A symbolic manipulator to introduce pupils to algebra theory
Within the theoretical framework of Vygotsky's theory, the paper presents a new algebra software. The main features of the software are described and their potentialities are discussed. According to the Vygotskian theory, expressions and commands may be thought as external signs of the Algebraic theory, and as such, they may become instruments of semiotic mediation: In other terms they can be used by the teacher, in the concrete realisation of classroom activity, according to the motive of intr
Randomness and LEGO robots
This paper reports on a long term experiment concerning the introduction of 7th grade pupils to the concept of randomness. Pupils are involved in activities with Lego robots, and in the joint enterprise of writing an Encyclopaedia. The main lines of the experiment are provided, together with experimental data, highlighting how some specific elements of the chosen educational approach influenced the evolution of pupils' mastery of the concept of randomness.
Distance learning meets Open Source
Most of the current German concepts for distance learning are still based on written study material with complementary face-to-face sessions. Modern e-learning tools are not as frequently in use as one might think or as it is often demanded. This article focuses on the obstacles that occur in the daily work with e-learning tools and which hinder the further spreading of e-learning on college level. One of the main problems is that study material as well as concepts have to be transformed in a w
Metacognition in joint discussion: an analysis of the patterns of interaction and the metacognitive
The aim of this study was to examine metacognition in computer-supported collaborative problem solving. The subjects of the study were 13-year-old Finnish secondary school students (N=16). The Knowledge Forum learning environment was used to support student pairs’ problem-solving task involving polygons in a geometry course. The data consist of the student pairs’ posted computer notes (n=95). To examine metacognition in a social context in the networked discussions, the features and patterns

The Aplusix-Editor: A New Kind of Software for the Learning of Algebra
The first part of the paper presents our conception of a new kind of software for helping students to learn algebra. Such software has three main characteristics. First it includes an advanced editor that allows the student to build easily algebraic expressions. Second it reifies the student's reasoning as a tree. Third it verifies the student's calculations. In the second part, we present the Aplusix-Editor, a system of that kind that we have realised, and we describe the first tests of this sy
Educational Knowledge Based Environment
In this paper a knowledge based environment is represented which facilitates easy creation and preparation of wide range of educational software. The heart of the environment is the knowledge representation tool providing a hybrid knowledge representation formalism combining frames, production rules and logic. The environment is built on the basis of the logic programming language Prolog.
User Interfaces for a Virtual Learning Environment: Two Study Cases
A recent powerful idea in the design of Web-based learning environments is the usage of virtual places. The employment of interface metaphors is one of the approaches enabling inexperienced users to feel comfortable in such virtual environments. We have designed a Virtual Environment for Distance Education and Training (VEDET), which provides basic virtual spaces, resources, and services. In this paper we discuss the user interface of two Web-based distance learning courses Business on the Inter
Socio-cognitive engineering is a framework for the human-centred design of technology-based systems to enhance human knowledge working, decision making, collaboration and learning. Like user-centred design, it draws on the knowledge of potential users and involves them in the design process. But it extends beyond individual users to analyse the activity systems of people and their interaction with technology, including their social interactions, styles and strategies of working, and language and
Vers une approche déclarative pour les logiciels de dessins géométriques
Cet article est consacré à la conception d'un environnement d'apprentissage de la géométrie orienté vers la manipulation directe de figures géométriques. À travers deux exemples d'activités, proposées en classe, on distingue les notions de construction géométriques, de spécification, et de manipulation directe. Dans le cadre ainsi défini, nous présentons notre approche. Elle consiste à intégrer des mécanismes et la méthodologie de l'intelligence artificielle dans un logic
Using domain-specific and generic knowledge to support discovery learning about geometrical optics i
Students encounter many obstacles during scientific discovery learning with computer-based simulations. It is hypothesized that an effective type of support, that does not interfere with the scientific discovery learning process, should be delivered on a ‘just-in-time’ base. This paper explores the effect of facilitating access to knowledge and skills through just-in-time information. An experiment was conducted in which a group of students who worked with a computer simulation on geometrica
Two Years Of Use Of The Aplusix System
APLUSIX is a learning environment for helping students to learn algebra. This system is designed and developed in the IMAG-Leibniz laboratory. Its basic training mode consists of letting the students perform their owns calculations, thanks to a two-dimensions editor of algebraic expressions, providing feedback on the correctness of the calculations and on the end of the resolution. APLUSIX has now been used for two years at school, in different contexts. One use was made by four teachers during
Designing for cross-cultural web-based knowledge building
This paper describes the iterative design of a web-based collaborative workspace used in educational practice, called WebReports. The systemâs unique feature is that it allows participants to discuss mathematical and scientific concepts using programmed animated and interactive models of their ideas. Rather than focusing on the specific features of the collaboration tool, we analyze it as part of a constructionist activity system. We describe the context in which the system was developed an
