slide6

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
slide7

E-Book Chemistry Textbook

  • Chemistry: The Central Science 8th Ed.
  • Prentice-Hall Publishers
  • HTML format – entirely editable
slide8

E-Book Chemistry Textbook

  • Fully illustrated
  • Recently added problems, appendices, links
  • Access to Prentice-Hall Web site
slide9

SWATT: Student Response System

  • Interactive classroom questioning
  • Completely Web-based system
  • Student feedback is anonymous
  • Data are available for later analysis
slide10

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
slide11

SWATT: Interfaces Under Development

Numeric Response

Graphic Response

Confidence Response

slide13

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.

slide19

Pocket Hyperchem from Hypercube

  • Pen-based interface
  • MM+ and Semi-Empirical Calculations
  • Standard functions for general, inorganic, and organic chemistry
slide20

Bond angle calculation

General Chemistry

  • View and rotate molecules (pre-built)
  • Measure bond angles and bond lengths
  • View molecules in different renderings
slide22

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

slide25
