The STEM Teaching Tools site has tools that can help you teach science, technology, engineering and math (STEM). We are currently focused on supporting the teaching of the Next Generation Science Standards (NGSS). Each tool is focused on a specific issue and leverages the best knowledge from research and practice. Under the News section, you can learn a bit more about how you might use them. This article provides background on this effort. Review more resources in our Tools area and check out the online "short courses" shown below.
For what reasons do academics follow one another on Twitter? Robert Jäschke, Stephanie B. Linek and Christian P. Hoffmann analysed the Twitter activity of computer scientists and found that while the quality of information provided by a Twitter account is a key motive for following academic colleagues, there is also evidence of a career planning motive. As well as there being reciprocal following between users of the same academic status (except, remarkably, between PhD researchers), a form of strategic politeness can be observed whereby users follow those of higher academic status without necessarily being followed back. The emerging academic public sphere facilitated by Twitter is largely shaped by dynamics and hierarchies all too familiar to researchers struggling to plot their careers in academia.
The Cape Hatteras National Seashore extends from the town of Nags Head, NC south to Ocracoke Island. Resource preservation efforts are most obvious in the park's miles of undeveloped coastal habitat, but also include several historic sites including three light stations at Bodie Island, Cape Hatteras, and Ocracoke Island.
On August 17, 1586, German theologian, author, and mathematician Johann Valentin Andreae was born. He claimed to be the author of the Chymische Hochzeit Christiani Rosencreutz anno 1459 (1616, Strasbourg, the Chymical Wedding of Christian Rosenkreutz), one of the three founding works of Rosicrucianism, a philosophical secret society said to have been founded in late medieval Germany by Christian Rosenkreutz. Rosicrucianism holds a doctrine or theology "built on esoteric truths of the ancient past", which, "concealed from the average man, provide insight into nature, the physical universe and the spiritual realm."
On December 27, 1822, French chemist Louis Pasteur was born, who is considered one of the most important founders of medical microbiology. He is remembered for his remarkable breakthroughs in the causes and preventions of diseases.
On 13 December 1968, the late Garrett Hardin published an essay in Science that was destined to become one of the journal's most requested articles in the subsequent 35 years. Below, we feature links to the original essay, and some of the scientific dialogue that Hardin's controversial ideas have spurred, as played out in the pages of Science.
On February 15, 1934, Swiss computer scientist Niklaus Emil Wirth was born. He is best known for designing several programming languages, including Pascal, and for pioneering several classic topics in software engineering. If there is (or better 'was') one programming language that I really loved in the same way I hated it, then it was Pascal. On the one hand it was a rather easy to understand beginners programming language, but when trying to build 'real world' software projects based on Pascal, most of them in my experience were doomed to fail. The largest project based on Pascal that I was involved with was a 2 mio lines of code near realtime application for the military back in the 1990s. Everybody knew, we better should have chosen Ada or C++, but it was not our decision to use Pascal. Believe me, you wouldn't like to maintain 2 mio lines of Pascal code. Nevertheless, the concept of the language designed by Niklaus Wirth was a great achievement for computer science!
On March 8, 1931, media theorist, author, and cultural critic Neil Postman was born. He is best known for his works criticizing the increase of the role of technology in every human's life not seeing the dangerous side effects.
On October 4, 1903, American physicist and inventor John Vincent Atanasoff was born. He is best known for being considered as one of the inventors of the electronic digital computer. Even computer scientists most probably haven't heard anything of this computer pioneer. Of course you will have heard about Alan Turing or John von Neumann, which are traditionally references as being the father of the computer. Maybe, when you are European or even German, then you will have heard of Konrad Zuse, who in near total intellectual isolation constructed the first universal computer Z3, which became operational in May 1941. So why is it, we havent heard of John Atanasoff? Although, he came up with the idea of a binary digit universal computer in the late 1930s and constructed his ingenious device little later on, he never secured a patent for his device and lots of the concepts he pioneered were incorporated into the breakthrough ENIAC computer that evolved into the legendary UNIVAC.

. In more recent times, scientist have harnessed the power of the public not only to collect data on a larger scale than perhaps would otherwise be possible, but also to analyse data gathered by professional researchers. Such data analysis projects include Zooniverse’s Galaxy Zoo and Cell Slider projects, whilst WheelMap, Wide Noise and the Opal Tree Health Survey focus on data collection.
Written by PLoS Computational Biology Editor-in-Chief Philip E. Bourne, sometimes with collaborators, the "Ten Simple Rules" provide a quick, concentrated guide for mastering some of the professional challenges research scientists face in their careers. New articles will be added to the Ten Simple Rules Collections as they are published.
The European Science Foundation promotes high quality science at a European level. It acts as a catalyst for the development of science by bringing together leading scientists and funding agencies to debate, plan and implement pan-European initiatives.
Mit der Plattform handbuch.io, die auf der Software MediaWiki basiert, wollen wir demonstrieren, dass wissenschaftliche Literatur heute vollständig im Web geschrieben, gelesen und verbessert werden kann. Geeignet ist die Plattform für 'traditionelle' Buchprojekte, aber auch für Buchprojekte, die als 'Living Book' konzipiert sind, d. h. dass die Autoren ihre Beiträge jederzeit aktualisieren und so neueste Entwicklungen in ihrer Disziplin berücksichtigen können.
The Smithsonian geared the 60 videos towards junior high schoolers and above, and they are usually a minute in length. The videos answer those questions kids, and sometimes adults wonder like " Does Stress Turn Your Hair Gray?" or "Why Do Songs Get Stuck in My Head?"
“They call it a ‘bi-literate’ brain,” she says. “The problem is that many of us have adapted to reading online just too well. And if you don’t use the deep reading part of your brain, you lose the deep reading part of your brain.”
Vaclav Klaus über seiner Erfahrung Der moderne gerichtliche Aktivismus ist in vieler Hinsicht ein Ausdruck des alten Glaubens, dass die Demokratie durch die Aristokratie gemäßigt werden muss "(James Grant) "Einrichtungen wie NROs, die als Produkte organisierter Interessengruppen hervorgegangen sind und die auf unpolitische Weise Vorteile und Privilegien erstreben, leugnen ganz unverblümt die Liberalisierung der menschlichen Gesellschaft, die während der vergangenen beiden Jahrzehnte stattgefunden hat."
Scientists reject Harper gov't claims vital material is being saved digitally. By Andrew Nikiforuk, 23 Dec 2013, TheTyee.ca "Scientists say the closure of some of the world's finest fishery, ocean and environmental libraries by the Harper government has been so chaotic that irreplaceable collections of intellectual capital built by Canadian taxpayers for future generations has been lost forever."
"Starting in 2003, the scientists began teaming up in public talks in which they lay out their arguments in the form of a conversation. Filmmaker Gus Holwerda picks up this evolution as the pair take their skeptical show on the road, tangling with religious leaders, talk-show hosts and several thousand years of cultural inertia. The result is the feature-length film The Unbelievers, which had its world premiere in Toronto at the Hot Docs festival on Monday night." The Editor: "Christianity is dying, and good riddance, says Richard Dawkins "
GigaOm 22 Aug 2012: "Co-founder and CEO Victor Henning told me that the company’s API, which offers other services access to its trove of millions of scientific documents, has just surpassed 100 million calls each month. A year after launching the service — which provides access to the information stored in around 65 million scientific papers, documents and files in Mendeley’s databases — the site has around 240 apps that employ it, and is now seeing growth rocket. And that growth, he said, comes through the increasing popularity of those apps, not through any new, specific effort on its own part."

14 mars 2013: Les listes de l'Union générale des étudiants de Tunisie ( UGET ) ont remporté la majorité des sièges des conseils scientifiques dans les 165 établissements universitaires.« L'UGET a réalisé un succès historique en nombre de sièges obtenus et en taux de présence dans les établissements universitaires puisqu'on a remporté 295 sièges sur un total de 549 sièges » a déclaré à l'Agence TAP Ezzedine Zaatour, secrétaire général de l'UGET commentant les résultats des élections des conseils scientifiques qui ont eu lieu ces derniers jours. « Notre organisation a obtenu la première place pour ce qui est du nombre de sièges obtenus dans les conseils scientifiques suivie des listes indépendantes.Les listes de l'Union générale Tunisienne des Etudiants ( UGTE ), inféodé au mouvement islamiste Ennahdha au pouvoir, vient en troisième position », a encore expliqué Zaatour.Le représentant de l'UGET a qualifié les élections des conseils scientifiques de »transparentes et démocratiques » saluant la neutralité de l'administration.
"The Only Group That Can Categorize Everything Is Everybody ", Clay Shirky writes. Why group? Anybody can do it. What is the difference between anybody and everybody?
However unlike the Green Revolution 30 years ago, there is virtually no more tillable-land available to grow rice. Future gains must be made solely by improving rice yields, and on top of that, there's an imperative to use fewer harmful chemicals as fertilisers and for pest control.
En artikel av Leonardo Vintiñi, i Epoch Times 12 oktober 2008 om Cleve Backsters experiment med växter och lögndetektorer i början av 1960-talet och prof Ian Baldwins uppföljande forskning . "Forskare runt om i världen fortsätter att komma med bevis för att växter är mycket mer än de primitiva och passiva varelser som vi en gång trodde. En sådan forskare är Ian Baldwin från institutionen för molekylär ekologi på Max Planck-institutet i Tyskland. Baldwin hävdar att växter inte bara kan avge kemiska substanser för att försvara sig själva mot rovinsekter, utan att de också faktiskt kan kommunicera sinsemellan genom en komplex vokabulär av nukleinsyror."
