Two major research streams of information science, bibliometric mapping and document retrieval combined in the literature visualization movement with the implementation of VIRI (visual information retrieval interface). The capability now exists to quickly map the citation images of thousands of persons through AuthorLink, to map displays of…

This article presents Virtual Radiopharmacy Laboratory (VR LAB), a virtual laboratory accessible through the Internet. VR LAB is designed and implemented in the framework of the VirRAD European project. This laboratory represents a 3D simulation of a radio-pharmacy laboratory, where learners, represented by 3D avatars, can experiment on…

In this article, the author describes his experience when Kathy Nichols contacted him seeking suggestions, recommendations--really anything he could think of--that might help her seize control of a bewildering and rapidly surging torrent of digital image files. The challenges that Nichols described interested him, and he felt they might be…

In spite of all the attention that the concept of learning objects has received in the education community, it remains poorly defined. This paper attempts to explore what may be a learning object other than some computer file catalogued in a digital library for reuse. Any debate about what a learning object may be is premature without a general…

Among the old-school resources that the digital age is making obsolete, or at least less consequential, count the chalkboard. For decades, the chalkboard was the focal point of all instruction, the big screen on which teachers wrote out and directed lesson after lesson after lesson. Today, while chalkboards still exist, they are losing their…

The word "suburbia" evokes a wealth of imagery such as model homes, spacious yards, and minivans from movies, commercials, print advertisements, and television shows. These Utopian ideas of suburbia are partly truth and partly myth. Popular media's powerful portrayal of suburbia can be traced back to the wholesome 1950s' and 1960s'…

Two studies were conducted to investigate the specificity of the relationship between preschoolers' emerging executive functioning skills and false belief understanding. Study 1 (N=44) showed that 3- to 5-year-olds' performance on an executive functioning task that required selective suppression of actions predicted performance on false belief…

In this activity students examine burrow casts to learn about burrowing animals and practice their math skills. Students compute the volume and average circumference of a burrow. They also determine whether a relationship exists between burrow volume and the size of the organism that created it. Students use science as inquiry as they analyze and…

Research suggests that the educational value of a media format depends upon the ways in which its representational affordances interact with complex features of the learning environment, including learner characteristics, content domains, pedagogical strategies, and cognitive and social processes. In the current study, we sought to understand some…

According to the National Council of Teachers of Mathematics (2000), children need to learn how to create and use mathematical diagrams to represent and reason about phenomena in the world. The author proposes a model of diagram literacy that includes six types of knowledge required for diagrammatic competence--implicit, construction, similarity,…

Considers effective dialogue between teacher and student essential for promoting meaningful learning in the classroom. Effective dialogue enables teachers and students to be active in the construction of shared understanding by making explicit the overlap between the perspectives held by students and teachers. Suggests that concept maps provide a…

Background: This project examined the intermodal perception of temporal synchrony in 16 young children (ages 4 to 6 years) with autism compared to a group of children without impairments matched on adaptive age, and a group of children with other developmental disabilities matched on chronological and adaptive age. Method: A preferential looking…

An important learning opportunity occurs during the question and answer (Q & A) session following student speeches. Not only do students benefit from the information conveyed in these speeches, but students also benefit from the cognitive stimulation the opportunity affords. Often, however, it seems that the Q & A session falls short of these…

Purpose: The purpose of this paper is to provide an overview of a particular approach for increasing knowledge creation in organisation. The paper provides a discussion of related concepts, processes, and a tool. Design/methodology/approach: This paper describes the reasons for drawing connectance diagrams, the process and the software. It also…

The current research examined performance of good and poor readers of Thai on two tasks that assess sensitivity to dynamic visual displays. Readers of Thai, a complex alphabetic script that nonetheless has a regular orthography, were chosen in order to contrast patterns of performance with readers of Korean Hangul (a similarly regular language but…
