在实施素质教育的今天,我们都深感“满堂灌”、“填鸭式”、“题海战”等陈旧的教学方法已非弃不可。然而,实际的教学活动中,我们不少教师对上述方法依然恋恋不舍,似有“谈之应弃、弃之可惜”之感。其实,对于知识的掌握如何才能更为深刻,关键之处在于教育者如何使受教育者所学知识在大脑中留下历时更长、形象更鲜明的烙印。皮亚杰曾说过:一切经验、知识发展源于实际动作。苏霍姆林斯基亦曾说过:手和脑之间有着千丝万缕的联系,手使脑得到发展,使它更加机智:脑使手得到发展,使它变成思维的工具和镜子。由此可见,要使学生对知识掌握得更为牢固,在课堂教学中就应精心设计部分操作活动,把学生都推到主体的位置上,让学生 In today’s implementation of quality education, we all deeply feel that we can not afford to abandon the old teaching methods such as “full house irrigation”, “spoon-feeding” and “marine warfare”. However, in the actual teaching activities, many of our teachers are still reluctant to give up the above method. It seems that there is a sense of “discarding discards and giving up pity”. In fact, how to master the knowledge can be more profound, the key lies in how educators educate those who have learned to leave a longer, vivid image of the brains. Piaget once said: All experience, knowledge development stems from the actual action. Sukhomlinski also said that there is a myriad of connections between the hand and the brain, and that the hand develops the brain and makes it more witty: the brain develops and makes it a tool and a mirror for thinking . Thus, to enable students to master the knowledge more firmly in the classroom teaching should be carefully designed part of the operating activities, the students are pushed to the main position, so that students
