Abstract: In order to serve the construction goal of the university's first-class undergraduate major and applied talents training plan, this paper takes the core course seepage mechanics of petroleum engineering major as an example. By analyzing the current teaching status and existing problems, the platform of Superstar Learning was used to pull together online course resources, and the teaching modes were integrated into offline traditional classes, such as case type, group discussion type and special report type. These measures could give full play to the advantages of online and offline mixed teaching to improve students'course participation and learning efficiency. And through optimizing the curriculum assessment, a non-standardized evaluation system was established, which might promote the transformation of high-quality discipline resources and scientific research resources into curriculum education resources, resulting in cultivating students'engineering application ability and innovation ability.

Key words: Seepage mechanics, Online and offline, Mixed teaching, Applied talents, Non-standardized evaluation, Teaching reform
