The increasing number of technological devices available in schools, aligned with curriculum guidance, set an expectation for mathematics teachers to incorporate these devices into their teaching. This qualitative study investigated prospective teachers' use of TPACK and mathematical action technologies as they created screencast video lessons using iPads. Results showed prospective teachers' effective use of pedagogical techniques and the screencast app as an amplifier tool, according to the amplifier-reorganizer metaphor. Half of the participants used mathematics technology to confirm and expand the results they had found without technology. The other half had mathematics technology integrated into their solution exercising the balance among TPACK components. For some, their use of the mathematical tool had the potential of expanding the mathematical repertoire of virtual students. We conclude by making recommendations for teacher educators to implement cycles of learning for pre-service teachers to design, enact, and reflect upon the creation of screencast video lessons.

学校里可用的技术设备数量不断增加,与课程指导相一致,这使得人们期望数学教师将这些设备融入教学中。这项定性研究调查了职前教师在使用iPad创建屏幕录制视频课程时对TPACK和数学行动技术的运用。结果表明,根据放大器 - 重组器隐喻,职前教师有效地运用了教学技巧,并将屏幕录制应用程序用作放大器工具。一半的参与者使用数学技术来确认和扩展他们在没有技术帮助时所获得的结果。另一半则将数学技术融入他们的解决方案中,实现了TPACK各组成部分之间的平衡。对于一些人来说,他们对数学工具的使用有可能扩展虚拟学生的数学技能。我们最后为教师教育工作者提出建议,为职前教师实施学习循环,以便他们设计、实施并反思屏幕录制视频课程的创建过程。
