Exploration of the “3 + 5” Model in Elementary Mathematics Teaching in Smart Classrooms Against a Digital Background—A Case Study

Education digitalization is an inevitable trend of technological development. Based on the theories related to smart classrooms, this research constructs a “3 + 5” teaching model and implements a mixed methods research in Jinshan Elementary School in Chongqing. The “3” in the name refers to three stages of teaching, namely before, during, and after class. The “5” in the name refers to five links of teaching, namely prediction, fine-tuning, detailed explanation, intensive support, and extension. Through questionnaire and interview, it is found that most students and teachers are very satisfied with the “3 + 5” teaching model. The model based on the iFLYTEK smart classroom can accurately locate students’ learning situation, improve classroom efficiency, develop personalized learning plans, and provide data support for the digital transformation of primary school mathematics.
