  1. http://aa.uncwil.edu/numina Mathematics on Pocket PCsICTCM – 2002 Orlando, FL. Russ Herman, Mathematics and Statistics Gabriel G. Lugo, Mathematics and Statistics University of North Carolina at Wilmington

  2. Outline of Presentation • PPC History at UNCW • Handheld and Pocket PCs • Pocket PC Software for Science and Mathematics • Student Assessment with PPC • Student Response System • Future Developments If Pocket PCs are the next wave of the future, then can we do useful mathematics on them?

  3. PPC History at UNCW The Players Philosophy Funding

  4. Multi-disciplinary team - technology projects since 1990. Pocket PC History at UNCW • Funded by Pearson Education and UNCW -1999 to explore handheld computer technology for teaching science and mathematics.

  5. Pocket PC History • Initial work done with Hewlett-Packard Jornada 690 and 720 handheld computers • Wireless networks installed in the chemistry, math, and computer science buildings

  6. Numina II Project • Internal seed grant to study the use of the Pocket PC vs. the handheld PC. • Is it possible to do serious college-level work on PPC? • What additional hardware and software are needed to make the PPC a viable option for students and faculty?

  7. Handheld and Pocket PCs Models Handheld PC - HP 720 Pockect PC - HP 568 Wireless Networking Classroom Distribution

  10. Wireless Networks • 802.11b Standards-based network • 150’ range around access point (indoors) • 11 Mbps throughput • Network access from anywhere in the building

  11. Classroom Distribution • Pocket PCs are distributed to students in class • PPCs are stored on “charging” carts Pocket PCs Handheld PCs

  12. Software for Mathematics General Applications Calculators Graphing Utilities Symbolic Software Data Acquisition Other Applications

  13. MS Pocket Word • Reads and writes standard MSWord (.doc) documents • Will read and display sub/super-scripts but will not create them • No support for tables • No Equation Editor

  14. MS Pocket Excel • Reads and writes standard MSExcel (.xls) documents • Does not support graphing • Will not allow non-consecutivecolumn selection • No statistical routines

  15. MS Pocket Internet Explorer • Supports • standard HTML • JPEG and GIF • embedded Media Player • Flash 5 (on PPC) • Limited to No Support • Animated GIFs (none on PPC) • Java support (very limited)
