特别是在农村中小学,存在后进生的现象特别严重。后进生对学习产生逆反心理的情绪,是制约教学质量提高的一大瓶颈。后进生的成因是多方面的,有家庭的、有社会的;有智力方面的,也有非智力方面的;有先天的、也有后天的。在教学中可以通过激发后进生对数学学习的兴趣,培养他们自觉学习的良好习惯,传授正确的学习方法,提高他们解题能力等有效途径来转化后进生。 Especially in rural primary and secondary schools, the phenomenon of post-graduation existence is particularly serious. Late-born students have the opposite psychological emotion, is to restrict the quality of teaching a big bottleneck. The cause of post-graduation is multi-faceted, family, social; intellectual, there are non-intellectual aspects; there are innate and acquired. In teaching can be inspired by post-graduate interest in mathematics learning, training their good habits of conscious learning, imparting the right learning methods to improve their ability to solve problems and other effective ways to transform students.
