The paper examines the definition and concept of Electronic navigation (e-navigation), Electronic Chart Systems (ECS) and Electronic Chart and Display Information System (ECDIS). In paper are provided compare of positive and negative aspects for alternative e-navigation platform "BalticWeb", developed in "EfficienSea2" project…

This theoretical paper describes how Community-based Mathematical Modeling can advance equity and cultivate civic empathy in elementary school settings. We provide a framework for community-based mathematical modeling instruction consisting of five goals: facilitating connections, fostering engagement, promoting rigor, cultivating civic empathy,…

The field of education is undergoing fundamental change with the growing use of data. Fine-scale data collection at the item-response level is now possible. Xerox has developed a system that bridges the paper-to-digital divide by providing the well-established and easy-to-use paper interface to students, but digitizes the responses for scoring,…

This paper proposes an extension to mobile augmented reality (MAR) environments--the addition of data charts to the more usual text, image and video components. To this purpose, we have designed a client-server architecture including the main necessary modules and services to provide an Information Visualization MAR experience. The server side…

Traditional data mining techniques have been extensively applied to find interesting patterns, build descriptive and predictive models from large volumes of data accumulated through the use of different information systems. The results of data mining can be used for getting a better understanding of the underlying educational processes, for…

This paper reports on applications of quality tools, developed for industrial settings, to educational management and instruction at three technical education centers. The necessary data were collected by the centers as they prepared for registration to the International Standards Organization Quality Assurance Standards. Application was made of…

The aim of good data graphics is to display data accurately and clearly. This definition is used as a point of departure for developing 12 rules of bad data display: (1) show as little data as possible (minimize the data density); (2) hide what data you do show (minimize the data-ink ratio); (3) ignore the visual metaphor altogether; (4) only…

Discusses the use of quantitative graphs in newspapers and identifies 10 common problems to avoid in the use of informational graphics, including (1) the tilted graph; (2) the stacked graph; (3) the convention-violating graph; (4) the unnecessarily three-dimensional graph; and (5) the overly complex graph. (MM)

Neither a review of the literature nor three data displays (showing career paths, general influence patterns, and predecessor and successor influence patterns) yield a generative or explanatory theory by which to understand data collected on the professional career paths of Alberta (Canada) educational administrators. The data came from a survey…

This paper is a brief report on the impact of school closings on purchasing departments. It opens with a discussion of the trend of declining enrollments in public schools nationwide. The paper notes, however, that demographers expect the total number of children to begin to rise slightly in the mid-80's. Closing schools now is not the answer, it…

A study, to support the need for exploratory research, was designed to elicit a description of the medical chart located in its setting--the chart was looked "through" as a tool (as a means to an end to effect particular medical goals) and looked "at" itself as technology. This could provide a way to understand the relationship…

Recent advances have been made in facilitating implementation of Ausubel's advance organizer strategy. One reason Ausubel's approach has not been widely adopted is its lack of specificity about how to relate what is to be learned to what has already been assimilated within the cognitive structure. The use of subsumptive sequencing, coordinate…

Introductory college level geography textbooks can be enhanced by using scatter diagrams and double criteria classifications, both of which reveal generalizations and specific facts about location. Scatter diagrams, a series of dots on a graph, illustrate relationships among phenomena that covary, e.g., national birth and infant mortality rates.…
