Multimedia in the Classroom  Multimedia used in UNCW science and math lectures and labs for nearly 10 years  Student role is generally passive  Tests do not contain multimedia  Computers are not available for calculations and modeling in large classrooms

HP Jornada 690 H/PC  Full keyboard  VGA color graphics  32 MB internal  48 MB external  Audio and video  MS Pocket Office w/Internet Explorer

Wireless Ethernet Connectivity  b Standard-based wireless network  11 Mb/s throughput  150’ range around access point

e-Book Version of Textbook  Brown, LeMay, & Bursten / Prentice-Hall  Textbook in HTML  Editable  Graphics and equations

e-Book Version of Textbook  Illustration from e-Book  Access to Prentice-Hall textbook Web site

Pocket Version of Hyperchem  Pocket Hyperchem from Hypercube  Pen-based interface  Standard functions for general and organic chemistry

Statistical Applications  Commercial MS-DOS emulator is available  Allows legacy DOS applications to run on the Jornada

Distributing the Jornadas  32 computers and chargers on each cart  Computers can be distributed in 2 minutes and collected in 5 minutes

Classroom Use of System  Electronic whiteboard is used to present questions, choices, and results.  Each student has a Jornada so they can work individually or in groups.

Classroom Use of System Students become comfortable with the system in just a matter of minutes.

Equipment Security  Vernon radio frequency system  8.2 MHz transceiver  Single pedestal all-in-one design  6’ bipolar range

SWATT: Student Response Pad  Web-based student response system  Customizable student interface  Student role shifts from passive to active  Data stored in database Student View

SWATT: Student Response Pad  Response views controlled by instructor  Responses can be anonymous (or not)  Responses are available for analysis Class View for Multiple Choice

SWATT: Student Response Pad Where is Madrid?

SWATT Example 1 Which diagram shows the minimum amount of hydrogen needed to react with all the CO to produce CH 3 OH? *

SWATT Example 2 Which diagram is the correct representation of NaN 3 decomposing into elements at room temperature? *

SWATT Example 3 Which one of the following is the correct balanced equation for the decomposition of sodium azide? *

SWATT Example 4 Do you like working through problems using this format with the handheld computers (Y/N)?
