My CSTA Story
Charity’s journey as “unofficial brand ambassador for CSTA” began when she received a scholarship to attend the 2019 CSTA Annual Conference. There, she learned about CSTA’s then–brand new Equity Fellowship and went on to join its first cohort! Since then, Charity has written several articles for CSTA’s The Voice, served as the first Equity Strand Lead of the Annual Conference Committee, and led CSTA’s Nominations and Elections Committee. She became chair of the Board of Directors in July 2023. “#iLoveMyCSTA, and I’m passionately committed to our organization’s growth as we support and advocate for our teachers to be seen, heard, and valued.”
As part of the University of Illinois Urbana-Champaign’s computer science department, Charity Freeman is supporting the launch of two new graduate degree programs in her hometown of Chicago. Tried and true, she’s a diehard Bears fan, staunch supporter of the “Sears Tower,” and a firm believer that ketchup doesn’t belong on hot dogs. Her determined spirit carries into her work in CS education throughout the state of Illinois, where she helps lead the newly formed ECEP Illinois team. As a governor-appointed member of the Illinois P–20 Council, she co-chairs a project-based working group on scaling K–12 CS education. Charity is also the lead instructor of the Teaching Methods in Computer Science endorsement course for in-service teachers at UIUC’s College of Education.
In her spare time… That’s funny. Charity’s rarely-enjoyed hobbies include watching football, playing tennis, and enjoying dinner with her family. Meanwhile, she’ll continue focusing on building and sustaining K–20 CS education ecosystems that systematically identify and address disparities in opportunities, outcomes, and representation in computing education.
International Representative (October 2022 – June 2024)
My CSTA Story
Although Edge had attended CSTA conferences and became a bag stuffer in Omaha in 2018, he didn’t really know what to expect, or that it would lead him to love the people who were involved. From stuffing bags to meeting with CSTA’s executive director to leading the first non-American CSTA chapter to serving on the board, Edge is inspired to keep going by the people he shares the love with and the people who share it along the way.
Edge is currently a licensed high school CS teacher, and he has been teaching CS and computer education since 2005. He has taught at several of the premier private high schools in the Philippines, and he spent a considerable amount of time teaching theoretical CS and software development at the tertiary level. While working at the university level, Edge contributed to the recommendations for the curricula of bachelor’s degrees in computer science and entertainment and multimedia computing. Edge now works to generate computer science content and curricula at the elementary, middle, and high school levels.

My CSTA Story
Since becoming a CS teacher in 2017, Delmar has been a driving force in creating a more equitable computer science culture for students at his school. As a 2023 CSTA Equity Fellow, his dedication to increasing equity in computer science extends beyond the classroom. Delmar tirelessly advocates for underrepresented students and organizes extracurricular activities to engage and empower them. Through his work within and outside of the classroom, Delmar strives to break down barriers, empower underrepresented students, and cultivate an environment where everyone feels valued, supported, and capable of achieving their dreams in the field of computer science.
Delmar Wilson has been a public school educator for seventeen years, and he has taught mathematics, AP Computer Science Principles, and Cambridge Thinking Skills at Miami Springs Senior High. In addition to his teaching responsibilities, Delmar is chair of the math department, ESSAC chairperson, union steward, and head coach of boys’ varsity basketball.
As Delmar began working on his doctorate degree in 2013, he came to the realization that there weren’t enough minorities in computer science. He created an AP CSP course at his school and began by recruiting his ninth graders, none had ever dreamed of taking a computer science course, much less an AP course. Over the years, this course has become a student favorite, and in 2021 he started the school’s first Computer Science Honor Society. As a veteran teacher, Delmar continues to push CS forward by utilizing his CS Honor Society to broaden CS participation and by introducing students to CS during Computer Science Week. Delmar believes that computer science is not just for a select few; it is for everyone. It has the power to transcend boundaries, break barriers, and unlock the unlimited potential within each and every student. As teachers of the 21st century, we have a commitment to ensure that we are effectively preparing our students to be future leaders.
