疫情防控期间专业课新型“线上-线下”混合教学模式探索

在全球新冠疫情影响下,2020年春季学期我国高校普遍无限期延迟开学,面对“停课不停教、停课不停学”的要求,适合高校专业课教学的“线上-线下”混合教学模式面临“线上”资源严重不足与无法开展“线下”教学的挑战,迫切需要在实践中探索出适合疫情防控期间的新型“线上-线下”混合教学模式。文章以《热处理原理》专业课为例,探索了大学MOOC课前在线学习+课上腾讯会议直播+实验在线模拟演练+课间与课后微信群/QQ群交流互动4个环节的新型“线上-线下”混合教学模式,强化了学生对专业知识的理解,可以有效提高教学效果与学生对新知识点的理解程度以及具体实验过程的感性认知,是疫情防控期间专业课新型“线上-线下”混合教学模式有效探索,将有助于针对特殊时期与特殊学生开展有效教学模式探索,为我国“双一流”建设贡献智慧与力量。
