This study investigates the factors influencing interactive teaching decision-making level among novice music teachers in junior high schools, a fundamental skill that spans the entire music teaching process. Focusing on classroom instruction and student learning, the study addresses two primary questions: (1) What factors affect the interactive teaching decision-making of novice music teachers? (2) How do these factors vary by gender, educational background, and teaching experience? A questionnaire survey of novice music teachers in Boshan, China, was conducted, and the collected data were analyzed using SPSSAU software. The findings indicate that student response is the most influential factor, while evaluation is the least. Comparative analysis shows that novice teachers with 2-3 years of teaching experience rank higher in classroom resilience and teaching skills, whereas those with 0-2 years score higher in classroom management. Nonparametric statistics further illuminate differences in interactive decision-making by teaching experience. The study suggests that novice music teachers should prioritize student responses, enhance classroom resilience and teaching skills, and emphasize classroom evaluation and reflection. These insights aim to improve decision-making processes and support the professional development of novice music teachers.
