Some statistics on physics and astronomy degrees
The scientific environment for P&A SPIN-UP: site visits and survey What makes a department thrive? Take home lessons
Some Statistics 27-28% of high school students take physics.
The % is growing! 50:50 men/women!! 70-75% of US high school students go on to 2-
year, 4-year colleges and universities. BS degrees awarded in math, physical
science, engineering declined dramatically beginning in 1985.
The number of life science students going on for careers in basic research declined.

A Puzzle
Why and how did some physics departments increase the number of undergraduate majors during the 1990s while most experienced substantial declines?

“Thriving” Undergraduate Physics Programs
Produce > 4-5 times the national average of physics bachelor’s degrees (for their type of institution).
Actively engage students in the life of the department, including research.
Are viewed as excellent departments for both majors and non-majors.

What is a physics program?
•Recruitment, advising, mentoring students.•Engaging students in research.•Providing appropriate and excellent courses for
all students, not just majors.•Talking to and getting feedback from your students and to faculty in their home departments.•Building a sense of community among physics
students and faculty?•Informing students about and preparing them for
diverse careers.
What Makes an Undergraduate Physics Program
Thrive?
Strong and sustained departmental leadership Well-defined sense of mission Recruit and retain students
Challenging and supportive program Career information - alumni Introductory courses Prof. development and mentoring Multiple-tracks/options Research experiences – early and often
Emphasis on the entire program of the department, large fraction of the faculty engaged.
I was hired to do research. My evaluations are great – of
course my students are learning! “Reform” is just dumbing down the
curriculum. (see quote from Lloyd Taylor, 1938)
The Resistance
Some SPIN-UP Survey Results 500/759 physics departments graduate < 5 majors/year
54 Ph.D.-granting42 masters-granting394 bachelors-granting
The undergraduate program is remarkably “standard” across institutions.84% of the departments offer several alternative “tracks.” Some correlation (with exceptions) between recruitment, community-building, career and professional development and number of bachelors degrees awarded.60% report “significant” changes in curriculum over the last several years.
28 “Big Losers”tend to blame “external factors”
7 “Big Gainers”Recruitment, retention effortsReformed curricula and pedagogy, particularly at introductory levelMulti-track, flexible majors’ program

Take Home Messages
A physics program is more than the courses.
The department is the critical unit for change.
All reform is ultimately local. One size does not fit all.
“Revitalization” is never finished.
