I hate group projects and always have. I was REALLY lucky to have been grouped with very good people for my teaching this quarter (we were excellent and completely rocked our unit), but even though all the grad students are very smart in my program, there are some who I don't want to work with. Some people are FAR too pushy or too emotional and when shoved into a group together, this creates a ton of problems. One of my friends got put into a group like that and his group is doing horribly. I feel bad, because I know he's an excellent teacher, but he's not a confrontational guy and his group can't stop fighting with each other. (He also got thrown under the bus by a group member because she's terrified of our professor, which honestly I do not get.)
Also I was about to kill some people for a group presentation for putting off meeting for so long, but we cranked it out and did a great presentation, so I don't want to kill them anymore. But I sure as hell don't want to do that ever again. (We put an hour long presentation together in two days and one of the members didn't even contact anyone until the night before it was due, so we had to insert her into part of it, even though she did no work.)
I mean, I completely understand that working with other people is important, but doing it ALL THE TIME (like I have with one of my classes) is not cool. We're adults with different work schedules and heavy course loads and having to find the time between class, work, and actually doing homework to meet with people who also have these constraints and probably families, too, is just too much. I'm tired of group projects. I want to do stuff on my own. Also I hate that some of my classes are mixed with undergrads. Some of them are lazy or just don't care and I don't want to work with them, but sometimes I have to. Some of them are super cool, but most of them are not. (The undergrads are just getting a teaching license, which are dual or grad level courses they're taking for undergrad credit.)
