基于外来反馈理论的二胡教学探究

Research on Erhu teaching from the perspective of external feedback theory

反馈是控制论的基本规律,其相关原理运用于二胡教学中可实现科学的教学控制,使学生更加快速地掌握演奏技术.二胡教学中可以灵活运用不同形式的外来反馈,从心理层面尊重学生的注意力规律,关注学生的情绪激活,激发学生的想象力;从生理层面加强训练引导,唤醒学生的感官刺激状态,促进学生的生理放松,强化学生的听觉反馈,从而提升二胡的教学效果.

Feedback is the basic rule of cybernetics.The relevant principles can be applied to Erhu teaching,which can realize scientific teaching control and make students master the playing technology more quickly.In Erhu teaching,we can flexibly use different forms of external feedback,respect the attention rules of students from the psychological level,pay attention to the emotional activation of students and stimulate the imagination of students;strengthen training guidance from the physiological level,awaken the sensory stimulation state of students,promote the students’physiological relaxation,strengthen the students’auditory feedback,and improve the teaching effect of Erhu.
