The Bootstrap team brings decades of research and classroom experience to our work. Most of our team holds doctorates in Computer Science or Education, and nearly our entire frontline staff has been in the trenches, teaching in rural and urban public schools. But the Bootstrap community is larger than the core team - it's hundreds of teachers who share their lesson ideas, feedback and bug reports. It's college CS majors and professional engineers, teaching Bootstrap to young people in their communities.

Joy Straub Joy Straub is one of the leading K-12 Data Science pioneers in the US. Before joining Bootstrap, Joy taught Bootstrap:Data Science and AP Statistics at Mission Vista High School in Oceanside, CA. She launched the first HS Data Science course in San Diego County (and one of the first in CA!), which grew by by 800% in the first year. Joy saw enormous growth in all of her students, and continues to push the envelope when it comes to engaging, rigorous Data Science instruction. Now Joy is working with Bootstrap teachers to ensure their successful implementation of the curriculum. Her success has garnered national attention, and she has advised numerous districts and universities on their Data Science initiatives.


Monique Rousselle Maynard :: Rhode Island Monique has been teaching math to HS students at West Warwick High School for more than 15 years, using Bootstrap in her Algebra 1 classes. Her passion is making the study of mathematics enjoyable while helping students build a strong mathematical foundation for college and career. She is a member of the Better Math Teaching Network and is using her student work with Bootstrap as data to inform her quick-cycle research and development methods on deep engagement and quality justification. She recently worked with RI Learning Champions statewide to craft an exemplar set of proficiencies, performance indicators, and scoring criteria for cross-curricular skills and content areas. Monique introduced her district to Bootstrap Algebra 1 and, this year, co-facilitated professional development for other math teachers in the district.
Adam Newall :: Massachusetts Adam has been teaching math and computer science to 7th and 8th graders in MA Public Schools for over a decade, using Bootstrap:Algebra and Bootstrap:Reactive. He is one of the technology integration specialists for his district, has been a keynote speaker at MassCUE, worked on the subcommittee for the Massachusetts Department of Secondary Education to recommend statewide computer science frameworks, and presents as a Bootstrap ambassador to teachers across the country in a variety of PD events. Adam also leads an after school technology club, "The Nerds in Training", and advocates for gender equality in technology fields by organizing a yearly field trip for girls to visit local tech companies and meet with women in industry. He introduced his district to computer science with Bootstrap and is deeply invested in teaching students to make concrete connections between math, computer science, and real life.
Dan Thomander :: Idaho Dan has been a math teacher at Cassia High School, a public alternative high school in Idaho since 2009. He first found Bootstrap when looking for materials and activities that would inspire his students to re-engage in mathematics. Dan began teaching Bootstrap in 2016 and has since developed courses combining Bootstrap Algebra, Reactive, and Data Science into a singular technical math course for all students at his school. The impact on his students' attitudes and effort was what drove him to that end. "My biggest challenge was getting students to want to learn math. Traditional curricula and activities only worked to inspire temporarily, and resulted in students remembering the activity. Bootstrap changed that - for the first time my students wanted to better understand the math content itself."
Mariana Hernandez :: California Mariana holds a Masters in Education with an emphasis on English Language Learners from San Francisco State University. She has taught math for nearly 20 years at the middle school level. Mariana had been searching for a computer science program that truly made the connection to her math class and Bootstrap fit the bill. She introduced her district to Bootstrap more than five years ago, because she wanted to ensure that her students had equal access and opportunities to explore the real-life connections between math and CS.
Jilian Reynolds :: North Carolina After teaching high school and middle school English/language arts for 12 years, Jilian became a digital integration facilitator for the Moore County School System in North Carolina. As her students started to crave more than just drag and drop block programming, they encouraged her to find a program where they could create their own video games while typing lines of code, and Bootstrap became their absolute favorite. "When you get the opportunity to see students' eyes light up with joy because they say they 'finally feel smart'", Jilian says, "teaching becomes overwhelmingly rewarding." She is in her second year of teaching Bootstrap, and is a huge advocate for incorporating computer science into mainstream K-12 curriculum. In addition to being a Bootstrap Ambassador, she is working towards earning her PhD in Instructional Design and Technology from Old Dominion University.
Allen Antoine :: Texas Allen Antoine, M.Ed, is the associate director of Math and CS of the Rice Office of STEM Engagement (R-STEM). In this role, he specializes in providing lesson ideas, PD, and teacher mentoring in the fields of mathematics and computer science. Some of his specific points of emphasis include culturally responsive teaching strategies, inquiry-based learning, and increasing numeracy. Additionally, Antoine works with the Texas Advanced Computing Center (TACC) through WeTeach_CS. As the project director for the Computing Educator Diversity Initiative, he has championed equity and inclusion in CS in the state of Texas and has traveled across the country facilitating teacher preparation courses for high school computer science competency exams. Antoine holds a BS in Computer Engineering from Xavier University of Louisiana and an M.Ed in Teacher Leadership from Lamar University.
