Designing for cross-cultural web-based knowledge building
This paper describes the iterative design of a web-based collaborative workspace used in educational practice, called WebReports. The systemâs unique feature is that it allows participants to discuss mathematical and scientific concepts using programmed animated and interactive models of their ideas. Rather than focusing on the specific features of the collaboration tool, we analyze it as part of a constructionist activity system. We describe the context in which the system was developed an
Role-based integration of evaluation and regulation in collaborative learning environments
Interaction analysis has become a basic function in the field of collaborative learning, as a means for supporting both self-regulation for the students and formative evaluation for the teachers. In spite of the fact that these processes rely on the same basic functionalities, there is a lack of proposals or systems that integrate them. This paper presents a research proposal that argues for a role-based approach for the integration of these functions. The experience of awareness systems in CSCW
Socio-cultural Perspectives on Object-oriented Learning
One of the central objectives of project COOL is to explore critical aspects associated with learning (and teaching) object-oriented concepts. This objective will be pursued by bringing forth the heritage of Kristen Nygaard and the Norwegian approach to object-orientation. The project will develop learning material based on this work and intends to make the material available to the object-oriented community in the form of reusable learning objects. This paper explores how social-cultural theori

Trails of Digital and Non-Digital LOs
This document investigates scenarios where learners navigate (follow trails) through environments containing digital and non-digital learning objects, considers some user requirements of systems designed to support the use of trails and presents a possible classification of different types of trail to form an ontology of trails. Separate sections include investigations of trails in different pedagogical approaches, trails in mobile learning scenarios, trails in computer conferencing and the prov
Between arithmetic and algebra : a space for the spreadsheet ? Contribution to an instrumental appro
In this research work, we have a didactical look on the integration of a computer tool into mathematics teaching: the spreadsheet. We have related research about spreadsheet to an instrumental approach perceived as essential to analyze the questions of technological integration. This approach allowed us to extend to this technology the theoretical framework of instrumentation. These theoretical elements are being used in the analysis of the professional resources and the teaching practices, in o
Earth Science Today
This laboratory exercise, designed for an introductory Earth Science course, examines stratigraphy and plate tectonics while considering predictions as a way to test theories. The laboratory focuses on the reconstruction of Pangaea and evidence for geologic events in rock layers. Users can also link to the course homepage and other activities related to Earth Science Today.
Confronting Health Inequity: The Global Dimension
Since the days of Hippocrates, health inequities and the role of social and environmental factors in the determination of marked differences in health status have been well recognized. For some time now, the driving force behind public health has been understanding and intervening in the underlying causes of health inequity. The publication of the Black Report1 in the United Kingdom in 1980 brought a more focused approach to this discourse by identifying specific factors, such as social class, g
Racial/Ethnic Disparities in Preschool Immunizations: United States, 1996–2001
Objectives. We examined current racial/ethnic differences in immunization coverage rates among US preschool children. Methods. Using National Immunization Survey data from 1996 through 2001, we compared vaccination coverage rates between non-Hispanic White, non-Hispanic Black, Hispanic, and Asian preschool children. Results. During the 6-year study period, the immunization coverage gap between White and Black children widened by an average of 1.1% each year, and the gap between White and Hispa
Developing the Theory: Continental Drift
This document outlines the development of the theory of continental drift and how many lines of evidence collected over several decades by various researchers were brought together to explain how the seafloor spreads and the continents move about. Links to additional information are included.

Lecture 28 - 11/29/2010
HEALth Case Studies
This program was designed for dental hygiene and dentistry students to help them learn about evidence-based dentistry and its role in providing quality dental care. This program uses patient-based case studies combined with interactive tools and activities to help students become effective consumers of oral health research data. They learn to locate, evaluate, and use the outcomes of research studies to improve patient assessment, diagnosis, clinical decision making, and treatment planning, as w
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.

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
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.
A Gallery of Institutional Projects
