Through small-group learning, WES-CS program enhances undergraduate education

Dr. Tracy Lewis-Williams is on a mission.  “There is a place for everyone in computer science,” says the faculty associate in the University of Wisconsin-Madison Department of Computer Sciences.  She’s out to make technology welcoming to all—particularly women and underrepresented minorities.

Nationwide, while 57% of bachelor’s degrees earned in 2013 went to women, only 18% of students receiving an undergraduate degree in computer science were women.  That number reflects a sharp decline since the mid-1980s.

The dearth of female graduates causes ripples throughout the workforce.  Just over a quarter of workers in computing jobs in 2014 were women, and only a small portion were women of color.  (For example, African-American women made up just 3% of the computing workforce in that year.)

To help combat those trends, UW’s computer sciences department offers Wisconsin Emerging Scholars-Computer Sciences (WES-CS), a program to recruit a broader cross-section of UW students to the field.  While aimed at women and targeted minorities, the program is open to any student who wants to benefit from the enhanced learning experiences and sense of community it provides.

The program enhances the department’s introductory programming course with small-group, peer-led learning.  Students earn one additional credit (offered as CS 304) for meeting weekly in teams of six to eight, led by a fellow undergraduate who is often a former WES-CS participant herself.

In addition to classroom work, participants visit tech companies to see the myriad career paths they can take.

Lewis-Williams believes strongly in peer instruction and cites the volume of data supporting it.  “Students feel more comfortable asking peer leaders all types of questions.  And when you have a leader who is only two semesters out from CS 302 themselves, the others feel they can listen to this student, because that peer leader understands what it’s like to be in their shoes.”

Katie Dudenas, a senior CS major from Oshkosh (pictured below), says that teaching a WES-CS section sharpened her own skills.

“When I started teaching, it forced me to become a better Java programmer,” she says. “I had to come up with ways of explaining difficult technical topics in a way that was easy to understand.”Katie Dudenas teaching in classroom

The program also bolstered her interpersonal skills.  “WES-CS has taught me so many things about being a leader:  how to engage a room full of students, how to adapt materials to fit different skill levels, how to foster discussion and encourage students to share knowledge and work together,” she says.  After college, Dudenas plans a career in software engineering.

Willa Cai, a junior from Madison double-majoring in CS and psychology, credits WES-CS with her decision to major in the discipline.

“As a freshman whose first experience with programming of any sort was CS 302, the lectures were overwhelmingly fast-paced,” says Cai.  WES-CS gave her and her peers a chance to delve into concepts more fully.

“Through collaborative exercises and logical thinking problems, I came out of the semester with the skills and confidence to learn more,” affirms Cai.

As program director, Lewis-Williams carries on the legacy of Professor Susan Horwitz, who taught at UW-Madison for nearly thirty years.  Horwitz passed away in summer 2014 after a battle with cancer.

"Susan wanted to make sure women and targeted minorities felt included, and I think we're doing a really good job of making sure that message continues on," says Lewis-Williams.  Future plans include broadening the program to include CS 301 and 367.

The National Science Foundation provided the original funding for WES-CS.  Later, corporate supporters like Google helped it continue.  Now, an endowment set up in Susan Horwitz’s memory ensures that it will continue to flourish.

Many contributors to the Susan B. Horwitz Endowment for Wisconsin Emerging Scholars-Computer Sciences are former students of Horwitz who wanted to honor her accomplishments as an educator.

Students interested in learning more about the program may contact Lewis-Williams or Nikki Lemmon, undergraduate program coordinator for computer sciences.

As Lewis-Williams sees it, the diversity fostered by WES-CS benefits not only students who are exposed to new opportunities, but society at large.

"Computing is about creativity, and if you limit the diversity, you're going to get minds that think alike,” says Lewis-Williams.  By drawing new people into the fold, “that’s how we come up with innovative new technologies that keep the U.S. globally competitive.”
