With the deepening of educational informatization, the classroom interaction model has transformed from the original one-way indoctrination teaching to the current multi-dimensional, dynamic, interactive teaching. This paper mainly studies the specific application and in-depth reflection of information-based teaching tools in classroom interaction, attempting to explore the reconstruction mechanism of teacher-student interaction and student-student interaction after technological empowerment. The article first discusses how tools break through the constraints of time and space to activate the classroom ecology, then analyzes how data-driven, precise feedback improves teaching strategies, and finally explores the risk of “technological alienation” and the path of humanistic return in the process of technology application. Through theoretical deduction and logical construction, this paper attempts to provide theoretical support and practical direction for a new type of intelligent, efficient and warm classroom.
