双向互动型教学模式在核磁共振课程中的实践与探讨

目的：针对目前核磁共振课程教学过程中存在的问题，基于核磁共振理论体系与成像实践的特点，打破传统的以教师为中心的教学方法，构建以教师为主导、以学生为主体、以理论教学为基础、以实验教学为主线、双向互动为原则的教学模式。方法：从教学内容设置、启发式教学、综合设计型实验、远程实验平台等方面进行双向互动型教学模式的实践与探讨，创建新的核磁共振课程教学体系。结果：教学新体系以引导学生主动性学习为主，重视学生个性发展和创造力的培养。形成一套课内与课外、理论与实践，集课堂教学、实验和计算机辅助教学的多方位立体式教学构架。结论：该教学模式的建立有利于推动核磁共振课程教学方式的改革，能够充分调动学生的学习兴趣和积极性，强调以培养学生综合实践能力为目标，有效提高学生分析解决问题的能力，进一步拓展学生的创新思维，为医学影像专业培养更多磁共振应用型技术人才。

Exploration and Practice of the Two-way Interactive Teaching Mode in the NMR course

Objective： For the current problems existing in the teaching process of nuclear magnetic resonance （NMR） course and on the base of the characteristics of the practice of nuclear magnetic resonance （NMR） theoretical system and imaging practices, we break the traditional teacher-centered teaching method and construct the teaching mode which is teacher-led, student-centered, based on theoretical teaching, making experimental teaching as the main line and using two-way interactive principle. Methods： We discuss and practice two-way interactive teaching mode, which composes of the contents of teaching, the heuristic education, comprehensive design experiments, and remote experiment platform. In this way, we create a new nuclear magnetic resonance （NMR） courses teaching system. Results： New teaching system can give priority to guide students＇ initiative in learning. And it pays attention to cultivate the students＇ individuality development and creativity. At last, it forms a set of multi-faceted three-dimensional teaching architecture--utilizing curricular, extracurricular, theory and practice--which is combined with classroom teaching, experiment and computer-aided teaching. Conclusions： The establishment of the teaching mode is beneficial to the reform of NMR teaching mode. It can fully mobilize students＇ learning interest and enthusiasm. It emphasizes to make cultivating students＇ comprehensive and practical ability as the goal. In addition, it also improves the students＇ ability of analyzing and solving problems and further develops the students＇ innovative thinking ability. This teaching mode will help to train more applied magnetic resonance and technological talents for Medical Imaging Specialty.
