The Impact of Exploring Computer Science in Wisconsin: Where Disadvantage is an Advantage

Assessing the impact of regional or statewide interventions in primary and secondary school (K-12) computer science (CS) education is difficult for a variety of reasons. Qualitative survey data provide only a limited view of impacts, but quantitative data can be notoriously difficult to acquire at scale from large numbers of classrooms, schools, or local educational authorities. In this paper, we use several publicly available data sources to glean insights into public high school CS enrollments across an entire U.S. state. Course enrollments with NCES course codes and local descriptors, school-level demographic data, and school geographic attendance boundaries can be combined to highlight where CS offerings persist and thrive, how CS enrollments change over time, and the ultimate quantitative impact of a statewide intervention. We propose a more appropriate level of data aggregation for these types of quantitative studies than has been undertaken in previous work while demonstrating the importance of a contextual aggregation process. The results of our disparate impact analysis for the first time quantify the impact of a statewide Exploring Computer Science (ECS) program rollout on economic groups across the region. Our blueprint for this analysis can serve as a template to guide and assess large-scale K-12 CS interventions wherever detailed project evaluation methods cannot scale to encompass the entire study area, especially in cases where attribute heterogeneity is a significant issue

STRATEGIES FOR RECRUITING AND RETAINING FEMALE STUDENTS IN SECONDARY COMPUTER SCIENCE

Thesis (Ph.D.) - Indiana University, School of Education, 2019There is an increased push for integrating computer science (CS) into K-12 classrooms across the U.S. However, there are also significant CS equity issues in K-12, higher education, and the workforce. This study explored the gender gap in CS and efforts to broaden female participation in computing. I employed an ethnographic case study design to explore a school where female participation was higher than the state average. In order to explore what may have contributed to these higher female participation numbers, I spent three months conducting observations, interviews, personal reflections, and collecting student reflection data. Based on the data generated during the study, I found three levels of impact that appeared to be beneficial for broadening participation: practices that supported teachers; practices that supported students; and practices that supported the overall CS culture. For teachers, receiving support from administration by having the opportunity to coteach, and receiving recruitment support from counselors both appeared to be beneficial. For students, receiving personalized learning experiences, developing a growth mindset, engaging in problem-solving and creative experiences, and participating in afterschool clubs all appeared to be beneficial for broadening participation. Finally, for the CS culture, incorporating female role-models and designing a more welcoming classroom space appeared to be beneficial for broadening participation. Overall, gender-based stereotypes did not appear to be present in the FVHS CS community, potentially as a result of these strategies. However, while gender-based stereotypes did not emerge, nerd-genius stereotypes were common. Teachers tended to focus on the nerd side of nerd-genius stereotypes, while students tended to focus on the genius side. Despite this focus on nerd-genius stereotypes, students also commonly held the perception that a computer scientist could be any type of person, suggesting that for this specific context, stereotypes may be moving in a positive direction. Overall, teachers and schools that are interested in broadening participation might consider including the strategies that were seen here as being potentially beneficial for broadening female participation

Translanguaging About, With, and Through Code and Computing: Emergent Bi/multilingual Middle Schoolers Forging Computational Literacies

As computing pervades more aspects of life, and as Computer Science for All (CS for All) initiatives roll out across the U.S., the field must understand the experiences and language practices of emergent bi/multilingual K-12 students and use that knowledge to drive equitable pedagogical and programmatic approaches. But little is known about how emergent bi/multilingual students — a growing population that school systems have often viewed with deficit-based lenses and have thus struggled to educate equitably — use language in the context of CS education. This dissertation addresses this gap by (1) qualitatively documenting and using asset-based frames to analyze moments when emergent bilingual middle schoolers translanguaged (flexibly orchestrated linguistic, semiotic, and technological resources) as they participated in computational literacies in CS-integrated Language Arts, English-as-a-New Language, and Social Studies units co-designed by teachers and researchers working together in a research-practice partnership. It also (2) captures insights about how students understood their meaning-making choices in those moments and (3) uses findings from this empirical work to generate theory about the relationships between translanguaging and computational literacies. Findings provide evidence that emergent bi/multilingual students’ diverse language practices are assets in CS education, and enabled the forging of new meaningful computational literacies. This project lays groundwork for CS practitioners to meaningfully include emergent bi/multilingual students and for bilingual education to consider computing’s role in languaging and expression

The Case for Improving U.S. Computer Science Education

Despite the growing use of computers and software in every facet of our economy, not until recently has computer science education begun to gain traction in American school systems. The current focus on improving science, technology, engineering, and mathematics (STEM) education in the U.S. school system has disregarded differences within STEM fields. Indeed, the most important STEM field for a modern economy is not only one that is not represented by its own initial in "STEM" but also the field with the fewest number of high school students taking its classes and by far has the most room for improvement—computer science

Science and Engineering Labor Force

[Excerpt] Like most developed economies, the United States increasingly depends on a technically skilled workforce, including scientists and engineers. Workers for whom knowledge and skill in S&E are central to their jobs have an effect on the economy and the wider society that is disproportionate to their numbers: they contribute to research and development, increased knowledge, technological innovation, and economic growth. Moreover, the knowledge and skills associated with science and engineering have diffused across occupations and become more important in jobs that are not traditionally associated with S&E

Computer Programming Effects in Elementary: Perceptions and Career Aspirations in STEM

The development of elementary-aged students’ STEM and computer science (CS) literacy is critical in this evolving technological landscape, thus, promoting success for college, career, and STEM/CS professional paths. Research has suggested that elementary- aged students need developmentally appropriate STEM integrated opportunities in the classroom; however, little is known about the potential impact of CS programming and how these opportunities engender positive perceptions, foster confidence, and promote perseverance to nurture students’ early career aspirations related to STEM/CS. The main purpose of this mixed-method study was to examine elementary-aged students’ (N = 132) perceptions of STEM, career choices, and effects from pre- to post-test intervention of CS lessons (N = 183) over a three-month period. Findings included positive and significant changes from students’ pre- to post-tests as well as augmented themes from 52 student interviews to represent increased enjoyment of CS lessons, early exposure, and its benefits for learning to future careers

Preparing the Future Workforce: Science, Technology, Engineering and Math (STEM) Policy in K12 Education in Wisconsin

Last December, the Science, Technology, Engineering, and Mathematics (STEM) Education Coalition - a national organization of more than 600 groups representing knowledge workers, educators, scientists, engineers, and technicians wrote to President-elect Obama urging him to "not lose sight of the critical role that STEM education plays in enabling the United States to remain the economic and technological leader of the 21st century global marketplace." While that imperative appears to have resonated in Washington, has it and should it resonate in Madison? This report attempts to answer that question by examining the extent to which STEM skills are a necessity for tomorrow's Wisconsin workforce, whether our schools are preparing students to be STEM-savvy workers, and where STEM falls in the state's list of educational priorities

Toward Universal Broadband in Rural Alaska

The TERRA-Southwest project is extending broadband service to 65 communities in the Bristol Bay, Bethel and Yukon-Kuskokwim regions. A stimulus project funded by a combination of grants and loans from the Rural Utilities Service (RUS), TERRA-Southwest has installed a middle-mile network using optical fiber and terrestrial microwave. Last-mile service will be through fixed wireless or interconnection with local telephone networks. The State of Alaska, through its designee Connect Alaska, also received federal stimulus funding from the National Telecommunications and Information Administration (NTIA) for tasks that include support for an Alaska Broadband Task Force “to both formalize a strategic broadband plan for the state of Alaska and coordinate broadband activities across relevant agencies and organizations.” Thus, a study of the impact of the TERRA project in southwest Alaska is both relevant and timely. This first phase provides baseline data on current access to and use of ICTs and Internet connectivity in rural Alaska, and some insights about perceived benefits and potential barriers to adoption of broadband. It is also intended to provide guidance to the State Broadband Task Force in determining how the extension of broadband throughout the state could contribute to education, social services, and economic activities that would enhance Alaska’s future. Results of the research could also be used proactively to develop strategies to encourage broadband adoption, and to identify applications and support needed by users with limited ICT skills.Connect Alaska.
