My Life at Renda
I learned very quickly that being a teaching assistant (TA) at the University of Iowa would be different from being a teacher at Renmin University.
________ (46) Eyes staring, mouths open, students examined my big nose, while I was writing my name on the blackboard.
At Iowa, when my first classes began, half of my students still hadn't arrived. When everyone finally found a seat, ringing cell-phones and loud yawns (哈欠) interrupted my opening remarks. It is not that American students were disrespectful. ________ (47) They were, however, far more skeptical than the students I had at Renda. The truth is I couldn't fault them for their skepticism. Under-graduates at large US universities - especially freshmen and sophomores - often have several classes a semester handled by TAs. In some cases, the TA sets the course content. ________ (48) Most have good intentions, but very few are as effective as professors.
Every teacher has to confront obstacles to learning - no matter what the culture. Students who talk during lectures, students who cheat, students who question the grade they get for a paper or project - dealing with these is all part of the job. ________ (49)
The difference, I think, is that in the US I had to swallow more of my pride. ________ (50)
I had a responsibility to teach them, of course, but I had to do so indirectly -as a guide who himself had a few things to learn from the students.
A In my students' minds, I had little to offer them, except perhaps some sample questions for the mid-term exam.
B In others, the TA works as a grader and discussion leader
C I encountered these in China, and I faced them in the US
D On the other hand, being taught by a graduate student is not necessarily bad.
E Most were polite, or at least, indifferent
F Back at Renda, I had walked into my first classes feeling like a celebrity
