Geoscience after IT: Part J. Human requirements that shape the evolving geoscience information system

The geoscience record is constrained by the limitations of human thought and of the technology for handling information. IT can lead us away from the tyranny of older technology, but to find the right path, we need to understand our own limitations. Language, images, data and mathematical models, are tools for expressing and recording our ideas. Backed by intuition, they enable us to think in various modes, to build knowledge from information and create models as artificial views of a real world. Markup languages may accommodate more flexible and better connected records, and the object-oriented approach may help to match IT more closely to our thought processes

MatriksMovie: Building The Nation Character Through Movie-Based Realistic Mathematics Education

The root of RME is Hans Freudenthal’s interpretations, mathematics as human activity and mathematics must be connected to reality. This study developed a mathematics teaching and learning model that includes the characteristics of RME packaged in production and utilization of educational films in the learning process, it is called MATRiKSMovie Activity. Activity theory is based on Vygotsky's cultural-historical psychology and it focuses on understanding human activity and work practices. Practice of problem solving in real life can lead students to reflect, and build nation character. This research question are how to develop and implement a valid, practical and effective model of teaching and learning with movie based RME approach in Senior High Schools and its effect on students character and learning outcomes. Conclusion of this research are model of teaching and learning with movie based RME approach met the criteria of the content and construct validity, practicality, and effectiveness as it resulted in some positive impacts on the pupils at Grade 10 in Senior High Schools, mathematics learning with movie-based RME approach can serve to build student character as well as the civilization of the nation's dignity in order to educate the nation life, activities and process skills of students in mathematics learning with movie based RME approach has provided a positive impacts on the student learning outcomes (cognitive, affective, and psychomotor). Model of teaching and learning with Movie-based RME approach can be applied in learning mathematics and should be developed further by taking into account students' environment, conditions and facilities available. Humanistic mathematics learning should be developed to build the nation character. Keywords: MATRiKSMovie, Realistic Mathematics Education, Movie, the Nation Characte

Workshop on NASA workstation technology

RIACS hosted a workshop which was designed to foster communication among those people within NASA working on workstation related technology, to share technology, and to learn about new developments and futures in the larger university and industrial workstation communities. Herein, the workshop is documented along with its conclusions. It was learned that there is both a large amount of commonality of requirements and a wide variation in the modernness of in-use technology among the represented NASA centers

Visualizing the semantic content of large text databases using text maps

A methodology for generating text map representations of the semantic content of text databases is presented. Text maps provide a graphical metaphor for conceptualizing and visualizing the contents and data interrelationships of large text databases. Described are a set of experiments conducted against the TIPSTER corpora of Wall Street Journal articles. These experiments provide an introduction to current work in the representation and visualization of documents by way of their semantic content

From Models to Simulations

This book analyses the impact computerization has had on contemporary science and explains the origins, technical nature and epistemological consequences of the current decisive interplay between technology and science: an intertwining of formalism, computation, data acquisition, data and visualization and how these factors have led to the spread of simulation models since the 1950s. Using historical, comparative and interpretative case studies from a range of disciplines, with a particular emphasis on the case of plant studies, the author shows how and why computers, data treatment devices and programming languages have occasioned a gradual but irresistible and massive shift from mathematical models to computer simulations
