在小学数学教学中,运用恰当的课堂设疑,既能起到反馈课堂教学信息的作用,又能揭示教材的内在联系,促进知识的迁移,还能激发学生的学习兴趣,活跃课堂气氛,集中学生注意力,起到良好的教学效果。在数学教学中,某些知识内容比较抽象,学生理解起来比较困难。在教学中,可以运用一些通俗易懂的语言,把一些枯燥的知识通过打比喻,让学生在欢笑中领悟其所包含的内涵,让学生在回味中感染、陶醉。从而集中学生的注意力,调动学生的兴趣,加深对知 In the elementary mathematics teaching, using the appropriate class to set up doubts not only plays the role of feedbacking the classroom teaching information, but also reveals the internal connection of the teaching materials, promotes the transfer of knowledge, stimulates students’ interest in learning, activates the classroom atmosphere and concentrates Students attention, play a good teaching effect. In mathematics teaching, some of the contents of knowledge is more abstract, students understand more difficult. In teaching, you can use some easy-to-understand language, some boring knowledge through analogy, so that students understand the content contained in the laughter, so that students feel aftertaste, intoxicated. Thus concentrating students ’attention, mobilizing students’ interests and deepening their knowledge
