If one day I win the lottery, I will probably do the same as I do today, since I love what I do. Except one thing: I will not grade exams. I only do it for the money. The rest I do for love.
The main reason I hate grading is that I get stressed trying to be fair, and give the same grade to equivalent answers. There are some strategies to achieve a fair evaluation.
- I evaluate each question independently. I do not evaluate person by person, but by set of answers, one set for each question. That way I can see the full picture and compare answers.
- When I read the set of answers, I do not know the name of the person I’m grading. So I cannot be biased.
- When evaluating a set of answers, I read the first one on good mood but I get more and more unhappy at the end. So the first answer of each set may get a better grade than the last one. To avoid this, I start grading sometimes at the end and go backwards, and sometimes I start in the middle.
To be honest, bad English affects me negatively, so good answers seem not-so-good. In general, if an answer is correct but not clearly explained, the grade is 99.
The preliminary grades can be seen at the course’s Google Sheet. You can see each question set here:
- 1. Taxon
- 2. Entrez query
- 3. Algorithm v/s Heuristics
- 4. How BLAST works?
- 5. Existence/extension?
- 6. Word Size
- 7. Average Nucleotide Identity
- 8. Looking for a professor
I wrote my comments in boldface.
Please check your grades and let me know if I made any mistake. Send me an email before next week. I will wait for your comments until the last minute when I have to publish official answers.
