This study describes a professional development (PD) program designed to support middle school teachers in effectively integrating robotics in science and mathematics classrooms. The PD program encouraged the teachers to develop their own science and mathematics lessons, aligned with national standards, infused with robotic activities. A multi-week summer PD and sustained academic year follow-up imparted to the teachers the technical knowledge and skills of robotics as well as an understanding of when and how to use robotics in science and mathematics teaching. The goal of this study is to investigate the effects of the robotics-integrated PD program through the changes of teachers’ technological-pedagogical-and-content knowledge self-efficacy, the improvement in their content knowledge of robotics in the context of science and mathematics teaching, and their reflections on the PD. The 41 participants consisted of 20 mathematics and 20 science teachers and one teacher who teaches both subjects. Three instruments were administered to the teachers during the PD, and follow-up interviews were conducted to further examine benefits and possible impacts on their teaching resulting from the PD. The data were analyzed by both statistical and qualitative methods to identify the effectiveness of the PD. The findings of the study indicate that the PD program was effective in increasing participants’ robotics content knowledge and confidence and outcome expectancy while integrating robotics in their teaching practices. Based on teacher reflections and follow-up interviews, this study offers guidelines for future development of technology-integrated science and mathematics teaching.

这项研究描述了一个专业发展（PD）计划，旨在支持中学教师有效地将机器人技术整合到科学和数学课堂中。PD计划鼓励教师开发自己的科学和数学课程，以符合国家标准并注入机器人活动。为期数周的夏季PD和持续的学年随访向教师传授了机器人技术知识和技能，并了解了何时以及如何在科学和数学教学中使用机器人。这项研究的目的是通过改变教师的技术教学和内容知识的自我效能来研究机器人集成的PD计划的效果，在科学和数学教学的背景下，他们对机器人技术的内容知识的改进，以及对PD的思考。41位参与者包括20位数学和20位理科老师，以及一位同时教授这两个学科的老师。在PD中对教师使用了三种工具，并进行了后续访谈，以进一步检查PD对教师的益处和可能产生的影响。通过统计和定性方法对数据进行分析，以确定效绩数据的有效性。研究结果表明，PD计划有效地提高了参与者的机器人知识，并在将机器人技术融入其教学实践的同时，提高了他们的信心和预期结果。根据老师的反思和后续访谈，
