Scientists pinpoint brain’s math area, important for numeral recognition

Scientists pinpoint brain’s math area, important for numeral recognition | Aprendiendo a Distancia | Scoop.it

Scientists at the Stanford University School of Medicine have determined the precise anatomical coordinates of a brain “hot spot,” measuring only about one-fifth of an inch across, that is preferentially activated when people view the ordinary numerals we learn early on in elementary school, like “6” or “38.”

Activity in this spot relative to neighboring sites drops off substantially when people are presented with numbers that are spelled out (“one” instead of “1”), homophones (“won” instead of “1”) or “false fonts,” in which a numeral or letter has been altered.

“This is the first-ever study to show the existence of a cluster of nerve cells in the human brain that specializes in processing numerals,” said Josef Parvizi, MD, PhD, associate professor of neurology and neurological sciences and director of Stanford’s Human Intracranial Cognitive Electrophysiology Program. “In this small nerve-cell population, we saw a much bigger response to numerals than to very similar-looking, similar-sounding and similar-meaning symbols.

“It’s a dramatic demonstration of our brain circuitry’s capacity to change in response to education,” he added. “No one is born with the innate ability to recognize numerals.”The finding pries open the door to further discoveries delineating the flow of math-focused information processing in the brain. It also could have direct clinical ramifications for patients with dyslexia for numbers and with dyscalculia: the inability to process numerical information.

 

Interestingly, said Parvizi, that numeral-processing nerve-cell cluster is parked within a larger group of neurons that is activated by visual symbols that have lines with angles and curves. “These neuronal populations showed a preference for numerals compared with words that denote or sound like those numerals,” he said. “But in many cases, these sites actually responded strongly to scrambled letters or scrambled numerals. Still, within this larger pool of generic neurons, the ‘visual numeral area’ preferred real numerals to the false fonts and to same-meaning or similar-sounding words.”

It seems, Parvizi said, that “evolution has designed this brain region to detect visual stimuli such as lines intersecting at various angles — the kind of intersections a monkey has to make sense of quickly when swinging from branch to branch in a dense jungle.” The adaptation of one part of this region in service of numeracy is a beautiful intersection of culture and neurobiology, he said.

Having nailed down a specifically numeral-oriented spot in the brain, Parvizi’s lab is looking to use it in tracing the pathways described by the brain’s number-processing circuitry. “Neurons that fire together wire together,” said Shum. “We want to see how this particular area connects with and communicates with other parts of the brain.”

Blubbr: Create interactive quizzes using YouTube clips | Aprendiendo a Distancia | Scoop.it

Blubbr is a neat quiz creation service that I recently learned about on Danny Nicholson's blog. Using Blubbr you can create interactive quizzes that are based on YouTube clips. Your quizzes can be about anything of your choosing. The structure of the quizzes has a viewer watch a short clip then answer a multiple choice question about the clip. Viewers know right away if they chose the correct answer or not.

From a Million MOOC Users, a Few Early Research Results – Wired Campus - Blogs - The Chronicle of Higher Education

From a Million MOOC Users, a Few Early Research Results – Wired Campus - Blogs - The Chronicle of Higher Education | Aprendiendo a Distancia | Scoop.it

Preliminary results of a study of 16 massive open online courses offered through the University of Pennsylvania show that only a small percentage of people who start the courses finish them—and that, on average, only half of those who register for the courses even watch the first lecture.

 

The study, conducted by the university’s Graduate School of Education, is reviewing data from about a million users of the courses, which Penn offered on the Coursera platform, from June 2012 to June 2013. Two of the seven researchers involved—Laura W. Perna, a professor of higher education, and Alan Ruby, senior fellow for international education—described the study on Thursday in a presentation at the MOOC Research Conference now under way in Arlington, Tex.

[eBook] Tendencias emergentes en Educación con TIC

La Asociación Espiral, Educación y Tecnología nos ofrece una valiosa publicación colaborativa que recopila una serie de tendencias metodológicas amparadas en el uso de las TIC.

 

“Tendencias emergentes en Educación con TIC” tiene como finalidad dar a conocer planteamientos pedagógicos y didácticos con Tecnologías de Información y Comunicación  (TIC), llevados y testados en la práctica docente del aula.

 

Este libro ha sido elaborado por un grupo de investigadores españoles que no piden más recompensa que ver publicada su obra, pues la publicación está editada con una licencia Creative Commons y se ha financiado a través de un sistema colectivo (crowdfunding).

 

Si bien algunos casos parten del contexto o de la realidad de España, generalmente, el libro ofrece planteamientos que se adaptan a cualquier realidad.

La publicación contiene quince temas interesantes que ayudan a que se abran las puertas al progreso y a la innovación, dejando de lado el miedo al cambio.

 

Entre los temas que más destacan, podríamos mencionar: Identificación y regulación de emociones con Scratch; Aplicación de las licencias de Creative Commons en el ámbito educativo; El uso de códigos QR en la enseñanza; ¿Qué se aprende de la historia y el paisaje medieval a través de los videojuegos? Un análisis didáctico; y Dispositivos móviles en el aula. El aprendizaje en nuestras manos.

How to create efficient quizzes?

How to create efficient quizzes? | Aprendiendo a Distancia | Scoop.it

Students shouldn’t only be listeners. They should also interact with learning content. Quiz is one of the possible interactions that gives great results for long-term knowledge. There are four basic types of questions: multiple choice, single choice, true/false and fill in the blanks. As I’ll explain, these types serve slightly different purposes, but the main purpose of all quizzes is assessment. You can and should mix it up with different types of questions – as it engages the students mind in multiple ways. There are however some basic principles to follow.
