There is a strong push from within mathematics education reform to incorporate representations in math classrooms (Behr, Harel, Post, & Lesh, 1993; Kieren, 1993; NCTM, 2000). However, questions regarding what representations should be used (for a given topic) and how representations should be used (such that students gain a deep understanding of…

Information technology (IT) has the potential to improve the clinical learning environment. The extent to which IT enhances or detracts from healthcare professionals' role performance can be expected to affect both student learning and patient outcomes. This study evaluated nursing students' satisfaction with a novel compartmental Picture…

The research described in this paper is concentrated on the demand for high quality interchangeable knowledge objects capable of supporting dynamic learning initiatives. The general metadata models (Dublin Core, IMS, LOM, SCORM) for knowledge objects enrichment are reviewed and a critique is provided in order to claim the importance of the…

Discusses the use of technology to enhance student learning based on learning processes. Topics include knowledge chunks, assimilation and repetition, cognitive schema, Bloom's Taxonomy, students manipulating the learning environment, student productivity, and checkpoints for evaluating technology utilization. (LRW)

Discusses multiple representations and multimedia learning environments; describes a functional taxonomy of MERs (multiple external representations); and considers how MERs are used to support cognitive processes in learning and problem solving with computers. (Contains 41 references.) (Author/LRW)

Describes an exploratory study on the acquisition and use of knowledge representation skills and structures by sixth-graders, supported by a computer-based learning environment. Results indicated that symbolic structures can be taught successfully, and that students using them in the context of instructional tasks perform at the higher band of…

Investigates the effects of context-weak versus context-strong tasks and learning style on the citation-frequencies and citation-percentages of four mental models (semantic networks, concept maps, frames/scripts, and schemata) students perceived to be inherent in a hypermedia learning environment. (Author/AEF)

Computer-based learning environments commonly comprise symbolic as well as static and dynamic pictorial representations, frequently combined with the possibility of modifying them interactively. While multiple, dynamic and interactive external representations have the potential to improve learning in various ways, they also place specific demands…

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…

Conceptual learning of 13 graduate students was studied during a six-week course using the Internet for collaborative learning of online articles. Five groups were formed with each creating a knowledge map during the first and fifth week of the course. Multidimensional scaling analysis was used to study change in each group's mapping over time to…
