Mathematical modelling ability is one of the important core qualities of mathematics, and its development tends to be affected by non-intelligence factors. To understand the relationship between motivation, emotion, will, attitude and character of senior school students and mathematical modelling ability, this paper conducts a survey of 202 students in two senior schools. The derived findings reveal that the non-intelligence factors of senior school students are generally at the "medium" level and are of a significant correlation with mathematical modelling ability. Some suggestions are provided to stimulate their learning motivation of mathematical modelling so that students can produce good emotions to regulate and maintain their long-term learning activities of mathematical modelling.
