目的探讨X线机限时电路教学方法,以提高教学质量。方法将06级中专影像技术班54人为对照组,07级中专影像技术班46人为实验组。对照组采取理论课以讲授为主,先理论后实践的教学方法,实验组采取PDCA循环教学。对两组学生限时电路的分析和限时器故障检修成绩进行统计分析。结果实验组考核成绩及对教学满意度均优于对照组(P<0.01)。结论 PDCA循环可提高X线机限时电路教学效果及学生的学习兴趣。
Objective To explore the teaching methods of X-ray machine limit circuit to improve teaching quality. Methods Sixty-four technical secondary school students were selected as control group and 46 secondary technical secondary school students as experimental group. The control group to take the theory of teaching-based, first theory after the practice of teaching methods, the experimental group to take PDCA cycle teaching. The two groups of students limit circuit analysis and time-limiter troubleshooting results for statistical analysis. Results The results of the experimental group and teaching satisfaction were better than the control group (P <0.01). Conclusions The PDCA cycle can improve the teaching effect of X-ray machines and the learning interest of students.
