 Educación. Las 3 Claves del Éxito de los Mejores Sistemas Educativos del Mundo by @ZascaNinja     Al preguntar ¿cuál es el mejor sistema educativo del mundo?, las voces se levantan en coro, casi al unísono clamando por Finlandia; y si bien es cierto que este país del norte de Europa que ha dedicado gran parte de su presupuesto y esfuerzo a promover una educación de calidad que permita al alumno resolver problemas y desarrollar sus propias habilidades ha destacado en el rendimiento académico durante la última década, su lugar de supremacía parece estar llegando a su fin. Ganador indiscutible en la prueba PISA en las ediciones de 2000, 2003 y 2006, para el año 2012 Finlandia pierde su trono a expensas del ascenso de los sistemas educativos asiáticos, ocupando los siete primeros puestos como los mejores sistemas educativos calidad-educaciondel mundo, los de Shanghái, Singapur, Hong Kong, Taiwán, Corea del Sur, Macao y Japón. El ascenso de estos países no tiene porque significar un detrimento del sistema finés sino una evolución rápida y progresiva de sus contra partes asiáticos, algo que con el tiempo tanto en Finlandia como en el resto del mundo se deberá trabajar, haciendo evolucionar así mismo el sistema educativo a las necesidades del nuevo milenio. Aún así y a pesar de las diferencias, cuando se hace un análisis detallado de los elementos en común entre los mejores sistemas educativos del mundo (el finés incluido) llaman la atención tres elementos casi constantes que parecen ser la clave del éxito educativo de todos estos países y que, lejos de ser sistemas complicados de control y planes de estudio, evaluaciones exigentes o metas muy elevadas para cada nivel de la educación, parecen centrarse en el principal activo de la educación: Los maestros y profesores.

Cómo leer grupos de palabras

Una práctica muy sencilla que siempre recomiendo son las señales. Son el ejemplo perfecto sobre cómo leer en bloque, captando el significado de un sólo vistazo y, además, un ejercicio que puedes hacer mientras caminas por la calle. Sin embargo, enfrentarse a un texto Algunos de los beneficios… Expande tu campo de visión Reduce las fijaciones y paradas La atención se centra en nombres y verbos Ignoras palabras ‘complementarias’ Reduce los malos hábitos de lectura Combina múltiples estrategias de lectura rápida Para empezar con esta técnica yo recomiendo comenzar con sesiones de 10-15 minutos al día, empezando por dos palabras. Este es el nivel ideal para estimular tu cerebro y comenzar a procesar más palabras por minuto. Aunque te resulte fácil, no pases al siguiente nivel sin haber pasado primero por este. Los siguientes niveles serían 4-5 para el intermedio y 6-8 en el avanzado. Mostrar detalle

Physics

He is known for his work regarding black holes

He is known for his work regarding black holes     Early Life and Background The eldest of Frank and Isobel Hawking's four children, Stephen William Hawking was born on the 300th anniversary of the death of Galileo—long a source of pride for the noted physicist—on January 8, 1942. He was born in Oxford, England, into a family of thinkers. His Scottish mother had earned her way into Oxford University in the 1930s—a time when few women were able to go to college. His father, another Oxford graduate, was a respected medical researcher with a specialty in tropical diseases. Stephen Hawking's birth came at an inopportune time for his parents, who didn't have much money. The political climate was also tense, as England was dealing with World War II and the onslaught of German bombs. In an effort to seek a safer place, Isobel returned to Oxford to have the couple's first child. The Hawkings would go on to have two other children, Mary (1943) and Philippa (1947). And their second son, Edward, was adopted in 1956. The Hawkings, as one close family friend described them, were an "eccentric" bunch. Dinner was often eaten in silence, each of the Hawkings intently reading a book. The family car was an old London taxi, and their home in St. Albans was a three-story fixer-upper that never quite got fixed. The Hawkings also housed bees in the basement and produced fireworks in the greenhouse. In 1950, Hawking's father took work to manage the Division of Parasitology at the National Institute of Medical Research, and spent the winter months in Africa doing research. He wanted his eldest child to go into medicine, but at an early age, Hawking showed a passion for science and the sky. That was evident to his mother, who, along with her children, often stretched out in the backyard on summer evenings to stare up at the stars. "Stephen always had a strong sense of wonder," she remembered. "And I could see that the stars would draw him." Early in his academic life, Hawking, while recognized as bright, was not an exceptional student. During his first year at St. Albans School, he was third from the bottom of his class. But Hawking focused on pursuits outside of school; he loved board games, and he and a few close friends created new games of their own. During his teens, Hawking, along with several friends, constructed a computer out of recycled parts for solving rudimentary mathematical equations. Hawking was also frequently on the go. With his sister Mary, Hawking, who loved to climb, devised different entry routes into the family home. He remained active even after he entered University College at Oxford University at the age of 17. He loved to dance and also took an interest in rowing, becoming a team coxswain. Hawking expressed a desire to study mathematics, but since Oxford didn't offer a degree in that specialty, Hawking gravitated toward physics and, more specifically, cosmology. By his own account, Hawking didn't put much time into his studies. He would later calculate that he averaged about an hour a day focusing on school. And yet he didn't really have to do much more than that. In 1962, he graduated with honors in natural science and went on to attend Trinity Hall at Cambridge University for a PhD in cosmology.

Know the Association for Women in Mathematics

Know the Association for Women in Mathematics     We aim to encourage and support women in the specific discipline of mathematics. In particular, we would like to bring together women undergraduates, graduates and members of faculty in the mathematics department, to provide mutual support and to increase the visibility of women in mathematics. Some planned activities of our organization include having speakers, either from the U of C community or elsewhere, to discuss issues relating to women in math, running a mentoring program for women in math, and providing online resources for women in math.

Maxwell Herman Alexander Newman

Newman also wrote an important paper on theoretical computer science, produced a topological counter-example of major significance in collaboration with Henry Whitehead, and wrote an outstanding paper on periodic transformations in abelian topological groups. He only wrote one book Elements of the topology of plane sets of points (1939). Writing in [4], Peter Hilton claims that:- ... this is the only text in general topology which can be wholeheartedly recommended without qualification. It is beautifully written in the limpid style one would expect of one who combined clarity of thought, breadth of view, depth of understanding and mastery of language. Newman saw, and presented, topology as part of the whole of mathematics, not as an isolated discipline: and many must wish he had written more. In 1962 Newman was presented with the De Morgan Medal from the London Mathematical Society. The President of the Society, Mary Cartwright, gave a tribute to Newman's work which is reported in [3]:- His early work on Combinatory Topology has exercised a decisive influence on the development of that subject. At a time when the study of manifolds was based on a number of different combinatory concepts, he established a simple combinatory system of simplicial complexes with an equivalence relation based on elementary moves. ... He has proved two important results about fixed points. The first was an early inroad on Hilbert's Fifth Problem, in which he proved that abelian continuous groups do not have arbitrarily small subgroups, the second was a simplified proof of a difficult fixed point theorem of Cartwright and Littlewood arising in the study of differential equations. ... In 1964 Newman retired from his Manchester chair but he most certainly did not give up mathematics. He taught a course at the University of Warwick and at this time I [EFR] was a research student there and met him and attended lectures he gave. He was an outstanding teacher, clearly giving much attention to the organisation of his material. Retirement was also an opportunity for Newman to relaunch his research career which he did with the vigour of a young academic. He published a highly significant paper in 1966 which proved the Poincaré Conjecture for topological manifolds of dimension greater than 4. Lynn Newman died in 1973, and later in the same year he married Margaret Penrose, the daughter of a professor of physiology, who was the widow of the physician Professor Lionel Sharples Penrose.

Autism

Brain connections in people with autism show more symmetry between hemispheres. @SDSU

Brain connections in people with autism show more symmetry between hemispheres. @SDSU     Divvying up tasks between the left and right hemispheres of the brain is one of the hallmarks of typical brain development. The left hemisphere, for instance, is involved in analyzing specific details of a situation, while the right hemisphere is more important for integrating all the various streams of information coming into the brain. A new study by neuropsychologists at San Diego State University suggests that in children and adolescents with autism spectrum disorder (ASD), the brains’ hemispheres are less likely to specialize one way or another. The finding gives further insight into how brain development in people with ASD contributes to the disorder’s cognitive characteristics. Mostrar detalle

Correlation

The Development of Correlation and Association in Statistics

The Development of Correlation and Association in Statistics     The Development of Correlation and Association in Statistics Jake D. Brutlag fifth revision 12/15/07 The object of statistical science is to discover methods of condensing information concerning large groups of allied facts into brief and compendious expressions suitable for discussion --Sir Francis Galton (1822-1911) One historical motivation for the field of statistics was to capture the meaning of data in "brief and compendious expressions." It is one thing to glance at a table of numbers and claim "I see some meaning here"; it is quite another to demonstrate such a table constitutes evidence for a particular conclusion. In the study of two random variables measured in the same sample, correlation measures the degree to which the two measures are linearly related. A related concept is the regression model, in which the goal is to find a linear equation that best predicts the value of one variable (or measurement), given the value of the other variable. The best estimate of the slope in the regression model, y = b(x) + a, is related to the correlation coefficient, r, by: Mostrar detalle
