基于问题导向的农业物料工程特性实验课教学探索

Exploration on Problem Oriented Teaching of Experiment Course of Agricultural Materials Engineering Characteristics

农业物料工程实验课程教学在农林类院校培养研究生科研、创新意识,以及提供农业物料基本工程数据等方面发挥着关键作用,传统实验教学大多为机械式照搬实验指导,重现数据,忽略了研究生的理论基础和主观能动性。该文提出在农业物料工程特性实验课程中以学生科研课题需求为导向,设置扫描电镜、原子力显微镜和红外光谱等实验内容,以农业物料的理化特性表征分析贯穿始终,最后通过撰写论文报告采用团队互评等形式可显著提升课程实效。

Teaching of experimental course on agricultural materials engineering characteristics plays a key role in cultivating postgraduate students’consciousness of scientific research and innovation,and providing data of agricultural materials basic engineering,etc.in agriculture and forestry colleges.Most of traditional teaching experiments only copies experimental instruction and reproduced data repeatedly,while ignores theoretical basis and subjective initiative ability of postgraduate students.It was proposed that experimental course of agricultural materials engineering characteristics was guided by needs of students’scientific research topics,and included scanning electron microscope,atomic force microscope,infrared spectroscopy and so on.Physical and chemical characteristics of agricultural materials were characterized and analyzed throughout.Finally,effectiveness of the course could be significantly improved through writing thesis report and evaluating mutually in team.
