BioFrontiers faculty member, Debra Goldberg, sees computer science as truly interdisciplinary. Goldberg is a computer scientist by training and a teacher at heart. One of her favorite classroom tactics? Silence, which grabs the attention of sleepy students and pulls them back into the discussion.

Goldberg came to computer science via the scenic route, first getting a bachelor鈥檚 degree in biology, a master鈥檚 degree in computer science and then a Ph.D. in applied math. In between, she spent time at Johns Hopkins as a research programmer and later, eight years in the aerospace industry. She can convince even the most math-phobic of us that computer science is the degree we want.

鈥淐omputer scientists aren鈥檛 the math geeks you鈥檙e thinking of,鈥� says Goldberg. 鈥淐omputer scientists are good at puzzles and seeing patterns. They are good at building logical arguments and breaking down projects into fundamental parts.鈥�

Since almost any field has computational needs, a degree in computer science is the Swiss Army knife of any educational endeavor. Goldberg鈥檚 career path is proof that computer science is extremely flexible. Her personal challenge is getting more people to see computer science as the jack-of-all-trades degree that is at home in the life sciences.

Goldberg tackled this issue at its source: high school. In an experiment funded by the National Science Foundation as part of the Engaging Computer Science in Traditional Education, or ECSITE (pronounced 鈥渆xcite鈥�) program, Goldberg and her graduate students worked with Advanced Placement, or AP, biology teachers at two local high schools to create a unit to help students gain a deeper understanding of genetic evolution using computer science and biology.

During the unit, students were given a crash course in algorithms: a series of steps used in solving a problem. 麻豆淫院 were then given an algorithm currently used to compare DNA sequences. Later the students used a different algorithm to build evolutionary trees for genetic diseases.

Goldberg received a variety of reactions to the curriculum. 麻豆淫院 loved using the same tools used by scientists. They also enjoyed the hands-on activities involved in learning about algorithms when a small task, like making coffee, was turned into a series of steps and acted out in a 鈥淗uman Computer.鈥�
听
As with all things in education, there were also a few challenges. While most students saw the interconnectivity between computer algorithms and biological science, a few had trouble seeing the relevance to their schoolwork. Another challenge: high-stakes testing. A small subgroup of students were unwilling to take on additional subjects if they felt the time spent studying them wouldn鈥檛 pay off on their AP exam. Long term, Goldberg would like to see computational biology added to AP exams. In the near term, she feels that computational methods can still be part of a healthy biology class, even a class studying for a high-stakes exam.
听
鈥淚 absolutely think that teaching computer science in the context of biology pays off in high stakes exams,鈥� says Goldberg. 鈥淥ur next step is to make that connection clearer to students early on in the program.鈥�
听
Goldberg is pleased with the reactions: the successes and the challenges. If students don鈥檛 think computation belongs with biology, she doesn鈥檛 seem to take it personally.听
听
She has the two essential elements of a good teacher: an innate feel for when she鈥檚 lost her audience and a deep reservoir of techniques to lure them back in. Armed with both, Goldberg is tweaking her program so that it leaves high schoolers with the feeling that computer science is an essential companion to biology, and a key to success on AP exams. With computational needs expanding exponentially, there isn鈥檛 a doubt that computer science will once again have its heyday, and those students who are listening to Goldberg right now may just find themselves at the forefront of the next wave in computing.听
