Abstract: Objective: To explore the application of the O-AMAS effective teaching model in the "Health Assessment" course and
evaluate the effectiveness. Methods: Nursing students in grades 2020 and 2021 of Dali University were selected as the study objects
and divided into the control group and the experimental group according to teaching mode. The traditional teaching mode was adopted
in the control group, while the O-AMAS effective teaching model was used in the course teaching design for the experimental group.
The results of critical thinking ability, autonomous learning ability, in-class test and teacher-student mutual evaluation were compared
between the two groups. Results: The scores of critical thinking ability, autonomous learning ability, student evaluation, teacher
evaluation and in-class test of the experimental group were significantly higher than those of the control group （P < 0.001）.
Conclusion: Integrating the O-AMAS model into the course design of "Health Assessment" can improve the teaching quality and
teacher-student satisfaction, and cultivate students' autonomous learning ability and critical thinking ability. The O-AMAS teaching
model can be applied to other courses as well.
