Abstract: This study focuses on the portrayal of laborers in the 2019 People’s Education Press Version A high school mathematics textbooks, analyzing them from four aspects: distribution, characteristic attributes, methods of portrayal, and educational functions. The findings are as follows: The distribution of laborer images in the textbooks has a clear carrier orientation, primarily concentrated in sections such as example problems and exercises. In terms of natural and social attributes, the portrayal of laborers exhibits distinct characteristics of occupational stereotypes. In terms of methods of portrayal, static descriptions are predominantly used, with a heavy reliance on textual representation and insufficient interactivity, resulting in limited emotional impact. Regarding educational functions, the emphasis is on the application of mathematical knowledge, while elements such as the demonstration of labor spirit and vocational education value are inadequate. Based on these findings, the following teaching implications are proposed for mathematics teachers: deeply explore the portrayal of laborers in mathematics textbooks and revitalize their teaching representation; reconstruct the role spectrum of occupational attributes of laborers in mathematics textbooks; employ multi-modal approaches to enhance the portrayal and emotional impact of laborers in mathematics textbooks; and leverage the portrayal of laborers in textbooks to develop a teaching model that integrates emotion and knowledge.
