Towards educational data mining: Using data mining methods for automated chat analysis to understand
In this paper we investigate the application of data mining methods to provide learners with real-time adaptive feedback on the nature and patterns of their on-line communication while learning collaboratively.We derived two models
for classifying chat messages using data mining techniques and tested these on an actual data set [16]. The reliability of the classification of chat messages is established by comparing the models performance to that of humans. Results indicate that the classificatio

Millions of prisoners suffered the brutal assault on human dignity that was the Gulag. Many Days, Many Lives presents the history of this system through a browseable archive of video, art, artifacts, photographs, and the life stories of former Gulag prisoners. Online exhibitions take visitors on a thematic exploration of Gulag life, including a virtual tour of the reconstructed camp and museum made possible by the Gulag Museum at Perm-36. Teaching resources for introducing the Gulag's history in
Internet Scout Project
The "Earth Observing System (EOS) Aura is a NASA mission to study the Earth's ozone, air quality, and climate" by researching the composition, chemistry, and dynamics of the Earth's atmosphere. Visitors can learn how Aura is investigating three questions: Is the Earth's ozone layer recovering? Is air quality getting worse? How is Earth's climate changing? Researchers can find extensive details about the flight, spacecraft devices and specifications, and the data processing and validation. Visito
Science In Focus: Energy
Interview with Stephen Connors about limited sources of energy and the importance of using renewable sources.,In this segment, several renewable sources of energy are described as well as some of the advantages and disadvantages of each. The sources discussed in this segment are photovoltaics, wind power, biomass, geothermal, hydropower, nuclear power,tidal and wave power are mentioned but not discussed at length. He then makes the point of the necessity of acknowledging significant trade-offs
Earth Exploration Toolbook Chapter: Looking into Earth with GIS
Step-by-step instructions walk users through working with data from a seismic wave model in a freely available GIS (geographic information system) program, ESRI's ArcVoyager SE. Users generate and examine maps and produce graphs to explore variations in seismic wave velocities at depths of 28 and 100 km below Earth's surface. By examining and analyzing GIS-ready data, users visualize density changes and earthquake distributions near a spreading center and two subduction zones. Finally, users wil
Database Management Systems
A more formal approach to Relational Database Management Systems, compared the way they were covered during Web Applications. Database systems are discussed from the physical layer of B-trees and file servers to the abstract layer of relational design. Also includes alternative and generic approaches to database design and database management system including relational, object-relational, and object-oriented systems, SQL standards, algebraic query languages, integrity constraints, triggers, fun
Statistics
This course introduces students to the basic concepts, logic, and issues involved in statistical reasoning. Major topics include exploratory data analysis, an introduction to research methods, probability, and statistical inference. The objectives of this course are to give students confidence in manipulating and drawing conclusions from data and provide them with a critical framework for evaluating study designs and results. An important feature of the course is the use of an intelligent tutori
Patrons d'exercices pour Aplusix Une étape du développement de l'EIAH occasion d'un travail entre
Au cours du développement de l'EIAH APLUSIX, il y a eu de nombreuses occasions d'un travail partagé entre informaticiens et didacticiens. Quelques-unes sont décrites succinctement. Lors de la mise en place de patrons d'exercices et d'une carte de tests, une coopération plus approfondie a eu lieu, en respectant les disciplines de chacun. Cette mise en place de patrons d'exercices est décrite plus longuement.,Preprint
Physics
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,
System Solver
Highlight how symbolic operations on a system of linear equations do (or do not) change the graphic or tabular representations of the system.
Note that the System Solver is a tool intended to illustrate the rationale behind the symbolic operations used to solve systems of linear equations, and not a way to learn what procedures to follow.
Fostering collaborative knowledge construction with visualization tools
This study investigates to what extent collaborative knowledge construction can be fostered by providing students with visualization tools as structural support.
Thirty-two students of Educational Psychology took part in the study. The students were subdivided into dyads and asked to solve a case problem of their learning domain under one of two conditions: 1) with content-specific visualization 2) with content-unspecific visualization. Results show that by being provided with a content-specific
Private Universe Project in Mathematics: Workshop 4: Thinking Like a Mathematician
What does a mathematician do? What does it mean to think like a mathematician? This program parallels what a mathematician does in real life with the creative thinking of students.,Rominas Proof - Responding to a problem posed by one of the students, Romina, a 10th-grader, invents a proof solution and shares it with the others.

Autoevaluation in 8086 assembly language programming
Autoevaluation (self assessment) is more and more developed for teaching at university. We present our contribution to this pedagogical resource. Our exercises are intended for students in second year at the University of Paris 6 for the module "Computer Architecture". These numerous exercises complete the classical courses and allow students to check their know-how. We have experimented with success our set of exercises for the past 2 years with numerous students in UTES1. Uteval software has b

It may be that the struggle between Society and the State is inevitable; it may be i
Making sens: science education networks of sensors
A small group of leaders from research, industry, and education convened in a one-day workshop at Stanford's Center for Innovations in Learning (SCIL) to brainstorm on the use of data probes, sensors, and communication technologies in the development of innovative science education curricula. This report documents the results of a morning brainstorm and afternoon group exercises developing educational scenarios for which sensor networks would be powerful in enhancing learning content and promoti

Envisioning Cyberspace: The Design of On-Line Communities
The development of the World Wide Web into an active, visual social environment poses unique opportunities for the design professions. Multi-user Domains, social meeting places in cyberspace, are mostly text-based virtual realities which use spatial references to set the stage for social interaction. Over the past year design students at the New Jersey Institute of Technology School of Architecture have investigated several text-based domains. In the course of their work, they envisioned and gra
