"Oh God, For One More Breath": Early 20th century Tennessee Coal Miners' Last Words
Coal mining and railroad work were the two most dangerous trades in the United States in the early 20th century. Coal miners frequently died in spectacular explosions and cave-ins that could kill dozens or even hundreds at a time. Although most testimony about coal mining disasters came from survivors and observers, the men who suffocated to death in the Fraterville, Tennessee mines in May 1902 left behind their own grim account. Trapped in the mine after an explosion and with their air rapidly
No Way Out: Two New York City Firemen Testify about the 1911 Triangle Shirtwaist Fire
One of the greatest industrial tragedies in U.S. history occurred on March 26, 1911, when 146 workers, mostly young immigrant women, died in a fire at the Triangle Shirtwaist company in New York City. In this brief excerpt from their testimony before the Factory Investigation Commission, New York City Fire Chief Edward F. Croker and Fire Marshall William Beers commented on the safety lapses--the locking of an exit door, the inadequate fire escapes, and the overcrowded factory floor--that led to

2.3 Operant conditioning According to behaviourism, all behaviour is learned and maintained by its consequences. B. F. Skinner (1905–1990) devised apparatus and methods for studying these effects. Figure 3 shows a ‘Skinner Box’ designed for use with a rat. The early behaviourists often examined animal learning and then extrapolated it to human learning. This was because they proposed that the fundamental principles of learning underpin
David Driskell: African American Artist
This video takes place in Maine and this video is centered around this place. Interviews with the artist includes why he paints there and the influence of others on his prints and paintings. A good video to show in art classes and also to emphasis his importance as an art collector and scholar. The video is 2:40 in duration.
Icebreakers: Cow, Alien, Tiger
In this fun improve game students get into a circle and decide to be either cows, aliens, or tigers. The goal is to get everyone to be the samething. (1:24)

Calcul en précision arbitraire
Dans cet exposé Luc Bougé propose une séquence pédagogique autour du calcul avec des très grands nombres qui ne peuvent être codés avec les nombres entiers ou les nombres flottants usuels des machines. Le nombre est alors stocké dans un tableau et devient un objet numérique dont il faut soigneusement définir les opérations, et les méthodes permettant de le manipuler. C'est l'occasion de proposer un travail exemplaire de bonne programmation avec les concepts les mieux adaptés.
L'imagerie satellitaire : une aide à l'enseignement de l'informatique (video)
Dans cet exposé, Henri Maitre montre comment et de quelle façon concrète les images satellitaires de Google peuvent devenir des objets numériques à forte plus-value pédagogique et comment les utiliser pour des séquences pédagogiques. La notion d'image (pixelique) et de carte (symbolique) font l'objet d'une étude comparative et les grandes méthodes de traitement d'images permettant d'extraire des informations symboliques des images aériennes sont décrites, y compris au niveau des
"City of Louisville" at Howard's Shipyard
The boat was built at the Howard Shipyards in 1894. The ship was 301 feet x 42.7 feet x 7 feet.
"City of Louisville" near Madison, Indiana
The ship was built in 1894, in Jeffersonville, Indiana by the Howard Company. It was 301 feet long and 42.7 feet wide x 7 feet deep. It was built for the Louisville-Cincinnati trade and had 72 staterooms. In April, 1894, she completed a record run from Louisville to Cincinnati of 9 hours and 42 minutes. She was lost in ice in Cincinnati in January, 1918.

11 Feb 2011: Scientia Conference on Research and Innovation in Undergraduate Natural Science and Eng
A conference on Research and Innovation in Undergraduate Science and Engineering Education will be hosted by Scientia, an interdisciplinary faculty institute, on the campus of Rice University, a leading research university with a distinctive commitment to undergraduate education. The goals of the conference are to promote a diverse community focused on learning and to cultivate exceptional teaching. The conference will focus on new developments in pedagogy for first and second year undergradua
2.7 Summary Behaviourism proposes that all behaviour is learned and maintained by its consequences. It does not theorise about ‘mental events’. Classical conditioning describes how reflex behaviours can become associated with neutral stimuli in the environment. Operant conditioning describes how the incidence of freely occurring behaviours can be increased or reduced as a result of the incidence of pleasant and unpleasant cons
2.5 Application: applied behavioural analysis Applied behavioural analysis (ABA) is a method of teaching that involves breaking tasks into small, discrete ‘teachable’ steps. At each step appropriate behaviours are reinforced. ABA selects developmentally appropriate behaviours as teaching targets. These can range from maintaining eye contact to complex responses such as social interaction. The child is given enough support to ensure success, which is then positively reinforced by consequences that are reinforcing for that child.
