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
Exploring the mathematics of motion through construction and collaboration.
In this paper we give a detailed account of the design principles and construction of activities designed for learning about the relationships between position, velocity and acceleration, and corresponding kinematics graphs. Our approach is model-based, that is, it focuses attention on the idea that students constructed their own models – in the form of programs – to formalise and thus extend their existing knowledge. In these activities, students controlled the movement of objects in a prog
The role of roles in the analysis of interactions in collaborative environments
Analysis of interactions has become a basic function in the field of collaborative learning, as a means for supporting both students' self-regulation as well as formative evaluation processes. However, we observe a lack of methods and tools for the analysis of interactions in CSCL that considerer the different roles implied in collaboration management processes, both from the point of view of the actors that take part in a typical CSCL scenario: teachers, students or the system
The role of interactive visualizations in the development of concepts of logic.
The main objective of the experiments described in this paper is to examine whether instructional variables often used in learning empirical sciences can also be used to facilitate the development of knowledge and skills in the formal sciences, particularly in learning logic. In learning empirical sciences, many positive effects have been reported which can be accounted for by the use of visualisation techniques, multiple representations and possibilities for the learners to interact with repres
Integrating Traditions. Communication Revisited
"Technology-enhanced Learning" gains special importance if we look closely at the concept of technology on the one hand, and learning activity placed into the framework of communications technology on the other. The importance of communications technology has been emphasized by many Hungarian scholars in the first third of the 20th century and due to historian István Hajnal technology has become deeply integrated into the framework of human activities. I'd like to delineate the main sources of
La evaluación social e individual en la era de la educación a distancia en la globalización
En la globalización tan ampliamente fomentada, especialmente por la educación a distancia, debemos cuestionarnos sobre los valores que vivimos en nuestras culturas locales. La evaluación que instauramos dentro de nuestros cursos puede también convertirse en otro mecanismo de homogenización. Para contrarrestar estas desventajas y poder construir juntos sociedades distintas pero solidarias, propongo un análisis de la evaluación como vehículo ideológico de perpetuación de la distribución
Constructing structure in number sequences
This paper reports on a design experiment in the domain of number sequences conducted in the course of the WebLabs project1. In this study, we designed and tested a set of activities in which 13-14 year old students use the ToonTalk programming environment to construct models of sequences and series, and then use the WebReports web-based collaboration system to share these models and their observations about them. We utilise a design pattern (programming method) called "Streams" which enables st
Thinking in Progress
This article tells the story of 11-14 year- o l d students using a rather new and relatively untested programming system to represent and discuss some deep mathematical ideas. There is one caveat: we have chosen the episodes to indicate the possibilities that can emerge when children are given new ways to talk and think about mathematics. We cannot lay claim to any generality: we would invite the reader to look where we are pointing, not at our fingers!
Teaching and learning with ICT: new technology, new pedagogy
This paper has two broad aims: first, to provide a brief introduction to the InterActive Education Project from which the papers in this special edition derive; and second, to draw out some of the overarching themes and threads that have emerged from the set of articles presented. The evidence suggests that a number of tensions surface when subject teachers engage with information communication technology (ICT) in their classrooms, for instance, the tension between teaching about and teach
Learning Imaging Techniques!
During this activity, students will be introduced to the concepts of the challenge. They will generate ideas for solving the grand challenge first independently, then in small groups. Finally, as a class, students will compile their ideas with a visual as a learning supplement.

Topics in Pre-Modern Chinese History
A goal of this book and the course as a whole is to encourage broad, integrative thinking about history and human affairs. Readers are encouraged to compare Chinese history with the histories of other parts of the world and with contemporary problems and issues. Readers are also encouraged to think about the process of history making (i.e., writing) itself.
Racial Differences in 30-Day Mortality for Pulmonary Embolism
Objectives. Previous studies reported a higher incidence of in-hospital mortality for Black patients who had pulmonary embolism than for White patients. We used a large statewide database to compare 30-day mortality (defined as death within 30 days from the date of latest hospital admission) for Black and White patients who were hospitalized because of pulmonary embolism. Methods. The study cohort consisted of 15531 discharged patients who had been treated for pulmonary embolism at 186 Pennsylv
Challenges in Changing the Face of a City
This lesson is designed to explore the complex challenges Oakland's Mayor Jerry Brown faces as he attempts to bring change to the city of Oakland. Key issues include housing, poverty, gentrification, politics and business development.
An Issue of Loyalty: Exploring the Treatment of Japanese Americans During World War II (1941-1945)
This lesson is designed to explore the issue of loyalty and disloyalty with regards to Japanese Americans in the internment camps during WWII. Students will examine these abstract ideas as they relate to their lives.
A lesson in which students examine five examples of roadside architecture built in the 1920s and 30s to catch the eye of passing motorists. They include the Teapot Dome Service Station, the Big Duck poultry store, and the Benewah Milk Bottle.
Contemporary life in Vietnam
Photographs and text describe contemporary life in Vietnam and the impact of economic and social reforms since the 1980s.
International Relations in a Post-Hegemonic Age
The academic study of International Relations has, since since its emergence after World War I, sought to combine the development of theoretical frameworks with an engagement, of greater or lesser immediacy, with the changing course of international events. Empire, World War, Cold War and post-1991 US hegemony have all been objects of its concern. Today, oscillating at times uneasily between the enticements of abstraction, and the rush of actuality, the discipline faces a major opportunity, to p
Art in Wichita: instruction, collection and innovation
Art instruction, renowned collections and contemporary innovation represent the various offerings of Wichita’s primary visual art centers: the Wichita Center for the Arts, the Wichita Art Museum, and the Edwin A. Ulrich Museum of Art. Through their separate programs and objectives, these three institutions contribute to the city’s cultural vitality and make it more than just another dot on the map. Without the foresight of a number of her citizens, Wichita’s cultural climate would have rem
