The exploration and practice of R drawing guidance model for the promotion of programming teaching for the pratacultural science majors

Under the background of the biological big data era, it is of great practical significance to enhance the comprehensive quality and scientific research ability of students of pratacultural science majors to use programming language for big data processing and visual analysis. However, there are still many problems such as insufficient attention and poor teaching effect in the cultivation of the programming ability of non-computer majors in China. How to guide students to construct a programming knowledge system quickly is one of the main problems in the course reform of informatics in colleges and universities. The author based on years of experience in teaching and research practice, focus on the key problems, such as students' weak foundation in programming and learning interest, from the aspects of teaching guidance, learning content, teaching mode and in-depth learning mechanism, put forward a new programming teaching mode to help students of pratacultural science and other biology majors learning to program with R language-based drawing as guidance. Practice shows that this teaching model can effectively overcome students' fear of programming, stimulate students' potential and interest in programming learning, effectively improve the teaching quality and effect, and will lay a good foundation for students to independently study programming in the future.
