According to the problems existing in the experimental teaching system of scanning electron microscope

such as the implementations of experiments are mainly by theory explaining and operation of the teachers

without students’ initiative participate

the teaching effect is very poor. Teaching reform methods of improving experimental teaching effect were established. Experiment teaching contents and improved methods were carefully designed. Case teaching method was used to deepen students’ understanding of secondary electrons and backscattered electron images

resolution ratio and depth of field. Observation of self-made samples was added. Energy disperse spectroscopy applications were emphasized. Experiments are more interesting and the students’ desire for knowledge is stimulated by the way of theoretical explanation and related graphic calculations. The leading role of students in the experimental process is demonstrated

the students’ abilities are raised

and the teaching effects are improved.
