【摘要】 代数在初中数学学科中占据着非常重要的位置,它在整个初中数学中都是不可缺少的一部分.例题是数学课堂的重要组成部分,学生通过代数例题的学习能更容易的去掌握基本的数学知识和技能,而且为以后的学习奠定了重要的基础.学生学习并掌握代数知识的重要方式之一就是来源于教师代数例题的教学,代数例题教学的高效性对于教师和学生来说都是一种鼓励和肯定.因此,代数例题教学的案例分析在数学课堂教学中具有十分重要的实际意义.全文共六章,第一章主要是对问题的提出、研究的背景与意义进行了简单的说明,并阐述了研究的方法及思路.第二章是简单阐述了研究的理论依据,范例教学理论和建构主义学习理论.第三章是阐述了新课标下的初中代数,代数例题的功能以及代数例题的教学原则,体现出代数例题在教学中的重要性.第四章是对作者所在的学校的初一学生和全体教师进行了问卷调查,并根据调查的结果,从三个角度进行了分析.第五章从实数、代数式、方程、不等式、函数几个方面进行了案例分析.第六章是对所得结论的一个总结以及不足之处和需要进一步研究的方向.根据以上几方面的研究,得出初中代数例题教学的重要性,并期望代数例题教学能得到落实,学生对代数例题的学习能有极大的兴趣.更多还原

【Abstract】 Algebra occupies a very important position in the junior middle school mathematics subject,it is an indispensable part in the entire junior middle school mathematics.The example problem is an important part of the mathematics classroom,it can not only help students master the basic mathematical knowledge and skills,but also help Students acquire basic mathematical experience and mathematical ideas.Algebra example teaching is an important channel and method to obtain algebra knowledge.The effectiveness of algebra example teaching is affirmation for teachers and students.Therefore,the case of algebra example teaching Analysis has very important practical significance.The full text consists of six chapters.The first chapter is mainly to briefly introduce the problem,the background and significance of the research,and the research methods and ideas.The second chapter is to briefly explain the theoretical basis of the research and the example teaching theory.And constructivist learning theory.The third chapter describes the junior high school algebra under the new curriculum standard,the functions of algebra example questions and the teaching principles of algebra example questions,and reflects the importance of algebra example questions in teaching.The junior high school students and all teachers of the school conducted a questionnaire survey,and based on the results of the survey,analyzed from three perspectives.Chapter 5 analyzes cases from the aspects of real numbers,algebraic formulas,equations,inequality and functions.The chapter is a summary of the conclusions obtained,as well as the shortcomings and directions that need further research.Based on the research in the above aspects,the importance of algebra exampleteaching in junior high school is obtained,and it is expected that the algebra example teaching will be implemented,and students will have great interest in learning algebra example problems.更多还原
