  2. Introduction to System • Applications • Web-based textbook • SWATT • Experimental results • Hyperchem • Digital Library

  3. Handheld Computers and Wireless Network • HP Jornada 720 handheld computers • WinCE Professional 2000 • Cisco Aironet 340 wireless network products

  4. HP Jornada 720 Handheld Computers • StrongArm CPU: 206 MHz • 32 MB + 48 MB of RAM • WinCE (Word, Excel, PowerPoint, Explorer, Access) • Hyperchem, FTP

  5. Cisco 340 Wireless Network • 802.11b Standards-based network • 150’ range around access point (indoors) • 11 Mbps throughput • Wireless access throughout entire building

  6. Computer Distribution • Computers distributed in class from carts • 32 computers on each cart with power supplies • The contents of each cart can be distributed and returned in under 6 minutes

  7. E-Book Chemistry Textbook • Chemistry: The Central Science 8th Ed. • Prentice-Hall Publishers • HTML format – entirely editable

  8. E-Book Chemistry Textbook • Fully illustrated • Recently added problems, appendices, links • Access to Prentice-Hall Web site

  9. SWATT: Student Response System • Interactive classroom questioning • Completely Web-based system • Student feedback is anonymous • Data are available for later analysis

  10. SWATT: Student Response Pad • Student view is synchronized with classroom view through the Web-based database • IP address of Jornada is used to prevent multiple responses to the same question • Nearly 100% student participation

  11. SWATT: Interfaces Under Development Numeric Response Graphic Response Confidence Response

  12. Which one of the following statements about a chemical reaction at equilibrium is correct? • The concentrations of reactants and products are equal. • The rates of the forward and reverse reactions are equal. • No more reactants are converted to products. • d) The concentrations of reactants and products change with time.

  14. What is the half-life of the following first-order reaction? a) 2 s b) 10 s c) 5 s d) 20 s

  15. What is the half-life of the following first-order reaction? a) 2 s b) 10 s c) 5 s d) 20 s

  16. What is the value of the equilibrium constant (K) for this reaction? a) 9.0 b) 1.0 c) 0.90 d) 0.11

  17. What is the value of the equilibrium constant (K) for this reaction? a) 9.0 b) 1.0 c) 0.90 d) 0.11

  18. Pocket Hyperchem from Hypercube • Pen-based interface • MM+ and Semi-Empirical Calculations • Standard functions for general, inorganic, and organic chemistry

  19. Bond angle calculation General Chemistry • View and rotate molecules (pre-built) • Measure bond angles and bond lengths • View molecules in different renderings

  20. Exercise #1 Experimental group used Hyperchem to rotate molecules and measure bond angles

  21. Exercise #2 Control group used the Jornadas to view this as a Web form in color, but with no rotation capability

  22. Sample Quiz Questions

  23. VSEPR Questions

  24. VSEPR Questions Gas Law Questions

  25. Organic and Inorganic Chemistry • Build molecules • Optimize geometries • Explore properties of molecules

  26. Study the nature of the strain in methyl substituted cyclohexanes Organic Chemistry mono hexa

  27. Inorganic Chemistry • Generate the MO diagram for BF3 and study its Lewis acid-base chemistry

  28. Part of the NSDL initiative • Library resources are peer-reviewed • Ready to receive contributions • http://aa.uncwil.edu/dl
