A grand challenge of the computer science (CS) for all education movement is the preparation of thousands of teachers with high quality, accessible professional development (PD) that has evidence of improving teacher knowledge and pedagogical practices necessary to support the learning needs of diverse groups of students. While regional PD programs can provide in-person learning opportunities, geographic and time constraints often inhibit participation. This article shares findings from an online PD program modified from the existing in-person exploring computer science PD program to provide teachers a facilitated online learning community model to support their first year teaching the course. The findings from this study have implications for future directions in the CS education field, indicating that this model of online PD, heavily based on shared experience among participants, can increase CS teachers’ confidence in adapting and delivering lessons designed to be engaging and accessible to all students.

高中计算机科学教师的在线专业发展：支持基于公平的专业学习社区的功能

计算机科学 (CS) 对所有教育运动的一个巨大挑战是为数以千计的教师提供高质量、可访问的专业发展 (PD) 的准备，这些教师有证据证明提高教师知识和教学实践，以支持不同群体的学习需求学生的。虽然区域 PD 计划可以提供面对面的学习机会，但地理和时间限制通常会阻碍参与。本文分享了在线 PD 计划的发现，该计划从现有的亲自探索计算机科学 PD 计划修改而来，为教师提供便利的在线学习社区模型，以支持他们第一年教授课程。这项研究的结果对 CS 教育领域的未来方向具有影响，表明这种在线 PD 模型，
