I use the very, very, very handy script from Tim Hunt: User role's report
You must also patch your system. but it is worth the effort, thanks Tim!

To make this report work, you need to make one very small change to one core file. In lib/weblib.php, in the function print_header, just after the line:
$meta .= "\n".require_js();
add the lines
$fnname = 'require_css';
if (function_exists($fnname)) {
$meta .= "\n".$fnname();
}
Why would you not just be able to go into 'Assign Roles' in the course, click on 'Teacher', and then remove the students that way?
Because that does not reset the roles in the table, ESPECIALLY when you create ADDITIONAL ROLES (a bug in 195?)

You're kidding me ... wow. So even if you remove the 'Teacher' role in the 'Assign Roles' view of the course, the student still keeps the teacher rights? 
No, I had an additional role parent. This became the default role in a course. removing that role only worked with the script.. so keep it in mind when normal removal does not work: this works always.
Great, thanks for the info! I just installed it on our dev server and seems like a great tool to have on hand. The 'latest version' didn't work so I tried the other one and it seemed to work OK. (we run 1.9.5 20090826)
Just out of curiosity, do you know of a way to CHANGE bulk role assignments as opposed to just removing them? (besides using a db query of course..)

Sorry, I do the database query..
I did what Susan suggested. Now I have to log in as one of the students to see what he can do.............
