Topological data analysis (TDA) is a collection of powerful tools that can quantify shape and structure in data in order to answer questions from the data's domain. This is done by representing some aspect of the structure of the data in a simplified topological signature. In this article, we introduce two of the most commonly used topological…

This paper provides a tutorial on epistemic network analysis (ENA), a novel method for identifying and quantifying connections among elements in coded data and representing them in dynamic network models. Such models illustrate the structure of connections and measure the strength of association among elements in a network, and they quantify…

The purpose of this document is to recommend data visualization practices that will help education agencies communicate data meaning in visual formats that are accessible, accurate, and actionable for a wide range of education stakeholders. Although this resource is designed for staff in education agencies, many of the visualization principles…

Campaign finance might seem like the exclusive province of political reporters, but there are many good reasons why authors should be paying attention--both in races for education positions and in other key races at the local, state, and federal levels with implications for education. Basic math is a necessary skill and familiarity with a…

Students have experiences, during the school year, which enrich their understanding and knowledge of each other. Activities are described to enhance students' abilities to recognize and recall and to provide enjoyable, meaningful memories for students. (CB)

Describes visualization methods used to design projects intended to improve the quality of life in developing countries, but which are also applicable to group problem-solving situations. Details main stages of a case study. Demonstrates that the techniques improve the efficiency and effectiveness of the problem-solving process and the quality of…

"Mental modeling" refers to a student's ability to visualize or comprehend the information research process. This article reviews 50 years of changing conceptions of how we learn: behaviorist, cognitivist, and constructivist perspective; describes the application of three "mental models" to interactive technology; and discusses…

Demonstrates the use of scientific visualization, a computer graphics technology developed to extend the use of our visual system to contexts and problem-solving situations where sight itself is not directly possible or in which normal vision fails to provide adequate opportunity for analysis.

This article describes a process for increasing the quality of students' thinking through alternating from a quiet intuitive state to rational logical processing. The article provides specific teaching suggestions using guided imagery for students in grades K-2, grades 3-4, and grades 5 through college. (DB)

Hypermedia computing now makes it possible to integrate media into interactive programs with the potential to expand the use of visualization in science, art, and other professional disciplines. After an overview of some visualization issues in hypermedia, a research project called "HyperGlyphs" at Rensselaer Polytechnic Institute in…
