在数学教学中通过说、画、比等方法,使学生学会从数学角度发现问题、解决问题、分析问题和综合运用数学知识解决简单的实际问题,获得解决问题的一些基本策略(方法),有助于学生体会解决问题方法的多样性,有利于发展学生的应用意识、创新意识和实践能力,有益于学生学会与同伴交流,养成评价和反思的意识。一、在观察和交流中培养学生解决问题的能力观察是解决问题的前提,解决问题离不开观察,学生常通过观察来收集新资料,发现新事实,认识问题的本质,揭示数量关系,探求解题方法。在观察的基础上,通过交流帮助学生把事物的、图画的、符号的、口头的数学信息联系起来,既
In mathematics teaching, we can make students learn how to find problems, solve problems, analyze problems and comprehensively use mathematical knowledge to solve simple practical problems and get some basic strategies (methods) to solve the problems through methods such as speaking, drawing and comparing. To help students understand the diversity of methods to solve problems, is conducive to the development of students’ awareness of application, innovation and practical ability, which is conducive to students learn to communicate with peers, develop awareness of evaluation and reflection. First, in observation and exchange of students’ ability to solve the problem of observation is the premise to solve the problem, to solve the problem can not be separated from observation, students often through observation to collect new information, discover new facts, recognize the nature of the problem, reveal the relationship between quantity and explore Problem solving method. On the basis of observation, we help students to connect the mathematical, pictorial, symbolic and verbal mathematical information through communication
