 e.g.
 The effect of resistor.
 The limitation of connection of CRO
The excel spreadsheet has three
usages
 1.As the demonstration of the various graph
in lecturing
 2.As a virtual experiment of AC in the
computer.
 3.As a tool of prediction before doing the
real experiment
 4.As a self learning or group learning tool
1. As a demonstration tool
 Use a large screen
 Copies of the graph should be available for
the student.
2. Virtual experiment
 1. The student previous in using excel is
different.
 2. Computer room and MMLC with teacher
control ( key board control)
 3. New teaching method ?
Please be prepared before using the
computer room and MMLC
3.A useful tool of Predicting the
