Education research: "clicker zombies"

With 16 clicker questions in a weekly, three hour evening lecture in introductory astronomy, students stay awake only enough to click in. With so many clicker questions interspersed throughout lecture (approximately 10 minutes per clicker question) with not enough student-student interaction, results in the above dramatization--many students with heads down, too exhausted to take notes, only rousing themselves to make the obligatory effort to click in (for participation credit).

Astronomy 10, Spring Semester 2008
Cuesta College, San Luis Obispo, CA

Astronomy 10 learning goal Q10.1

Students were asked the following clicker question (Classroom Performance System, einstruction.com) at the start of their learning cycle:

[0.3 points.] Why is entering the event horizon (the "Schwarzchild radius") surrounding a black hole considered a "point of no return?"
(A) All matter is crushed into nothingness.
(B) All matter is instantly converted into energy.
(C) The escape velocity is faster than the speed of light.
(D) Time runs backwards.

Correct answer: (C)

If students ask about what's inside the event horizon of a black hole, point out that they could certainly try to enter it and find out for themselves. However, in the very unlikely event that would be able to survive the journey, they would not be able to tell anyone in the outside universe about their discoveries, as nothing, not even light would be able to escape from within the event horizon. So they should bring a friend to share in the experience. Otherwise, it'd be lonely in there...

And yes, the expression on the middle kitten is priceless.

Physics 8A learning goal Q8.5

Whether or not the cats rebound from each other or not, momentum would still be conserved, provided that the collision was very brief, and/or that external impulses are negligible.

These cats were apparently posed and photographed from above while sleeping, and not actually photographed while in mid-collision.

Running down a wall does not necessarily mean gravity has been ignored...but nice try!
