This paper addresses how to help learners navigate in existing Web-based learning resources. In order to resolve this issue, a learner-centered navigation path-planning model is proposed. The main objective is to provide learners with a path planning space in which they can see through hyperspace to plan a navigation path. This paper describes an assistant system called Planning Assistant (PA),...

A functional representation of the hyperspace monad, based on the semilattice structure of function space, is constructed.

The 'hyperspace effect' in vowel perception may be taken as evidence that adaptive dispersion is an active perceptual process. However, a previous study tested for adaptive dispersion in isolated vowel stimuli spoken in a voice unfamiliar to the listeners. The experiment reported in this paper addressed both of these potential concerns and found that both consonant context and talker familiarit...

It is shown that there is no Whitney map on the hyperspace 2x for nonmetrizable Hausdorff compact spaces X. Examples are presented of non-metrizable continua X which admit and ones which do not admit a Whitney map for C(X). Given a Hausdorff compact space X, we consider the space 2x of all non-empty compact subsets of X equipped with the Vietoris topology. Any subspace H (X) of the space 2x is ...

The aim of the paper is to first investigate some properties of the hyperspace $theta(X)$, and then in the next article it deals with some detailed study of a special type of subspace $downarrowtheta C(X)$ of the space $theta (Xtimes mathbb I)$.

Various strategies for remapping hyperspace associated with two iterative genetic algorithms are reviewed, compared and empirically tested on a particular \real-world" problem. Both algorithms reduce the hypercube at each iteration such that each new mapping samples only subpartitions of the search space. Delta coding remaps the search space at each iteration by sampling the subspace numericall...

Agent-oriented approach is increasingly showing its magic power in a diversity of fields, specifically, ubiquitous computing and smart environment. Meanwhile, it is considered the next creative issue is to interconnect and integrate isolated smart spaces in real world together into a higher level space known as a hyperspace. In this paper, an agent-oriented architecture, which involves the tech...

Hypermedia/hypertexts generally provide learners with hyperspace where they can explore domain concepts/knowledge in a self-directed way (Conklin 1988). Exploration often involves making cognitive efforts to construct their knowledge with the contents that they have explored. These cognitive efforts would enhance learning (Carroll et al. 1985; Kashihara et al. 1997). However, learners often fai...

How to help learners plan a navigation path on the Web is an important issue in web-based learning/education. Our approach to this issue is to allow the learners to preview a sequence of web pages as navigation path plan. In this paper, we introduce an assistant system that enables learners to plan the navigation path in a self-directed way before navigating hyperspace provided by web-based lea...
