Some classes will be only 5 people, others may be a hundred. The largest are about 250, but students rarely have more than 3 of these during their entire career at Hopkins. Professor Accessibility Hopkins prides itself on being an undergraduate, research university. The professors all teach. We don't have a separate research and teaching faculty.
All professors teach and all professors do research.
In most cases, these are one and the same, with professors teaching what they do research on. It provides for a hands on learning environment where students get to develop a strong faculty-student bond. Additionally, all professors at Hopkins hold office hours, but students are not restricted to office hours when they have questions. Typically, if a professor is not in his or her office, students will seek them out around campus - in their lab, in the coffee houses on campus, or at home. Professors are generally accessible to students, often giving out their email addresses and home phone numbers to students.
