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

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.
