Laboratory Experiments in the Lecture Hall



I would appreciate comments from this list (pro and con) concerning your
experiences in using data logging demonstrations in the classroom. An
example which seems to work with adequate preparation is the demonstration:
1D15.10,
Velocity, Position, and Acceleration: Ultrasonic Detector and Students.

Which have worked, an which have not worked and why?

How much time can be committed in a given lecture?

How much of the course can be addressed via this mechanism?

Where do you draw the line between the laboratory, which the students
perform, and the laboratory/lecture, which you perform?

How much faculty preparation time is involved (a) initially, (b)
immediately prior to the classroom presentation?

Do students respond favorably to laboratory data taking in the classroom?
Is their reaction over-ridden by policy?

At what level of students/courses does this technique work?

What are the pedagogical strengths/weaknesses of such an approach?

I APOLOGIZE FOR THE MULTIPLE LIST POSTING.

Thank you, Karl
