The visualization of mathematics education teaching skills is to introduce the theory, technology, and methods of knowledge visualization research into the teaching research field of mathematics education, so as to form a new research direction. By analyzing the status quo of mathematics teaching skill knowledge visualization, and based on summarizing its research characteristics, it described the concepts of mathematics education teaching skill knowledge visualization, discussed its concept features, theoretical basis and expression methods, and summarized its application research status and development trends. The advent of information society has brought the broader space to the cultivation mode of mathematical teaching skills for normal college students. However, the current cultivation of mathematics teaching skills for normal college students is incompatible with the social development, so that many pre-service teachers are less skilled on the mastery and application of teaching skills, which urgent needs to study and adopt the effective ways to accelerate the teaching skill cultivation mode for normal college students, so as to create the teacher team adapt to the social development and with innovative capability [1]. How to reasonably and effectively improve the teaching skills of normal college student? The knowledge has a visualization characteristic, and the teaching skill knowledge visualization is an effective way to help normal college students learn the scientific and stable teaching skills [2]. This article, based on the knowledge visualization theory, described the concepts of mathematics education teaching skill knowledge visualization and discussed its basic characteristics, aiming to explore the effective ways for teaching skill knowledge visualization, thereby providing the theoretical support for the practice of conducting the mathematics teaching skill cultivation for normal college students from a broader perspective.
