   People typically learn programming from teachers in in-person courses or online tutorials. Interactive computer tutors---systems that deliver learning content interactively---have become more prevalent in online settings for teaching skills such as computer programming. Research has shown the efficiency and effectiveness of learning programming from teachers, interactive computer tutors, and a combination of both. However, there is limited understanding of learners' comparative perspectives about their experience learning from these different resources. We conducted an exploratory study using semi-structured interviews, recruiting 20 participants that had experience learning programming from both teachers and interactive computer tutors. We identified factors that learners like and dislike from both learning methods and discussed the strengths and weaknesses of them. Based on our findings, we propose suggestions for designers of interactive computer tutors, and for programming educators.

2. Developing Empathy and Persistence through Professional Development in New to CSA Teachers

   To meet the rising demand for computer science (CS) courses, K-12 educators need to be prepared to teach introductory concepts and skills in courses such as Computer Science Principles (CSP), which takes a breadth-first approach to CS and includes topics beyond programming such as data, impacts of computing, and networks. Educators are now also being asked to teach more advanced concepts in courses such as the College Board's Advanced Placement Computer Science A (CSA) course, which focuses on advanced programming using Java and includes topics such as objects, inheritance, arrays, and recursion. Traditional CSA curricula have not used content or pedagogy designed to engage a broad range of learners and support their success. Unlike CSP, which is attracting more underrepresented students to computing as it was designed, CSA continues to enroll mostly male, white, and Asian students [College Board 2019, Ericson 2020, Sax 2020]. In order to expand CS education opportunities, it is crucial that students have an engaging experience in CSA similar to CSP. Well-designed differentiated professional development (PD) that focuses on content and pedagogy is necessary to meet individual teacher needs, to successfully build teacher skills and confidence to teach CSA, and to improve engagement with students [Darling-Hammond 2017]. It is critical that as more CS opportunities and courses are developed, teachers remain engaged with their own learning in order to build their content knowledge and refine their teaching practice [CSTA 2020]. CSAwesome, developed and piloted in 2019, offers a College Board endorsed AP CSA curriculum and PD focused on supporting the transition of teachers and students from CSP to CSA. This poster presents preliminary findings aimed at exploring the supports and challenges new-to-CSA high school level educators face when transitioning from teaching an introductory, breadth-first course such as CSP to teaching the more challenging, programming-focused CSA course. Five teachers who completed the online CSAwesome summer 2020 PD completed interviews in spring 2021. The project employed an inductive coding scheme to analyze interview transcriptions and qualitative notes from teachers about their experiences learning, teaching, and implementing CSP and CSA curricula. Initial findings suggest that teachers’ experience in the CSAwesome PD may improve their confidence in teaching CSA, ability to effectively use inclusive teaching practices, ability to empathize with their students, problem-solving skills, and motivation to persist when faced with challenges and difficulties. Teachers noted how the CSAwesome PD provided them with a student perspective and increased feelings of empathy. Participants spoke about the implications of the COVID-19 pandemic on their own learning, student learning, and teaching style. Teachers enter the PD with many different backgrounds, CS experience levels, and strengths, however, new-to-CSA teachers require further PD on content and pedagogy to transition between CSP and CSA. Initial results suggest that the CSAwesome PD may have an impact on long-term teacher development as new-to-CSA teachers who participated indicated a positive impact on their teaching practices, ideologies, and pedagogies.

3. Translating and Scaling a Face-to-Face, Video-Based Elementary Science PD Program to an Online Environment

   Kowalski, S.; Belcastro, A.; Hvidsten, C.; Constantine, A.; Faruqi, F.; Askinas, K.; De Vaul, R.; Roehrig, G. (April 2021, Annual Meeting of the NARST International Conference)

   Objective Over the past decade, we developed and studied a face-to-face video-based analysis-of-practice professional development (PD) model. In a cluster randomized trial, we found that the face-to-face model enhanced elementary science teacher knowledge and practice and resulted in important improvements to student science achievement (student treatment effect, d = 0.52; Taylor et al, 2017; Roth et al, 2018). The face-to-face PD model is expensive and difficult to scale. In this paper, we present the results of a two-year design-based research study to translate the face-to-face PD into a facilitated online PD experience. The purpose is to create an effective, flexible, and cost-efficient PD model that will reach a broader audience of teachers. Perspective/Theoretical Framework The face-to-face PD model is grounded in situated cognition and cognitive apprenticeship frameworks. Teachers engage in learning science content and effective science teaching practices in the context in which they will be teaching. There are scaffolded opportunities for teachers to learn from analysis of model videos by experienced teachers, to try teaching model units, to analyze video of their own teaching efforts, and ultimately to develop their own unit, with guidance. The PD model attends to the key features of effective PD as described by Desimone (2009) and others. We adhered closely to the design principles of the face-to-face model as described by Authors, 2019. Methods We followed a design-based research approach (DBR; Cobb et al., 2003; Shavelson et al., 2003) to examine the online program components and how they promoted or interfered with the development of teachers’ knowledge and reflective practice. Of central interest was the examination of mechanisms for facilitating teacher learning (Confrey, 2006). To accomplish this goal, design researchers engaged in iterative cycles of problem analysis, design, implementation, examination, and redesign (Wang & Hannafin, 2005) in phase one of the project before studying its effect. Data Three small pilot groups of teachers engaged in both synchronous and asynchronous components of the larger online course which began implementation with a 10-week summer course that leads into study groups of participants meeting through one academic year. We iteratively designed, tested, and revised 17 modules across three pilot versions. On average, pilot groups completed one module every two weeks. Pilot 1 began the work in May 2019; Pilot 2 began in August 2019, and Pilot 3 began in October 2019. Pilot teachers responded to surveys and took part in interviews related to the PD. The PD facilitators took extensive notes after each iteration. The development team met weekly to discuss revisions. We revised all modules between each pilot group and used what we learned to inform our development of later modules within each pilot. For example, we applied what we learned from testing Module 3 with Pilot 1 to the development of Module 3 for Pilots 2, and also applied what we learned from Module 3 with Pilot 1 to the development of Module 7 for Pilot 1. Results We found that community building required the same incremental trust-building activities that occur in face-to-face PD. Teachers began with low-risk activities and gradually engaged in activities that required greater vulnerability (sharing a video of themselves teaching a model unit for analysis and critique by the group). We also identified how to contextualize technical tools with instructional prompts to allow teachers to productively interact with one another about science ideas asynchronously. As part of that effort, we crafted crux questions to surface teachers’ confusions or challenges related to content or pedagogy. We called them crux questions because they revealed teachers’ uncertainty and deepened learning during the discussion. Facilitators leveraged asynchronous responses to crux questions in the synchronous sessions to push teacher thinking further than would have otherwise been possible in a 2-hour synchronous video-conference. Significance Supporting teachers with effective, flexible, and cost-efficient PD is difficult under the best of circumstances. In the era of covid-19, online PD has taken on new urgency. NARST members will gain insight into the translation of an effective face-to-face PD model to an online environment.

4. School-embedded and district-wide instructional coaching in K-8 computer science: Implications for including students with disabilities

   Israel, M.; Ray, M. J.; Maa, W. C.; Jeong, G.; Lee, C.; Lash, T.; & Do, V. (January 2018, Journal of technology and teacher education)

   As school districts implement initiatives that bring computer science (CS) to academically diverse K-12 schools, they face heightened demands for supporting teachers in meeting the needs of a broad range of learners. However, limited knowledge exists about pedagogical approaches to teaching CS, especially to students with disabilities. This paper reports findings from a qualitative study of two CS instructional coaching models meant to support teachers in meeting the needs of diverse learners, including those with disabilities. One model involved a school-embedded coach and the other model involved a district-wide coach that traveled among multiple schools. Findings revealed that within both coaching models, co-planning and co-teaching played an integral role in supporting teachers in meeting the needs of students with disabilities. Instructional pedagogies that coaches promoted included scaffolded project planning, student collaboration, and immediate feedback to students. Within both coaching models, there was a focus on trust building and increasing teachers’ instructional skills. Differences between coaching models included a stronger level of familiarity between the coach and teachers in the school-embedded coaching. There were also different approaches to accountability and co-planning logistics.

5. A Socially Relevant Focused AI Curriculum Designed for Female High School Students

   https://doi.org/10.1609/aaai.v36i11.21546  

   Alvarez, Lauren; Gransbury, Isabella; Cateté, Veronica; Barnes, Tiffany; Lédeczi, Ákos; Grover, Shuchi (June 2022, Proceedings of the AAAI Conference on Artificial Intelligence)

   Historically, female students have shown low interest in the field of computer science. Previous computer science curricula have failed to address the lack of female-centered computer science activities, such as socially relevant and real-life applications. Our new summer camp curriculum introduces the topics of artificial intelligence (AI), machine learning (ML) and other real-world subjects to engage high school girls in computing by connecting lessons to relevant and cutting edge technologies. Topics range from social media bots, sentiment of natural language in different media, and the role of AI in criminal justice, and focus on programming activities in the NetsBlox and Python programming languages. Summer camp teachers were prepared in a week-long pedagogy and peer-teaching centered professional development program where they concurrently learned and practiced teaching the curriculum to one another. Then, pairs of teachers led students in learning through hands-on AI and ML activities in a half-day, two-week summer camp. In this paper, we discuss the curriculum development and implementation, as well as survey feedback from both teachers and students.
