慕课背景下材料科学与工程专业大型仪器实验教学模式探究——以透射电子显微镜为例

Exploring the Teaching Mode of Large Instrument Experiments in Materials Science and Engineering under the Background of MOOC—Take Transmission Electron Microscopy as an Example

大型仪器在材料科学与工程专业中具有重要的地位,正确合理地使用大型仪器可以促进科学研究的快速发展。由于大型仪器比较昂贵,传统线下实验课教学以课堂讲解和演示为主,导致学生的学习效果不理想。因此,为了更好地开展实验课教学,近年来各大高校逐渐将慕课教学引入实验课教学中。本文以透射电子显微镜为例,提出开展大型仪器线上线下混合式教学模式,学生先利用慕课资源进行理论学习和模拟操作,随后再开展线下实验操作,以培养出同时具有扎实理论知识和良好操作技能的学生。

Large instruments play an important role in the field of materials science and engineering,and the correct and reasonable use of large instruments can promote the rapid development of scientific research.Due to the high cost of large instruments,traditional offline experimental teaching mainly focuses on classroom explanations and demonstrations,resulting in unsatisfactory learning outcomes for students.Therefore,in order to better carry out experimental teaching,major universities have gradually introduced MOOC teaching into experimental teaching in recent years.Taking the Transmission electron microscopy as an example,this paper proposes to carry out online and offline hybrid teaching mode for large-scale instruments.Students first use MOOC resources for theoretical learning and simulation operation,and then carry out offline experimental operation,so as to cultivate students with solid theoretical knowledge and good operating skills.
