   This work discusses ongoing experiences in creating interdisciplinary solutions to the development of cybersecurity/computer science skills for K-12 teachers. Participants for this work were K-12 teachers; the work was conducted during the summer semester of 2020. Nine K-12 teachers enrolled in the pilot course, and five K-12 teachers completed modules 0 & 1 of the cybersecurity course. This work describes a month long, self-paced cybersecurity micro-credential which consisted of an introduction to cybersecurity and the CIA Triad (Confidentiality, Integrity, and Accessibility). The primary research question explores the extent to which the cybersecurity micro-credential was considered helpful in understanding cybersecurity concepts and principles. The authors utilized quantitative and qualitative data collection via four methods: 1) content knowledge quiz (quantitative); 2) focus group (qualitative); 3) five semi-structured interviews (qualitative) and 4) two bi-weekly progress reports (qualitative). Qualitatively, focus group, semi-structured interview questions, and bi-weekly progress reports were coded and grouped into major themes by searching descriptive words. Quantitatively, a moderate positive relationship was found between post-test scores and total time in hours spent on modules 0 & 1. The main limitation is the sample size (n=5), which is too small to produce generalizable results. The work showcases innovative tools for teaching cybersecurity.

   K-12 Computer Science (CS) education has seen remarkable growth recently, driven by the increasing focus on CS and Computational Thinking (CT) integration. Despite the abundance of Professional development (PD) programs designed to prepare future CS teachers with the required knowledge and skills, there is a lack of research on how teachers' perceptions and attitudes of CS and CT evolve before and after participating in these programs. To address this gap, our exploratory study aims to study the dynamics of pre-and in-service teachers' experiences, attitudes, and perceptions towards CS and CT through their participation in a K-12 CS education micro-credential program. In this study, we employed topic modeling to identify topics that emerged from teachers' written pre- and post-CS autobiographies, conducted statistical analysis to explore how these topics evolve over time and applied regression analysis to investigate the factors influencing these dynamics. We observed a shift in teachers' initial feelings of fear, intimidation, and stress towards confidence, fun, and feeling competent in basic CS, reflecting a positive transformation. Regression analysis revealed that features, such as experienced teacher status and CT conceptual understanding, correlate with participants' evolving views. These observed relationships highlight the micro-credential's role in not only enhancing technical competency but also fostering an adaptive, integrative pedagogical mindset, providing new insights for course design.

3. “They helped me through the semester”: electronic instructor messages can foster the instructor-student relationship

   ABSTRACT Building rapport between instructors and students is a challenge, especially in large classes and in online environments. Previous work has shown that non-content Instructor Talk can foster positive student-teacher relationships, but less is known about non-content talk in electronic instructor messages. Here, we used the established Instructor Talk framework to craft positively phrased electronic messages that were sent through the course’s learning management system to students enrolled in an introductory biology course at a large public institution. We examined both close- and open-ended survey responses (n= 226) to assess students’ perceptions of the electronic messages, the course, and their instructor. Of the established Instructor Talk categories, the building student/instructor relationship category was most memorable to students. Encouragingly, 61% of students indicated they “liked the course more” and 88% indicated they “liked the instructor more” in response to the electronic messages. This demonstrates that implementing positively phrased Instructor Talk into electronic communication is an effective way to build rapport between instructors and students.

4. Assisting K-12 Teachers to Make the Connection between Computational Thinking in Cybersecurity Unplugged Activities and Mathematical Mindset through A Cybersecurity Micro-credential

   This poster focuses on K-12 STEM teachers' computational thinking while using unplugged cybersecurity activities and exploring cybersecurity applications within self-paced micro-credentials. As a result, they share the most successful and challenging unplugged cybersecurity activities. The pilot micro-credentials were created to assess their effectiveness at enabling K-12 teachers to meaningfully their own materials to develop students’ STEM readiness and increase their engagement with cybersecurity, while enabling unplugged activities to transfer to a more mathematical mindset. The two pilot studies, focusing on K-12 teacher participants, included an initial micro-credential in the 2020 summer (n=5) which informed and enhanced a second micro-credential module sequence in the fall 2020 semester (n=16). Pilot 2 consisted of a total of five modules after refining it from feedback from pilot 1, which had only 2 modules. Researchers performed a mixed-methods study, which included qualitative data collected through interviews and focus groups. Additionally, content knowledge questions and attitude surveys were also used to collect both qualitative and quantitative data. Results indicate that the majority of K-12 teachers who participated in the micro-credential pilots were able to make connections between unplugged activities and a mathematical mindset. The poster presents these findings and also includes additional resources for further exploration and inspiration.

5. Examining the Impact of Interpersonal Interactions on Course-level Persistence Intentions Among Online Undergraduate Engineering Students

   This research paper examines the influence of interpersonal interactions on the course-level persistence intentions of online undergraduate engineering students. Online learning is increasing in enrollment and importance in engineering education. Online courses also continue to confront issues with comparatively higher course dropout levels than face-to-face courses. This study correspondingly explores relevant student perceptions of their online course experiences to better understand the factors that contribute to students’ choices to remain in or drop out of their online undergraduate engineering courses. Data presented in this study were collected during fall 2019 and spring 2020 from three ABET-accredited online undergraduate engineering courses at a large southwestern public university: electrical engineering, engineering management, and software engineering. Participants were asked to respond to surveys at 12-time points during their 7.5-week online course. Each survey measured students’ perceptions of course LMS dialog, perceptions of instructor practices, and peer support for completing the course. Participants also reported their intentions to persist in the course during each survey administration. A multi-level modeling analysis revealed that LMS dialog, perceptions of instructor practices, and peer support are related to course persistence intentions. Time was also a significant predictor of persistence intentions and indicated that the course persistence intentions decrease towards the end of the course. Additionally, interactions between demographic variables and other predictors (perceptions of course LMS dialog, perceptions of instructor practices, and perceptions of peer support) were significant. With the increase in perceptions of course LMS dialog, perceptions of instructor practices, and perceptions of peer support, there was a relatively smaller increase in the persistence intentions of veterans than non-veterans. There is relatively more increase in the persistence intentions of females than males as their perceptions of instructor practices increase. Finally, increasing perceptions of peer support led to a relatively larger increase in the persistence intentions of non-transfer students than transfer students and a relatively smaller increase in persistence intentions of students working full-time than other students.
