In 2015, when considering whether to apply for the position of Executive Director for the Computer Science Teachers Association (CSTA), I read the book, Stuck in the Shallow End¸ by Jane Margolis. Computer science (CS) remains one of the least diverse of the STEM disciplines, and Jane's book opened with a compelling comparison between the racial divide in swimming and the divide we see today in CS. Understanding that teachers are critical to access, and how we teach can influence what students might pursue a field, I saw that within CSTA there was opportunity to make a positive difference in the world.
Fast forward to 2017, and thanks to Stephen Ibaraki, I had the opportunity to participate in the AI for Good Summit held in Geneva, Switzerland. The Summit was again a pivotal event, as it crystalized for me the scope, magnitude, and importance of an organization like CSTA to change the world. The work of CSTA addresses two core challenges for the future:
By working together collaboratively, we can solve these challenges. Over the past two years, I saw the pathway to addressing these challenges within CSTA come together in a pair of initiatives: The Big IDEA and the PD Pipeline.
Over the past two years, building upon CSTA's historical interest in equity in CS, we began to change our language around equity. In 2015, our equity work focused mainly on a program with declining participation called "faces of computing," where students created videos that had to showcase some of the diversity within CS. In evaluating the program, and looking at other successful initiatives, we recognized that focus on equity alone is insufficient to achieve equitable outcomes. Thus, we created the Big IDEA as an umbrella for our current and future initiatives in this area.
IDEA stands for Inclusion, Diversity, Equity, and Access. While not the first group to utilize this acronym, the Big IDEA fit well within the needs of our community. By focusing almost exclusively in equity, we heard from many teachers that they did not feel included in the conversation because they identified themselves as "teachers of CS" rather than "CS teachers." That realization uncovered the diversity of perspectives that exist within our membership—which consists of nearly every teaching domain in K-12, and teachers who both come from and work with exceptionally diverse student populations. To achieve CS for All students, we realized that the Big IDEA would be a more effective and holistic approach for focusing our efforts and building engagement in our community.
There is still much work to do. Take for example the challenges of accessibility in the context of disabilities. People with disabilities represent an estimated 15 percent of the world population. Designing for this group of learners can be challenging because disability is not a single construct. It can include physical challenges (related to areas such as vision, hearing, and mobility) as well as cognitive impairments (such as challenges related to reading, memory, and attention deficits).
Accessibility has other implications for CS in education beyond the important category of children with disabilities. Accessibility challenges exist by race, gender, geography, community urbanization, socio-economic status, and many other dimensions. For example, in the U.S. we have entire states where not a single woman, African-American, or Latino take the CS Advance Placement (AP) exam each year. The Latino community, which represents 26% of K-12 students in the U.S., has been underserved by CS education largely due to access issues. We see similar challenges emerging for students in rural communities.
Limits to the Big IDEA, such as those highlighted here around access, become the basis for many forms of institutionalized inequity and can limit access to economic prosperity at multi-generational levels. As one speaker put it at the AI For Good Summit, the lack of diversity and inclusion in CS leads us to "solving mostly white male problems." Over my two years at CSTA, I saw first-hand how teachers are critical for ensuring the Big IDEA becomes reality for children and society.
Organizations like CSTA have it within their mission and influence to make real change around the Big IDEA. Thanks to support and contributions from Google for Education, NCWIT, the Hispanic Heritage Foundation, and many volunteers, CSTA's Big IDEA initiatives reached more than 3.5 million households over the past two years. In 2017 the Big IDEA in CS Education received a prestigious Silver Power of A Award recognizing CSTA and the contributions of both K-12 teachers and those who support them for "their extraordinary contributions and efforts to enrich lives, create a more competitive workforce, drive innovation, and make a better world."
The PD Pipeline
Last year, thanks to a grant from the Infosys Foundation USA, CSTA began development of the Professional Development (PD) Pipeline. The project emerged in response to a set of challenges we heard from our members. These challenges included:
Working with Degreed, this summer CSTA piloted an initial solution to these challenges, via the PD Pipeline. The solution includes several elements. It begins with what will evolve into a developmental self-assessment to help teachers assess their knowledge of CS. That will be linked to developmental pathways to provide teachers with a roadmap to build their confidence and competence in teaching CS. We will provide digital badging and microcredentials to demonstrate teacher progress toward goals and outcomes. There is capacity to provide communities of practice and opportunities to share resources linked to a PD experience, a developmental pathway, or other factors. The solution includes a digital portfolio, enabling a teacher to track all her PD in one place. Finally, nearly all these pieces link back to the K-12 CS Standards and Framework, or to a given state's standards for CS, so that a teacher can track progress against local requirements for licensure or endorsement.
The PD Pipeline is an interesting model as it recognizes that K-12 teachers of CS come from many different academic backgrounds and different exposure to CS. Our best estimate is that 1 in 9 teachers of CS have had a college-level course in CS, and fewer than 7 percent of our membership identify themselves as "CS teachers" first. Most are teachers of another subject who also teach CS. Thus, our 26,000 members include teachers of math, science, career and technical education, English, history, modern languages, art, music, physical education, special education, and many other domains.
We also learned that teachers came into CS with different areas of interest. We have teachers interested in robotics, cybersecurity, game design, artificial intelligence, data analytics, mobile applications, and many other domains of CS. We also recognized that some teachers want to become CS teachers, while others just want to integrate some CS in their classroom.
The PD Pipeline is designed to provide a customized experience for an individual teacher with a goal to help her achieve the level of competence and confidence she desires or requires to be a successful teacher of CS in K-12. With technology changing quickly, and most CS teachers likely to come from the ranks of existing teachers, the PD Pipeline is an effort to address the question: How do we retrain the K-12 educational workforce (i.e., teachers) so that they can prepare their students for the future?
As we look at the future displacement of jobs due to artificial intelligence, many individuals across a range of occupations and industries will need to be retrained. The CSTA PD Pipeline initiative is one approach to solving such a large-scale workforce development problem.
The Big IDEA and the PD Pipeline are two examples of industry-changing initiatives underway at CSTA over the past two years. There is certainly much more that needs to be done in both these areas and others. As with any small non-profit, CSTA is dependent upon the support of organizations and individuals to fulfill its mission. While CSTA was founded by ACM more than a decade ago as part of its ongoing support to K-12 education, today more than ever, CSTA needs support from a broader range of stakeholders to successfully meet the challenges and needs of both the K-12 teacher community, and the organizations and industries that depend on that community.
It was a distinct honor to serve as CSTA's Executive Director for the past two years. By working collaboratively with many stakeholders, we made substantive progress on many fronts as we began the transition of CSTA from a "mom and pop" organization into a world-class professional association. Having accomplished many of the initial strategic goals set in 2015, it is now time for the next Executive Director to continue to build upon the transitional process that we began. I look forward to watching CSTA's future success and encourage readers to support CSTA as the voice for K-12 teachers of CS.
Mark R. Nelson was Executive Director of the Computer Science Teachers Association from June 2015 through July 2017.
