Developing student spatial ability with 3D software applications

This paper reports on the design of a library of software applications for the teaching and learning of spatial geometry and visual thinking. The core objective of these applications is the development of a set of dynamic microworlds, which enables (i) students to construct, observe and manipulate configurations in space, (ii) students to study different solids and relates them to their corresponding nets, and (iii) students to promote their visualization skills through the process of constructing dynamic visual images. During the developmental process of software applications the key elements of spatial ability and visualization (mental images, external representations, processes, and abilities of visualization) are carefully taken into consideration

Rethinking Map Legends with Visualization

This design paper presents new guidance for creating map legends in a dynamic environment. Our contribution is a set of guidelines for legend design in a visualization context and a series of illustrative themes through which they may be expressed. These are demonstrated in an applications context through interactive software prototypes. The guidelines are derived from cartographic literature and in liaison with EDINA who provide digital mapping services for UK tertiary education. They enhance approaches to legend design that have evolved for static media with visualization by considering: selection, layout, symbols, position, dynamism and design and process. Broad visualization legend themes include: The Ground Truth Legend, The Legend as Statistical Graphic and The Map is the Legend. Together, these concepts enable us to augment legends with dynamic properties that address specific needs, rethink their nature and role and contribute to a wider re-evaluation of maps as artifacts of usage rather than statements of fact. EDINA has acquired funding to enhance their clients with visualization legends that use these concepts as a consequence of this work. The guidance applies to the design of a wide range of legends and keys used in cartography and information visualization

Use of the dynamic simulation to reduce handling complexity in the manufacturing process

Many companies have started using dynamic simulation as full support for their own optimization team to optimize business processes. The 3D visualization can facilitate understanding of the links among processes and their connections. It can significantly contribute to its appropriate implementation. which aims at saving costs, simplifying processes, introducing new or innovated processes, etc. Application field is not significant for the 3D visualization. Predictive simulation can be applied in any process, from storage. logistics, handling, through production line optimization to distribution. The submitted paper deals with the optimization of the production process regarding the reduction of handling demands for the company in the automotive industry. Businesses are currently facing an issue of handling complexity, which has a relatively high cost, depending on the amount of unnecessary and chaotic trips within production processes. It is necessary to modify the charging method in any change of production. This is connected with an increase of non-productive rides. The article introduces the possibility of a variant solution with the possibility to use dynamic simulation as a powerful tool for the process optimization.Web of Science141888

The Effectiveness Of Using Dynamic Visualization In Natural Science Learning To Improve Students' Understanding In Junior High Schools

Visualization can support an instructional process. Visualization consists of all types of nonverbal illustrations. The very rapidly computer technology enables the development of multimedia learning environment. This research was aimed at describing the effectiveness and attractiveness of the use of dynamic visualization in an instruction on transportation system and excretion in organisms. Sixty four students of grade 8 who consisted of 36 males and 28 females were used as the subjects of the research. The data of the research were collected in the form of pre-test and post-test scores in the students’ understanding of transportation system and excretion in organisms and in the attractiveness of the use of dynamic visualization in the instruction. Statistical test showed that the mean of the comprehension test before the use of dynamic visualization differed significantly from that after the use of dynamic visualization and that dynamic visualization was attractive to be used in the instruction. Hence, it can be concluded that dynamic visualization can enhance students’ understanding

DyVProMo - A Lightweight Web-Based Tool for the Dynamic Visualization of Additional Information in Business Process Models

Business process models represent detailed informa�tion regarding the documentation, optimization, and automation of organizational processes. With an increasing level of detail,such models become rapidly complex, thus hindering their correct comprehension (i.e., both, the efficiency and accuracy of understanding decrease). Furthermore, once a process model is created, the view on it and the respective level of detail remains rigid for all stakeholders. However, a process model may contain information, which is less relevant for certain stakeholders (e.g.,domain experts). Consequently, the comprehension of process models becomes more difficult, as all information in a model needs to be read. Existing modeling systems do not offer the functionality to dynamically change the level of detail of a process model according to the stakeholders’ preferences. To address this issue, the work at hand presents the Dynamic Visualization of Process Models (DyVProMo), a lightweight web-based tool that enables the dynamic visualization of information in process models expressed in terms of the Business Process Model and Notation 2.0

In defence of sandcastles : research thinking through visualization in DH

Although recent research acknowledges the potential of visualization methods in DH, the predominant terminology used to describe visualizations (prototypes, tools) narrowly focuses on their use as a means to an end and, more importantly, as an instrument in the service of humanities research. While acknowledging the broad range of possible approaches to visualization, we introduce the metaphor of the sandcastle to highlight visualization as a research process in its own right. We argue that building visualization sandcastles provides a holistic approach to interdisciplinary knowledge generation that embraces visualization as (1) a dynamic interdisciplinary process where speculation and re-interpretation advance knowledge in all disciplines involved, (2) a mediator of ideas and theories within and across disciplines and (3) an aesthetic provocation to elicit critical insights, interpretation, speculation and discussions within and beyond scholarly audiences. We illustrate our argument based on our own research of an exceptional literary collection.Postprin
