教育家陶行知先生说:“学生有了兴味,就肯用全副精神去做事,学与乐不可分。”数学教学也是这样,教师要着力培养学生的学习兴趣,以最大限度地提高课堂教学效率。开课激趣,引发学生的学习欲望。比如在学习“集合”这一概念时,我出示了一幅生动有趣的挂图,图上画着一个池塘,池塘的边上长着一棵茂盛的大柳树,树下是一群小鸡在草地上觅食,池塘里一群小鸭子在水中嬉戏,大柳树上面的天空一群小燕子在飞舞。我指着画面问学生:“这些小动物们在春天的池塘 Tao Xingzhi, an educator, said: ”When students are excited, they are willing to use their energies to do their work and learn with them.“ Mathematics teaching is also the case. Teachers should focus their efforts on cultivating students’ interest in learning so as to maximize classrooms Teaching efficiency. Start-up interest, triggering the desire of students learning. For example, in learning the concept of ”collection“, I presented a lively and interesting wall chart with a pond on the map, a flourishing willow tree on the edge of the pond and a group of chickens under the tree Feeding on the grass, a group of ducklings in the pond playing in the water, a group of little swallows flying in the sky above the willows.
