 In traditional writing teaching, students lack the experience and perception of real context, and the simulated learning environment created by Spherical Video-based Virtual Reality (SVVR) can create an immersive 3D simulation environment with multiple perceptual characteristics for students, and support students' participation enthusiasm and improvement of writing literacy. Therefore, by adopting quasiexperimental research and incorporating the concept of double-cycle teaching, this paper randomly divided 97 fifth-grade primary school students into the experimental group and the control group, and 
carried out writing learning activities in SVVR and PPT learning environments respectively. The lag sequence analysis method was used to explore the differences of classroom interaction between teachers and students in different learning environments. The results show that writing learning environment based on SVVR can promote students' classroom interaction, promote students' active expression and peer feedback, and improve students' independent thinking ability. The integration of the double-cycle teaching concept further promotes the application of SVVR in writing class, and makes the teaching mode and teaching technology improve together.
