Ratios for all occasions
A central theme in the middle school mathematics curriculum, proportional reasoning is based on making sense of ratios in a variety of contexts. The resources chosen for this unit provide practice in solving problems, often informally, in the format of ga

Positioning and Navigation: Services for open educational practices
To choose suitable resources for personal competence development in the vast amount of open educational resources is a challenging task for a learner. Starting with a needs analysis of lifelong learners and learning designers we introduce two wayfinding services that are currently researched and developed in the framework of the Integrated Project TENCompetence. Then we discuss the role of these services to support learners in finding and selecting open educational resources and finally we give
Real Remote Mass Spring Laboratory Experiments across InternetInherent Part of Integrated E-Learni
The paper presents the application of Integrated e- Learning, presented in general terms at this conference , exemplified on one of the most important parts of Physics - the thematic block Oscillations. The goal of the course of Physics in the chapter of Oscillations is to show the oscillatory movement as a basis of nearly all natural phenomena. The unifying model for all real world systems then may be the mass-spring system constituting the mechanical oscillator. The three constituting c
Supporting a Learner Community with Software Agents
This paper describes a multi- agent approach that aims at supporting learners involved in a collective activity. We consider pedagogical situations where students have to explicitly define the articulation of their collective work and then achieve the different tasks they have defined. Our objective is to support these students by taking some of these tasks in charge whilst making them work out such organisation features. For this purpose, we propose to consider that the group of students forms
Monarchs, People, and History, Summer 2008
The origins and reasons for monarchy as an institution and social force in the Western world. Specific royal personages are studied with attention to how they attained or lost effectiveness as leaders; their goals for themselves and their people are stressed. These themes are explored through primary source readings. Architectural, artistic, and musical evidence are introduced in slide and tape sessions.
Liberty, Equality, Fraternity: Exploring the French Revolution
This accessible and lively introduction to the French Revolution presents an extraordinary archive of some of the most important documentary evidence from the Revolution, including 338 texts, 245 images, and a number of maps and songs
Authoring Intelligent Tutoring Systems:
An analysis of the state of the art
This paper consists of an in-depth summary and analysis of the research and development state of the art for intelligent tutoring system (ITS) authoring systems. A seven-part categorization of two dozen authoring systems is given, followed by a characterization of the authoring tools and the types of ITSs that are built for each category. An overview of the knowledge acquisition and authoring techniques used in these systems is given. A characterization of the design tradeoffs involved in buildi
Four Easy Pieces: Development Systems for Knowledge-Based Generative Instruction
The Experimental Advanced Design Advisor (XAIDA) is a system for the development of computer-based maintenance training. XAIDA acquires knowledge of a device from a subject matter expert and applies common maintenance-training procedures to generate interactive training from the description. XAIDA provides maintenance training in four areas: the physical characteristics of a device, its theory of operation, operating and maintenance procedures, and troubleshooting. XAIDA relies on an instruction
Cancer Statistics, 2003
This Web site contains a recent report on cancer statistics prepared by the American Cancer Society (ACS) that uses incidence data from the National Cancer Institute and mortality data from the National Center for Health Statistics. The report offers "an up-to-date perspective on the occurrence of cancer" in the United States, including cancer frequency, incidence, mortality, and survival statistics for 2003. The Web site provides links to similar articles, the PubMed citation for the report and
Doing Science and Technology: The Process of Scientific Inquiry
This site helps students understand the basics of scientific inquiry. Lessons progress from what students already know about scientific inquiry, or think they know, toward a more complete and accurate perspective. Activities include distinguishing questions that can be tested by a scientific investigation from those that cannot and participating in a computer-based scientific investigation as members of a fictitious community health department.
Synchronous computer mediated collaborative activities among collocated students: Conditions that ma
Synchronous collaborative activities are usually studied in conditions where teachers and students are physically separated. Is there any possibility to apply these activities when all participants are collocated? Does this collocated collaboration setting seems meaningful and for what reasons? Is the quality of learning and teaching process satisfactory high? Under what conditions? The present research explores the previous questions. More specifically, it explores synchronous computer mediated
Essential Science for Teachers: Physical Science
In-depth interviews with children that uncover their ideas about the topic at hand.,This segment shows how the interviewer uses phenomena to develop the idea that the salt in a solution has not disappeared and it can be recovered. He presents the beaker of salt with water evaporated and the segment shows how he helps the student reconcile his ideas about the salt going away and the weight being less with the scientific explanation.
Essential Science for Teachers: Physical Science
In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer is using the phenomenon of salt dissolving in water to build upon the student's previous ideas about mixing substances together. This time the student sees one of the substances as "disappearing." Even though he says the mixture will still taste salty, which is evidence that there is salt in the water, he shows that he holds on to a belief that the salt has disappeared and is gone.
Rôle des ontologies en ingénierie des EIAH : cas dun système dassistance au design pédagogiq

Une typologie des fonctions des modèles formels : l'exemple de la biologie
Une typologie des fonctions des modèles est construite à partir dun cadre théorique (Nifle) permettant de définir le rapport entre modèle et expérience. Il est admis quil existe un lien entre la manière dont on modélise en tant quexpert ou chercheur et la manière dont on apprend à modéliser en tant quétudiant, et que ce lien repose sur le rapport expérience/modèle. La typologie est construite pour le cas particulier des modèles formels (utilisant un formalisme mathématiqu
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer builds upon the student's idea that rock can break down into sand by asking if the student thinks the sand can ever come together to form rock again. This video is helpful in assisting teachers to understand that a student may have the idea that rock breaks down into sand but doesn't know that the sand can reform into rock, which is necessary to understanding sedimentary rock formation.
Collaborate and Create Inservice
The Collaborate and Create learning project is an online resource created to assist in the in-service of educators seeking to integrate technology into their classroom curriculum. This resource will assist in the development of learning groups organized around real problems of practice that provide access to outside resources and expertise.
