Teaching Assistant Discussion Evaluation - Gene Duplication/Color Vision  

** We had charts availiable so they could tell if they were color blind.

Did the students enjoy this discussion / project?

1) Discussion was slow - maybe because it was the week following the test ???

2) I think students enjoyed the article.

3) Many of my students did not read the article.

What did the students learn from this discussion project?

1) One example of how gene duplication is important to evolution

2) Natural history - origin of color vision. Potential of gene duplication  - especially by unequal crossing over.


What did you like best about this week's discussion?

1) We had an opportunity to discuss the maintenance of color-blindness in humans as a result of mutation. This was the first time mutation was important for affecting gene frequencies.

2) The color blindness testing book was great!

3) I thought the article was easy and enjoyable to read, but not much to discuss.

What didn't you like?

1) I did most of the talking - there didn't seem to be much to discuss. Either they understood the article or they didn't.

2) I'm not sure how this topic fit in with the rest of the course . The concepts were not difficult. Time might have been better spent on aonther topic.

3) It seems like only two points are being made - gene duplications - it was difficult to structure an entire class around this. Much of this article was about mechanisms of color blindness.

In what ways can this exercise be improved?

1) Maybe we could discuss a review paper as well.
