  • Photo Tampering Throughout History Photography lost its innocence many years ago. In as early as the 1860s, photographs were already being manipulated, only a few decades after Niepce created the first photograph in 1814. With the advent of high-resolution digital cameras, powerful personal computers and sophisticated photo-editing software, the manipulation of digital images is becoming more common. Here, I have collected some examples of tampering throughout history. To help contend with the implications of this tampering, we have developed a series of tools for detecting traces of tampering in digital images (contact me at Ma'at Consulting for more information about our services). circa 1860: This nearly iconic portrait of U.S. President Abraham Lincoln is a composite of Lincoln's head and the Southern politician John Calhoun's body. Putting the date of this image into context, note that the first permanent photographic image was created in 1826 and the Eastman Dry Plate Company (later to become Eastman Kodak) was created in 1881. circa 1865: In this photo by famed photographer Mathew Brady, General Sherman is seen posing with his Generals. General Francis P. Blair (far right) was added to the original photograph.

  • In his deliberately provocative — and deeply nihilistic — new book, “Reality Hunger,” the onetime novelist David Shields asserts that fiction “has never seemed less central to the culture’s sense of itself.”
  • Mr. Shields’s book consists of 618 fragments, including hundreds of quotations taken from other writers like Philip Roth, Joan Didion and Saul Bellow — quotations that Mr. Shields, 53, has taken out of context and in some cases, he says, “also revised, at least a little — for the sake of compression, consistency or whim.”
  • It’s also a question, as Mr. Lanier, 49, astutely points out in his new book, “You Are Not a Gadget,” of how online collectivism, social networking and popular software designs are changing the way people think and process information, a question of what becomes of originality and imagination in a world that prizes “metaness” and regards the mash-up as “more important than the sources who were mashed.”
  • ...2 more annotations...
  • Mr. Lanier’s book, which makes an impassioned case for “a digital humanism,” is only one of many recent volumes to take a hard but judicious look at some of the consequences of new technology and Web 2.0. Among them are several prescient books by Cass Sunstein, 55, which explore the effects of the Internet on public discourse; Farhad Manjoo’s “True Enough,” which examines how new technologies are promoting the cultural ascendancy of belief over fact; “The Cult of the Amateur,” by Andrew Keen, which argues that Web 2.0 is creating a “digital forest of mediocrity” and substituting ill-informed speculation for genuine expertise; and Nicholas Carr’s book “The Shallows” (coming in June), which suggests that increased Internet use is rewiring our brains, impairing our ability to think deeply and creatively even as it improves our ability to multitask.
  • Steven Johnson, a founder of the online magazine Feed, for instance, wrote in an article in The Wall Street Journal last year that with the development of software for Amazon.com’s Kindle and other e-book readers that enable users to jump back and forth from other applications, he fears “one of the great joys of book reading — the total immersion in another world, or in the world of the author’s ideas — will be compromised.” He continued, “We all may read books the way we increasingly read magazines and newspapers: a little bit here, a little bit there.”

  • One of the most profound changes that occurs when modern schooling is introduced into traditional societies around the world is a radical shift in the locus of power and control over learning from children, families, and communities to ever more centralized systems of authority.
  • Once learning is institutionalized under a central authority, both freedom for the individual and respect for the local are radically curtailed.  The child in a classroom generally finds herself in a situation where she may not move, speak, laugh, sing, eat, drink, read, think her own thoughts, or even  use the toilet without explicit permission from an authority figure.
  • In what should be considered a chilling development, there are murmurings of the idea of creating global standards for education – in other words, the creation of a single centralized authority dictating what every child on the planet must learn.
  • ...26 more annotations...
  • In “developed” societies, we are so accustomed to centralized control over learning that it has become functionally invisible to us, and most people accept it as natural, inevitable, and consistent with the principles of freedom and democracy.   We assume that this central authority, because it is associated with something that seems like an unequivocal good – “education” – must itself be fundamentally good, a sort of benevolent dictatorship of the intellect. 
  • We endorse strict legal codes which render this process compulsory, and in a truly Orwellian twist, many of us now view it as a fundamental human right to be legally compelled to learn what a higher authority tells us to learn.
  • And yet the idea of centrally-controlled education is as problematic as the idea of centrally-controlled media – and for exactly the same reasons.
  • The First Amendment of the U.S. Constitution was designed to protect all forms of communication, information-sharing, knowledge, opinion and belief – what the Supreme Court has termed “the sphere of intellect and spirit” – from government control.
  • by the mid-19th century, with Indians still to conquer and waves of immigrants to assimilate, the temptation to find a way to manage the minds of an increasingly diverse and independent-minded population became too great to resist, and the idea of the Common School was born.
  • We would keep our freedom of speech and press, but first we would all be well-schooled by those in power.
  • A deeply democratic idea — the free and equal education of every child — was wedded to a deeply anti-democratic idea — that this education would be controlled from the top down by state-appointed educrats.
  • The fundamental point of the Occupy Wall Street movement is that the apparatus of democratic government has been completely bought and paid for by a tiny number of grotesquely wealthy individuals, corporations, and lobbying groups.  Our votes no longer matter.  Our wishes no longer count.  Our power as citizens has been sold to the highest bidder.
  • Our kids are so drowned in disconnected information that it becomes quite random what they do and don’t remember, and they’re so overburdened with endless homework and tests that they have little time or energy to pay attention to what’s happening in the world around them.
  • If in ten years we can create Wikipedia out of thin air, what could we create if we trusted our children, our teachers, our parents, our neighbors, to generate community learning webs that are open, alive, and responsive to individual needs and aspirations?  What could we create if instead of trying to “scale up” every innovation into a monolithic bureaucracy we “scaled down” to allow local and individual control, freedom, experimentation, and diversity?
  • The most academically “gifted” students excel at obedience, instinctively shaping their thinking to the prescribed curriculum and unconsciously framing out of their awareness ideas that won’t earn the praise of their superiors.  Those who resist sitting still for this process are marginalized, labeled as less intelligent or even as mildly brain-damaged, and, increasingly, drugged into compliance.
  • the very root, the very essence, of any theory of democratic liberty is a basic trust in the fundamental intelligence of the ordinary person.   Democracy rests on the premise that the ordinary person — the waitress, the carpenter, the shopkeeper — is competent to make her own judgments about matters of domestic policy, international affairs, taxes, justice, peace, and war, and that the government must abide by the decisions of ordinary people, not vice versa.  Of course that’s not the way our system really works, and never has been.   But most of us recall at some deep level of our beings that any vision of a just world relies on this fundamental respect for the common sense of the ordinary human being.
  • This is what we spend our childhood in school unlearning. 
  • If before we reach the age of majority we must submit our brains for twelve years of evaluation and control by government experts, are we then truly free to exercise our vote according to the dictates of our own common sense and conscience?  Do we even know what our own common sense is anymore?
  • We live in a country where a serious candidate for the Presidency is unaware that China has nuclear weapons, where half the population does not understand that Saddam Hussein had nothing to do with 9/11, where nobody pays attention as Congress dismantles the securities regulations that limit the power of the banks, where 45% of American high school students graduate without knowing that the First Amendment of the Constitution guarantees freedom of the press.   At what point do we begin to ask ourselves if we are trying to control quality in the wrong way?
  • Human beings, collaborating with one another in voluntary relationships, communicating and checking and counter-checking and elaborating and expanding on one another’s knowledge and intelligence, have created a collective public resource more vast and more alive than anything that has ever existed on the planet.
  • But this is not a paeon to technology; this is about what human intelligence is capable of when people are free to interact in open, horizontal, non-hierarchical networks of communication and collaboration.
  • Positive social change has occurred not through top-down, hierarchically controlled organizations, but through what the Berkana Institute calls “emergence,” where people begin networking and forming voluntary communities of practice. When the goal is to maximize the functioning of human intelligence, you need to activate the unique skills, talents, and knowledge bases of diverse individuals, not put everybody through a uniform mill to produce uniform results. 
  • You need a non-punitive structure that encourages collaboration rather than competition, risk-taking rather than mistake-avoidance, and innovation rather than repetition of known quantities.
  • if we really want to return power to the 99% in a lasting, stable, sustainable way, we need to begin the work of creating open, egalitarian, horizontal networks of learning in our communities.
  • They are taught to focus on competing with each other and gaming the system rather than on gaining a deep understanding of the way power flows through their world.
  • And what could we create, what ecological problems could we solve, what despair might we alleviate, if instead of imposing our rigid curriculum and the destructive economy it serves on the entire world, we embraced as part of our vast collective intelligence the wisdom and knowledge of the world’s thousands of sustainable indigenous cultures?
  • They knew this about their situation: nobody was on their side.  Certainly not the moneyed classes and the economic system, and not the government, either.  So if they were going to change anything, it had to come out of themselves.
  • As our climate heats up, as mountaintops are removed from Orissa to West Virginia, as the oceans fill with plastic and soils become too contaminated to grow food, as the economy crumbles and children go hungry and the 0.001% grows so concentrated, so powerful, so wealthy that democracy becomes impossible, it’s time to ask ourselves; who’s educating us?  To what end?  The Adivasis are occupying their forests and mountains as our children are occupying our cities and parks.  But they understand that the first thing they must take back is their common sense. 
  • They must occupy their brains.
  • Isn’t it time for us to do the same?
  • Andrew McCluskey on 11 Feb 13
     
    Carol Black, creator of the documentary, "Schooling the World" discusses the conflicting ideas of centralized control of education and standardization against the so-called freedom to think independently--"what the Supreme Court has termed 'the sphere of intellect and spirit" (Black, 2012). Root questions: "who's educating us? to what end?" (Black, 2012).

  • Fractions are as easy as pigs
  • One way to help students to understand the basics of adding and subtracting fractions (denominators must be the same; add/subtract the numerators; DO NOT add/subtract the denominators) is to teach the students what the parts of a fraction really are: numbers and names. This also helps combat the frequently-taught but incorrect idea that a fraction and a ratio are the same. A ratio may look like a fraction, but it is not a fraction.
  • FRACTIONS ARE AS EASY AS PIGS What is 2 pigs plus 3 pigs? 5 pigs (Write as a fraction: 2/pigs + 3/pigs = 5/pigs) Notice, we do not end up saying the answer is 5 horses.
  • ...10 more annotations...
  • The top of a fraction is a NUMBER: 1, 2, 3, etc. The bottom of a fraction is a NAME: half, third, fourth, etc. We can add and subtract numbers. We cannot add and subtract names.
  • Fraction Blackjack
  • Ask each student their "denominator." Don't give it away. Ask each one until one finally says their name. Continue through the room... Their name is their denominator. When you practice adding and subtracting fractions with like denominators, actually say "pigs" instead the fraction name. Then say, "Instead of pigs, we are using ..." and let them answer with the appropriate denominator. It is fun when doing subtraction to say, "If we have 5 pigs and eat 3 pigs, besides a stomachache, what is left?"
  • The transition to unlike denominators is automatic. If the names are not the same, you can't add the fractions. 2/pigs + 3 horses is still 2/pigs and 3/horses (unless we discover a "common denominator" -- a common name: farm animals). Once the students know they must have a common name (denominator) in order to add or subtract, they have a reason to learn about common denominators. By the way, I always begin common denominators without worrying about the Least Common Denominator (LCD). Once they can find a common denominator (multiply the denominators), add or subtract, and then reduce, they can be led to finding "easier" denominators to work with. Students who have too much difficulty with LCD can still get the correct answer; they just have more reducing to do. Those who can find a lower common denominator have less reducing. This is a very basic rendering of "Fractions are as easy as pigs." AWP, 10/12/00 on teachers.net math board
  • Denominate means: to name Political parties nominate (name) their candidates. Religious denominations are identified by their names. The denominations of money are the names of the coins and bills.
  • One game that my students enjoy the challenge of is Blackjack 1. You need a set of fraction cards per student (or you can make them from index cards.) The same rules as Blackjack apply. Instead of trying to get to 21, they want to try and get close to 1 without going over. With this game they practice addition and comparing -- it's great. You can also make it more challenging or bring in mixed numbers with Blackjack 2 or Blackjack 3. (Blackjack 2 means to try to get as close to 2 as possible without going over.) I am not sure where to buy fraction cards. I have one set that I received when I took over a classroom. However, I have always had the students create their own sets and we used them for several games. I gave each students a set of index cards (3 1/2 X 5) and they wrote the fractions in pencil so they couldn't be seen through the cards. These are the fractions we included: all fractions with a denominator of 2, 3, 4, 5, 6, 8, 10, and 12. (To challenge the students you may want to use the 7, 9, and 11 denominators as well.) I also had the students include 2 0's such as 0/3 and 0/4 and two 1's such as 3/3 and 4/4. Each game required two sets of cards, so I had the students write their initials in the corner of their set so they would get a complete set back after the game.

  • I remembered some
  • other
  • Fraction War Fraction War with the fraction cards: It is just like the card game of War, but with the fraction cards instead. This game helps students to compare fractions and encourages them to use number sense in comparison before using the algorithm of making equivalent fractions. Memory Memory with the fraction cards: It is just like the traditional "Memory" game, but any equivalent fractions are considered a match so 1/2 would be a match with 2/4. This game helps them to identify equivalent fractions. You can also play this game with fraction to decimal equivalence by making a set of decimal cards too. Fraction/Decimal Bingo Fraction/Decimal Bingo: The students have game boards with decimals on them. You call out fractions and if they have the decimal equivalence they can mark it on the board.

  • The Method of Loci (plural of Latin locus for place or location), also called the memory palace, is a mnemonic device introduced in ancient Roman and Greek rhetorical treatises (in the anonymous Rhetorica ad Herennium, Cicero's De Oratore, and Quintilian's Institutio oratoria). The items to be remembered in this mnemonic system are mentally associated with specific physical locations.[1] It relies on memorized spatial relationships to establish, order and recollect memorial content. The term is most often found in specialised works on psychology, neurobiology and memory, though it was used in the same general way at least as early as the first half of the nineteenth century in works on rhetoric, logic and philosophy.[2]

      Rubbish. Teachers need to teach. These vacuous ideas that students know as much as teachers and we all teach each other have led to a dangerous decline in educational standards in the West. People do not process in a vacuum; they need to know the content before they can engage in that 'higher-order thinking' Blooms gunk. These theories are an excuse for teachers who don't know their subjects to feel less shamed at their ignorance.

  • what can policy do to limit inequality? The answer is, it can operate on two fronts. It can engage in redistribution, taxing high incomes and aiding families with lower incomes. It can also engage in what is sometimes called “predistribution,” strengthening the bargaining power of lower-paid workers and limiting the opportunities for a handful of people to make giant sums.
  • We can see this in our own history. The middle-class society that baby boomers like me grew up in didn’t happen by accident; it was created by the New Deal, which engineered what economists call the “Great Compression,” a sharp reduction in income gaps.
  • Obamacare provides aid and subsidies mainly to lower-income working Americans, and it pays for that aid partly with higher taxes at the top. That makes it an important redistributionist policy — the biggest such policy since the 1960s.
  • ...4 more annotations...
  • between those extra Obamacare taxes and the expiration of the high-end Bush tax cuts made possible by Mr. Obama’s re-election, the average federal tax rate on the top 1 percent has risen quite a lot. In fact, it’s roughly back to what it was in 1979, pre-Ronald Reagan, something nobody seems to know.
  • What about predistribution? Well, why is Mr. Trump, like everyone in the G.O.P., so eager to repeal financial reform? Because despite what you may have heard about its ineffectuality, Dodd-Frank actually has put a substantial crimp in the ability of Wall Street to make money hand over fist.
  • these medium-size steps put the lie to the pessimism and fatalism one hears all too often on this subject. No, America isn’t an oligarchy in which both parties reliably serve the interests of the economic elite.
  • Money talks on both sides of the aisle, but the influence of big donors hasn’t prevented the current president from doing a substantial amount to narrow income gaps — and he would have done much more if he’d faced less opposition in Congress.

  • raction Hunt Posted by:lismac #130700 Please Signin We walked around the school in small groups armed with cameras and looked for fractions occuring in our school. Each child had to find one scene to capture with the camera. Another group stayed in the classroom and created their fractions with classroom materials. Example- 10 pencils. 9 were yellow and one was red. Then the small groups would come to our computer and insert their picture. Each child then inserted text boxes to type in the fractions. Example- 9/10 of the pencils are yellow. 1/10 of the pencils are red. 9/10 + 1/10= 10/10 They could choose the fonts and colors and such... they used word art to add their names. They loved it!

  • One activity that went over pretty well with my class was putting fractions in order. After completing a lesson on comparing fractions, each student was given a fraction on a 3x5 card and asked to tape it to their chest. Then they were instructed to line up in order from greatest to least. After they had completed the task, after much deliberation, I informed them of the correct order. They did pretty well considering there were fifteen students.

  • Another thing I did was draw fractions number lines (about seven inches long) on a piece of paper, one under another with enough space between lines so my students could label the points. The first line was not divided. The points were labeled 0 and 1. The second line was divided into halves. The students labeled the points on the line 0/2, 1/2, and 2/2. The third line was divided into thirds. The students labeled the points 0/3, 1/3, 2/3, 3/3. You probably get the idea. The remaining lines were divided into fourths, fifths, sixths, eighths, tenths, and twelfths, and the points were labeled. (It is very...
  • I created an interactive fraction number line from 0 to 2 on my wall. I have about 40 fraction cards with different fractions and I have students take turns putting the cards on the number line. They get the chance to see that some of the fractions are equivelent to others.
  • Well, you are not alone. Fractions lessons sometimes need repeating over and over until they understand the CONCEPTS. Try giving them a mnemonic device to help them remember what to do. My kids decided to use GCF as Greatest Calories n Fat so that's why you REDUCE!! This just helped them to know when to use the GCF but it still needs lots of practice. Also, do a lot of hands-on activities that show equivalency in fractions. Make fraction strips using construction paper, and the kids can show all the equivalent fractions by matching up the strips. Or try the pizza fraction pieces that you can buy. I believe that it just takes lots of fun practice as well as drills on the procedures. Take your time and don't rush through it or you'll be sorry to see that they won't remember any of it by Christmas!!
  • Make up index cards before hand. Group them in 3's (.25 on one card, 1/4 on another, 25% on the third) make up however many sets of three you need to give a card to each of the students in your class. Once the cards have been shuffled, pass one to each student. Have them find their 'family' WITHOUT MAKING A SOUND. When .20, 1/5 and 20% find each other they have to put their cards on a large number line in the front of the class. It's a great way to get them all involved, and gets them up and around the classroom.
  • I also have my student play Fraction Tic Tac Toe, on a 4 x 4 grid filled with halves, fourths, and eighths. They have to make a whole with 3 fractions in a row. They love it!!! I'm not sure where the gamesheet come from, but I am sure you can make your own.

In a science class, for example, students should develop a deep understanding of the need for controlled experiments. In a humanities class, they need to learn the classical techniques of rhetoric and develop basic persuasive skills. The curriculum then builds from that foundation.

    "Joyce Valenza Ph.D On the librarian: What's the point . . ? The Twitter conversation April 30, 2009 @karlfisch: What's the point of having a media specialist if they aren't specialists in the media forms of the day? I was nearly finished copying and pasting, figuring out how best to post Tuesday's Twitter conversation, when I discovered that Karl Fisch (@karlfisch), who kinda started it all, already took care of that. (You likely know of Karl's very popular and provocative videos.) I am still not sure how best to frame this conversation on the place of the information/media specialist in today's school. What is clear is that a lot of smart people--people who are out there teaching, speaking, moving, and shaking--are disappointed in what they see when they see school librarians. Either we have a perception problem or we need to do some serious retooling. I'd say we have to deal with both. In a hurry. Being an information (or media) specialist today means being an expert in how information and media flow TODAY! It is about knowing how information and media are created and communicated. How to evalute, synthesize, and ethically use information and media in all their varied forms. It is about being able to communicate knowlege in new ways for new audiences using powerful new information and communication tools. Forgive me if it hurts. In my mind, if you are not an expert in new information and communication tools, you are NOT a media specialist for today. Tuesday's conversation happened in the open, on Twitter. We need to be aware that these conversations are happening where we cannot hear them--at conferences, at Board and cabinet meetings. We also need to make sure that our voices are heard and that we hear the voices of others in places like Twitter, where so many educational leaders and thinkers are chatting about us and many other things. I've selected the remarks that resonated loudest for me. (I've shuffled a bit, but you can visit Karl'

    Inspired by the popular campus game Humans vs. Zombies, join @Jessifer and @allistelling for an epic zombiefied experiment in Twitter literacy, gamification, collaboration, and emergent learning. Part flash-mob. Part Hunger-Games. Part Twitter-pocalypse. Part digital feeding frenzy. Part micro-MOOC. Part giant game of Twitter tag. Band together your most trusted Twitter allies to defend against a virtual Zombie horde. Collect canned goods, store water, watch your hashtags, and sleep with one eye open. THE RULES TO JOIN THE GAME: Register on this page. Commit to posting at least 10 tweets per day. THEN, TO PLAY: 1. A ZOMBIE can #bite (to attack) once every 30 minutes. A bite will turn a HUMAN to a ZOMBIE in exactly five minutes. A #bite can only be sent to a player who has been active on Twitter in the last five mins. 2. A HUMAN can #dodge (protect yourself) once per hour and #swipe (protect someone else) once per hour. 3. When you are bitten, you have five mins to reply to the ZOMBIE with #dodge or have another player reply to you and the zombie with #swipe. A turned HUMAN must update the Twitter vs. Zombies Scoreboard by changing his/her status to ZOMBIE. 4. The rules are emergent. There will be challenges, amendments, and rule adaptations as suggested by the community and implemented by administrators. Keep your eyes on the blog and #TvsZ for updates. Anatomy of an action tweet: [@name(s)] [body of tweet with action tag #bite, #dodge, or #swipe playfully inserted] [game tag: #TvsZ] Example of a bite/dodge: @DigiWriMo attacks: "@moocmooc I want to #bite your lovely flesh. #TvsZ @moocmooc dodges: "@DigiWriMo No you don't. I have not used #dodge in an hour. #TvsZ Example of a bite/swipe: @DigiWriMo attacks: "@moocmooc What's that lump on your neck? Is that some kind of #bite? #TvsZ @Jessifer defends: "@DigiWriMo @moocmooc I #swipe your hungry beak. [pets @moocmooc] #TvsZ The game is beta, and we will be crowd-sourcing the rules as it's played.

  • looking at the Federal Reserve’s quantitative easing program, growth of lower paying jobs, baby boomers retiring, and the massive amount of excess housing inventory we start to see why Japan’s post-bubble real estate market is very likely to occur in the United States.

  • both economies had extraordinarily large real estate bubbles.
  • Massive real estate bubble (check) -Central bank bailing out banks (check) -Bailed out banks keep bad real estate loans on their books at inflated values (check) -Government taking on higher and higher levels of debt relative to GDP (check) -Employment situation stabilizes with less secure labor force (check) -Home prices remain stagnant (check)
  • the United States had never witnessed a year over year drop in nationwide home prices since the Great Depression.
  • home prices are now back to levels last seen 8 years ago.  The lost decade is now nipping at our heels but what about two lost decades like Japan?
  • the U.S. has such a large number of part-time workers and many of the new jobs being added are coming in lower paying sectors signifies that our economy is not supportive of the reasons that gave us solid home prices for many decades. 
  • young Japanese workers, some in their late 20s or early 30s, already resigned that they would never buy a home.
  • The notion that housing is always a great investment runs counter to what they saw in their lives.  Will they even want to buy as many baby boomers put their larger homes on the market
  • many of our young households here are now coming out with massive amounts of student loan debt.
  • Lower incomes, more debt, and less job security.  What this translated to in Japan was stagnant home prices for 20 full years.  We are nearing our 10 year bear market anniversary in real estate so another 10 is not impossible.  What can change this?  Higher median household incomes across the nation but at a time when gas costs $4 a gallon, grocery prices are increasing, college tuition is in a bubble, and the financial system operates with no reform and exploits the bubble of the day, it is hard to see why Americans would be pushing home prices higher.

    New report from Center on Education and the Workforce, Georgetown University, September 2012, by Anthony P. Carnevale, Tamara Jayasundera, Andrew R. Hanson - Daniela Fairchild of the Thomas B. Fordham Institute writes in The Education Gadfly Weekly: "At 31 percent, the United States currently ranks second among OECD nations-behind Norway-for the percentage of its workforce with a four-year college education. That's the good news. The bad news is that we rank sixteenth for the percentage of our workforce with a sub-baccalaureate education (think: postsecondary and industry-based certificates, associate's degrees). Yet a swath of jobs in America calls for just that sort of preparation, which often begins in high school. Dubbed "middle jobs" in this report by the Center on Education and the Workforce, these employment opportunities pay at least $35,000 a year and are divided among white- and blue-collar work. Yet they are largely ignored in our era of "college for all." In two parts, this report delineates five major categories of career and technical education (CTE), then lists specific occupations that require this type of education. It's full of facts and figures and an excellent resource for those looking to expand rigorous CTE in the U.S. Most importantly, it presents this imperative: Collect data on students who emerge from these programs. By tracking their job placements and wage earnings, we can begin to rate CTE programs, shutter those that are ineffective, and scale up those that are successful. If CTE is ever to gain traction in the U.S.-and shed the stigma of being low-level voc-tech education for kids who can't quite make it academically-this will be a necessary first step."

  • But when the results from the first major international math test came out in 1967, the effort did not seem to have made much of a difference. Japan took first place out of 12 countries, while the United States finished near the bottom.
  • By the early 1970s, American students were ranking last among industrialized countries in seven of 19 tests of academic achievement and never made it to first or even second place in any of them. A decade later, "A Nation at Risk," the landmark 1983 report by the National Commission on Excellence in Education, cited these and other academic failings to buttress its stark claim that "if an unfriendly foreign power had attempted to impose on America the mediocre educational performance that exists today, we might well have viewed it as an act of war."

      People use crises to advance their own agendas...
  • But don't expect any of them to bring the country back to its educational golden age -- there wasn't one.
  • According to the most recent statistics, the U.S. share of foreign students fell from 24 percent in 2000 to just below 19 percent in 2008. Meanwhile, countries like Australia, Canada, and Japan saw increased market shares from their 2000 levels, though they are still far below the American numbers.
  • And even with its declining share, the United States still commands 9 percentage points more of the market than its nearest competitor, Britain.
  • A 2008 Rand Corp. report found that nearly two-thirds of the most highly cited articles in science and technology come from the United States, and seven in 10 Nobel Prize winners are employed by American universities. And the United States spends about 2.9 percent of its GDP on postsecondary education, about twice the percentage spent by China, the European Union, and Japan in 2006.
  • But over the long term, exactly where countries sit in the university hierarchy will be less and less relevant, as Americans' understanding of who is "us" and who is "them" gradually changes. Already, a historically unprecedented level of student and faculty mobility has become a defining characteristic of global higher education. Cross-border scientific collaboration, as measured by the volume of publications by co-authors from different countries, has more than doubled in two decades.

    by Emily C. Weinstein, Harvard University International Journal of Communication 8 (2014), 210-233. Social media have dramatically altered the communication landscape, offering novel contexts for individual expression. But how do youth who are civically engaged off-­line manage opportunities for civic expression on social media? Interviews with 70 U.S.-­based civic youth aged 15 to 25 revealed three main patterns characterizing the relationship between off-­line participation and online expression: blended, bounded, and differentiated. Five sets of empirically derived considerations influencing expression patterns emerged: organizational policies, personal image and privacy, perceived alignment with civic goals, attitudes toward the platform(s), and perceptions of their audience(s). Most civic youth express the civic online, yet a minority highlight tensions that lead them to refrain from sharing in certain or all online context.

    COURSE OBJECTIVES: This is a graded internship that allows you to integrate your own coursework with a hands-on service learning experience. The central objective of this course is to provide students with community experiences and reflection opportunities that examine community needs, the importance of civic engagement, and social justice issues affecting ethnic minorities and marginalized populations in contemporary American society. Students dedicate 70 hours at a pre-approved site (including Title I K-12 schools, youth programs, health services, social services, environmental programs, government agencies, etc.) directly serving a population in need or supporting activities that contribute to the greater good of our community. A weekly seminar, course readings, discussions, and reflection assignments facilitate critical thinking and a deeper understanding of cultural diversity, citizenship, and how to contribute to positive social change in our community. The course is also designed to provide "real-world" experiences that exercise academic skills and knowledge applicable to each student‟s program of study and career exploration. STUDENT LEARNING OBJECTIVES: Student will be introduced to essential skills associated with their baccalaureate studies to actively serve the local community. While completing this in-depth study of cultural diversity, citizenship and social justice issues facing our community, students will gain an understanding of the value of Social Embeddedness and the importance of incorporating civic engagement into their collegiate careers, as they strive to become civically engaged students. Students will be introduced to inequalities, discrimination, and other community issues facing ethnic minorities and marginalized populations, as well as the correlation with greater societal issues. INTERNSHIP RESPONSIBILITIES:  Service hours - 70 hours of community outreach (spread throughout the semester in which you are enrolled in the course)
