Concept Mapping, Mind Mapping and Argument Mapping: What Are the Differences and Do They Matter?
Concept Mapping, Mind Mapping and Argument Mapping: What are the Differences and Do They Matter? W. Martin Davies The University of Melbourne, Australia [email protected] Abstract: In recent years, academics and educators have begun to use software mapping tools for a number of education-related purposes. Typically, the tools are used to help impart critical and analytical skills to students, to enable students to see relationships between concepts, and also as a method of assessment. The common feature of all these tools is the use of diagrammatic relationships of various kinds in preference to written or verbal descriptions. Pictures and structured diagrams are thought to be more comprehensible than just words, and a clearer way to illustrate understanding of complex topics. Variants of these tools are available under different names: “concept mapping”, “mind mapping” and “argument mapping”. Sometimes these terms are used synonymously. However, as this paper will demonstrate, there are clear differences in each of these mapping tools. This paper offers an outline of the various types of tool available and their advantages and disadvantages. It argues that the choice of mapping tool largely depends on the purpose or aim for which the tool is used and that the tools may well be converging to offer educators as yet unrealised and potentially complementary functions. Keywords: Concept mapping, mind mapping, computer-aided argument mapping, critical thinking, argument, inference-making, knowledge mapping. 1. INTRODUCTION The era of computer-aided mapping tools is well and truly here. In the past five to ten years, a variety of software packages have been developed that enable the visual display of information, concepts and relations between ideas. -

Tile-Based Methods for Online Choropleth Mapping: a Scalability Evaluation by Myung-Hwa Hwang
Tile-based Methods for Online Choropleth Mapping: A Scalability Evaluation by Myung-Hwa Hwang A Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy Approved September 2013 by the Graduate Supervisory Committee: Luc Anselin, Chair Sergio J. Rey Elizabeth A. Wentz ARIZONA STATE UNIVERSITY December 2013 ABSTRACT Choropleth maps are a common form of online cartographic visualization. They reveal patterns in spatial distributions of a variable by associating colors with data values measured at areal units. Although this capability of pattern revelation has popularized the use of choropleth maps, existing methods for their online delivery are limited in supporting dynamic map generation from large areal data. This limitation has become increasingly problematic in online choropleth mapping as access to small area statistics, such as high- resolution census data and real-time aggregates of geospatial data streams, has never been easier due to advances in geospatial web technologies. The current literature shows that the challenge of large areal data can be mitigated through tiled maps where pre-processed map data are hierarchically partitioned into tiny rectangular images or map chunks for ef- ficient data transmission. Various approaches have emerged lately to enable this tile-based choropleth mapping, yet little empirical evidence exists on their ability to handle spatial data with large numbers of areal units, thus complicating technical decision making in the development of online choropleth mapping applications. To fill this knowledge gap, this dissertation study conducts a scalability evaluation of three tile-based methods discussed in the literature: raster, scalable vector graphics (SVG), and HTML5 Canvas. -
Visualization Rhetoric: Framing Effects in Narrative Visualization
IEEE TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS, VOL. 17, NO. 12, DECEMBER 2011 2231 Visualization Rhetoric: Framing Effects in Narrative Visualization Jessica Hullman, Student Member, IEEE, and Nicholas Diakopoulos, Member, IEEE Abstract—Narrative visualizations combine conventions of communicative and exploratory information visualization to convey an intended story. We demonstrate visualization rhetoric as an analytical framework for understanding how design techniques that prioritize particular interpretations in visualizations that “tell a story” can significantly affect end-user interpretation. We draw a parallel between narrative visualization interpretation and evidence from framing studies in political messaging, decision-making, and literary studies. Devices for understanding the rhetorical nature of narrative information visualizations are presented, informed by the rigorous application of concepts from critical theory, semiotics, journalism, and political theory. We draw attention to how design tactics represent additions or omissions of information at various levels—the data, visual representation, textual annotations, and interactivity—and how visualizations denote and connote phenomena with reference to unstated viewing conventions and codes. Classes of rhetorical techniques identified via a systematic analysis of recent narrative visualizations are presented, and characterized according to their rhetorical contribution to the visualization. We describe how designers and researchers can benefit from the potentially -
Explicit Structure in Print and On-Screen Documents
TECHNICAL COMMUNICATION QUARTERLY, 14(1), 9–30 Copyright © 2005, Lawrence Erlbaum Associates, Inc. Explicit Structure in Print and On-Screen Documents David K. Farkas University of Washington The structure of print and on-screen documents is made explicit through headings and links. Three important concepts for understanding explicit structure are (1) the display-unit properties of each document medium, (2) the flexible relationship be- tween explicit and implicit structure, and (3) the distinction between populated and unpopulated locations in a hierarchy. These concepts help us better understand stan- dard print documents, structured writing, websites, help systems, and PowerPoint, as well as the potential effects of content management systems on how documents are created. Contemporary rhetoricians, including those who study technical communication, are most often concerned with documents in their social contexts, as dialogues with readers and dialogues among those producing the document (Bazerman and Paradis; Blakeslee). We mustDo not, however,Not forget Copy to look closely at the document itself, for reading and document use are ultimately about the close encounter be- tween people and the document features they look at and click. Among the most important document features are those that make explicit the structure of docu- ments. The primary means to make structure explicit is through headings and links. In this article I identify and explain three concepts that further our understand- ing of explicit structure and can contribute to the design of more effective docu- ments: (1) the display unit and display-unit properties, (2) the flexible relationship between explicit and implicit structure, and (3) the distinction between populated and unpopulated locations in a hierarchy. -

James Thurber (1961) This white paper defines information mapping and reviews a range of examples. The focus is on two-dimensional interactive information maps that can be used to summarise large volumes of textual information, provide interfaces to browse the whole corpus and retrieve particular documents of interest. Information maps are being developed to tackle the modern-day challenges of information overload – too much, too fast and too unmitigated 1. The average person sitting at a networked PC has access to a huge (and hugely growing) array of textual data that can be utilised as a vital information resource in helping to make decisions. The data are in the form of documents on their own hard disk, messages pouring in through email and IM, from databases on intranets and digital libraries on the Internet and, of course, there is the expanse of the World-Wide Web, encompassing several billion static pages and an unknown volume of dynamically generated content. -

LOD Map - a Visual Interface for Navigating Multiresolution Volume Visualization
IEEE TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS, VOL. 12, NO. 5, SEPTEMBER/OCTOBER 2006 LOD Map - A Visual Interface for Navigating Multiresolution Volume Visualization Chaoli Wang, Student Member, IEEE, and Han-Wei Shen Abstract—In multiresolution volume visualization, a visual representation of level-of-detail (LOD) quality is important for us to exam- ine, compare, and validate different LOD selection algorithms. While traditional methods rely on ultimate images for quality measure- ment, we introduce the LOD map - an alternative representation of LOD quality and a visual interface for navigating multiresolution data exploration. Our measure for LOD quality is based on the formulation of entropy from information theory. The measure takes into account the distortion and contribution of multiresolution data blocks. A LOD map is generated through the mapping of key LOD ingredients to a treemap representation. The ordered treemap layout is used for relative stable update of the LOD map when the view or LOD changes. This visual interface not only indicates the quality of LODs in an intuitive way, but also provides immediate suggestions for possible LOD improvement through visually-striking features. It also allows us to compare different views and perform rendering budget control. A set of interactive techniques is proposed to make the LOD adjustment a simple and easy task. We demonstrate the effectiveness and efficiency of our approach on large scientific and medical data sets. Index Terms—LOD map, knowledge representation, perceptual reasoning, multiresolution rendering, large volume visualization.
