Under the background of vocational education reform, English teaching, as a key link in the articulation of high school through courses, has a direct impact on the quality of teaching and the coherence of talent cultivation. For this reason, based on the establishment of the “three-module nine-type” higher vocational English culture curriculum system, the article introduces the SPOC teaching platform to design a higher vocational English flipped classroom teaching model. Students of a vocational school in S city were selected as the research objects, and teaching experiments under different teaching modes were designed to investigate the changes of students’ English performance and learning ability. The experiment shows that there is a significant difference between the English achievement of the post-test experimental group and the control group (t=6.395, Sig=0.000<0.01), and the average relative vocabulary acquisition rate of the experimental group is 74.56%, which is different from that of the control group (t=9.512, P=0.000<0.01). And the students’ international communication ability increased from 2.015 to 4.634, and its increase reached 129.98%. Therefore, optimizing the construction path of senior English cultural curriculum system and promoting the reform of English teaching mode is an important way to improve students’ English expression and lay a solid foundation for promoting students’ international communication ability.
