Exploration of blended teaching mode based on Citespace visualization analysis in vocational schools

In recent years, vocational education has gained increasing importance. Secondary school students' basic knowledge is weak, low motivation to learn. Changing the teaching model is undoubtedly one of the best ways to improve the quality of secondary vocational education. In this paper, we use Citespace to analyze the teaching model in the past fifteen years, and predict that the blended teaching model will become a popular teaching model according to the hot spot analysis map and keyword clustering map. Then, we carry on the teaching design to the course of the "Web design and production", and apply it in the secondary vocational schools. Practice has proved that the blended teaching model can significantly improve students' academic performance.
