B. F. Skinner, referring to the first days of his "teaching machines," in the late 1950s and early 1960s, wrote, "I was soon saying that, with the help of teaching machines and programmed instruction, students could learn twice as much in the same time and with the same effort as in a standard classroom."

a bridge to the twenty-first century ... where computers are as much a part of the classroom as blackboards
-
We could do so much to make education available twenty-four hours a day, seven days a week, that people could literally have a whole different attitude toward learning

Larry Cuban, a professor of education at Stanford University and a former school superintendent, observed that as successive rounds of new technology failed their promoters' expectations, a pattern emerged
-
The promoters of computers in schools again offer prodigious research showing improved academic achievement after using their technology
-
The possibilities of using this thing poorly so outweigh the chance of using it well, it makes people like us, who are fundamentally optimistic about computers, very reticent
-
Perhaps the best way to separate fact from fantasy is to take supporters' claims about computerized learning one by one and compare them with the evidence in the academic literature and in the everyday experiences I have observed or heard about in a variety of classrooms.
-
To make tomorrow's work force competitive in an increasingly high-tech world, learning computer skills must be a priority.
-
Technology programs leverage support from the business community—badly needed today because schools are increasingly starved for funds.
-
Work with computers—particularly using the Internet—brings students valuable connections with teachers, other schools and students, and a wide network of professionals around the globe.

-
n the early 1980s Apple shrewdly realized that donating computers to schools might help not only students but also company sales, as Apple's ubiquity in classrooms turned legions of families into Apple loyalists
-
Apple quickly learned that teachers needed to change their classroom approach to what is commonly called "project-oriented learning
-
Even in success stories important caveats continually pop up. The best educational software is usually complex — most suited to older students and sophisticated teachers.
-
Each chapter describes various strategies for getting computers into classrooms, and the introduction acknowledges that "this report does not evaluate the relative merits of competing demands on educational funding
-
Today's parents, knowing firsthand how families were burned by television's false promises, may want some objective advice about the age at which their children should become computer literate
-
Opinions diverge in part because research on the brain is still so sketchy, and computers are so new, that the effect of computers on the brain remains a great mystery.
-
n the past decade, according to the presidential task force's report, the number of jobs requiring computer skills has increased from 25 percent of all jobs in 1983 to 47 percent in 1993
-
told me the company rarely hires people who are predominantly computer experts, favoring instead those who have a talent for teamwork and are flexible and innovative
-
Many jobs obviously will demand basic computer skills if not sophisticated knowledge. But that doesn't mean that the parents or the teachers of young students need to panic.
-
NEWSPAPER financial sections carry almost daily pronouncements from the computer industry and other businesses about their high-tech hopes for America's schoolchildren
-
High-tech proponents argue that the best education software does develop flexible business intellects
-
IT is hard to visit a high-tech school without being led by a teacher into a room where students are communicating with people hundreds or thousands of miles away — over the Internet or sometimes through video-conferencing systems (two-way TV sets that broadcast live from each room).

The free nature of Internet information also means that students are confronted with chaos, and real dangers

chooling is not about information. It's getting kids to think about information. It's about understanding and knowledge and wisdom

"Our new blog is designed to radically reduce the energy use associated with accessing our content. Low-tech Magazine was born in 2007 and has seen minimal changes ever since. Because a website redesign was long overdue - and because we try to practice what we preach - we decided to build a low-tech, self-hosted, and solar-powered version of Low-tech Magazine. The new blog is designed to radically reduce the energy use associated with accessing our content. Why a Low-tech Website? We were told that the Internet would "dematerialise" society and decrease energy use. Contrary to this projection, it has become a large and rapidly growing consumer of energy itself. In order to offset the negative consequences associated with high energy consumption, renewable energy has been proposed as a means to lower emissions from powering data centers. For example, Greenpeace's yearly ClickClean report ranks major Internet companies based on their use of renewable power sources."

Rang-Tan's Story | Iceland's Banned Palm Oil - 0 views

"Last year I went to West Kalimantan in Borneo to see for myself the effects of the runaway growth of the palm oil industry. I came home firm in the belief that Iceland would not continue using palm oil until companies delivered on their zero deforestation commitments. This is because palm oil has had devastating consequences for local communities, who are being displaced, and on endangered species like the orangutan (our closest relative in the wild), which are being driven close to extinction. Palm oil has many benefits, chiefly that its yields are better than the alternatives. But it is grown almost exclusively in areas of tropical rainforest, which are the 'crown jewels' of our planet's biodiversity. With 146 football pitches of rainforest being lost every hour in Indonesia alone, the urgency of the crisis cannot be overstated. And global demand is set to double by 2050. At Iceland the 1,000 tonnes of palm oil we used annually pale into insignificance compared to many of our competitors. As such a tiny player we took the decision that the only way we could create meaningful change was to shout very loudly from outside the established palm oil industry. So we decided simply to stop using palm oil until the industry cleaned up its act. It was our own decision to give consumers a choice where previously there was none. We never called for a wider industry ban, and accept entirely that a wholesale boycott of palm oil is not the right long term solution. ..."

Exxon Predicted 2019's Ominous CO2 Milestone in 1982 - 0 views

"... The prediction is a pretty damn good one. The world is now about 1 degree Celsius (1.8 degrees Fahrenheit) warmer than it was and carbon dioxide levels are at 415 ppm. The estimate was part of Exxon's "high case" scenario, which assumed fossil fuel use would quicken and that the world would be able to tap new reserves in the late 2000s from at the time unreachable shale gas. The memo also warned that the extra carbon dioxide would enhance the greenhouse effect and that an "increase in absorbed energy via this route would warm the earth's surface causing changes in climate affecting atmospheric and ocean temperatures, rainfall patterns, soil moisture, and over centuries potentially melting the polar ice caps." Honestly, it gave me chills re-reading the memo 37 years later. The company clearly described all the horrors we're facing now. The only thing its scientists got wrong was that what they called "potentially serious climate problems" wouldn't emerge until the late 21st century. So much for that. ..."

"Tres compañías de producción de carne -JBS, Cargill y Tyson- emitieron más gases con efecto de invernadero el año pasado que toda Francia, y casi tanto como algunas de las mayores compañías petroleras, tales como Exxon, BP y Shell. Pocas compañías de carne y lácteos calculan o publican sus emisiones climáticas. Así que, por primera vez en la historia, hemos calculado las emisiones de las corporaciones relacionadas con la cria de animales utilizando la metodología más abarcadora creada hasta la fecha por la Organización de Naciones Unidas de la Agricultura y la Alimentación (FAO)."
