Herschel Infrared Experiment
Students perform a version of the 1800 experiment in which a form of radiation other than visible light was discovered by the famous astronomer Sir Frederick William Herschel.
In molecular physics it is recognized that there is a coupling of rotational and vibrational energy-levels. In molecular physics rotational-vibrational coupling is also called rovibronic coupling and Coriolis coupling. The physics of actual diatomic molecules is more complicated than the example in this animation, but because of its simplicity the animation is useful for illustrating the basic principles.

The current online Andes Physics course is intended to be used with most physics textbooks. It supplements the textbook by providing problems for students to solve with the aid of Andes, an intelligent tutoring system developed at the University of Pittsburgh and the United States Naval Academy with funding from the Cognitive Science program of the Office of Naval Research. Students solve typical textbook problems just as they would with pencil and paper, by entering vectors, coordinate systems,
How Computers Work
Includes the basics of digital logical design, computer organization and architecture including assembly language, processor design, memory hierarchies and pipelining. Students examine the detailed construction of a very simple computer. Problem sets use Beta-Sim, a RISC simulator written by Mike Wessler. A higher level view of a modern RISC architecture is studied, using the Patterson and Hennessey introductory text, from both the programmer's point of view and the hardware designer's point of
Physics to Go
Physics to Go is a collection of websites where you can learn physics on your own, through games, webcasts, and online exhibits and activities. Also included are physics on the road programs, which bring demonstration shows, and in some cases hands-on activities, to you, the audience. To find the resources you want, you can browse the collection and search our database by content topic, resource type, and grade level. We encourage your involvement in Physics To Go. Once you have registered and
Fantastic Fraction Falcons
Explore the fun skills of manipulating fractions.
In this class, students learn about physics principles by examining the physics responsible for producing music with electronic stringed instruments, while building, testing, and playing their own electric guitar. Students will design their own Guitar bodies, construct their own pick-ups, assemble their own guitars, tune them using a chromatic tuner, and use them to play a simple song. While the instructions here give enough detail that an independent learner could construct their own guitar, pl
Relevant material from MIT's introductory courses to support students as they study and educators as they teach the AP Physics curriculum.
La construction de protocole de travaux pratiques
de chimie à laide dun logiciel: quels apport
Larticle présente une étude effectuée avec des élèves de terminale S, à partir de lutilisation du logiciel Educ@ffix.net qui a pour objet lacquisition de connaissances procédurales et déclaratives par la réalisation dun protocole expérimental en chimie. La situation-problème proposée consiste à déterminer la concentration du colo- rant E124 dans un sirop de grenadine. Dans un premier temps, la situation pédagogique modélisée dans lenvironnement informatique est décri
Participating Virtually to a Scientific Conference: A Collaborative E-Learning Scenario for Authenti
This paper presents a collaborative e-learning scenario inspired by socio-constructivist and situated learning theories which encourage authentic learning. Developed for a graduate distance education course, this scenario requires students to participate virtually in an asynchronous scientific conference. This paper presents the learning scenario, the technological environment developed to implement this scenario, as well as the results of a preliminary investigation which examines students p
Internal and external collaboration scripts in web-based science learning at schools
Collaboration scripts can help learners to engage in argumentation and knowledge acquisition. However, they might have differential effects for learners holding differently structured knowledge (internal scripts) on argumentation. We investigated how external scripts interact with learners internal scripts concerning collaborative argumentation. 98 students from two secondary schools participated. Two versions of an external collaboration script (high vs. low structured) supporting argumentati
Epistemic cooperation scripts in online learning environments: Fostering learning by reducing uncert
Using online learning environments in higher education offers innovative possibilities to support collaborative learning. However, online learning creates new kinds of problems for participants who have not previously worked with each other. One of these problems is uncertainty which occurs when participants do not know each other. According to the uncertainty reduction theory, low uncertainty level increases the amount of discourse and decreases the amount of information seeking. Therefore, unc
Lutilisation dun arbre des tâches pour concevoir et analyser des situations dapprentissage :
Afin de prendre en compte les difficultés que les élèves ont pour donner du sens aux activités expérimentales, ce qui leur fait perdre de vue lobjectif initial du T.P. et les connaissances visées, nous proposons de leur faire concevoir le protocole des expériences. À travers trois exemples de situations de T.P. mises au point et expérimentées dans des classes de Terminale S, nous montrons comment la structuration du protocole expérimental dans un arbre de tâche, permet d'analyser e
Calculators, graphs, gestures and the production of meaning
In this paper we report an analysis of a teaching sequence in which Grade 11 students were asked to produce some graphs corresponding to the relationship between time and distance of a cylinder moving up and down an inclined plane. The students were also asked to carry out the experience using a TI 83+ graphic calculator equipped with a sensor, and to discuss and explain the differences between their own graphs and the ones obtained with the calculator. We analyze the students' processes of mea
An environment helping teachers to track students' competencies
Our research concerns teaching assistant systems by treating the question of reuse and exploitation of learners’ profiles by the teacher. We propose also that other actors of the learning situation, learners and institutions, benefit from the exploitation of these profiles. In PERLEA project, we want from one hand to model the students’ tracking process, and on the other hand to propose an environment giving software tools to help actors to reuse and exploit profiles of all disciplines, what
"Everything Was Lively": David Hickman Describes the Prosperity Late Nineteenth-Century Railroads Br
The availability of rail connections often determined whether a western community would survive or die. The rails fostered prosperity by bringing both goods and people. This trade, and the local service industries that sprouted up to capitalize on the movement of people and goods, drove many local economies. Here, David Hickman talked about the boom years that followed the arrival of the railroad in the Latah County, Idaho town of Genesee in the 1880s.
"He'll Come Home in a Box": The Spanish Influenza of 1918 Comes to Montana
In 1918 and 1919, the Spanish influenza killed 550,000 people in the United States and 20 to 40 million worldwide. In a 1982 interview with Laurie Mercier, Loretta Jarussi of Bearcreek, Montana, described how people would pass through that tiny town seemingly healthy, only to be reported dead two days later. Her father went undiagnosed for many weeks and had plans to go to a nearby hot springs to rest. She believed that her father's death was averted only because the son of the local doctor was
