| 婴幼儿营养状况评价是营养与食品卫生学实验教学中的一项基本技能。设计开发本虚拟仿真实验可解决实验实操过程中婴幼儿活泼好动、配合度差等问题，并基于此虚拟仿真项目应用将预防医学的实验教学方法进行探索。本实验采用线上线下混合式教学，丰富了教学手段，强化了婴幼儿营养状况评价规范流程，经过2018年春至2020年春3个学期的实践运行，达到优秀成绩的学生比例分别为30.09%（34/113）、56.02%（279/498）和66.79%（1 080/1 617），逐年升高（P趋势<0.001）。通过对参与实验操作的2 228名学生进行课后的满意度调查显示，1 983名（89.00%）学生认为本实验教学可以更好地培养自主学习能力。学生通过虚拟仿真实验的学习，提升了学生的主观能动性，为实现学生全面素质的提高和学校精英教育的要求奠定了基础。 |

| Infant nutritional status evaluation is a basic experimental skill in the experimental teaching of nutrition and food hygiene. The construction of this virtual simulation experiment can solve the problems of activeness and poor coordination of infants and young children in the actual operation of the experiment. And based on the application of this virtual simulation project, the experimental teaching method of preventive medicine was explored. This experiment adopted online and offline mixed teaching method, which enriches teaching measures and strengthens the standardized process of infant nutritional status evaluation. After 3 semesters of practice from spring 2018 to spring 2020, the proportion of students who achieved excellent grades was 30.09% (34/113), 56.02% (279/498) and 66.79% (1 080/1 617), respectively, which increased significantly year by year (Ptrend < 0.001). Among all the 2 228 students, 1 983 students (89%) believed that this experimental teaching could better cultivate the ability of autonomous learning. Through the study of virtual simulation experiments, students have improved their subjective initiative, and laid a foundation for the improvement of students' overall quality and the requirements of school elite education. |
