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
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
Instruments of semiotic mediation in algebra, an example
The paper presents a class discussion which was set up within a long term experiment concerning the use of a software, L'Algebrista, to introduce pupils to theoretical thinking and symbolic manipulation. From the analysis of the discussion we will illustrate some aspects of how a teacher can use an instrument of semiotic mediation in order to guide the genesis and evolution of new concepts.
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. We analyze the students' processes of mea
La natura della mediazione offerta dai sistemi basati su micromondi all’apprendimento della matema
In questo articolo prenderemo in esame il sistema ARI-LAB che abbiamo realizzato per sostenere gli alunni nello sviluppo di capacità nel problem solving aritmetico e cercheremo di descrivere alcune caratteristiche che questo software rende disponibile con il fine di valutarne le potenzialità sul terreno didattico. Nel fare ciò assumeremo due riferimenti: da una parte l'analisi della natura del sapere coinvolto nel problem solving aritmetico, descritta nella prima parte di questo lavoro, dall'
Selected Papers from the Kaleidoscope Convergence Workshop
To foster synergy between research on collaborative, mobile and inquiry learning and between different scientific and methodological perspectives (namely, educational design, psychology and computer science) and to strengthen the cohesion of the community, the Kaleidoscope network has decided to organise a âConvergence Workshopâ in conjunction with the 2006 Contractors' General Assembly in Amsterdam, Dec. 4-6. The two fields of collaborative and inquiry learning have bee
TELMA Cross Experiment Guidelines
This document contains the guidelines developed by members of TELMA as a means for planning, conducting, and analysing a cross experiment aimed at contributing to the construction of a shared research perspective among TELMA teams . This is the product of the PhD students and young researchers that brought forward the whole activity. The actual experimental phase was proceeded by a reflective phase in which an agreement was achieved on what research questions to address during the experiment. O
Kaleidoscope JEIRP on Learning Patterns for the Design and Deployment of Mathematical Games: Final R
Over the last few years have witnessed a growing recognition of the educational potential of computer games. However, it is generally agreed that the process of designing and deploying TEL resources generally and games for mathematical learning specifically is a difficult task. The Kaleidoscope project, "Learning patterns for the design and deployment of mathematical games", aims to investigate this problem. We work from the premise that designing and deploying games for mathematical learning re
Studying participation networks in collaboration using mixed methods
This paper describes the application of a mixed-evaluation method, published elsewhere, to three different learning scenarios. The method defines how to combine social network analysis with qualitative and quantitative analysis in order to study participatory aspects of learning in CSCL contexts. The three case studies include a course-long, blended learning experience evaluated as the course develops; a course-long, distance learning experience evaluated at the end of the course; and a synchron
Combining qualitative evaluation and social network analysis for the study of classroom social inter
Studying and evaluating real experiences that promote active and collaborative learning is a crucial field in CSCL. Major issues that remain unsolved deal with the merging of qualitative and quantitative methods and data, especially in educational settings that involve both physical and computer-supported collaboration. In this paper we present a mixed evaluation method that combines traditional sources of data with computer logs, and integrates quantitative statistics, qualitative data analysis
Evaluation of ITS Design: The Case of Shiva-géographe
This paper analyses the relationships between a conceptual analysis from the point of view of geographers and the conceptual organisation resulting from the ECAL processing of the implemented specifications of the SHIVA-géographe authors.
Using online role play to teach internet safety awareness
This paper reports on an evaluation of Net-Detectives, a creative online role play activity aimed at 9–12 year olds. Net-Detectives forms part of Kidsmart, an Internet awareness programme aimed at school children. It was evaluated through a multiple method data collection using questionnaire surveys, follow up telephone interviews with teachers and observation in use in three UK schools during the summer term of 2003. All sources of data collected agreed that a number of benefits arise from p
Music Composition Lessons: the multimodal affordances of technology
This article seeks to investigate the multimodal affordances presented by music software and how it can provide new opportunities for students to engage with composition work in the classroom. It aims to broaden the scope of current research into classroom composition using technology, through a study of students' environments and compositional processes as seen from these new perspectives. The authors believe there is a now a need for a reconsideration of the scope of multimodal enquiry in the
Representing Domain Knowledge by Concept Maps: How to Validate Them?
For one and the same domain several alternative concept maps may exist, originating from different world views or purposes. Some of these concept maps may be valid, however not all of them. Thus, strategies for empirically and objectively validating concept maps in the respective context are necessary. We outline two methodological approaches for empirically validating concept maps, one for giving evidence of content validity and one for application validity. One procedure is to validate a given
Formalismes pour une mémoire de formation à base d’annotations : articuler sémantique implicite
Cet article a pour objet de présenter les formalismes définis pour des mémoires de formation à base d’annotations au sein du projet MICA. Il explicite les objectifs de la recherche et les exigences que cela apporte sur les outils visés. Une étude des travaux de la littérature sur les annotations et leurs formalismes montre qu’ils ne couvrent que de façon très limitée nos objectifs. Nous présentons alors les formalismes que nous avons développés, en structurant l’objet d’anno
Semantic Annotation Tools for Learning Material
This paper aims at providing the specification for semantic annota-tion tools for e-learning. From the specific requirements of annotating learning material, we categorize and evaluate the existing annotation tools, mainly gen-eral 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.
PDAs and Handhelds: ICT at your side and not in your face
This paper stems from a trial at the Graduate School of Education in the University of Bristol supported by the Training and Development Agency for Schools (TDA) and set up to evaluate the potential of personal digital assistants with internet access to support initial teacher training (ITT) students in science. Fourteen students were given PDAs selected to represent the range of then currently available PDAs with mobile phone connectivity in the UK. As a result the following areas were identifi
A model for negotiation in teaching-learning dialogues
Despite the fact that a number of researchers from a wide variety of theoretical perspectives have claimed that negotiation in dialogue is fundamental in learning, little research has been based on a precise notion of what negotiation is and how it relates to learning. This paper describes a model for negotiation, based on analysis of teacher-student and learner-learner dialogues. After discussion of illustrative examples and review of related research, negotiations are defined in terms of four
