In this chapter, the question of whether educational technologies, particularly extended reality technologies, which gained momentum after the pandemic, can serve as an alternative to traditional classrooms in science education was explored. For this aim, an XR workshop has been prepared for middle school science teachers currently teaching in different schools in Duzce, Turkey. During the program, a total of 9 teachers acquired theoretical knowledge about augmented reality, virtual reality, and extended reality, and they also engaged in practical applications. Subsequently, they prepared lesson plans or activities using XR technologies, where they previously applied lessons using traditional methods. At the end of the program, data was collected through interviews with teachers. The views of teachers were discussed in relation to the potential of XR technologies against traditional classrooms.
