Clinical nutrition is an important course in nursing. Based on the prominent problems in the courses of clinical nutrition in China, such as the suboptimal professional capability of teaching forces, outdated teaching modes, and insufficient depth of ideological and political education, this study proposed the curriculum construction goal as “One Body, Two Wings”, which takes teaching reform as the main body, ideological and political education, and professional competency training as the two wings. The teaching reform adopted the “student-centered” teaching model by optimizing teaching modules, increasing the weight of practice, strengthening process assessment, etc. Through these effective approaches, the teaching reform improved teaching quality and strengthened students’ abilities in knowledge application. This study suggested that more efforts should be taken to support the training of professional teachers, carry out effective teacher-student communication, and promote novel and diversified student-centered teaching forms. By these comprehensive measures, we aimed to train high-quality nutritional professionals with distinct ideological and political consciousness as well as excellent professional competency and contribute to the Healthy China Goal.展开更多
