Building first-class undergraduate curriculums that meet the requirements of China’s new era and forming world-class undergraduate curriculum systems with Chinese characteristics are important parts of deepening education reform and revitalizing undergraduate education. This research focuses on the reform of first-class undergraduate courses and proposes an integrated teaching mode that combines theory, cases, simulation and practice. Taking the undergraduate course of engineering valuation as an example, based on the OBE education concept, it centers on the construction and practical application of the integrated teaching mode. While deepening the education reform and promoting the transformation of teaching mode, it integrates teaching with practice, and explores a teaching mode and implementation path that meet the requirements of the curriculum system and cultivation objectives of engineering valuation, as well as the future development needs of the industry. By analyzing typical achievements of actual construction projects, this research aims to provide reference for the reform of first-class courses construction of engineering valuation.
