For many graduate teaching assistants, the task of planning, organizing, mo
tivating, and controlling classroom environments can be overwhelming. Empir
ical research pertaining to major classroom management problems experienced
by TAs is scarce. This article is a report of a survey study regarding TA
classroom management at a large, land-grant Research 1 University. The stud
y provides specific information about TAs' perceptions of classroom managem
ent experiences and concerns based on TA type, gender, teaching experience,
and academic discipline. The results of the study indicate that internatio
nal and U.S. TAs experienced many common problems, but each of the two type
s of TAs also had unique problems. More U.S, TAs than international TAs rep
orted experiencing classroom management problems. The years of TA teaching
experience were significantly related to the number of classroom management
problems and concerns TAs reported. Regression analysis revealed that TA t
ype, teaching experience, and academic discipline, but not gender, were sig
nificant predictors of classroom problems and concerns. Discussion of the r
esults, implications, and suggestions for further research are included.
