Según las Neurociencias, ¿es válida la antinomia constructivismo/conductismo, o estamos frente a dos mecanismos igualmente eficientes, pero aplicables a diferentes tipos de aprendizaje? Las neurociencias han aportado evidencias sobre qué ocurre en el cerebro durante el aprendizaje pero aun no se sabe exactamente cómo ocurre el aprendizaje y cuál es el efecto de las distintas prácticas pedagógicas en el funcionamiento cerebral de los niños. Sí se sabe que el aprendizaje se relaciona con un cambio en las conexiones sinápticas de las neuronas o de un grupo de neuronas específico, y/o con la generación de nuevas sinapsis, que se originan como una respuesta a cambios internos al cerebro y/o a los provenientes del entorno. No existiría una única manera de aprender del cerebro sino que los mecanismos y las áreas cerebrales implicadas difieren de acuerdo con el tipo de información o conocimiento que tengamos que adquirir. No es lo mismo aprender a leer que aprender a sumar y restar, y tampoco lo es el aprender fechas históricas precisas, la tabla periódica, una técnica deportiva o a tocar un instrumento musical. Intervienen distintas regiones cerebrales y se almacenan en diferentes sistemas de memoria. Es por ello que los métodos de enseñanza deberían diferenciarse también según el contenido de que se trate.

Es necesario continuar construyendo puentes de entendimiento entre los investigadores y clínicos que se dedican a las neurociencias cognitivas y los profesionales de la educación a fin de que los hallazgos de las investigaciones puedan traducirse en un lenguaje accesible y en prácticas concretas para el ámbito escolar.

In the 1960s archaeologists from the University of Chicago had surveyed the region and concluded that Göbekli Tepe was of little interest. Disturbance was evident at the top of the hill, but they attributed it to the activities of a Byzantine-era military outpost.

Schmidt had come across the Chicago researchers' brief description of the hilltop and decided to check it out. On the ground he saw flint chips—huge numbers of them. "Within minutes of getting there," Schmidt says, he realized that he was looking at a place where scores or even hundreds of people had worked in millennia past.

s the months and years went by, Schmidt's team

found a second circle of stones, then a third, and then more. Geomagnetic surveys in 2003 revealed at least 20 rings piled together, higgledy-piggledy, under the earth

The pillars were big—the tallest are 18 feet in height and weigh 16 tons. Swarming over their surfaces was a menagerie of animal bas-reliefs, each in a different style, some roughly rendered, a few as refined and symbolic as Byzantine art.

The circles follow a common design. All are made from limestone pillars shaped like giant spikes or capital T's. Bladelike, the pillars are easily five times as wide as they are deep. They stand an arm span or more apart, interconnected by low stone walls. In the middle of each ring are two taller pillars, their thin ends mounted in shallow grooves cut into the floor.

"They hadn't yet mastered engineering." Knoll speculated that the pillars may have been propped up, perhaps by wooden posts.

To Schmidt, the T-shaped pillars are stylized human beings, an idea bolstered by the carved arms that angle from the "shoulders" of some pillars, hands reaching toward their loincloth-draped bellies.

The stones face the center of the circle—as at "a meeting or dance," Schmidt says—a representation, perhaps, of a religious ritual.

As for the prancing, leaping animals on the figures, he noted that they are mostly deadly creatures: stinging scorpions, charging boars, ferocious lions. The figures represented by the pillars may be guarded by them, or appeasing them, or incorporating them as totems.

The site may have been built, filled in, and built again for centuries.

Bewilderingly, the people at Göbekli Tepe got steadily worse at temple building.

The earliest rings are the biggest and most sophisticated, technically and artistically. As time went by, the pillars became smaller, simpler, and were mounted with less and less care. Finally the effort seems to have petered out altogether by 8200 B.C. Göbekli Tepe was all fall and no rise.

If you understand through the learning of language how people think, how they construct meaning, what is important to them culturally, then I think that gives us better insights into the people that we're going to be working with in the future and negotiating with.

Broadly, teachers and education experts have welcomed the plan, but question where the money is going to come from.

Currently across all levels of schooling there's around 18 per cent of our young people who are studying one of the four priority Asian languages: Mandarin Chinese, Japanese, Indonesian and Korean. And that diminishes to fewer than 6 per cent by the time they get to Year 12.

say we simply don't have enough Asian language teachers to deliver the Prime Minister's vision and for the last decade the numbers of graduates have been declining.

hat's happened because universities have been under these budget constraints and when they've made decisions about what to cut, they cut courses with low enrolments and there goes the languages.

What we can do through the National Broadband Network, what we can do through having the world's first online national curriculum, which is what the Australian curriculum is, means we can get a deeper penetration of language, literacy and learning.

we need to be looking very carefully at what sort of encouragement and incentives we can provide to students so they continue doing a language, go on and major in a language in university and then go on to teach in the area.

Archaeologists are still excavating Göbekli Tepe and debating its meaning. What they do know is that the site is the most significant in a volley of unexpected findings that have overturned earlier ideas about our species' deep past. Just 20 years ago most researchers believed they knew the time, place, and rough sequence of the Neolithic Revolution—the critical transition that resulted in the birth of agriculture, taking Homo sapiens from scattered groups of hunter-gatherers to farming villages and from there to technologically sophisticated societies with great temples and towers and kings and priests who directed the labor of their subjects and recorded their feats in written form. But in recent years multiple new discoveries, Göbekli Tepe preeminent among them, have begun forcing archaeologists to reconsider. At first the Neolithic Revolution was viewed as a single event—a sudden flash of genius—that occurred in a single location, Mesopotamia, between the Tigris and Euphrates Rivers in what is now southern Iraq, then spread to India, Europe, and beyond. Most archaeologists believed this sudden blossoming of civilization was driven largely by environmental changes: a gradual warming as the Ice Age ended that allowed some people to begin cultivating plants and herding animals in abundance. The new research suggests that the "revolution" was actually carried out by many hands across a huge area and over thousands of years. And it may have been driven not by the environment but by something else entirely.

Most of the world's great religious centers, past and present, have been destinations for pilgrimages

Göbekli Tepe may be the first of all of them, the beginning of a pattern. What it suggests, at least to the archaeologists working there, is that the human sense of the sacred—and the human love of a good spectacle—may have given rise to civilization itself.

Puzzle piled upon puzzle as the excavation continued. For reasons yet unknown, the rings at Göbekli Tepe seem to have regularly lost their power, or at least their charm. Every few decades people buried the pillars and put up new stones—a second, smaller ring, inside the first.

There is rarely a moment when I’m not within reach of a firearm.

We don’t touch the guns or draw them from their holsters. They are unseen and unspoken of, but always there.

Rarely do we mention what we carry

They fear that what starts as an assault-weapons ban will snowball into an attack on everything in the safe.

The truth is, there are guns I feel justified in owning and guns I feel belong on battlefields.

I know that part of what they’re missing or refusing to acknowledge is how fear ushered in this shift in gun culture over the past two decades.

Fear is the factor no one wants to address — fear of criminals, fear of terrorists, fear of the government’s turning tyrannical and, perhaps more than anything else, fear of one another.

I recognize this, because I recognize my own and I recognize that despite all I know and believe I can’t seem to overcome it.

I don’t buy into that only-way-to-stop-a-bad-guy-with-a-gun-is-a-good-guy-with-a-gun bravado.

I have no visions of being a hero. Instead, I find myself looking for where I’d run, asking myself what I would get behind. The gun is the last resort. It’s the final option when all else is exhausted.

The fear was lessened by knowing that there was a round chambered, that all it would take is the downward push of a safety and the short pull of a trigger for that bullet to breathe. I felt safer knowing that gun was there.
