Refines the basic entity model of information theory and extends it to analyze mathematically the physical symbol transformation characteristics, as well as energy-matter and cognition phenomena occurring in the human mind. Reviews existing theories; examines physical symbol subsystem, cognitive perspective, energy-matter subsystem; and discusses…

Focuses on use of computer-drawn faces to explore visualization in learning and for presenting multivariate data. Prior and new research are reviewed and future applications are discussed. "Autocorrelation-face," a graphics representation created from mathematical analysis of voice input, and its potential as a learning aid for the deaf are…

According to Alfred North Whitehead, education precedes through three stages as it develops students' minds: (1) romantic; (2) precision; and (3) generalization. These stages are related to Whitehead's ideas about prehension and symbolic reference. Educational practices should strike a balance between the stages to encourage learning. (PP)
