•   Sample Question Stem 6
•   Questions with key words
an "identify one" question, students will be allowed 1 minute to write
the key words.

-a "describe two" or "explain two" question looking for a description
and example, students will be allowed 2-3 minutes to organize.

- a "discuss three" question which also requires evaluation,
students will be allowed 10 minutes to organize.

We will try one question with you organizing your answers, but not
writing out the answers. Then we will discuss that question. If time
allows we will try a second question to see if your approach
improves.

The strategy is intended to stop you from just racing ahead and
writing without organizing your responses.
