Q/A pauses |
|
Breaks the monotony of a straight lecture. |
|
It helps to emphasize important points. |
|
It “shifts gears” and further captures students' attention. |
|
Participation |
|
Allows all students to participate. Not just the
dominant ones. |
|
Anonymous input. Helps monitor individual
participation without embarrassment. |
|

|
Consider the setup of a “walking dog”, which is
a spool wrapped around by a string. It has an inner radius a and outer
radius b. When the rope is pulled vertically, the spool rolls to the left. |
|
As the rope is pulled to the right, which
direction will the spool roll? |
|
Choices |
|
A
Rolling to the right |
|
B. Rolling to the left |
|

|
Pre-test on lesson: Interactive quiz session |
|
Interact with neighbors, full class
participation. |
|
Further capture class attention on the lesson: e.g.
Experiment |
|
The lesson: |
|
Linear motion: F=ma. |
|
Rotation: Rot-force = Rot-mass ´ Rot-acc |
|
Torque= I ´ angular acceleration |
|
Torque= force ´ level arm |
|
Choose
the pivot at the contact point. |
|
Digression:
à Choose
the pivot at the |
|
center. Which way will the spool roll? |
|
|
|
|
Prepared questions: Part of the lesson plan |
|
Extemporaneous questions |
|
Verbal, chalk board, overhead, power-point,
incorporate into cps system |
|
Initial resource: |
|
Questions is available on the web – IQ library |
|
Or make your own set of questions from old exams
or test bank. |

|
Phys 303L,
CC |
|
Bio 331L,
KS investigated the use of the system in small classroom teaching. |
|
Fall 2002: Wireless system will be available in
following CNS-Multimedia rooms: |
|
o GEA 105, PAI
2.48, 3.02, 4.42 |
|
o RLM: 4.102, 6.104
and WEL 3.502 |

class. |
|
There will be about one-hour wireless orientation
session for instructors and their TAs. |
|
Instructor’s

|
|
Student registration |
|
The
student needs register at the cps- website, for each of his/her class where
the wireless system is used. |
|
Student’s

|
CPS system returns a response number for
this student in the class. |
|
|
|
|

classrooms: |
|
GEA 105, PAI 2.48, 3.02, 4.42 |
|
RLM: 4.102, 6.104 and WEL 3.502 |
|
and
want to use the system, you may signup at

CNS-Dean’s office hopes that in the near future,
many instructors in our college who want to use this technology, will be
able to use it. |
|
The office needs faculty’s input to decide what subset
of CNS rooms should have this technology installed. |
|
If you
are interested in using this technology in your teaching in classroom which
does not have a wireless system, please contact: |
