小学数学知识比起小学阶段的其他学科抽象难懂,再加之小学生自身的理解能力差,导致很多学生在学习数学时效率较低,兴趣不浓。为此,创设情境教学,将抽象的数学知识具体化、形象化,使学生产生如临其境之感,对知识从形象的感知向抽象的理性阶段过渡很有必要。情境教学模式的建立有利于激发学习兴趣,促进学生自主学习,能使课堂教学效益得到最优化。一、创设悬念情境,使学生在“奇”中“问”数学教师在教学时,要结合小学生 Primary school mathematics is less abstract than other subjects at primary school, and the primary school students themselves have poor understanding skills. As a result, many students are less efficient and less interested in learning mathematics. Therefore, it is necessary to create situational teaching, to concreteize and visualize the abstract mathematical knowledge, to make students feel immersive and to make the transition from the perception of image to the abstract and rational stage. The establishment of situational teaching mode is conducive to stimulating interest in learning, promoting students’ autonomous learning and optimizing teaching effectiveness in classroom. First, the creation of suspense situations so that students in the “odd ” “ask ” mathematics teachers in teaching, we must combine primary school students
