A small class of functions is described that easily lend themselves to two-dimensional and three-dimensional visualizations at the basic calculus level. The intended audience is those educators involved in the instruction of elementary calculus. This note is an educational piece that begins with the question: "What happens if a function defined on…

These proceedings contain the papers of the International Conference on Mobile Learning 2013, which was organised by the International Association for Development of the Information Society, in Lisbon, Portugal, March 14-16, 2013. The Mobile Learning 2013 International Conference seeks to provide a forum for the presentation and discussion of…

This study assessed the effectiveness of computer-based biomolecular visualization activities on the development of high school biology students' representational competence as a means of understanding and visualizing protein structure/function relationships. Also assessed were students' attitudes toward these activities. Sixty-nine students…

Geographic information systems (GIS) are computer-based tools for geographic data analysis and spatial visualization. They have become one of the information and communications technologies for education at all levels. This article reviews the current status of GIS in schools, analyzes the requirements of a GIS-based learning environment from…

Mastering stress management techniques can help college developmental class educators protect themselves from burnout. These techniques can also be taught to students in developmental classes to enable them to maximize the benefits from these classes. This paper outlines the causes of stress, identifies stressors, describes responses to stress,…

This paper describes a faculty resource team in the Bradley University (Illinois) Department of Industrial Engineering that works with student project teams in an effort to improve their visualization and oral presentation skills. Students use state of the art technology to develop and display their visuals. In addition to technology, students are…

A practicum used a new learning tool to enhance long-term retention of new vocabulary. Sixteen seventh-graders in Language Arts, who had a long-term retention mean score of approximately 40% of newly learned vocabulary, increased their long-term retention of new vocabulary by 25% (a new mean of 65% of new vocabulary). Additional objectives…

High-level visual processes make use of stored information, and are invoked during object identification, navigation, tracking, and visual mental imagery. The work presented in this document has resulted in a theory of the component "processing subsystems" used in high-level vision. This theory was developed by considering…

Describes a demonstration designed to teach chemistry definitions. Important chemical terms which specifically related to the demonstration were defined on handouts and distributed to the students for reference during the demonstration. (MLH)

Educators are beginning to call attention to the failure to integrate right-brain, intuitive, holistic, visual processes into the curriculum. Approaches to right-brain education have characteristically called for the use of slow music, visual imagery, and relaxation techniques. Suggested principles for teaching basic skills include the facts that…

This study examines the Wheatley Cube as a measure of spatial/visualization ability. The Wheatley Cube is a computer managed task which requires the subject to visualize a three-dimensional workspace and to find an invisible dot located within this space. Thirty-three undergraduate students were administered four tests of spatial/imaginal ability…

This series of activities on spatial relationships was designed to help users acquire the skills of spatial visualization and orientation and to improve their effectiveness in applying those skills. The series contains an introduction to spatial orientation with several self-directed activities to help improve that skill. It also contains seven…

Large-sample item response data for the 10-item Paper Folding worksample 622 (N=2,749) and for five new experimental paper folding items (N=2,514) are analyzed with the logistic item response model and with full-information item factor analysis. The main results of the unidimensional analysis are that: (1) item discrimination is heterogeneous, so…

The report addresses the question of the structure of cognitive abilities, i.e., how many different abilities should be identified and the relations between abilities. Models suggested by Spearman, Thurstone, Guilford, Vernon, Cattell-Horn and others are reviewed. By combining features of the Vernon and Cattell-Horn models it is possible to…
