   Computer programming is rarely accessible to K–12 students, especially for those from culturally and linguistically diverse backgrounds. Middle school age is a transitioning time when adolescents are more likely to make long-term decisions regarding their academic choices and interests. Having access to productive and positive knowledge and experiences in computer programming can grant them opportunities to realize their abilities and potential in this field.

   This study focuses on the exploration of the kind of relationship that bilingual Latinx students developed with themselves and computer programming and mathematics (CPM) practices through their participation in a CPM after-school program, first as students and then as cofacilitators teaching CPM practices to other middle school peers.

   An after-school program, Advancing Out-of-School Learning in Mathematics and Engineering (AOLME), was held at two middle schools located in rural and urban areas in the Southwest. It was designed to support an inclusive cultural environment that nurtured students’ opportunities to learn CPM practices through the inclusion of languages (Spanish and English), tasks, and participants congruent to students in the program. Students learned how to represent, design, and program digital images and videos using a sequence of 2D arrays of hexadecimal numbers with Python on a Raspberry Pi computer. The six bilingual cofacilitators attended Levels 1 and 2 as students and were offered the opportunity to participate as cofacilitators in the next implementation of Level 1.

   This longitudinal case study focused on analyzing the experiences and shifts (if any) of students who participated as cofacilitators in AOLME. Their narratives were analyzed collectively, and our analysis describes the experiences of the cofacilitators as a single case study (with embedded units) of what it means to be a bilingual cofacilitator in AOLME. Data included individual exit interviews of the six cofacilitators and their focus groups (30–45 minutes each), an adapted 20-item CPM attitude 5-point Likert scale, and self-report from each of them. Results from attitude scales revealed cofacilitators’ greater initial and posterior connections to CPM practices. The self-reports on CPM included two number lines (0–10) for before and after AOLME for students to self-assess their liking and knowledge of CPM. The numbers were used as interview prompts to converse with students about experiences. The interview data were analyzed qualitatively and coded through a contrast-comparative process regarding students’ description of themselves, their experiences in the program, and their perception of and relationship toward CPM practices.

   Findings indicated that students had continued/increased motivation and confidence in CPM as they engaged in a journey as cofacilitators, described through two thematic categories: (a) shifting views by personally connecting to CPM, and (b) affirming CPM practices through teaching. The shift in connecting to CPM practices evolved as students argued that they found a new way of learning mathematics, in that they used mathematics as a tool to create videos and images that they programmed by using Python while making sense of the process bilingually (Spanish and English). This mathematics was viewed by students as high level, which in turned helped students gain self-confidence in CPM practices. Additionally, students affirmed their knowledge and confidence in CPM practices by teaching them to others, a process in which they had to mediate beyond the understanding of CPM practices. They came up with new ways of explaining CPM practices bilingually to their peers. In this new role, cofacilitators considered the topic and language, and promoted a communal support among the peers they worked with.

   Bilingual middle school students can not only program, but also teach bilingually and embrace new roles with nurturing support. Schools can promote new student roles, which can yield new goals and identities. There is a great need to redesign the school mathematics curriculum as a discipline that teenagers can use and connect with by creating and finding things they care about. In this way, school mathematics can support a closer “fit” with students’ identification with the world of mathematics. Cofacilitators learned more about CPM practices by teaching them, extending beyond what was given to them, and constructing new goals that were in line with a sophisticated knowledge and shifts in the practice. Assigned responsibility in a new role can strengthen students’ self-image, agency, and ways of relating to mathematics.

2. Conducting the Pilot Study of Integrating AI: An Experience Integrating Machine Learning into Upper Elementary Robotics Learning (Work in Progress)

   Xu, G. ; Zabner, D. ; Cross, J. ; Nadler, D. ; Coxon, S. ; Engelkenjohn, K. ( June 2023 , ASEE annual conference exposition proceedings)

   Artificial Intelligence (AI) enhanced systems are widely adopted in post-secondary education, however, tools and activities have only recently become accessible for teaching AI and machine learning (ML) concepts to K-12 students. Research on K-12 AI education has largely included student attitudes toward AI careers, AI ethics, and student use of various existing AI agents such as voice assistants; most of which has focused on high school and middle school. There is no consensus on which AI and Machine Learning concepts are grade-appropriate for elementary-aged students or how elementary students explore and make sense of AI and ML tools. AI is a rapidly evolving technology and as future decision-makers, children will need to be AI literate[1]. In this paper, we will present elementary students’ sense-making of simple machine-learning concepts. Through this project, we hope to generate a new model for introducing AI concepts to elementary students into school curricula and provide tangible, trainable representations of ML for students to explore in the physical world. In our first year, our focus has been on simpler machine learning algorithms. Our desire is to empower students to not only use AI tools but also to understand how they operate. We believe that appropriate activities can help late elementary-aged students develop foundational AI knowledge namely (1) how a robot senses the world, and (2) how a robot represents data for making decisions. Educational robotics programs have been repeatedly shown to result in positive learning impacts and increased interest[2]. In this pilot study, we leveraged the LEGO® Education SPIKE™ Prime for introducing ML concepts to upper elementary students. Through pilot testing in three one-week summer programs, we iteratively developed a limited display interface for supervised learning using the nearest neighbor algorithm. We collected videos to perform a qualitative evaluation. Based on analyzing student behavior and the process of students trained in robotics, we found some students show interest in exploring pre-trained ML models and training new models while building personally relevant robotic creations and developing solutions to engineering tasks. While students were interested in using the ML tools for complex tasks, they seemed to prefer to use block programming or manual motor controls where they felt it was practical.

3. Computer Science Principles for Teachers of Blind and Visually Impaired Students

   https://doi.org/10.1145/3287324.3287453  

   Stefik, Andreas ; Ladner, Richard E. ; Allee, William ; Mealin, Sean ( January 2019 , Proceedings Article published 2019 in Proceedings of the 50th ACM Technical Symposium on Computer Science Education - SIGCSE '19)

   The College Board's AP Computer Science Principles (CSP) content has become a major new course for introducing K-12 students to the discipline. The course was designed for many reasons, but one major goal was to broaden participation. While significant work has been completed toward equity by many research groups, we know of no systematic analysis of CSP content created by major vendors in relation to accessibility for students with disabilities, especially those who are blind or visually impaired. In this experience report, we discuss two major actions by our team to make CSP more accessible. First, with the help of accessibility experts and teachers, we modified the entire Code.org CSP course to make it accessible. Second, we conducted a one-week professional development workshop in the summer of 2018 for teachers of blind or visually impaired students in order to help them prepare to teach CSP or support those who do. We report here on lessons learned that are useful to teachers who have blind or visually impaired students in their classes, to AP CSP curriculum providers, and to the College Board.

   The AP Computer Science Principles (CSP) high school course introduces students to computer science and programming. What should motivated students study after successful completion of AP CSP? The AP CSA class teaches Java programming and it has traditionally not attracted students from underrepresented groups. We are working on an alternative, projects-based course that will teach cutting edge CS concepts, such as distributed computing, computer networking, cybersecurity, the internet of things and machine learning, in a hands-on, accessible manner. Such an approach enables students to work on problems that interest them making computing more relevant and the curriculum more engaging. We utilize NetsBlox, a collaborative, block-based programming environment that extends Snap! with a few carefully selected abstractions that open up the vast array of resources freely available on the internet for student programs. Moreover, the tool enables students to work together on the same project remotely similarly to how Google Docs operate. This demonstration will introduce the environment and highlight its utility in creating distributed applications such as a shared whiteboard app and projects that access public domain scientific data sources and visualize them in various ways using online services such as Google Maps or charting. More information is available at https://netsblox.org.

5. The Impact of Pre-Service Teachers’ Perceptions of Engineering on Their Self-Efficacy with Teaching Engineering

   Chesnutt, Betsy ; Mountain, Daniel ; Faber, Courtney ( July 2023 , ASEE annual conference exposition)

   Although engineering is becoming increasingly important in K-12 education, previous research has demonstrated that, similar to the general population, K-12 teachers typically hold inaccurate perceptions of engineering, which affects their ability to provide students with relevant engineering experiences. Studies have shown that K-12 teachers often confuse the work of engineers with that of automotive mechanics or construction workers or assume that engineering is only for “super smart” students who are naturally gifted or who come from higher socioeconomic backgrounds. This indicates that many teachers do not understand the nature of engineering work and have stereotypical attitudes about who is qualified to be an engineer. These inaccurate perceptions of engineering among K-12 teachers may influence the way that teachers introduce engineering practices to their students and make connections between engineering and the other STEM disciplines. In addition, teacher self-efficacy has been shown to not only influence teachers’ willingness to engage with a particular topic, but also to have a significant influence on the motivation and achievement of their students. Research also indicates that high-efficacy teachers typically exert more effort and utilize more effective instructional strategies than low-efficacy teachers. The goal of this study was to examine the perceptions that pre-service K-12 teachers hold about engineers and engineering, and to further explore how those perceptions influence their self-efficacy with teaching engineering and beliefs about what skills and resources are necessary to teach engineering in a K-12 classroom. We first developed a survey instrument that included questions taken from two previously published instruments: the Design, Engineering, and Technology survey and the Teaching Engineering Self-Efficacy Scale for K-12 Teachers. Forty-two students enrolled in an undergraduate program at {Name Redacted} in which students simultaneously pursue a bachelor’s degree in a STEM field and K-12 teacher licensure completed the survey. Based on survey responses, six participants, representing a range of self-efficacy scores and majors, were selected to participate in interviews. In these interviews, participants were asked questions about their perceptions of engineers and were also asked to sort a list of characteristics based on whether they applied to engineers or not. Finally, interview participants were asked questions about their confidence in their ability to teach engineering and about what skills and/or resources they would require to be able to teach engineering in their future classrooms. The results of this study indicated that the participants’ perceptions of engineering and engineers did impact their self-efficacy with teaching engineering and their beliefs about how well engineering could be incorporated into other STEM subjects. A recurring theme among participants with low self-efficacy was a lack of exposure to engineering and inaccurate perceptions of the nature of engineering work. These pre-service teachers felt that they would not be able to teach engineering to K-12 students because they did not personally have much exposure to engineering or knowledge about engineering work. In future work, we will investigate how providing pre-service teachers with training in engineering education and exposure to engineers and engineering students impacts both their perceptions of engineering and self-efficacy with teaching engineering.
