摘　　要：为使物理实验教学适应新时代人才培养目标,以衍射光栅实验为例,适当调整教学环节,使教学活动形成“光栅原理→光栅衍射实验→光谱仪→光谱仪的应用”模块化闭环体系,强化学生的系统性思维、从原理到仪器的思维等,实现从知识到能力的进阶,提升人才培养质量.光谱仪的应用教学内容为测量手机显示屏白屏光谱,增强实验的趣味性和多样性,充分调动学生积极性,对手机光谱进行高斯分解,解析其色域和显示原理,专业技术教育悄然融入.解析不同时期的手机显示屏,还能展现显示技术的进步和发展.Surrounding the teaching idea of modular and circular knowledge system from principle,grating diffraction experiment to spectrometer and its application,the teaching activity of diffraction grating experiment is adapted for new engineering talents,such as systematic thinking,thinking from principle to instrument.Thus,the progress from knowledge to ability is fulfilled and talent training quality can be improved.For the teaching procedure of spectrometer and its application,the spectra of phone displays were recorded by grating spectrometer and decomposed by Gaussian fitting,to elaborate color gamut and display principle of phone displays.Interesting,utility and profession are integrated in this experiment.The color gamut expansion of phone screens reflects the progress of display technology over time.
