陶行知先生曾说过:“先生的责任不在教,而在于教学生学。”使学生从学会到会学,以研究学生为基石,以学定教、以教导学,让学生在参与数学活动中,积累不同的活动经验,培养数学思考、发展分析数据观念。联系生活,正是学生进行数学活动、迁移已有经验的触发器。知识的学习又是为了运用与实践,让学生在利用平均数的知识解释生活现象的过程中感受平均数的无穷变化。
Mr. Tao Xingzhi once said: “The responsibility of the teacher is not teaching, but rather teaching students. ” To enable students to learn from learning, to study students as the cornerstone, to learn to teach, to teach learning, so that students Participate in mathematical activities, accumulate experience of different activities, develop mathematical thinking, the development of analytical data concepts. Contact life, it is students conduct mathematical activities, the migration of the trigger has been experienced. Knowledge is to learn and practice, so that students in the use of average knowledge of life phenomena in the process of feeling the endless changes in the average.
