ESTRELLA draws from an interdisciplinary research team with areas of expertise in electrical and computer engineering, bilingual education, and mathematics education. The team collaborates with middle and high school teachers to co-design lessons that advance student understanding of mathematics through computer programming of visual representations. Teachers conduct action research projects to study topics of interest to them as they implement this integrated curriculum. For example, the middle school teacher focused on fractions and the relationship between distance, rate, and time. The high school teacher focused on geometry and exponential growth and decay. Over the past two years, ESTRELLA has served 101 middle and high school students from primarily Latinx backgrounds and two teachers. Both teachers are supported to implement the integrated mathematics and computer programming curriculum by the researchers and a group of 5 undergraduate engineering students who are from diverse backgrounds. The teachers can choose to add support by including middle school student co-facilitators. The middle school student co-facilitators and the undergraduate student facilitators attend professional development focused on understanding the same mathematical tasks that their students will engage with; best teaching practices; and asset-based approaches to working with culturally and linguistically diverse students.
