Top: "In order to improve the quality of instruction at the college and university level, all faculty should be required to spend time working outside the academic world in professions relevant to the courses they teach."

Can working here refer to research? Umm.. I don't think the writer would intent to refer to "research". Because it's often necessary for faculty to do researches, in order to be more prominent and to get more valuable papers published.

No. Basically this is asking whether we should have teachers with "real-life" experience in the classroom.

e.g. Teachers of criminal justice courses should have work experience in the criminal justice system. Or journalism professors should have work experience as reporters or news editors.
Thank you for helping, Lielai, thank you. I am writing it.

By the way, I couldn't come up a chinese name that matches Pinyinized "lielai". Is it your real name? hehe Guess not.
Students: We have free audio pronunciation exercises.
You're welcome, Jeff.

You can call me Julie. Julie is an English name, like Jeff.

My last name isn't Ju. I can tell you that much. Emotion: smile
Hehe. I thought "Ju" would be the surname "Zhu" in Chinese; then I took granted ...

But anyway, thank you for your time.
