The rapid development of digitalization in education is gradually changing the traditional teaching mode, especially in the field of art education, this transformation is more and more significant. This paper delves into the practical application of graphology algorithms in children’s ink painting courses in higher teacher training colleges in an attempt to enhance students’ artistic creation ability and teachers’ teaching level through innovative digital teaching methods. This paper proposes an innovative teaching platform, which uses graphology algorithms to simulate the changes of ink strokes and ink colors in ink painting, and seeks to realistically reproduce the artistic effects of traditional ink painting in a digital environment. Through this approach, students are able to intuitively perceive and master the skills of ink painting creation in a virtual teaching environment, thus stimulating their learning interest and artistic expression. Empirical studies have shown that this teaching method based on digital means has not only achieved remarkable results in improving students’ artistic expression, but also effectively enhanced their learning motivation. At the teacher level, the construction of the relevant training system has also been widely praised, and the teachers’ professionalism and teaching ability have been significantly improved. The research in this paper not only provides strong support for the theory of digital transformation of education, but also guides the direction of modernization and reform of children’s ink painting curriculum, which is of great significance in promoting the digital development of art education in China.
