personnel policy in school systems.)"

In Pakistan, a New Push for Education by Mujib Mashal on Beacon - 0 views

  •  
    Pakistan is pushing to educate more of its children, amidst financial woes and a struggle for more funding. Their goal: 100% enrollment. Of course, there is a great effort also to build a firewall in Pakistan much like the "great firewall of China." That said, there are many lovely educators from Pakistan who contribute and connect increasingly online and I wish this country well as well as the many countries working to increase enrollment. "As schools returned to session in Pakistan's northwestern Khyber Pakhtunkhwa (KP) province this fall, the newly elected provincial government - with the help of the non-profit campaign Alif Ailaan - launched an enrollment drive. In its first month, the drive managed to enroll nearly 245,000 out of school children - about 65% male and 35% female - across 25 districts of the province, according to figures provided by Alif Ailaan. But considering Pakistan's education woes, where more than 25 million children between the ages of 5-16 remain out of school, it is a small step. "In order to provide schooling to all the kids, we need about Rs. 138 billion (roughly $1.2 billion) just in KP - for school infrastructure, classrooms, teachers so on and so forth," Joudat Ayaz, the province's education secretary, told me over dinner. Ayaz estimates the number of out of school children in KP between 2 to 3 million, about 20% to 30% of the school-age children in the province. "You can't do this [reaching 100% enrollment] in one go - you have to do it progressively, over six or seven years.""

FiveThirtyEight.com: Electoral Projections Done Right - 0 views

  •  
    There are several ways that the FiveThityEight methodology differs from other poll compilations. Firstly, we assign each poll a weighting based on that pollster's historical track record, the poll's sample size, and the recentness of the poll. More reliable polls are weighted more heavily in our averages. Secondly, we include a regression estimate based on the demograhics in each state among our 'polls', which helps to account for outlier polls and to stabilize the results. Thirdly, we simulate the election 10,000 times for each site update in order to provide a probabilistic assessment of electoral outcomes.

High Scalability - High Scalability - The Amazing Collective Compute Power of... - 4 views

  • Earlier we talked about how a single botnet could harness more compute power than our largest super computers. Well, that's just the start of it. The amount of computer power available to the Ambient Cloud will be truly astounding.
  • By 2014 one estimate is there will be 2 billion PCs. That's a giant reservoir of power to exploit, especially considering these new boxes are stuffed with multiple powerful processors and gigabytes of memory. 7 Billion Smartphones By now it's common wisdom smartphones are the computing platform of the future. It's plausible to assume the total number of mobile phones in use will roughly equal the number of people on earth. That's 7 billion smartphones. Smartphones aren't just tiny little wannabe computers anymore either. They are real computers and are getting more capable all the time.
  • One Google exec estimates that in 12 years an iPod will be able to store all the video ever produced.

  • But all the compute power in the world is of little use if the cores can't talk to each other.
  • Inductive chargers will also make it easier to continually charge devices. Nokia is working on wireless charging. And devices will start harvesting energy from the surroundings. So it looks like the revolution will be fully powered.
  • . Literally billions of dollars are being invested into developing a giant sensor grids to manage power. Other grids will be set up for water, climate, pollution, terrorist attacks, traffic, and virtually everything else you can think to measure and control.
  • . Others predict the smart grid could be 1,000 times larger than the Internet.
  • Clearly this technology has obvious health and medical uses, and it may also figure into consumer and personal entertainment.
  • What if instead smartphones become the cloud?
  • In the future compute capacity will be everywhere. This is one of the amazing gifts of computer technology and also why virtualization has become such a hot datacenter trend.
  • It's out of that collective capacity that an Ambient Cloud can be formed, like a galaxy is formed from interstellar dust. We need to find a more systematic way of putting it to good use.

Views: Why Grading Is Part of My Job - Inside Higher Ed - 3 views

  • Grades serve no pedagogical function at all. (Detailed feedback does, but that's an entirely different matter.) Grading is about nothing more than efficiently communicating to other institutions the level of learning we, the teachers, estimate (and it is only an estimation) each student gained. Unfortunately, students not only want to know about the content of that communication (understandably enough) but, for many, maximizing the grade (rather than the learning itself) has become their primary goal in taking courses. If we had no grades, then students' own personal sense of learning would be all that they got out of taking courses, and they would focus on that instead. (And it would make courses a much more interesting and productive place to be.)

Teachers: Is AI Coming to Take Your Job? by @AIConf2018 - 1 views

  •  
    "Artificial Intelligence is a hot topic at the moment, with estimates varying wildly about how many jobs will be replaced by machine learning algorithms. Whatever the outcome, in reality, it is clear that schools will need to change, in order to prepare their students for the resulting impact on society and the skills needed for future employment."

The crisis of student mental health is much vaster than we realize - The Washington Post - 1 views

  • the CDC found nearly 45 percent of high school students were so persistently sad or hopeless in 2021 they were unable to engage in regular activities. Almost 1 in 5 seriously considered suicide, and 9 percent of the teenagers surveyed by the CDC tried to take their lives during the previous 12 months. A substantially larger percentage of gay, lesbian, bisexual, other and questioning students reported a suicide attempt
  • More than 230,000 U.S. students under 18 are believed to be mourning the ultimate loss: the death of a parent or primary caregiver in a pandemic-related loss, according to research by the CDC, Imperial College London, Harvard University, Oxford University and the University of Cape Town. In the United States, children of color were hit the hardest, another study found. It estimated that the loss for Black and Hispanic children was nearly twice the rate of White children.
  • Professional organizations recommend one school psychologist per 500 students, but the national average is one per 1,160 students, with some states approaching one per 5,000. Similarly, the recommended ratio of one school counselor per 250 students is not widespread. The national average: one per 415 students.

  • Seattle teachers who went on strike in September included a call for more mental health supports for students as one of their bargaining points. The strike settlement included part-time social workers at most schools
  • “We’ve seen increases in anxiety, disordered eating, suicidal ideation, OCD and many other mental health challenges,”
  • Last school year, nearly 40 percent of schools nationally reported increases in physical attacks or fights, and roughly 60 percent reported more disruptions in class because of student misconduct, according to federal data.
  • “School-based health centers fill a void, particularly in low-income communities,” said Robert Boyd, chief executive at the nonprofit School-Based Health Alliance. “In rural communities, sometimes it’s the only provider around.”
  • school systems are expanding social-emotional learning intended to help students understand and regulate their emotions, develop positive relationships and face challenges. These lessons may be embedded in classes (say, a discussion of empathy related to characters in a novel) or they may come directly through an activity about, for instance, decision-making. In some parts of the country, social-emotional teachings are tangled up in the culture wars, particularly when material deals with gender and racial equity.
  • Critics see the excused days off as counterproductive for students who have already missed too much school, but supporters say the laws recognize the stressful reality of many students’ lives and elevate the stature of mental health so that it is comparable to physical health.
