This article explores how the practice-focused Studio professional learning (PL) model can provide incremental and ambitious teacher learning opportunities. We argue that when the model’s structures and practices are grounded in ambitious and equitable teaching, they catalyze incremental teacher learning. Studio, like lesson study, supports teachers in considering the entailments of lessons, focusing on the live shared enactment to strengthen teaching and learning through collaborative analysis and reflection. To build our argument, we drew from two Studio projects that had shared structures of cycles of learning and routines, as well as shared practices of using rich representations and collective interpretations of teaching. While both projects’ structures and practices take up ambitious and equitable teaching, they use different routines and attend to different features of equitable teaching. Building on a history of PL models, such as lesson study, which use similar structures and practices as powerful catalysts of teacher learning, we argue that Studio’s structures and practices can catalyze teachers’ incremental learning of ambitious and equitable teaching. We discuss the implications for future research based on this argument and for those leading PL.

                            Using Visual Representations: How using visual representations may provide teacher leaders with a tool for supporting sustained teacher learning
                        
                    
    
            This paper highlights two teachers that participated in two different professional development (PD) experiences who sustained new teaching practices and learning five years after participating. Both PD projects focused on visual representations (VRs) and encouraged and modeled ambitious teaching practices. Teachers provided video clips and participated in interviews to illustrate and describe changes that took place in their learning and practice. Our qualitative analysis showed that (1) the teachers’ use of VRs appears to be strongly connected to teachers' own active learning of VRs in PD, (2) VRs appears to be a key factor that supported the teachers’ use of other ambitious teaching practices in their classroom and (3) that the two teachers remembered and continued to use ambitious practices and VRs in their classrooms in ways that not only aligned to the goals and intention of the PD, but also adapted and extended representations to different mathematical domains and settings. Implications for mathematics education leaders suggest that a focus on VRs may be one tool to anchor learning to deepen teachers’ abilities to engage in ambitious teaching practices.

            Chinn, C.; Tan, E.; Chan, C.; Kali, Y. (Ed.)Effective teaching relies on practices of reflection and inquiry that must be cultivated throughout teachers’ careers. Professional development (PD) can support those practices by positioning participants to develop and build on insights. Using data from a PD program focused on teacher noticing for equity, we draw on practice theory to identify the process and associated practices that emerged through participation in collaborative inquiry. Analysis reveals three phases of activity, consisting of interrelated practices that drove insight-based learning: building awareness, collaborative exploration, and learning through design. Through engaging in this process, participants made unconscious aspects of teaching visible that allowed participants to deepen and expand their insights, and through design, articulated new insights and situated their learning back in the context of their teaching. These findings have implications for designing PD that prioritizes participants’ agency to cultivate practices of reflection and inquiry.more » « less

            null (Ed.)One way to support teachers' learning to facilitate the recent reform vision (NRC, 2012) in their classrooms is through professional development (PD). We explored a biology teacher’s (Monica) sensemaking during the PD that focused on facilitating productive science classroom discourse to understand her responses to the PD in terms of teaching science by engaging students in productive talk in science classrooms. Using both video and interview data, we analyzed the process of her sensemaking about facilitating (productive) talk during the PD and the meaning she was making of productive talk. Our analysis indicated that Monica participated in sensemaking mostly about her students' participation in talk. Throughout the PD conversations, she rarely focused on what she could do (or could have done) to facilitate student talk without the PD facilitators' pressing. This is supported by our analysis of the interviews with Monica, which showed that the sense that she was making about productive talk mostly focuses on students' contributions to the talk and their accountability to reasoning, scientific knowledge, and sensemaking. These findings provide implications for facilitating teachers’ sensemaking around new instructional practices and reforms within PD contexts.more » « less

            Teacher self-efficacy (SE) has been observed to be an 'important construct for Computer Science (CS) teachers' professional development because it can predict both teaching behaviors as well as student outcomes" [1]. The purpose of the present study was to investigate teacher CS SE during a two-year federally funded professional development (PD) and curriculum development project for middle school teachers incorporating game-design and the Unity development platform. The research question investigated is: How does teacher self-efficacy for teaching computer science via game design with the Unity game development platform change during a year-long PD program? Investigations of teacher SE for teaching CS have resulted in some surprising results. For example, it has been reported that - There were no differences in self-efficacy based on teachers' overall level of experience, despite previous findings that teacher self-efficacy is related to amount of experience" and "no differences in self-efficacy related to the teachers' own level of experience with CS" [2], thus further study of CS teacher SE is warranted. Participants in this study were six middle school teachers from four middle schools in the southeastern United States. They participated in a year-long PD program learning the Unity game development platform, elements of game design, and foundations of learner motivation. Guided reflective journaling was used to track the teachers' SE during the first year of the project. Teachers completed journal prompts at four intervals. Prompts consisted of questions like "How do you currently feel about your ability to facilitate student learning with Unity?" and "Are you confident that you can implement the materials the way the project team has planned for them to be implemented?" Prior to beginning the project participants expressed confidence in being able to facilitate student learning after participating in the planned professional development, but there was some uneasiness about learning and using Unity. From a SE perspective their responses make sense, as all of the participants are experienced teachers and should have confidence in their general ability to teach. However, since Unity is a new programming environment for all of the teachers, they did not have the prior experience necessary to have a high degree of confidence that they could successfully use it with their students.more » « less

            null (Ed.)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.more » « less
