This study explores the use of storytelling to motivate middle school girls to study computer programming. It presents the approach of presenting programming as a means to the end of storytelling, highlighting the benefits of storytelling for self-expression and engaging non-programming friends and family. The study includes formative evaluations and workshops with middle school girls, resulting in the development of Storytelling Alice, a version of the programming tool Alice tailored for storytelling purposes. The study also presents the results of summative evaluations, comparing the effectiveness of Storytelling Alice with the generic version of Alice, and demonstrates the positive impact of storytelling on girls' interest and attitudes towards programming.

Using Storytelling to Make Computer Programming Attractive to Middle School Girls Caitlin Kelleher School of Computer Science Carnegie Mellon University www.alice.org
Computer Science is Everywhere • Medicine: Identifying new potential medications • Science: Building robots to explore Mars • Business: Creating new communications networks • Education: Teaching our children to read one on one • Art History: Revealing lost paintings
A Pragmatic Need for Diversity • As human beings, we are best at understanding our own needs. We need to include a representative sample of our population in the design of new technologies. • In the US, women are the largest underrepresented group
Critical Time: Middle School • Middle school is the time during which many girls decide that math and science is not for them. http://www.eric.ed.gov/resources/ericreview/vol6no2/encourage.html
“OK, so I can make the bunny move around, but why would I want to?”
Approach Present programming as a means to the end of storytelling.
Why storytelling? • Girls can come up with a story idea. • Stories provide a graceful introduction to a variety of programming concepts • Stories provide opportunities for self-expression • Stories can be readily appreciated by non-programming friends and family
Developing Storytelling Alice Formative Evaluation: Observe middle school girls (and some boys) creating stories in Alice Design and Implement: Improve Alice
Subjects: Formative Evaluation • ~ 120 Girl Scouts from within 1.5 hours of Pittsburgh • ~ 30 Local home-schooled kids • ~ 60 Campers at STEM camps
Over 18 months, ~15 iterations Formative Evaluation: Observe middle school girls (and some boys) creating stories in Alice Design and Implement: Improve Alice
Workshop Process • Create a storyboard • Complete the Storytelling Alice tutorial • Build story in version of Storytelling Alice
3-Step Storyboarding • DVD box description • Setting, action, purpose for each scene. • 6-9 drawn frames with textual descriptions per scene.
Motivation for Programming Constructs • Sequences – 100% • Subroutines (through the need for multiple scenes) – 87% • Methods with parameters (through character methods) – 52% • Loops – 48%
Storytelling Alice: Say, think Play sound Walk to, walk offscreen, walk Move Sit On, Lie on Kneel Fall Down Stand Up Straighten Look at, look Turn to face, Turn away from Turn Touch Keep Touching Generic Alice: Move Turn Roll Resize Play Sound Move to Move toward, Move away from Orient to Turn to Face, point at Set point of view to Set Pose Stand up Move at speed, turn at speed, roll at speed Constrain to face, Constrain to point at Change the basic animations to match what kids want to create

Showing a story is appealing 2% story kids show their non-story world instead of their story world 34% non-story kids show their story world instead of their non-story world p < 0.001
Users of the storytelling version show more evidence of engagement/motivation p = 0.001
The Future: Alice v3.0 • Now beginning design and development • Will dump “real” Java and a graceful path • Will be driven by findings about storytelling, and will have high quality characters and animations. • Will be targeted (possible multiple configurations/flavors) at everyone from 5th grade to college freshmen.
