每逢周日,女儿总会坐到古筝前练习几首小曲。随着四指的拨动,指甲碰触着琴弦,悠美的旋律从指尖流淌而出。此时,女儿正在弹奏《渔舟唱晚》,那时而急、时而缓,时而轻、时而重,仿佛天籁般的声音引得我不禁驻足倾听。看着女儿那自我陶醉的模样,作为老师的我忽然有一种想法,要是我们也能将一节节数学课演绎得像一首首曲子那样优美动听,学生岂有不投入之理? Every Sunday, my daughter always practices a few songs in front of the guzheng. With the four finger toggle, nails touch the strings, beautiful melody flowing from the fingertips. At this point, my daughter is playing “fishing boat singing late”, then urgent, sometimes slow, sometimes light, heavy, as if the sounds of nature attracted me to stop listening. Looking at her daughter that self intoxicated appearance, as a teacher, I suddenly have an idea, if we can also be a section of mathematics lesson deduced as a first song as beautiful and pleasant, students have not put reason?
