   Much of the research on the development of professional noticing expertise has focused on prospective teachers. We contend that we must investigate practicing teachers as well, and in particular practicing secondary teachers, because they bring with them years of teaching experience and are situated in unique contexts. Hence we studied the longitudinal growth of the professional- noticing expertise of a group of practicing secondary teachers (N=10) as they progressed through a 5-year professional development (PD) about being responsive to students’ mathematical thinking. Results indicated that the first half of the PD supported their interpreting and deciding-how-to- respond skills, and the second half of the PD supported their attending skills, which were already strong even before the PD. We compare these results with the activities that occurred in the PD and discuss implications for future research and PD programs.

2. Professional development for STEM departments

   Flowers, L (July 2025, International Journal of Science and Research Archive)

   Professional development is a highly organized and valuable process designed to disseminate specialized knowledge and skills, thereby enhancing workforce efficiency and institutional alignment with the organization's strategic goals and mission. Typically, most professional development resources focus on supporting student retention and career readiness. Maintaining student success and providing programs that enable students to acquire job skills is paramount. However, implementing strong science, technology, engineering, and math (STEM) faculty professional development systems is equally essential to achieving meaningful student outcomes and departmental operational success. Sustainable professional development strategies and faculty support mechanisms must be continually developed, measured, evaluated, and improved to ensure that faculty can meet the needs of STEM majors, the changing educational landscape, and the challenges facing academic institutions. A focus on increased faculty communication from department and executive administration, as well as continuing education opportunities, travel awards, occupational training, mentoring programs, and scholarship initiatives, offers beneficial opportunities to meet faculty professional development needs. The recommendations in this article are intended for STEM faculty but could be adopted for all faculty and modified for STEM department staff.

3. Computer science teacher professional development and professional learning communities: a review of the research literature

   https://doi.org/10.1080/08993408.2021.1993666  

   Ni, Lijun; Bausch, Gillian; Benjamin, Rebecca (October 2021, Computer Science 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.

4. Professional development in 140 characters? Analyzing Twitter as a professional learning platform for science teachers.

   Fischer, C. (January 2018, American Educational Research Association)

   This mixed-methods observational study analyzes Advanced Placement (AP) Biology teachers’ engagement in microblogging for their professional development (PD). Data from three hashtag-based Twitter communities, #apbiochat, #apbioleaderacad, and #apbioleaderacademy (121 users; 2,253 tweets), are analyzed using methodological approaches including educational data mining, qualitative two-cycle content analysis, social network analysis, linear and logistic regression analyses, and hierarchical linear modeling. Results indicate that Twitter adheres to standards of high-quality PD and has the potential to complement more traditional PD activities. Notably, Twitter’s non-hierarchical leadership affords shared content creation and distribution. Additionally, Twitter allows for different temporal participation patterns and supports the personalization of learning experiences aligned to teachers’ needs and preferences. Furthermore, teachers frame their interactions on Twitter positively, thus, creating a supportive environment for professional learning that might reduce teachers’ perceived isolation. Therefore, policy makers and school leaders should feel empowered to encourage teachers to use microblogging complementary to other PD activities.

5. Professional knowledge building within an elementary teacher professional development experience on computational thinking in science education

   Hestness, E; Ketelhut, D. J.; McGinnis, J. R.; Plane, J. (January 2018, Journal of technology and teacher education)

   Abstract. We investigated teacher learning within a professional development (PD) workshop series on computational thinking (CT) for elementary-level mentor teachers. The purpose of the PD was to prepare mentor teachers to support preservice teachers in integrating CT into their classroom practice, toward the broader goal of advancing CT for all in the early grades. We examined the ways in which participants collaboratively built on existing professional knowledge as they engaged in professional learning activities designed to introduce CT and related pedagogies for elementary science education. Our data sources were field notes, artifacts, drawings, written reflections, and focus group interviews. We describe how participants developed new understandings of CT integration and made connections to existing professional knowledge of their students, their curriculum, and their school contexts. We discuss implications for teacher learning and PD design relevant to CT, and make recommendations for future research.
