  1. IT’S ALIVE: DYNAMIC VISUALIZATION IN MATHEMATICS AND SCIENCE Scott A. Sinex & Barbara A. Gage Department of Physical Sciences Prince George’s Community College Presented at MICCA 2002: Technology, the Classroom, and You Baltimore, MD, 19-20 March 2002

  2. The Advantages of Technology a tool to enhance guided-inquiry instruction • Fast manipulation of large data sets • For graphical presentation: static to dynamic (mathematical models and simulations) • Leaving flatland: 2D to 3D with movement • Abstract concepts illustrated – microscopic nature of matter

  3. Meeting National Standards • American Mathematical Association for Two-Year Colleges (AMATYC) • National Council of Teachers of Mathematics (NCTM) • NSF’s Shaping the Future • National Science Education Standards • College Pathways to the Science Education Standards (NSTA) • National Educational Technology Standards (NETS)

  4. Dynamic Visualization Modified from Barry Adams, Apple Computer

  5. The tools we use • TI-83 graphing calculator – data analysis • Excel – data analysis and interactive spreadsheets • STELLA modeling software - simulations • Chime – molecular structure rendering software (freeware) • Spartan – to produce animations of molecules • Internet – data source, Java simulations • NetLogo (StarLogo T) – simulations of collections of particles (freeware)

  6. Why do we do this? • To get students actively engaged in the learning process • To explore further possibilities with models and simulations • To investigate at the conceptual level

  7. Some examples of what we do

  8. Support Resources & Data Downloads of freeware and pdf handouts for software PGCC Physical Sciences Dept.

  9. Interactive Excel Spreadsheets Interactive Curves Weak Acid Behavior Gas Velocity Distribution

  10. STELLA Models and Simulations To get STELLA at High Performance Systems- http://www.hps-inc.com Maryland Virtual High School CoreModels Program Dissolved Oxygen Model and Simulation (Use IE to download)

  11. Chime & Molecules To get Chime:http://www.mdli.com Molecules in Motion Structure and Bonding The chemists have left flatland! Browser plug-in and allows for interaction

  12. Spartan Computational chemistry software Rotation of Biphenyl Molecule and its relative energy Big movie file –slow to load Expensive software – faculty using as a tool in class and to produce animations as movies

  13. Internet Simulations NCTM Illuminations Website Ocean Dive Simulation http://www.illuminations.nctm.org/imath/912/Light/student/simdive.html

  14. NetLogo Simulations To get Netlogo- http://www.ccl.sesp.northwestern.edu/netlogo/ Gas Particles Model

  15. How has our classroom changed? • More use of Internet and STELLA simulations in lecture/discussion • More class time spent in the computer lab • More out-of-class projects that involve modeling data • Assessment of understanding rather than just regurgitation or algorithm application • More integration of mathematics

  16. How have our students changed? • Ask more involved questions and are more willing to participate • Are more comfortable using technology • Handle more involved assessments and projects successfully
