Introduction
University education should be broadly based. Appreciation of science is important to the
general education of non-science majors.

Personal Response System (PRS) To involve students in active thinking To reinforce learning by an immediate review of
learned concepts To expose students to applications of learned
concepts in different contexts To maintain steady class attendance To clarify common misconceptions, especially
effective when a significant fraction of students was revealed to answer wrong
To assist the instructor in understanding the progress and misconceptions of students
To involve students in active discussionsThe last 3 points are illustrated in the following

PRS Question 11The escape velocity from the Earth is 11 km/s. If a satellite is launched from a space shuttle at a velocity of 9 km/s. The orbit of the satellite is1) a circle 2) a parabola 3) a hyperbola4) an ellipse with the space shuttle nearest to the Earth5) an ellipse with the space shuttle furthest from the Earth
Correct answer: 4)Majority answer: 5)
Note: The students may give the wrong answer in words even when they know the correct orbit in the figure (if they do not understand the launching operation of the space shuttle).

PRS Question 11 (rephrased)The escape velocity from the Earth is 11 km/s. If a satellite is launched at a velocity of 9 km/s from a space shuttle at point P, the orbit of the satellite is1) a circle 2) a parabola 3) a hyperbola4) an ellipse with the point P nearest to the Earth5) an ellipse with the point P furthest from the Earth

Clarification
1)
2)
3)
4)
5)
Many students knew that the correct answer is the orbit labeled 4) in the figure, but they gave 5) as their choice.
The misunderstanding probably comes from: The satellite is moving on the orbit, but the space shuttle is simply
the launcher in this problem. It does not follow the orbit after it has launched the satellite.
Some students thought that choice 5) is stating that the average distance of the orbit is furthest from the Earth, so they chose 5). In fact, the true meaning of this choice is: when the satellite moves along this orbit, it becomes furthest from the Earth at point P.

Conclusion• Activity-based learning can be implemented in
general education classes of large size.• The introduction of multiple modes of activities
makes the course interesting.• Nevertheless, the support of quality and
motivated manpower is an important factor.
