数学课程改革的重要理念之一,是数学教学应从生活实际出发,加强实践活动,培养学生的应用意识及运用数学解决实际问题的能力,从而实现“人人学有价值的数学”、“人人都能获得必需的数学”。这正体现出实践活动在数学学习活动中的重要位置。一、体验——培养儿童的参与意识和应用意识数学是从现实世界中抽象出来的。在教学时,依据教学内容的需要,开展一些体验性的实践活动,让学生接触现实社会,联系日常熟悉的量与物、人和事、学习与生活实际,体会数学与自然及人类生活的密切联系,了解数学的价值,意识到生活中处处有数学,增进对数学的理解和应用数学的信心。
One of the important concepts of mathematics curriculum reform is that mathematics teaching should proceed from the reality of life, strengthen practical activities, cultivate students’ sense of application and use mathematics to solve practical problems so as to realize “valuable mathematics for all”, “ Can get the necessary mathematics. ” This is an indication of the importance of practical activities in math learning activities. First, the experience - to develop children’s sense of participation and awareness of the application of mathematics is abstract from the real world. In teaching, based on the needs of teaching content, to carry out some experiential practical activities to enable students to contact with the real world, contact daily familiar with the amount and things, people and things, learning and living reality, experience mathematics and nature and human life are closely Contact, understand the value of mathematics, aware of the math everywhere in life, to improve the understanding of mathematics and the confidence of applying mathematics.
