There is an ongoing need to integrate computing-related education within existing K-12 curriculum to maintain global competitiveness and security. Our research addresses the challenge of equitable access to concepts from across the computing spectrum - from computing systems to computer science and computational thinking. The research focuses on overcoming the digital divide by enabling K-12 educators to become conduits for computing education, thereby equipping students with essential computational skills and knowledge. Through two National Science Foundation awards, the team used a mixed-methods approach to develop and assess several traditional and non-traditional teacher engagements. These engagements included a week-long professional development program for K-8 educators and librarians, aimed at designing computing lessons for integration into non-CS disciplines, and a six-week research experience for educators, focused on infusing CS and research concepts into classroom environments. Each of these two engagements was repeated for three consecutive years for a total of six engagements. The assessment of these methods involved qualitative analyses of educator feedback, lesson plan evaluations, and quantitative measures of student engagement and learning outcomes. Our collected artifacts includes over 300 teacher-created and led, innovative lessons spanning a broad spectrum of subjects and educational levels. These lessons have directly engaged several thousand students, demonstrating a marked improvement in computational thinking skills across diverse student populations. Moreover, the engagements have resulted in a significant shift towards viewing computational thinking as an integral element of K-12 education, rather than a standalone discipline. This work highlights the process through which educators can become empowered to integrate computing principles across various subjects and also showcases the tangible benefits of such integration. By facilitating the authentic, teacher-led development of computing lessons and their integration into existing curricula, our research underscores the critical role of educators in bridging the digital divide and fostering a comprehensive educational experience that includes topics from across the computing spectrum.more » « less

In recent years, Wyoming has developed Computer Science (CS) standards for adoption and use within K-12 classrooms. These standards, adopted in January of 2022, go into effect for the 2022-2023 school year. The University of Wyoming has offered two different computer science week-long professional developments for teachers. Many K-12 teachers do not have a CS background, so developing CS lessons plans can be a challenge in these PDs.This research study is centered around three central questions: 1) To what extent did K-12 teachers integrate computing topics into their PD created lesson plans; 2) How do the teacher perceptions from the two CS PDs compare to each other; and 3) How was the CS PD translated to classroom activity? The first PD opportunity (n=14), was designed to give hands-on learning with CS topics focused on cybersecurity. The second PD opportunity (n=28), focused on integrating CS into existing curricula. At the end of each of these PDs, teacher K-12 teachers incorporated CS topics into their selected existing lesson plan(s). Additionally, a support network was implemented to support excellence in CS education throughout the state. This research study team evaluated the lesson plans developed during each PD event, by using a rubric on each lesson plan. Researchers collected exit surveys from the teachers. Implementation metrics were also gathered, including, how long each lesson lasted, how many students were involved in the implementation, what grades the student belonged to, the basic demographics of the students, the type of course the lesson plan was housed in, if the K-12 teacher reached their intended purpose, what evidence the K-12 teacher had of the success of their lesson plan, data summaries based on supplied evidence, how the K-12 teachers would change the lesson, the challenges and successes they experienced, and samples of student work. Quantitative analysis was basic descriptive statistics. Findings, based on evaluation of 40+ lessons, taught to over 1500 K-12 students, indicate that when assessed on a three point rubric of struggling, emerging, or excellent - certain components (e.g., organization, objectives, integration, activities & assessment, questions, and catch) of K-12 teacher created lessons plans varied drastically. In particular, lesson plan organization, integration, and questions each had a significant number of submissions which were evaluated as "struggling" [45%, 46%, 41%] through interesting integration, objectives, activities & assessment, and catch all saw submissions which were evaluated as "excellent" [43%, 48%, 43%, 48%]. The relationship between existing K-12 policies and expectations surfaces within these results and in combination with other findings leads to implications for the translation of current research practices into pre-collegiate PDs.more » « less

Computer science, cybersecurity education, and microcredentials are becoming more pervasive in all levels of the educational system. The purpose of this study was partnering with precollegiate teachers: (1) to investigate the self-efficacy of 30 precollegiate teacher participants towards computer science before, during, and after three iterations of a cybersecurity microcredential, and (2) to make changes to the cybersecurity microcredential to improve its effectiveness. The authors explored what teachers need in a microcredential. The first Cohort (n = 5) took the microcredential sequence over 28 days in the summer of 2020, the second Cohort (n = 16) took it over 42 days in the fall of 2020, and the third Cohort (n = 9) took it over 49 days in the summer of 2021. The authors investigated three research questions and used a systems thinking approach while developing, evaluating, and implementing the research study. The researchers used quantitative methods in the collection of a self-efficacy subscale survey to assess whether the precollegiate teachers’ beliefs about computer science changed, and then used qualitative methods when conducting semi-structured teacher participant interviews to address the research questions. The findings show that the precollegiate teachers’ self-efficacy scores towards computer science increased, and that there are areas in need of attention, such as resources and implementation, when creating microcredentials. The implications of this research include the importance of purposefully crafting microcredentials and professional developments, including aspects of creating effective partnerships.more » « less
