This paper proposes a computer-aided teaching model using knowledge graph construction and learning path recommendation. It first creates a multimodal knowledge graph to illustrate complex relationships among knowledge. Learning elements and sequences are then used to form time sequences stored as directed graphs, supporting flexible path…

Processing of multiple representations in multimedia learning environments is considered to help learners obtain a more complete overview of the domain and gain deeper knowledge. This is based on the idea that relating and translating different representations leads to reflection beyond the boundaries and details of the separate representations.…

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…

This paper reports on a case-study design experiment in the domain of fraction as number-measure. We designed and implemented a set of exploratory tasks concerning comparison and ordering of fractions as well as operations with fractions. Two groups of 12-year-old students worked collaboratively using paper and pencil as well as a specially…

While different approaches to evaluation will yield different results, depending on the purpose of the evaluation this article describes an evaluation approach that was aimed at investigation of the mental models of users of the programme. The study was driven by questions about the differences in mental models of the instructional designers and…

Discussion of computers as mindtools focuses on semantic networks and expert systems that help learners build a representation of what they know by designing their own knowledge bases. Describes a study of undergraduates that examined the effects of building semantic networks on the construction of expert systems. (Author/LRW)

This paper covers an experiment designed to investigate the relationship between the didactical setting and learning effects with animations. We investigated whether the cognitive load imposed by animations could be reduced when the students could control the flow of the animation. We did not find an effect due to the fact that the students did…

This paper presents the design, features and pilot evaluation study of a web-based environment--the SORTING environment--for the learning of sorting algorithms by secondary level education students. The design of this environment is based on modeling methodology, taking into account modern constructivist and social theories of learning while at…

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…

Computer-based learning environments are proliferating in an effort to make more resources available to more students in more timely and individualized ways without overtaxing diminishing budgets. Many computer-based learning environments are designed to facilitate meaningful interaction, however, interactivity is only one of the factors that…

Discussion of explanations and knowledge representation within knowledge-based systems focuses on the development of an expert system for purification of proteins in a Swedish laboratory. Topics include domain conceptualization; a multiple-explanation construction model; a study of laboratory staff that investigated construed explanations; and…

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…

This paper presents the research and development of knowledge management system for Internet based intellectual assets to leverage the learning process for individual learners. The literature review reveals that corporate solutions of knowledge management are not directly applicable due to the lack of adaptivity needed to provide individualized…

A method to facilitate collaborative learning in complex learning environments was developed and evaluated. Sixteen college students of educational science were given the CoStructure-Tool, a task-specific computer-based tool developed on the basis of concept mapping techniques to support the processes of knowledge construction in collaborative…

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.
