差生制约着教学质量的全面提高。木桶理论认为:决定木桶容量的多少,不是取决于最长的那块木板,而是取决于最短的。因此,差生的转化是摆在每个教师面前迫在眉睫的问题。尽管教育者竭尽心智,对造成差生的原因、转化措施各抒己见,取得了一定的效果,但差生问题错综复杂,甚至连理论界都各执 Poor students restrict the overall improvement of teaching quality. Barrel theory believes that determining the capacity of a barrel does not depend on the longest piece of wood, but on the shortest. Therefore, the transformation of poor students is an imminent problem placed before every teacher. Although the educators have exhausted their minds and expressed their opinions on the causes of poor students and conversion measures, they have achieved certain results, but the problems of poor students are complicated, and even the theoretical community has held different opinions.
