新课程实验教材中选编了丰富多彩的情境图,目的是激发学生的学习兴趣,让他们积极参与探求知识的过程,感受数学与生活的密切联系,体会到数学的应用价值,并能积极主动地运用数学知识去解决生活中的实际问题。然而,现实中因教师理解和把握上的偏差,导致不能有效地实现情境图的功能价值,使得教学低效。因此,我们要认真探究教材中的情境图,透过多彩的场景,挖掘它蕴含的实质,让情境图焕发出新的光彩。一、把握情境图蕴意,引导学生达到目标深入钻研情境图的蕴意,是用好情境图、确定教学目标、有效实施课堂教学的前提。只有在理解情境图含意的基础上创设情境,才能有效落实教学目标,这样的课堂教
The new curriculum experimental materials selected a rich and colorful scenarios, the purpose is to stimulate students interest in learning, so that they actively participate in the process of exploring knowledge, feel the close connection between mathematics and life, to appreciate the value of mathematical applications, and can be proactive Use mathematical knowledge to solve practical problems in life. However, in reality, due to the deviation of teachers’ understanding and grasping, the function value of situation diagram can not be effectively realized, making the teaching inefficient. Therefore, we must carefully explore the contextual maps in the textbooks and explore the essence of the scenario through colorful scenes so as to give the situation diagrams a fresh glorious future. First, grasp the meaning of context map, guide students to achieve the goal Depth study of the meaning of context map is to use the situation map, determine the teaching objectives, the effective implementation of classroom teaching premise. Only in understanding the meaning of context map based on the creation of context, in order to effectively implement the teaching objectives, such a classroom
