儿童思维发展的一般规律是从具体操作开始的,再逐步形成抽象的思维。教学设计时,充分考虑儿童的原有认知水平及儿童心理发展水平,放手让学生自主探究,注重让学生在观察、操作、合作交流、比较等数学活动中,找出计算组合图形面积的多种方法,并进行优化选择。学生在解决问题的过程中,获得数学学习方法。在对学习过程与结果的反思中,提高解决问题的能力。现将教学中遇到的问题以及解决方法与同行们交流。
The general law of children’s thinking is to start from the specific operation, and then gradually form an abstract thinking. Teaching design, give full consideration to children’s original cognitive level and children’s psychological development level, let the students explore, pay attention to let students in observation, operation, cooperation and exchange, comparison and other mathematical activities, find the combination of graphics area and more Methods, and optimize the choice. Students in the process of solving problems, access to math learning methods. In the process of reflection on the learning process and results, improve the ability to solve problems. Now the problems encountered in teaching and solutions to communicate with colleagues.
