There are few things as demotivating as discovering that in the end, in spite of (or maybe thanks to) all your efforts, your students learned absolutely nothing. Some of mine, apparently horrified by the exam study guide I presented them with, sent me a list of their own questions. That surprised me a bit but hey, sure, why not. And so, I have incorporated some of these questions into the exam, in a hope that this class at least would know some of the correct answers. Naturally, I was wrong.
Here’s an illustration.
The following three questions refer to the figure below.
Easy peasy, even for those who were absent or asleep 90% of the time. Right?
- Identify the cells A, B and D. What is the name of the process C? (4 points)
- If the cell A has n chromosomes, the cell B has chromosomes and the cell D has chromosomes (2 points).
- Both cells A and B are collectively known as .
And here are some unexpected answers, from three different students.
Althought it is not in my job description, I did that search and should say that the (Mandarin) Chinese terms are correct. Except the symbol ⭗ is not even Chinese (it’s just this student’s doodle of cell D), so it doesn’t count.
- Identify the cells A, B and D. What is the name of the process C? (4 points) *
* I'm gonna to write chinese, because I don't how to write in English, you can search internet
- Luan Zi
- Jing Zi
- Shou Jing
I can’t say it is wrong. Just a bit too generic for my liking. Ditto this:
- If the cell A has n chromosomes, the cell B has r chromosomes and the cell D has m chromosomes (2 points).
Here’s another one. I lifted this question from the textbook, but you don’t really need to know anything to solve the problem. Or so I thought.
- Both cells A and B are collectively known as cells .
- It takes just 1 minute for a bacterium to add 30 000 nucleotides to one DNA strand undergoing replication. The rate of replication in this bacterium is 5 000 nucleotides per second.* I don't have a calculator to determine this.
