1、小学数学问题情境的误区和对策学院:专业:年级:指导老师:学生姓名:日期:小学数学问题情境的误区和对策摘要小学数学教学中创设问题情境是改革实验教科书的一大亮点,新奇、灵活、巧妙、有趣、富有针对性的问题情境不仅促进学生的数学思考,而且使教学如鱼得水,取得事半功倍的良效。相反,问题情境的创设华而不实、离题万里、枯燥乏味、牵强附会便会事与愿违,适得其反,这样不仅冲淡了数学课应有的数学味,可能还会导致课堂教学目标未能及时实现,从而影响教学的进度。本文针对新课改下教师在创设问题情境时,缺失实效性、目的性、趣味性、数学性、科学性诸多误区进行反思和分析,然后详细诠释问题情境正确理
2、解问题情境,最后提出通过变花哨为内涵,精选信息,设计矛盾、趣味和悬念的问题情境,凸显情境的数学味,紧扣学科教学目标等多种创设有效问题情境的对策,进而让教师们正确理解问题情境,尽快走出创设的误区。关键词:小学数学;问题情境;误区;对策TheErroneousZonesandCountermeasuresofCreatingProblem-SituationinElementarySchoolMathAbstract:Thecreationofproblemsituationsinprimaryschoolmathematicsteachingisoneofthehi
