This journal article discusses Advanced Mathematical Thinking (AMT) and how to enhance it. AMT is ability in representing, abstracting, creative thinking, and mathematical proving. The importance of AMT ability development in accord with government expectation who realize about the importance of mathematical competency mastery for student's life.…

Computer-supported collaboration by spatially distributed group members still involves interaction problems within the group. This article presents an empirical study investigating the question of whether computer-supported collaborative problem solving by spatially distributed group members can be fostered by evoking knowledge and information…

This article presents the design and evaluation of a tool for inspecting conceptual models of system behaviour. The basis for this research is the Garp framework for qualitative simulation. This framework includes modelling primitives, such as entities, quantities and causal dependencies, which are combined into model fragments and scenarios.…

This study examined the representation of knowledge in text writing in 20 ten-year-old children and 20 adults in the Netherlands. The research analyzed the use of clause linking devices to compose larger text units. Special attention was given to the use of causal relational markers and the extent to which causal relations within the texts matched…

People find difficulty in performing syllogistic reasoning. This paper outlines some reasons for poor syllogistic reasoning. Representational systems (RS) used in presenting and evaluating syllogisms can be distinguished in terms of attributes such as specificity, expressiveness, and abstraction. Graphical RSs have pedagogical potential because of…

What kind of influence does the structure of an educational hypermedia system have on the way its users understand its contents and organize the knowledge they acquire through its browsing? In this article, this already much discussed question, situated at the boundary between semiotics and cognitive science, is revisited in the light of results…

Coded experience and effective semiotic systems, organizations of patterns of signs that comprise a system of meaning, have proved essential for the propagation of knowledge. In education, communication via semiotic systems forms an important role in guiding children toward the effective use of information and techniques, and it is important that…

A movement of educational change in Portugal aimed at giving schools larger autonomy in curricular decisions is described. In reconceptualizing curriculum, the concepts of competence and innovation played a central role. An analysis of the curriculum development process is included and some suggestions are offered for future research and debate.…

The field of higher education shows a jumble of alliances between fellow institutes. The alliances are strategic in kind and serve an economy-of-scales concept. A large scale is a prerequisite for allocating the budgets for new educational methods and technologies in order to keep the educational services up-to-date. All too often, however,…

This study reports on the historical conceptualization among Finnish 12-13 year-olds who were given a projective task to yield historical thinking. The case study examines expressions the subjects used and which were studied qualitatively, using "chunks of meaning" as units of analysis, in regard to both their meaning- content and their…

An examination of Dutch research on legal case solving revealed that few law students get systematic instruction or testing in the technique of legal problem solving. The research being conducted at the Department of Computer Science and Law at the University of Amsterdam focuses on identifying the different functions in legal reasoning tasks in…

This paper focuses on issues of representation and interaction styles that are relevant considerations in the design and analysis of hypermedia learning environments. Analysis is supported by examples from the "HUGH" series of studies involving learners in reasoning about formal hypermedia representations. The representational issues include…

This set of papers offers insights into some of the major developments in the field of classification and knowledge organization, and highlights many of the fundamental changes in views and theories which have taken place during the last 40 years. This document begins with a series of reminiscences from former delegates of the first International…
