摘  要:随着知识经济的到来,传统教育的弊端日益凸显。新课程的实施,课程目标和功能的调整,使传统教学模式面临着改革。《义务教育数学课程标准(2011版)》提倡“问题情境——建立模型——求解验证”的课堂教学模式。在小学数学课堂教学中,情境创设成为了该模式的关键所在。研究小学数学教学情境创设其实质就是推动情境教学更好地走入课堂,帮助教师转变原有的教学理念和手段,以适应“数学难教,数学难学”的现状。

   本论文主要从以下五个部分进行论述:第一部分是绪论,主要阐述了论文的研究背景,研究现状综述,研究的目的和意义以及本文的研究内容。第二部分是研究理论概述,主要阐述了情境,情境教学以及情境创设的内涵以及迁移理论,最近发展区理论,建构主义理论。第三部分是阐述当前小学数学教学情境创设存在的主要问题以及相关的原因解析:情境创设远离于课堂教学内容;情境创设的形式单一、内容单调、情境功能狭窄;情境创设过程中“兴趣化”高于“数学化”;情境创设脱离学生的生活实际,缺乏真实性。第四部分是创设小学数学教学情境的基本策略:力求精简,围绕教学内容设计教学情境;以多种形式结合各种辅助工具展开情境创设;处理好情境兴趣化与数学化的关系;创设贴近学生生活的情境。第五部分是结语。

关键词:情境;情镜教学;情境创设

 

ABSTRACT:With the advent of the knowledge economy and drawbacks of traditional education is increasingly prominent.Implementation of new courses, course objectives and functions of adjustment facing the traditional teaching mode reform.Compulsory education mathematics curriculum standards (2011 edition) advocated "problem situation--establishment-the solution validation" classroom teaching mode.Situation of research on maths class in its essence is to promote situational teaching better walk into the classroom, teaching ideas and tools to help teachers change the original to accommodate "difficult to teach mathematics, mathematics hard to learn" status.

   This essay is mainly written in following five parts:part1 is introduction, which includes study background,brief introduction of current situation, study aim ,significance and the study content of this essay. Part2 is the study of theory, focuses on situational, connotation of situated teaching and creating situations as well as migration theory, theory of zone of proximal development, theory of Constructivism.Part3 Set out the current main problems of creating situations for mathematics teaching in primary schools, as well as related reasons:creating situations away from content in classroom teaching;Creating situations in the form of a single, monotonous, situational features narrow;In the process of creating situations "of interest" above "mathematical";Creating situations out of student life, the lack of authenticity .Part4 is the basic strategy of creating situations for mathematics teaching in primary schools: a simple way and designed around the teaching content teaching situation;In a variety of form combined with a variety of accessibility situation; Dealing with relationship to life and mathematics;Coordination with students ' actual situation, creating close to the students ' lives.Part5 is the conclusion.

Keywords: Situation;Situational teaching;Creating situations
