Abstract: As a core course in the Surveying Engineering major,the teaching quality of fundamentals of geodesy directly impacts the quality of talent cultivation in this field.Based on the OBE (outcome-based education)approach,which advocates “output-oriented”,“student-centered” and “continuous improvement” teaching philosophies,and utilizing modern information technology in teaching methods,this study explores the teaching process to enhance the quality of core courses in Surveying Engineering.This research is of significant practical relevance.The paper discusses the design and implementation of a blended teaching approach across three stages: pre-class,in-class,and post-class,both online and offline.It also integrates ideological and political elements with specific teaching cases to enrich classroom content and improve teaching quality.The beneficial conclusions drawn from the implementation of blended teaching provide valuable references for teaching other courses.

Key words: OBE, blended teaching, ideological and political elements, implementation effects
