benefit of all students. CMU, with its
School of Computer Science and the
seven departments within the school,
offers a wide variety of courses—some
of which are applications focused—
but the core CS curriculum and a wide
variety of advanced courses have become increasingly theory driven and
rigorous without impacting students’
retention and success.
Cultural Change Is Key—And
It Can Change at the Micro Level
In 1999, CMU dropped the program-ming/CS background requirement
from the admissions criteria and added leadership potential while keeping
high SAT scores, particularly in math
and science. Dropping this requirement was prompted by a valuable
finding from the 1995–1999 research
studies.
11 Various entry levels into the
first-year courses were created for students with little to no background.
Other major contributing factors included: CMU Dean Raj Reddy’s vision
to produce leaders in the field that
also brought institutional support for
change; Lenore Blum joined the CS
faculty bringing long-standing expertise and advocacy for women in science and math; and the development
of Women@SCS, an organization of
faculty and students (mostly, but not
all, women) led by a Student Advisory
Committee, working to ensure that
the professional experiences and social opportunities for women reflect
the implicit opportunities for those in
the majority (see https://www.women.
cs.cmu.edu/).
These changes brought in many
more women, and more students—
both male and female—with a broader
range of characteristics and interests.
We started to see a more balanced
student body, balanced in terms of
gender, of student characteristics,
and balanced in terms of leveling-the-
playing-field opportunities for women
throughWomen@SCS.Int his more
balanced environment our observa-
tions and series of studies, including
our 2016–2017 study,
3–7 found CMU
students relating to CS through a spec-
trum of attitudes along with many
more similarities than differences.
For example, we found most students
(men and women) have a deep inter-
est in computer science and want to
successful in CS we needed to change
the culture and environment, and de-
velop and sustain programs that work
to level the playing field without mak-
ing women feel like a separate species.
However, we did not need to change
the curriculum to be “pink” in any way.
Indeed, gender difference approaches,
which tend to assume CS should be
changed to suit women’s presumed in-
terests, have not provided satisfactory
explanations for the low participation
of women in CS. Indeed, beliefs in a
gender divide may actually be deter-
ring women from seeing themselves in
male-dominated fields.
We hope the CMU story can help
challenge the gender divide in CS, show
that women can master this field suc-
cessfully, and inspire others to think
more broadly about intellectual and ac-
ademic expectations. We acknowledge
that the CMU experience may not be
fully generalizable. For example, CMU
is a private institution that may not
have some of the constraints state in-
stitutions have because of various laws
and regulations. While recognizing the
potentially limited generalizability of
our experiences, we summarize five key
takeaways we believe may be replicated
at other institutions where there is the
motivation for change.
Women Do Not Need
a Female-Friendly Curriculum
From 1999 onward some dramatic
changes occurred at CMU, changes
that contributed to a successful and
much-improved undergraduate experience for students in the CS major. Most
significantly these changes led from
women feeling out of place and small
in number to being well represented,
being an integral part of the CS culture,
contributing to the culture, and being
successful in the field alongside their
male peers. Indeed, men and women
graduate at the same rate. This success occurred without compromises
to academic integrity, without changing the curriculum to suit women, nor
by accommodating what are perceived
to be “women’s” learning styles and
attitudes to CS. Changes to the CMU
curriculum, as in any department committed to providing the best academic
program possible are made for the
