Abstract: In response to the issues of fragmented knowledge,inadequate logical reasoning,and lack of practical application in online teaching of natural medicinal chemistry,the teaching team proposes an online teaching model called "One Body,Three Wings" with the main theme of "expected learning outcomes,adjustment of teaching content and teaching system,and assessment of learning outcomes" based on the OBE (Outcome-Based Education) teaching concept.This model takes "professional talent cultivation" as the main focus and consists of three wings:"adjustment of teaching content," "reform of teaching methods," and "optimization of assessment methods." This model helps students achieve teaching goals that emphasize mastering basic theoretical knowledge as a foundation,developing proficient application skills,and enhancing critical and innovative thinking by comprehensively applying knowledge and abilities.
