My school uses a team approach in new student orientation. We keep students together as departments/majors and walk them through stations throughout the school. The program chair ans full time instructors meet with groups of students in their respective programs to lay out expectations and supply students with academic advisors and contact information. The physically go to the library, registrar’s office, book store, etcetera and are introduced to all key areas of the school. They become familiar with the faces and names of administrators and teachers.
The basic procedure is to have a student ambassador chaperone groups of students around the school. The student ambassador is a member of the program that students will be entering. So students get to speak with one or more current students in their program.
