Dear TBL list users:
I've been using some aspects of TBL in an introductory level (200)
environmental science course for almost 2 years. For the first time
I now have a Tuesday-Thursday time slot and am using more in class team
exercises. Today, we discussed 2 questions I made up based on
material from the chapter on evolution and biodiversity. I thought
they were pdg questions, but some of the class (and me a bit) were
frustrated by the discussion and the inability of me (and groups that
agreed with me) to convince a couple of "hold-out" groups what
the best answer is.
If ensuring discussion warrants it, I'll identify the choices involved in
the gridlock. But, I'd like to start by just repeating the
questions and ask for opinions, feedback, etc. about the questions - what
am I missing??? BTW, there are 6 groups - 4 of 5 people and 2 of
6.
1. Which is the best symbol or exemplification of human evolutionary
success?
A. Apple
B. Infant
C. An elderly person
D. Hammer
2. Which is the best symbol or exemplification of cockroach evolutionary
success?
A. Exoskeleton
B. Young cockroaches
C. Elderly cockroaches
D. The cockroach leg (note: from the course text: the
cockroach leg is highly sensitive to vibration, enabling them to escape
under the baseboard before we're able to squash them
underfoot!)
