在日常生活及实际计算中,估算都有着非常重要的作用,脑科学家们普遍认为估算训练可以帮助人们开发大脑的数学机能。然而,在具体的教学活动中,部分教师对估算教学给予的重视程度不够,这就造成了学生对估算价值的理解不够深入,强化学习的意识薄弱,估算方法掌握得过于单一等问题。从目前尚存的这些问题入手,结合实例具体分析了如何有效发展小学数学估算教学的几点措施。 Estimation plays a very important role in daily life and actual calculation. Brain scientists generally think that estimation training can help people develop the mathematical function of the brain. However, in the specific teaching activities, some teachers do not pay enough attention to the evaluation teaching, which leads to the students’ insufficient understanding of the evaluation value, the weak awareness of reinforcement learning and the over-estimation of estimation methods. Starting from these extant problems, this paper analyzes concretely how to effectively develop mathematics estimation teaching in primary schools.
