As educational technology advances, traditional teaching models no longer fully meet the learning needs of contemporary high school students. More educators are recognizing that strong learning motivation can inspire positive learning attitudes in students, and robust enthusiasm for learning can significantly improve learning outcomes. This is particularly true for mathematics, a subject that heavily involves abstract thinking, where students’ motivation levels are typically moderate to low. Thus, stimulating students’ learning motivation has become an indispensable issue in educational activities. Through the analysis of the ARCS motivation model and integrating specific teaching practices to refine and adjust the model’s four aspects, this paper aims to assist educators in enhancing teaching effectiveness and boosting students’ interest in learning.
