Computational GRIDs and online laboratories
Many projects addressing the creation of online laboratories have been developed recently. They have a common goal: to enable students and professional learners to get hands-on experience without moving from the places where they are. Nevertheless, the found solutions are often very different among them, and interoperability between different online laboratories systems does not exist. In this paper we present our work around the exploitation of Grid technologies for sharing instrumentation and

Can research on science learning and instruction inform standards for science education?
We contrast the current science education reform effort with the reforms of the 1960s and suggest how the current effort could be enhanced. We identify insights from recent research that we believe can inform the reform process, in particular, to reach all science students and also impart a cohesive view of science. We propose an ldquoalternative modelsrdquo view of scientific explanation and show how this view would contribute to reforms of (1) course goals, (2) social aspects of science learni

The Climate Visualizer: Sense-Making Through Scientific Visualization
This paper describes the design of a learning environment, called the Climate Visualizer, intended to facilitate scientific sense-making in high school classrooms by providing students the ability to craft, inspect, and annotate scientific visualizations. The theoretical background for our design presents a view of learning as acquiring and critiquing cultural practices and stresses the need for students to appropriate the social and material aspects of practice when learning an area. This is fo

Cyclone in the classroom: bringing the atmospheric science community into the high school
There has been much discussion about the failure of traditional science education to prepare students for careers in science (Halloun & Hestenes, 1985; Rutherford & Ahlgren, 1990). Students may become adept at solving textbook problems, but they fail to apply the theories that are learned in school to the actual phenomena that the theories attempt to explain (Tinker, 1992). This is in large part due to the fact that students don't often experience phenomena in the classroom. They spend most of t

Synthesizing instructional technologies and educational culture: exploring cognition and metacogniti
This research was initiated to examine instructional technologies and educational cultures in relation to identified cognitive and metacognitive strategies uses in school tasks. The project involved activities from the social studies curricula that were presented through two new software programs intended to support the development of problem-solving and reasoning strategies - IDEA [Interactive Decision Envisioning Aid, Pea (76)] Notecards (34) - and through instructional approaches bases upon "

Supporting Conceptual Awareness with Pedagogical Agents
This paper describes a series of efforts in building and conceptualizing software agents for distributed collaborative learning. The agents are referred to as pedagogical agents. We have integrated pedagogical agents within two collaborative environments, TeamWave Workplace and Future Learning Environment. The role of agents in these environments differs from past work on software agents in their function as extended awareness mechanisms, focusing on task and concept awareness (conceptual a

Understanding the task: How is agency distributed between tools, students and teachers in technology
In this paper we explore how students’ agency relates to openness and structure within technology-rich, student-centred learning environments. This is done by analysing how students’ understandings of tasks evolve through their activities in relation to the representations in the learning environments. In our interpretation of the sociocultural approach, we emphasise human activity as mediated by artefacts, where the output of the activity has to be understood by including human action and a

Informatics-based Learning Resources for Patients and their Relatives in recovery
In this paper we describe experiences from design of an informatics-based learning resource for patients and relatives. The prototype, REPARERE (learning REsource for PAtients and RElatives during REcovery), aims to support patients and their family recovering from heart surgery in meeting challenges in to daily living post discharge. Using recovery experiences and patient teaching material, REPARERE includes examples of textual information, video-clips, images and illustrations relevant to th

Categorisation in Knowledge building
In this paper we explore how students talk and reason when they were exposed to a set of categories taken from scientific discourse. The scientific categories are built into a web-based discussion forum (Fle) as part of a pedagogical and technological design. The scientific categories are based on the concepts of the progressive inquiry model for knowledge building. Socio-cultural theory with a focus on concepts like categories and prompting is our theoretical framework. In the DoCTA NSS proje

Collaboration and Problem Solving in Distributed Collaborative Learning
Ethnomethodology and Conversation Analysis are utilised as resources for analysing distributed collaborative learning. Thematically we are interested in how a group of students manage their task, how they keep a joint focus, and how technology features in their activity. We present and analyse extracts of data from a group collaborating in a groupware system called TeamWave Workplace. We conclude that in collaborative problem solving the interpretation of the task and the problem solving process

Learning Objects 4: Applications, Implications, & Future Direction
This is the fourth and final book of this series on Learning Objects (LO). Whereas the first three books were essentially concerned with current developments in the field, this book presents a wide-ranging series of discussions of potential and probable developments in the field. Part I encompasses Chapters 1 through Chapter 5. The focus is upon LO within the context of e-learning and online learning. We realize that our authors (like us) often use the terms "e-learning" and "online learning" in

Learning Objects 2: Standards, Metadata, Repositories, and LCMS
This book is the second in a four-volume series. It builds upon the first volume by taking an extended and in-depth look at theorists' and practitioners' efforts to consolidate current knowledge and praxis. This consolidation centers around conceptual and technological issues related to standards, metadata, repositories, and the concept of the LCMS (Learning Content Management System). Part I contains six chapters that focus upon LO concepts vis-à-vis architecture. A discussion of syntax, seman

L'Algebrista: un manipolatore simbolico elementare
Presentazione di un nuovo software didattico per l’introduzione degli allievi all’algebra. L’idea di base è quella di costruire un micromondo nel quale le attività di manipolazione simbolica corrispondano alle attività di deduzione all’interno di una teoria. L’ipotesi didattica vede tale micromondo come possibile mediatore del significato di teoria ed in particolare di dimostrazione.

Calculators, graphs, gestures and the production of meaning
In this paper we report an analysis of a teaching sequence in which Grade 11 students were asked to produce some graphs corresponding to the relationship between time and distance of a cylinder moving up and down an inclined plane. The students were also asked to carry out the experience using a TI 83+ graphic calculator equipped with a sensor, and to discuss and explain the differences between their own graphs and the ones obtained with the calculator.
