In computing education, we have only just started developing methods for accurately measuring a student's understanding of introductory computing, let alone characterizing a whole classroom, school, or university system. As part of evaluating the impact of "Georgia Computes!" we sought an understanding the factors influencing undergraduate enrollment in introductory computing for an entire state in the United States of America. We gathered surveys from over 1400 undergraduate students in introductory computing classes from 19 higher-education institutions in a single state. The analysis provided insight into the impact of "Georgia Computes!", into the connections between stages of the computing education pathways, and how factors that influence students' pursuit of computing differ between genders and majority/minority group students.

Georgia Computes! (GaComputes) was a six-year (2006)(2007)(2008)(2009)(2010)(2011)(2012) project to improve computing education across the state of Georgia in the United States, funded by the National Science Foundation. The goal of GaComputes was to broaden participation in computing and especially to engage more members of underrepresented groups which includes women, African Americans, and Hispanics. GaComputes' interventions were multi-faceted and broad: summer camps and after-school/weekend programs for 4th-12th grade students, professional development for secondary teachers, and professional development for post-secondary instructors/faculty. All of the efforts were carefully evaluated by an external team (led by the third and fourth authors), which provides us with an unusually detailed view into a computing education intervention across a region (about 59K square miles, about 9.9 million residents). Our dataset includes evaluations from over 2,000 students who attended after-school or weekend workshops, over 500 secondary school teachers who attended professional development, 120 post-secondary teachers who attended professional development, and over 2,000 students who attended a summer day (non-residential) camp. GaComputes evaluations provide insight into details of interventions and into influences on student motivation and learning. In this article, we describe the results of these evaluations and describe how GaComputes broadened participation in computing in Georgia through both direct interventions and indirect support of other projects.

Science communication and outreach are essential for training the next generation of scientists and raising public awareness for science. Providing effective science, technology, engineering, and mathematics (STEM) educational outreach to students in classrooms is challenging because of the need to form partnerships with teachers, the time commitment required for the presenting scientist, and the limited class time allotted for presentations. In our Present Your Ph.D. Thesis to a 12-Year Old outreach project, our novel solution to this problem is hosting a youth science workshop (YSW) on our university campus. The YSW is an interpersonal science communication and outreach experience in which graduate students from diverse scientific disciplines introduce middle and high school students to their cutting-edge research and mentor them to develop a white-board presentation to communicate the research to the workshop audience. Our assessment of the YSW indicated that participating young students expressed significantly more positive attitudes toward science and increased motivation to work in a STEM career after attending the workshop. Qualitative follow-up interviews with participating graduate students' show that even with minimal time commitment, an impactful science communication training experience can be achieved. The YSW is a low-cost, high-reward educational outreach event amenable to all disciplines of science. It enhances interest and support of basic science research while providing opportunities for graduate students to engage with the public, improve their science communication skills, and enhance public understanding of science. This YSW model can be easily implemented at other higher education institutions to globally enhance science outreach initiatives.
