A Model for Interoperability in Computer Supported Collaborative Learning
Computer Supported Collaborative Learning activities involve combination of complex software tools that often need to interoperate in a wider context of learning. This paper proposes a data model that accommodates requirements of typical collaborative learning situations and facilitates interoperability of tools and interchange of products of collaboration and evaluation data. The model has been tested against various typical tools used for both synchronous and asynchronous collaboration of grou
Cognitive factors related to user involvement with computers and their effects upon learning from an
Cognitive theories proposed to explain the high motivation to use, and deep involvement with computers, often found in schoolchildren suggest three main factors. They are: desire in the user to control the computer; the user responds to a perceived challenge from the computer; and the user wishes to explore the complexity of the computer software. The paper describes an experiment using a specifically developed piece of software to investigate these factors and to assess their effects on involve
APLUSIX, A learning environment for algebra, actual use and benefits
After a presentation of the APLUSIX system, a learning environment for formal algebra, we describe the use of this system in a French class of grade 10, in particular a sequence devoted to factorisations and equations, and an analysis of the students' work during this sequence. This study exhibits the influence of the tools provided by the software on the construction of competences in algebra. We also report the opinion of a teacher who used the APLUSIX system during one year with this class.
Educational Tool for Nanophysics Using Multisensory Rendering
The presentation and the evaluation of an educational tool used to teach physical phenomena that take place at a nanometer scale are the central objectives of the work presented in this paper. Through concepts and tools, the real phenomena are connected to the virtual world, which furnish sensorial representations (haptic, visual, auditory) for the student who is experimenting. A computer representation of the nanoscene at the atomic level offers a multisensory tangible artifact of nanoworld ina
Progression in Multiple Representations: Supporting students' learning with multiple representations
Relating multiple representations and translating between them is important to acquire deeper knowledge about a domain. To relate representations, learners have to mentally search for similarities and differences. To translate between representations, learners need to interpret the effects that changes in one representation have on corresponding representations. The question is how presenting representations may improve or hinder the processes of relation and translation. In this study we examin
Collage, a Collaborative Learning Design Editor Based on Patterns Special Issue on Learning Design
This paper introduces Collage, a high-level IMS-LD compliant authoring tool that is specialized for CSCL (Computer-Supported Collaborative Learning). Nowadays CSCL is a key trend in e-learning since it highlights the importance of social interactions as an essential element of learning. CSCL is an interdisciplinary domain, which demands participatory design techniques that allow teachers to get directly involved in design activities. Developing CSCL designs using LD is a difficult task for teach

Is Lipid-Lowering Therapy Underused by African Americans at High Risk of Coronary Heart Disease With
Objectives. We examined whether racial differences exist in cholesterol monitoring, use of lipid-lowering agents, and achievement of guideline-recommended lowdensity lipoprotein (LDL) levels for secondary prevention of coronary heart disease. Methods. We reviewed charts for 1045 African American and White patients with coronary heart disease at 5 Veterans Affairs (VA) hospitals. Results. Lipid levels were obtained in 67.0% of patients. Whites and African Americans had similar screening rates an

RVC 48 - Anal furunculosis in dogs
Anal furunculosis is a particularly unpleasant disease of the rear end that particularly affects German Shepherd dogs. Here Dr Brian Catchpole and Prof Susan Gregory outline the traditional way the disease is identified and treated, their recent findings on how it may be caused, and how these findings inform current best treatment practices.

Conflict resolution: Raising an issue
The way we raise an issue has a significant effect on the entire problem-solving process. By raising an issue in a constructive way, we set the stage early for resolving the conflict productively. The purpose of this unit is to give participants an opportunity to practice and explore this type of problem solving.
