基于职业能力的医学影像物理逆向教学探析

Research on Medical Imaging Physics Reverse Teaching Based on Professional Ability

立足于医学影像物理课程的交叉性、综合性学科特点;以杜威的教学论观点为指导:知识的有效获取源于活动的具体情境;融合了学生的未来影像职业能力要求:对影像机制的逻辑认知,对影像内容的研究判读,对成像模态的融合探究等,分析得出影物课程逆向教学的根本意义:唤起学生的职业认同感、归属感。最后探析了影物课程逆向法教学实施思路,以促进学生的自主学习能力为制高点,在充分考虑学情的基础上,科学整合课程内容,合理拟定评价指标,促进"教"与"学"的良性互动。

This article is based on the interdisciplinary and comprehensive characteristics of the medical imaging physics course;guided by Dewey＇s theory of teaching：the effective acquisition of knowledge is derived from the specific situation of the activity;it integrates the students＇ requirements for the future image professional ability：the logical cognition of the image mechanism and the study of the content of the image.Analysis of the integration of imaging modalities,and so on,it is concluded that the basic significance of reverse teaching of shadow courses is to arouse students＇ professional identity and sense of belonging.In the end,the idea of implementing the teaching of reverse course in the course of shadow objects is discussed,in order to promote the students＇ self-learning ability to be a high point.On the basis of taking full consideration of the learning situation,the content of the curriculum is integrated scientifically,the evaluation indexes are rationally drawn up,and the positive interaction between teaching and learning is promoted.
