In these studies, a vegetable can containing fluid was swung as a pendulum by supporting its end-lips with a pair of knife edges. The motion was measured with a capacitive sensor and the logarithmic decrement in free decay was estimated from computer-collected records. Measurements performed with nine different homogeneous liquids, distributed…

Present Educational Modelling Languages are used to formally specify abstract learning scenarios in a machine-interpretable format. Current tooling does not provide teachers/designers with some graphical facilities to help them in reusing existent scenarios. They need human-readable representations. This paper discusses the UML4LD experimental…

Two experiments (one using models and diagrams, one using slides) were carried out to investigate how remedial instruction may be given to students who have difficulties in visualizing the diagrammatic representation of a three-dimensional structure after the structure has been rotated. (Author/BW)

This study examined the effect of covert modeling on communication apprehension, public speaking anxiety, and communication competence. Students identified as highly communication apprehensive received covert modeling, a technique in which one first observes a model doing a behavior, then visualizes oneself performing the behavior and obtaining a…

Describes a unit of study for poetry which draws an analogy between the delivery of verbal images of poems and the visual images in rock music videos. Reports that students were able to see imagery in poems and to reflect images into meaning. (KEH)

Discusses and examines two approaches to concept-based retrieval of hypermedia information that improve a user's ability to navigate large systems--term indexing with semantically coupled thesauri and semantic hyperindexing. Visualization of index structures is discussed, and an example, the Cube of Contents retrieval model for the "Active…

Discusses information visualization and cocitation analysis and demonstrates the use of an integrative approach to visualizing and tracking the development of competing scientific paradigms. Assumes that a cluster of highly cited and cocited scientific publications in a cocitation network represents the core of a predominant scientific paradigm.…

Considerable discussion and debate have been devoted to the extent and nature of structural or functional correspondence between internal representations and their external visual counterparts. An analogue representation or process is one in which the relational structure of external events is preserved in the corresponding internal…

Describes ways of projecting stereoscopic images of geologic environments for students with difficulty reasoning in three-dimensions. The photographic procedures needed to produce stereo slides are included. (MA)

To explore the relationship between spatial ability and both image quality and image process efficiency, 79 subjects completed spatial tests, imagery questionnaires, and laboratory tasks. Laboratory measures of process efficiency and image quality were strongly related to spatial test performance and weakly related to one another. (Author/BW)

Describes procedure for promoting specific aspects of ego development in groups. Notes that procedure employs two visualization and art experiences and is guided by two therapeutic models, transactional analysis and existential therapy. Includes description of Loevinger's conception of ego development which provides larger framework in which to…

Discusses a process to guide technical writers engaged in writing a script for a video production on a technical subject. Offers an example of the development of such a script from a video demonstrating a surgical procedure. (SR)

Empirical studies that focus on the impact of three-dimensional (3D) visualizations on learning are to date rare and inconsistent. According to the ability-as-enhancer hypothesis, high spatial ability learners should benefit particularly as they have enough cognitive capacity left for mental model construction. In contrast, the…

G. Wolford's perturbation model of letter identification is designed to account for identification errors of briefly presented characters. Its chief assumptions are that features are extracted in parallel, that some of these features become perturbed or mislocalized, and that mislocalizations are more likely to occur in the direction of the fovea…
