Cognitive processes in solving variants of computer-based problems used in logic teaching
The effect of two instructional variables, visualisation and manipulation of objects, in learning to use the logical connective, conditional, was investigated. Instructions for 66 first-year social science students were varied in the computer-based learning environment Tarski's World, designed for teaching first-order logic (Barwise & Etchemendy, 1992. The language of first-order logic: including the Microsoft Windows program Tarski's World 4.0 for use with IBM-compatible computers. Stanford, CA

Learning opportunities in a kindergarten about the concept of probability
In this paper we describe the studentsÂ’ mathematical learning in a kindergarten during a classroom teaching experiment about the concept of probability. We present and analyze the learning opportunities that were created in the classroom as the children tried to resolve their problems, to reason mathematically and to communicate their thinking to others. The results of the research showed that kindergarten children made considerable progress in their probabilistic thinking,when they accepted th

Meanings for Fraction as Number - Measure by Exploring the Number Line
Construction of meanings for fraction as number-measure is studied during the implementation of exploratory tasks concerning comparison and ordering of fractions as well as operations with fractions. 12-year-old students were working collaboratively in groups of two with software that combines graphical and symbolic notation of fractions represented as points on the number line. Fractions as points and segments, ordering fractions as part of kinesthetic activities and abstracting the scaling of

Adaptive and context-aware scenarios for technology-enhanced learning system based on a didactical t
Among the main issues of future technology-enhanced learning systems, we can mention the following ones: the ability to reuse learning resources (learning objects, tools and services) from large repositories, to take into account the context and to allow dynamic adaptation to different learners based on substantial advances in pedagogical theories and knowledge models. In our framework, the goal of scenarios is to describe the learning and tutoring activities to acquire some knowledge domain (fo

Obstacles to the development of conceptual understanding in observational astronomy: the case of spa
Simple everyday phenomena like the day - night cycle and the sequence of four seasons are taught at the higher level of elementary education and the lower level of secondary education in Cyprus. Even though there is no specific subject dedicated to Astronomy or spatial reasoning, the day Â– night cycle, the sequence of the four seasons and the sequence of the lunar phases are part of the national curriculum of Geography. For this reason, the construction of conceptual understanding in basic Astr

Synchronous computer mediated collaborative activities among collocated students: Conditions that ma
Synchronous collaborative activities are usually studied in conditions where teachers and students are physically separated. Is there any possibility to apply these activities when all participants are collocated? Does this collocated collaboration setting seems meaningful and for what reasons? Is the quality of learning and teaching process satisfactory high? Under what conditions? The present research explores the previous questions. More specifically, it explores synchronous computer mediated

An Algebra Subsystem for Diagnosing Students' Input in a Physics Tutoring System
To help a student in an introductory physics course do quantitative homework problems, an intelligent tutoring system must determine information of an algebraic nature. This paper describes a subsystem which resolves such questions for Andes2. The capabilities of the subsystem would be useful for any ITS which deals with problems involving complex systems of equations. This subsystem is capable of 1) solving the systems of equations at the level of introductory physics problems, 2) checking the

Standard-compliant Scenario Building with Theoretical Justification in a Theory-aware Authoring Tool
Nowadays standard technologies play important roles in enhancing sharability, reusability and interoperability of learning contents. However, there is a lack of pedagogical justification of the contents implemented with the standards. This paper discusses the standard-compliance of our ontology-based modeling framework and how the framework gives theoretical justification to standard-compliant learning/instructional scenarios in a theory-aware authoring tool.,Poster in 13th International Confere

The Diver Project: Interactive Digital Video Repurposing
The digital interactive video exploration and reflection (Diver) system lets users create virtual pathways through existing video content using a virtual camera and an annotation window for commentary. Users can post their Dives to the WebDiver server system to generate active collaboration, further repurposing, and discussion. Although our current work focuses on video records in learning research and educational practices, Diver can aid collaborative analysis of a broad array of visual data re

Addressing the Challenges of Inquiry-Based Learning Through Technology and Curriculum Design
Inquiry experiences can provide valuable opportunities for students to improve their understanding of both science content and scientific practices. However, the implementation of inquiry learning in classrooms presents a number of significant challenges. We have been exploring these challenges through a program of research on the use of scientific visualization technologies to support inquiry-based learning in the geosciences. In this article, we describe 5 significant challenges to implementin

Hypermedia as a means for learning and for thinking about learning
This paper is about the design and realization of an experimentation with a hypermedial system, IPER-3, facing the three â€˜classicalâ€™ problems in the history of mathematics (trisection of the angle, quadrature of the circle, duplication of the cube) and some issues which have developed around them. The aim of the work is to study the opportunities provided by hypermedial systems in dealing with topics of interest for the training of teachers and/or for class work, exploiting the possibility o

COML (Classroom Orchestration Modelling Language) and Scenarios Designer: Toolsets to Facilitate Col
In a one-to-one collaborative learning classroom supported by ubiquitous computing, teachers require tools that allow them to design of learning scenarios, and to manage and monitor the activities happening in the classroom. Our project proposes an architecture for a classroom management system and a scenarios designer tool, both based on a Classroom Orchestration Modelling Language (COML), to support these requirements. We are developing and testing this with the GroupScribbles software using a

Computational Mathetics: Towards a Science of Learning Systems Design
The aim of this report is simply to help put the design of computer-based systems to support learning on a more scientific footing. The aim is simply stated, but its achievement is more difficult. For one thing, it is not at all obvious what "more scientific" means in this context. However, it is essential for AI-ED research to take better account of the concepts of 'situation', 'context', 'community', 'discourse', 'social learning', and so on, but these terms need to be defined, not used as man

A device helping learners to self-assess themselves
In this paper, we introduce the architecture of an environment, which aims at helping learners in their self-assessment process. We show how we integrated three systems to build an experimental device based on this architecture. We then present the experiment we conducted to show the utility of this device and also to validate our hypothesis that it is easier for learners to self-assess themselves from an exercises-point of view than from a knowledge-point of view.
