Three years ago, Eduardo Vianna, a professor at LaGuardia Community College in Queens, had a student who passed an entire semester without speaking in class. Like many others, the student, Mike Rifino, had come to LaGuardia requiring remedial instruction.

But the following semester Mr. Rifino turned up in Dr. Vianna’s developmental psychology course. This time he took a seat closer to the front of the room. Taking that as a positive sign, Dr. Vianna asked him to join a weekly discussion group for students who might want to talk about big ideas in economics, education and politics, subjects that might cultivate a sense of intellectual curiosity and self-understanding among students whose backgrounds typically left them lacking in either.
