"In Texas, there are 180 days of instruction, taking away 30 days for state testing so that leave 150 days for instruction. Let's say that a teacher gives a curriculum-based test once every two weeks and the district benchmark test three times a year. That is 21 less days of instruction or 129 days. Now, schools typically have three days of teacher in-service. Five special assemblies, two holiday parties, two half days, four emergency drills and three sick days takes away 15 more days bringing it to 111 days."

En este amplio mundo del conocimiento me he encontrado el tema de la historia del ebook del libro que escribió Marie Lebert y traducido por Anna Álvarez, y me pareció interesante por esa razón quiero compartir en forma resumida algunos aspectos sobresalientes del mismo con todos mis lectores. El libro ha cambiado mucho desde 1971. El libro impreso tiene cinco siglos y medio de edad. El libro digital casi tiene 40. Nace con el Proyecto Gutenberg, creado en julio de 1971 por Michael Hart con el fin de distribuir gratuitamente las obras del dominio público por vía electrónica. Pero habrá que esperar hasta el advenimiento de la web y del primer navegador para que el Proyecto Gutenberg encuentre su velocidad de crucero. Señal de los tiempos que corren, en noviembre del año 2000, la British Library pone en línea la versión digital de la Biblia de Gutenberg, el primer libro impreso. Aquella Biblia - datada de 1454 o 1455 -, fue impresa por Gutenberg en 180 ejemplares en su taller de Maguncia, en Alemania.

" In our hyper-connected, 24/7 world, many of us are losing sleep - literally. Our own survey of more than 180 business leaders found that four out of 10 (43%) say they do not get enough sleep at least four nights a week. Such sleep deficiencies can undermine important forms of leadership behavior and eventually hurt financial performance. This article will explore the link between sleep and leadership before discussing solutions that can improve both individual well-being and organizational efficiency and effectiveness."

"I have added a new page to this blog. I called it Notable Links. It compiles many of the teacher generated sites (Estimation 180, WODB etc) as well as many teacher blogs where they often share resources. It's by no means a complete list and I am sure I will miss some but I wanted to have a running list of the best stuff somewhere (if only for me)"

"This December will again host the Hour of Code, a one-hour introduction to programming designed to demystify the subject and show that anyone can be a maker, a creator, and an innovator. Last year, almost 300,000 students (age 4-104) participated from over 180 countries and wrote almost 20 billion lines of code. The 200,000+ teachers involved came away believing that, of all their education tools, coding was the best at teaching children to think. It's easy to see why when you look at fundamental programming concepts:"

"For years, Canadian parents and educators have engaged in passionate debate over how kids learn math. The math wars, especially contentious in Alberta, have pitted "old" math versus "new," or "discovery," math. But Daniel Ansari, of the University of Western Ontario, says it's time to end the wars. The researcher says the evidence shows that the best way to teach math is with elements from both methods. He refers to the two schools as  "procedural learning" and "conceptual learning," and says they can complement each other when taught together. Ansari says he understands why the topic is so contentious, but adds that it doesn't need to be that way. He offers his solutions for educators, and for parents too. "
