My school splits our semesters in half. We just finished our first half and three of the instructors are moving on to different courses for the second half. I'm in one of the groups with an instructor that is moving on. Another group purchased a $150 gift certificate for their instructor. We went to lunch with our instructor yesterday but did not give her a gift. I wrote her out a thank you card but it turns out I was the only one that did. Now my group wants to get her a gift. Most of the group thinks it a good idea but a few of us don't. It seems inappropriate to spend that much on a gift for an instructor knowing we will have that instructor again in a year. I purposely waited to give her my thank you card until after my evaluation so it didn't look like I was trying to kiss butt or influence my eval. I understand giving a gift to say we appreciate the your time and support but I think $150 is too much for a 9 week class. What do guys think?
