Computer Algebra Based Assessment of Mathematics Online
In this paper, we investigate computer algebra based assessment of mathematics online, with a focus on undergraduate students. Introducing a computer algebra system to assist in marking allows a paradigm shift from teacher-provided answers to student-provided answers. The Computer Algebra Based Learning and Evaluation (CABLE) system is presented as an open source infrastructure for mathematical learning objects. Features of the CABLE system, including the modular design, database structure, lear

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

Semantic Annotation for Learning Material
This paper aims at providing the specification for semantic annotation tools for e-learning. From the specific requirements of annotating learning material, we categorize and evaluate the existing annotation tools, mainly general purpose ones. We illustrate two research prototypes of annotation tools we developed, and evaluate to what extend the specific requirements of annotating learning material are reached by these research prototypes.

Geospatially aware social software and Africa
We present a proposal for the development and implementation of a group of tools that will support the collection and sharing of georeferenced information. Locations such as rural Africa suffer from a technical problem hampering their participation in the global information community: infrastructures and terminals for Internet access are non-existent or of poor quality. We believe that cell-phone software can be leveraged as a way to bridge this. One important contribution that local communities

Enforcing Cooperative Storytelling: First Studies
In this paper, we describe the first prototype of a system called StoryTable, aimed at supporting a group of children in the activity of storytelling. The system is based on a special multi-user touchable device (the MERL DiamondTouch) and it was designed with the purpose of enforcing collaboration between children. The paper discusses how the main design choices were influenced by the paradigm of cooperative learning and presents two observational studies to assess the effects of the different

Socio-cognitive functions of space in collaborative settings : a literature review about Space, Cogn
This document reports on a brief literature review about social and cognitive functions of spatial features used when collaborating in both physical and virtual settings. Those concepts come from various fields like social, cognitive as well as environmental psychology or CSCW (Computer Supported Collaborative Work). I briefly summarize the social and cognitive affordances of spatial features like distance, proxemics, co-presence, visibility or activity in the context of physical and virtual spa

Grounding is not shared understanding : distinguishing grounding at an utterance and knowledge leve
This paper argues that for the study and facilitation of collaborative learning, existing theories of grounding such as that of Clark and Shaefer [5] cannot be applied without adjustments. When comparing collaborative learning and conversation, four dimensions can be identified where grounding at a knowledge level differs from the grounding at an utterance level. Firstly, the indirect access and the existence of a range of manifest meanings, poses the need for a notion of ‘groundedness'. Second

Collaborative Ontological Engineering of Instructional Design Knowledge for an ITS Authoring Environ
Intelligence in an ITS authoring system could rely on content-based engineering of instructional design (ID) knowledge, i.e. based on principles such as conceptualization, standardization and theory -awareness. An ontology - based architecture with appropriate ontologies has been proposed for a theoryaware ITS authoring system. Ontological engineering (OE) as a collaborative process jointly conducted by an OE expert and an ID expert is presented as a step on a roadmap towards a theory-aware ITS

Design of adaptive feedback in a web educational system
This paper presents our interdisciplinary approach for the design of a technology-based learning environment for orthopaedic surgery. We present how we designed a part of this environment. This part is in relation to the web environment. The key idea is to produce an intelligent feedback in relation to the learner's activity. The didactical analysis of teaching and learning in the workplace gives a framework to build the computational representation of knowledge. This analysis is shown within th

Physics
This book, designed for a two-semester general physics course for science and engineering students, presents a logical and unified approach emphasizing the conservation laws, the concepts of fields and waves, and the atomic view of matter. The special theory of relativity, in its more basic aspects, is used throughout the text as one of the guiding principles that must be met by any physical theory

Size and Scale
Another good lesson plan from DiscoverySchool.com, the Size and Scale Web site gives teachers a well conceived and thorough activity on the physics of size and scale. Objectives of the lesson include: understanding the relative sizes of bodies in our solar system and the problem of making a scale model of the entire solar system (because the distances in space are so great that even a very small scale model would be too large to be practical).

Middle School Portal: Math and Science Pathways (MSP2)
This resource discusses how scientists and engineers study biological systems to develop artificial systems, in this case artificial olfaction. The sense of smell is extremely complex, and scientists working on artificial olfaction have had to study this biological system extensively to extract some basic principles upon which to build their devices. Disciplines of emphasis will involve biology, chemistry, electronics, and teamwork. Copyright 2005 International Technology Education Association

Perceived Versus Actual Risk for Hypertension and Diabetes in the African American Community
Hypertension and diabetes mellitus are leading health concerns in the United States. Despite a disproportionate burden of both conditions among African Americans, it is estimated that 44% of diabetes cases and one quarter of hypertension cases within this population are undiagnosed. Lack of awareness of the risk of these conditions may hinder preventive efforts and the adoption of positive lifestyle changes. Based on the findings from a pilot study to develop and standardize uniform screening fo
