K-12 teachers and students are vulnerable to cybersecurity attacks and mostly ill-prepared to deal with them. The COVID-19 pandemic has only increased these risks because of the reliance on digital technology in education and increased free time young children and adolescents spend online. Simultaneously, the U.S. is facing an extreme shortage of…

Despite repeated warnings from K-12 online learning scholars, media, and U.S. government bodies about the need for teacher readiness in the face of school disruptions like COVID-19, teacher education programs have largely fallen short in preparing educators for effective online and blended teaching during extended school closures. In this paper,…

Teacher technology professional development (PD) is seen as an important component of meeting the vision for technology use in schools. This study continues Lawless and Pellegrino's (2007) work by examining which characteristics of teacher technology PD were associated with growth in teachers' technology practices and student outcomes. The…

Indigenous communities remain among the most underrepresented groups in computing and STEM fields, facing systemic barriers to equitable participation in computer science (CS) education. This study examines how Indigenous-serving teachers, through a sustained professional development (PD) program, design and implement culturally responsive…

As both educational technology and Communities of Practice (CoPs) have become more established in schools globally, it is unsurprising that they have been employed together to improve teachers' practice. The creation of collaborative professional learning groups to support the use of educational technology in the classroom has been explored in…

Teachers, support staff, schools, and school districts have faced a multitude of challenges in adapting their known and familiar practices to the new realities and restrictions that have been put in place due to the outbreak of COVID-19. These challenges are daunting and difficult for many in our education system. Fortunately, a numerous amount of…

Teacher preparation programs have been slow to answer calls to prepare teachers for the online learning environment, leaving many online teachers needing to learn on the job. However, little research has examined how online teachers grow as educators while teaching online. One way to better understand this growth is to examine the changes online…

Computational Thinking (CT) is an increasingly relevant concept that researchers are promoting in formal learning contexts. In their mission to prepare teachers to integrate CT into K-12 schooling, teacher educators would benefit from understanding the different kinds of preconceptions of CT that their students bring to the classroom in order to…

The field of computer science continues to lack diverse representation from women and racially minoritized individuals. One way to address the discrepancies in representation is through systematic changes in computer science education from a young age. Pedagogical and instructional changes are needed to promote meaningful and equitable learning…

P. K. Yonge Development Research School (PKY) is a single-school, K-12, public school district and "Virtually PKY" is the name of our efforts during emergency remote teaching necessitated by COVID-19. Our ability to plan and execute "Virtually PKY" was predicated on years of district-wide leadership and professional learning…

The unforeseen school closures in response to COVID-19 have brought unique challenges to teachers, who were required to not only flexibly shift between on- and off-line learning but also safely promote student-centered and collaborative learning in socially distanced remote and on-campus classrooms. Teachers in South Korea, one of the first…

This paper reports findings from a study that followed K-12 mathematics teachers through the components of a blended professional development program, highlighting their engagement in a series of online modules that connect face-to-face gatherings across the school year. Data collected over four years illuminate the teachers' performance,…

Lesson study is a professional development activity that increases teachers' attention to student thinking. However, coordinating teachers' live observations of a lesson can be challenging. Using the framework of "distributed cognition," we investigate whether technology supports teachers' examination of student thinking and aids the…

Understanding the dynamics of individual or group adaptation can provide valuable information for constructing professional development strategies to increase chances of instructional success. This paper reports on an exploratory study that identifies indicators of convergent vs. non-convergent adaptation in two cases of teachers working together…

The Arctic Climate Modeling Program (ACMP) offered yearlong science, technology, engineering, and math (STEM) professional development to teachers in rural Alaska. Teacher training focused on introducing youth to workforce technologies used in Arctic research. Due to challenges in making professional development accessible to rural teachers, ACMP…
