On the afternoon of August 23rd, "202 1" was held in the second staircase classroom of Dayi Vocational High School. This training was given by Huang Jing, the head of mathematics teaching and research group of Sichuan Tianfu New District Vocational School, and all mathematics teachers participated. First of all, as the host of this training, Mr. Zheng Lei introduced the lecturer of this training, Mr. Huang Jing, to the participating teachers.

I also hope that all participating teachers can be inspired by this training and improve their self-study ability. Then, according to her own teaching experience, Huang Jing shared with you in detail how to improve the teaching ability of math teachers in vocational high schools. The difficulty of mathematics is not only memorizing formulas, but also stimulating students' spatial imagination.

In order to better understand the geometric problems, Mr. Huang first summarized the whole vocational education examination syllabus and test sites, and then emphatically introduced the modern teaching tool-3D drawing software, which intuitively showed the spatial turning changes of geometric figures and the relationship between tangency and intersection. Teacher Huang told the teachers that teaching should take into account students' continuous learning needs and their practical ability.

Improve students' interest in mathematics learning. At the same time, as a teacher, we should not only sort out the key points of mathematics chapters in vocational high schools, but also analyze the types of questions in ordinary high schools in order to improve the teaching quality of teachers.
