STEAM教育理念下“线上+线下”混合教学模式初探:以微生物学实验为例

The“online+offline”blended teaching mode under the concept of STEAM education:taking Microbiology Experiment as an example

随着信息化手段的不断丰富,新型教育理念结合线上学习平台的新信息化教学模式成为高校课堂的改革新趋势。本次教学改革利用科学(Science)、技术(Technology)、工程(Engineering)、艺术(Art)和数学(Mathematics)多学科融合的超学科教育理念(简称STEAM教育)对教师教学过程进行了整体设计,同时借助“线上+线下”教学平台对学生学习过程进行了全面优化。将原本分散的验证型、操作型实验重新整合串联成以多角度“项目式”任务为主线、以Blackboard线上平台为辅线的自主研究型实验项目。新型教学模式以学生为主体,给学生提供更多自我展示和讨论互动的平台。从学生的课堂表现、知识测验、课后反馈、实验操作及实验报告4个方面对新型模式下的教学效果进行了分析和评价。结果表明,此模式不仅提高了学生在微生物学实验中的学习质量,增强了其学习主观能动性,而且有利于培养和提升学生的问题探究及实践创新能力。这一新型教学模式对其他生物学科实验课程的教学具有一定的借鉴意义。

With the continuous enrichment of information technology,the e-education guided by new education concept and combined with online learning platform has become a novel trend of teaching reform in colleges and universities.We introduced science,technology,engineering,art and mathematics(abbreviated to STEAM)education concept to design the overall teaching process and comprehensively optimized the students’learning process by introducing the“online+offline”teaching platform.The original scattered verification and operation experiments were re-integrated into an independent research-based experiment project with multiple tasks as the main line and Blackboard online platform as the auxiliary line.In the novel teaching mode,we taught in a student-centered manner and provided students with more platforms for self-presentation and discussion.Then,we analyzed and evaluated the teaching quality from four aspects:students’performance,knowledge test,after-class feedback,and experimental operation and report.The results indicated that this teaching mode not only improved students’learning quality and subjective initiative in Microbiology Experiments but also cultivated students’ability of problem solving and innovation in practice.This new teaching mode has reference significance for the teaching of experiment courses in other biological disciplines.
