Science and mathematics educators are expected to use existing educational technologies effectively and to keep informed about emerging technologies that might become important educational tools in the not-so-distant future. This monograph offers some help in that regard by highlighting a number of existing and emerging educational technologies. Chapters are: (1) "The Power of Visualization: The Impact of Graphing Technology on the Secondary Mathematics Curriculum," L. E. Yunker; (2) "Using Graphing Calculators to Teach High School Mathematics," L. Kaber & K. Longhart; (3) "Advanced Technologies as Educational Tools in Science: Concepts, Applications, and Issues," D. D. Kumar, P. J. Smith, S. L. Helgeson, & A. L. White; (4) "Videodisc Technology: Applications for Science Teaching," D. R. Lavoie; (5) "Computer Visualization: New Window on Mathematics," D. A. Thomas & M. Mitchell; (6) "Visualizing Computer Science," R. J. Ross; (7) "Getting Started With Supercomputing: An Approach for High School Students," D. W. Hyatt; (8) "Scientific Visualization in Chemistry, Better Living through Chemistry, Better Chemistry through Pictures: Scientific Visualization for Secondary Chemistry Students," R. R. Gotwals, Jr.; (9) "The National Education Supercomputer Program," R. Enderton & B. Lindow; (10) "New Mexico High School Supercomputing Challenge," M. S. Foster; (11) "Sharing Multiple Complementary Representations in the Teaching of Science," N. H. Sabelli & I. S. Livshits; (12) "Education and Collaboration in an Evolving Digital Culture," D. J.
