Improving computer science (CS) education in PK-12 continues to be a priority for educators, researchers, and policymakers worldwide. One of the leading problems and mitigating factors of student CS success, however, is the lack of teachers prepared and qualified to teach computer science. Efforts have been made to address this issue through…

In order to create professional development experiences, curriculum materials, and policies that support elementary school teachers to embed computational thinking (CT) in their teaching, researchers and teacher educators must understand ways teachers see CT as connecting to their classroom practices. We interviewed 12 elementary school teachers,…

While research has shown that video can be an effective tool in the professional learning of teachers in industrialized countries, it is unknown whether this is also true for other countries with distinctive cultural, political, and historical contexts, such as Cambodia.

One chronic challenge facing professional development providers is the need to convene and support groups of role-alike K-12 teachers who require similar kinds of discipline-and grade-level-specific training. Online courses have become an increasingly common way to meet this challenge. This article reports on a randomized control trial that tested…

Research shows that unless university-based teacher educators effectively integrate technology into teacher education courses, students (pre-service and in-service teachers) are unlikely to use technology effectively in their own teaching. This creates negative repercussions in teacher education and in the schools. However, many teacher educators…
