Effective professional learning communities (PLCs) are important in supporting teacher learning. This study investigated computer science (CS) teacher leaders’ perspectives on the lessons and the challenges in supporting CS teachers through local PLCs. We purposefully selected ten CSTA chapters and conducted focus group interviews with the chapter leaders between 2020 and 2022. Our findings indicated that these PLCs offered social-emotional support, continual networking opportunities, and rich professional learning resources. Also, they amplified teachers’ voices and supported CS teachers’ professional identity building. To engage CS teachers, the teacher leaders built trust, collaborated with other PLCs or organizations, and set an inclusive PLC culture. These PLCs had challenges in recruitment, leadership development and transition, and building group identity. 

This paper examines the use of collaborative curriculum design (co-design) as a strategy for supporting teacher professional learning and the implementation of an inclusive middle school computer science and digital literacy (CSDL) curriculum in three urban school districts. The curriculum is focused on students developing mobile apps that provide social and community good. The second year of the project has been dedicated to developing and piloting curriculum resources that support remote learning and culturally relevant pedagogy while the partner districts switched to remote and hybrid instructions. This study explores teachers’ professional learning experiences in the collaborative design of curriculum materials and piloting the curriculum at their own classrooms. The paper includes analysis of three data sets: (1) co-design meeting notes and teacher reflections; (2) semi-structured interviews with teachers who co-designed and piloted the curriculum; (3) student pre- and post-survey responses on their attitude and interest in learning CSDL. Preliminary results indicate that the co-design approach supplemented with one-on-one coaching has not only facilitated the curriculum development process but also fostered professional learning and collective capacity building for implementing the project curriculum in the partner districts. Findings from student surveys show that students perceived their understanding of, and interest in computer science and creating apps were slightly improved, regardless of gender. 

The recent pandemic has resulted in challenges to the prioritization of CS curriculum and strained the structures that support and grow the professional development and identity building of the teachers who implement it. In this poster we examine how local chapters of a national CS teacher advocacy organization (the CSTA) support their members during a time of transition and change. Using focus group data collected from an ongoing multi-year longitudinal research project, we tried to better understand the challenges that these entities faced as their normal structures of communication and outreach were closed off, and how such challenges might affect the perceptions of the role that local chapters play in supporting the continued development of their members, including their identity as CS teachers. 

This poster shares our experience of engaging middle school teachers in a collaborative design of a computer science and digital literacy (CSDL) curriculum through a researcher and practitioner partnership (RPP) among two public universities and three urban school districts in the Northeast USA. The project used the co-design approach to facilitate curriculum development and foster professional learning. In this poster, we introduce the co-design process, the developed curriculum, and teachers' professional learning experiences. Preliminary results indicate that the co-design approach supplemented with one-one-on coaching has not only facilitated the curriculum development but also fostered professional learning and collective capacity building for CS education. 

Background & Context: Many efforts have been dedicated to building computer science (CS) teacher capacity through offering professional development (PD) programs. Previous reviews indicated the need to offer more continual support for teachers. Recent research has shifted its focus to scaling up PD and sustaining teaching capacity by establishing PLCs for CS teachers. Objective: This study aims to conduct a systematic literature review of recent research on K-12 CS teacher PD, with an explicit exploration of PLCs. Method: Based on 48 selected articles of 41 programs, this study explored features that contributed to the effectiveness of PD, including (1) PD goals, (2) theoretical frameworks and PD models, (3) curriculum and pedagogy, (4) programming tools, (5) program structure and approach, and (6) PD evaluation. We also examined whether and how these programs were dedicated to establishing PLCs. Findings: Findings indicate a considerable increase in the number of studies on CS teacher PD. More programs saw the promising roles of PLCs and explored a variety of approaches for community building and promoting teacher learning. Implications: PLCs have immense potential for teacher development, including breaking teacher isolation and fostering collaboration. More research can enlighten the efforts for CS teacher preparation and development. 

Motivation: Recent efforts to expand K-12 computer science education highlight the great need for well-prepared computer science (CS) teachers. Teacher identity theory offers a particular conceptual lens for us to understand computer science teacher preparation and professional development. The emerging literature suggests that teacher identity is central to sustaining motivation, efficacy, job satisfaction, and commitment, and these attributes are crucial in determining teacher retention. While the benefits associated with a strong sense of teacher identity are great, teachers face unique challenges and tensions in developing their professional identity for teaching computer science. Objectives: This exploratory study attempts to operationalize computer science teacher identity through discussing the potential domains, proposing and testing a quantitative instrument for assessing computer science teachers’ professional identity. Method: We first discussed the potential domains of computer science teacher identity based on recent teacher identity literature and considerations on some unique challenges for computer science teachers. Then we proposed the computer science teacher identity scale, which was piloted through a national K-12 computer science teacher survey with 3,540 completed responses. The survey results were analyzed with a series of factor analyses to test the internal structure of the computer science teacher identity scale. Results: Our analyses reveal a four-factor solution for the computer science teacher identity scale, which is composed of CS teaching commitment, CS pedagogical confidence, confidence to engage students, and sense of community/belonging. There were significant differences among the teachers with different computer science teaching experiences. In general, teachers with more computer science teaching experience had higher computer science teacher identity scores on all four factors. Discussion: The four-factor model along with a large national dataset invites a deeper analysis of the data and can provide important benchmarks. Such an instrument can be used to explore developmental patterns in computer science teacher identity, and function as a pedagogical tool to provoke discussion and reflection among teachers about their professional development. This study may also contribute to understanding computer science teachers’ professional development needs and inform efforts to prepare, develop, and retain computer science teachers. 

This pilot study explores the impact of the CS Pathways professional development (PD) program on the teachers' self-efficacy in teaching a middle school computer science and digital literacy (CSDL) curriculum. The main goal of the study is to investigate the attributes that describe the teachers' self-efficacy after their first-year participation in the PD. A total of 19 middle school teachers from two states, NY and MA, attended the CS Pathway PD program and completed the end-of-year survey pertaining to self-efficacy in CSDL; more than half accepted the interview to help further understand their perceptions (n=10). Principal Component Analysis (PCA) is applied to study the attributes of the teachers' self-efficacy. The preliminary results capture teachers' self-efficacy patterns, which inform the PD and indicate its effectiveness and challenges.
