Anchored Interactive Learning Environments
Advances in computer technology and multi-media systems have led to widespread interest in computer-based instruction and learning environments. The use of video, animation, graphics, and simulation allow the presentation of material in realistic contexts, thus addressing the problems of inert knowledge while promoting constructive and generative learning. But the true potential and benefits of these systems are yet to be realized. Cognitive studies on learning and transfer suggest that concepts
From mirroring to guiding: A review of the state of art technology for supporting collaborative lear
We review systems that support the management of collaborative interaction, and propose a classification framework built on a simple model of coaching. Our framework distinguishes between mirroring systems, which display basic actions to collaborators, metacognitive tools, which represent the state of interaction via a set of key indicators, and coaching systems, which offer advice based on an interpretation of those indicators. The reviewed systems are further characterized by the type of inter
From MASK Knowledge Management Methodology to Learning Activities Described with IMS – LD
In this paper we present how the way knowledge capitalized using the Knowledge Management Mask methodology can be used to design E-learning activities by matching Mask models and the concepts proposed by the IMS-Learning Design modelling language. Our study consists in highlighting the e-learning aspects encapsulated in these MASK models carried out around a domain of activity, via a writing these elements in the description language IMS - Learning Design; in a preoccupation of reusability and r

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 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
Progressive computer-supported modelling as a learner activity: A tool for understanding
Recently, computer modelling has been added as a new topic in final examination programmes for physics and mathematics in the Netherlands. It involves constructing, running, evaluating, and extending simulation models. Currently, we are developing curriculum materials to support this new topic. In the course of our work, we became convinced that computer-supported modelling should be an integrated part of the curriculum from early on. Constructing a model involves identifying components, propert
Embedding email in primary schools: developing a tool for collective reflection
Reflection is an important aspect of learning in groups. In collective moments of reflection, learners can share and compare their ideas with others, and by doing so can reach an articulated and personal understanding of a learning task and domain. In the research presented here, e-mail is examined as a means for reflection in the context of group learning. In two design experiments, an e-mail tool is developed that seeks to (1) support collective reflection, and (2) overcome practical problems
Providing Efficient Event Information Management to CSCL Applications
This work aims to explore the importance of carrying out an efficient management of the event information generated from CSCL applications during the collaborative learning process. The achievement of this task first involves the design of a conceptual model of collaborative learning interaction that captures and distinguishes several high-level collaborative learning processes, which in turns leads to a computational model. To achieve that, we first define the main types of event information ge
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
21F.705 Oral Communication in Spanish (MIT)
A second-year intermediate course that includes vocabulary enhancement and limited review of selected points of grammar. Focuses on listening comprehension and speaking, with group activities, discussions and individual oral reports based on readings, films, music and art.
I*teach methodology in school practice
One of the assumptions of secondary education is that students are to acquire numerous ICT-related skills. The computer has become an essential element of live, both at school and outside it. Using ICT tools students can structure their knowledge, prepare images, create banks of data and analyze it, write reports and other text documents. Electronic mail, discussion lists, forums and other online applications facilitate communication and cooperation. World Wide Web gives an easy access to immens
Internet Scout Project
The US Department of Agriculture's Plants Database (last mentioned in the January 16, 1998 Scout Report) is continually adding improvements. Most recently, the Web sitehas added an advanced query to allow users to search for specific plant data based on many different search characteristics. This new feature is also user friendly; by clicking on any of the fields, a definition of the field is displayed. Also new are targeted links that allow you to link directly from a queried plant profile to o
ActiveMath: A Generic and Adaptive Web-Based Learning Environment
ActiveMath is a generic web-based learning system that dynamically generates interactive (mathematical) courses adapted to the student's goals, preferences, capabilities, and knowledge. The content is presented in a semantic XML-based format. For each user, the appropriate content is retrieved from a knowledge base and the course is generated individually according to pedagogical rules. Then the course is presented to the user via a standard web-browser. One of the exceptional features of Active
Supporting Social Interaction in an Intelligent Collaborative Learning System
Students learning effectively in groups encourage each other to ask questions, explain and justify their opinions, articulate their reasoning, and elaborate and reflect upon their knowledge. The benefits of collaborative learning, however, are only achieved by active, well-functioning teams. This paper presents a model of collaborative learning designed to help an intelligent collaborative learning system identify and target group interaction problem areas. The model describes potential indicato
Principles for designing Web searching instruction
Web searching is a timely topic which importance is recognized by researchers, educators and instructional designers. This paper aims to guide these practitioners in developing instructional materials for learning to search the Web. It does so by articulating ten design principles that attend to the content and presentation of Web searching instruction. These principles convey a mixture of insights gleaned from instructional theory, empirical research, and many hours of classroom experience. Tog
The effects of graphical overviews on exploratory behaviour and knowledge acquisition in hypertext e
One of the main and recognized problems of learning with hypertexts is that learners are easily distracted and end up ‘lost in hyperspace’. As a result, they do not acquire complete and adequate knowledge. In this study, we enhanced a hypertext environment with a graphical overview that represented the basic structure of the domain and we designed the layout in such a way that learners were unobtrusively encouraged to follow a sequence of exploration that followed the domain structure. This so
