What prevents TA's from teaching more than 1 or 2 discussion sections? If each of them taught 2~3 discussions, wouldn't everyone be happier? As students, it would be nice to know how the TA hours are managed. TA's earn a lot of money for teaching. Does a 20-hr TA do 2 hours of discussion, 1 hour of office hour, 1 hour of discussion prep, 1 hour of making homework, etc? How does it add up to 20 hours? Do they have to redesign the entire class and grade homework problems? If necessary, can they take one more hour of discussion from one of the other responsibilities? It would be great if the teaching staff is clearer and more open about this.
