摘要
针对目前高校扫描电子显微镜实验开设现状不足之处,提出了将多媒体技术融入到实验教学当中的想法。以雨课堂为教学平台,制作了电镜教学多媒体课件,实现可动态化观察仪器内部构造,有助于学生更好地理解相关理论知识。并设计了观察样品表面形貌和元素分析实验,使学生从实践当中更好理解仪器工作原理和操作仪器。经过两年教学实践,效果良好。
Aiming at the insufficiency of the present situation of scanning electron microscope experiment in present colleges,we put forward a design of integrating multimedia technology into experimental teaching.Using Rain Classroom as a teaching platform,making multimedia courseware of the electron microscope teaching,realizing the dynamic observation of the internal structure of the instrument,can help students understand the relevant theory knowledge better.We have designed sample surface morphology observation and elemental analysis experiments,so that students can better understand and operate this instrument from practice.After two years teaching practice,the effect is good.
