A group of high school girls in Mesa Public Schools spent their fall break learning to code in R, a computer language used for statistical analysis. This workshop was the brainchild of Jessica Guo, a CAP graduate student, who is passionate about coding and determined to bring more girls into STEM (science, technology, engineering, and mathematics). A graduate of Mesa Public Schools herself, Jessica is part of the ASU/NASA Space Grant program. In the workshop that Jessica led, girls accessed large, publicly-available datasets and used coding to analyze the data and to create graphs, which they presented to their peers. Among the datasets that the girls used were ones created by LTER Network sites.
