大多数的孩子是喜欢画画的,心理学家克鲁切茨在对儿童的研究中就发现:许多天才儿童是借助画图来解决问题的。让学生在“画”数学的过程中理解题意,理清数量关系,搜寻到解决问题的突破口,形成解题策略,这样枯燥乏味的数学就变得具体化、直观化,简便易懂,有助于数学思想的发展。一、画出解题策略在解决问题的教学中,特别是碰到一些稍难的习题,有时单靠分析,学生也不一定能够理解,而教师讲解起来费力且费时,这时我们可以借助图形来帮助学生理解题意。教学中可让学生在本子上涂涂、画画,借助实物草图或线段图等把抽象的
Most children like to draw, psychologist Krutzec found in the study of children: many talented children solve problems by drawing. Let the students understand the questions, clarify the relations of quantity, find the breakthrough point of solving the problems and form a solution strategy so that the dull mathematics becomes concrete, intuitive and easy to understand , Contribute to the development of mathematical thought. First, to draw a solution to problems in teaching strategies, in particular, encountered some difficult exercises, and sometimes rely on analysis, students may not be able to understand, and teachers explain it laborious and time-consuming, then we can use graphics To help students understand the problem. Teaching students can paint on the book, drawing, with the help of physical sketch or line drawing abstract
