基于OBE理念的“医用数学建模”教学设计与实践

Teaching design and practice of"medical mathematical modeling"based on OBE concept

目的基于成果导向教育(outcomes-based education,OBE)理念,以提升学员医用数学建模能力为目标,围绕《医用高等数学》课程中医用数学建模模块进行教学设计与实践并明确改进方向。方法以“传染病模型”为例,进行教学实践;随后利用问卷方式收集44位学员反馈意见。综合运用统计描述、Mann-Whitney U检验、单因素方差分析和Scheffe法,以及卡方检验和z-检验对数据进行分析。结果90.91%的学员对课程主题感兴趣,65.91%的学员认为该模式明显提升了学习效果。本次课程中学员学习主动性在对课程主题有、无兴趣这两个水平上无显著差异,而对知识点掌握程度和继续开展翻转课堂的意愿却有显著影响。结论教学模式总体有效,但需在“突出建模,淡化计算”、提升学员参与度和强化课堂学习效果3个方面进一步改进。

Objective Based on the concept of outcomes-based education(OBE),aiming to improve students'medical mathematical modeling ability,the teaching design and practice of mathematical modeling module for the course Medical Advanced Mathematics are carried out and the direction of improvement is defined.Methods Taking infectious disease model as an example,teaching practice was carried out,and then questionnaires from 44 students were collected for feedback opinions.Statistical description,Mann-Whitney U test,one-way ANOVA and Scheffe method,as well as chi-square test and z-test were used to analyze data.Results The results showed that 90.91%of the students were interested in the subject of the course,and 65.91%of the students thought that this mode significantly improved the learning effect.In this course,there was no significant difference in the learning initiative of students on the two levels of being or not being interested in the course topic,but it had a significant impact on their mastery of knowledge points and their willingness to continue to carry out flipped classroom.Conclusion The teaching mode is generally effective,but it needs to be further improved in three aspects:emphasizing modeling and downplaying computation,enhancing students'participation and strengthening the classroom learning effect.
