"This article analyzes teacher strikes in Argentina during 2006-2012. It stands out how teacher strikes prevail over claims from other unions, and are shown to be relevant events for education policy just for some provinces and only for public schools. We found that none of the policy measures implemented over the last decade has proven to be effective in reducing conflict. Analyzing a dataset on labour unrest, this study builds an index of teacher labour conflict to better understand the evolution of teacher strikes over time and under the various provincial governments that integrate the Argentinian federal education system. The article shows no correlation between teacher labour unrest and the growth of private enrolment. However, we note that despite the lack of statistical correlation, teacher strikes should not be ruled out as an explanatory variable of the increase in private education in Argentina."

Who's Asking? - Alfie Kohn - 0 views

"It seems only fitting to explore the role of questions in education by asking questions about the process of doing so. I propose that we start with the customary way of framing this topic and then proceed to questions that are deeper and potentially more subversive of traditional schooling. 1. WHICH QUESTIONS? To begin, let's consider what we might ask our students. The least interesting questions are those with straightforward factual answers. That's why a number of writers have encouraged the use of questions described variously as "true" (Wolf, 1987), "essential" (Simon, 2002), "generative" (Perkins, 1992; Perrone, 1998), "guiding" (Traver, 1998), or "fertile" (Harpaz & Lefstein, 2000). What the best of these share is that they're open-ended. Sometimes, in fact, no definitive right answer can be found at all. And even when there is one - or at least when there is reason to prefer some responses to others - the answer isn't obvious and can't be summarized in a sentence. Why is it so hard to find a cure for cancer? Do numbers ever end? Why do people lie? Why did we invade Vietnam? Grappling with meaty questions like these (which were among those generated by a class in Plainview, NY) is a real project . . . literally. A question-based approach to teaching tends to shade into learning that is problem- (Delisle, 1997) and project-based (Kilpatrick, 1918; Blumenfeld et al., 1991; Wolk, 1998). Intellectual proficiency is strengthened as students figure out how to do justice to a rich question. As they investigate and come to understand important ideas more fully, new questions arise along with better ways of asking them, and the learning spirals upwards. Guiding students through this process is not a technique that can be stapled onto our existing pedagogy, nor is it something that teachers can be trained to master during an in-service day. What's required is a continual focus on creating a classroom that is about thinking rather

These 'warming stripe' graphics are visual representations of the change in temperature as measured in each country over the past 100+ years. Each stripe represents the temperature in that country averaged over a year. For most countries, the stripes start in the year 1901 and finish in 2018. For the UK, USA, Switzerland & Germany, the data starts in the late 19th century.

"Our core ecological problem is not climate change. It is overshoot, of which global warming is a symptom. Overshoot is a systemic issue. Over the past century-and-a-half, enormous amounts of cheap energy from fossil fuels enabled the rapid growth of resource extraction, manufacturing, and consumption; and these in turn led to population increase, pollution, and loss of natural habitat and hence biodiversity. The human system expanded dramatically, overshooting Earth's long-term carrying capacity for humans while upsetting the ecological systems we depend on for our survival. Until we understand and address this systemic imbalance, symptomatic treatment (doing what we can to reverse pollution dilemmas like climate change, trying to save threatened species, and hoping to feed a burgeoning population with genetically modified crops) will constitute an endlessly frustrating round of stopgap measures that are ultimately destined to fail."

"This is a simple tool that uses some basic trigonometry to measure the height of trees. This tool is a 45-45-90 triangle and thus an isosceles triangle. Isosceles triangles have two legs of equal length. By using a 45-45-90 triangle to placed yourself at a distance from a tree trunk, you create an triangle where the distance from the trunk is also the height of the tree. "

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."

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.

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).
