Less than 10 minutes had passed before Daniel Diermeier, Vanderbilt University’s chancellor, told hundreds of new students what the school would not do.

The university would not divest from Israel.

It would not banish provocative speakers.

It would not issue statements in support or condemnation of Israeli or Palestinian causes.

Before the hour was up on Monday, he added that Vanderbilt would not tolerate threats, harassment or protests “disrupting the learning environment.”

This month, Vanderbilt required all first-year undergraduate students to attend mandatory meetings about the university’s approach to free speech, with the hope that clear expectations — and explanations for them — would help administrators keep order after protests rocked American campuses toward the end of the last academic year.

“The chaos on campuses is because there’s lack of clarity on these principles,” Dr. Diermeier said in an interview.

There is no guarantee that the pre-emptive, plain-spoken meetings will work. Many student activists and professors at Vanderbilt have condemned the university’s rules as suppressing their speech, and even universities with histories of hard-nosed tactics have struggled with demonstrations.
