Researching classroom interactions: A methodology for teachers and researchers
Teaching and learning in schools is a complex social process which involves both the teacher and students in distributed knowledge-building activities. Research into this process includes researchers exploring from the outside and teachers exploring from the inside (Bassey, 1995). Jaworski (2003) draws on the work of Wagner (1997) to elaborate a form of research which she calls co-learning, in which research on classroom learning is “conducted jointly by outsiders and insiders” (p 250). The w
Embedded Training for Complex Information Systems
One approach to providing affordable operator training in the workplace is to augment applications with intelligent embedded training systems (ETS). Intelligent embedded training is highly interactive: trainees practice realistic problem-solving tasks on the prime application with guidance and feedback from the training system. This article makes three contributions to the theory and technology of ETS design. First, we describe a framework based on Normanâs "stages of user activity" model for d
Component-Based Construction of a Science Learning Space
We present a vision for learning environments, called Science Learning Spaces, that are rich in engaging content and activities, provide constructive experiences in scientific process skills, and are as instructionally effective as a personal tutor. A Science Learning Space combines three independent software systems: 1) simulations in which experiments are run and data is collected, 2) representation construction tools in which data is analyzed and conceptual models are expressed and evaluated,
The defining characteristics of intelligent tutoring systems research: ITSs care, precisely
his paper argues that, despite the changes in philosophies and techniques that have occurred since ITS research began, there are continuous threads running through this research which define its essential and distinctive nature. In particular, ITSs are computer-based learning systems which attempt to adapt to the needs of learners and are therefore the only such systems which attempt to 'care' about learners in that sense. Also, ITS research is the only part of the general IT and education fie
The Importance of an Enhanced Problem Representation: On the Role of Elaborations in Physics Problem
This study of physics problem-solving identifies reasoning mechanisms that enable the problem-solver to achieve the transformation to a physics structure of the problem situation. Elaboration is explored as a mechanism in fulfilling this transformation by providing beginning problem-solvers with elaborations that they failed to infer. A card sorting experiment was employed in which two versions of physics problem descriptions had to be sorted. A comparison is made between proficient and weak stu
PRAXIS - Pervasive Rehabilitation of Aphasia with an eXtensible Interactive System
This thesis describes computer-assisted (CA) methods for the treatment of acquired language impairment in adult aphasics. A key design objective of this project was the elimination of the indirect manipulation of keyboard and mouse (in CA speech language therapy sessions) in favour of the direct manipulation of virtual and physical objects afforded by touchscreen display and radio frequency identification technology (RFID).
While computer-assisted treatment of aphasia has been used since the 196
Situational knowledge in physics: The case of electrodynamics
Major difficulties for a novice physics problem solver are how to interpret new problems and how to combine information given in the problem with information already known. A domain expert, by contrast, has the knowledge to take full advantage of problem features at a glance. It takes a long period of practice to acquire such situational knowledge, and it would be desirable for this to be taught more effectively. As a first step, this requires information on how situational knowledge differs acr
Physics learning with a computer Algebra systems: Towards a learning environment that promotes enhan
To become proficient problem-solvers, physics students need to form a coherent and flexible understanding of problem situations they are confronted with. This is important both for solving problems and for interpreting solutions. Still, many students have only a limited representation of the problems they are working on. Therefore, we devised an instructional approach to promote students' understanding of these problems, and to support them in forming associations between problem features and so
Learning physics with a computer algebra system
To become proficient problem-solvers, physics students need to form a coherent and flexible understanding of problem situations with which they are confronted. Still, many students have only a limited representation of the problems on which they are working. Therefore, an instructional approach was devised to promote students' understanding of these problems and to support them in forming associations between problem features and solution methods. The approach was based on using the computer alg
Co-Lab, design considerations for a collaborative inquiry learning environment
Co-Lab is a learning environment for collaborative inquiry learning in which learners can experiment, make models, consult background information and discuss their findings. The complex learning processes in such an environment need to be supported by appropriate features in the software. In this paper we report on how, based on existing literature and specific user and usability studies, we developed a set of design guidelines that were implemented in the software.
What Research Has to Say About Gender-Linked Differences in CMC and Does Elementary School ChildrenÂ
This paper first reviews the literature on computer mediated communication (CMC) to examine whether claims about gender-linked differences in specific attitudes, styles and content in CMC have been validated. Empirical studies were limited, with considerable variation in audiences, tasks, and contexts that was related to varied outcomes. The paper next describes an empirical study on the e-mail communication of elementary school children from ten Dutch classrooms. No gender-linked preference for
Problems and Opportunities of Learning together in a Virtual Learning Environment
This chapter explores new ways of collaborative learning in a virtual learning environment based on our acquisition of knowledge from previous experience. We identify both the problems faced in real collaborative learning practices and the ways these problems can be overcome and become opportunities for more efficient learning. These issues concern pedagogical, organisational and technical elements and constraints that influence the successful application of collaborative learning in distance ed
A Framework for Assessing Self, Peer and Group Performance in e-Learning
In this chapter we propose a framework that supports the analysis and assessment of collaborative learning of online groups of students working on a complex task (software project, or case study) in a real web-based, distance learning context. On the one hand, our approach is based on principled evaluation criteria that involve and measure a variety of elements and factors as well as on a combination of a basic qualitative process and a quantitative method that provide a grounded and holistic fr
A Neural Approach for Modeling the Inference of Awareness in Computer-Supported Collaboration
Individuals interacting in a computer supported collaborative learning (CSCL) environment produce a variety of information elements during their participation; these information elements usually have a complex structure and semantics, which make it rather difficult to find out the behavioral attitudes and profiles of the users involved. This work provides a model that can be used to discover awareness information lying underneath multi-user interaction. This information is initially captured in
Designing biases that augment socio-cognitive interactions
This chapter questions the assumption that the best environment for computer-supported collaborative learning is the one that most closely reproduces the features of face-to-face collaboration. Empirical studies have failed to establish the superiority of group interaction with richer media. Instead, the chapter explores media features that do not exist in face-to-face interactions and explains how these features might augment group cognition. The first feature, the persistency of the informatio
Virtual Learning Environments
Is the concept of 'virtual learning environment' just a popular label to describe any educational software? No, the concept includes several interesting features that justify the use of a specific label. We review these features in the first part of our contribution. Do these features guarantee pedagogical effects? No, we review in the second some potential contributions of virtual learning environments.Turning potential effects into actual outcomes is the challenge of designers.
Sharing solutions: persistence and grounding in multi-modal collaborative problem solving
This article reports on an exploratory study of the relationship between grounding and problem solving in multimodal computer-mediated collaboration. This article examines two different media, a shared whiteboard and a MOO environment that includes a text chat facility. A study was done on how the acknowledgment rate (how often partners give feedback of having perceived, understood, and accepted partner's contributions) varies according to the media and the content of interactions. It was expect
Towards an Open Grid Marketplace Framework for Resources Trade
A challenge of Grid computing is to provide automated support for the creation and exploitation of virtual organisations (VOs), involving individuals and different autonomous organizations, to which resources are pooled from potentially diverse origins. In the context of the presented work, virtual organizations trade grid resources and services according to economic models in electronic marketplaces. Thus in this paper we propose GRIMP (Grid Marketplace), a generic framework that provides servi
Mechanisms of common ground in case-based web-discussions in teacher education
Previous studies suggest that before the participants in Web-based conferencing can reach deeper level interaction and learning, they have to gain an adequate level of common ground in terms of shared mutual understanding, knowledge, beliefs, assumptions, and presuppositions (Clark & Schaefer, 1989; Dillenbourg, 1999). In this paper, the main purpose is to explore how participants establish and maintain common ground in order to reach deeper level interaction in case-based Web-discussions. The s
WWG: a Distributed Infrastructure for Learning in Groups
This paper describes the experiences of learning and working in groups on the Computer Science studies at Virtual Campus of the Open University of Catalunya. Two communities have used a web based shared workspace tool to a) coordinate the task of tutors of a computer architecture course, and b) a problem based collaborative learning project with software engineering students. These experiences have lead to the design of WWG: a distributed infrastructure for distance learning in groups at Interne
